MCP2551T-I/SN

MCP2551-I/SN is a Microchip high-speed CAN transceiver in SOIC-8 — for industrial and automotive CAN: the drop-in alternative to the NXP TJA1050 with EMI-tuning capability. Up to 1 Mbps, ISO 11898 compliant, 4.5–5.5 V supply, -40°C to +85°C industrial temp range, externally-controlled slew rate via Rs pin, low-current standby. Heat evidence: CAN transceiver demand spillover from automotive dual-sourcing — Microchip CAN PHYs are being qualified as alternates across industrial designs. Selection advice: the Rs pin for slew-rate control is the differentiator vs the TJA1050 — use it to tune EMI without changing the transceiver; the I-temp grade suits industrial, for under-hood use specify the E-temp variant. Parameters verified against Microchip documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

TJA1050T/CM is an NXP high-speed CAN transceiver in SOIC-8 — note: Mouser lists the TJA1050T/CM,118 ordering code as End of Life (scheduled for obsolescence) — for automotive and industrial CAN networks: the industry-default 1 Mbps PHY for body, chassis and powertrain buses. Fully ISO 11898 compliant, 4.75–5.25 V supply, 3.3/5 V logic compatible, up to 110 nodes per bus, silent (listen-only) mode. Heat evidence: vehicle makers scrambling for Nexperia alternatives are creating spillover tightness in CAN transceivers — the TJA1050 is the benchmark part every CAN design references. Selection advice: the TJA1050 has no standby/wake-up — for low-power nodes needing bus wake-up choose the TJA1042 instead; the /CM code is the SOIC-8 standard package. For new designs the TJA1042 is the recommended successor. Parameters verified against NXP documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ENC28J60-I/SS is a Microchip ENC28J60 stand-alone Ethernet controller with SPI interface — integrated MAC and 10Base-T PHY, 8 KB transmit/receive packet buffer, SPI clock up to 20 MHz, in 28-pin SSOP, tube packing, -40 to +85 °C industrial grade (the I suffix). On-chip MAC plus PHY is the selection point: Ethernet for any microcontroller that has SPI, with internal DMA and hardware checksum assist to keep small MCUs fast. Selection advice: this is 10Base-T only — for 100 Mbps choose a different controller family. You must add external magnetics and an RJ45 jack; the chip handles the protocol, not the magnetics. The 3.1-3.6 V supply with 5 V-tolerant inputs suits 3.3 V logic designs, and the industrial temperature range covers outdoor and factory installations where the commercial (non-I) grade does not. Evidence: Microchip ENC28J60 datasheet (DS39662C) and distributor listings confirm SPI, MAC+PHY, 8 KB RAM, SSOP-28 and -40 to +85 °C. Match the full ENC28J60-I/SS code for grade and package. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

LAN8720A-CP-TR is a Microchip Technology 10BASE-T/100BASE-TX Ethernet PHY transceiver in 24-pin QFN, tape and reel — for embedded network connectivity: printers, set-top boxes and industrial controllers adding 10/100 Ethernet via RMII. Single 3.3 V supply, HP Auto-MDIX and auto-negotiation is the selection point: a small-footprint PHY that just works with any RMII MAC. Selection advice: the TR suffix denotes tape and reel; the A-CP grade covers the 0 °C to +85 °C commercial range — for the −40 °C to +85 °C industrial range, the LAN8720AI variants are the siblings. Lifecycle note: this ordering code is flagged Not Recommended for New Designs — for new designs, ask about the current-generation Microchip PHY as the forward path in your RFQ, and confirm date code and traceability for legacy builds. Parameters verified against distributor and manufacturer documentation. We reconfirm the offered lot before quotation and reply within 24 hours.

LAN9730I-ABZJ is a Microchip LAN9730i High-Speed Inter-Chip (HSIC) USB 2.0 to 10/100 Ethernet controller — integrated 10/100 MAC and PHY with HP Auto-MDIX, in 56-pin VQFN (8 × 8 mm), tray packing (ABZJ; TR is the reel version), single 3.3 V supply, -40 to +85 °C. Single-chip MAC plus PHY is the selection point: one device replaces the MAC-plus-external-PHY two-chip solution for adding Ethernet to embedded hosts. Selection advice: the host interface is HSIC, not standard USB 2.0 — confirm your SoC provides an HSIC port, otherwise choose a USB-based controller (LAN951x family) or an SPI Ethernet controller (ENC28J60) instead. The integrated PHY with auto-MDIX removes the magnetics-configuration headache, and wakeup-packet plus link-status-change detection suits low-power and remote-management designs. Evidence: Microchip LAN9730 datasheet and distributor listings confirm HSIC USB 2.0 to 10/100 Ethernet, integrated MAC+PHY, 56-VQFN and 3.3 V. Match the full LAN9730I-ABZJ code for the industrial grade and tray packing. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

MCP23008-E/P is a Microchip 8-bit I2C I/O expander — 18-pin PDIP, tube, 100/400 kHz I2C, 2.7–5.5 V, up to 125 mA sink on I/O ports, −40 to +125 °C. The I2C port expansion is the selection point: 8 extra GPIOs from two MCU pins — the default expander for keypads, LEDs and slow control signals when the MCU runs out of pins. Selection advice: Microchip lists the MCP23008-E/P as In Production. The E/P suffix pins the extended-temperature PDIP package — match it to your footprint; the same die ships in SOIC and QFN under different suffixes. Note the 125 mA total sink budget is shared across ports — for relay or LED-array drive add a driver stage rather than loading the expander directly. Evidence: Microchip data confirms In Production, 8-bit I2C expander, PDIP-18, tube. Match the full MCP23008-E/P code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

MCP23017-E/SO is a Microchip 16-bit I2C I/O expander in 28-pin SOIC (7.5 mm wide body), tube packing — 1.8 V to 5.5 V supply, I2C bus up to 1.7 MHz in high-speed mode, two 8-bit ports (PORTA/PORTB) configurable as inputs or outputs, 25 mA source/sink per pin, three hardware address pins for up to eight devices on one bus, interrupt-on-change with configurable INTA/INTB outputs, internal pull-ups, polarity inversion, and 8/16-bit bank addressing, −40 to +125 °C (E grade). The combination of 1.7 MHz I2C and 16 independently configurable lines is the selection point: an MCU with two I2C wires gains 16 digital I/Os with interrupt reporting — enough to replace a second microcontroller in keypad, LED-matrix and sensor-hub designs. Selection advice: the E means −40 to +125 °C (the I grade is the narrower industrial range); the SO is the 28-pin wide-body SOIC in tubes — the MCP23017T-E/SO is the tape-and-reel variant. It is I2C only; for the SPI equivalent pick the MCP23S17, not this part. Microchip lists MCP23017-E/SO as In Production. Evidence: Microchip MCP23017 datasheet and distributor listings confirm 1.8–5.5 V, 1.7 MHz, 16 I/O, 25 mA, 28-SOIC and tube packing. Match the full MCP23017-E/SO code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

MCP2515-I/SO is a Microchip Technology stand-alone CAN controller in 18-pin SOIC, tube — for adding CAN 2.0 to any MCU via SPI: automotive accessories, industrial nodes and sensor networks. 10 MHz SPI with three transmit buffers, two receive buffers and hardware acceptance filtering is the selection point: the MCU offloads the entire CAN protocol instead of bit-banging it. Selection advice: the I/SO suffix denotes the industrial −40 °C to +85 °C grade in SOIC-18 — for surface-mount tape and reel, check the TR-suffixed code. Pair it with a CAN transceiver such as the TJA1051T/3/1J on this site — the MCP2515 is the protocol controller, it does not drive the bus itself. Six 29-bit filters plus two masks cut unwanted traffic before it reaches the MCU. 2.7 V to 5.5 V supply. Microchip lists this part as Active. Parameters verified against distributor and manufacturer documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

MCP2515-I/ST is a Microchip MCP2515 stand-alone CAN 2.0B controller with SPI interface — 1 Mbps CAN, two receive buffers with six 29-bit filters and two masks, three transmit buffers, high-speed SPI up to 10 MHz, in 20-pin TSSOP, tube packing, -40 to +85 °C industrial grade (the I suffix). Hardware message filtering is the selection point: unwanted CAN frames are rejected in silicon so the host MCU is not interrupted by irrelevant bus traffic. Selection advice: the MCP2515 is the controller only — pair it with a CAN transceiver (MCP2551/TJA1050 family) to reach the physical bus; for an integrated controller-plus-transceiver choose a different part. It is pin- and function-compatible with the older MCP2510 per Microchip, easing upgrades. The 2.7-5.5 V supply covers both 3.3 V and 5 V logic designs, and the industrial grade suits automotive and factory environments. Evidence: Microchip MCP2515 datasheet (DS21801E) and distributor listings confirm CAN 2.0B, SPI, TSSOP-20 and tube packing. Match the full MCP2515-I/ST code for grade and package. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ADUM1201ARZ is an Analog Devices ADuM1201 dual-channel digital isolator in 8-lead narrow-body SOIC — 1/1 channel direction configuration, 1 Mbps data rate, 2500 Vrms isolation, 2.7 to 5.5 V supplies with 3 V/5 V level translation, tube packing (ARZ; ARZ-RL7 is the reel version), -40 to +105 °C. The 1/1 direction is the selection point: one channel each way for full-duplex signals like UART Tx/Rx or single-wire buses, using iCoupler magnetic coupling instead of LEDs — no optocoupler aging and 25 kV/µs transient immunity. Selection advice: for two channels in the same direction choose ADuM1200, not ADuM1201; match the ARZ code for tube packing. For SPI or high-speed data isolation choose a higher-rate iCoupler grade. Analog Devices lists this code as Active. Evidence: ADuM1200/ADuM1201 datasheet and DigiKey listings confirm 1 Mbps, 1/1 direction, 2500 Vrms, 8-SOIC tube packing and -40 to +105 °C. Match the full ADUM1201ARZ code for direction and packing. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.
