MCP9808T-E/MC

DS18B20 is an Analog Devices/Maxim 1-Wire digital thermometer — programmable 9–12 bit resolution, ±0.5 °C accuracy (−10 to +85 °C), −55 to +125 °C range, 3–5.5 V supply, 3-pin TO-92. The 1-Wire bus is the selection point: dozens of sensors share one MCU pin with unique 64-bit IDs — the default temperature sensor for multi-point monitoring. Selection advice: order-code warning — the bare DS18B20 (tin-lead, no + suffix) is listed as Obsolete and RoHS non-compliant by distributors; the lead-free DS18B20+ is the production variant (DigiKey lists it as the direct substitute with stock). For new designs always specify the DS18B20+ — the bare code will fail RoHS compliance. For parasite-power mode verify the pull-up and timing against the datasheet. Evidence: DigiKey confirms bare DS18B20 Obsolete/RoHS non-compliant and DS18B20+ as direct substitute; ADI data confirms 12-bit, ±0.5 °C, TO-92. Match the full code including the + suffix.

Analog Devices lists DS18B20+ as a PRODUCTION programmable-resolution 1-Wire digital thermometer, -55 to +125 °C range, ±0.5 °C accuracy (-10 to +85 °C), 9 to 12-bit resolution. The 1-Wire interface is the procurement advantage: dozens of sensors share a single data line with unique 64-bit IDs, which slashes wiring cost in multi-point temperature monitoring. Selection advice: the + denotes the lead-free configuration in the TO-92-3 through-hole package — the DS18B20 also ships in SO and other SMD packages, so match the full DS18B20+ code to your assembly process. Each device carries a factory-programmed unique ID, which your firmware uses for bus addressing; confirm your resolution setting (9–12 bit trades speed for precision) during design.

LM75AD,118 is a digital temperature sensor from NXP Semiconductors in SOIC-8 — I2C interface, ±2 °C accuracy, 2.8 to 5.5 V, 11-bit resolution with thermal watchdog output. NXP flags this code Not Recommended for New Designs. The thermal watchdog output is the selection point: it signals overtemperature directly without host polling, for thermal protection circuits. Selection advice: because NXP flags this code NRND, treat it as a legacy reference — for new designs qualify a current-production I2C temperature sensor before committing the BOM; for existing builds, send quantity and date-code requirements with your RFQ and we will check remaining traceable stock. Parameters verified against the NXP official product page. We reconfirm the offered lot before quotation and reply within 24 hours.

TMP117AIDRVR is a high-accuracy digital temperature sensor from Texas Instruments in a 6-pin WSON package, with an I2C interface — for precision thermal monitoring in medical, industrial and test equipment. High accuracy without calibration is the selection point: where an NTC thermistor needs per-unit calibration, the TMP117 delivers calibrated digital readings out of the box, removing a production step. Selection advice: the DRVR suffix denotes the WSON-6 package on tape and reel — match the full code to your layout. Confirm your accuracy requirement against the datasheet before paying for precision you do not need; for coarse monitoring a cheaper sensor suffices. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

SHT30-ARP-B is an analog-output humidity and temperature sensor from Sensirion in a 2.5 × 2.5 × 0.9 mm DFN package — ±3 %RH and ±0.3 °C typical accuracy on a 2.4–5.5 V supply. The analog ratiometric output is the selection point within the SHT30 family: it feeds a plain ADC channel with no I2C stack, for cost-driven designs that already have analog inputs free. Selection advice: the ARP-B suffix denotes the analog-output variant — do not confuse it with the digital I2C DIS variants, which are not interchangeable. Match the full SHT30-ARP-B code. Parameters verified against the Sensirion official product page. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

Sensirion lists SHT30-DIS-B as Active — a digital humidity and temperature sensor with ±2 %RH accuracy (10–90 %RH), I2C interface, 2.15–5.5 V supply, -40 to +125 °C, DFN-8 2.5 × 2.5 × 0.9 mm package. Factory calibration is the advantage: each sensor ships calibrated with the calibration data on-chip, so humidity readings are accurate without production-line calibration. Selection advice: the DIS-B code denotes the I2C variant in DFN-8 — Sensirion ships analog and I2C variants that are not interchangeable, so match the full SHT30-DIS-B code. For condensing or harsh environments, confirm your protection (membrane/filter) requirements; the bare sensor is for non-condensing use. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

SHT30-DIS-B2.5KS is a digital humidity and temperature sensor from Sensirion in a DFN-8 package, with I2C interface on tape and reel — for cost-driven HVAC, appliances and environmental monitoring. The SHT30 is the selection point for budget humidity sensing: Sensirion calibration quality at the lowest price in the family, with I2C for easy host integration. Selection advice: the 2.5KS suffix denotes the accuracy grade and reel packing — match the full SHT30-DIS-B2.5KS code. For tighter accuracy, the SHT31 is the drop-in upgrade in the same footprint. Confirm your RH accuracy needs against the datasheet before choosing. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

SHT31-DIS-B2.5KS is a digital humidity and temperature sensor from Sensirion in a DFN-8 package, with factory-calibrated output — for HVAC, environmental monitoring and consumer appliances. The factory calibration is the selection point: ±2% RH accuracy out of the box with no production calibration step, which removes test time from your line. Selection advice: the 2.5KS suffix denotes the accuracy grade and tape-and-reel packing — match the full SHT31-DIS-B2.5KS code. For tighter accuracy, step up within the SHT3x family; for cost-driven designs, the SHT30 is the drop-in alternative. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ACS37002LMABTR-050B5 is an isolated Hall-effect current sensor from Allegro MicroSystems in a 16-pin SOIC package, with a 50 A measurement range on tape and reel — for high-current motor drives, solar inverters and industrial power. The 50 A range in a standard SOIC-16 is the selection point: high-current isolated sensing without a bulky module or external shunt. Selection advice: the 050B5 code denotes the 50 A bidirectional variant — the ACS37002 ships in multiple ranges that are not interchangeable, so match the full ACS37002LMABTR-050B5 code. Confirm your current range, bandwidth and isolation requirements against the datasheet. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ACS712ELCTR-05B-T is an isolated Hall-effect current sensor from Allegro MicroSystems in an 8-pin SOIC package, with a 5 A measurement range — for motor control, power supplies and overcurrent protection. The integrated Hall sensor with 2.1 kV isolation is the selection point: current sensing with galvanic isolation and no shunt resistor, so no power dissipation or high-side measurement headaches. Selection advice: the 05B code denotes the ±5 A range — the ACS712 ships in 5/20/30 A variants with different sensitivities that are not interchangeable, so match the full ACS712ELCTR-05B-T code. Confirm your current range and bandwidth needs against the datasheet. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.
