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.
MCP23008-E/P is a 8-bit I2C I/O expander from Microchip Technology, orderable in the PDIP-18 package. The ordering code fixes the exact configuration you receive — package, grade and packing — so procurement starts with matching this code character-for-character against your BOM, not just the base series name.
When you request a quote, include the full ordering code, the target packing format (reel, tube, tray or cut tape), your quantity and any date-code or lot requirements. We reconfirm manufacturer, suffix, package, date code and traceability against the actual offered lot before any commercial quote is issued, and every RFQ gets a reply within 24 hours.

Browse existing catalog records — same series first, then the same category and manufacturer. These are not confirmed replacements; compatibility requires engineering review.

Every suffix in a manufacturer ordering code identifies one exact orderable device — package, temperature grade, packing format or a revision. MCP23008-E/P names the PDIP-18 configuration; a code that differs by even one suffix character may be a different device. Always quote the complete code exactly as it appears on your BOM.
The package (PDIP-18) is the physical form of the device itself. Packing describes how the devices are delivered — reel, tube, tray or cut tape. The same ordering code can ship in different packing formats depending on the lot, so confirm the required packing format when you submit your RFQ.
Traceability evidence — lot and date-code information, labels and photos — is confirmed per lot at quotation time, because it depends on the actual lot offered. Tell us which documents your receiving inspection requires when you submit the RFQ, and we will confirm what can be provided for the offered lot.
Add MCP23008-E/P to your RFQ with the complete ordering code, the manufacturer (Microchip Technology), your quantity, the target packing format and any date-code requirements. We reply to every RFQ within 24 hours.
