Product details

CAN transceiver for field swaps and new builds

It's the part you reach for when a CAN node on a motor drive or outdoor controller goes silent and you need a swap that fits the same footprint without re-spinning the board. The 200 mV receiver hysteresis helps reject noise on long or electrically noisy bus runs, which is the usual case in factory-floor or vehicle installations. The E-suffix designates this extended temperature variant versus the I-suffix (-40°C to 85°C) — if your environment sees sustained heat above 85°C, the E/SN is the correct pick.

Active status, no end-of-life worry

RoHS compliance is ROHS3, which covers the ten restricted substances including the four phthalates. No exemption paperwork needed for EU-market equipment.

Pinout and orientation for field work

The 8-SOIC package has the standard 0.154-inch body width and 3.90 mm body width — fits the common SOIC-8 footprint. Orientation is unambiguous with pin 1 marked by a dot or notch on the package top. No hot-air station required; a standard soldering iron and a steady hand get it done on site.

Frequently asked questions

What is the difference between MCP2551-E/SN and MCP2551-I/SN?

The difference is the temperature range. For applications that see sustained temperatures above 85°C — like under-hood automotive or outdoor industrial enclosures — the E/SN is the correct choice.

Is MCP2551-E/SN compatible with 5V logic?

It is not designed for 3.3 V CAN buses without external level shifting.
