FFF CompatibilityThe pin assignments, pin names, and overall physical packaging are 100% identical, making it a seamless drop-in replacement.Housed in the identical 16-pin SOIC Wide (DW) package with the same dimensions.Matches all electrical, speed, voltage supply, and temperature range (-40°C to 85°C) requirements.Physically pin-compatible, but the datasheet utilizes different pin naming conventions (e.g., V+/V- instead of VS+/VS-, and T1OUT/R1IN instead of DOUT1/RIN1).Housed in the equivalent 16-pin Wide SO (7.50mm body width) package.Maximum data rate is limited to 120 kbps, which is lower than the original part's 250 kbps speed rating.
AI Summary

MAX232EIDWR by Texas Instruments: 2/2 Transceiver Full RS232 16-SOIC.

This is a direct parametric and pin-compatible equivalent from Texas Instruments. It maintains the identical 250 kbps speed capability and robust ESD protection.

  • Direct pin-to-pin and footprint drop-in replacement requiring zero board layout changes.
  • Identical pin names, electrical limits, and capacitive charge-pump requirements (1µF).
  • Maintains the same high-speed 250 kbps data rate and ±15kV ESD protection.

This is a highly reliable alternative from the original designer family of the MAX232 series, though limited to 120 kbps. It is pin-compatible but uses slightly different pin names in the documentation.

  • Industry-standard high-reliability transceiver from Analog Devices (formerly Maxim).
  • Features matching ±15kV HBM and IEC61000-4-2 ESD protection on RS-232 bus lines.
  • Utilizes identical 1µF external charge-pump capacitors.
  • Lower maximum data rate of 120 kbps vs 250 kbps.
  • Different pin naming terminology used in the manufacturer's datasheet.

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
