MAX231CPD Equivalent & Substitute Parts

Part Overview

The MAX231CPD is a 2/2 transceiver IC implementing full RS232 protocol functionality in a 14-pin DIP package. This component is classified as obsolete, which necessitates identification of equivalent substitute parts for ongoing system support and new designs. The MAX231CPD provides bidirectional RS232 communication with dual drivers and receivers, operating from 5V to 13.2V supply voltage and supporting data rates up to 250kbps.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX231CPD is determined by strict equivalence across the following critical parameters:

• Protocol specification: RS232
• Channel configuration: 2 drivers and 2 receivers (2/2 topology)
• Duplex mode: Full duplex operation
• Receiver hysteresis: 500 mV
• Data rate capability: 250kbps minimum
• Supply voltage range: 5V, 7.5V ~ 13.2V
• Package form factor: 14-DIP (0.300", 7.62mm)
• Mounting technology: Through Hole

The MAX231CPD+ meets all these parameters and qualifies as a parametric equivalent. The primary distinction between these parts is product status and compliance certification, not functional or electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The MAX231CPD+ is the direct substitute for the MAX231CPD. Both parts are electrically and mechanically identical across all functional parameters. The MAX231CPD+ is preferred for new designs and ongoing production due to its active product status and ROHS3 compliance certification. The MAX231CPD is obsolete and should be replaced in inventory management and procurement planning.

For applications requiring the MAX231CPD, the MAX231CPD+ provides equivalent performance without design modification or PCB rework, as both parts share identical pinout, package dimensions, and electrical specifications.

Frequently Asked Questions (FAQ)

Q: Can MAX231CPD+ directly replace MAX231CPD in existing designs?

A: Yes. The MAX231CPD+ is a direct pin-for-pin and functionally equivalent substitute. No circuit modifications or PCB changes are required for substitution.
