AM26C32IN Equivalent & Substitute Parts

Part Overview

The AM26C32IN is a 0/4 Receiver IC for RS422 and RS423 serial communication protocols, manufactured by Texas Instruments in a 16-DIP through-hole package. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for new designs or component replenishment. The AM26C32IN maintains full electrical and mechanical compatibility with active substitute options that preserve the core receiver functionality while offering different packaging configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AM26C32IN is determined by strict equivalence across the following electrical and mechanical parameters:

• Protocol Compatibility: Both main and substitute parts must support RS422 and RS423 protocols
• Receiver Configuration: Identical 0/4 driver/receiver count
• Receiver Hysteresis: Fixed at 60 mV across all equivalent parts
• Supply Voltage: 4.5V to 5.5V operating range
• Temperature Range: -40°C to 85°C operational limits
• Base Product Number: AM26C32 series designation
• Compliance Standards: ROHS3 compliance and REACH unaffected status maintained

The AM26C32IDR represents the manufacturer-recommended substitute, sharing identical electrical specifications while differing only in mounting technology (surface mount versus through-hole) and product status (active versus obsolete).

Parameter Comparison

Engineering Selection Recommendations

The AM26C32IDR is the direct functional equivalent of the AM26C32IN, with identical electrical performance across all specified parameters. Selection between these parts is determined by application requirements:

Through-Hole Applications: The AM26C32IN remains suitable for existing designs utilizing DIP sockets or through-hole PCB layouts, subject to availability constraints due to obsolete status.

New Designs and Surface Mount Applications: The AM26C32IDR is the preferred selection, offering active product status with continuous manufacturer support and supply availability. The 16-SOIC package reduces board footprint while maintaining electrical equivalence.

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can AM26C32IDR replace AM26C32IN in existing designs?

A: Electrical replacement is complete. Physical replacement requires PCB redesign to accommodate the 16-SOIC surface-mount package instead of the 16-DIP through-hole package. Pin-to-pin functional equivalence is maintained.

Q: What is the primary reason for substitution?

A: The AM26C32IN is classified as obsolete. The AM26C32IDR provides identical electrical functionality with active product status and established supply chains.

Q: Are there differences in receiver performance?

A: No. Both parts maintain 60 mV receiver hysteresis, identical supply voltage ranges (4.5V to 5.5V), and equivalent operating temperature specifications (-40°C to 85°C).

Q: Do both parts support the same communication protocols?

A: Yes. Both AM26C32IN and AM26C32IDR support RS422 and RS423 protocols with identical 0/4 receiver configuration.

Q: What packaging considerations apply to substitution?

A: The AM26C32IN uses 16-DIP through-hole packaging (0.300" width). The AM26C32IDR uses 16-SOIC surface-mount packaging (0.154" width). PCB layout and assembly process compatibility must be evaluated for each application.

Q: Are compliance certifications maintained across both parts?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, maintaining regulatory requirements for industrial applications.
