AM26C31IDG4 Equivalent & Substitute Parts

Part Overview

The AM26C31IDG4 is a 4/0 driver interface IC manufactured by Texas Instruments in a 16-SOIC surface mount package. This component operates within a 4.5V to 5.5V supply voltage range and supports operating temperatures from -40°C to 85°C. The part is currently in Last Time Buy status, indicating end-of-life production. Identifying equivalent and substitute parts is necessary to ensure design continuity and maintain supply chain reliability for applications requiring this driver functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM26C31IDG4 is determined by strict alignment with the following parameters:

• Driver/Receiver Configuration: 4/0 (four drivers, zero receivers)
• Supply Voltage Range: 4.5V ~ 5.5V
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 16-SOIC surface mount
• Compliance: ROHS3 compliant

All substitute parts listed maintain these core electrical and mechanical specifications. Variations in product status, packaging format (tube vs. cut tape), and protocol support do not affect functional substitutability within the defined parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Texas Instruments)

DS26C31TM/NOPB and DS26C31TMX/NOPB are direct functional equivalents from the same manufacturer with active product status. Both maintain identical electrical specifications and package dimensions. The primary distinction is packaging format: DS26C31TM/NOPB is supplied in tube packaging, while DS26C31TMX/NOPB is supplied in cut tape and digi-reel format. Selection between these variants depends on procurement and assembly requirements.

AM26C31IDR is a manufacturer-recommended substitute within the same AM26C31 base product family, supplied in cut tape and digi-reel format with active product status.

Alternative Substitute (STMicroelectronics)

ST26C31BDR is a cross-manufacturer equivalent from STMicroelectronics with identical electrical and package specifications. This part maintains ROHS3 compliance and operates within the same voltage and temperature ranges. The moisture sensitivity level differs at MSL 3 (168 hours) compared to MSL 1 (unlimited) for the primary substitutes, which may impact storage and handling procedures depending on assembly environment requirements.

Frequently Asked Questions (FAQ)

Q: Can DS26C31TM/NOPB directly replace AM26C31IDG4 in existing designs?

A: Yes. Both parts share identical electrical specifications (4/0 driver configuration, 4.5V–5.5V supply, -40°C to 85°C operating range) and package geometry (16-SOIC). No circuit modifications are required.

Q: What is the difference between DS26C31TM/NOPB and DS26C31TMX/NOPB?

A: Both parts are electrically and mechanically identical. The difference is packaging format: DS26C31TM/NOPB is supplied in tube packaging, while DS26C31TMX/NOPB is supplied in cut tape and digi-reel format. Selection depends on assembly line requirements and procurement preferences.

Q: Is ST26C31BDR suitable as a substitute?

A: ST26C31BDR meets all core electrical and mechanical requirements. The moisture sensitivity level (MSL 3, 168 hours) differs from the primary substitutes (MSL 1, unlimited). This affects storage and handling protocols but does not impact functional performance in the application.

Q: Why is AM26C31IDG4 listed as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued production. Substitute parts with Active status (DS26C31TM/NOPB, DS26C31TMX/NOPB, AM26C31IDR, ST26C31BDR) ensure continued availability for new designs and production requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, consistent with the original AM26C31IDG4 specification.
