AM26C31IDR Equivalent & Substitute Parts

Part Overview

The AM26C31IDR is a 4/0 driver interface IC manufactured by Texas Instruments in a 16-SOIC surface mount package. This component is classified as an active product and is ROHS3 compliant. The AM26C31IDR serves as a differential line driver for digital communication applications. Substitute parts are identified when equivalent electrical specifications, mechanical compatibility, and compliance certifications align with the original component, enabling direct replacement in circuit designs without functional degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AM26C31IDR are qualified based on the following criteria:

• Identical number of drivers/receivers configuration (4/0)
• Matching supply voltage range (4.5V ~ 5.5V)
• Identical operating temperature range (-40°C ~ 85°C)
• Compatible package type (16-SOIC or equivalent 16-SO)
• Surface mount mounting type
• Active product status
• ROHS3 compliance certification

The substitute parts DS26C31TM/NOPB, DS26C31TMX/NOPB, and ST26C31BDR meet these electrical and mechanical requirements. Packaging format differences (Tube versus Cut Tape & Digi-Reel®) do not affect functional substitution but may impact procurement and handling procedures.

Parameter Comparison

Engineering Selection Recommendations

All four parts—AM26C31IDR, DS26C31TM/NOPB, DS26C31TMX/NOPB, and ST26C31BDR—are active products with ROHS3 compliance and identical electrical specifications. Selection between these parts should be based on:

• Packaging format availability: AM26C31IDR and DS26C31TMX/NOPB are supplied in Cut Tape & Digi-Reel® format; DS26C31TM/NOPB is supplied in Tube format.
• Moisture sensitivity requirements: AM26C31IDR, DS26C31TM/NOPB, and DS26C31TMX/NOPB have MSL 1 (Unlimited); ST26C31BDR has MSL 3 (168 Hours), requiring controlled storage conditions.
• Manufacturer preference: Texas Instruments parts (AM26C31IDR, DS26C31TM/NOPB, DS26C31TMX/NOPB) or STMicroelectronics (ST26C31BDR).
• Inventory availability and lead time considerations.

Frequently Asked Questions (FAQ)

Q: Can DS26C31TM/NOPB replace AM26C31IDR in production designs?

A: Yes. Both parts share identical electrical specifications (4.5V ~ 5.5V supply, -40°C ~ 85°C operating range, 4/0 driver configuration) and package dimensions (16-SOIC). The primary difference is packaging format (Tube versus Cut Tape & Digi-Reel®), which does not affect functional performance.

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

A: Both parts are functionally equivalent with identical electrical specifications and package type (16-SOIC). The primary difference is packaging format: DS26C31TMX/NOPB is supplied in Cut Tape & Digi-Reel® format, while DS26C31TM/NOPB is supplied in Tube format.

Q: Is ST26C31BDR suitable for applications requiring unlimited moisture exposure?

A: ST26C31BDR has MSL 3 (168 Hours), requiring controlled storage and handling conditions. For applications requiring unlimited moisture exposure without storage restrictions, AM26C31IDR, DS26C31TM/NOPB, or DS26C31TMX/NOPB (all MSL 1) are more appropriate.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. AM26C31IDR, DS26C31TM/NOPB, DS26C31TMX/NOPB, and ST26C31BDR are all ROHS3 compliant.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes, provided the PCB footprint accommodates the 16-SOIC package dimensions (0.154", 3.90mm Width). All four parts use identical pin configurations and electrical interfaces.
