AM26C31IDRG4 Equivalent & Substitute Parts

Part Overview

The AM26C31IDRG4 is a 4/0 driver interface IC manufactured by Texas Instruments in a 16-SOIC surface mount package. This component is classified as Last Time Buy, indicating discontinued production with limited remaining inventory. The part operates within a 4.5V to 5.5V supply voltage range and supports operating temperatures from -40°C to 85°C. Equivalent and substitute parts are necessary due to inventory constraints and product lifecycle status, ensuring design continuity and procurement flexibility for applications requiring compatible 4/0 driver functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM26C31IDRG4 is determined by the following critical parameters: identical 4/0 driver/receiver configuration, 16-SOIC package compatibility, surface mount mounting type, 4.5V to 5.5V supply voltage range, and -40°C to 85°C operating temperature range. All substitute parts listed maintain these core electrical and mechanical specifications, ensuring functional interchangeability within the specified operating conditions. Packaging format variations (Tape & Reel, Tube, Cut Tape) do not affect electrical compatibility but may influence procurement and assembly workflows.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, consistent with the AM26C31IDRG4. Texas Instruments parts DS26C31TM/NOPB, DS26C31TMX/NOPB, AM26C31IDR, and AM26C31QDR are classified as Active products with full production support and inventory availability. The AM26C31QDR variant extends the operating temperature range to -40°C to 125°C, providing enhanced thermal performance for demanding applications. The STMicroelectronics ST26C31BDR offers equivalent functionality with Active product status and substantial inventory levels. Selection should prioritize Active status parts to ensure long-term supply chain stability and manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can AM26C31IDR directly replace AM26C31IDRG4 in production? A: Yes. Both parts share identical electrical specifications (4/0 driver configuration, 4.5V to 5.5V supply, -40°C to 85°C operating range) and 16-SOIC package geometry. The primary difference is packaging format (Cut Tape vs. Tape & Reel), which does not affect circuit-level compatibility.

Q: What is the difference between AM26C31IDR and AM26C31QDR? A: Both parts are functionally equivalent with identical driver/receiver configuration and package. AM26C31QDR supports an extended operating temperature range of -40°C to 125°C, compared to -40°C to 85°C for AM26C31IDR. Selection depends on thermal requirements of the target application.

Q: Are DS26C31TM/NOPB and DS26C31TMX/NOPB interchangeable? A: Yes. Both parts are electrically identical with 4/0 driver configuration, RS422/RS485 protocol support, and 16-SOIC packaging. The difference is packaging format: DS26C31TM/NOPB is supplied in Tube format, while DS26C31TMX/NOPB is supplied in Cut Tape & Digi-Reel® format.

Q: Can ST26C31BDR from STMicroelectronics replace Texas Instruments parts? A: Yes. ST26C31BDR meets all core substitution criteria: 4/0 driver configuration, 16-SOIC package, 4.5V to 5.5V supply voltage, and -40°C to 85°C operating temperature. It is ROHS3 compliant and carries Active product status with high inventory availability.

Q: Does packaging format affect electrical performance? A: No. Tape & Reel, Tube, and Cut Tape formats are packaging and delivery methods only. They do not alter electrical characteristics, performance, or circuit compatibility. Selection should be based on assembly line requirements and procurement preferences.

Q: Why is AM26C31IDRG4 classified as Last Time Buy? A: Last Time Buy status indicates the manufacturer has discontinued production. Existing inventory is available for purchase, but no future production is planned. Transition to Active substitute parts such as AM26C31IDR or DS26C31TMX/NOPB is recommended for new designs and long-term supply security.
