AM26C31IDRE4 Equivalent & Substitute Parts

Part Overview

The AM26C31IDRE4 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 limited availability of this specific packaging configuration (Tape & Reel). 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 transitions, allowing engineers to maintain design continuity while sourcing from active product lines.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM26C31IDRE4 is determined by the following critical parameters: identical package type (16-SOIC), matching driver/receiver configuration (4/0), compatible supply voltage range (4.5V ~ 5.5V), and surface mount mounting type. All substitute parts listed maintain these core electrical and mechanical specifications. Substitutes are grouped into two categories: direct functional equivalents from Texas Instruments with active product status, and cross-manufacturer alternatives that meet identical electrical and package requirements.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring immediate sourcing, DS26C31TMX/NOPB and AM26C31IDR are preferred substitutes due to their active product status and highest inventory availability (20,338 and 20,100 units respectively). Both parts maintain identical electrical specifications and package requirements as the AM26C31IDRE4.

AM26C31QDR offers an extended operating temperature range (-40°C to 125°C) compared to the original part, making it suitable for applications requiring higher temperature performance while maintaining all other electrical and mechanical compatibility.

DS26C31TM/NOPB and DS26C31TMX/NOPB include RS422 and RS485 protocol support, providing additional functional capability within the same package footprint and electrical specifications.

ST26C31BDR from STMicroelectronics is a direct functional equivalent with active product status and substantial inventory (30,449 units). The primary consideration is its Moisture Sensitivity Level of 3 (168 hours) compared to MSL 1 for Texas Instruments variants, which may impact storage and handling requirements in high-humidity environments.

All substitute parts maintain ROHS3 compliance and EAR99 export classification consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can AM26C31IDR be used as a direct replacement for AM26C31IDRE4?

A: Yes. Both parts share identical electrical specifications (4.5V ~ 5.5V supply, -40°C ~ 85°C operating range), driver/receiver configuration (4/0), and 16-SOIC package. The primary difference is packaging format: AM26C31IDRE4 is supplied in Tape & Reel, while AM26C31IDR is supplied in Cut Tape & Digi-Reel format. Electrical and mechanical compatibility is complete.

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

A: Both parts are electrically identical with matching 4/0 driver configuration, 16-SOIC package, and 4.5V ~ 5.5V supply voltage. The difference is packaging: DS26C31TM/NOPB is supplied in Tube format, while DS26C31TMX/NOPB is supplied in Cut Tape & Digi-Reel format. Selection depends on procurement and assembly requirements.

Q: Why does AM26C31QDR have a different operating temperature range?

A: AM26C31QDR is rated for -40°C to 125°C operation, compared to -40°C to 85°C for AM26C31IDRE4. This extended range does not affect substitution compatibility; it indicates the part is qualified for higher temperature applications. All other electrical and package specifications remain identical.

Q: Is ST26C31BDR suitable for moisture-sensitive applications?

A: ST26C31BDR has Moisture Sensitivity Level 3 (168 hours), requiring controlled storage conditions, compared to MSL 1 (unlimited) for Texas Instruments variants. In applications with strict moisture control requirements or extended storage periods, Texas Instruments alternatives are preferred. For standard manufacturing environments with proper handling, ST26C31BDR is functionally equivalent.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (DS26C31TM/NOPB, DS26C31TMX/NOPB, AM26C31IDR, AM26C31QDR, and ST26C31BDR) maintain ROHS3 compliance consistent with the original AM26C31IDRE4.
