AM26C31QDR Equivalent & Substitute Parts

Part Overview

The AM26C31QDR 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 with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical specifications, package compatibility, and operational parameters align with the original component, enabling direct replacement in circuit designs without functional degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AM26C31QDR are qualified based on the following critical parameters:

• Electrical Compatibility: Voltage supply range 4.5V ~ 5.5V
• Functional Equivalence: 4/0 Driver configuration (4 drivers, 0 receivers)
• Package Compatibility: 16-SOIC surface mount package with 0.154" width (3.90mm)
• Compliance Status: ROHS3 compliant, active product status
• Thermal Range: Operating temperature specifications must support the application requirements

The substitute parts DS26C31TM/NOPB, DS26C31TMX/NOPB, and ST26C31BDR meet these core substitution criteria. Variations in operating temperature range, packaging format, and moisture sensitivity level are noted but do not preclude functional substitution when application requirements are within the specified limits.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory alignment with the original AM26C31QDR. The primary differentiation factor is operating temperature range: the AM26C31QDR supports -40°C ~ 125°C, while DS26C31TM/NOPB, DS26C31TMX/NOPB, and ST26C31BDR are rated to -40°C ~ 85°C. Selection should be based on application thermal requirements within these specified limits.

The DS26C31TMX/NOPB variant offers the highest inventory availability (20,338 pcs) in Cut Tape & Digi-Reel packaging format. The ST26C31BDR from STMicroelectronics provides an alternative source with equivalent electrical specifications and the largest inventory stock (30,449 pcs), though moisture sensitivity level is rated at MSL 3 (168 Hours) compared to MSL 1 (Unlimited) for other options.

Frequently Asked Questions (FAQ)

Q: Can DS26C31TM/NOPB replace AM26C31QDR in all applications?

A: DS26C31TM/NOPB is electrically and functionally equivalent within the specified operating temperature range of -40°C ~ 85°C. Applications requiring operation above 85°C must use the AM26C31QDR or verify that the substitute's thermal rating is sufficient.

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

A: Both parts are functionally identical with matching electrical specifications and operating temperature ranges. The primary difference is packaging format: DS26C31TM/NOPB is supplied in Tube packaging, while DS26C31TMX/NOPB is supplied in Cut Tape & Digi-Reel format.

Q: Is ST26C31BDR compatible with the AM26C31QDR package footprint?

A: Yes. ST26C31BDR uses a 16-SOIC package with 0.154" width (3.90mm), matching the AM26C31QDR footprint. The supplier device package designation (16-SO vs. 16-SOIC) reflects manufacturer nomenclature but represents the same physical package.

Q: Does moisture sensitivity level affect substitution suitability?

A: Moisture sensitivity level (MSL) affects component handling and storage requirements. AM26C31QDR and Texas Instruments DS26C31 variants have MSL 1 (Unlimited), while ST26C31BDR has MSL 3 (168 Hours). Selection depends on manufacturing process capabilities and storage conditions.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, ensuring regulatory alignment with the original AM26C31QDR for applications requiring environmental compliance certification.
