AM26C31IDE4 Equivalent & Substitute Parts

Part Overview

The AM26C31IDE4 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 the original part number. The AM26C31IDE4 operates within a 4.5V to 5.5V supply voltage range and supports operating temperatures from -40°C to 85°C. Due to its Last Time Buy status, identifying functionally equivalent substitute parts is essential for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AM26C31IDE4 are qualified based on the following criteria:

Electrical Compatibility: All substitute parts maintain identical supply voltage range (4.5V ~ 5.5V) and operating temperature range (-40°C ~ 85°C). All parts feature 4/0 driver/receiver configuration.

Mechanical Compatibility: All substitute parts use the 16-SOIC package form factor with 0.154" (3.90mm) width, ensuring pin-compatible footprint compatibility on PCBs designed for the AM26C31IDE4.

Regulatory Compliance: All substitute parts maintain ROHS3 compliance and EAR99 classification, meeting the same environmental and export requirements as the original part.

Packaging Availability: Substitute parts are available in active production status with higher inventory levels, providing superior long-term availability compared to the Last Time Buy status of the AM26C31IDE4.

Parameter Comparison

Engineering Selection Recommendations

Texas Instruments AM26C31IDR: This part shares the same base product number (AM26C31) as the original AM26C31IDE4 and is available in Active production status. The AM26C31IDR differs only in packaging format (Cut Tape & Digi-Reel versus Tube) and maintains identical electrical and thermal specifications. This part is the manufacturer-recommended substitute.

Texas Instruments DS26C31TM/NOPB and DS26C31TMX/NOPB: Both DS26C31 variants are Active production parts from Texas Instruments with identical electrical parameters, package form factor, and compliance certifications. The DS26C31TMX/NOPB offers significantly higher inventory availability (20338 Pcs) compared to the DS26C31TM/NOPB (1525 Pcs). Both parts are functionally equivalent for applications requiring 4/0 driver configuration within the specified voltage and temperature ranges.

STMicroelectronics ST26C31BDR: This part provides cross-manufacturer substitution with identical electrical specifications and package compatibility. The ST26C31BDR maintains ROHS3 compliance and operates within the same voltage and temperature parameters. Inventory availability is highest among all substitute options (30449 Pcs). The MSL rating differs at level 3 (168 Hours) versus level 1 for Texas Instruments parts, which may impact storage and handling requirements in moisture-sensitive environments.

Frequently Asked Questions (FAQ)

Q: Can AM26C31IDE4 be directly replaced with AM26C31IDR?

A: Yes. Both parts share the base product number AM26C31 and are electrically and mechanically identical. The difference is packaging format only (Tube versus Cut Tape & Digi-Reel). Pin configuration and electrical performance are equivalent.

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

A: Both parts are electrically and mechanically identical. The primary difference is packaging format and inventory availability. DS26C31TMX/NOPB is supplied in Cut Tape & Digi-Reel format with significantly higher stock levels (20338 Pcs versus 1525 Pcs).

Q: Is the ST26C31BDR from STMicroelectronics fully compatible?

A: The ST26C31BDR is electrically and mechanically compatible with the AM26C31IDE4. Both operate at 4.5V to 5.5V supply voltage, support -40°C to 85°C operating temperature, and use the 16-SOIC package. The MSL rating differs (3 versus 1), which affects moisture handling during storage and assembly. This is a cross-manufacturer substitute suitable for applications where moisture sensitivity is not a constraint.

Q: Why is the AM26C31IDE4 marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer is discontinuing this specific part number variant. Substitute parts in Active production status provide long-term availability and supply chain continuity.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance and EAR99 classification, matching the regulatory requirements of the original AM26C31IDE4.
