Parameter Comparison

Engineering Selection Recommendations

AM26C32IPWR (Texas Instruments): This part is the direct Texas Instruments equivalent with active product status and higher inventory availability (20,305 pcs). It maintains identical electrical specifications and package configuration. Selection of this substitute ensures continuity with the original manufacturer while securing long-term supply.

ST26C32ABTR (STMicroelectronics): This cross-manufacturer substitute from STMicroelectronics provides equivalent functionality with active product status and documented 20 Mbps data rate specification. It meets all electrical and mechanical requirements for direct substitution. This option is suitable when Texas Instruments parts are unavailable or when multi-source qualification is required.

Both substitutes carry ROHS3 compliance and REACH unaffected status, matching the original part's regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can AM26C32IPWR be used as a direct replacement for AM26C32IPWRG4?

A: Yes. Both parts share identical electrical specifications (60 mV hysteresis, 4.5V-5.5V supply, -40°C to 85°C operating range), receiver configuration (0/4), protocol support (RS422/RS423), and 16-TSSOP package dimensions. The primary difference is product status: AM26C32IPWR is active with higher inventory availability.

Q: What is the difference between AM26C32IPWRG4 and AM26C32IPWR?

A: Both are Texas Instruments AM26C32 receivers with identical functional specifications. The suffix variation reflects different packaging or distribution channels. AM26C32IPWR is currently active in production, while AM26C32IPWRG4 is discontinued.

Q: Is ST26C32ABTR compatible with designs using AM26C32IPWRG4?

A: Yes. ST26C32ABTR meets all critical substitution parameters: 0/4 receiver configuration, RS422/RS423 protocol support, 60 mV hysteresis, 4.5V-5.5V supply voltage, -40°C to 85°C operating temperature, and 16-TSSOP package. The documented 20 Mbps data rate specification provides additional performance clarity.

Q: Are there any package or pinout differences between these substitutes?

A: No. All three parts use the 16-TSSOP package with identical 0.173" width and 4.40mm dimensions, ensuring direct PCB compatibility without layout modifications.

Q: Do all substitutes meet the same compliance requirements?

A: Yes. AM26C32IPWR and ST26C32ABTR both carry ROHS3 compliance and REACH unaffected status, matching the original AM26C32IPWRG4 specifications.

Q: Which substitute should be selected for new designs?

A: Both AM26C32IPWR and ST26C32ABTR are suitable for new designs. AM26C32IPWR maintains single-source continuity with Texas Instruments. ST26C32ABTR provides cross-manufacturer qualification for supply chain resilience.
