AM26C32IPWR-NM Equivalent & Substitute Parts

Part Overview

The AM26C32IPWR-NM is a 0/4 Receiver IC for RS422 and RS423 serial communication protocols, manufactured by Texas Instruments in a 16-TSSOP surface mount package. This part is classified as Obsolete, indicating it has been discontinued by the manufacturer. Due to its obsolete status, locating original stock may present supply chain challenges. Identifying active equivalent parts ensures design continuity and maintains access to functionally compatible components for new production runs, repairs, and system upgrades.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AM26C32IPWR-NM is determined by strict equivalence across the following critical parameters:

Protocol Compatibility: Both the main part and substitute must support RS422 and RS423 protocols.

Receiver Configuration: The 0/4 receiver configuration (zero drivers, four receivers) must be maintained.

Electrical Specifications: Receiver hysteresis of 60 mV, supply voltage range of 4.5V to 5.5V, and operating temperature range of -40°C to 85°C must be identical.

Package Specification: The 16-TSSOP surface mount package with 0.173" width (4.40mm) is mandatory for mechanical and thermal compatibility.

Compliance Standards: RoHS3 compliance and MSL Level 1 rating must be preserved.

The AM26C32IPWR (without the -NM suffix) from Texas Instruments meets all these criteria and qualifies as a direct substitute. The primary distinction is product status: AM26C32IPWR is Active, whereas AM26C32IPWR-NM is Obsolete.

Engineering Selection Recommendations

The AM26C32IPWR is the appropriate substitute for the obsolete AM26C32IPWR-NM. Selection is based on the following engineering criteria:

Product Status: AM26C32IPWR maintains Active status with the manufacturer, ensuring continued availability and supply chain reliability. The -NM variant has been discontinued, making the standard AM26C32IPWR the current production equivalent.

Functional Equivalence: All electrical and mechanical parameters are identical between the two parts. The receiver configuration, protocol support, hysteresis characteristics, supply voltage range, and operating temperature specifications are unchanged.

Compliance Certification: Both parts maintain ROHS3 compliance and MSL Level 1 rating, satisfying environmental and moisture sensitivity requirements for industrial and commercial applications.

Packaging: The 16-TSSOP surface mount package is consistent, allowing direct substitution without PCB redesign or layout modifications.

For new designs, production runs, and component replenishment, the AM26C32IPWR should be specified. For legacy systems currently using AM26C32IPWR-NM, direct replacement with AM26C32IPWR is electrically and mechanically compatible.

Frequently Asked Questions (FAQ)

Q: Can AM26C32IPWR directly replace AM26C32IPWR-NM in existing designs?

A: Yes. The AM26C32IPWR is electrically and mechanically equivalent to AM26C32IPWR-NM. All critical parameters—protocol support, receiver configuration, hysteresis, supply voltage, operating temperature, and package dimensions—are identical. Direct substitution requires no circuit modifications or PCB redesign.

Q: What is the difference between AM26C32IPWR and AM26C32IPWR-NM?

A: The primary difference is product status. AM26C32IPWR-NM is Obsolete and no longer manufactured. AM26C32IPWR is the Active equivalent from Texas Instruments. The -NM suffix designation has been discontinued, but the base part number AM26C32IPWR remains in production with identical specifications.

Q: Are there any packaging differences between these parts?

A: No. Both parts use the 16-TSSOP surface mount package with 0.173" width (4.40mm). Packaging format options may differ (the substitute offers Cut Tape and Digi-Reel options), but the physical package specification is unchanged.

Q: What protocols does the AM26C32IPWR support?

A: The AM26C32IPWR supports RS422 and RS423 serial communication protocols. It is configured as a 0/4 receiver, meaning it contains four receiver channels with no driver channels.

Q: What is the receiver hysteresis specification?

A: The receiver hysteresis is 60 mV. This specification is identical for both AM26C32IPWR-NM and AM26C32IPWR and determines the input threshold differential for signal detection.

Q: What supply voltage range is required?

A: The supply voltage range is 4.5V to 5.5V. This specification applies to both the obsolete and active variants and must be maintained in circuit design.

Q: Is the AM26C32IPWR RoHS compliant?

A: Yes. The AM26C32IPWR is ROHS3 compliant and carries MSL Level 1 (Unlimited) moisture sensitivity rating, meeting environmental and reliability standards for industrial applications.

Q: What is the maximum data rate?

A: The AM26C32IPWR supports a data rate of 10 Mbps. This specification applies to RS422 and RS423 serial communication at the specified supply voltage and operating temperature range.

Q: What is the operating temperature range?

A: The operating temperature range is -40°C to 85°C (TA). This specification is maintained across both the obsolete AM26C32IPWR-NM and the active AM26C32IPWR.
