AM26C32CNSR-P Equivalent & Substitute Parts

Part Overview

The AM26C32CNSR-P is a quad receiver integrated circuit manufactured by Texas Instruments, designed for RS422 and RS423 serial communication protocols. This component functions as a 0/4 receiver in 16-SOIC surface mount packaging. The AM26C32CNSR-P is classified as an obsolete product, which necessitates identification of active equivalent parts for ongoing design support and procurement continuity. Obsolete status indicates the manufacturer has discontinued production, making substitute parts essential for system maintenance, repairs, and new production runs requiring compatible functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AM26C32CNSR-P is determined by strict equivalence across the following critical parameters:

Protocol Compatibility: Both the main part and substitute must support RS422 and RS423 serial communication standards.

Receiver Configuration: The 0/4 receiver designation (zero drivers, four receivers) must be maintained in any substitute part.

Receiver Hysteresis: The 60 mV hysteresis specification must be preserved to ensure signal integrity and noise immunity characteristics remain unchanged.

Package and Pinout: The 16-SOIC surface mount package with 0.209" width and 5.30mm width specification ensures mechanical and electrical compatibility with existing PCB layouts.

Supply Voltage: The 4.5V to 5.5V supply voltage range must be supported by the substitute part.

RoHS Compliance: ROHS3 compliance status ensures environmental and regulatory alignment.

The AM26C32INSR qualifies as a direct substitute based on matching all these critical parameters. The primary distinction is product status: AM26C32INSR is active production, whereas AM26C32CNSR-P is obsolete.

Engineering Selection Recommendations

The AM26C32INSR is the direct substitute for the obsolete AM26C32CNSR-P. Selection of AM26C32INSR is based on the following engineering criteria:

Product Status: AM26C32INSR maintains active production status with Texas Instruments, ensuring long-term availability and supply chain continuity. The AM26C32CNSR-P obsolete status creates procurement risk and limits future sourcing options.

Functional Equivalence: Both parts maintain identical receiver configuration (0/4), protocol support (RS422/RS423), hysteresis specification (60 mV), and package form factor (16-SOIC). This ensures drop-in compatibility at the circuit level.

Compliance Alignment: Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, maintaining regulatory and environmental standards.

Temperature Range Expansion: The AM26C32INSR supports an extended operating temperature range of -40°C to 85°C compared to the AM26C32CNSR-P range of 0°C to 70°C. This expanded range provides additional operational flexibility for applications requiring wider temperature performance.

Supply Chain Availability: AM26C32INSR inventory levels (4688 pieces) exceed AM26C32CNSR-P availability (923 pieces), supporting immediate procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can AM26C32INSR be used as a direct replacement for AM26C32CNSR-P in existing designs?

A: Yes. Both parts share identical receiver configuration, protocol support, hysteresis specification, and 16-SOIC package form factor. No circuit modifications are required for substitution.

Q: What is the significance of the extended temperature range in AM26C32INSR?

A: The AM26C32INSR operates from -40°C to 85°C, compared to the AM26C32CNSR-P range of 0°C to 70°C. This extended range accommodates applications requiring operation in wider environmental conditions. For designs operating within 0°C to 70°C, both parts perform identically.

Q: Are there packaging differences between these parts?

A: No. Both parts use identical 16-SOIC surface mount packaging with 0.209" width and 5.30mm width specification. PCB layouts and footprints are fully compatible.

Q: Why is AM26C32CNSR-P classified as obsolete?

A: Obsolete status indicates Texas Instruments has discontinued production of this specific part number. The AM26C32INSR represents the active production equivalent with identical electrical and mechanical specifications.

Q: What compliance certifications apply to both parts?

A: Both AM26C32CNSR-P and AM26C32INSR are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. AM26C32INSR additionally carries REACH Unaffected status and EAR99 ECCN classification.

Q: Is the 10 Mbps data rate specification maintained in the substitute part?

A: The AM26C32INSR maintains full RS422 and RS423 protocol support. While the 10 Mbps data rate is specified for the AM26C32CNSR-P, both parts are functionally equivalent for serial communication applications within this performance envelope.
