Key Parameters

Substitute Part Grouping Explanation

Substitution of the AM26LS32ACNSRG4 is determined by strict equivalence across the following critical parameters:

• Protocol compatibility: RS422 and RS423 support
• Receiver configuration: 0/4 (zero drivers, four receivers)
• Receiver hysteresis: 50 mV
• Supply voltage range: 4.75V ~ 5.25V
• Operating temperature range: 0°C ~ 70°C
• Package type: 16-SOIC surface mount
• Regulatory compliance: ROHS3, REACH Unaffected, EAR99 classification

The AM26LS32ACNSR qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is product status and packaging availability, with the substitute part remaining in active production and available in standard cut tape and Digi-Reel formats.

Parameter Comparison

Engineering Selection Recommendations

The AM26LS32ACNSR is the direct substitute for the discontinued AM26LS32ACNSRG4. Both parts share identical electrical specifications, package configuration, and regulatory compliance certifications. The substitute part maintains active production status and is available through standard distribution channels in cut tape and Digi-Reel packaging formats, ensuring supply chain continuity for new designs and production replenishment.

Selection of the AM26LS32ACNSR eliminates obsolescence risk while maintaining full functional and mechanical compatibility with existing circuit designs. Both parts carry ROHS3 compliance and REACH unaffected status, supporting regulatory requirements for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can the AM26LS32ACNSR be used as a direct replacement for the AM26LS32ACNSRG4?

A: Yes. Both parts are electrically and mechanically identical, with matching receiver configurations (0/4), protocol support (RS422/RS423), hysteresis (50 mV), supply voltage (4.75V ~ 5.25V), operating temperature range (0°C ~ 70°C), and 16-SOIC package specifications. The primary difference is product status and packaging availability.

Q: What is the difference between the two part numbers?

A: The AM26LS32ACNSRG4 is discontinued at DiGi Electronics, while the AM26LS32ACNSR remains in active production. The suffix variation reflects packaging and distribution channel differences, with the substitute available in standard cut tape and Digi-Reel formats.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical ROHS3 compliance, REACH unaffected status, EAR99 ECCN classification, and HTSUS code 8542.39.0001. Regulatory requirements are fully satisfied by either part.

Q: What is the receiver hysteresis specification, and why is it important?

A: Both parts specify 50 mV receiver hysteresis, which defines the voltage difference between the rising and falling threshold levels for signal detection in RS422/RS423 communication. This specification ensures stable signal interpretation across the operating temperature range.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. Identical package type (16-SOIC), pin configuration, and electrical specifications ensure direct PCB compatibility without design modifications.
