AM26C31CNSR Equivalent & Substitute Parts

Part Overview

The AM26C31CNSR is a 4/0 Driver interface IC manufactured by Texas Instruments in a 16-SOIC surface mount package. This component is classified as an active product with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same functional category, allowing for direct replacement in applications requiring 4/0 driver functionality with 4.5V to 5.5V supply voltage operation.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AM26C31CNSR are qualified based on the following criteria:

• Identical driver/receiver configuration (4/0)
• Matching supply voltage range (4.5V ~ 5.5V)
• Surface mount packaging with compatible pinout
• Active product status with current manufacturing support
• ROHS3 compliance and equivalent environmental certifications

The three identified substitutes (DS26C31TM/NOPB, DS26C31TMX/NOPB, and ST26C31BDR) meet these core electrical and mechanical requirements. Variations in operating temperature range and package width do not preclude substitution when the application environment falls within the substitute part's rated specifications.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain active product status with current manufacturing availability. DS26C31TM/NOPB and DS26C31TMX/NOPB are both Texas Instruments products with extended operating temperature ranges (-40°C to 85°C) compared to the AM26C31CNSR (0°C to 70°C), providing broader environmental coverage when required. Both DS26C31 variants feature narrower package widths (0.154" versus 0.209") and unlimited moisture sensitivity rating.

ST26C31BDR from STMicroelectronics provides equivalent electrical functionality with the same 4.5V to 5.5V supply voltage and 4/0 driver configuration. This part operates across the extended temperature range and features a narrower package profile. The ST26C31BDR carries a moisture sensitivity level of 3 (168 hours), which requires controlled storage conditions compared to the unlimited MSL rating of the primary part and other Texas Instruments substitutes.

Selection between substitutes should be based on application-specific requirements for operating temperature range, package space constraints, and moisture handling procedures during assembly and storage.

Frequently Asked Questions (FAQ)

Q: Can DS26C31TM/NOPB directly replace AM26C31CNSR in all applications?

A: DS26C31TM/NOPB meets the core electrical requirements (4/0 driver configuration, 4.5V to 5.5V supply voltage) and surface mount packaging compatibility. The extended operating temperature range (-40°C to 85°C) encompasses the AM26C31CNSR specification (0°C to 70°C). Package width differs (0.154" versus 0.209"), which may affect PCB layout compatibility. Verify pinout alignment and PCB footprint accommodation before implementation.

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

A: Both parts share identical electrical specifications, supply voltage range, operating temperature range, and moisture sensitivity rating. The primary distinction is packaging format: DS26C31TM/NOPB is supplied in Tube packaging, while DS26C31TMX/NOPB is supplied in Cut Tape (CT) & Digi-Reel® format. Electrical and mechanical compatibility are equivalent.

Q: Is ST26C31BDR suitable for applications requiring unlimited moisture sensitivity?

A: ST26C31BDR carries a moisture sensitivity level of 3 (168 hours), requiring controlled storage and handling procedures. Applications demanding unlimited MSL rating should prioritize AM26C31CNSR, DS26C31TM/NOPB, or DS26C31TMX/NOPB. Verify assembly and storage environment capabilities before selecting ST26C31BDR.

Q: Do all substitute parts maintain ROHS3 compliance?

A: All identified substitutes (DS26C31TM/NOPB, DS26C31TMX/NOPB, and ST26C31BDR) are ROHS3 compliant, matching the compliance status of the AM26C31CNSR. Environmental and regulatory requirements are maintained across all options.

Q: How do package width differences affect substitution?

A: The AM26C31CNSR features a 16-SOIC package with 0.209" width, while all three substitutes use 0.154" width packages. Narrower packages may require PCB footprint redesign or verification that existing footprints accommodate the smaller width. Pinout and lead spacing remain compatible within the 16-SOIC family. Confirm PCB layout compatibility before component selection.
