Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM26C32ID is determined by the following critical parameters:

• Protocol support: RS422 and/or RS423 compatibility
• Receiver configuration: 0/4 (4 receivers, no drivers)
• Receiver hysteresis: 60 mV
• Supply voltage range: 4.5V ~ 5.5V
• Operating temperature range: -40°C ~ 85°C
• Package type: 16-SOIC surface mount
• RoHS3 compliance

Substitute parts are grouped into two categories:

MFR Recommended Substitutes: Parts from the same manufacturer (Texas Instruments) with identical electrical specifications and package compatibility. These include AM26C32IDR, DS26C32ATM/NOPB, and DS26C32ATMX/NOPB.

Parametric Equivalents: Parts from alternative manufacturers (Texas Instruments DS34C86TM/NOPB and STMicroelectronics ST26C32ABDR) that meet the core electrical and mechanical requirements. The SP26LV432CN-L from MaxLinear operates at different voltage and temperature ranges and is included as a reference for specialized applications only.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Direct Replacement):

AM26C32IDR is the recommended first choice. It is manufactured by Texas Instruments with identical electrical specifications and Active product status, ensuring long-term availability and supply chain stability. The only difference is packaging format (Cut Tape & Digi-Reel vs. Tube), which does not affect electrical performance.

DS26C32ATMX/NOPB is the second recommended option. It maintains all critical electrical parameters and offers the highest inventory availability (22854 Pcs) among active parts. This part is suitable for high-volume procurement.

Secondary Substitutes (Parametric Equivalents):

DS26C32ATM/NOPB and DS34C86TM/NOPB are functionally equivalent alternatives from Texas Instruments. Both maintain identical electrical specifications and operating ranges. Selection between these parts should be based on inventory availability and packaging requirements.

ST26C32ABDR from STMicroelectronics is a parametric equivalent with the highest inventory level (87600 Pcs). It meets all electrical and mechanical requirements and carries Active product status. The 16-SO package designation is mechanically compatible with 16-SOIC footprints.

Not Recommended for Direct Substitution:

SP26LV432CN-L operates at 3.3V supply voltage and a reduced temperature range (0°C ~ 70°C), making it unsuitable for applications requiring the full -40°C ~ 85°C operating range or 4.5V ~ 5.5V supply voltage. This part is listed for reference only in specialized low-voltage applications.

Frequently Asked Questions (FAQ)

Q: Can AM26C32IDR be used as a direct replacement for AM26C32ID?

A: Yes. Both parts are manufactured by Texas Instruments with identical electrical specifications, receiver configuration, protocol support, and package dimensions. The difference in packaging format (Cut Tape & Digi-Reel vs. Tube) does not affect electrical performance or PCB compatibility.

Q: What is the difference between DS26C32ATM/NOPB and DS26C32ATMX/NOPB?

A: Both parts are electrically identical with the same specifications, supply voltage, temperature range, and package type. The primary difference is inventory availability. DS26C32ATMX/NOPB has higher stock levels (22854 Pcs vs. 1312 Pcs), making it preferable for procurement planning.

Q: Is ST26C32ABDR compatible with the AM26C32ID footprint?

A: Yes. The ST26C32ABDR uses a 16-SO package, which is mechanically compatible with 16-SOIC footprints. All electrical specifications match the AM26C32ID requirements. The higher inventory availability (87600 Pcs) makes this part suitable for volume production.

Q: Why is SP26LV432CN-L not recommended as a substitute?

A: The SP26LV432CN-L operates at 3.3V supply voltage and a restricted temperature range of 0°C ~ 70°C, compared to the AM26C32ID's 4.5V ~ 5.5V and -40°C ~ 85°C specifications. It is not suitable for applications requiring the full operating range of the original part.

Q: What should I consider when selecting between multiple substitute parts?

A: Selection should prioritize product status (Active parts are preferred over Last Time Buy), inventory availability for your procurement volume, packaging format compatibility with your assembly process, and supply chain reliability. All recommended substitutes maintain identical electrical specifications and package compatibility.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry RoHS3 compliance certification, matching the environmental and regulatory requirements of the AM26C32ID.
