Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM26C32MDREP is determined by the following critical parameters:

• Protocol Compatibility: RS422 and RS423 support
• Receiver Configuration: 0/4 receiver architecture
• Receiver Hysteresis: 60 mV threshold
• Package Type: 16-SOIC form factor
• Supply Voltage Range: 4.5V to 5.5V operation
• Surface Mount Compatibility: SOIC package mounting

Substitute parts must maintain these core electrical and mechanical specifications. Variations in operating temperature range, data rate, or supply voltage specifications indicate design trade-offs that may affect system performance in specific applications but do not preclude functional substitution within defined operating conditions.

Parameter Comparison

Engineering Selection Recommendations

DS26C32ATM/NOPB and DS26C32ATMX/NOPB are direct functional equivalents from Texas Instruments with identical electrical specifications to the AM26C32MDREP. Both maintain RS422/RS423 protocol support, 60 mV receiver hysteresis, and 4.5V to 5.5V supply voltage operation. The primary difference is packaging format: DS26C32ATM/NOPB is supplied in Tube packaging, while DS26C32ATMX/NOPB is supplied in Cut Tape (CT) & Digi-Reel format. DS26C32ATMX/NOPB offers the highest inventory availability at 22,854 units. Operating temperature range is reduced to -40°C to 85°C compared to the AM26C32MDREP's -55°C to 125°C specification.

ST26C32ABDR from STMicroelectronics maintains full electrical compatibility with identical supply voltage, receiver hysteresis, and protocol support. This part is supplied in Cut Tape (CT) & Digi-Reel packaging with 87,600 units in stock. Operating temperature range is -40°C to 85°C. Data rate specification of 20 Mbps is provided for this part.

SP26LV432CN-L from MaxLinear, Inc. is functionally compatible but operates at 3.3V supply voltage rather than 4.5V to 5.5V, and has a narrower operating temperature range of 0°C to 70°C. This part supports RS422 and RS485 protocols. Product status is Last Time Buy, indicating limited future availability. Moisture Sensitivity Level is MSL 2 (1 Year) versus MSL 1 (Unlimited) for other options. This part is suitable only for applications with 3.3V power supply requirements.

For applications requiring the full -55°C to 125°C operating temperature range of the AM26C32MDREP, no direct substitute maintains this specification. Selection of alternative parts requires confirmation that the reduced temperature range (-40°C to 85°C) is acceptable for the target application.

Frequently Asked Questions (FAQ)

Q: Can DS26C32ATM/NOPB directly replace AM26C32MDREP in all applications?

A: DS26C32ATM/NOPB is electrically equivalent for RS422/RS423 receiver functionality. The primary consideration is operating temperature range: DS26C32ATM/NOPB operates from -40°C to 85°C versus AM26C32MDREP's -55°C to 125°C. Substitution is valid only if the application's operating environment falls within -40°C to 85°C.

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

A: Both parts are electrically identical. The difference is packaging format: DS26C32ATM/NOPB is supplied in Tube packaging, while DS26C32ATMX/NOPB is supplied in Cut Tape (CT) & Digi-Reel format. DS26C32ATMX/NOPB has significantly higher inventory availability (22,854 units versus 1,312 units).

Q: Is ST26C32ABDR compatible with AM26C32MDREP?

A: ST26C32ABDR from STMicroelectronics maintains identical receiver configuration, protocol support, and supply voltage specifications. Operating temperature range is -40°C to 85°C. The part is pin-compatible in 16-SOIC packaging and suitable for substitution within the specified temperature range.

Q: Why is SP26LV432CN-L listed as a substitute if it operates at 3.3V?

A: SP26LV432CN-L is functionally equivalent in receiver architecture and protocol support but requires 3.3V supply voltage instead of 4.5V to 5.5V. This part is suitable only for applications designed for 3.3V operation. Additionally, SP26LV432CN-L has Last Time Buy status, indicating limited future availability.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts maintain ROHS3 compliance and REACH Unaffected status, consistent with the AM26C32MDREP.

Q: What is the significance of Moisture Sensitivity Level (MSL) differences?

A: AM26C32MDREP, DS26C32ATM/NOPB, DS26C32ATMX/NOPB, and ST26C32ABDR all have MSL 1 (Unlimited), indicating no moisture sensitivity constraints. SP26LV432CN-L has MSL 2 (1 Year), requiring storage in controlled humidity conditions and limiting shelf life to one year from manufacturing date.
