Substitute Part Grouping Explanation

Substitution of the TPSMC85CA-VR is determined by strict equivalence in the following critical parameters:

Mechanical Compatibility:

• Package type: DO-214AB (SMC)
• Mounting type: Surface Mount
• Bidirectional channels: 1

Electrical Performance:

• Component type: Zener TVS diode
• Power rating: 1500W peak pulse (1.5kW)
• Applications: General Purpose

Compliance & Certification:

• RoHS3 compliance
• REACH unaffected status
• Automotive grade classification

The substitute part 1.5SMC100CA_R1_00001 meets all mechanical and electrical equivalence criteria. Voltage and current parameters are provided for the substitute to enable circuit-level verification by the design engineer.

Parameter Comparison

Engineering Selection Recommendations

Both the TPSMC85CA-VR and 1.5SMC100CA_R1_00001 are active production components with ROHS3 compliance and REACH unaffected status. Both are automotive-grade TVS diodes in identical DO-214AB surface mount packages with equivalent 1500W peak pulse power ratings.

The TPSMC85CA-VR operates across a wider temperature range (-65°C to 150°C) compared to the substitute part (-55°C to 150°C). Selection between these components should be based on the specific operating temperature requirements of the application and circuit-level voltage/current specifications.

Frequently Asked Questions (FAQ)

Q: Can the 1.5SMC100CA_R1_00001 directly replace the TPSMC85CA-VR in existing designs?

A: Direct replacement is possible from a mechanical and package perspective, as both components use the DO-214AB (SMC) surface mount package. However, circuit-level verification is required to confirm that the voltage and current parameters of the substitute part (137V clamping, 11A peak pulse) are compatible with the application requirements.

Q: What is the difference in operating temperature range between these parts?

A: The TPSMC85CA-VR operates from -65°C to 150°C, while the 1.5SMC100CA_R1_00001 operates from -55°C to 150°C. Applications requiring operation below -55°C must use the TPSMC85CA-VR.

Q: Are both parts automotive qualified?

A: The TPSMC85CA-VR carries AEC-Q101 automotive qualification. The 1.5SMC100CA_R1_00001 is classified as automotive grade. Compliance requirements for specific automotive applications should be verified against design specifications.

Q: Do both parts meet RoHS and REACH requirements?

A: Yes. Both the TPSMC85CA-VR and 1.5SMC100CA_R1_00001 are ROHS3 compliant and REACH unaffected.

Q: What packaging options are available?

A: Both parts are supplied in Tape & Reel (TR) packaging for surface mount assembly. The component package is DO-214AB (SMC).
