Substitute Part Grouping Explanation

Substitute parts are qualified based on the following critical parameters that must match the main part specification:

Current Rating: 25A (exact match required)
Voltage Rating - AC: 250V (exact match required)
Voltage Rating - DC: 50V (exact match required)
Breaker Type: Thermal (exact match required)
Mounting Type: Panel Mount (exact match required)
Actuator Type: Push to Reset (exact match required)
Number of Poles: 1 (exact match required)

All substitute parts listed below satisfy these mandatory parameters. Substitutes are grouped by manufacturer and series designation. Active product status substitutes are preferred for new designs, while obsolete equivalents maintain compatibility with legacy systems.

Engineering Selection Recommendations

For new designs, select from active product status substitutes. The W58-XB1A4A-25 from TE Connectivity Potter & Brumfield Relays offers active product status with established supply chain availability. E-T-A series substitutes (127, 157, and 2-5000 families) provide multiple active alternatives with established regulatory certifications including CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077.

For legacy system maintenance where the TS-701-HT-25P is no longer available, the TS-701-HT-25 provides direct compatibility as an obsolete equivalent from the same manufacturer and series. All listed substitutes maintain ROHS3 compliance and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can I substitute the TS-701-HT-25P with any of the listed parts?

A: Yes. All listed parts maintain identical electrical specifications (25A, 250V AC, 50V DC), breaker type (thermal), mounting configuration (panel mount), and actuation method (push to reset). Direct substitution is supported based on these matching parameters.

Q: What is the difference between TS-701-HT-25P and TS-701-HT-25?

A: Both parts are from SCHURTER Inc. TS series and share identical electrical and mechanical specifications. The primary difference is packaging: TS-701-HT-25P is packaged individually, while TS-701-HT-25 is supplied in bulk. Both are classified as obsolete.

Q: Should I prefer active or obsolete product status substitutes?

A: For new designs, select active product status parts to ensure long-term supply availability and support. Active substitutes include all E-T-A series parts (127, 157, 2-5000 families) and the W58-XB1A4A-25 from TE Connectivity. Obsolete equivalents are suitable only for legacy system maintenance where the original part is no longer available.

Q: Are there regulatory compliance differences between substitutes?

A: All substitutes maintain ROHS3 compliance. E-T-A series parts carry additional certifications: CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077. SCHURTER TS-701-HT-25 carries CSA C22.2 and UL1077 certifications. TE Connectivity W58-XB1A4A-25 carries ROHS3 compliance with MSL 1 (Unlimited) rating.

Q: What packaging options are available?

A: Substitutes are available in bulk and tray packaging. Packaging selection does not affect electrical or mechanical compatibility. Verify packaging requirements based on procurement and assembly processes.

Q: Can I use these substitutes in both AC and DC applications?

A: Yes. All parts are rated for 250V AC and 50V DC operation. Selection between AC and DC application depends on system requirements, not part compatibility.
