TS-701-HT-10 Equivalent & Substitute Parts

Part Overview

The TS-701-HT-10 is a thermal circuit breaker manufactured by SCHURTER Inc., rated for 10A at 250V AC / 50V DC with push-to-reset panel mount actuation. This component is classified as obsolete, making equivalent substitutes necessary for ongoing system maintenance and new designs requiring this functional specification.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters:

Current Rating: 10A
Voltage Rating - AC: 250V
Voltage Rating - DC: 50V
Breaker Type: Thermal
Mounting Type: Panel Mount
Actuator Type: Push to Reset
Number of Poles: 1
RoHS Status: ROHS3 Compliant

Substitute parts are grouped into two categories:

Parametric Equivalents maintain all critical electrical and mechanical parameters identical to the TS-701-HT-10. These parts are direct functional replacements with no derating or operational limitations.

Direct Manufacturer Equivalent (TE Connectivity W58-XC4C12A-10) meets all electrical specifications and mounting requirements with active product status.

Similar Parts (Carling Technologies CLB series) match current, voltage AC, mounting, and actuation specifications but operate at reduced DC voltage (32V versus 50V). These are suitable only where DC voltage requirements do not exceed 32V.

Engineering Selection Recommendations

Primary Recommendation: W58-XC4C12A-10 (TE Connectivity)

This part provides full parametric equivalence with active product status, ensuring long-term availability and supply chain stability. It carries ROHS3 compliance and is packaged in trays for standard procurement workflows.

Secondary Recommendations: E-T-A Series (1140 and 127 families)

The E-T-A 1140-F111-P1M1-10A, 1140-F114-P1M1-10A, 1140-G111-P1M1-10A, 1140-G151-P7M1-10A, 127-F11-P10-H-KF-10A, and 127-P10-H-KF-050022-10A all provide complete electrical and mechanical equivalence with active product status. These parts carry additional international certifications (CSA C22.2 No 235, IEC 60934, GB 17701) and are suitable for applications requiring expanded regulatory compliance.

Alternative: TS-709-10 (SCHURTER Inc.)

This SCHURTER part maintains full parametric equivalence but carries obsolete product status. Selection is appropriate only where existing supply inventory is available or where SCHURTER-specific design requirements exist.

Conditional Use: Carling Technologies CLB Series (CLB-103-11ANN-B-A, CLB-103-11ANN-R-A)

These parts are suitable only for applications where DC voltage requirements do not exceed 32V. The reduced DC voltage rating (32V versus 50V) represents a derating from the original specification. These parts carry expanded certifications (CE, cUL, TUV, UL1077, UL1500) and active product status.

Frequently Asked Questions (FAQ)

Q: Can I use the Carling Technologies CLB-103-11ANN-B-A as a direct replacement for the TS-701-HT-10?

A: The CLB-103-11ANN-B-A matches the AC voltage (250V), current (10A), mounting type (panel mount), and actuation (push to reset) specifications. However, its DC voltage rating is 32V compared to the TS-701-HT-10's 50V DC rating. Use this part only if your application's DC voltage does not exceed 32V.

Q: What is the difference between the E-T-A 1140 and 127 series parts?

A: Both series meet the electrical and mechanical requirements of the TS-701-HT-10. The 127 series carries additional international certifications including GB 17701. Selection between them depends on regulatory requirements specific to your application region.

Q: Why is the TS-709-10 listed as a substitute if it is also obsolete?

A: The TS-709-10 provides complete parametric equivalence and may be available through existing inventory channels. It is listed for applications where SCHURTER continuity is required or where supply exists. For new designs, active-status alternatives are preferred.

Q: Are there packaging differences between substitute parts?

A: Yes. The TS-701-HT-10 is packaged as individual units (-). The TS-709-10 is supplied in bulk packaging. The W58-XC4C12A-10 is supplied in trays. E-T-A parts are supplied in bulk. Carling Technologies parts are supplied in bulk. Confirm packaging compatibility with your procurement and assembly processes.

Q: What certifications should I verify for my application?

A: The TS-701-HT-10 carries CSA C22.2 and UL1077 certifications (per TS-709-10 data). E-T-A parts carry CSA C22.2 No 235, IEC 60934, and UL1077. Carling Technologies parts carry CE, cUL, TUV, UL1077, and UL1500. Confirm that the selected substitute meets your application's regulatory requirements.

Q: Is the TS-701-HT-10 truly obsolete, or can I still source it?

A: The TS-701-HT-10 is classified as obsolete by the manufacturer. Current inventory of 958 pieces is available through existing stock channels, but long-term availability is not assured. For new designs or long-term production, selection of an active-status substitute is recommended.
