Substitute Part Grouping Explanation
Substitute parts for the TS-701-HT-8 are classified based on electrical parameter equivalence and mechanical compatibility. The primary substitution criteria are:
Electrical Parameters:
- Current Rating: 8A (exact match required)
- Voltage Rating - AC: 250V (exact match required)
- Voltage Rating - DC: 50V or lower (50V DC is maximum allowable)
- Breaker Type: Thermal (exact match required)
Mechanical Parameters:
- Mounting Type: Panel Mount (exact match required)
- Actuator Type: Push to Reset (exact match required)
- Number of Poles: 1 (exact match required)
Substitutes are grouped into two categories: parametric equivalents (identical electrical and mechanical specifications) and similar parts (matching core parameters with minor voltage deviations).

Engineering Selection Recommendations
Parametric Equivalents (Identical Specifications):
The following parts match all electrical and mechanical parameters of the TS-701-HT-8:
- TS-701-HT-8K (SCHURTER Inc., Obsolete) — Same series variant with identical ratings
- 1140-G111-P1M1-8A (E-T-A, Active) — Active product with CSA C22.2 No 235, IEC 60934, UL1077 certifications
- 1140-G151-P7M1-8A (E-T-A, Active) — Active product with CSA C22.2 No 235, IEC 60934, UL1077 certifications
- 127-P10-H-KF-050022-8A (E-T-A, Active) — Active product with CSA C22.2 No 235, GB 17701, IEC 60934, UL1077 certifications
- 127-P10-H-KF-8A (E-T-A, Active) — Active product with CSA C22.2 No 235, GB 17701, IEC 60934, UL1077 certifications
- 1410-G110-P2F1-S01-8A (E-T-A, Active) — Active product with CSA C22.2 No 235, IEC 60934, UL1077 certifications

For new designs and long-term availability, E-T-A parametric equivalents are preferred due to active product status and established regulatory certifications.
Similar Parts (Voltage Deviations):
- 4404.0021 (SCHURTER Inc., Active) — 240V AC / 48V DC variant. Suitable where system voltage is 240V AC or lower and DC voltage is 48V or lower
- CLB-083-11ANN-R-A (Carling Technologies, Active) — 250V AC / 32V DC variant. Suitable where system DC voltage is 32V or lower. Includes CE, cUL, TUV, UL1077, UL1500 certifications
Selection Criteria:
For direct replacement in existing systems rated 250V AC / 50V DC, select from parametric equivalents.

All listed substitutes maintain thermal breaker operation, 8A current rating, panel mount configuration, and push-to-reset actuation.
Frequently Asked Questions (FAQ)
Q: Can TS-701-HT-8K be used as a direct replacement for TS-701-HT-8?
A: Yes. TS-701-HT-8K is a parametric equivalent with identical electrical ratings (8A, 250V AC, 50V DC), mounting type (panel mount), and actuator type (push to reset). The difference is packaging: TS-701-HT-8 is supplied in standard packaging while TS-701-HT-8K is supplied in bulk packaging.
Q: Is 4404.0021 compatible with TS-701-HT-8?
A: 4404.0021 is compatible only in systems where the AC voltage is 240V or lower and DC voltage is 48V or lower. It shares the same 8A current rating, panel mount configuration, and push-to-reset actuation. However, the voltage ratings are reduced compared to the original part.
Q: What is the difference between E-T-A parametric equivalents?
A: All E-T-A parametric equivalents (1140 series, 127 series, 1410 series) provide identical electrical and mechanical specifications to TS-701-HT-8. Differences exist in series designation and internal design. All are active products with established regulatory approvals. Selection among these variants depends on availability, lead time, and specific application requirements.
Q: Can CLB-083-11ANN-R-A replace TS-701-HT-8 in all applications?
A: CLB-083-11ANN-R-A is suitable only for applications where the DC voltage requirement is 32V or lower. It maintains the 8A current rating, 250V AC rating, panel mount configuration, and push-to-reset actuation. Applications requiring 50V DC operation must use parametric equivalents.
Q: Why are some substitutes listed as obsolete?
A: TS-701-HT-8 and TS-701-HT-8K are both obsolete products. For new designs and systems requiring long-term component availability, active product substitutes from E-T-A (1140, 127, and 1410 series) are recommended.
Q: Are all listed substitutes RoHS compliant?
A: All listed substitutes are RoHS compliant. TS-701-HT-8, TS-701-HT-8K, 4404.0021, CLB-083-11ANN-R-A, and E-T-A 1140 and 127 series parts are ROHS3 compliant. E-T-A 1410 series parts are RoHS compliant. All are REACH unaffected.
