Substitute Part Grouping Explanation

Substitution eligibility for the TS-701-HT-8H is determined by the following critical parameters:

Current Rating: 8A (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)

Substitute parts must meet all seven criteria above. Parts are grouped into two categories: parametric equivalents (identical electrical and mechanical specifications) and similar alternatives (minor voltage deviations acceptable for specific applications).

Engineering Selection Recommendations

Parametric Equivalents (Recommended Primary Substitutes)

The following parts are parametric equivalents with identical electrical and mechanical specifications to the TS-701-HT-8H:

TS-701-HT-8K (SCHURTER Inc., Obsolete status)
1140-G111-P1M1-8A (E-T-A, Active status)
1140-G151-P7M1-8A (E-T-A, Active status)
127-P10-H-KF-050022-8A (E-T-A, Active status)
127-P10-H-KF-8A (E-T-A, Active status)
1410-G110-P2F1-S01-8A (E-T-A, Active status)
1410-G111-P2F1-S01-385803-8A (E-T-A, Active status)
1410-G111-P2F1-S01-8A (E-T-A, Active status)
2-5000-P10-H-8A (E-T-A, Active status)

All parametric equivalents carry active product status except TS-701-HT-8K. E-T-A manufactured parts hold certifications including CSA C22.2 No 235, IEC 60934, and UL1077. All are ROHS3 compliant or RoHS compliant.

Similar Alternative (Voltage Deviation)

4404.0021 (SCHURTER Inc., Active status): Rated 240V AC / 48V DC. This part deviates from the specified 250V AC / 50V DC ratings and is suitable only for applications where lower voltage ratings are acceptable.

Frequently Asked Questions (FAQ)

Q: Can I use 4404.0021 as a direct replacement for TS-701-HT-8H?

A: No. The 4404.0021 is rated 240V AC / 48V DC, while the TS-701-HT-8H is rated 250V AC / 50V DC. Use 4404.0021 only if your application operates at or below 240V AC and 48V DC.

Q: What is the difference between TS-701-HT-8K and the parametric equivalents from E-T-A?

A: TS-701-HT-8K is electrically and mechanically identical to TS-701-HT-8H but is also obsolete. E-T-A equivalents (1140 series, 127 series, 1410 series, 2-5000 series) provide the same specifications with active product status and broader certification coverage.

Q: Are all parametric equivalents interchangeable?

A: Yes. All parametric equivalents meet the identical electrical specifications (8A, 250V AC, 50V DC) and mechanical requirements (panel mount, push-to-reset, single pole, thermal breaker). Physical form factor and mounting dimensions are consistent across all listed equivalents.

Q: What certifications apply to these circuit breakers?

A: SCHURTER parts carry ROHS3 compliance. E-T-A parts carry ROHS3 or RoHS compliance and hold approvals per CSA C22.2 No 235, IEC 60934, UL1077, and GB 17701 (where applicable).

Q: Does packaging type affect substitution eligibility?

A: No. Packaging (Box, Bulk) does not affect electrical or mechanical compatibility. Select based on procurement requirements and inventory management.

Q: Why is TS-701-HT-8H obsolete while equivalents remain active?

A: TS-701-HT-8H has been discontinued by SCHURTER Inc. Parametric equivalents from E-T-A and the TS-701-HT-8K variant remain in active production, ensuring continued availability for applications requiring 8A thermal circuit protection at 250V AC / 50V DC.
