Substitute Part Grouping Explanation

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

Current Rating: 12A (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 meet these criteria. Parts are grouped by manufacturer and product status to facilitate selection based on availability and compliance requirements.

Engineering Selection Recommendations

Parametric Equivalents (Exact Electrical Match):

The following parts are parametric equivalents with identical electrical and mechanical specifications to TS-701-HT-12-K:

TS-701-HT-12H (SCHURTER Inc., Obsolete)
1140-F111-P1M1-12A (E-T-A, Active)
1140-G111-P1M1-12A (E-T-A, Active)
1140-G151-P7M1-12A (E-T-A, Active)
127-P10-H-KF-12A (E-T-A, Active)
2-5000-P10-H-12A (E-T-A, Active)
CTB-B-B-12 (Carling Technologies, Active)

All parametric equivalents carry ROHS3 compliance and are certified to IEC 60934 and UL1077 standards. E-T-A and Carling Technologies parts are currently in active production status, ensuring long-term availability.

Near-Equivalent (Voltage Variance):

4404.0023 (SCHURTER Inc., Active) operates at 240V AC and 48V DC, representing a minor voltage reduction from the original specification. This part is suitable only where the lower voltage ratings are acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can I use 4404.0023 as a direct substitute for TS-701-HT-12-K?

A: No. The 4404.0023 has voltage ratings of 240V AC and 48V DC, compared to the TS-701-HT-12-K specification of 250V AC and 50V DC. Use only if your application operates within the lower voltage envelope.

Q: Which substitute parts are recommended for new designs?

A: Select from active-status parts: 1140-F111-P1M1-12A, 1140-G111-P1M1-12A, 1140-G151-P7M1-12A, 127-P10-H-KF-12A, 2-5000-P10-H-12A, or CTB-B-B-12. All meet identical electrical specifications and carry current manufacturing support.

Q: Are all substitute parts panel-mount compatible with existing installations?

A: Yes. All listed substitutes share identical mounting type (panel mount) and actuator type (push to reset), ensuring mechanical compatibility with existing panel cutouts and control circuits.

Q: What certifications apply to substitute parts?

A: E-T-A parts carry CSA C22.2 No 235, IEC 60934, and UL1077 certifications. Carling Technologies CTB-B-B-12 carries CE, cUL, UL1077, and VDE certifications. All are ROHS3 compliant.

Q: Does packaging type affect substitution eligibility?

A: No. Packaging (bulk or box) does not affect electrical or mechanical compatibility. Select based on procurement quantity requirements and inventory availability.
