Substitute Part Grouping Explanation

Substitution for the TS-701-HT-15 is determined by strict equivalence across the following critical parameters:

Parametric Equivalents (Full Compatibility): Parts matching all key electrical and mechanical specifications—15A current rating, 250V AC / 50V DC voltage ratings, single-pole thermal breaker type, push-to-reset actuation, and panel mount configuration—are classified as parametric equivalents. These parts are direct replacements with no derating or application modification required.

Similar Substitutes (Voltage Derating): Parts with identical current rating (15A), mounting type, breaker type, and actuation but reduced DC voltage ratings (48V DC or 32V DC) are classified as similar substitutes. These parts require application review to confirm DC voltage compatibility within the lower rating.

Active vs. Obsolete Status: Parametric equivalent parts from E-T-A (1140 series and 127 series) and the SCHURTER 4404.0028 are all active products, providing long-term availability. Carling Technologies CLB series parts are active alternatives with voltage derating considerations.

Engineering Selection Recommendations

Parametric Equivalent Selection: For direct replacement without application modification, select from the E-T-A 1140 series (1140-E211-P1M1-15A, 1140-E211-P9M1-15A, 1140-G111-P1M1-15A, 1140-G151-P7M1-15A) or E-T-A 127 series (127-P10-H-KF-050022-15A, 127-P10-H-KF-15A). All maintain the 250V AC / 50V DC rating and carry CSA C22.2 No 235 and IEC 60934 certifications, ensuring regulatory compliance across North American and international markets.

SCHURTER Active Alternative: The SCHURTER 4404.0028 provides continuity within the SCHURTER product line but operates at reduced voltage ratings (240V AC / 48V DC). This part is suitable only if the application operates within these lower voltage specifications.

Carling Technologies Alternatives: The CLB-153-11ANN-B-A and CLB-153-11ANN-R-A maintain 250V AC compatibility but are rated for 32V DC maximum. These parts are appropriate only for applications with DC voltage requirements not exceeding 32V. Both carry UL1077 and UL1500 certifications.

Availability and Long-Term Support: All recommended parametric equivalents are active products with established inventory levels, ensuring sustained availability for production and field replacement requirements.

Frequently Asked Questions (FAQ)

Q: Can I use the SCHURTER 4404.0028 as a direct replacement for the TS-701-HT-15?

A: The 4404.0028 is a similar substitute with voltage derating. It maintains the 15A current rating and thermal breaker type but operates at 240V AC / 48V DC versus the original 250V AC / 50V DC. Use this part only if your application operates within the lower voltage specifications.

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

A: Both series provide parametric equivalence to the TS-701-HT-15 with identical electrical ratings (15A, 250V AC, 50V DC) and thermal breaker configuration. The primary difference is the series designation and internal design. Both are active products with full regulatory compliance.

Q: Are the Carling Technologies CLB parts suitable replacements?

A: The CLB-153-11ANN-B-A and CLB-153-11ANN-R-A are similar substitutes with DC voltage derating (32V DC maximum versus 50V DC). They maintain 250V AC and 15A ratings. These parts are suitable only if your application does not require DC voltage operation above 32V.

Q: What certifications should I verify for my application?

A: The TS-701-HT-15 carries CSA C22.2 and UL1077 certifications. All E-T-A parametric equivalents maintain CSA C22.2 No 235 and IEC 60934 compliance. Carling Technologies alternatives add UL1500 certification. Confirm that your application requirements align with the certification standards of your selected substitute.

Q: Does packaging affect substitution compatibility?

A: Packaging (bulk, box, or reel) does not affect electrical or mechanical compatibility. Select based on your procurement and inventory management requirements.

Q: Can I mix different substitute parts in the same application?

A: All parametric equivalent parts (E-T-A 1140 and 127 series) are interchangeable within the same circuit. Similar substitutes with voltage derating (SCHURTER 4404.0028, Carling CLB series) must be evaluated individually for your specific voltage environment.
