Substitute Part Grouping Explanation
Substitution for the TS-709-15 is determined by strict equivalence across the following electrical and mechanical parameters:
- Current Rating: 15A (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 are grouped into two categories:
Parametric Equivalents (Full Electrical Match): Parts meeting all seven electrical and mechanical parameters above. These parts are direct functional replacements with identical electrical performance and physical mounting characteristics.
Similar Alternatives (Partial Parameter Match): Parts meeting the core functional requirements but with variations in voltage ratings or other secondary parameters. These require application-level verification before deployment.

Engineering Selection Recommendations
Primary Substitutes (Parametric Equivalents):
The E-T-A 1140 series and 127 series parts provide full electrical and mechanical equivalence to the TS-709-15. All eight parametric equivalent parts (1140-E211-P1M1-15A, 1140-E211-P9M1-15A, 1140-G111-P1M1-15A, 1140-G151-P7M1-15A, 127-P10-H-KF-050022-15A, 127-P10-H-KF-15A, 127-P11-H-KF-15A) maintain identical current, voltage, and functional specifications. All are active products with CSA C22.2 No 235, IEC 60934, and UL1077 certifications, meeting or exceeding the original TS-709-15 compliance profile. Inventory availability ranges from 604 to 1248 units across these options.
Secondary Alternatives (Partial Parameter Match):
The SCHURTER 4404.0028 maintains identical current rating, mounting, and actuation but operates at 240V AC and 48V DC, representing a 10V AC and 2V DC reduction from the original specification. This part is suitable only for applications where the lower voltage ratings are acceptable. The Carling Technologies CMB-153-11DNN-B-A maintains 250V AC but operates at 32V DC, an 18V DC reduction. This part is suitable only for applications where the reduced DC voltage rating is acceptable.
Compliance Considerations:
All substitute parts carry ROHS3 compliance and REACH unaffected status, matching the original part's environmental compliance profile. Approval agencies vary slightly; E-T-A parts include GB 17701 certification in addition to CSA and UL standards, providing broader international recognition.
Frequently Asked Questions (FAQ)
Q: Can the E-T-A 1140-G111-P1M1-15A directly replace the TS-709-15?
A: Yes. The 1140-G111-P1M1-15A meets all seven substitution criteria: 15A current rating, 250V AC, 50V DC, thermal breaker type, panel mount configuration, push-to-reset actuation, and single-pole design. It is an active product with equivalent certifications.
Q: What is the difference between the E-T-A 127 series and 1140 series substitutes?
A: Both series provide identical electrical specifications (15A, 250V AC, 50V DC). The difference lies in series designation and internal design architecture. Both are functionally equivalent for the TS-709-15 application.
Q: Can I use the SCHURTER 4404.0028 as a substitute?
A: The 4404.0028 is suitable only if your application operates at 240V AC and 48V DC or lower. It does not meet the full 250V AC and 50V DC specification of the original TS-709-15. Verify your system voltage requirements before selection.
Q: Can I use the Carling Technologies CMB-153-11DNN-B-A?
A: The CMB-153-11DNN-B-A is suitable only if your application operates at 32V DC or lower. It does not meet the full 50V DC specification of the original TS-709-15. Verify your system voltage requirements before selection.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All listed substitute parts carry ROHS3 compliance and REACH unaffected status, matching the environmental compliance of the original TS-709-15.
Q: Which substitute has the highest inventory availability?
A: The E-T-A 1140-G111-P1M1-15A offers the highest inventory with 1248 units in stock among the parametric equivalents.
Q: Do the E-T-A substitutes carry UL1077 certification?
A: Yes. All E-T-A substitute parts carry UL1077 certification, meeting the original TS-709-15 approval requirement. E-T-A parts additionally carry CSA C22.2 No 235 and IEC 60934 certifications.
