Substitute Part Grouping Explanation

Substitute parts for the TS-709-5H are grouped into two categories based on electrical parameter alignment:

Parametric Equivalents (Full Match): Parts matching all critical electrical parameters—5A current rating, 250V AC, 50V DC, single-pole thermal operation, and push-to-reset actuation. These include E-T-A series 1140, 127, and 1410-G1 variants. All parametric equivalents maintain identical voltage and current specifications, ensuring direct functional replacement in existing circuits.

Functional Substitutes (Voltage Variance): The SCHURTER 4404.0025 operates at 240V AC and 48V DC, representing a near-equivalent with marginally reduced voltage ratings. This part is suitable for applications where the lower voltage specification does not compromise system requirements.

Critical Parameters for Substitution:

Current Rating: 5A (mandatory match)
Voltage Rating - AC: 250V or 240V (acceptable variance)
Voltage Rating - DC: 50V or 48V (acceptable variance)
Breaker Type: Thermal (mandatory match)
Mounting Type: Panel Mount (mandatory match)
Actuator Type: Push to Reset (mandatory match)
Number of Poles: 1 (mandatory match)

Engineering Selection Recommendations

Primary Substitutes (Parametric Equivalents): E-T-A series parts 1140-E211-P1M1-5A, 1140-G111-P1M1-5A, 1140-G151-P7M1-5A, 127-P10-H-KF-5A, 127-P10-H-KF-D91-5A, 1410-G110-P2F1-S01-5A, 1410-G111-P2F1-S01-5A, and 1410-G114-P3F1-S01-5A are all active products with full electrical parameter alignment to the TS-709-5H. These parts carry CSA C22.2 No 235, IEC 60934, and UL1077 certifications, meeting or exceeding the original part's approval standards. Inventory availability ranges from 668 to 2100 units across variants.

Secondary Substitute (Voltage Variance): SCHURTER 4404.0025 is an active product with 240V AC and 48V DC ratings, representing a 10V reduction in AC specification and 2V reduction in DC specification. This part is suitable for applications where system voltage margins accommodate the lower ratings. The 4404.0025 carries expanded certifications including CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077.

Compliance Alignment: All substitute parts maintain ROHS3 compliance and REACH unaffected status, consistent with the original TS-709-5H specification. Selection should prioritize active-status parts to ensure long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 4404.0025 directly replace the TS-709-5H in all applications?

A: The 4404.0025 is functionally compatible for applications where 240V AC and 48V DC operation is acceptable. If the system requires the full 250V AC and 50V DC ratings, E-T-A parametric equivalents are the appropriate choice.

Q: What is the difference between E-T-A series 1140, 127, and 1410-G1 variants?

A: All three E-T-A series maintain identical electrical specifications (5A, 250V AC, 50V DC, thermal, single-pole, push-to-reset). Differences exist in mechanical packaging, mounting configurations, and internal design variants. Selection depends on physical space constraints and panel integration requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, matching the original TS-709-5H specification.

Q: Which substitute part has the highest inventory availability?

A: The E-T-A 1140-G151-P7M1-5A offers the highest inventory at 2100 units, followed by 1410-G114-P3F1-S01-5A at 1169 units.

Q: Do all substitute parts carry the same certifications as the TS-709-5H?

A: E-T-A parametric equivalents carry expanded certifications (CSA C22.2 No 235, IEC 60934, UL1077) beyond the original part's CSA C22.2 and UL1077. The SCHURTER 4404.0025 includes additional certifications: EN 60934 and GB 17701.
