Substitute Part Grouping Explanation

Substitution eligibility is determined by strict parametric equivalence across the following criteria:

Current Rating: 15A (exact match required)
Voltage Rating AC: 240V (exact match required)
Voltage Rating DC: 60V (exact match required)
Breaker Type: Thermal (exact match required)
Mounting Type: Panel Mount (exact match required)
Actuator Type: Rocker (exact match required)
Number of Poles: 2 (exact match required)
Manufacturer: SCHURTER Inc. (exact match required)
RoHS Status: ROHS3 Compliant (exact match required)

All substitute parts listed below meet these criteria. Series designation (TA35 or TA45) does not restrict substitution eligibility when all electrical and mechanical parameters are identical.

Engineering Selection Recommendations

All listed substitute parts are Active product status and ROHS3 compliant, meeting current regulatory requirements. Multiple substitute options carry CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077 certifications, providing additional compliance documentation where required by application standards.

Selection between the main part (4435.0355, TA35 series) and substitute parts (TA45 series) is determined by availability, inventory levels, and design documentation requirements. All parts are functionally equivalent for applications requiring 15A thermal circuit protection at 240V AC / 60V DC with rocker panel mount actuation.

Frequently Asked Questions (FAQ)

Q: Can TA45 series parts substitute for the TA35 series main part?

A: Yes. When all electrical parameters (15A, 240V AC, 60V DC), mechanical configuration (thermal breaker, rocker actuator, panel mount, 2-pole), and compliance status (ROHS3) are identical, TA45 parts are direct parametric equivalents to the TA35 main part.

Q: What determines if a part is a valid substitute?

A: Substitution requires exact matching of current rating, voltage ratings (AC and DC), breaker type, mounting configuration, actuator type, pole count, and manufacturer. All listed parts meet these criteria.

Q: Are there differences in certifications between parts?

A: The main part 4435.0355 lists no specific approval agencies. Multiple TA45 substitute parts carry CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077 certifications. Verify certification requirements for your application before selection.

Q: Does series designation affect substitution?

A: Series designation alone does not restrict substitution when all electrical and mechanical parameters are identical. Both TA35 and TA45 series parts in this list are parametrically equivalent.

Q: What is the inventory status for substitute parts?

A: Inventory levels vary by part number. Part 4430.1089 has the highest stock (2961 pcs), while 4430.0885 has the lowest (687 pcs). Verify current availability with your supplier for time-sensitive applications.
