Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following critical parameters: breaker type (thermal), current rating (2.5A), AC voltage rating (240V), DC voltage rating (60V), mounting type (panel mount), actuator type (rocker), and pole configuration (2-pole). All substitute parts listed maintain identical electrical and mechanical specifications to the main part number 4430.0543, ensuring direct functional equivalence. Series designation (TA45 or TA35) does not restrict substitution when all electrical parameters align.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, meeting current regulatory requirements. Part 4430.3462 offers the highest current inventory at 1131 pieces. Part 4435.0215 represents an alternative series designation (TA35) while maintaining identical electrical specifications. Selection should be based on availability, supply chain lead times, and internal design documentation requirements. All parts are manufactured by SCHURTER Inc. and carry equivalent REACH Unaffected and EAR99 ECCN classifications.

Frequently Asked Questions (FAQ)

Q: Can 4430.1638 replace 4430.0543 in existing designs? A: Yes. Both parts share identical electrical ratings (2.5A, 240V AC, 60V DC), thermal breaker type, rocker actuator, 2-pole configuration, and panel mount design. Series designation TA45 is common to both.

Q: What is the difference between TA45 and TA35 series parts? A: Series designation does not affect electrical or mechanical compatibility when all specified parameters match. Part 4435.0215 (TA35 series) is electrically and mechanically equivalent to TA45 series parts for this application.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed parts including 4430.0543, 4430.1638, 4430.3462, and 4435.0215 are ROHS3 compliant.

Q: Can these parts be used interchangeably in the same circuit? A: Yes. All parts are parametric equivalents with identical current ratings, voltage ratings, breaker type, and mounting configuration, enabling direct substitution.

Q: What packaging format is available? A: All parts are supplied in Bulk packaging.
