Substitute Part Grouping Explanation

Substitute parts for the 4435.0076 are qualified based on the following critical parameters that determine functional interchangeability:

Electrical Equivalence Criteria:

Current Rating: 2A (exact match required)
Voltage Rating - AC: 240V (exact match required)
Voltage Rating - DC: 60V (exact match required)
Breaker Type: Thermal (exact match required)

Mechanical Equivalence Criteria:

Mounting Type: Panel Mount (exact match required)
Actuator Type: Rocker (exact match required)
Number of Poles: 2 (exact match required)

Compliance Criteria:

RoHS3 Compliant (maintained across all substitutes)
REACH Unaffected (maintained across all substitutes)

All identified substitute parts meet these criteria and are manufactured by SCHURTER Inc. Substitutes span two series designations: TA35 and TA45, both of which provide identical electrical and mechanical performance for this application.

Engineering Selection Recommendations

All substitute parts listed are active products manufactured by SCHURTER Inc. and maintain full ROHS3 compliance and REACH unaffected status. Selection among equivalent parts should be based on:

Availability: Inventory levels vary across part numbers. Parts 4430.2302 (1132 pcs), 4430.2451 (1031 pcs), and 4430.3743 (1065 pcs) offer the highest stock levels for immediate procurement.

Series Compatibility: TA35 series parts (4435.0076, 4435.0306, 4435.0466) and TA45 series parts (4430.004, 4430.2296, 4430.2302, 4430.2451, 4430.2569, 4430.309, 4430.3171, 4430.3743) are functionally equivalent. Series selection should be based on existing design documentation and PCB layout requirements.

Regulatory Approvals: Parts 4430.004, 4430.2296, 4430.2302, 4430.2451, 4430.309, and 4430.3171 carry explicit approval agency certifications (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077). These certifications provide additional assurance for applications requiring documented compliance.

Frequently Asked Questions (FAQ)

Q: Can I substitute a TA45 series part for the original TA35 series 4435.0076?

A: Yes. Both TA35 and TA45 series parts meet identical electrical and mechanical specifications for this 2A 240VAC 60VDC thermal circuit breaker application. Series designation reflects internal design evolution but does not affect functional performance or interchangeability.

Q: What parameters must remain constant when selecting a substitute?

A: Current rating (2A), AC voltage (240V), DC voltage (60V), breaker type (thermal), mounting type (panel mount), actuator type (rocker), and pole count (2) must all match exactly. Any deviation in these parameters indicates the part is not a true substitute.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed, including the main part 4435.0076 and all substitutes, are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Does inventory level affect substitution eligibility?

A: No. Inventory levels do not determine substitution eligibility. All listed parts are functionally equivalent regardless of stock quantity. Inventory information is provided for procurement planning purposes only.

Q: Which substitute parts have the most comprehensive regulatory approvals?

A: Parts 4430.004, 4430.2296, 4430.2302, 4430.2451, 4430.309, and 4430.3171 carry explicit approvals from CSA, EN, GB, IEC, and UL standards bodies. These certifications may be required for specific applications or markets.

Q: Can I mix TA35 and TA45 series parts in the same circuit design?

A: Yes. Both series are electrically and mechanically equivalent for this specification. However, design consistency and documentation should reflect the actual series used in production.
