Engineering Selection Recommendations

All listed substitute parts are Active product status and ROHS3 compliant, meeting current regulatory requirements. Selection among equivalent parts should be based on:

TA45 Series (Primary Equivalents): Parts 4430.004, 4430.2296, 4430.2302, 4430.2451, 4430.2569, 4430.309, 4430.3171, and 4430.3743 maintain identical electrical and mechanical specifications to the 4430.1037. These parts carry approval certifications including CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077 where documented.

TA35 Series (Mechanical Variants): Parts 4435.0306 and 4435.0466 are mechanically distinct variants within the TA35 series but maintain identical electrical ratings and panel mount configuration. These are suitable for applications where TA35 form factor compatibility is required.

Inventory Availability: Selection may be influenced by current stock levels. Part 4430.2302 maintains the highest inventory at 1132 pieces, while 4430.309 maintains the lowest at 686 pieces.

Frequently Asked Questions (FAQ)

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

A: TA35 and TA45 series parts (4435.0306 and 4435.0466) are mechanically distinct variants. Substitution is permissible only if the application design accommodates the TA35 form factor. Electrical specifications are identical across both series for the listed parts.

Q: What determines if a part is a true equivalent?

A: True equivalents match all critical parameters: 2A current rating, 240V AC and 60V DC voltage ratings, thermal breaker type, panel mount configuration, rocker actuator, and dual-pole design. All listed parts meet these criteria.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 Compliant status, meeting current environmental and regulatory standards.

Q: Do all parts carry the same approval certifications?

A: Most substitute parts carry CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077 certifications. Part 4430.1037 and 4430.2569 do not list specific approval agencies in the provided data. Part 4430.3743 does not list specific approval agencies. Verify certification requirements for your specific application.

Q: What is the difference between parts with "Not Applicable" and "Vendor Undefined" MSL ratings?

A: Moisture Sensitivity Level (MSL) classifications indicate handling requirements during storage and transport. "Not Applicable" indicates the component does not require MSL classification. "Vendor Undefined" indicates the manufacturer has not specified an MSL rating. Both designations are acceptable for standard industrial applications.

Q: Can I use these parts interchangeably in existing designs?

A: Yes, all listed substitute parts are direct electrical and mechanical equivalents for the 4430.1037 within their respective series families. Panel mount configuration and rocker actuator design are consistent across all parts.
