Substitute Part Grouping Explanation

Substitute parts for the 4430.0423 are qualified based on the following critical parameters:

Current Rating: 8A (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)
Product Status: Active (required for current availability)
RoHS Status: ROHS3 Compliant (required for regulatory compliance)

All substitute parts listed meet these criteria. Parts are grouped by series designation: TA45 series (4430.xxxx prefix) and TA35 series (4435.xxxx prefix). Both series share identical electrical and mechanical specifications for this 8A 240VAC 60VDC configuration.

Engineering Selection Recommendations

All listed substitute parts are active production components with ROHS3 compliance. Selection between TA45 and TA35 series variants is determined by panel cutout and mounting hole specifications, which are not differentiated in the provided electrical parameters. Within each series, all part numbers are electrically and functionally equivalent for the 8A 240VAC 60VDC application.

Parts with documented approval agencies (4430.0646, 4430.1631, 4430.2237, 4430.2269, 4430.3661, 4435.009, 4435.0272, 4435.0345, 4435.0356) carry certifications including CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. Selection should account for inventory availability and any specific certification requirements for the target application.

Frequently Asked Questions (FAQ)

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

A: TA35 and TA45 series parts share identical electrical specifications (8A, 240VAC, 60VDC, thermal, rocker, 2-pole, panel mount). Substitution is determined by mechanical compatibility with the panel cutout and mounting configuration. Verify panel hole spacing and cutout dimensions before substitution.

Q: What electrical parameters must match for direct substitution?

A: Current rating (8A), 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 disqualifies a part as a direct substitute.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed are ROHS3 compliant and suitable for applications requiring RoHS compliance.

Q: Do all substitute parts have the same certifications?

A: Most substitute parts carry CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077 certifications. The main part 4430.0423 and part 4435.0272 do not list specific approval agencies in the provided data. Verify certification requirements for your specific application.

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

A: Both designations indicate that Moisture Sensitivity Level is not a controlling factor for these components. No special moisture handling is required during storage or assembly.
