Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance. Parts designated 4430.0683, 4430.1486, and 4430.2103 include documented approval agency certifications (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077). Selection between TA45 series (4430.xxxx) and TA35 series (4435.xxxx) variants is based on application requirements and mechanical form factor compatibility, as all electrical parameters remain identical. Inventory availability ranges from 718 to 1677 units across the substitute population.

Frequently Asked Questions (FAQ)

Q: Can 4435.0022 (TA35 series) directly replace 4430.3091 (TA45 series)?

A: Yes. Both parts share identical electrical specifications (3A, 240V AC, 60V DC) and mechanical mounting characteristics (panel mount, rocker actuator, dual-pole). Series designation reflects internal design architecture but does not affect functional interchangeability when all electrical and mechanical parameters match.

Q: What parameters must remain constant for substitution?

A: Current rating (3A), AC voltage (240V), DC voltage (60V), breaker type (thermal), mounting type (panel mount), actuator type (rocker), and pole count (2) must all remain unchanged. Any deviation in these parameters disqualifies a part as a direct substitute.

Q: Are there differences in regulatory compliance between substitute parts?

A: Parts 4430.0683, 4430.1486, and 4430.2103 include explicit approval agency documentation. Other parts maintain ROHS3 compliance without listed certifications in the provided data. Compliance requirements for your specific application determine whether documented certifications are necessary.

Q: Does packaging affect substitution eligibility?

A: All parts are supplied in bulk packaging. Packaging format does not affect electrical or mechanical interchangeability.

Q: Which substitute part has the highest inventory availability?

A: Part 4435.0022 (TA35 series) maintains 1677 units in stock, the highest availability among all substitutes listed.
