Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory alignment with the original 4430.3021 specification. Part 4430.0706 carries additional approval certifications including CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077, providing enhanced documentation for applications requiring third-party validation. Part 4430.2421 similarly includes the same approval agency certifications.

Selection between TA45 series variants (4430.xxxx) and TA35 series variants (4435.xxxx) depends on mechanical form factor compatibility within the target application, as both series satisfy identical electrical performance requirements. Inventory availability ranges from 626 to 1191 pieces across all qualified substitutes, supporting procurement flexibility.

Frequently Asked Questions (FAQ)

Q: Can TA35 series parts (4435.xxxx) directly replace TA45 series parts (4430.xxxx)?

A: Yes. Both series are qualified substitutes based on matching electrical ratings (4A, 240V AC, 60V DC), thermal breaker type, rocker actuator, 2-pole configuration, and panel mount form factor. Series designation reflects internal design variants that do not affect functional interchangeability for the specified electrical parameters.

Q: What determines whether a part qualifies as a substitute for 4430.3021?

A: Substitution is based on matching current rating (4A), AC voltage (240V), DC voltage (60V), breaker type (thermal), mounting configuration (panel mount), actuator style (rocker), and pole count (2). All listed parts meet these criteria.

Q: Are there differences in approval certifications among the substitute parts?

A: Parts 4430.0706 and 4430.2421 include documented approvals from CSA, EN, GB, IEC, and UL standards. Other parts maintain ROHS3 compliance and active status without listed third-party certifications in the provided data. Applications requiring specific certification documentation should reference 4430.0706 or 4430.2421.

Q: How should I select between multiple substitute options?

A: Selection criteria include series preference (TA45 vs TA35), inventory availability, and certification requirements. All parts are electrically and mechanically equivalent for the specified 4A 240VAC 60VDC thermal circuit breaker application.

Q: Is the MSL (Moisture Sensitivity Level) rating consistent across all parts?

A: Most parts are rated as Not Applicable. Part 4430.34 is listed as Vendor Undefined. This parameter does not affect substitution eligibility for thermal circuit breaker applications.
