Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, qualifying them for direct replacement in applications requiring 500mA thermal circuit protection at 240V AC and 60V DC. Parts designated 4430.2166, 4430.2295, 4430.2301, and 4430.2307 carry additional approval certifications including CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077, providing expanded regulatory acceptance for international applications. Selection between TA45 and TA35 series variants depends on mechanical fit requirements within the target panel mount assembly, as both series maintain identical electrical specifications.

Frequently Asked Questions (FAQ)

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

A: Yes. Both series maintain identical electrical ratings (500mA, 240V AC, 60V DC), breaker type (thermal), mounting configuration (panel mount), and actuator type (rocker). Series designation reflects design generation or mechanical envelope variations, not functional differences. Verify mechanical fit within the panel mount assembly before installation.

Q: What is the difference between parts with and without approval agency certifications?

A: Parts 4430.2166, 4430.2295, 4430.2301, and 4430.2307 carry documented approvals from CSA, EN, GB, IEC, and UL standards bodies. Parts without listed certifications remain compliant with RoHS3 and REACH requirements. Selection depends on regulatory requirements for the end application.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant status. Part 4430.231 lists MSL as Vendor Undefined; all others specify Not Applicable for Moisture Sensitivity Level.

Q: What inventory levels are available for each substitute part?

A: Inventory ranges from 648 Pcs (4430.2301) to 969 Pcs (4430.2792). Current stock levels support high-volume procurement across all substitute options.

Q: Are there any electrical or mechanical parameter differences between substitute parts?

A: No. All substitute parts are parametrically equivalent. Current rating, voltage ratings, breaker type, mounting type, actuator type, and pole count are identical across all listed alternatives.
