Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance. TA45 series substitutes (4430.0024, 4430.1034, 4430.1637, 4430.242, 4430.2693, 4430.3041, 4430.3223, 4430.3263) provide direct series equivalence to the primary part 4430.366. TA35 series alternatives (4435.0092, 4435.0223) deliver identical electrical and mechanical performance with alternative series designation. Selection between TA45 and TA35 series depends on application-specific mechanical fit requirements and PCB layout constraints. All parts satisfy the same regulatory certifications: CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077.

Frequently Asked Questions (FAQ)

Q: Can TA35 series parts replace TA45 series parts? A: Yes. Parts 4435.0092 and 4435.0223 maintain identical electrical ratings (12A, 240V AC, 60V DC), breaker type (thermal), mounting configuration (panel mount), actuator type (rocker), and pole count (2). Series designation reflects mechanical form factor; functional equivalence is confirmed.

Q: What determines if a part is a valid substitute? A: Substitution requires matching current rating (12A), AC voltage (240V), DC voltage (60V), breaker type (thermal), mounting type (panel mount), actuator type (rocker), and pole count (2). All listed parts meet these criteria.

Q: Are all substitute parts in stock? A: Inventory availability varies. Current stock levels are provided in the parameter comparison table. Verify availability with your supplier before component selection.

Q: Do all substitute parts comply with the same standards? A: TA45 series parts comply with CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. TA35 series parts (4435.0092, 4435.0223) maintain ROHS3 compliance and equivalent electrical performance; verify specific certification requirements for your application.

Q: What is the difference between part numbers within the same series? A: All TA45 series parts share identical electrical and mechanical specifications. Part number variations reflect internal manufacturing or distribution designations and do not affect functional performance or interchangeability.
