Engineering Selection Recommendations

All listed substitute parts are direct parametric equivalents to the main part 4430.322. Selection among these alternatives is based on the following engineering criteria:

Compliance and Certification: All substitute parts carry Active product status and ROHS3 compliance. Parts 4430.0586, 4430.0847, 4430.0977, 4430.1201, 4430.1353, 4430.1384, 4430.1564, 4430.1856, 4430.1926, and 4430.2297 are certified to CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077 standards where specified in the data.

Inventory Availability: Part 4430.1201 offers the highest inventory level at 1518 pieces, followed by 4430.1353 at 1131 pieces and 4430.1856 at 1186 pieces. These options provide optimal supply chain continuity for high-volume applications.

Functional Interchangeability: All substitute parts maintain identical electrical ratings (5A, 240V AC, 60V DC), thermal breaker operation, dual-pole configuration, and rocker panel mount design. No electrical or mechanical modifications are required for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can any of these substitute parts replace the 4430.322 in my application?

A: Yes. All listed substitute parts are parametric equivalents with identical current ratings (5A), voltage ratings (240V AC / 60V DC), breaker type (thermal), mounting configuration (panel mount rocker), and pole count (2). Direct substitution is supported without circuit modification.

Q: Are all substitute parts certified to the same standards as the main part?

A: All substitute parts carry ROHS3 compliance and Active product status. Certification to CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077 is specified for all parts listed. Consult individual datasheets for complete certification details where MSL or REACH status differs.

Q: What is the difference between these part numbers if they are all equivalent?

A: The part numbers represent different manufacturing batches, date codes, or internal SCHURTER production variants. All electrical and mechanical specifications remain identical across the TA45 series for this rating class. Differences are internal to SCHURTER manufacturing processes and do not affect performance or compatibility.

Q: Which substitute part should I select for new designs?

A: Selection should prioritize inventory availability and lead time requirements. Part 4430.1201 (1518 pcs available) provides the strongest supply position. All parts are functionally equivalent, so procurement and logistics considerations should drive the selection decision.

Q: Are there any packaging or mounting differences between these parts?

A: All substitute parts are specified as Bulk packaging with Panel Mount configuration. No packaging or mounting variations exist among the listed equivalents. Physical dimensions and mounting hole patterns are identical across all TA45 series parts at this rating.
