Substitute Part Grouping Explanation

Substitute parts for the 4435.0424 are qualified based on the following critical parameters that determine functional equivalence:

Current Rating: 20A (exact match required)
Voltage Rating - AC: 240V (exact match required)
Voltage Rating - DC: 60V (exact match required)
Breaker Type: Thermal (exact match required)
Mounting Type: Panel Mount (exact match required)
Actuator Type: Rocker (exact match required)
Number of Poles: 2 (exact match required)
RoHS Status: ROHS3 Compliant (compliance requirement)

All identified substitute parts meet these electrical and mechanical parameters. Parts from the TA45 series are included as they maintain identical functional specifications while differing only in series designation. Substitution is valid across series boundaries when all electrical and mechanical parameters align.

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance, meeting regulatory requirements for current applications. Parts 4430.0572, 4430.1067, 4430.1068, and 4430.161 include documented approval agency certifications (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077), providing additional validation for applications requiring multi-standard compliance. Selection between substitute parts should be based on inventory availability and any design-specific requirements related to series designation or approval certifications.

Frequently Asked Questions (FAQ)

Q: Can TA45 series parts directly replace the TA35 series 4435.0424?

A: Yes. All TA45 substitute parts listed maintain identical electrical ratings (20A, 240V AC, 60V DC), breaker type (thermal), mounting configuration (panel mount), actuator type (rocker), and pole count (2). Series designation does not affect functional equivalence when all electrical and mechanical parameters match.

Q: What parameters must match for a part to be considered a substitute?

A: Current rating, voltage ratings (both AC and DC), breaker type, mounting type, actuator type, and number of poles must all match exactly. All listed substitutes meet these criteria.

Q: Are there differences in RoHS compliance among the substitute parts?

A: All substitute parts are ROHS3 compliant. Moisture sensitivity level designations vary (Not Applicable or Vendor Undefined), but this does not affect substitution eligibility for the specified application parameters.

Q: Which substitute parts have additional approval certifications?

A: Parts 4430.0572, 4430.1067, 4430.1068, and 4430.161 include approval agency certifications. These certifications provide additional validation for applications requiring compliance with CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, or UL1077 standards.

Q: Does inventory level affect substitution validity?

A: No. Inventory levels are provided for procurement planning purposes only and do not affect technical substitution eligibility. All parts are available in production quantities.
