Substitute Part Grouping Explanation

Substitution eligibility is determined by strict parametric equivalence across the following criteria:

Current Rating: 3A (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)
Product Status: Active (required for current procurement)
RoHS Status: ROHS3 Compliant (required for regulatory compliance)

All substitute parts listed below meet these criteria. Series designation (TA35 or TA45) and approval agency certifications vary by part number but do not affect electrical or mechanical interchangeability for the specified application parameters.

Engineering Selection Recommendations

All listed substitute parts are active products with ROHS3 compliance and identical electrical and mechanical specifications to the 4435.0127. Selection between TA35 and TA45 series variants depends on application-specific approval agency requirements. Parts 4430.0683, 4430.1486, and 4435.0022 carry explicit approval certifications (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077) and are suitable for applications requiring documented compliance to these standards. Parts without listed approval agencies are suitable for applications where such certifications are not mandated. Inventory levels range from 718 to 1677 units across all substitutes, supporting procurement flexibility.

Frequently Asked Questions (FAQ)

Q: Can I substitute 4435.0127 with any part from the substitute list?

A: Yes. All listed parts are parametric equivalents with identical current rating (3A), voltage ratings (240V AC / 60V DC), mounting configuration (panel mount rocker), and pole count (2). Electrical and mechanical interchangeability is assured.

Q: What is the difference between TA35 and TA45 series?

A: Series designation indicates internal design generation. Both TA35 and TA45 variants meet the specified electrical and mechanical parameters. Series selection is determined by application requirements and approval agency certifications, not by electrical performance.

Q: Do all substitutes carry the same approval certifications?

A: No. Parts 4430.0683, 4430.1486, and 4435.0022 carry explicit certifications (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077). Other parts are ROHS3 compliant but do not list specific approval agencies. Select parts with required certifications for regulated applications.

Q: Are there inventory considerations for part selection?

A: Yes. Inventory availability ranges from 718 to 1677 units. Parts 4435.0022 (1677 Pcs), 4430.3416 (1151 Pcs), and 4430.3377 (1135 Pcs) offer highest stock levels for immediate procurement.

Q: Is the 4435.0127 still in active production?

A: Yes. The 4435.0127 maintains active product status with 736 units in stock. All substitute parts are also active products, ensuring long-term availability and support.
