Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance. Parts 4430.2166, 4430.2295, 4430.2301, and 4430.2307 carry additional regulatory certifications including CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. These certifications provide expanded approval scope for applications requiring multi-standard compliance.

TA45 series parts (4430.xxxx) and TA35 series parts (4435.xxxx) are electrically and mechanically equivalent. Series selection depends on application-specific mechanical envelope requirements and existing design documentation. Cross-series substitution is permissible when electrical and mechanical parameters align.

Frequently Asked Questions (FAQ)

Q: Can TA45 series parts be substituted with TA35 series parts? A: Yes. Both series maintain identical electrical specifications (500mA, 240V AC, 60V DC) and mechanical mounting characteristics (panel mount, rocker actuator, 2-pole configuration). Series designation reflects design generation; functional equivalence is maintained across series boundaries.

Q: What determines if a part is a valid substitute? A: Valid substitutes must match all critical parameters: 500mA current rating, 240V AC and 60V DC voltage ratings, thermal breaker type, panel mount configuration, rocker actuator, and 2-pole design. All listed parts meet these requirements.

Q: Are there differences in regulatory approvals among the substitute parts? A: Yes. Parts 4430.2166, 4430.2295, 4430.2301, and 4430.2307 carry CSA, EN, GB, IEC, and UL certifications. Other parts carry ROHS3 compliance only. Selection should align with application certification requirements.

Q: What is the inventory status for substitute parts? A: All substitute parts are in active production with current stock levels ranging from 648 to 969 units. Inventory quantities are provided in the parameter comparison table for procurement planning.

Q: Can substitutes be used interchangeably in existing designs? A: Yes, within the same series or across series boundaries, provided the application design documentation does not specify a particular part number. Mechanical fit and electrical performance are equivalent across all listed substitutes.
