Engineering Selection Recommendations

All listed substitute parts maintain identical electrical specifications (8A, 240V AC, 60V DC) and mechanical configuration (panel mount, rocker actuator, dual-pole). Selection between TA45 and TA35 series variants is determined by application-specific mechanical envelope requirements, as both series meet the same electrical and regulatory criteria.

All substitute parts carry Active product status and ROHS3 compliance. Parts with documented approval agencies (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077) are suitable for applications requiring these specific certifications. Parts without explicitly listed approval agencies should be cross-referenced with application requirements before selection.

Inventory availability ranges from 677 to 1031 pieces across all substitute options, enabling supply chain flexibility for production requirements.

Frequently Asked Questions (FAQ)

Q: Can TA35 series parts substitute for TA45 series parts? A: Yes. Both TA35 and TA45 series parts listed meet identical electrical ratings (8A, 240V AC, 60V DC), mounting type (panel mount), actuator type (rocker), and pole configuration (2-pole). Series designation reflects internal design architecture but does not affect electrical or mechanical interchangeability for the specified parameters.

Q: What are the key parameters that determine substitutability? A: Substitutability is determined by: current rating (8A), AC voltage (240V), DC voltage (60V), breaker type (thermal), mounting type (panel mount), actuator type (rocker), and number of poles (2). All listed substitutes match these parameters exactly.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All substitute parts listed carry ROHS3 Compliant status and REACH Unaffected designation, meeting environmental regulatory requirements.

Q: Do all substitute parts carry the same regulatory approvals? A: Most substitute parts carry CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077 approvals. Part 4435.0272 does not list approval agencies in the provided data. Verify specific approval requirements for your application before selection.

Q: What is the difference between parts with "Not Applicable" and "Vendor Undefined" MSL ratings? A: Moisture Sensitivity Level (MSL) designation does not affect circuit breaker functionality or substitutability. Both designations indicate the component's moisture handling classification. This parameter does not restrict interchangeability.

Q: Can I use these parts interchangeably in existing designs? A: Yes, provided your application requires 8A thermal circuit protection at 240V AC / 60V DC with panel mount rocker actuator configuration. Mechanical envelope and connector compatibility should be confirmed for your specific panel design.
