Engineering Selection Recommendations

All substitute parts listed are parametrically equivalent to the TS-701-HT-30 and are suitable for direct replacement. Selection among available substitutes should be based on the following factors:

Product Status: All substitute parts are classified as Active, ensuring ongoing manufacturing support and availability compared to the obsolete TS-701-HT-30.

Compliance & Certifications: The TS-701-HT-30 carries CSA C22.2 and UL1077 approvals. E-T-A substitutes (127 series and 2-5000 series) provide expanded certifications including CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077. TE Connectivity W58 series parts maintain UL1077 compliance.

RoHS Compliance: The TS-701-HT-30 is ROHS3 Compliant. E-T-A 127 series and 2-5000 series parts are ROHS3 Compliant. W58-XC4C12A-30 is ROHS3 Compliant; other W58 variants are RoHS Compliant.

Inventory Availability: W58-XC4C12A-30 offers the highest inventory level at 1469 pieces. E-T-A 127-P10-H-KF-30A provides 962 pieces. All substitutes maintain adequate stock for production requirements.

Frequently Asked Questions (FAQ)

Q: Are all listed parts direct replacements for the TS-701-HT-30?

A: Yes. All substitute parts match the TS-701-HT-30 across all critical electrical and mechanical parameters: 30A current rating, 250V AC / 50V DC voltage ratings, thermal breaker type, panel mount configuration, push-to-reset actuation, and single-pole design.

Q: What is the primary reason to substitute the TS-701-HT-30?

A: The TS-701-HT-30 is classified as obsolete. Active substitute parts from E-T-A and TE Connectivity ensure continued availability, manufacturing support, and compliance with current standards.

Q: Do the E-T-A 127 series parts offer additional certifications?

A: Yes. E-T-A 127 series parts (127-P10-H-KF-050022-30A, 127-P10-H-KF-30A, 127-P10-H-KF-D91-30A) include certifications for CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077, providing broader international compliance compared to the original TS-701-HT-30.

Q: What is the difference between the E-T-A 127 series variants?

A: All three E-T-A 127 series variants (127-P10-H-KF-050022-30A, 127-P10-H-KF-30A, 127-P10-H-KF-D91-30A) are parametrically identical. Differences exist only in part number designation and packaging specifications. Selection should be based on procurement requirements and packaging preferences.

Q: Which substitute offers the best inventory availability?

A: W58-XC4C12A-30 from TE Connectivity offers the highest inventory at 1469 pieces, followed by W58-XB1A15B-30 at 990 pieces.

Q: Are there RoHS compliance differences among the substitutes?

A: Yes. W58-XC4C12A-30 is ROHS3 Compliant, matching the original TS-701-HT-30. Other W58 variants are RoHS Compliant. E-T-A parts are ROHS3 Compliant. For applications requiring ROHS3 compliance, select W58-XC4C12A-30 or E-T-A substitutes.

Q: Can I use W58 series parts interchangeably with E-T-A 127 series parts?

A: Yes. All listed substitutes are parametrically equivalent and electrically interchangeable. Selection should be based on compliance requirements, inventory availability, and procurement preferences.
