Engineering Selection Recommendations

All listed substitute parts are parametrically equivalent to the TS-701-HT-20/RI3 and maintain identical electrical and mechanical specifications. Selection among substitutes should be based on the following factors:

Product Status: E-T-A and TE Connectivity parts are classified as Active, ensuring long-term availability and continued manufacturing support compared to the obsolete SCHURTER original.

Compliance & Certifications: E-T-A substitutes carry approval certifications including CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077. TE Connectivity W58 series maintains RoHS compliance. All parts are ECCN EAR99 classified and REACH unaffected.

Inventory Availability: E-T-A 2-5000-P10-20A offers the highest inventory level at 1134 pieces, followed by 2-5000-P10-H-20A at 1069 pieces, providing supply security for volume requirements.

Series Considerations: E-T-A 127 series (P10, P11, K10 variants) and 157 series provide direct substitution. E-T-A 2-5000 series offers alternative platform options with equivalent performance. TE Connectivity W58 series provides cross-manufacturer substitution capability.

Frequently Asked Questions (FAQ)

Q: Can E-T-A 127 series parts directly replace the SCHURTER TS-701-HT-20/RI3?

A: Yes. The 127-P10-H-KF-20A, 127-P10-H-KF-050022-20A, 127-P10-H-KF-D91-20A, and 127-P11-H-KF-20A are parametrically equivalent across all critical specifications: 20A current rating, 250V AC / 50V DC voltage ratings, thermal breaker type, push-to-reset actuation, and panel mount configuration.

Q: What is the difference between E-T-A 127 and 2-5000 series substitutes?

A: Both series meet identical electrical and mechanical parameters for this application. The 127 series and 2-5000 series represent different product platforms within E-T-A's thermal circuit breaker portfolio. Selection between them depends on design integration preferences and packaging requirements.
