Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TS-701-HT-4 is determined by the following critical parameters:

• Current Rating: 4A (exact match required)
• Voltage Rating - AC: 250V (exact match required)
• Voltage Rating - DC: 50V (exact match required)
• Breaker Type: Thermal (exact match required)
• Mounting Type: Panel Mount (exact match required)
• Actuator Type: Push to Reset (exact match required)
• Number of Poles: 1 (exact match required)

Substitute parts are classified into two categories:

Parametric Equivalents – Parts matching all critical electrical and mechanical parameters with active product status and current manufacturing availability.

Similar Alternatives – Parts with minor voltage deviations (±10V AC, ±2V DC tolerance) that maintain functional compatibility within standard industrial operating ranges.

Parameter Comparison

Engineering Selection Recommendations

Preferred Parametric Equivalents – Direct replacements with identical electrical specifications (250V AC, 50V DC, 4A):

• 1140-G111-P1M1-4A (E-T-A, Series 1140)
• 1140-G151-P7M1-4A (E-T-A, Series 1140)
• 127-P10-H-KF-4A (E-T-A, Series 127)
• 1410-G110-P2F1-S01-4A (E-T-A, Series 1410-G1)
• 1410-G111-P2F1-S01-4A (E-T-A, Series 1410-G1)
• 2-5000-P10-H-4A (E-T-A, Series 2-5000)
• CTB-B-B-04 (Carling Technologies, Series CTB)
• W58-XB1A15B-4 (TE Connectivity Potter & Brumfield Relays, Series W58)

All parametric equivalents maintain active product status and carry UL1077 certification. E-T-A variants provide additional IEC 60934 compliance. Carling Technologies CTB-B-B-04 offers CE and VDE certifications. TE Connectivity W58-XB1A15B-4 provides RoHS compliance.

Alternative with Voltage Tolerance – Acceptable for applications with reduced DC voltage requirements:

• 4404.0019 (SCHURTER Inc., Series T9-311) – 240V AC, 48V DC. Maintains same manufacturer lineage with expanded international certifications (EN 60934, GB 17701).

• CLB-043-11ANN-R-A (Carling Technologies, Series CLB) – 250V AC, 32V DC. Suitable where DC voltage margin exists. Carries CE, cUL, TUV, and UL1500 certifications.

Frequently Asked Questions (FAQ)

Q: Can I use 4404.0019 as a direct replacement for TS-701-HT-4?

A: 4404.0019 is functionally compatible with minor voltage deviations. It maintains 4A current rating and 250V AC specification but operates at 240V AC and 48V DC versus the original 250V AC and 50V DC. This part is suitable for applications where the system voltage tolerance accommodates these reductions.

Q: What is the difference between parametric equivalents and similar alternatives?

A: Parametric equivalents match all electrical and mechanical specifications exactly: 4A, 250V AC, 50V DC, thermal type, panel mount, push-to-reset actuation, and single pole. Similar alternatives deviate in voltage ratings but maintain the same current rating and functional characteristics.

Q: Are all substitute parts RoHS compliant?

A: Most substitutes carry ROHS3 compliance. W58-XB1A15B-4 is RoHS compliant. Verify specific RoHS certification requirements for your application before selection.

Q: Which substitute offers the broadest international certification coverage?

A: 4404.0019 provides CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077 certifications. E-T-A variants (1140 and 1410 series, 127-P10-H-KF-4A, 2-5000-P10-H-4A) include CSA C22.2 No 235, IEC 60934, and UL1077. Carling Technologies CTB-B-B-04 carries CE, cUL, UL1077, and VDE approvals.

Q: Can I mix different substitute part manufacturers in the same system?

A: All substitutes maintain identical functional specifications and mounting characteristics. Cross-manufacturer substitution is permissible provided the application circuit design does not depend on manufacturer-specific thermal response curves or mechanical tolerances.

Q: What packaging options are available?

A: Substitute parts are available in Box (4404.0019) and Bulk packaging (all E-T-A, Carling Technologies, and TE Connectivity variants). Verify packaging requirements for your procurement and assembly processes.

Q: Is the TS-701-HT-4 still available for purchase?

A: The TS-701-HT-4 is classified as obsolete. Current inventory of 1041 pieces may be available through authorized distributors, but long-term availability is not guaranteed. Selection of an active-status substitute is recommended for new designs and ongoing production.
