Engineering Selection Recommendations

SCHURTER Inc. Parametric Equivalent (TS-701-HT-12-K): TS-701-HT-12-K is a direct parametric equivalent from the same manufacturer with identical electrical specifications (12A, 250V AC, 50V DC). Both parts share the TS series designation and obsolete product status. This option provides continuity with the original design intent and manufacturer support. Inventory availability is 1,041 units.

Active Status Alternatives: For new designs or systems requiring active product support, the following parts are recommended based on product status and compliance certifications:

E-T-A 1140 Series (1140-F111-P1M1-12A, 1140-G111-P1M1-12A, 1140-G151-P7M1-12A): All three variants maintain identical electrical ratings and are classified as active products. These parts carry CSA C22.2 No 235, IEC 60934, and UL1077 certifications. Inventory ranges from 642 to 823 units.
E-T-A 127 Series (127-P10-H-KF-12A): Active product with identical electrical specifications. Certifications include CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077. Inventory: 797 units.
E-T-A 2-5000 Series (2-5000-P10-H-12A): Active product with identical electrical specifications. Certifications include CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077. Inventory: 919 units.
Carling Technologies CTB Series (CTB-B-B-12): Active product with identical electrical specifications. Certifications include CE, cUL, UL1077, and VDE. Moisture sensitivity level is 1 (Unlimited). Inventory: 1,312 units.

SCHURTER Inc. Voltage Variant (4404.0023): This part differs in voltage ratings (240V AC, 48V DC versus 250V AC, 50V DC) and is classified as active. This option is suitable only for applications with lower voltage requirements and should not be used as a direct substitute for the TS-701-HT-12H without circuit verification.

Frequently Asked Questions (FAQ)

Q: Can TS-701-HT-12-K be used as a direct replacement for TS-701-HT-12H? A: Yes. Both parts are manufactured by SCHURTER Inc., share identical electrical ratings (12A, 250V AC, 50V DC), and have matching mechanical specifications (panel mount, push-to-reset, single pole). The only difference is the part number suffix, which indicates a design variant within the same product family.

Q: What is the difference between the E-T-A 1140 series variants (1140-F111-P1M1-12A, 1140-G111-P1M1-12A, 1140-G151-P7M1-12A)? A: All three variants maintain identical electrical and mechanical specifications for the TS-701-HT-12H application. The alphanumeric designations (F111, G111, G151) represent internal design variations within the E-T-A 1140 series. Selection among these variants should be based on availability and internal design documentation from E-T-A.

Q: Is the SCHURTER 4404.0023 a suitable substitute? A: The 4404.0023 has different voltage ratings (240V AC, 48V DC) compared to the TS-701-HT-12H (250V AC, 50V DC). This part is not a direct substitute and should only be used if the application circuit operates at the lower voltage specifications. Verify circuit requirements before selection.

Q: What certifications apply to substitute parts? A: E-T-A parts carry CSA C22.2 No 235, IEC 60934, and UL1077 certifications (with some variants including GB 17701). Carling Technologies CTB-B-B-12 carries CE, cUL, UL1077, and VDE certifications. All substitute parts are ROHS3 compliant and REACH unaffected.

Q: Are there packaging differences among substitute parts? A: Yes. The TS-701-HT-12H is supplied in bulk packaging. The SCHURTER 4404.0023 is supplied in box packaging. All other substitutes use bulk packaging. Verify packaging requirements for procurement and inventory management.

Q: Which substitute part has the highest inventory availability? A: Carling Technologies CTB-B-B-12 has the highest inventory with 1,312 units in stock. SCHURTER TS-701-HT-12-K has 1,041 units, and E-T-A 2-5000-P10-H-12A has 919 units.

Q: Should I prioritize active or obsolete product status when selecting a substitute? A: For new designs or long-term applications, active products are recommended to ensure ongoing manufacturer support and supply continuity. The TS-701-HT-12H and TS-701-HT-12-K are both obsolete; however, multiple active alternatives with identical specifications are available from E-T-A and Carling Technologies.
