Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WLCA12-2-TS is determined by strict equivalence across the following critical parameters:

Circuit configuration must remain SPDT (DB/DM) to maintain identical switching topology. Current and voltage ratings must meet or exceed the original specifications: 10A AC minimum, 6A DC minimum, 125V AC minimum, and 30V DC minimum. Actuator type, mounting configuration, and termination style must be identical to ensure mechanical and electrical compatibility within the existing assembly. Ingress protection rating must maintain IP67 classification for environmental sealing. Operating force, release force, and travel characteristics must match the original specifications to preserve actuation behavior and system response.

The substitute part WLCA122TSN meets all these criteria, maintaining complete electrical and mechanical equivalence while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The WLCA122TSN is the direct functional equivalent of the WLCA12-2-TS. Both components share identical electrical ratings, mechanical specifications, and physical form factors. The primary distinction is product status: WLCA12-2-TS is obsolete, while WLCA122TSN maintains active status with current manufacturing support.

WLCA122TSN carries ROHS3 compliance and REACH unaffected certification, providing regulatory alignment for applications subject to environmental and chemical restriction requirements. The active product status ensures ongoing availability and supply chain continuity.

For applications requiring the WLCA12-2-TS, direct substitution with WLCA122TSN is appropriate without design modification or re-qualification, provided the application environment and electrical load parameters remain within the specified ratings.

Frequently Asked Questions (FAQ)

Q: Can WLCA122TSN directly replace WLCA12-2-TS in existing assemblies?

A: Yes. Both components are electrically and mechanically identical across all critical parameters: circuit configuration, current and voltage ratings, actuator type, mounting configuration, termination style, and ingress protection. No design changes are required.

Q: What is the significance of the product status difference?

A: WLCA12-2-TS is obsolete and no longer manufactured. WLCA122TSN is active and currently produced by Omron, ensuring supply availability and ongoing technical support.

Q: Are there compliance differences between the two parts?

A: WLCA122TSN carries ROHS3 compliance and REACH unaffected certification. The original WLCA12-2-TS compliance status is not specified. For applications subject to environmental regulations, WLCA122TSN provides documented compliance.

Q: What packaging options are available?

A: WLCA12-2-TS was supplied in unspecified packaging. WLCA122TSN is available in bulk packaging.

Q: Are the mechanical and electrical life ratings identical?
