Key Parameters

Substitute Part Grouping Explanation

Substitution of the WLH12-TH with the WLCA12-TH-N is based on functional equivalence within the Omron Automation and Safety product family. Both components are manufactured by the same supplier and maintain active product status. The WLCA12-TH-N operates as a snap action switch with defined electrical ratings, mechanical characteristics, and environmental protection specifications that establish it as a direct substitute within the WL-N series classification.

The substitution logic is determined by the following key parameters:

• Manufacturer consistency (Omron Automation and Safety)
• Active product status for both components
• Bulk packaging configuration
• Functional switch classification
• Compliance certifications (RoHS Compliant, REACH Unaffected)

Parameter Comparison

Engineering Selection Recommendations

Selection between WLH12-TH and WLCA12-TH-N should be based on the following engineering criteria:

Product Status: Both components maintain active product status with Omron Automation and Safety, ensuring continued availability and manufacturer support.

Compliance Certifications: The WLCA12-TH-N provides documented RoHS Compliance and REACH Unaffected status. When regulatory compliance documentation is required for the application, the WLCA12-TH-N offers explicit certification records.

Inventory Availability: The WLH12-TH maintains higher stock levels (889 units) compared to the WLCA12-TH-N (698 units), which may influence lead time considerations for immediate procurement requirements.

Electrical and Mechanical Specifications: The WLCA12-TH-N provides complete specification documentation including circuit configuration (SPDT DB/DM), current ratings (10A AC / 6A DC), voltage ratings (125V AC / 30V DC), actuator type (Side Rotary, Adjustable Roller), mounting type (Chassis Mount), and termination style (Screw Terminal).

Frequently Asked Questions (FAQ)

Q: Can the WLCA12-TH-N directly replace the WLH12-TH in existing applications?

A: Both components are manufactured by Omron Automation and Safety and maintain active product status. Substitution is valid within the parameters specified for each component. Verify that the application requirements align with the electrical ratings, mechanical characteristics, and mounting specifications of the substitute part.
