Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WLH2-TH is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPDT (DB/DM)
• Switch function: On-Mom
• Current rating: 10A AC minimum, 6A DC minimum
• Voltage rating: 125V AC minimum, 30V DC minimum
• Actuator type: Side rotary roller
• Mounting type: Chassis mount
• Termination style: Screw terminal
• Ingress protection: IP67 minimum

The WLCA2-TH-N meets all substitution criteria. Both parts maintain identical electrical specifications, actuator configuration, mounting interface, and environmental protection rating. The substitute part is classified as active product status with enhanced mechanical life rating and RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

The WLCA2-TH-N is the direct functional equivalent for WLH2-TH applications. Both parts share identical electrical ratings, mechanical interface specifications, and environmental protection characteristics. The WLCA2-TH-N offers the advantage of active product status, ensuring continued availability and supply chain support. The substitute part carries RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The enhanced mechanical life rating of 15,000,000 cycles compared to 10,000,000 cycles provides extended operational durability in high-cycle applications.

Frequently Asked Questions (FAQ)

Q: Can WLCA2-TH-N directly replace WLH2-TH in existing applications?

A: Yes. Both parts maintain identical current ratings (10A AC, 6A DC), voltage ratings (125V AC, 30V DC), circuit configuration (SPDT), actuator type (side rotary roller), mounting interface (chassis mount), and termination style (screw terminal). Electrical and mechanical compatibility is complete.

Q: What are the differences between WLH2-TH and WLCA2-TH-N?

A: The primary differences are product status and mechanical life. WLH2-TH is obsolete with 10,000,000 cycle mechanical life. WLCA2-TH-N is active product with 15,000,000 cycle mechanical life. WLCA2-TH-N includes RoHS3 compliance and REACH unaffected certification.

Q: Are there packaging differences between these parts?

A: WLH2-TH is supplied with unspecified packaging. WLCA2-TH-N is supplied in bulk packaging. Verify packaging requirements for your procurement process.

Q: What is the operating force difference between these parts?

A: WLH2-TH specifies 1000gf operating force with 100gf release force. WLCA2-TH-N specifies 1360gf operating force with 120gf release force. Both values remain within acceptable ranges for side rotary roller actuator applications.

Q: Are compliance certifications equivalent?

A: WLCA2-TH-N carries RoHS3 compliance and REACH unaffected status. WLH2-TH compliance status is vendor undefined. For applications requiring regulatory compliance documentation, WLCA2-TH-N is the appropriate selection.
