WLCA2-LD Snap Action Switch - Equivalent & Substitute Parts

Part Overview

The WLCA2-LD is an Omron Automation and Safety snap action switch featuring SPDT (double-break/double-make) circuitry with a 10A AC / 6A DC current rating at 125V AC / 30V DC. This chassis-mounted switch utilizes a side rotary roller actuator with screw terminal connections and IP67 ingress protection. The product is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WLCA2-LD is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPDT (DB/DM) topology
• Current ratings: 10A AC and 6A DC minimum
• Voltage ratings: 125V AC and 30V DC minimum
• Actuator type: Side rotary roller mechanism
• Mounting interface: Chassis mount configuration
• Termination: Screw terminal connections
• Environmental sealing: IP67 classification
• Operating temperature range: -10°C to 80°C
• Electrical and mechanical life cycles

The WLCA2-LD-N meets all substitution criteria as an active product within the Omron WL series family, maintaining identical electrical specifications, mechanical interface, and environmental ratings while offering improved product availability and ongoing manufacturer support.

Parameter Comparison

Engineering Selection Recommendations

The WLCA2-LD-N is the direct active equivalent for the obsolete WLCA2-LD. Both parts maintain identical electrical performance specifications, mechanical interface geometry, and environmental protection ratings. The WLCA2-LD-N provides the additional advantage of active product status with confirmed RoHS compliance and REACH unaffected classification, supporting regulatory requirements for new equipment designs and long-term supply chain continuity.

Selection of the WLCA2-LD-N is appropriate for direct replacement in existing applications and for new designs requiring SPDT snap action switching at 10A AC / 6A DC with IP67 environmental sealing and chassis mount configuration.

Frequently Asked Questions (FAQ)

Q: Can WLCA2-LD-N directly replace WLCA2-LD in existing assemblies?

A: Yes. The WLCA2-LD-N maintains identical electrical ratings (10A AC / 6A DC at 125V AC / 30V DC), circuit configuration (SPDT), actuator type (side rotary roller), mounting interface (chassis mount), termination style (screw terminal), and environmental protection (IP67). Physical and electrical compatibility is complete.

Q: What is the difference between WLCA2-LD and WLCA2-LD-N?

A: The primary differences are product status and regulatory compliance. WLCA2-LD is obsolete with undefined RoHS and REACH status. WLCA2-LD-N is an active product with RoHS compliance and REACH unaffected classification. Packaging differs (standard versus bulk). All electrical and mechanical specifications are identical.

Q: Are there packaging considerations when switching from WLCA2-LD to WLCA2-LD-N?

A: Yes. WLCA2-LD is supplied in standard packaging, while WLCA2-LD-N is supplied in bulk packaging. Procurement and inventory management processes may require adjustment to accommodate bulk packaging requirements.

Q: Does WLCA2-LD-N meet current regulatory requirements?

A: Yes. WLCA2-LD-N is RoHS compliant and REACH unaffected, meeting current regulatory requirements for electronic components in most jurisdictions.

Q: What are the key parameters that define substitution compatibility for this switch family?

A: Substitution compatibility is determined by SPDT circuit configuration, 10A AC / 6A DC current ratings, 125V AC / 30V DC voltage ratings, side rotary roller actuator type, chassis mount interface, screw terminal termination, IP67 ingress protection, -10°C to 80°C operating temperature range, and specified electrical and mechanical life cycles.
