WLRCA2-LD Equivalent & Substitute Parts

Part Overview

The WLRCA2-LD is an Omron Automation and Safety snap action switch with SPDT (double-break, double-make) circuit configuration, rated for 10A at 125V AC and 6A at 30V DC. This component features chassis mount installation with screw terminal connections and IP67 ingress protection. The product is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing system maintenance and new designs requiring this switch topology.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WLRCA2-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 without lever
• Mounting configuration: Chassis mount with screw terminals
• Environmental protection: IP67 rating
• Operational characteristics: On-momentary switch function
• Temperature operating range: -10°C to 80°C
• Lifecycle specifications: 750,000 electrical cycles and 15,000,000 mechanical cycles

The WLRCA2-LD-N qualifies as a direct substitute based on complete parameter alignment across all specified electrical, mechanical, and environmental criteria.

Parameter Comparison

Engineering Selection Recommendations

The WLRCA2-LD-N is the direct equivalent for applications currently using the WLRCA2-LD. The substitute maintains identical electrical performance specifications, mechanical characteristics, and environmental protection ratings. The WLRCA2-LD-N carries active product status with RoHS compliance certification, providing regulatory alignment for new designs and ongoing procurement. The transition from the obsolete WLRCA2-LD to the WLRCA2-LD-N requires no circuit redesign or mechanical modification, as all functional parameters remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can the WLRCA2-LD-N be used as a direct replacement for the WLRCA2-LD?

A: Yes. The WLRCA2-LD-N provides complete functional equivalence across all specified electrical ratings, circuit topology, mechanical mounting, and environmental protection parameters. No design modifications are required.

Q: What is the primary difference between these two part numbers?

A: The WLRCA2-LD is obsolete, while the WLRCA2-LD-N is an active product with RoHS compliance certification. The series designation changed from WL to WL-N, and packaging is specified as bulk for the substitute.

Q: Are the current and voltage ratings identical?

A: Yes. Both parts are rated for 10A at 125V AC and 6A at 30V DC, with identical operating temperature ranges and lifecycle specifications.

Q: Does the packaging difference affect compatibility?

A: Packaging designation (bulk for WLRCA2-LD-N versus unspecified for WLRCA2-LD) does not affect electrical or mechanical compatibility. This reflects supply chain configuration only.

Q: Is RoHS compliance required for my application?

A: The WLRCA2-LD-N is RoHS compliant. If your application or regulatory environment requires RoHS certification, the WLRCA2-LD-N satisfies this requirement while the original part does not specify compliance status.
