WLCL-LD Snap Action Switch - Equivalent & Substitute Parts

Part Overview

The WLCL-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 a side rotary actuator with adjustable rod, chassis mount termination via screw terminals, and IP67 ingress protection suitable for dust-tight and waterproof applications. The part is classified as obsolete, making identification of equivalent substitute components necessary for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the WLCL-LD is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPDT (DB/DM) topology
• Current and voltage ratings: 10A at 125V AC; 6A at 30V DC
• Actuator type and mounting: Side rotary with adjustable rod; chassis mount
• Termination method: Screw terminal
• Environmental protection: IP67 rating
• Operating temperature range: -10°C to 80°C
• Electrical and mechanical life specifications: 750,000 and 15,000,000 cycles respectively

The WLCL-LD-N meets all these criteria and is classified as an active product, making it a direct functional equivalent suitable for replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The WLCL-LD-N is the direct substitute for the obsolete WLCL-LD. Both components share identical electrical ratings, circuit topology, and mechanical specifications across all critical parameters. The WLCL-LD-N offers the advantage of active product status, ensuring continued availability and supply chain support. Additionally, the WLCL-LD-N carries RoHS compliance certification and confirmed REACH unaffected status, providing regulatory alignment for applications subject to environmental compliance requirements. The minor differences in release force (27gf versus 28gf) and overtravel (70° versus 30°) do not affect functional equivalence for standard snap action switch applications within the specified electrical and mechanical operating ranges.

Frequently Asked Questions (FAQ)

Q: Can the WLCL-LD-N directly replace the WLCL-LD in existing applications?

A: Yes. The WLCL-LD-N maintains identical electrical ratings (10A at 125V AC, 6A at 30V DC), circuit configuration (SPDT), actuator type (side rotary with adjustable rod), mounting method (chassis mount), and termination style (screw terminal). All critical functional parameters are equivalent.

Q: What is the difference in packaging between these parts?

A: The WLCL-LD is supplied in standard packaging, while the WLCL-LD-N is supplied in bulk packaging. Packaging format does not affect component functionality or electrical performance.

Q: Why is the WLCL-LD classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The WLCL-LD-N, classified as active, represents the current production equivalent and is the recommended selection for new designs and ongoing maintenance applications.

Q: Are there compliance differences between the two parts?

A: The WLCL-LD-N carries RoHS compliance certification and REACH unaffected status. The WLCL-LD has vendor-undefined REACH status. For applications requiring regulatory compliance documentation, the WLCL-LD-N is the appropriate selection.

Q: Do the differences in overtravel specifications affect substitution suitability?

A: No. The WLCL-LD-LD features 30° overtravel while the WLCL-LD-N features 70° overtravel. Both values remain within acceptable operating ranges for snap action switch applications and do not compromise functional equivalence for standard circuit control applications.

Q: What is the mechanical life expectancy for both parts?

A: Both the WLCL-LD and WLCL-LD-N are rated for 15,000,000 mechanical cycles, providing equivalent durability and service life in repetitive switching applications.
