WL01CL-LD Equivalent & Substitute Parts

Part Overview

The WL01CL-LD is an Omron Automation and Safety snap-action switch with SPDT (double-break, double-make) circuit configuration, rated for 0.1A at 125V AC and 30V DC. This component features a side rotary actuator with adjustable rod, chassis mount configuration, and IP67 ingress protection suitable for dust-tight and waterproof applications. The product is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing system maintenance and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the WL01CL-LD is determined by the following critical parameters that must remain consistent or be compatible with the original application:

Mandatory Compatibility Parameters:

• Circuit configuration: SPDT (DB/DM) maintained
• Switch function: On-Momentary operation preserved
• Actuator type: Side rotary with adjustable rod
• Mounting type: Chassis mount
• Termination style: Screw terminal
• Ingress protection: IP67 rating
• Operating temperature range: -10°C to 80°C minimum
• Voltage rating: 125V AC and 30V DC minimum

Allowable Variation Parameters:

• Current rating: May exceed 100mA if application permits
• Electrical life: May differ from 1,000,000 cycles
• Mechanical life: May differ from 15,000,000 cycles
• Product status: Active status preferred for long-term availability

The WLCL-LD-N meets all mandatory compatibility parameters while providing enhanced current capacity and active product status.

Engineering Selection Recommendations

The WLCL-LD-N is the direct substitute for the obsolete WL01CL-LD. Both components share identical mechanical and electrical interface specifications, including circuit topology, actuator configuration, mounting method, and environmental protection rating.

The WLCL-LD-N provides the following advantages:

• Active product status ensures continued availability and supply chain stability
• RoHS compliance and REACH unaffected status provide regulatory alignment for modern applications
• Enhanced current capacity (10A AC / 6A DC) accommodates higher-load applications without requiring circuit redesign
• Identical voltage ratings, temperature range, and mechanical interface eliminate redesign requirements

The reduction in electrical life from 1,000,000 to 750,000 cycles is acceptable for applications where the original component was not selected specifically for extended cycle life. Applications requiring the original 1,000,000-cycle specification should be evaluated against actual duty cycle requirements.

Frequently Asked Questions (FAQ)

Q: Can the WLCL-LD-N directly replace the WL01CL-LD without circuit modification?

A: Yes. Both components maintain identical SPDT circuit configuration, voltage ratings (125V AC / 30V DC), actuator type, mounting method, and termination style. No circuit redesign is required for direct substitution.

Q: What is the impact of the increased current rating on the WLCL-LD-N?

A: The WLCL-LD-N supports 10A AC and 6A DC compared to the WL01CL-LD's 100mA rating. This higher capacity is backward-compatible with applications originally designed for 100mA operation. Applications requiring higher current loads can utilize the WLCL-LD-N without additional circuit modifications.

Q: Does the difference in electrical life affect substitution suitability?

A: The WLCL-LD-N provides 750,000 electrical cycles versus the original 1,000,000 cycles. This difference is acceptable unless the original design specifically required extended cycle life. Verify actual application duty cycles to confirm adequacy.

Q: Are there packaging differences between these components?

A: The WL01CL-LD is packaged as individual units, while the WLCL-LD-N is supplied in bulk packaging. Both use identical screw terminal connections and chassis mount configuration.

Q: What regulatory compliance improvements does the WLCL-LD-N provide?

A: The WLCL-LD-N is RoHS compliant and REACH unaffected, providing alignment with current environmental and chemical regulations. The original WL01CL-LD has undefined REACH status and unspecified RoHS compliance.

Q: Are both components rated for the same environmental conditions?

A: Yes. Both the WL01CL-LD and WLCL-LD-N maintain IP67 ingress protection (dust tight, waterproof) and operate across the identical temperature range of -10°C to 80°C.
