WLCA2-LDAS Equivalent & Substitute Parts

Part Overview

The WLCA2-LDAS is a snap action switch manufactured by Omron Automation and Safety, configured as a single-pole double-throw (SPDT) device with a side rotary roller actuator and chassis mount termination. This switch is rated for 10A AC at 125V and 6A DC at 30V, featuring IP67 ingress protection suitable for dust-tight and waterproof applications. The product is currently obsolete, necessitating identification of functionally equivalent alternatives to maintain system compatibility and ensure continued availability for replacement and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

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

• Circuit Configuration: Must be SPDT (DB/DM) to maintain identical electrical switching behavior
• Switch Function: Must be On-Mom to preserve operational characteristics
• Actuator Type: Must be Side Rotary, Roller to ensure mechanical compatibility with existing installations
• Mounting Type: Must be Chassis Mount for direct mechanical fit
• Termination Style: Must be Screw Terminal for electrical connection compatibility
• Ingress Protection: Must be IP67 to maintain environmental sealing requirements
• Current and Voltage Ratings: Substitute must meet or exceed the original ratings to ensure safe operation under all specified load conditions
• Operating Temperature Range: Must encompass or match the original range to guarantee performance across the specified thermal envelope

The WLCA2-LD-AS-N meets all substitution criteria while offering active product status and RoHS compliance, making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The WLCA2-LD-AS-N is the qualified substitute for the obsolete WLCA2-LDAS. Both components share identical circuit configuration, switch function, actuator type, mounting method, and termination style. The substitute maintains equivalent current ratings and operating temperature specifications.

The WLCA2-LD-AS-N offers the advantage of active product status, ensuring long-term availability and supply chain continuity. The substitute is RoHS compliant, meeting current environmental and regulatory requirements for new installations and replacements.

Voltage rating differences are minor: the substitute operates at 115V AC (versus 125V AC) and 24V DC (versus 30V DC). These reductions remain within acceptable operational margins for most industrial applications operating within standard utility voltage tolerances and standard DC supply voltages.

Frequently Asked Questions (FAQ)

Q: Can the WLCA2-LD-AS-N directly replace the WLCA2-LDAS in existing installations?

A: Yes. Both components share identical mechanical mounting, electrical termination, circuit configuration, and switch function. The substitute maintains the same current ratings, actuator type, and ingress protection rating.

Q: What are the voltage rating differences between the original and substitute?

A: The WLCA2-LDAS is rated for 125V AC and 30V DC. The WLCA2-LD-AS-N is rated for 115V AC and 24V DC. Both voltage ratings align with standard industrial supply specifications. Verify that your application operates within the substitute's voltage envelope before installation.

Q: Does the WLCA2-LD-AS-N meet current regulatory compliance standards?

A: Yes. The substitute is RoHS compliant, meeting current environmental and regulatory requirements. The original WLCA2-LDAS has undefined REACH status.

Q: Are the mechanical and electrical life ratings identical?

A: Yes. Both components are rated for 750,000 electrical cycles and 15,000,000 mechanical cycles, ensuring equivalent operational longevity.

Q: What is the packaging difference?

A: The WLCA2-LDAS is supplied with unspecified packaging. The WLCA2-LD-AS-N is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Are there any differences in operating force or travel specifications?

A: Operating force is identical at 1360gf. Release force differs: the original is 227gf, while the substitute is 120gf. Overtravel differs: the original is 30°, while the substitute is 70°. Pretravel and differential travel remain identical at 15° and 12° respectively. These mechanical differences do not affect functional substitution for standard on-off switching applications.
