WLCA2-LDS Equivalent & Substitute Parts

Part Overview

The WLCA2-LDS is an Omron Automation and Safety snap action switch with SPDT (DB/DM) circuit configuration, rated for 10A AC at 125V and 6A DC at 30V. This component is classified as obsolete, making identification of compatible substitute parts essential for ongoing maintenance and new design implementations. The switch features chassis mount installation with screw terminal connections, IP67 ingress protection, and side rotary roller actuation suitable for industrial control applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the WLCA2-LDS is determined by strict equivalence in the following critical parameters:

Mandatory Equivalence Parameters:

• Circuit configuration: SPDT (DB/DM)
• Switch function: On-Mom
• Actuator type: Side Rotary, Roller
• Mounting type: Chassis Mount
• Termination style: Screw Terminal
• Ingress protection: IP67
• Operating temperature range: -10°C to 80°C
• Electrical life: 750,000 Cycles
• Mechanical life: 15,000,000 Cycles

Allowable Variation Parameters:

• AC voltage rating: 115V to 125V (within industrial standard tolerance)
• DC voltage rating: 24V to 30V (within industrial standard tolerance)
• Current ratings: 10A AC / 6A DC (maintained across substitutes)
• Release force: Variation permitted within mechanical design tolerance
• Overtravel: Variation permitted within mechanical design tolerance

The WLCA2-LDS-N meets all mandatory equivalence criteria and operates within allowable variation ranges for voltage and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The WLCA2-LDS-N is the direct substitute for the obsolete WLCA2-LDS. Selection is based on the following engineering criteria:

Product Status: The WLCA2-LDS-N is classified as Active, ensuring continued availability and supply chain reliability compared to the obsolete WLCA2-LDS.

Compliance: The WLCA2-LDS-N is RoHS Compliant, meeting current environmental and regulatory requirements. The original WLCA2-LDS has undefined RoHS status, making the substitute preferable for new designs and compliance-sensitive applications.

Electrical Equivalence: Both parts maintain identical current ratings (10A AC / 6A DC) and circuit configuration (SPDT DB/DM). The AC voltage rating difference (125V vs. 115V) and DC voltage rating difference (30V vs. 24V) fall within industrial standard operating tolerances and do not affect functional compatibility in standard control circuits.

Mechanical Equivalence: Both parts share identical actuator type, mounting configuration, termination style, and life cycle ratings. Variations in release force (227gf vs. 120gf) and overtravel (30° vs. 70°) represent design refinements within the WL-N series and do not compromise substitution suitability.

Inventory Availability: The WLCA2-LDS-N maintains adequate stock (800 Pcs) for immediate procurement, whereas the obsolete WLCA2-LDS has limited remaining inventory (832 Pcs).

Frequently Asked Questions (FAQ)

Q: Can the WLCA2-LDS-N directly replace the WLCA2-LDS in existing installations?

A: Yes. Both parts share identical circuit configuration (SPDT DB/DM), current ratings (10A AC / 6A DC), actuator type (Side Rotary Roller), mounting type (Chassis Mount), and termination style (Screw Terminal). The voltage rating differences (125V AC vs. 115V AC; 30V DC vs. 24V DC) are within industrial standard operating tolerances and do not affect functional compatibility.

Q: What is the significance of the product status change from Obsolete to Active?

A: The WLCA2-LDS is classified as obsolete, indicating discontinued production and limited remaining inventory. The WLCA2-LDS-N is active production, ensuring long-term availability, consistent supply chain access, and manufacturer support. For new designs and ongoing maintenance, the active substitute is the recommended selection.

Q: Are there compliance differences between the two parts?

A: The WLCA2-LDS-N is RoHS Compliant, meeting current environmental regulations. The WLCA2-LDS has undefined RoHS status. For applications requiring regulatory compliance documentation, the WLCA2-LDS-N is the appropriate choice.

Q: How do the mechanical parameter differences affect substitution?

A: The release force difference (227gf vs. 120gf) and overtravel difference (30° vs. 70°) represent design refinements within the WL-N series. Both parts maintain identical operating force (1360gf), pretravel (15°), and differential travel (12°). These variations fall within mechanical design tolerance and do not compromise functional substitution.

Q: What packaging differences exist between these parts?

A: The WLCA2-LDS is supplied in standard packaging format. The WLCA2-LDS-N is supplied in Bulk packaging. Packaging selection should be based on procurement volume and inventory management requirements.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both parts operate across the identical temperature range of -10°C to 80°C and maintain the same electrical life (750,000 cycles) and mechanical life (15,000,000 cycles).
