WLCA2-7LD Equivalent & Substitute Parts

Part Overview

The WLCA2-7LD is an Omron Automation and Safety snap action switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 10A at 125V AC and 6A at 30V DC. This chassis-mounted switch features a side rotary roller actuator with screw terminal connections and IP67 ingress protection. The product is currently obsolete, necessitating identification of equivalent substitute components for ongoing maintenance and new designs requiring this switch topology.

Key Parameters

Substitute Part Grouping Explanation

The WLCA2-7LD-N qualifies as a direct substitute based on the following critical parameters that determine functional equivalence:

• Circuit Configuration: Both parts maintain SPDT topology
• Current Rating: Identical 10A AC and 6A DC ratings
• Voltage Rating: Matching 125V AC and 30V DC specifications
• Actuator Type: Both feature side rotary roller actuators
• Mounting Type: Both are chassis-mounted with screw terminals
• Ingress Protection: Both provide IP67 protection
• Operating Temperature: Identical -10°C to 80°C range
• Electrical Life: Both rated for 750,000 cycles
• Mechanical Life: Both rated for 15,000,000 cycles

The WLCA2-7LD-N is classified as an active product within the WL-N series, providing continued availability and supply chain support compared to the obsolete WLCA2-7LD.

Parameter Comparison

Engineering Selection Recommendations

The WLCA2-7LD-N is the designated substitute for the obsolete WLCA2-7LD. Both components share identical electrical and mechanical specifications across all critical parameters that determine functional compatibility. The WLCA2-7LD-N maintains active product status within the WL-N series, ensuring continued availability and supply chain support.

Minor variations exist in release force (170gf versus 92gf) and overtravel (30° versus 70°), which reflect design refinements in the active product line. These differences do not affect the core switching function or electrical performance in standard applications.

The WLCA2-7LD-N is available in bulk packaging, supporting both replacement and new design applications. Selection of the active substitute eliminates obsolescence risk and provides access to current manufacturing and support resources.

Frequently Asked Questions (FAQ)

Q: Can the WLCA2-7LD-N directly replace the WLCA2-7LD in existing applications?

A: Yes. Both components share identical circuit configuration (SPDT), current ratings (10A AC, 6A DC), voltage ratings (125V AC, 30V DC), actuator type (side rotary roller), mounting type (chassis mount), termination style (screw terminal), and ingress protection (IP67). Electrical and mechanical life specifications are identical.

Q: What are the differences between the WLCA2-7LD and WLCA2-7LD-N?

A: The primary differences are product status and packaging. The WLCA2-7LD is obsolete; the WLCA2-7LD-N is active. The WLCA2-7LD-N is supplied in bulk packaging. Release force differs (92gf versus 170gf) and overtravel differs (70° versus 30°), reflecting design refinements in the active product line.

Q: Are there any compliance or certification differences between these parts?

A: The WLCA2-7LD-N is classified as REACH Unaffected. RoHS compliance status differs between the parts. Both carry ECCN EAR99 classification.

Q: What is the impact of the different release force values?

A: Release force determines the force required to return the actuator to its neutral position after activation. The WLCA2-7LD-N requires less release force (92gf) compared to the WLCA2-7LD (170gf). This represents a design refinement and does not affect compatibility in standard switching applications.

Q: What is the significance of the different overtravel specifications?

A: Overtravel is the additional distance the actuator travels beyond the switching point. The WLCA2-7LD-N provides greater overtravel (70° versus 30°), offering increased mechanical tolerance and durability in the active product design.
