Key Parameters

Substitute Part Grouping Explanation

The WLCA2-LD-N qualifies as a functional substitute based on the following alignment of critical parameters:

• Circuit Configuration: Both parts maintain SPDT (DB/DM) topology
• Switch Function: Both operate in On-Mom mode
• Actuator Type: Both feature side rotary roller actuation
• Mounting Type: Both are chassis mount configurations
• Termination Style: Both use screw terminals
• Ingress Protection: Both meet IP67 specification
• Operating Temperature Range: Both operate across -10°C ~ 80°C
• Voltage Rating - AC: Both rated at 125 V AC
• Voltage Rating - DC: Both rated at 30 V DC

The WLCA2-LD-N represents an upgraded variant within the Omron WL series with enhanced current handling capacity (10A AC / 6A DC versus 100mA) and active product status, making it suitable for applications where the original component is no longer available.

Parameter Comparison

Engineering Selection Recommendations

The WLCA2-LD-N is the designated substitute for the obsolete WL01CA2-LD. Selection is based on:

• Product Status: The WLCA2-LD-N maintains active product status with confirmed inventory availability (865 Pcs), whereas the WL01CA2-LD is obsolete with limited remaining stock (714 Pcs).
• Compliance: The WLCA2-LD-N is RoHS Compliant and REACH Unaffected, providing regulatory alignment for new designs and long-term supply chain stability.
• Electrical Equivalence: All critical electrical parameters (voltage ratings, circuit topology, switch function) are identical between the two parts.
• Mechanical Equivalence: Actuator type, mounting configuration, and termination style are fully compatible.
• Environmental Rating: Both parts maintain identical IP67 ingress protection and operating temperature specifications.

The WLCA2-LD-N's higher current rating (10A AC / 6A DC) does not compromise compatibility in applications designed for the original 100mA specification, as the substitute operates within the same voltage and environmental constraints.

Frequently Asked Questions (FAQ)

Q: Can the WLCA2-LD-N directly replace the WL01CA2-LD in existing assemblies?

A: Yes. Both parts share identical circuit configuration (SPDT DB/DM), switch function (On-Mom), actuator type (side rotary roller), mounting type (chassis mount), termination style (screw terminal), voltage ratings (125V AC / 30V DC), and ingress protection (IP67). Physical and electrical compatibility is confirmed.

Q: What is the primary difference between these two parts?

A: The WLCA2-LD-N features enhanced current handling capacity (10A AC / 6A DC) compared to the WL01CA2-LD (100mA AC/DC). The substitute also maintains active product status with RoHS compliance, whereas the original is obsolete.

Q: Are there packaging differences between the WL01CA2-LD and WLCA2-LD-N?

A: The WL01CA2-LD is supplied with standard packaging, while the WLCA2-LD-N is supplied in bulk packaging. Both use screw terminal connections and are suitable for chassis mount applications.

Q: Does the WLCA2-LD-N meet the same environmental specifications?

A: Yes. Both parts are rated for IP67 ingress protection (dust tight, waterproof) and operate across the identical temperature range of -10°C to 80°C.

Q: What is the mechanical life expectancy of the substitute part?

A: The WLCA2-LD-N is rated for 15,000,000 mechanical cycles, matching the original WL01CA2-LD specification.
