Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the WL01CA2 is determined by the following critical parameters:

Circuit Configuration & Function: Both the main part and substitute must maintain SPDT (DB/DM) circuit topology with On-Mom switch function to ensure electrical compatibility with existing control logic.

Mechanical Interface: Identical actuator type (side rotary roller), mounting method (chassis mount), and termination style (screw terminal) are required to ensure physical installation without modification.

Environmental Rating: IP67 ingress protection must be maintained to preserve dust-tight and waterproof performance in the intended application environment.

Electrical Ratings: Voltage ratings (125V AC, 30V DC) and operating temperature range (-10°C ~ 80°C) must be met or exceeded by substitute components.

Lifecycle Specifications: Mechanical life rating of 15,000,000 cycles is a baseline requirement. Electrical life may vary based on current rating differences.

The WLCA2-N qualifies as a direct substitute based on these parameters, with the primary distinction being an increased current rating capacity.

Parameter Comparison

Engineering Selection Recommendations

The WLCA2-N is the qualified substitute for the obsolete WL01CA2 based on the following engineering criteria:

Functional Equivalence: Both components share identical circuit topology (SPDT DB/DM), switch function (On-Mom), mechanical interface (side rotary roller, chassis mount, screw terminal), and environmental protection (IP67).

Electrical Compatibility: Voltage ratings and operating temperature ranges are identical. The WLCA2-N current rating (10A AC / 6A DC) exceeds the WL01CA2 rating (100mA AC/DC), making it suitable for applications operating at or below the original current specification.

Production Status: The WLCA2-N is classified as active product status with ROHS3 compliance and REACH unaffected designation, ensuring long-term availability and regulatory alignment.

Mechanical Lifecycle: Both components maintain the same mechanical life rating (15,000,000 cycles), supporting equivalent operational durability in chassis mount applications.

Frequently Asked Questions (FAQ)

Q: Can the WLCA2-N directly replace the WL01CA2 without circuit modification?

A: Yes. Both components maintain identical SPDT (DB/DM) circuit configuration, On-Mom switch function, voltage ratings (125V AC / 30V DC), and screw terminal connections. No circuit redesign is required.

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

A: The WLCA2-N has a significantly higher current rating (10A AC / 6A DC) compared to the WL01CA2 (100mA AC/DC). The WLCA2-N is suitable for applications requiring the original 100mA specification or lower.

Q: Are the mechanical interfaces identical?

A: Yes. Both components feature side rotary roller actuators, chassis mount configuration, and screw terminal termination. Physical installation is identical.

Q: Does the WLCA2-N maintain IP67 ingress protection?

A: Yes. The WLCA2-N maintains IP67 rating (dust tight, waterproof), matching the environmental protection of the WL01CA2.

Q: What is the packaging difference?

A: The WL01CA2 is supplied with dash packaging, while the WLCA2-N is supplied in bulk packaging. This affects order quantities and handling but does not impact component functionality.

Q: Is the WLCA2-N compliant with current regulations?

A: Yes. The WLCA2-N is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: Can I use the WLCA2-N in applications requiring the exact 100mA current rating?

A: Yes. The WLCA2-N current rating (10A AC / 6A DC) exceeds the 100mA requirement, making it suitable for applications operating at or below this specification.
