• Mounting type: Both employ chassis mount configuration
• Termination style: Both utilize screw terminals
• Ingress protection: Both provide IP67 rating
• Operating temperature range: Both operate within -10°C ~ 80°C
• Voltage rating - AC: Both rated for 125V AC
• Voltage rating - DC: Both rated for 30V DC

The WLCA2-LD-N represents an active product with enhanced electrical and mechanical performance characteristics compared to the obsolete WL01H2-LD.

Parameter Comparison

Engineering Selection Recommendations

The WLCA2-LD-N is the direct substitute for the obsolete WL01H2-LD. Both components share identical circuit topology, actuator configuration, mounting methodology, and environmental protection ratings. The WLCA2-LD-N maintains active product status with RoHS compliance and REACH unaffected designation, ensuring regulatory alignment for current applications.

The WLCA2-LD-N provides increased current handling capacity (10A AC / 6A DC versus 100mA) while maintaining voltage compatibility. This enhanced rating accommodates higher-load applications within the same form factor and interface specifications. Mechanical life is extended to 15,000,000 cycles, supporting extended service intervals in high-cycle applications.

Frequently Asked Questions (FAQ)

Q: Can the WLCA2-LD-N directly replace the WL01H2-LD in existing assemblies?

A: Yes. Both components share identical mounting type (chassis mount), termination style (screw terminal), actuator configuration (side rotary roller), and environmental protection (IP67). Physical and electrical interfaces are compatible.

Q: What are the key differences between these components?

A: The primary differences are current rating capacity and product status. The WLCA2-LD-N supports 10A AC and 6A DC compared to 100mA for the WL01H2-LD. The WLCA2-LD-N is an active product with current certifications, while the WL01H2-LD is obsolete.

Q: Are there packaging differences?

A: The WL01H2-LD is supplied in standard packaging, while the WLCA2-LD-N is supplied in bulk packaging. This does not affect component functionality or interface compatibility.

Q: What compliance certifications apply to the substitute?

A: The WLCA2-LD-N is RoHS compliant and REACH unaffected. Both components carry EAR99 ECCN classification and 8536.50.9055 HTSUS code.

Q: Should circuit current requirements be re-evaluated during substitution?

A: The increased current rating of the WLCA2-LD-N does not require circuit modification for applications within the original 100mA specification. The component operates safely at lower current levels.
