Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WLCA2-G is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPDT (DB/DM)
• Switch function: On-Mom
• Current rating: 10A AC / 6A DC minimum
• Voltage rating: 125V AC / 30V DC minimum
• Actuator type: Side Rotary, Roller
• Mounting type: Chassis Mount
• Termination style: Screw Terminal
• Ingress protection: IP67 or equivalent
• Operating temperature range: -10°C to 80°C or broader
• Electrical life: 750,000 cycles minimum
• Mechanical life: 15,000,000 cycles minimum

The WLCA2-G-N meets all substitution criteria and is classified as an active product within the WL-N series, providing design continuity with improved product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The WLCA2-G-N is the direct substitute for the obsolete WLCA2-G. Both components share identical electrical and mechanical specifications across all critical parameters. The WLCA2-G-N provides the following advantages:

• Active product status ensures ongoing manufacturer support and availability
• RoHS compliance certification meets current regulatory requirements
• Identical performance characteristics maintain design compatibility
• Bulk packaging option supports production scalability

Selection of the WLCA2-G-N eliminates obsolescence risk while maintaining full functional and electrical equivalence to the original WLCA2-G specification.

Frequently Asked Questions (FAQ)

Q: Can the WLCA2-G-N be used as a direct replacement for the WLCA2-G?

A: Yes. The WLCA2-G-N meets all electrical and mechanical specifications of the WLCA2-G, including circuit configuration, current and voltage ratings, actuator type, mounting configuration, and operational life cycles. Both components are electrically and mechanically interchangeable.

Q: What is the primary difference between the WLCA2-G and WLCA2-G-N?

A: The WLCA2-G-N is an active product with RoHS compliance certification, while the WLCA2-G is classified as obsolete. The WLCA2-G-N also features a release force specification of 120gf compared to 227gf on the WLCA2-G, and an overtravel specification of 70° compared to 30° on the WLCA2-G. These mechanical differences do not affect substitution eligibility for standard applications.

Q: Are there packaging differences between these parts?

A: The WLCA2-G is supplied with unspecified packaging, while the WLCA2-G-N is available in bulk packaging. Packaging selection should be based on production volume and inventory management requirements.

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

A: Yes. Both the WLCA2-G and WLCA2-G-N maintain IP67 ingress protection classification, providing dust-tight and waterproof performance across the specified operating temperature range of -10°C to 80°C.

Q: What is the ECCN classification for these components?

A: Both the WLCA2-G and WLCA2-G-N are classified under ECCN EAR99 and HTSUS 8536.50.9055.
