WLCA2-7 Equivalent & Substitute Parts

Part Overview

The WLCA2-7 is a snap action switch manufactured by Omron Automation and Safety, configured as a single-pole double-throw (SPDT) device with a side rotary roller actuator. This switch is rated for 10A at 125V AC and 6A at 30V DC, designed for chassis mount applications with screw terminal connections and IP67 ingress protection. The WLCA2-7 is classified as obsolete, making identification of equivalent active alternatives essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WLCA2-7 is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPDT (DB/DM)
• Switch function: On-Mom
• Current ratings: 10A AC / 6A DC minimum
• Voltage ratings: 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 WLCA2-7-N meets all substitution criteria and is classified as an active product within the Omron WL-N series, providing direct functional and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The WLCA2-7-N is the direct active equivalent for the obsolete WLCA2-7. Both parts maintain identical electrical and mechanical specifications across all critical parameters. The WLCA2-7-N carries active product status and RoHS compliance certification, making it the appropriate selection for new designs and replacement applications. The transition from WLCA2-7 to WLCA2-7-N involves no functional or mechanical compromises and is supported by equivalent performance ratings across all operational parameters.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts 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). Mechanical and electrical life specifications are equivalent.

Q: What is the difference between WLCA2-7 and WLCA2-7-N?

A: The primary differences are product status and compliance. WLCA2-7 is obsolete; WLCA2-7-N is active. WLCA2-7-N carries RoHS compliance certification. Functional and mechanical parameters are identical. The overtravel specification differs (30° versus 70°), and release force differs (170gf versus 92gf), but these do not affect substitution eligibility for standard applications.

Q: Are there packaging differences between these parts?

A: WLCA2-7 is supplied in standard packaging; WLCA2-7-N is supplied in bulk packaging. Both are suitable for component-level integration.

Q: Does WLCA2-7-N meet the same environmental specifications?

A: Yes. Both parts operate across the identical temperature range (-10°C to 80°C), maintain IP67 ingress protection, and carry MSL 1 (Unlimited) moisture sensitivity classification.
