WLH2-LEAS Equivalent & Substitute Parts

Part Overview

The WLH2-LEAS is an Omron Automation and Safety snap action switch with SPDT (Single Pole Double Throw) configuration, rated for 10A at 125V AC and 6A at 30V DC. This chassis-mounted switch features a side rotary roller actuator with screw terminal connections and IP67 ingress protection. The product is currently obsolete, making identification of equivalent substitute parts essential for maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

The WLCA2-LEAS-N qualifies as a substitute for the WLH2-LEAS based on the following critical parameters:

Electrical Compatibility:

• Identical SPDT circuit configuration
• Matching current ratings: 10A AC, 6A DC
• Matching voltage ratings: 125V AC, 30V DC
• Identical switch function: On-Mom

Mechanical Compatibility:

• Identical actuator type: Side Rotary, Roller
• Identical mounting type: Chassis Mount
• Identical termination style: Screw Terminal
• Identical ingress protection: IP67

Environmental Compatibility:

• Identical operating temperature range: -10°C to 80°C
• Identical moisture sensitivity level: MSL 1 (Unlimited)

Operational Differences (Non-Critical): The WLCA2-LEAS-N exhibits higher operating force (1360gf vs. 1000gf), higher release force (120gf vs. 100gf), greater overtravel (70° vs. 55°), and extended mechanical life (15,000,000 cycles vs. 10,000,000 cycles). These differences represent performance enhancements that do not prevent substitution.

Parameter Comparison

Engineering Selection Recommendations

The WLCA2-LEAS-N is the direct substitute for the obsolete WLH2-LEAS. Both components share identical electrical ratings, circuit configuration, mechanical mounting, and environmental specifications. The WLCA2-LEAS-N is currently in active production status, ensuring availability for replacement applications.

The WLCA2-LEAS-N provides enhanced mechanical durability through increased operating force, higher release force, and extended mechanical life. These characteristics represent performance improvements that maintain full backward compatibility with systems originally designed for the WLH2-LEAS.

The WLCA2-LEAS-N carries RoHS non-compliant status, consistent with legacy Omron WL series switch design. Selection should account for application-specific compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the WLCA2-LEAS-N directly replace the WLH2-LEAS in existing installations?

A: Yes. The WLCA2-LEAS-N maintains identical electrical ratings (10A at 125V AC, 6A at 30V DC), SPDT circuit configuration, actuator type, mounting method, and termination style. Mechanical and electrical performance characteristics are compatible with the original WLH2-LEAS specification.

Q: What are the differences between the WLH2-LEAS and WLCA2-LEAS-N?

A: The primary differences are product status and mechanical performance. The WLH2-LEAS is obsolete; the WLCA2-LEAS-N is active production. The WLCA2-LEAS-N features higher operating force (1360gf vs. 1000gf), higher release force (120gf vs. 100gf), greater overtravel (70° vs. 55°), and extended mechanical life (15,000,000 vs. 10,000,000 cycles).

Q: Are there packaging differences between these parts?

A: The WLH2-LEAS is supplied with standard packaging. The WLCA2-LEAS-N is supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: What is the RoHS compliance status of the WLCA2-LEAS-N?

A: The WLCA2-LEAS-N is RoHS non-compliant. Applications requiring RoHS compliance must evaluate alternative component families or obtain specific compliance documentation from Omron Automation and Safety.

Q: Are both parts suitable for IP67 applications?

A: Yes. Both the WLH2-LEAS and WLCA2-LEAS-N carry IP67 ingress protection rating (dust tight, waterproof) and are suitable for sealed enclosure applications within the specified operating temperature range of -10°C to 80°C.
