WLH2-1 Equivalent & Substitute Parts

Part Overview

The WLH2-1 is a snap action SPDT switch manufactured by Omron Automation and Safety, designed for chassis mount applications requiring 10A AC / 6A DC switching capacity at 125V AC / 30V DC. The switch features a side rotary roller actuator with screw terminal connections and IP67 ingress protection. The WLH2-1 is classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

The WLCA2-N qualifies as a direct substitute for the WLH2-1 based on the following critical parameters:

• Circuit Configuration: Both parts maintain SPDT (DB/DM) topology
• Switch Function: Both operate as On-Momentary switches
• Current Rating: Both support 10A AC / 6A DC
• Voltage Rating: Both rated for 125V AC / 30V DC
• Actuator Type: Both feature side rotary roller actuation
• Mounting Type: Both are chassis mount
• Termination Style: Both use screw terminals
• Ingress Protection: Both provide IP67 protection
• Operating Temperature: Both operate across -10°C to 80°C

The WLCA2-N represents an active product from the WL-N series, providing a viable replacement path for the obsolete WLH2-1.

Parameter Comparison

Engineering Selection Recommendations

The WLCA2-N is the appropriate substitute for the obsolete WLH2-1 in applications requiring equivalent electrical and mechanical performance. The WLCA2-N maintains all critical functional parameters while offering enhanced mechanical durability (15,000,000 cycles versus 10,000,000 cycles) and improved regulatory compliance through ROHS3 certification and REACH unaffected status. The WLCA2-N's active product status ensures long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the WLCA2-N directly replace the WLH2-1 in existing applications?

A: Yes. Both parts share identical circuit configuration (SPDT), switch function (On-Momentary), 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 life and operating force differences do not prevent substitution in standard applications.

Q: What are the differences between WLH2-1 and WLCA2-N?

A: The WLCA2-N offers extended mechanical life (15,000,000 cycles versus 10,000,000 cycles), higher operating force (1360gf versus 1000gf), increased release force (120gf versus 100gf), and greater overtravel (70° versus 55°). The WLCA2-N is ROHS3 compliant and REACH unaffected, whereas the WLH2-1 has undefined REACH status. The WLCA2-N is an active product; the WLH2-1 is obsolete.

Q: Are there packaging differences between these parts?

A: The WLH2-1 is packaged individually; the WLCA2-N is supplied in bulk packaging. Verify bulk packaging compatibility with your procurement and assembly processes.

Q: Do both parts meet the same regulatory standards?

A: Both parts carry EAR99 ECCN classification. The WLCA2-N provides superior regulatory documentation with ROHS3 compliance and REACH unaffected status, whereas the WLH2-1 has vendor-undefined REACH status.
