WLH2-TC Equivalent & Substitute Parts

Part Overview

The WLH2-TC is a snap action switch manufactured by Omron Automation and Safety, configured as a single-pole double-throw (SPDT) device with chassis mount installation. This switch is rated for 10A at 125V AC and 6A at 30V DC, featuring a side rotary roller actuator with screw terminal connections and IP67 ingress protection. The WLH2-TC is classified as obsolete, making identification of functionally equivalent active alternatives necessary for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

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

Circuit configuration remains SPDT (DB/DM), maintaining identical electrical switching topology. Current and voltage ratings are identical: 10A at 125V AC and 6A at 30V DC. Actuator type, mounting configuration, termination style, and ingress protection rating are all preserved. Operating temperature range, moisture sensitivity level, and electrical life specifications match exactly.

The WLCA2-TC-N represents an active product within the WL-N series evolution, providing continued availability where the WLH2-TC is no longer manufactured. Mechanical life is enhanced to 15,000,000 cycles compared to the original 10,000,000 cycles, and RoHS compliance is confirmed for the substitute part.

Parameter Comparison

Engineering Selection Recommendations

The WLH2-TC is classified as obsolete and no longer available from the manufacturer. The WLCA2-TC-N is the active equivalent within the Omron WL-N series, maintaining all critical electrical and mechanical specifications required for direct substitution.

The WLCA2-TC-N carries RoHS compliance certification, meeting current regulatory requirements for electronic component manufacturing and distribution. This compliance status provides assurance for applications subject to environmental and hazardous substance restrictions.

Selection of the WLCA2-TC-N for replacement applications is based on functional equivalence across all provided parameters. The enhanced mechanical life rating of 15,000,000 cycles represents an improvement over the original specification without introducing compatibility concerns.

Frequently Asked Questions (FAQ)

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

A: Yes. The WLCA2-TC-N maintains identical electrical ratings (10A at 125V AC, 6A at 30V DC), circuit configuration (SPDT), actuator type (side rotary roller), mounting method (chassis mount), and termination style (screw terminal). All critical functional parameters match the original specification.

Q: What is the difference in mechanical life between these parts?

A: The WLH2-TC is rated for 10,000,000 mechanical cycles, while the WLCA2-TC-N is rated for 15,000,000 mechanical cycles. This represents an enhancement in the substitute part without affecting compatibility.

Q: Does the WLCA2-TC-N meet current regulatory requirements?

A: Yes. The WLCA2-TC-N is RoHS compliant, meeting current environmental and hazardous substance restrictions applicable to electronic components.

Q: Are there any differences in operating force or travel specifications?

A: Operating force and travel specifications differ between the parts. The WLH2-TC specifies 1000gf operating force with 15° pretravel, 12° differential travel, and 55° overtravel. The WLCA2-TC-N specifies 1360gf operating force with 15° pretravel, 12° differential travel, and 70° overtravel. These differences do not affect functional substitution for applications where the original WLH2-TC was specified.

Q: What packaging options are available?

A: The WLH2-TC was supplied in standard packaging. The WLCA2-TC-N is available in bulk packaging format.
