Omron WLCA2-TC Snap Action Switch - Equivalent & Substitute Parts

Part Overview

The Omron WLCA2-TC is a snap action switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 10A at 125V AC and 6A at 30V DC. This component features a side rotary roller actuator, chassis mount configuration, and IP67 ingress protection suitable for industrial control applications. The WLCA2-TC is classified as obsolete, making identification of active equivalent parts essential for procurement and system continuity.

Key Parameters

Substitute Part Grouping Explanation

The WLCA2-TC-N qualifies as a direct substitute based on the following critical parameters that remain constant across both parts:

• Circuit configuration: SPDT (DB/DM)
• 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
• Ingress protection: IP67
• Operating temperature range: -40°C to 40°C
• Electrical life: 750,000 cycles
• Mechanical life: 15,000,000 cycles

The WLCA2-TC-N represents an active production variant within the Omron WL series, offering functional and electrical equivalence to the obsolete WLCA2-TC.

Parameter Comparison

Engineering Selection Recommendations

The WLCA2-TC-N is the direct active equivalent for the obsolete WLCA2-TC. Selection of the WLCA2-TC-N is supported by:

• Identical electrical ratings and circuit configuration
• Matching mechanical specifications for mounting and actuation
• Active product status ensuring ongoing availability and supply chain continuity
• RoHS compliance certification on the substitute part, meeting current regulatory requirements
• Equivalent ingress protection and environmental operating range

The minor variations in release force (227gf vs. 120gf) and overtravel (30° vs. 70°) do not affect functional equivalence for standard SPDT switching applications within the specified electrical and thermal parameters.

Frequently Asked Questions (FAQ)

Q: Can the WLCA2-TC-N directly replace the WLCA2-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), and mounting specifications (chassis mount with screw terminals). Both parts operate within the same temperature range and provide equivalent IP67 ingress protection.

Q: What is the significance of the product status difference?

A: The WLCA2-TC is classified as obsolete, indicating discontinued production. The WLCA2-TC-N is active, ensuring current manufacturing, documented supply availability, and ongoing technical support from Omron Automation and Safety.

Q: Are there packaging differences between these parts?

A: The WLCA2-TC packaging is unspecified in available documentation. The WLCA2-TC-N is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Does the RoHS compliance difference affect substitution?

A: The WLCA2-TC-N is RoHS compliant, while the WLCA2-TC status is vendor undefined. For applications subject to RoHS regulations or customer requirements, the WLCA2-TC-N provides documented compliance.

Q: What do the differences in release force and overtravel mean for compatibility?

A: Release force (227gf vs. 120gf) and overtravel (30° vs. 70°) are mechanical characteristics that affect actuator response. Both parts meet the same electrical switching requirements. Verify these mechanical parameters against your specific application requirements if actuator feel or response characteristics are critical to system performance.
