WLCL-TH Snap Action Switch - Equivalent & Substitute Parts

Part Overview

The WLCL-TH is an Omron Automation and Safety snap action switch with SPDT (DB/DM) circuit configuration, rated for 10A at 125V AC and 6A at 30V DC. This component is classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and component procurement. The WLCL-TH-N represents the active production equivalent within the WL series family.

Key Parameters

Substitute Part Grouping Explanation

The WLCL-TH-N qualifies as a direct substitute based on the following critical parameters:

• Identical circuit configuration (SPDT DB/DM)
• Identical switch function (On-Momentary)
• Identical current and voltage ratings (10A/125V AC, 6A/30V DC)
• Identical actuator type (Side Rotary, Adjustable Rod)
• Identical mounting type (Chassis Mount)
• Identical termination style (Screw Terminal)
• Identical ingress protection rating (IP67)
• Identical operating temperature range (5°C to 120°C)
• Identical electrical and mechanical life specifications

The WLCL-TH-N is the active production variant of the obsolete WLCL-TH, manufactured by the same supplier within the WL series product line.

Parameter Comparison

Engineering Selection Recommendations

The WLCL-TH-N is the recommended substitute for the obsolete WLCL-TH. Both components share identical electrical and mechanical specifications across all critical parameters that determine functional compatibility. The WLCL-TH-N offers the additional advantage of active production status, ensuring long-term availability and supply chain continuity.

The WLCL-TH-N carries RoHS Compliant certification and REACH Unaffected status, providing enhanced regulatory compliance compared to the original part. The minor differences in release force (27gf versus 28gf) and overtravel (70° versus 30°) do not affect the core switching function or electrical performance within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can WLCL-TH-N be used as a direct replacement for WLCL-TH in existing applications?

A: Yes. The WLCL-TH-N maintains identical electrical ratings (10A/125V AC, 6A/30V DC), circuit configuration (SPDT), actuator type (Side Rotary, Adjustable Rod), mounting type (Chassis Mount), and termination style (Screw Terminal). All critical functional parameters are equivalent.

Q: What are the differences between WLCL-TH and WLCL-TH-N?

A: The primary differences are product status (obsolete versus active), series designation (WL versus WL-N), regulatory compliance (WLCL-TH-N is RoHS Compliant and REACH Unaffected), release force (27gf versus 28gf), and overtravel specification (70° versus 30°). These differences do not affect electrical or mechanical compatibility.

Q: Are there packaging differences between these parts?

A: The WLCL-TH-N is supplied in bulk packaging, while the WLCL-TH packaging specification is not defined. Confirm packaging requirements with your procurement process.

Q: What is the significance of the overtravel difference?

A: Overtravel is the additional distance the actuator travels beyond the switching point. The WLCL-TH-N has 70° overtravel compared to 30° for the WLCL-TH. This does not affect the switching function or electrical performance within the specified operating parameters.

Q: Is the WLCL-TH-N suitable for new designs?

A: Yes. The WLCL-TH-N is an active production component with RoHS Compliant and REACH Unaffected certifications, making it suitable for new designs and long-term procurement planning.
