Omron WL01CL Snap Action Switch - Equivalent & Substitute Parts

Part Overview

The Omron WL01CL is a snap action switch with SPDT (Double Pole/Double Make) circuit configuration, rated for 0.1A at 125V AC and 30V DC. This component features a side rotary actuator with adjustable rod, chassis mount termination via screw terminals, and IP67 ingress protection suitable for dust-tight and waterproof applications.

The WL01CL carries an Obsolete product status. Locating equivalent substitute parts is necessary to maintain system functionality and ensure continued availability for repair, replacement, and new design implementations where this switch type is specified.

Substitute Part Grouping Explanation

Substitution of the WL01CL is determined by strict alignment of the following electrical and mechanical parameters:

Critical Substitution Criteria:

Circuit configuration: SPDT (DB/DM) topology
Switch function: On-Momentary operation
Voltage rating: Minimum 125V AC and 30V DC
Actuator type: Side rotary with adjustable rod
Mounting interface: Chassis mount with screw terminals
Environmental sealing: IP67 ingress protection
Operating temperature range: -10°C to 80°C minimum

The Omron WLCL-N qualifies as a substitute part because it maintains identical circuit topology, actuator configuration, mounting method, termination style, ingress protection rating, and operating temperature range. Current rating differences (100mA vs. 10A AC / 6A DC) represent an upgrade in electrical capacity, making the WLCL-N suitable for applications requiring equal or lower current draw than the original specification.

Engineering Selection Recommendations

The WLCL-N is the qualified substitute for the obsolete WL01CL based on the following factors:

Electrical Compatibility: The WLCL-N maintains identical voltage ratings (125V AC / 30V DC) and exceeds the current capacity of the original part. Applications drawing 100mA or less operate within the WLCL-N specification envelope.

Mechanical and Environmental Compatibility: Both parts share identical actuator geometry (side rotary, adjustable rod), mounting interface (chassis mount), termination method (screw terminal), and environmental protection (IP67). Physical and electrical interfaces are directly compatible.

Product Status and Availability: The WL01CL is obsolete with no active manufacturing. The WLCL-N is an active product from the same manufacturer, ensuring long-term availability and supply chain continuity.

Compliance and Certification: The WLCL-N carries RoHS Compliant status, meeting modern regulatory requirements. Both parts share identical ECCN (EAR99) and HTSUS (8536.50.9055) classifications.

Frequently Asked Questions (FAQ)

Q: Can the WLCL-N directly replace the WL01CL in existing designs?

A: Yes. Both parts maintain identical circuit topology (SPDT), switch function (On-Momentary), actuator type (side rotary with adjustable rod), mounting configuration (chassis mount), termination style (screw terminal), and environmental rating (IP67). Physical and electrical interfaces are compatible. The WLCL-N operates within the same voltage range (125V AC / 30V DC) and temperature envelope (-10°C to 80°C).

Q: What is the difference in current rating between these parts?

A: The WL01CL is rated for 100mA at both AC and DC. The WLCL-N is rated for 10A AC and 6A DC. The WLCL-N provides higher current capacity. Applications requiring 100mA or less operate safely within WLCL-N specifications.

Q: Are there packaging differences between WL01CL and WLCL-N?

A: The WL01CL is supplied with standard packaging. The WLCL-N is supplied in bulk packaging. Both are suitable for component-level integration and assembly operations.

Q: How do the electrical life ratings compare?

A: The WL01CL specifies 1,000,000 electrical cycles. The WLCL-N specifies 750,000 electrical cycles. Both parts maintain 15,000,000 mechanical cycles. For applications requiring extended electrical cycle life, design margins should account for the WLCL-N specification.

Q: Is the WLCL-N RoHS compliant?

A: Yes. The WLCL-N carries RoHS Compliant status, meeting current environmental and regulatory requirements for electronic components.
