WLRCA2 Equivalent & Substitute Parts

Part Overview

The WLRCA2 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 side rotary actuation without lever and screw terminal connections. The product is classified as obsolete, making identification of equivalent and substitute parts essential for system maintenance and component replacement in existing installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the WLRCA2 is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT DB/DM topology)
• Switch function (On-Momentary operation)
• Current and voltage ratings (10A AC / 6A DC; 125V AC / 30V DC)
• Actuator type (Side Rotary - No Lever)
• Mounting interface (Chassis Mount)
• Termination method (Screw Terminal)
• Environmental protection (IP67 rating)
• Operating temperature range (-10°C to 80°C)
• Electrical and mechanical life specifications

The WLRCA2-N qualifies as a direct substitute based on complete alignment with all specified parameters. The primary distinction is product status: WLRCA2 is obsolete while WLRCA2-N is active, and packaging differs (standard versus bulk).

Parameter Comparison

Engineering Selection Recommendations

The WLRCA2-N is the direct substitute for the obsolete WLRCA2. Both components share identical electrical specifications, mechanical interfaces, and environmental ratings. The WLRCA2-N offers the advantage of active product status, ensuring continued availability and manufacturer support. Additionally, WLRCA2-N carries RoHS compliance certification and defined REACH status, providing regulatory clarity for new system designs and compliance documentation.

For applications requiring the WLRCA2, transition to WLRCA2-N without modification to circuit design, mounting hardware, or termination connections.

Frequently Asked Questions (FAQ)

Q: Can WLRCA2-N replace WLRCA2 in existing installations?

A: Yes. The WLRCA2-N is electrically and mechanically equivalent to WLRCA2. All electrical ratings, switching characteristics, mounting interfaces, and environmental specifications are identical. No circuit modifications or hardware changes are required.

Q: What is the primary difference between WLRCA2 and WLRCA2-N?

A: WLRCA2 is classified as obsolete, while WLRCA2-N is an active product. WLRCA2-N also includes RoHS compliance certification and defined REACH status. Packaging differs: WLRCA2 uses standard packaging while WLRCA2-N is supplied in bulk.

Q: Are there any compliance differences between these parts?

A: WLRCA2-N is RoHS compliant with REACH affected status clearly defined. WLRCA2 has vendor-undefined REACH status and unspecified RoHS compliance. For new designs or systems requiring regulatory documentation, WLRCA2-N is the appropriate selection.

Q: What electrical parameters must match for substitution?

A: Current rating (10A AC / 6A DC), voltage rating (125V AC / 30V DC), circuit configuration (SPDT), and switch function (On-Momentary) must remain constant. The WLRCA2-N maintains all these specifications.

Q: Are the mechanical interfaces identical?

A: Yes. Both parts feature chassis mount installation, side rotary actuation without lever, and screw terminal connections. Physical mounting and electrical connection points are identical.

Q: What is the IP67 rating significance?

A: IP67 indicates dust-tight and waterproof protection. Both WLRCA2 and WLRCA2-N meet this specification, suitable for applications requiring environmental sealing.
