Omron WLRG2-N Equivalent & Substitute Parts

Part Overview

The Omron WLRG2-N is a snap action SPDT switch rated for 5A at 125V AC with chassis mount configuration and screw terminal termination. This component features IP67 ingress protection and is designed for applications requiring reliable switching with high electrical and mechanical cycle life. The WLRG2-N is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WLRG2-N is determined by the following critical parameters:

• Circuit configuration must be SPDT (DB/DM) to maintain electrical functionality
• Actuator type must be Side Rotary - No Lever for mechanical compatibility
• Mounting type must be Chassis Mount for installation compatibility
• Termination style must be Screw Terminal for connection compatibility
• Ingress protection must be IP67 or equivalent for environmental sealing
• Operating temperature range must encompass or exceed -10°C to 80°C
• Current and voltage ratings must meet or exceed application requirements

The WLR01G2 shares identical circuit configuration, actuator type, mounting method, termination style, and ingress protection rating. However, the WLR01G2 operates at reduced current capacity (100mA AC/DC versus 5A AC/400mA DC) and lower DC voltage rating (30V DC versus 125V DC), making it suitable only for applications with lower power requirements.

Parameter Comparison

Engineering Selection Recommendations

The WLR01G2 is an active product from Omron Automation and Safety and maintains mechanical and environmental compatibility with the obsolete WLRG2-N through identical circuit configuration, actuator design, mounting method, termination style, and IP67 ingress protection rating.

Selection of the WLR01G2 as a substitute is contingent upon application current and voltage requirements. The WLR01G2 is suitable for applications operating at 100mA or less (AC/DC) and 30V DC maximum. Applications requiring the full 5A AC or 400mA DC capacity of the original WLRG2-N, or DC voltages exceeding 30V, cannot use the WLR01G2 without circuit redesign.

The WLR01G2 demonstrates superior electrical cycle life (750,000 cycles versus 500,000 cycles), providing extended operational durability in equivalent mechanical and environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can the WLR01G2 directly replace the WLRG2-N in all applications?

A: Direct replacement is limited to applications with current requirements of 100mA or less and DC voltage requirements not exceeding 30V. The WLR01G2 cannot support the full 5A AC or 400mA DC rating of the WLRG2-N.

Q: Are the mechanical mounting interfaces identical between these parts?

A: Yes. Both parts feature chassis mount configuration with side rotary actuator (no lever) and screw terminal termination, ensuring mechanical compatibility in equivalent mounting locations.

Q: What is the environmental sealing capability of the WLR01G2?

A: The WLR01G2 maintains IP67 ingress protection rating, identical to the WLRG2-N, providing dust-tight and waterproof sealing for equivalent environmental applications.

Q: Does the WLR01G2 operate across the same temperature range?

A: Yes. Both parts operate across -10°C to 80°C, ensuring thermal compatibility in equivalent operating environments.

Q: What is the product availability status of the WLR01G2?

A: The WLR01G2 is classified as active product status with current manufacturing and distribution availability, unlike the obsolete WLRG2-N.
