Omron A22R-FG-10M Pushbutton Switch - Equivalent & Substitute Parts

Part Overview

The Omron A22R-FG-10M is a panel-mount pushbutton switch with SPST-NO (Single Pole Single Throw - Normally Open) circuit configuration, rated for 10A at 120V AC. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and redesign applications. The A22R series represents an earlier generation of Omron's pushbutton switch portfolio, and equivalent models from current or compatible product lines provide direct functional replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the A22R-FG-10M is determined by strict alignment of the following critical parameters:

• Circuit Configuration: SPST-NO topology must be maintained
• Current Rating: Minimum 10A AC capability required
• Voltage Rating: Minimum 120V AC support required
• Mounting Interface: Panel mount, front configuration with 22.30mm circular cutout
• Actuator Geometry: Round, button, flush design for mechanical compatibility
• Termination: Screw terminal connection method
• Ingress Protection: IP65 minimum rating for environmental sealing

The A22NN-RNM-NGA-G100-NN qualifies as a direct functional substitute. This part maintains all critical electrical parameters while offering enhanced specifications in mechanical life (5,000,000 cycles versus 3,000,000), expanded voltage support (24V DC in addition to 120V AC), improved ingress protection (IP66 versus IP65), and extended operating temperature range (-25°C to 70°C versus -20°C to 60°C). The identical panel cutout dimension (22.30mm) and actuator configuration ensure mechanical interchangeability without panel modification.

Parameter Comparison

Engineering Selection Recommendations

The A22NN-RNM-NGA-G100-NN is the qualified substitute for the obsolete A22R-FG-10M. Both components share identical electrical ratings for the primary application voltage (120V AC, 10A) and mechanical interface specifications, ensuring direct replacement without circuit redesign or panel modification.

The A22NN series component offers measurable improvements in durability and environmental performance. The increased mechanical life rating (5,000,000 cycles) extends service intervals in high-cycle applications. The enhanced ingress protection rating (IP66 versus IP65) provides superior resistance to water ingress, beneficial in washdown or high-humidity environments. The extended operating temperature range accommodates broader deployment scenarios.

For applications requiring DC operation, the A22NN-RNM-NGA-G100-NN provides 24V DC capability, enabling use in dual-voltage systems where the original A22R-FG-10M was limited to AC operation.

Both components carry identical electrical life ratings (500,000 cycles) and share the same termination methodology, supporting straightforward installation procedures. The A22NN component's RoHS compliance status provides regulatory advantage for new equipment designs and systems subject to environmental directives.

Frequently Asked Questions (FAQ)

Q: Can the A22NN-RNM-NGA-G100-NN be installed in the same panel cutout as the A22R-FG-10M?

A: Yes. Both components feature identical 22.30mm circular panel cutout dimensions and front-mount configuration. No panel modification is required for mechanical installation.

Q: Are the electrical ratings identical between these two parts?

A: The AC ratings are identical: 10A at 120V. The A22NN-RNM-NGA-G100-NN adds 24V DC capability (8A), which the A22R-FG-10M does not provide. For AC-only applications at 120V, 10A, both parts are electrically equivalent.

Q: What is the difference in ingress protection between IP65 and IP66?

A: IP65 provides dust-tight and water-resistant protection against low-pressure water jets. IP66 extends this to high-pressure water jets. For applications involving direct water spray or washdown environments, IP66 offers enhanced protection.

Q: Does the substitute part require different wiring or termination methods?

A: No. Both components use screw terminal termination. Existing wiring connections transfer directly without modification.

Q: Why is the A22NN-RNM-NGA-G100-NN rated for 5,000,000 mechanical cycles versus 3,000,000 for the original part?

A: The A22NN series represents a later design generation with improved mechanical durability. This extended cycle rating reflects design enhancements in the contact mechanism and spring assembly, providing longer service life in repetitive switching applications.

Q: Is RoHS compliance a factor in selecting the substitute?

A: RoHS compliance is relevant for new equipment designs and systems subject to environmental regulations in specific markets. The A22NN-RNM-NGA-G100-NN's RoHS compliance status provides regulatory advantage. The original A22R-FG-10M's RoHS status is not specified in available documentation.

Q: Can the A22NN-RNM-NGA-G100-NN operate across the full temperature range of -25°C to 70°C in all applications?

A: The component is rated for operation across this temperature range. Application-specific performance should be verified based on circuit requirements and environmental conditions at deployment locations.
