Omron A22R-FW-M Configurable Switch Body Equivalent & Substitute Parts

Part Overview

The Omron A22R-FW-M is a configurable switch body designed for pushbutton applications with a round, non-illuminated actuator. This component serves as the base housing for momentary switch configurations and requires separate contact block(s) for complete functionality. The product is classified as obsolete, making identification of equivalent substitute parts essential for ongoing maintenance, repair, and system support applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the A22R-FW-M is determined by the following critical parameters:

• Panel Cutout Dimensions: 22.3mm (Round) — mechanical compatibility requirement
• Actuator Type: Pushbutton, Round — functional form factor
• Switch Type: Momentary — operational characteristic
• Illumination: Non-Illuminated — feature set
• Moisture Sensitivity Level: 1 (Unlimited) — environmental rating
• Contact Block Requirement: Modular design requiring separate contact blocks

The substitute part A22NZ-RNM-NWA meets all critical substitution criteria. While it belongs to the A22NN series rather than the A22R series, it maintains identical mechanical mounting dimensions, actuator configuration, switch operation type, and environmental specifications. Both parts function as configurable switch bodies within the Omron modular switch ecosystem and accept compatible contact block modules.

Parameter Comparison

Engineering Selection Recommendations

The A22NZ-RNM-NWA serves as a direct functional equivalent to the A22R-FW-M for applications requiring a configurable switch body with round, non-illuminated pushbutton actuator and 22.3mm panel mounting. Both parts are classified as obsolete products and carry identical export control (EAR99) and tariff classifications (HTSUS 8536.50.9065).

The substitute part is RoHS compliant, providing an additional environmental compliance advantage. Both components maintain the same mechanical interface, electrical characteristics through contact block modularity, and environmental ratings. Selection between these parts should be based on availability, packaging requirements (the substitute is available in bulk packaging), and inventory status within your supply chain.

Frequently Asked Questions (FAQ)

Q: Can the A22NZ-RNM-NWA directly replace the A22R-FW-M in existing installations?

A: Yes. Both parts share identical panel cutout dimensions (22.3mm round), actuator type (pushbutton, round), switch operation (momentary), and contact block interface. The mechanical and functional compatibility is complete.

Q: What is the significance of the series designation change from A22R to A22NN?

A: The series designation reflects Omron's product line organization. However, both series operate within the same modular switch ecosystem and accept compatible contact block modules. The series change does not affect substitution eligibility when all critical parameters align.

Q: Are there any compliance differences between these parts?

A: Both parts carry identical ECCN (EAR99) and HTSUS (8536.50.9065) classifications. The substitute part includes RoHS compliance certification, which the main part does not explicitly list.

Q: What role do contact blocks play in substitution compatibility?

A: Both the A22R-FW-M and A22NZ-RNM-NWA are configurable switch bodies that require separate contact block modules for electrical functionality. Contact block compatibility is determined by the modular interface design, which remains consistent across both parts.

Q: Does packaging affect substitution suitability?

A: Packaging format (bulk versus other configurations) does not affect electrical or mechanical compatibility. Packaging selection should be based on procurement requirements and inventory management practices.

Q: Why are both parts classified as obsolete?

A: Obsolete status indicates these products are no longer in active production. Substitute identification ensures continued availability for maintenance and repair of existing systems utilizing these components.
