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

Part Overview

The Omron A22R-FA-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 blocks for operation. The product is currently obsolete, making identification of compatible substitute parts essential for maintenance, repair, and legacy system support. Substitute parts must maintain identical mechanical fit, electrical interface compatibility, and functional characteristics to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the A22R-FA-M are identified based on the following critical parameters that determine functional and mechanical compatibility:

• Panel cutout dimensions (22.3mm round) ensure physical fit in existing installations
• Actuator type (pushbutton, round) maintains operational interface consistency
• Illumination status (non-illuminated) confirms functional equivalence
• Switch type (momentary) preserves electrical behavior
• Contact block interface compatibility allows use of existing or equivalent contact modules
• Moisture sensitivity level (MSL 1) indicates equivalent environmental protection

The identified substitute part A22NZ-RNM-NAA belongs to the A22NN series and maintains all critical parameters necessary for direct substitution in applications where the A22R-FA-M is specified.

Parameter Comparison

Engineering Selection Recommendations

The A22NZ-RNM-NAA serves as a direct substitute for the obsolete A22R-FA-M based on complete parameter alignment across all critical mechanical and electrical specifications. Both components share identical panel cutout dimensions, actuator configuration, and contact block interface requirements. The substitute part maintains equivalent export compliance (EAR99) and tariff classification (HTSUS 8536.50.9065), confirming regulatory equivalence. The A22NZ-RNM-NAA is available in bulk packaging with higher inventory levels (1035 pcs) compared to the original part, supporting procurement for legacy system maintenance and replacement applications.

Frequently Asked Questions (FAQ)

Q: Can the A22NZ-RNM-NAA be used as a direct replacement for the A22R-FA-M?

A: Yes. Both parts share identical panel cutout dimensions (22.3mm round), actuator type (pushbutton, round), illumination status (non-illuminated), switch type (momentary), and contact block interface requirements. These parameters define mechanical and functional compatibility for direct substitution.

Q: What is the difference between the A22R series and A22NN series?

A: The A22R-FA-M belongs to the A22R series, while the substitute A22NZ-RNM-NAA belongs to the A22NN series. Both series are Omron configurable switch body products with identical specifications for this application. Series designation reflects internal product line organization but does not affect compatibility when all functional parameters match.

Q: Does packaging type affect compatibility?

A: Packaging type (tray vs. bulk) does not affect component functionality or mechanical fit. The A22R-FA-M is supplied in tray packaging, while the A22NZ-RNM-NAA is supplied in bulk packaging. Selection between these options depends on procurement quantity and handling requirements, not technical compatibility.

Q: Are contact blocks interchangeable between these parts?

A: Yes. Both the A22R-FA-M and A22NZ-RNM-NAA require contact blocks and share identical contact block interface specifications. Existing contact blocks designed for the A22R-FA-M are compatible with the A22NZ-RNM-NAA.

Q: What does MSL 1 (Unlimited) indicate?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. Both the main part and substitute share this classification.
