Omron A22L-GR Configurable Switch Body Pushbutton Equivalent & Substitute Parts

Part Overview

The Omron A22L-GR is a configurable switch body component designed for pushbutton applications with round illuminated actuators in red. This part functions as the base housing assembly for modular switch construction, requiring separate contact blocks and illumination sources for complete operation. The A22L-GR is classified as obsolete, making identification of active equivalent parts essential for ongoing procurement and system maintenance. Substitute parts must maintain identical panel cutout dimensions, illumination type, and actuator geometry to ensure direct mechanical and electrical compatibility.

Key Parameters

Substitute Part Grouping Explanation

The A22NZ-BGM-TRA qualifies as a direct substitute based on the following critical parameters:

• Panel Cutout Dimensions: Both parts require 22.3mm round cutout, ensuring mechanical fit without modification
• Illumination Type: Both feature illuminated red actuators, maintaining visual consistency and functional equivalence
• Actuator Type: Both utilize round pushbutton actuators with identical engagement geometry
• Manufacturer Compatibility: Both are Omron products within the A22 family (A22L-GR from A22 series; A22NZ-BGM-TRA from A22NL series), confirming design lineage and modular compatibility
• RoHS Compliance: Both meet RoHS requirements, supporting equivalent environmental and regulatory standing
• MSL Rating: Both carry MSL 1 (Unlimited), indicating identical moisture handling characteristics

The A22NZ-BGM-TRA represents an active product status upgrade from the obsolete A22L-GR, with the primary functional difference being the addition of momentary-type operation specification in the newer variant.

Engineering Selection Recommendations

The A22NZ-BGM-TRA is the appropriate substitute for the obsolete A22L-GR based on the following engineering criteria:

• Product Status Alignment: The A22NZ-BGM-TRA carries active product status, ensuring continued manufacturer support, availability, and compliance with current regulatory standards
• Regulatory Compliance: Both parts maintain RoHS compliance and identical MSL ratings, confirming equivalent environmental qualification
• Mechanical Compatibility: Identical panel cutout dimensions (22.3mm round) and actuator geometry guarantee direct mechanical substitution without panel modification or mechanical redesign
• Functional Equivalence: Matching illumination type (red) and illuminated pushbutton configuration preserve system visual feedback and operational characteristics
• Modular Architecture: Both parts function within the Omron A22 family modular switch ecosystem, supporting the same contact block and illumination source interfaces

Selection of the A22NZ-BGM-TRA eliminates obsolescence risk while maintaining full compatibility with existing mechanical and electrical system requirements.

Frequently Asked Questions (FAQ)

Q: Can the A22NZ-BGM-TRA be used as a direct replacement for the A22L-GR without any modifications?

A: Yes. Both parts share identical panel cutout dimensions (22.3mm round), illumination type (red), and actuator geometry. No mechanical or electrical modifications are required for substitution.

Q: What is the primary difference between the A22L-GR and A22NZ-BGM-TRA?

A: The A22L-GR is obsolete, while the A22NZ-BGM-TRA is an active product. The A22NZ-BGM-TRA explicitly specifies momentary-type operation. Both maintain identical mechanical and environmental specifications.

Q: Are there any compatibility concerns with contact blocks or illumination sources?

A: Both parts function within the Omron A22 family modular architecture and require separate contact blocks and illumination sources. Existing contact block and illumination source selections remain compatible with the substitute part.

Q: Does the packaging difference (unspecified for A22L-GR versus bulk for A22NZ-BGM-TRA) affect compatibility?

A: Packaging format does not affect component compatibility or performance. Packaging differences relate only to procurement and logistics considerations.

Q: Are both parts RoHS compliant?

A: Yes. Both the A22L-GR and A22NZ-BGM-TRA are RoHS compliant with identical MSL 1 (Unlimited) ratings, confirming equivalent environmental qualification.
