Omron A22-MR Configurable Switch Body Equivalent & Substitute Parts

Part Overview

The Omron A22-MR is a configurable switch body designed for pushbutton applications with a mushroom actuator in a non-illuminated configuration. This component serves as the mechanical housing and interface for contact blocks in the A22 series. The A22-MR is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing maintenance, repair, and new design applications where A22 series compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Omron A22-MR is determined by the following critical parameters that must remain constant:

• Panel cutout dimensions (22.3mm round)
• Actuator type (pushbutton, mushroom)
• Illumination status (non-illuminated)
• Mechanical interface compatibility with contact blocks
• RoHS and regulatory compliance status

The RAFI USA 1.30.246.512/0300 qualifies as a functional equivalent based on matching all critical mechanical and electrical parameters. Both components share identical panel cutout specifications, actuator configuration, and non-illuminated design. The RAFIX 22 QR series maintains mechanical compatibility with the same 22.3mm round panel interface required for A22 series applications.

Parameter Comparison

Engineering Selection Recommendations

The RAFI USA 1.30.246.512/0300 is a direct functional equivalent for the obsolete Omron A22-MR based on the following engineering criteria:

Mechanical compatibility is established through identical panel cutout dimensions (22.3mm round) and matching actuator configuration (pushbutton, mushroom, non-illuminated). Both components are designed to accept contact blocks and maintain the same interface specifications.

Regulatory compliance is satisfied by both components meeting RoHS requirements. The RAFI part carries ROHS3 compliance, which supersedes the RoHS compliance of the Omron part. Both components share identical ECCN (EAR99) and HTSUS classifications, confirming equivalent regulatory treatment.

Environmental specifications are identical, with both components rated at MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

The RAFI USA part maintains active product status, ensuring continued availability and supply chain reliability compared to the obsolete Omron component.

Frequently Asked Questions (FAQ)

Q: Can the RAFI USA 1.30.246.512/0300 directly replace the Omron A22-MR in existing applications?

A: Yes. Both components share identical mechanical specifications (22.3mm round panel cutout), actuator type (pushbutton, mushroom), and non-illuminated configuration. Contact block compatibility is maintained across both switch bodies.

Q: Are there differences in RoHS compliance between these parts?

A: Both parts meet RoHS requirements. The RAFI part carries ROHS3 compliance, which represents a current regulatory standard. The Omron part carries RoHS compliance. Both are acceptable for RoHS-regulated applications.

Q: What is the significance of the panel cutout dimension match?

A: The 22.3mm round panel cutout is the critical mechanical interface. Matching this dimension ensures the switch body fits existing panel installations without modification. This parameter is non-negotiable for direct substitution.

Q: Does the obsolete status of the Omron A22-MR affect substitution decisions?

A: Yes. The obsolete status of the Omron part makes the active RAFI USA alternative the appropriate choice for new procurement and long-term supply continuity. The RAFI part is actively manufactured and supported.

Q: Are there packaging differences between these components?

A: The Omron A22-MR packaging is not specified in available documentation. The RAFI USA 1.30.246.512/0300 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

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

A: Both switch bodies are configurable components that require contact blocks for electrical functionality. The mechanical interface for contact block attachment is identical between the Omron and RAFI parts, ensuring contact block interchangeability.
