Omron M22R-EG-24A LED Panel Indicator - Equivalent & Substitute Parts

Part Overview

The Omron M22R-EG-24A is a 24V LED panel indicator light with green diffused lens, rated for 8mA operation. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The M22R series has been superseded by the M22N series, which maintains core functional compatibility while offering enhanced ingress protection ratings and active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M22R-EG-24A is determined by the following critical parameters:

• Voltage rating: 24V AC/DC operation required
• Lamp and lens color: Green specification must be maintained
• Panel cutout dimensions: 0.88" (22.35mm) round cutout compatibility
• Lens style: Round with flat top configuration
• Ingress protection: Minimum IP65 rating

The M22N-BC-TGA-GC qualifies as a direct substitute based on matching voltage, color specification, panel cutout geometry, and lens style. While the M22N series introduces enhanced ingress protection (IP66, NEMA 4X, 13) and reduced current draw (5mA versus 8mA), these represent functional improvements rather than compatibility limitations. The mechanical and electrical interfaces remain compatible with the original M22R-EG-24A footprint and circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

The M22N-BC-TGA-GC is the qualified substitute for the obsolete M22R-EG-24A. Selection is supported by the following factors:

• Active product status ensures ongoing availability and supply chain continuity
• RoHS3 compliance and REACH unaffected status meet current regulatory requirements
• Enhanced ingress protection (IP66, NEMA 4X, 13) provides superior environmental sealing compared to the original IP65 rating
• Reduced current consumption (5mA versus 8mA) decreases power supply loading
• Mechanical compatibility with existing 22mm round panel cutouts eliminates redesign requirements
• Identical voltage rating and AC/DC operation maintain circuit compatibility

The primary difference—lens transparency change from diffused to clear—affects light diffusion characteristics. Applications requiring the specific diffused lens optical properties should be evaluated for visual performance impact before substitution.

Frequently Asked Questions (FAQ)

Q: Can the M22N-BC-TGA-GC directly replace the M22R-EG-24A in existing installations?

A: Yes. Both components share identical voltage ratings (24V AC/DC), panel cutout dimensions (0.88" round), and lens style (round with flat top). The mechanical and electrical interfaces are compatible. The M22N series offers improved ingress protection and lower current draw.

Q: What is the difference between diffused and clear lens transparency?

A: The M22R-EG-24A features a diffused lens that scatters light across a wider viewing angle, while the M22N-BC-TGA-GC has a clear lens that provides more focused light output. Applications sensitive to light distribution patterns should evaluate this difference.

Q: Does the reduced current draw (5mA versus 8mA) affect circuit design?

A: No. The lower current requirement of the M22N-BC-TGA-GC reduces power supply loading and heat generation. Existing circuits designed for 8mA operation will function correctly with the 5mA substitute without modification.

Q: Are there compliance differences between the two parts?

A: The M22N-BC-TGA-GC includes RoHS3 compliance and REACH unaffected status, meeting current regulatory standards. The M22R-EG-24A, as an obsolete part, may not carry current compliance certifications.

Q: What ingress protection improvement does the M22N-BC-TGA-GC provide?

A: The substitute offers IP66, NEMA 4X, and 13 ratings compared to the original IP65. This provides enhanced protection against water jets, corrosive environments, and oil immersion, suitable for more demanding industrial applications.

Q: Is the panel cutout dimension difference (22.35mm versus 22.30mm) significant?

A: No. The 0.05mm difference is within standard mechanical tolerance for round panel cutouts and does not affect installation compatibility.
