Key Parameters

Substitute Part Grouping Explanation

The M22N-BC-TWA-WD qualifies as a substitute for the M22R-EW-T1 based on the following alignment of critical parameters:

Mechanical Compatibility: Both components feature identical panel cutout shapes (round) and compatible cutout dimensions (0.88" / 22.35mm vs. 22.30mm), enabling direct panel mounting without modification.

Functional Equivalence: Both are LED panel indicators with white lamp color and round flat-top lens styling, maintaining consistent visual appearance and operational function.

Electrical Compatibility: The M22N-BC-TWA-WD operates at 110V AC, which falls within the acceptable operating range for applications designed for 120V AC systems. The 2mA current specification provides defined load characteristics.

Environmental Protection: The M22N-BC-TWA-WD provides enhanced ingress protection (IP66, NEMA 4X, 13) compared to the original IP65 rating, ensuring superior sealing in demanding environments.

Product Availability: The M22N-BC-TWA-WD is classified as active with 1140 units in stock, providing reliable supply continuity for the obsolete M22R-EW-T1.

Parameter Comparison

Engineering Selection Recommendations

The M22N-BC-TWA-WD serves as the direct substitute for the obsolete M22R-EW-T1. Selection is based on:

Mechanical Fit: Panel cutout dimensions are compatible within manufacturing tolerances (22.35mm vs. 22.30mm), permitting direct installation in existing panel openings.

Electrical Operation: The 110V AC rating of the substitute is suitable for 120V AC circuits, as the 10V differential remains within acceptable tolerance for LED indicator operation.

Compliance Status: The M22N-BC-TWA-WD holds ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The original M22R-EW-T1 carries EAR99 classification.

Supply Continuity: With active product status and 1140 units in inventory, the M22N-BC-TWA-WD provides assured availability for replacement and new applications.

Frequently Asked Questions (FAQ)

Q: Can the M22N-BC-TWA-WD directly replace the M22R-EW-T1 in existing installations?

A: Yes. Both components share identical panel cutout shapes and compatible dimensions (0.88" / 22.30-22.35mm), enabling direct panel mounting without mechanical modification.

Q: What is the voltage compatibility between 120V and 110V ratings?

A: The M22N-BC-TWA-WD operates at 110V AC, which is acceptable for 120V AC applications. The 10V differential is within standard tolerance for LED indicator circuits.

Q: Does the substitute offer improved environmental protection?

A: Yes. The M22N-BC-TWA-WD provides IP66, NEMA 4X, and 13 ratings, exceeding the original IP65 specification for enhanced sealing in harsh environments.

Q: What is the packaging difference between these components?

A: The M22R-EW-T1 is supplied with standard packaging, while the M22N-BC-TWA-WD is available in bulk packaging format.

Q: Are there regulatory compliance differences?

A: The M22N-BC-TWA-WD includes ROHS3 compliance and REACH unaffected status, meeting current environmental regulations. Both components carry EAR99 export classification.

Q: Is the current specification critical for substitution?

A: The M22N-BC-TWA-WD specifies 2mA current draw. Verify that the circuit design accommodates this defined load characteristic for proper operation.
