MPC3BWC LED Panel Indicator - Equivalent & Substitute Parts

Part Overview

The MPC3BWC is a panel-mount LED indicator manufactured by Bivar Inc., featuring a blue LED with clear lens transparency and 15mcd brightness rating. This product is classified as obsolete, necessitating the identification of compatible substitute components for continued system integration and procurement. The MPC3BWC operates at 4V with a maximum current of 25mA and is housed in a standard 3mm T-1 package with a 0.24" (6.10mm) round panel cutout.

Key Parameters

Substitute Part Grouping Explanation

Substitute relationships for the MPC3BWC are established based on the following compatibility criteria:

• Color and Wavelength Matching: Lamp and lens color must both be blue with peak wavelength of 430nm to maintain optical consistency
• Electrical Specifications: Voltage (4V) and current ratings (25mA) must be identical for direct circuit substitution
• Mechanical Compatibility: Lens size (3mm T-1), panel cutout dimensions (0.24" / 6.10mm round), and lens style (round with domed top) must match for panel integration
• Moisture Sensitivity: MSL rating of 1 (Unlimited) maintains equivalent environmental reliability

The MPC3BWD qualifies as a substitute under these parameters, with the following differences: lens transparency (diffused vs. clear), millicandela rating (10mcd vs. 15mcd), viewing angle (35° vs. 20°), and active product status (vs. obsolete).

Parameter Comparison

Engineering Selection Recommendations

The MPC3BWD is available as an active product with ROHS3 compliance and REACH compliance status, providing regulatory advantages over the obsolete MPC3BWC. Both components meet identical electrical specifications (4V, 25mA) and mechanical panel mounting requirements (0.24" round cutout, 3mm T-1 housing).

The substitution introduces three notable parameter differences: lens transparency (diffused vs. clear), brightness output (10mcd vs. 15mcd), and viewing angle (35° vs. 20°). These differences must be evaluated against specific application requirements. Additionally, the MPC3BWD features PC Pin termination in place of wire termination, requiring board-level connection modification.

Selection of the MPC3BWD is appropriate for applications where the wider viewing angle (35°) and diffused lens characteristics align with design intent, and where the reduced brightness output (10mcd) remains sufficient for the indicator function. Current product availability and active manufacturing status of the MPC3BWD support long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: What are the core compatibility requirements for substituting the MPC3BWC?

A: Substitutes must maintain identical voltage (4V) and current (25mA) ratings, matching blue lamp and lens color with 430nm wavelength, and identical mechanical specifications including 3mm T-1 lens size and 0.24" (6.10mm) round panel cutout.

Q: How does lens transparency affect substitutability?

A: The MPC3BWC features a clear lens providing direct light transmission, while the MPC3BWD offers a diffused lens that scatters light across a wider viewing angle (35° vs. 20°). These optical characteristics are interchangeable based on application visibility requirements, but they are not functionally equivalent for all applications.

Q: What is the impact of the 5mcd brightness difference?

A: The MPC3BWC provides 15mcd while the MPC3BWD provides 10mcd. The choice depends on visibility requirements in the intended application environment. The reduced output of the substitute must be evaluated against actual operating conditions.

Q: What connector changes are required when substituting the MPC3BWD?

A: The MPC3BWC uses wire termination while the MPC3BWD uses PC Pin termination. This requires modification of the board-level connection method and mounting hardware, introducing a mechanical assembly change.

Q: Are there regulatory differences between these components?

A: The MPC3BWD provides ROHS3 compliance and REACH compliance status, while regulatory documentation for the obsolete MPC3BWC is not provided. This may represent an advantage for applications subject to these regulatory frameworks.
