MPR5BWC LED Panel Indicator - Equivalent & Substitute Parts

Part Overview

The MPR5BWC is a panel-mounted LED indicator manufactured by Bivar Inc., designed for applications requiring a blue light output at 430nm wavelength with a 25° viewing angle. This part is classified as Obsolete, necessitating identification of equivalent substitutes for continued component sourcing and system integration. The MPR5BWC operates at 4V with a maximum current of 25mA and delivers 25mcd luminous intensity through a clear, domed lens.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MPR5BWC is determined by electrical and mechanical compatibility. The critical parameters for substitution are:

Electrical Compatibility: Voltage (4V), maximum current (25mA), and wavelength (430nm blue) must match to ensure proper circuit operation and intended luminous output color.

Mechanical Compatibility: Panel cutout shape (round), panel cutout dimensions (0.32"/8.13mm), and lens size (5mm, T-1 3/4) must align to permit direct mechanical installation without enclosure modification.

Optional Variations: Millicandela rating, lens transparency (clear vs. diffused), and viewing angle may vary within the MPR5 series while maintaining functional compatibility, provided the primary electrical and mechanical parameters remain constant.

The MPR5BWD is identified as a substitute part, sharing the MPR5 series designation, identical electrical ratings (4V, 25mA, 430nm), and compatible mechanical specifications (round cutout, 0.32", 5mm lens).

Parameter Comparison

Engineering Selection Recommendations

The MPR5BWD is the active production substitute for the obsolete MPR5BWC. Both parts maintain identical electrical specifications (4V, 25mA, 430nm) and are mechanically compatible for direct panel mounting. The MPR5BWD carries ROHS3 compliance and REACH Unaffected status, meeting modern regulatory requirements.

Differences in millicandela rating (25mcd vs. 15mcd) and viewing angle (25° vs. 40°) reflect design variations within the product family. The MPR5BWD's diffused lens and wider 40° viewing angle provide broader visibility distribution compared to the MPR5BWC's clear lens and focused 25° angle. Selection between these parameters depends on application-specific visibility and optical distribution requirements.

Frequently Asked Questions (FAQ)

Q: Is the MPR5BWD mechanically compatible with the MPR5BWC?

A: Yes. Both parts share identical panel cutout dimensions (0.32"/8.13mm round), lens size (5mm T-1 3/4), and mounting configuration, permitting direct substitution without enclosure modification.

Q: What are the electrical differences between MPR5BWC and MPR5BWD?

A: Electrical ratings are identical: 4V forward voltage, 25mA maximum current, and 430nm peak wavelength. The millicandela rating differs (25mcd vs. 15mcd), reflecting lens design and optical transparency variations.

Q: Why does the MPR5BWD have a wider viewing angle?

A: The MPR5BWD features a diffused lens, which distributes light across a 40° viewing angle compared to the MPR5BWC's clear lens and 25° angle. This is a design characteristic that may affect application visibility requirements.

Q: What compliance certifications apply to the substitute part?

A: The MPR5BWD is ROHS3 compliant and REACH Unaffected. These certifications ensure compliance with current environmental and materials regulations.

Q: Can the MPR5BWD be used as a direct replacement in existing designs?

A: Substitution requires validation of optical performance (brightness and viewing angle) against application requirements. Electrical and mechanical compatibility are confirmed; however, the differences in millicandela rating and lens transparency must be evaluated for specific use cases.
