MPR3BWC Equivalent and Substitute Parts

Part Overview

The MPR3BWC is a panel-mounted LED indicator from Bivar Inc.'s MPR3 series, designed for 4V operation at 25mA maximum current. This component features a blue LED with a clear, domed lens and a 430nm peak wavelength, rated at 15 millicandelas with a 20° viewing angle. The part is currently classified as obsolete, making it necessary to identify compatible substitute components that maintain equivalent electrical and mechanical parameters for continued system integration.

Key Parameters

Substitute Part Grouping Explanation

The MPR3BWD serves as a direct substitute based on matching critical electrical and mechanical parameters. Substitution eligibility is determined by the following constraints:

Mandatory Compatibility Parameters (Must Match):

• Voltage (Vf): 4V
• Current (If Max): 25mA
• Panel Cutout Shape: Round
• Panel Cutout Dimensions: 0.24" (6.10mm)
• Lens Size: 3mm, T-1
• Wavelength - Peak: 430nm
• Lamp Color: Blue
• Lens Style: Round with Domed Top
• Moisture Sensitivity Level: 1 (Unlimited)
• Series: MPR3

The MPR3BWD meets all mandatory compatibility parameters, allowing it to function as a drop-in replacement within the same panel assembly without modification to cutout dimensions or electrical circuit design.

Parameter Comparison

Engineering Selection Recommendations

The MPR3BWD is the designated substitute for the obsolete MPR3BWC, providing continuity for system designs requiring blue LED panel indicators at 4V and 25mA operation. Both components are classified under the same manufacturer series and maintain identical electrical parameters and mechanical mounting specifications.

The primary differentiators between the original and substitute are:

• Lens Transparency: MPR3BWD features a diffused lens compared to the clear lens of MPR3BWC, resulting in wider light distribution (35° viewing angle versus 20°).
• Millicandela Output: MPR3BWD is rated at 10mcd versus 15mcd for MPR3BWC, reflecting reduced peak brightness associated with the diffused lens design.
• Product Availability: MPR3BWD is active in production with immediate availability, while MPR3BWC is obsolete.

The MPR3BWD is fully compliant with ROHS3 regulations and carries unlimited moisture sensitivity rating (MSL 1), meeting standard industrial component reliability criteria. Both parts carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications.

Frequently Asked Questions (FAQ)

Q: Can the MPR3BWD be directly substituted for the MPR3BWC without circuit modifications?

A: Yes. Both components maintain identical voltage (4V), current (25mA), and mechanical panel cutout specifications (0.24"/6.10mm round), allowing direct installation into existing panel assemblies without modification.

Q: What is the primary difference in optical performance between these components?

A: The MPR3BWC features a clear lens with 15mcd brightness and a 20° viewing angle, while the MPR3BWD features a diffused lens with 10mcd brightness and a 35° viewing angle. The diffused lens provides wider light distribution at reduced peak intensity.

Q: Are there compliance or environmental differences between the two parts?

A: The MPR3BWD is ROHS3 compliant and REACH unaffected. The MPR3BWC specifications do not reference these certifications in the provided data. Both parts carry MSL 1 (unlimited moisture sensitivity) rating.

Q: What packaging format is the MPR3BWD supplied in?

A: The MPR3BWD is supplied in tray packaging. The original MPR3BWC packaging designation is not specified in the available data.

Q: How do the lens color and transparency differences affect application suitability?

A: The MPR3BWC provides a colorless lens that transmits light with minimal tinting, while the MPR3BWD uses a blue-tinted diffused lens. Applications requiring natural color rendering or narrow-angle illumination may require evaluation of the optical characteristics, particularly regarding lens color and viewing angle differences.
