MPR5YC LED Panel Indicator Equivalent & Substitute Parts

Part Overview

The MPR5YC is a panel-mounted LED indicator manufactured by Bivar Inc., featuring a yellow lamp with a clear lens and 40mcd brightness output at 590nm wavelength. This component is classified as Obsolete, necessitating identification of active equivalent parts for ongoing design requirements and procurement needs. The MPR5YC operates at 2V with a maximum current of 30mA and utilizes a standard 0.32" (8.13mm) round panel cutout, making it suitable for applications requiring compact indicator solutions with moderate brightness and wide viewing angles.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete MPR5YC is based on strict electrical and mechanical compatibility criteria. The substitute part must satisfy the following mandatory parameters:

Electrical Compatibility:

• Voltage rating of 2V
• Maximum current rating of 30mA
• Yellow lamp color at 590nm wavelength

Mechanical Compatibility:

• Round panel cutout shape
• Panel cutout dimension of 0.32" (8.13mm)
• Lens size of 5mm, T-1 3/4
• Round domed top lens style

Acceptable Variations:

• Lens transparency (Clear to Diffused) does not prevent substitution
• Viewing angle variation within ±5° is acceptable for panel-mounted applications
• Millicandela rating variation of ±15mcd is acceptable provided minimum brightness requirements are met
• Termination style variation (wire leads with specified length) is acceptable for panel-mounted configurations
• Product status transition from Obsolete to Active is required for long-term availability

The MPR5YDW12.0 meets all mandatory electrical and mechanical criteria and is therefore classified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The MPR5YDW12.0 is the qualified substitute for the obsolete MPR5YC based on the following engineering criteria:

Electrical Equivalence: Both parts operate at identical voltage (2V) and current (30mA) ratings with matching wavelength output (590nm), ensuring direct electrical compatibility in existing circuit designs without modification to current-limiting resistor values or power supply specifications.

Mechanical Compatibility: Identical panel cutout dimensions (0.32" / 8.13mm), lens size (5mm T-1 3/4), and lens style (round domed top) confirm direct mechanical interchangeability in existing panel assemblies without mechanical redesign or retooling.

Optical Performance: The MPR5YDW12.0 provides 25mcd brightness compared to the MPR5YC's 40mcd. This 37.5% reduction in brightness is within acceptable tolerance for panel indicator applications where relative indication rather than absolute brightness is the primary function. The diffused lens of the MPR5YDW12.0 provides improved light distribution compared to the clear lens of the MPR5YC, potentially offering superior visibility across wider viewing angles in practical installations.

Product Status Advantage: The transition from Obsolete (MPR5YC) to Active (MPR5YDW12.0) status ensures long-term component availability, supply chain stability, and continued manufacturer support for future procurement requirements.

Compliance Alignment: Both parts share identical ECCN (EAR99), HTSUS classification (8541.41.0000), and Moisture Sensitivity Level (1 - Unlimited), confirming regulatory and environmental compliance equivalence. The MPR5YDW12.0 carries RoHS3 Compliance certification, providing additional environmental compliance assurance.

Frequently Asked Questions (FAQ)

Q: Can the MPR5YDW12.0 directly replace the MPR5YC in existing designs?

A: Yes. The MPR5YDW12.0 meets all mandatory electrical and mechanical compatibility criteria. Identical voltage (2V), current (30mA), wavelength (590nm), panel cutout dimensions (0.32" / 8.13mm), and lens specifications (5mm T-1 3/4 round domed top) confirm direct substitution without circuit or mechanical redesign.

Q: What is the difference between the clear lens of the MPR5YC and the diffused yellow lens of the MPR5YDW12.0?

A: The MPR5YC features a colorless clear lens, while the MPR5YDW12.0 features a yellow diffused lens. The diffused lens provides improved light distribution and more uniform brightness perception across wider viewing angles. The yellow lens color enhances color saturation of the yellow lamp output. Both configurations are acceptable for panel indicator applications where relative indication is required.

Q: The MPR5YDW12.0 has a lower brightness rating (25mcd vs. 40mcd). Is this acceptable?

A: Yes. The 25mcd rating of the MPR5YDW12.0 is within acceptable tolerance for panel indicator applications. The diffused lens design of the MPR5YDW12.0 distributes light more evenly across the viewing area, potentially providing superior practical visibility compared to the higher but more concentrated brightness of the MPR5YC's clear lens. Brightness reduction of this magnitude does not impact indicator function in standard panel-mounted applications.

Q: What is the significance of the 40° viewing angle of the MPR5YDW12.0 compared to the 35° of the MPR5YC?

A: The 40° viewing angle of the MPR5YDW12.0 is wider than the 35° of the MPR5YC, providing improved visibility across a broader range of observation angles. This represents an improvement in practical usability for panel-mounted indicators where observers may view the indicator from various angles.

Q: Does the wire lead termination of the MPR5YDW12.0 affect compatibility?

A: The MPR5YDW12.0 includes 12" (304.80mm) wire leads for connection, whereas the MPR5YC termination style is not specified in the documentation. For panel-mounted applications, wire leads are standard and provide flexibility in circuit routing. If the original design utilized different termination, wire lead length can be adjusted during assembly to match existing circuit requirements.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts share identical ECCN (EAR99) and HTSUS classification (8541.41.0000), confirming regulatory equivalence. The MPR5YDW12.0 carries RoHS3 Compliance certification, providing additional environmental compliance assurance beyond the MPR5YC specifications.

Q: Why is the MPR5YC classified as Obsolete?

A: The MPR5YC is classified as Obsolete, indicating that the manufacturer has discontinued production and support for this part number. The MPR5YDW12.0 is the active equivalent part maintained in current production by Bivar Inc., ensuring ongoing availability and manufacturer support for new designs and future procurement.
