MPR3RC LED Panel Indicator Equivalent & Substitute Parts

Part Overview

The MPR3RC is a red LED panel indicator manufactured by Bivar Inc., designed for panel-mount applications with wire termination. This component features a clear lens with a 700nm peak wavelength and 2.5mcd brightness rating. The MPR3RC is classified as obsolete, making identification of suitable substitute components essential for ongoing production and maintenance applications. Substitute parts must maintain electrical compatibility (2.1V forward voltage, 20mA maximum current) and mechanical fit (0.24" round panel cutout, 3mm T-1 lens form factor) while accommodating differences in lens transparency and brightness characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete MPR3RC is based on strict electrical and mechanical compatibility criteria. All substitute candidates must satisfy the following mandatory parameters:

Electrical Compatibility Requirements:

• Forward voltage (Vf): 2.1V (identical)
• Maximum current (If): 20mA (identical)
• Lamp color: Red (identical)
• Peak wavelength: 700nm (identical)

Mechanical Compatibility Requirements:

• Panel cutout shape: Round (identical)
• Panel cutout dimensions: 0.24" / 6.10mm (identical)
• Lens size: 3mm, T-1 form factor (identical)
• Lens style: Round with domed top (identical)

Allowable Variations: Substitute parts may differ in the following parameters without affecting functional compatibility in panel-mount applications:

• Lens transparency (clear vs. diffused)
• Lens color (colorless vs. red-tinted)
• Millicandela rating (brightness level)
• Viewing angle (within optical performance envelope)
• Packaging format (bulk vs. tray)
• Product status (active vs. obsolete)

The MPR3RD meets all mandatory electrical and mechanical criteria and is therefore qualified as a direct substitute for the MPR3RC.

Parameter Comparison

Engineering Selection Recommendations

The MPR3RD is a qualified substitute for the obsolete MPR3RC based on the following engineering criteria:

Electrical Compatibility: Both components operate at identical forward voltage (2.1V) and maximum current (20mA), ensuring direct circuit compatibility without modification to existing drive electronics or current-limiting resistor calculations.

Mechanical Compatibility: Both components feature identical panel cutout dimensions (0.24" / 6.10mm round), lens form factor (3mm T-1), and mounting style (round domed top), enabling direct mechanical substitution in existing panel assemblies without tooling or fixture changes.

Regulatory and Compliance Status: The MPR3RD is classified as active product status with ROHS3 compliance and REACH unaffected designation, providing assurance of ongoing availability and regulatory alignment. The MPR3RC, being obsolete, presents supply chain risk and potential compliance documentation gaps.

Optical Performance Considerations: The MPR3RD exhibits lower brightness (2.0mcd vs. 2.5mcd) and narrower viewing angle (20° vs. 35°) due to diffused lens construction compared to the clear lens of the MPR3RC. These optical differences are allowable variations that do not affect electrical circuit operation but may impact visual indication characteristics in specific application contexts.

Packaging: The MPR3RD is supplied in tray packaging, which may differ from original MPR3RC packaging format but does not affect component functionality or circuit performance.

Frequently Asked Questions (FAQ)

Q: Can the MPR3RD be used as a direct replacement for the MPR3RC in existing designs?

A: Yes. The MPR3RD meets all mandatory electrical and mechanical compatibility criteria. Both components operate at 2.1V forward voltage and 20mA maximum current, and both fit the 0.24" round panel cutout with identical 3mm T-1 lens form factor. No circuit modifications are required.

Q: What are the differences between the MPR3RC and MPR3RD?

A: The primary differences are lens transparency and brightness. The MPR3RC features a clear lens with 2.5mcd brightness and 35° viewing angle. The MPR3RD features a diffused red lens with 2.0mcd brightness and 20° viewing angle. These differences do not affect electrical operation but may alter visual appearance and light distribution characteristics.

Q: Does the diffused lens of the MPR3RD affect circuit operation?

A: No. Lens transparency and color are optical characteristics that do not impact electrical performance. The forward voltage, current requirements, and circuit compatibility remain identical between the two components.

Q: Is the MPR3RD available in the same packaging as the MPR3RC?

A: The MPR3RD is supplied in tray packaging. Original MPR3RC packaging format is not specified in the provided data. Packaging format does not affect component functionality but may require adjustment to receiving and handling procedures.

Q: Why is the MPR3RC classified as obsolete?

A: Product status is determined by manufacturer lifecycle decisions. The MPR3RC is no longer in active production. The MPR3RD, as an active product from the same manufacturer and series, provides continuity of supply for equivalent functionality.

Q: Are there any compliance or regulatory differences between the two components?

A: Both components share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. The MPR3RD carries ROHS3 compliance and REACH unaffected designation, confirming regulatory alignment with current standards.

Q: What is the moisture sensitivity level for both components?

A: Both the MPR3RC and MPR3RD are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or soldering processes.
