LED Panel Indicator MPR5SURC Equivalent & Substitute Parts

Part Overview

The MPR5SURC is a red LED panel indicator manufactured by Bivar Inc., designed for applications requiring a compact, panel-mounted visual indicator. This component features a clear lens with a 500mcd brightness rating, operating at 1.8V and 20mA maximum current. The part is classified as obsolete, making identification of suitable substitute components essential for ongoing production support, maintenance, and design continuity. The MPR5SURC's round 5mm T-1 3/4 form factor and 0.32" (8.13mm) panel cutout dimension establish the mechanical compatibility baseline for equivalent parts.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MPR5SURC is determined by strict alignment across mechanical, electrical, and optical parameters. The following criteria establish the substitution baseline:

Mechanical Compatibility Requirements:

• Panel cutout shape must be round
• Panel cutout dimensions must be 0.32" (8.13mm)
• Lens size must be 5mm, T-1 3/4
• Lens style must be round with domed top

Electrical Compatibility Requirements:

• Maximum current rating must be 20mA
• Forward voltage must support operation within the design circuit (1.8V baseline)

Optical Compatibility Requirements:

• Lamp color must be red
• Viewing angle must be 35°
• Brightness rating (millicandela) must be suitable for the application context

Regulatory Alignment:

• ECCN and HTSUS classifications must match for supply chain continuity

The MPR5RD is identified as a substitute part within the same MPR5 series from Bivar Inc. While this part shares the same mechanical form factor and electrical current rating, variations in forward voltage (2.1V vs. 1.8V), lens transparency (diffused vs. clear), brightness rating (2mcd vs. 500mcd), and wavelength (700nm vs. 640nm) indicate application-specific differences that must be evaluated against circuit design requirements.

Parameter Comparison

Engineering Selection Recommendations

MPR5RD Substitution Criteria:

The MPR5RD is an active production component within the Bivar Inc. MPR5 series and shares identical mechanical form factor and current rating specifications with the obsolete MPR5SURC. Direct mechanical interchangeability is confirmed through matching panel cutout dimensions (0.32" / 8.13mm), lens size (5mm T-1 3/4), and lens style (round with domed top).

Electrical substitution requires circuit-level evaluation due to the 0.3V forward voltage difference (1.8V vs. 2.1V). Applications operating at the minimum voltage threshold of the original design may require resistor or current-limiting adjustment to accommodate the higher forward voltage of the MPR5RD.

Optical performance differs substantially: the MPR5RD operates at 2mcd brightness compared to the MPR5SURC's 500mcd rating, and features a diffused red lens versus the original's clear colorless lens. The wavelength shift from 640nm to 700nm represents a shift toward the far-red spectrum. These optical differences affect visibility, color perception, and application suitability. Applications requiring high brightness or specific wavelength characteristics may not be compatible with the MPR5RD.

Both parts maintain identical Moisture Sensitivity Level (MSL 1 - Unlimited), ECCN (EAR99), and HTSUS (8541.41.0000) classifications, ensuring regulatory and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the MPR5RD be used as a direct replacement for the MPR5SURC in all applications?

A: No. While mechanical interchangeability is confirmed, electrical and optical differences require application-specific evaluation. The 0.3V forward voltage increase and 498mcd brightness reduction are significant parameters that must be validated against circuit design and visibility requirements.

Q: What is the impact of the 0.3V forward voltage difference between these parts?

A: The MPR5RD operates at 2.1V compared to the MPR5SURC's 1.8V. In circuits designed for the lower voltage, this difference may reduce current flow or require adjustment of series resistor values. Circuit simulation or bench testing is necessary to confirm compatibility with existing power supply and current-limiting designs.

Q: How do the optical differences affect substitution?

A: The MPR5SURC provides 500mcd brightness with a clear lens and 640nm wavelength. The MPR5RD provides 2mcd brightness with a diffused red lens and 700nm wavelength. These differences result in significantly lower brightness and altered color perception. Applications requiring high visibility or specific color matching may not be suitable for the MPR5RD.

Q: Are both parts mechanically compatible with the same panel cutout?

A: Yes. Both parts feature identical round panel cutout dimensions of 0.32" (8.13mm), 5mm T-1 3/4 lens size, and round domed top lens style. No mechanical modification to the panel or mounting structure is required.

Q: What is the current rating for both parts?

A: Both the MPR5SURC and MPR5RD are rated for a maximum current of 20mA. Current-limiting circuit design remains consistent between the two parts.

Q: Why is the MPR5SURC obsolete while the MPR5RD is active?

A: The MPR5SURC is classified as obsolete, indicating it is no longer in active production. The MPR5RD remains in active production status, making it available for new designs and ongoing supply. Existing inventory of the MPR5SURC may be available through authorized distributors, but long-term availability cannot be guaranteed.

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

A: No. Both parts share identical ECCN (EAR99), HTSUS (8541.41.0000), and Moisture Sensitivity Level (MSL 1 - Unlimited) classifications. Regulatory and environmental compliance requirements are equivalent.

Q: What packaging format is the MPR5RD supplied in?

A: The MPR5RD is supplied in Tray packaging. Packaging format may affect handling, storage, and integration into assembly processes compared to the original MPR5SURC specification.
