MPR3AC LED Panel Indicator Equivalent & Substitute Parts

Part Overview

The MPR3AC is an amber LED panel indicator manufactured by Bivar Inc., designed for panel-mount applications with wire termination. This component is classified as obsolete, necessitating identification of active substitute parts for ongoing production and maintenance applications. The MPR3AC features a 3mm T-1 lens with a clear, domed top design, operating at 2V with a maximum current of 30mA and a brightness rating of 40mcd at a 605nm wavelength.

Due to its obsolete status, the MPR3AC requires substitution with active product alternatives that maintain electrical and mechanical compatibility within the MPR3 series.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPR3AC is determined by strict adherence to the following critical parameters:

Electrical Compatibility:

• Operating voltage: 2V (forward voltage, typical)
• Maximum current: 30mA
• Peak wavelength: 605nm (amber spectrum)

Mechanical Compatibility:

• Lens size: 3mm, T-1 form factor
• Panel cutout shape: Round
• Panel cutout dimensions: 0.24" (6.10mm)
• Lens style: Round with domed top
• Termination: Wire termination for panel mounting

Environmental & Regulatory Compliance:

• Moisture Sensitivity Level: 1 (Unlimited)
• ECCN classification: EAR99
• HTSUS code: 8541.41.0000

The MPR3AD substitute part maintains all critical electrical and mechanical parameters. Variations in lens transparency (clear versus diffused), lens color (colorless versus amber), millicandela rating (40mcd versus 25mcd), and viewing angle (20° versus 35°) represent optical performance differences that do not prevent functional substitution within the same electrical and mechanical envelope.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: MPR3AD

The MPR3AD is the direct substitute for the obsolete MPR3AC. Both components share identical electrical ratings (2V, 30mA), mechanical form factors (3mm T-1 lens, 0.24" round panel cutout), and regulatory classifications (EAR99, HTSUS 8541.41.0000).

The MPR3AD is classified as an active product with RoHS3 compliance, ensuring continued availability and regulatory alignment for new designs and production continuity. The MPR3AD is supplied in tray packaging with 665 units currently in stock.

Optical Performance Differences:

The MPR3AD exhibits reduced brightness (25mcd versus 40mcd) and an expanded viewing angle (35° versus 20°) compared to the MPR3AC. The lens is amber-tinted with diffused transparency, whereas the MPR3AC features a colorless lens with clear transparency. These optical characteristics result in different light distribution patterns and perceived brightness intensity, which must be evaluated against specific application requirements.

Compliance Status:

The MPR3AD meets RoHS3 compliance requirements, whereas the MPR3AC product status does not specify RoHS compliance. For applications requiring RoHS certification, the MPR3AD is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the MPR3AD directly replace the MPR3AC in existing designs?

A: The MPR3AD maintains identical electrical (2V, 30mA) and mechanical (3mm T-1, 0.24" round cutout) specifications, enabling direct physical and electrical substitution. Optical performance differs due to reduced brightness (25mcd versus 40mcd) and expanded viewing angle (35° versus 20°). Application-specific requirements must determine acceptability of these optical changes.

Q: What are the key differences between MPR3AC and MPR3AD?

A: The primary differences are optical: the MPR3AD has a 15mcd lower brightness rating, a 15° wider viewing angle, an amber-tinted lens with diffused transparency (versus colorless clear lens), and is supplied in tray packaging. Electrical and mechanical parameters are identical.

Q: Why is the MPR3AC obsolete?

A: The MPR3AC is classified as obsolete by the manufacturer. The MPR3AD serves as the active replacement within the MPR3 series, maintaining compatibility across all critical electrical and mechanical parameters.

Q: Is the MPR3AD RoHS compliant?

A: Yes, the MPR3AD is RoHS3 compliant. The MPR3AC product status does not specify RoHS compliance.

Q: What is the viewing angle difference between these parts?

A: The MPR3AC has a 20° viewing angle, while the MPR3AD has a 35° viewing angle. The wider viewing angle of the MPR3AD results in light distribution across a broader angular range.

Q: Does the diffused lens of the MPR3AD affect brightness perception?

A: Yes. The MPR3AD's diffused amber lens distributes light across a wider viewing angle (35° versus 20°) and reduces peak brightness to 25mcd versus 40mcd. The diffused lens scatters light more broadly, resulting in different visual characteristics compared to the clear lens of the MPR3AC.

Q: Are there packaging differences between MPR3AC and MPR3AD?

A: The MPR3AD is supplied in tray packaging. The MPR3AC packaging specification is not provided in available documentation.

Q: What is the current inventory status?

A: The MPR3AC has 698 units in stock (new original). The MPR3AD has 665 units in stock (new original, tray packaging).
