PM3RC LED Panel Indicator Equivalent & Substitute Parts

Part Overview

The PM3RC 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 2.5mcd brightness at 700nm wavelength and operates at 2.1V with 20mA maximum current. The PM3RC is classified as obsolete, making identification of suitable substitute components essential for ongoing production and maintenance applications. Equivalent parts must maintain compatibility with the electrical ratings, mechanical form factor, and optical characteristics specified for this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the PM3RC must satisfy the following criteria based on allowed electrical and mechanical parameters:

Electrical Compatibility Requirements:

• Forward voltage (Vf): 2.1V
• Maximum current (If): 20mA
• Wavelength peak: 700nm

Mechanical Compatibility Requirements:

• Lens size: 3mm, T-1
• Panel cutout shape: Round
• Panel cutout dimensions: 0.16" (4.06mm)
• Lens style: Round with domed top
• Wire termination configuration

Environmental Compatibility:

• Moisture Sensitivity Level: 1 (Unlimited)

The PM3RD qualifies as a substitute based on matching all electrical parameters (2.1V, 20mA, 700nm), identical mechanical form factor (3mm T-1 lens, round domed top, 0.16" round cutout), and equivalent environmental rating. Variations in lens transparency (clear versus diffused) and millicandela rating (2.5mcd versus 2mcd) represent acceptable optical differences within the product category, as both components maintain the same electrical and mechanical interface specifications.

Engineering Selection Recommendations

Primary Substitute: PM3RD

The PM3RD is the designated substitute for the obsolete PM3RC based on the following engineering criteria:

Electrical Equivalence: Both components operate at identical forward voltage (2.1V) and maximum current (20mA) specifications, ensuring direct compatibility with existing circuit designs and power supply configurations.

Mechanical Compatibility: The PM3RD maintains the same mechanical interface as the PM3RC, including 3mm T-1 lens form factor, round domed top profile, and 0.16" (4.06mm) round panel cutout dimensions. Wire termination configuration is preserved, allowing direct substitution in panel-mount applications without mechanical redesign.

Optical Characteristics: While the PM3RD features a diffused lens compared to the clear lens of the PM3RC, both components emit at the identical 700nm wavelength. The millicandela rating difference (2mcd versus 2.5mcd) and expanded viewing angle (40° versus 30°) represent acceptable optical variations within the red LED indicator product category.

Product Status Advantage: The PM3RD holds active product status with current manufacturing availability, eliminating supply chain risk associated with the obsolete PM3RC. The component is RoHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Compliance Alignment: Both components share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, maintaining regulatory consistency for procurement and export documentation.

Frequently Asked Questions (FAQ)

Q: Can the PM3RD directly replace the PM3RC in existing designs?

A: Yes. The PM3RD provides direct electrical and mechanical substitution. Both components operate at 2.1V and 20mA, feature identical 3mm T-1 lens form factors, and mount through 0.16" (4.06mm) round panel cutouts. Wire termination configuration is preserved.

Q: What is the difference between the clear lens of the PM3RC and the diffused lens of the PM3RD?

A: The PM3RC features a clear lens providing focused light output at a 30° viewing angle with 2.5mcd brightness. The PM3RD features a diffused lens providing dispersed light output at a 40° viewing angle with 2mcd brightness. Both emit at 700nm wavelength. Lens transparency selection depends on application requirements for light distribution and visibility angle.

Q: Are there electrical performance differences between these components?

A: No. Both the PM3RC and PM3RD operate at identical electrical specifications: 2.1V forward voltage and 20mA maximum current. Circuit design and power supply configurations require no modification.

Q: Why is the PM3RC classified as obsolete?

A: The PM3RC is no longer in active production. The PM3RD represents the current active equivalent within the PM3 series, offering the same electrical and mechanical interface with improved product availability and regulatory compliance.

Q: What packaging is available for the PM3RD?

A: The PM3RD is supplied in tray packaging. Current inventory availability is 1980 pieces in new original condition.

Q: Are there compliance or certification differences?

A: Both components share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. The PM3RD includes RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements. Both components have Moisture Sensitivity Level 1 (Unlimited).

Q: What viewing angle should I select for my application?

A: The PM3RC provides 30° viewing angle with higher brightness concentration (2.5mcd). The PM3RD provides 40° viewing angle with broader light distribution (2mcd). Select based on required visibility angle and brightness requirements for your specific panel-mount application.
