PM5-KRD LED Panel Indicator - Equivalent & Substitute Parts

Part Overview

The PM5-KRD is a panel-mount LED indicator manufactured by Bivar Inc., featuring a red diffused lens with 40mcd brightness at 645nm wavelength. This component is classified as Obsolete, necessitating identification of compatible substitute parts for continued application support. The PM5-KRD operates at 1.7V with a maximum current rating of 20mA and accommodates a 0.39" (9.91mm) round panel cutout.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PM5-KRD with alternative components is determined by strict adherence to the following critical electrical and mechanical parameters:

Electrical Compatibility:

• Forward voltage (Vf): 1.7V
• Maximum current (If): 20mA
• Wavelength - Peak: 645nm (red spectrum)

Mechanical Compatibility:

• Panel cutout shape: Round
• Viewing angle: 120°
• Lens diameter dimensions compatible with 0.39" panel cutout

The PM5-KNRD qualifies as a substitute based on matching electrical specifications (1.7V, 20mA, 645nm wavelength) and identical viewing angle (120°). Variations in lens size (9.10mm vs. 9.70mm), millicandela rating (14mcd vs. 40mcd), lens style (domed top vs. flat top), and panel cutout dimensions represent secondary mechanical differences that do not prevent functional substitution in applications where the primary electrical parameters are sufficient.

Engineering Selection Recommendations

The PM5-KNRD is the identified substitute for the obsolete PM5-KRD based on matching core electrical parameters. The PM5-KNRD holds Active product status and maintains ROHS3 Compliant certification, ensuring continued availability and regulatory compliance for new designs and production applications.

Both components share identical moisture sensitivity levels (MSL 1 - Unlimited) and export classifications (ECCN EAR99, HTSUS 8541.41.0000), confirming equivalent regulatory and environmental handling requirements.

The brightness difference (14mcd PM5-KNRD vs. 40mcd PM5-KRD) represents the primary performance variance and must be evaluated against application illumination requirements. The panel cutout dimension increase (0.41" vs. 0.39") requires verification of available panel space.

Frequently Asked Questions (FAQ)

Q: Can PM5-KNRD directly replace PM5-KRD in existing assemblies?

A: Electrical substitution is valid based on identical voltage (1.7V), current (20mA), wavelength (645nm), and viewing angle (120°) specifications. Physical installation requires confirmation that the 0.41" (10.41mm) panel cutout dimension accommodates the existing 0.39" panel opening, and that the reduced brightness (14mcd vs. 40mcd) satisfies application visibility requirements.

Q: What are the key differences between these parts?

A: The PM5-KNRD features a domed lens top (vs. flat top), smaller lens diameter (9.10mm vs. 9.70mm), lower brightness output (14mcd vs. 40mcd), and a marginally larger panel cutout dimension (0.41" vs. 0.39"). Electrical specifications and wavelength remain identical.

Q: Are there compliance considerations when substituting PM5-KRD?

A: The PM5-KNRD maintains identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications as the original PM5-KRD. The PM5-KNRD carries ROHS3 compliance certification, ensuring regulatory alignment for current manufacturing standards.

Q: What inventory status should influence component selection?

A: PM5-KNRD is available in Active status with 1022 pcs in stock, while PM5-KRD is Obsolete with 737 pcs remaining. New designs must utilize PM5-KNRD to ensure long-term supply continuity.
