PM3-KHD LED Panel Indicator Equivalent & Substitute Parts

Part Overview

The PM3-KHD is a panel-mounted LED indicator manufactured by Bivar Inc., featuring a red diffused lens with 30 millicandela brightness at 625nm peak wavelength. This component is designed for 2V DC operation at 20mA maximum current with a 120° viewing angle and round 4.83mm panel cutout. The PM3-KHD is classified as obsolete, necessitating identification of active substitute components that maintain functional compatibility within system designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PM3-KHD is determined by mechanical and optical compatibility within the PM3 series. The critical parameters governing substitution are:

Mechanical Compatibility:

• Panel cutout shape: Round
• Panel cutout dimensions: 0.19" (4.83mm)
• Lens size: 5.90mm Dia
• Lens style: Round with Flat Top

Optical Compatibility:

• Lamp color: Red
• Lens color: White
• Lens transparency: Diffused
• Viewing angle: 120°

Electrical Compatibility:

• Current rating: 20mA maximum
• Moisture sensitivity level: 1 (Unlimited)

The substitute parts PM3-PHD and PM3-PRD share identical mechanical and optical characteristics with the PM3-KHD. Both substitutes are active products within the PM3 series, feature the same panel mounting interface, lens configuration, and viewing angle. The primary differences are voltage operating range and brightness specifications, which are application-dependent parameters that do not affect physical interchangeability.

Engineering Selection Recommendations

PM3-PHD Selection Criteria: The PM3-PHD is an active substitute for the PM3-KHD when system voltage requirements are 8V to 48V AC/DC. This part maintains identical mechanical mounting, optical output at 30mcd, and peak wavelength at 625nm. The PM3-PHD provides ROHS3 compliance and IP67 ingress protection, offering enhanced environmental sealing compared to the obsolete PM3-KHD. Inventory availability is 1013 pieces.

PM3-PRD Selection Criteria: The PM3-PRD is an active substitute for the PM3-KHD when system voltage requirements are 8V to 48V AC/DC and increased brightness is required. This part maintains identical mechanical mounting and optical diffusion characteristics. The PM3-PRD provides 40mcd brightness at 645nm peak wavelength, representing a 10mcd increase in luminous intensity. The PM3-PRD includes ROHS3 compliance and IP67 ingress protection. Inventory availability is 1083 pieces.

Voltage Consideration: Both substitute parts operate at 8V to 48V, differing from the PM3-KHD 2V specification. System designs must accommodate this voltage difference through appropriate current-limiting circuitry or voltage regulation.

Frequently Asked Questions (FAQ)

Q: Can PM3-PHD or PM3-PRD be used as direct drop-in replacements for PM3-KHD?

A: Both PM3-PHD and PM3-PRD are mechanically and optically compatible with PM3-KHD. Panel cutout dimensions, lens size, lens style, and viewing angle are identical. However, electrical circuit modifications are required due to voltage rating differences (2V for PM3-KHD versus 8V to 48V for substitutes).

Q: What is the difference between PM3-PHD and PM3-PRD?

A: PM3-PHD maintains the same 30mcd brightness and 625nm wavelength as PM3-KHD. PM3-PRD provides increased brightness at 40mcd with a 645nm peak wavelength. Both operate at 8V to 48V and share identical mechanical specifications.

Q: Why does PM3-KHD require substitution?

A: PM3-KHD is classified as obsolete. PM3-PHD and PM3-PRD are active products with confirmed inventory availability and current manufacturing support.

Q: Are there packaging differences between PM3-KHD and the substitute parts?

A: PM3-KHD packaging is not specified in available documentation. PM3-PHD and PM3-PRD are supplied in bag packaging.

Q: Do the substitute parts meet environmental compliance standards?

A: PM3-PHD and PM3-PRD are ROHS3 compliant. Both parts have moisture sensitivity level 1 (unlimited). PM3-KHD compliance status is not specified in available documentation.

Q: What ingress protection rating do the substitute parts provide?

A: PM3-PHD and PM3-PRD both provide IP67 ingress protection. PM3-KHD ingress protection rating is not specified.

Q: Can PM3-PHD and PM3-PRD be used interchangeably in the same application?

A: PM3-PHD and PM3-PRD are mechanically and optically interchangeable. Selection between them depends on brightness requirements. PM3-PHD provides 30mcd at 625nm; PM3-PRD provides 40mcd at 645nm. Both operate at identical voltage range (8V to 48V) and current (20mA).
