PM5-KHD LED Panel Indicator Equivalent & Substitute Parts

Part Overview

The PM5-KHD is a panel-mounted LED indicator manufactured by Bivar Inc., designed for applications requiring a red diffused lens with 25 millicandela brightness output at 625nm wavelength. This component operates at 2V with a maximum current of 20mA and features a 120° viewing angle with a 9.91mm round panel cutout.

The PM5-KHD is classified as obsolete. Locating equivalent or substitute components is necessary to support ongoing maintenance, repair, and new design requirements where this part is specified or functionally required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PM5-KHD is determined by alignment across optical, mechanical, and electrical parameters. The following criteria establish functional equivalence:

Optical Parameters (Critical):

• Lamp color: Red
• Wavelength peak: 625nm
• Millicandela rating: 25mcd
• Viewing angle: 120°
• Lens transparency: Diffused
• Lens color: White

Mechanical Parameters (Critical):

• Panel cutout shape: Round
• Panel cutout dimensions: 0.39" (9.91mm)
• Lens size: 9.70mm diameter
• Lens style: Round with flat top

Electrical Parameters (Application-Dependent):

• Current rating: 20mA (consistent across all candidates)
• Voltage rating: Varies by application requirements

Environmental Parameters:

• Moisture sensitivity level: 1 (Unlimited)

The PM5-PHD satisfies all optical and mechanical parameters. The primary difference is voltage rating (8V ~ 48V versus 2V) and the addition of integrated wiring with IP67 ingress protection. Selection between these parts depends on the specific voltage requirements of the target application circuit.

Parameter Comparison

Engineering Selection Recommendations

PM5-PHD Selection Criteria:

The PM5-PHD is the active production equivalent within the PM5 series. It maintains identical optical and mechanical specifications to the PM5-KHD, ensuring direct panel cutout compatibility and visual performance characteristics.

Selection of the PM5-PHD is appropriate when:

1. The application circuit operates within the 8V to 48V AC/DC range
2. Integrated wiring termination is acceptable or preferred over direct solder connections
3. Enhanced ingress protection (IP67) is required or beneficial for the installation environment
4. Active product status and ongoing availability are required for production or long-term support

PM5-KHD Retention Criteria:

The PM5-KHD remains the only option when:

1. The application circuit operates at exactly 2V
2. Direct panel termination without integrated wiring is required
3. Existing inventory of PM5-KHD components is available and acceptable for use

The PM5-KHD is classified as obsolete. New designs should incorporate the PM5-PHD to ensure long-term component availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the PM5-PHD directly replace the PM5-KHD in an existing 2V circuit?

A: No. The PM5-PHD is rated for 8V ~ 48V operation. Applying 2V to the PM5-PHD will result in insufficient forward voltage and non-functional operation. The PM5-KHD must be retained for 2V applications.

Q: Are the optical outputs identical between PM5-KHD and PM5-PHD?

A: Yes. Both components produce identical red light output at 625nm wavelength with 25mcd brightness and 120° viewing angle. The diffused white lens provides identical light distribution characteristics.

Q: Will the PM5-PHD fit the same panel cutout as the PM5-KHD?

A: Yes. Both components require a 0.39" (9.91mm) round panel cutout. The mechanical form factor is identical, allowing direct panel mounting compatibility.

Q: What is the difference between the termination styles?

A: The PM5-KHD uses direct panel termination for solder connection. The PM5-PHD includes integrated wiring for connection to external circuits. The PM5-PHD is supplied in a bag package format.

Q: Does the PM5-PHD provide better environmental protection?

A: Yes. The PM5-PHD carries an IP67 ingress protection rating, providing sealed protection against dust and temporary water immersion. The PM5-KHD does not specify an ingress protection rating.

Q: Are both parts RoHS compliant?

A: The PM5-PHD is explicitly RoHS3 compliant. The PM5-KHD RoHS status is not specified in the provided data. Both parts carry ECCN EAR99 classification and HTSUS code 8541.41.0000.

Q: What is the current consumption for both parts?

A: Both the PM5-KHD and PM5-PHD are rated for a maximum current of 20mA. This specification is identical across both components.

Q: Why is the PM5-KHD classified as obsolete?

A: The PM5-KHD is no longer in active production. The PM5-PHD serves as the current production equivalent within the PM5 series, offering enhanced features including integrated wiring and IP67 protection while maintaining identical optical and mechanical specifications.
