Equivalent & Substitute Parts for PM5-KAD

Part Overview

The PM5-KAD is a panel-mounted LED indicator manufactured by Bivar Inc., featuring an amber diffused lens with a 120° viewing angle. This component is rated at 2V, 20mA, and delivers 25mcd at a peak wavelength of 605nm. The part is classified as obsolete, necessitating identification of active equivalent components for continued system design and maintenance applications. Substitute parts must maintain electrical compatibility while accommodating mechanical and optical parameter variations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PM5-KAD is determined by strict alignment of critical electrical and optical parameters. The following criteria establish valid equivalency:

Critical Parameters (Must Match):

• Voltage: 2V
• Current: 20mA
• Lamp Color: Amber
• Wavelength - Peak: 605nm
• Viewing Angle: 120°
• Panel Cutout Shape: Round

Reference Parameters (Allowable Variation):

• Millicandela Rating: Variation acceptable within system design tolerance
• Lens Size: Mechanical accommodation required
• Panel Cutout Dimensions: Mechanical accommodation required
• Lens Transparency and Style: Optical performance variation acceptable

The PM5-KNAD meets all critical electrical and optical parameters, establishing it as a valid substitute despite differences in millicandela rating (9mcd vs. 25mcd), lens size (9.10mm vs. 9.70mm), and panel cutout dimensions (0.41" vs. 0.39").

Parameter Comparison

Engineering Selection Recommendations

The PM5-KNAD is the designated substitute for the obsolete PM5-KAD based on the following engineering criteria:

Electrical Compatibility: Both components operate at identical voltage (2V) and current (20mA) specifications, ensuring direct circuit compatibility without modification to power supply or current-limiting circuitry.

Optical Compatibility: Both components emit amber light at 605nm peak wavelength with 120° viewing angle, maintaining color consistency and visibility characteristics in indicator applications.

Mechanical Accommodation: The PM5-KNAD requires panel cutout modification from 0.39" to 0.41" diameter and accommodates a 9.10mm lens versus the original 9.70mm. These mechanical variations are within standard panel fabrication tolerances and do not affect electrical function.

Product Status Advantage: The PM5-KNAD is active in production, ensuring long-term availability and supply chain continuity compared to the obsolete PM5-KAD.

Compliance Advantage: The PM5-KNAD carries ROHS3 compliance certification, meeting current environmental and regulatory requirements. Both components share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications.

Brightness Consideration: The PM5-KNAD delivers 9mcd versus the original 25mcd. System designers must evaluate whether reduced brightness is acceptable for the intended application. If brightness preservation is critical, alternative substitutes with higher millicandela ratings should be evaluated.

Frequently Asked Questions (FAQ)

Q: Can PM5-KNAD directly replace PM5-KAD without circuit modification?

A: Yes. Both components share identical electrical specifications (2V, 20mA), eliminating the need for circuit redesign. No modifications to power supply, resistors, or current-limiting components are required.

Q: What mechanical changes are required when substituting PM5-KNAD for PM5-KAD?

A: The panel cutout diameter must be enlarged from 0.39" (9.91mm) to 0.41" (10.41mm). The lens diameter decreases from 9.70mm to 9.10mm. These are mechanical accommodations only and do not affect electrical performance.

Q: Will the PM5-KNAD provide equivalent brightness?

A: No. The PM5-KNAD delivers 9mcd compared to the original 25mcd. This represents a reduction in light output. System designers must confirm that reduced brightness is acceptable for the application. If brightness preservation is required, alternative components with higher millicandela ratings must be evaluated.

Q: Are there differences in lens appearance between PM5-KAD and PM5-KNAD?

A: Yes. The PM5-KAD features a round lens with flat top, while the PM5-KNAD features a round lens with domed top. Both maintain the same 120° viewing angle and amber color. The domed top may affect light distribution characteristics slightly.

Q: Is PM5-KNAD compliant with current environmental regulations?

A: Yes. The PM5-KNAD is ROHS3 compliant, meeting current environmental and regulatory requirements. The original PM5-KAD has vendor-undefined RoHS status.

Q: What is the availability status of PM5-KNAD?

A: The PM5-KNAD is active in production with 931 pieces in current inventory. The PM5-KAD is obsolete with limited remaining stock (735 pieces).

Q: Do both components share the same export classification?

A: Yes. Both PM5-KAD and PM5-KNAD carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, simplifying procurement and compliance documentation.

Q: What is the moisture sensitivity level for PM5-KNAD?

A: Both components carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or assembly.
