PM3-KAD LED Panel Indicator Equivalent & Substitute Parts

Part Overview

The PM3-KAD is an amber LED panel indicator manufactured by Bivar Inc., designed for panel-mount applications with a 2V operating voltage and 20mA maximum current rating. This component features a diffused lens with 100mcd brightness output at a 610nm wavelength peak, suitable for visual indication applications requiring moderate luminous intensity.

The PM3-KAD is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PM3-KAD is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Lamp Color: Amber
• Voltage (Vf Typ): 2V
• Current (If Max): 20mA
• Wavelength - Peak: 610nm
• Viewing Angle: 120°
• Panel Cutout Shape: Round

Allowable Variation Parameters:

• Panel Cutout Dimensions: Variation permitted within mechanical tolerance constraints
• Lens Size: Variation permitted within optical performance constraints
• Lens Style: Variation permitted (flat top, domed top, or equivalent geometries)
• Millicandela Rating: Variation permitted within application brightness requirements
• Lens Transparency: Variation permitted (diffused or clear)
• Product Status: Active or obsolete status does not restrict substitution eligibility

The PM3-KNAD meets all mandatory matching parameters and is therefore classified as a direct substitute for the PM3-KAD.

Parameter Comparison

Engineering Selection Recommendations

PM3-KNAD as Substitute for PM3-KAD:

The PM3-KNAD is electrically and optically compatible with the PM3-KAD based on matching voltage, current, wavelength, and viewing angle specifications. Both components share identical electrical ratings (2V, 20mA) and optical characteristics (610nm peak wavelength, 120° viewing angle), ensuring functional equivalence in circuit operation.

The PM3-KNAD holds Active product status with ROHS3 compliance certification, providing superior supply chain availability compared to the obsolete PM3-KAD. Both components carry identical moisture sensitivity level (MSL 1 - Unlimited) and export classification (EAR99), ensuring equivalent handling and regulatory requirements.

Mechanical Considerations:

The panel cutout dimension difference (0.19" vs. 0.25") requires mechanical assessment for panel compatibility. The lens diameter variation (5.90mm vs. 5.80mm) is negligible. The lens style transition from flat top to domed top does not affect electrical or optical performance within the specified 120° viewing angle.

Optical Performance Consideration:

The PM3-KNAD delivers 45mcd brightness output compared to the PM3-KAD's 100mcd rating. This represents a reduction in luminous intensity. Application-specific brightness requirements must be evaluated to determine if this reduction is acceptable for the intended indication function.

Frequently Asked Questions (FAQ)

Q: Can the PM3-KNAD directly replace the PM3-KAD in existing designs?

A: Electrical and optical compatibility is confirmed based on matching voltage (2V), current (20mA), wavelength (610nm), and viewing angle (120°) specifications. Mechanical panel cutout dimensions differ and require assessment for physical fit. Brightness output reduction (45mcd vs. 100mcd) must be evaluated against application requirements.

Q: What is the significance of the panel cutout dimension difference?

A: The PM3-KAD requires a 0.19" (4.83mm) round cutout, while the PM3-KNAD requires a 0.25" (6.35mm) round cutout. Physical panel modification may be necessary if the existing panel is designed for the smaller cutout. Verify panel specifications before component selection.

Q: Does the lens style change from flat top to domed top affect performance?

A: Both lens styles maintain the specified 120° viewing angle and are optically equivalent for indication applications. The domed top geometry does not alter electrical operation or wavelength characteristics.

Q: Why is the PM3-KNAD brightness lower than the PM3-KAD?

A: The PM3-KNAD is rated at 45mcd while the PM3-KAD is rated at 100mcd. This difference reflects the optical design of each component. Application brightness requirements must be confirmed to ensure the lower output is acceptable for the intended visual indication function.

Q: Are there compliance or handling differences between these components?

A: Both components share identical moisture sensitivity level (MSL 1 - Unlimited), export classification (EAR99), and tariff codes (8541.41.0000). No differences in handling, storage, or regulatory requirements exist.

Q: What is the advantage of selecting the PM3-KNAD?

A: The PM3-KNAD holds Active product status with ROHS3 compliance, ensuring current availability and regulatory alignment. The PM3-KAD is classified as obsolete, making long-term supply uncertain.
