Key Parameters

Substitute Part Grouping Explanation

Substitution of the PM3-KGD is determined by the following critical parameters that must remain constant or compatible:

Electrical Parameters (Must Match):

• Forward Voltage: 2.1V
• Maximum Current: 20mA
• Wavelength - Peak: 568nm (green spectrum)
• Viewing Angle: 120°

Mechanical Parameters (Must Be Compatible):

• Panel Cutout Shape: Round
• Lens Color: Green
• Mounting Style: Panel-mounted

Acceptable Variations:

• Millicandela Rating: May differ within application tolerance
• Lens Transparency: Diffused or non-diffused acceptable if electrical parameters match
• Lens Size: May vary if panel cutout accommodates
• Panel Cutout Dimensions: May vary within mechanical compatibility
• Lens Style: Round configuration acceptable with flat or domed top

The PM3-KNGD qualifies as a substitute based on matching electrical specifications (2.1V, 20mA, 568nm, 120° viewing angle) and compatible mechanical configuration (round panel mount, green LED).

Engineering Selection Recommendations

PM3-KNGD as Primary Substitute:

The PM3-KNGD is the designated substitute for the obsolete PM3-KGD based on the following engineering criteria:

1. Electrical Compatibility: Identical forward voltage (2.1V), maximum current (20mA), wavelength (568nm), and viewing angle (120°) ensure direct functional equivalence in circuit applications.

2. Mechanical Compatibility: Both components feature round panel-mount configurations with compatible lens sizes (5.90mm vs. 5.80mm diameter). Panel cutout dimension variation (0.19" vs. 0.25") requires mechanical panel assessment for accommodation.

3. Product Status Advantage: PM3-KNGD holds Active product status with current manufacturing availability (959 pcs in stock), eliminating obsolescence risk associated with PM3-KGD.

4. Compliance Alignment: Both parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, maintaining regulatory consistency.

5. Brightness Consideration: PM3-KNGD provides 14mcd versus PM3-KGD's 30mcd. Application brightness requirements must be evaluated against this reduction in luminous intensity.

6. RoHS Compliance: PM3-KNGD carries ROHS3 Compliant certification, providing environmental compliance advantage over the obsolete PM3-KGD.

Frequently Asked Questions (FAQ)

Q: Can PM3-KNGD directly replace PM3-KGD in all applications?

A: Electrical and optical parameters (voltage, current, wavelength, viewing angle) are identical, enabling direct functional replacement in circuit design. Mechanical panel cutout dimensions differ (0.19" vs. 0.25"), requiring verification that the panel aperture accommodates the larger cutout requirement of PM3-KNGD.

Q: What is the brightness difference between these parts?

A: PM3-KGD provides 30mcd while PM3-KNGD provides 14mcd. Applications requiring specific brightness levels must evaluate whether the 14mcd output of PM3-KNGD meets functional requirements. Both parts operate at identical electrical parameters (2.1V, 20mA).

Q: Are there packaging differences between PM3-KGD and PM3-KNGD?

A: PM3-KGD packaging is listed as "-" (unspecified), while PM3-KNGD is supplied in Bag packaging. This represents a packaging format change with no impact on component functionality.

Q: What is the lens transparency difference?

A: PM3-KGD features a diffused lens, while PM3-KNGD lens transparency is not specified in available documentation. Both maintain identical green lamp color and 120° viewing angle. Lens style differs (flat top vs. domed top), which may affect light distribution characteristics.

Q: Why is PM3-KNGD recommended over PM3-KGD?

A: PM3-KNGD holds Active product status with current manufacturing availability, eliminating the obsolescence constraint of PM3-KGD. Electrical specifications remain identical, ensuring functional compatibility. ROHS3 compliance provides environmental regulatory advantage.

Q: Are there any compliance or certification concerns with substitution?

A: Both parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. PM3-KNGD carries ROHS3 Compliant certification. Moisture Sensitivity Level is identical (1 - Unlimited) for both components.
