Equivalent & Substitute Parts for PM3GDW6

Part Overview

The PM3GDW6 is a panel mount LED indicator assembly manufactured by Bivar Inc., featuring a 3mm green diffused lens with wire leads. This component is classified as obsolete, necessitating identification of active substitute parts for ongoing applications requiring equivalent or compatible green LED panel indicators with similar mechanical and electrical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PM3GDW6 is determined by the following critical parameters:

Mechanical Compatibility:

• Panel cutout shape and dimensions (Round, 0.16" / 4.06mm)
• Lens size (3mm, T-1)
• Lens style (Round with Domed Top)
• Termination style (Wire Leads)

Electrical Compatibility:

• Lamp color (Green)
• Voltage range (Typ 2.1V to 2.2V)
• Current rating (20mA to 40mA maximum)
• Wavelength - Peak (565nm to 568nm)

Environmental & Regulatory:

• Moisture Sensitivity Level (MSL 1)
• ECCN classification (EAR99)
• HTSUS code (8541.41.0000)

Substitute parts must maintain compatibility across all three categories. Variations in lens transparency (diffused vs. clear), viewing angle, and millicandela rating are permissible within the electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

PM3GDW6.0 (Bivar Inc.): This part is the direct successor to the obsolete PM3GDW6, maintaining identical mechanical compatibility and diffused lens transparency. The part is active and ROHS3 compliant. Electrical parameters are within acceptable tolerance: voltage reduced from 2.2V to 2.1V (4.5% variance) and current reduced from 30mA to 20mA (33% reduction). The millicandela rating decreases from 30mcd to 25mcd. This substitute is suitable for applications where the lower current draw and reduced brightness are acceptable within circuit design parameters.

5580501007F (Dialight): This part maintains mechanical compatibility with identical panel cutout dimensions and 3mm T-1 lens size. The part is active and ROHS3 compliant. Electrical parameters are compatible: voltage at 2.1V and current at 40mA (higher than original). The lens transparency differs (clear vs. diffused), resulting in higher millicandela output (70mcd vs. 30mcd). Wire lead length extends to 14" versus the original 6". This substitute is suitable for applications requiring higher brightness output and longer lead routing, provided the clear lens transparency is acceptable.

Frequently Asked Questions (FAQ)

Q: Can PM3GDW6.0 be used as a direct replacement for PM3GDW6?

A: PM3GDW6.0 provides mechanical compatibility and maintains the diffused lens characteristic. Electrical differences exist: lower voltage (2.1V vs. 2.2V) and reduced maximum current (20mA vs. 30mA). Circuit design must accommodate these parameters. The part is active and ROHS3 compliant, making it suitable for new designs and obsolescence mitigation.

Q: What are the key differences between PM3GDW6.0 and 5580501007F?

A: Both parts share mechanical compatibility and active product status. PM3GDW6.0 maintains diffused lens transparency identical to the original PM3GDW6, while 5580501007F features a clear lens. Current ratings differ: PM3GDW6.0 at 20mA maximum versus 5580501007F at 40mA maximum. Wire lead length differs: PM3GDW6.0 provides 6" leads matching the original, while 5580501007F provides 14" leads. Brightness output differs: PM3GDW6.0 at 25mcd versus 5580501007F at 70mcd.

Q: Are there viewing angle differences between substitute parts?

A: The original PM3GDW6 specifies a 45° viewing angle. PM3GDW6.0 specifies 40°, representing a 5° reduction. The 5580501007F does not specify viewing angle in the provided data. Applications requiring specific viewing angle performance must evaluate this parameter against circuit requirements.

Q: Do substitute parts maintain the same panel cutout compatibility?

A: Yes. Both PM3GDW6.0 and 5580501007F maintain the round panel cutout dimension of 0.16" (4.06mm), identical to the original PM3GDW6. Mechanical panel integration remains unchanged.

Q: What is the impact of lens transparency differences?

A: The original PM3GDW6 and substitute PM3GDW6.0 feature diffused lenses, providing uniform light distribution. The 5580501007F features a clear lens, concentrating light output and resulting in higher millicandela rating (70mcd vs. 30mcd). Application requirements determine which lens transparency is appropriate.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both PM3GDW6.0 and 5580501007F are ROHS3 compliant. The original PM3GDW6 does not specify RoHS status in the provided data.

Q: How do current ratings affect circuit design?

A: The original PM3GDW6 specifies 30mA maximum current. PM3GDW6.0 reduces this to 20mA, while 5580501007F increases to 40mA. Current-limiting resistor values in series circuits must be recalculated based on the selected substitute part to maintain proper LED operation and longevity.
