PM5GDLW6 LED Panel Indicator - Equivalent & Substitute Parts

Part Overview

The PM5GDLW6 is a panel-mounted LED indicator manufactured by Bivar Inc., classified as a green diffused lens indicator with wire leads. This component is designed for applications requiring visual status indication with a 6-inch wire lead termination. The part is currently listed as Obsolete, which necessitates identification of equivalent substitute components for ongoing production and maintenance requirements. The substitute part PM5GDLW6.0 provides functional continuity for this application.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PM5GDLW6 is determined by strict alignment of the following electrical and mechanical parameters:

Electrical Parameters (Non-Negotiable):

• Forward voltage (Vf): 2.1V
• Maximum current (If): 7mA
• Lamp color: Green

Mechanical Parameters (Non-Negotiable):

• Panel cutout shape: Round
• Panel cutout dimensions: 0.25" (6.35mm)
• Lens size: 5mm, T-1 3/4
• Termination style: Wire leads with 6" (152.40mm) length

Optical Parameters (Non-Negotiable):

• Lens transparency: Diffused
• Viewing angle: 45°

The substitute part PM5GDLW6.0 meets all critical electrical, mechanical, and optical parameters required for direct substitution. Variations in millicandela rating and peak wavelength do not preclude substitution when all primary parameters align.

Engineering Selection Recommendations

Primary Recommendation: PM5GDLW6.0

The PM5GDLW6.0 is the direct equivalent substitute for the obsolete PM5GDLW6. Selection of this substitute is based on the following engineering criteria:

1. Electrical Compatibility: Identical forward voltage (2.1V) and maximum current (7mA) ensure direct circuit compatibility without modification to series resistor networks or power supply specifications.

2. Mechanical Compatibility: Identical panel cutout dimensions (0.25" / 6.35mm), lens size (5mm T-1 3/4), and wire lead length (6") ensure seamless mechanical integration into existing panel assemblies and PCB layouts.

3. Optical Compatibility: Identical lens transparency (diffused) and viewing angle (45°) maintain the intended light distribution characteristics for the application.

4. Product Status: The substitute part is listed as Active, ensuring ongoing availability and supply chain continuity. The main part PM5GDLW6 is Obsolete and should not be specified for new designs or replenishment orders.

5. Regulatory Compliance: PM5GDLW6.0 carries ROHS3 compliance certification, meeting current environmental and regulatory requirements for electronic components in most jurisdictions.

6. Brightness Consideration: The substitute part features a higher millicandela rating (5mcd vs. 1mcd). This increased brightness is compatible with applications designed for the original part and provides enhanced visibility margin. No circuit modification is required.

7. Wavelength Variation: The peak wavelength differs slightly (568nm vs. 555nm), representing a minor shift within the green spectrum. Both wavelengths are within the standard green LED range and are visually indistinguishable in typical indicator applications.

Frequently Asked Questions (FAQ)

Q: Can PM5GDLW6.0 be used as a direct replacement for PM5GDLW6 without circuit modifications?

A: Yes. The substitute part maintains identical electrical ratings (2.1V, 7mA), mechanical dimensions, and optical characteristics. No changes to series resistors, power supply specifications, or panel cutouts are required.

Q: What is the difference in brightness between the two parts?

A: PM5GDLW6.0 provides 5mcd compared to 1mcd for the original part. This represents a 5x increase in luminous intensity. The substitute will appear noticeably brighter in the same circuit configuration. This enhanced brightness is compatible with existing designs and does not require circuit modification.

Q: Are there any wavelength compatibility concerns?

A: The peak wavelength shifts from 555nm to 568nm, both within the standard green spectrum. This difference is not visually significant in typical indicator applications and does not affect functional compatibility.

Q: Why is PM5GDLW6 listed as Obsolete?

A: The original part has been discontinued by the manufacturer. PM5GDLW6.0 is the active equivalent and should be specified for all new designs and component replenishment.

Q: What is the packaging difference between the two parts?

A: PM5GDLW6 is supplied with unspecified packaging, while PM5GDLW6.0 is supplied in Bag packaging. Both parts are identical in form, fit, and function.

Q: Is PM5GDLW6.0 RoHS compliant?

A: Yes. PM5GDLW6.0 is ROHS3 compliant, meeting current environmental regulations for electronic component manufacturing and use.

Q: Can I use PM5GDLW6.0 in applications originally designed for PM5GDLW6?

A: Yes. All critical electrical, mechanical, and optical parameters are identical. The substitute is fully compatible with existing circuit designs, panel assemblies, and application requirements.
