PM3GDLW9 Equivalent & Substitute Parts

Part Overview

The PM3GDLW9 is a panel-mounted LED indicator manufactured by Bivar Inc., featuring a 3mm green diffused lens with 9-inch wire leads. This component is classified as Obsolete, necessitating identification of equivalent substitute parts for ongoing applications. The part operates at 2.1V forward voltage with 7mA maximum current, delivering 2mcd luminous intensity at a 40° viewing angle. Due to its obsolete status, active equivalent parts are required to maintain design continuity and ensure supply chain availability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PM3GDLW9 are identified based on strict alignment with the following critical parameters:

Primary Compatibility Criteria:

• Lamp color: Green
• Lens size: 3mm, T-1
• Panel cutout shape and dimensions: Round, 0.16" (4.06mm)
• Lens style: Round with domed top
• Forward voltage: 2.1V
• Termination style: Wire leads

Identified Substitutes:

Group 1 - Direct Equivalent (Active Status) PM3GDLW9.0 (Bivar Inc.) represents a direct equivalent with identical electrical and mechanical specifications. This part maintains the same voltage, current rating, lens configuration, and panel mounting interface. The primary distinction is active product status and RoHS3 compliance certification.

Group 2 - Functional Equivalent (Different Specifications) 5580501007F (Dialight) shares the same forward voltage (2.1V), lens size (3mm, T-1), panel cutout dimensions (0.16"/4.06mm), and termination style (wire leads). However, this part operates at 40mA maximum current (versus 7mA), delivers 70mcd luminous intensity (versus 2mcd), features clear lens transparency (versus diffused), and includes 14-inch wire leads (versus 9-inch). These differences indicate functional equivalence for applications requiring higher brightness but require circuit redesign for current limiting.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (No Circuit Modification Required): PM3GDLW9.0 is the primary substitute for PM3GDLW9. This part maintains identical electrical ratings (2.1V, 7mA), mechanical configuration (3mm T-1 lens, 0.16" panel cutout, 9-inch wire leads), and optical properties (diffused green lens, 2mcd, 40° viewing angle). The part is currently in active production status with ROHS3 compliance certification, ensuring long-term supply availability and regulatory compliance. No circuit redesign is required.

For Functional Equivalence (Circuit Modification Required): 5580501007F (Dialight) provides functional equivalence when higher luminous intensity is acceptable. This part shares the same forward voltage (2.1V) and panel mounting interface (0.16" round cutout, 3mm T-1 lens). However, the 40mA maximum current rating requires circuit current-limiting adjustment compared to the 7mA specification of PM3GDLW9. The 70mcd brightness output (versus 2mcd) and clear lens transparency (versus diffused) represent significant optical differences. The 14-inch wire leads (versus 9-inch) require mechanical accommodation. This substitute is suitable only when application requirements permit increased brightness and circuit modification is feasible.

Frequently Asked Questions (FAQ)

Q: Can PM3GDLW9.0 be used as a direct drop-in replacement for PM3GDLW9?

A: Yes. PM3GDLW9.0 maintains identical forward voltage (2.1V), maximum current (7mA), lens configuration (3mm T-1 diffused green), panel cutout dimensions (0.16"/4.06mm round), wire lead length (9 inches), and optical output (2mcd, 40° viewing angle). No circuit modification or mechanical redesign is required. The part is currently in active production with ROHS3 compliance.

Q: What are the key differences between PM3GDLW9 and 5580501007F?

A: The primary differences are: (1) Maximum current: 5580501007F operates at 40mA versus 7mA for PM3GDLW9, requiring circuit current-limiting adjustment; (2) Luminous intensity: 5580501007F delivers 70mcd versus 2mcd, resulting in significantly higher brightness; (3) Lens transparency: 5580501007F features clear lens versus diffused lens; (4) Wire lead length: 5580501007F includes 14-inch leads versus 9-inch leads; (5) Wavelength: 5580501007F peak wavelength is 565nm versus 568nm. Forward voltage remains identical at 2.1V, and panel cutout dimensions are compatible.

Q: Is 5580501007F suitable for applications requiring the same brightness as PM3GDLW9?

A: No. The 5580501007F delivers 70mcd luminous intensity compared to 2mcd for PM3GDLW9, representing a 35-fold increase in brightness. This part is suitable only for applications where higher brightness is required or acceptable. The clear lens transparency also differs from the diffused lens of PM3GDLW9, affecting light distribution characteristics.

Q: What packaging formats are available for these substitutes?

A: PM3GDLW9 is supplied in bag packaging. PM3GDLW9.0 is supplied in bag packaging. 5580501007F is supplied in bulk packaging. Packaging format selection depends on procurement volume and inventory management requirements.

Q: Are both substitute parts RoHS compliant?

A: PM3GDLW9.0 is ROHS3 compliant. 5580501007F is ROHS3 compliant. The original PM3GDLW9 RoHS status is not specified in available documentation.

Q: Can the 14-inch wire leads of 5580501007F be trimmed to 9 inches to match PM3GDLW9?

A: Wire lead length modification is a mechanical operation outside the scope of this engineering reference. Consult application-specific design requirements and assembly procedures before modifying component leads.

Q: What is the viewing angle specification for 5580501007F?

A: The viewing angle for 5580501007F is not specified in available documentation. PM3GDLW9 specifies 40° viewing angle. Confirm viewing angle requirements with the component manufacturer if this parameter is critical for the application.
