PM5GDW18 Equivalent & Substitute Parts

Part Overview

The PM5GDW18 is a panel-mount LED indicator manufactured by Bivar Inc., featuring a 5mm green diffused lens with 18-inch wire leads. This component is classified as obsolete, indicating it is no longer in active production. The PM5GDW18 operates at 2.1V forward voltage with a maximum current rating of 30mA and delivers 25 millicandela luminous intensity at a peak wavelength of 568nm.

Due to its obsolete status, locating original stock may present supply chain challenges. Active equivalent alternatives are available that maintain identical electrical and mechanical specifications, ensuring direct functional replacement without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PM5GDW18 is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must remain identical for direct substitution:

• Electrical Specifications: Forward voltage (2.1V), maximum current (30mA), and luminous intensity (25mcd)
• Optical Characteristics: Green lamp color, diffused lens transparency, 568nm peak wavelength, and 45° viewing angle
• Mechanical Specifications: 5mm T-1 3/4 lens size, round domed-top lens style, 0.25" (6.35mm) round panel cutout, and 18-inch wire lead termination
• Environmental Rating: Moisture Sensitivity Level 1 (Unlimited)

Parts meeting all these criteria are classified as direct equivalents and may be selected interchangeably in applications requiring the PM5GDW18.

Parameter Comparison

Engineering Selection Recommendations

The PM5GDW18.0 is the direct equivalent substitute for the obsolete PM5GDW18. Both components are manufactured by Bivar Inc. and maintain identical electrical, optical, and mechanical specifications across all critical parameters.

The primary distinction between these parts is product status: PM5GDW18 is obsolete, while PM5GDW18.0 is active and currently in production. The PM5GDW18.0 carries ROHS3 compliance certification, meeting current environmental regulatory requirements for electronic components.

For new designs or component replenishment, PM5GDW18.0 is the appropriate selection due to its active production status and regulatory compliance. Existing applications using PM5GDW18 may transition to PM5GDW18.0 without circuit modification, as all functional parameters remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can PM5GDW18.0 replace PM5GDW18 in existing applications?

A: Yes. PM5GDW18.0 is a direct equivalent with identical electrical ratings (2.1V, 30mA), optical characteristics (green diffused, 25mcd, 568nm), and mechanical specifications (5mm lens, 0.25" panel cutout, 18-inch wire leads). No circuit redesign is required.

Q: What is the primary reason to substitute PM5GDW18?

A: PM5GDW18 is classified as obsolete and no longer in active production. PM5GDW18.0 is the active equivalent available for current procurement and future applications.

Q: Are there packaging differences between PM5GDW18 and PM5GDW18.0?

A: PM5GDW18 is listed with packaging designation "-" (not specified), while PM5GDW18.0 is supplied in Bag packaging. This difference does not affect component functionality or electrical performance.

Q: Does PM5GDW18.0 meet current regulatory standards?

A: Yes. PM5GDW18.0 is ROHS3 compliant, meeting current environmental and hazardous substance restrictions for electronic components.

Q: Are the optical specifications identical between these parts?

A: Yes. Both components feature green diffused lenses with 25mcd luminous intensity, 568nm peak wavelength, and 45° viewing angle. Optical performance is equivalent.

Q: What is the panel mounting compatibility?

A: Both parts require a 0.25" (6.35mm) round panel cutout and accommodate the 5mm T-1 3/4 lens form factor. Panel mounting is directly compatible.
