PM5GT LED Panel Indicator Equivalent & Substitute Parts

Part Overview

The PM5GT is a green LED panel indicator manufactured by Bivar Inc., designed for panel-mount applications with wire termination. This component features a 5mm T-1 3/4 lens with a clear dome top, operating at 2.1V with a maximum current of 30mA and a brightness rating of 40mcd at a 568nm wavelength. The PM5GT is classified as obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PM5GT is determined by strict alignment of electrical and mechanical parameters. The following criteria establish compatibility:

Electrical Compatibility Requirements:

• Forward voltage (Vf) must be 2.1V
• Maximum current (If Max) must be 30mA
• Peak wavelength must be 568nm (green spectrum)

Mechanical Compatibility Requirements:

• Lens size must be 5mm, T-1 3/4
• Panel cutout shape must be Round
• Panel cutout dimensions must be 0.25" (6.35mm)
• Lens style must be Round with Domed Top

Acceptable Variation Parameters:

• Lens transparency (Clear or Diffused)
• Millicandela rating (brightness)
• Viewing angle
• Product status (Active or Obsolete)

The PM5GD meets all mandatory electrical and mechanical compatibility criteria and is classified as an active substitute for the obsolete PM5GT.

Parameter Comparison

Engineering Selection Recommendations

PM5GD as Primary Substitute for PM5GT:

The PM5GD is the direct substitute for the obsolete PM5GT. Both components share identical electrical specifications (2.1V, 30mA, 568nm wavelength) and mechanical form factors (5mm T-1 3/4 lens, 0.25" round panel cutout). The PM5GD is manufactured by the same supplier (Bivar Inc.) within the same PM5 series.

Compliance Status:

The PM5GD holds active product status with ROHS3 compliance and REACH unaffected designation, providing regulatory assurance for new designs and system replacements. The PM5GT, being obsolete, lacks current compliance documentation.

Optical Performance Differences:

The PM5GD features a diffused lens transparency compared to the clear lens of the PM5GT, resulting in a lower brightness rating (25mcd versus 40mcd) but a wider viewing angle (45° versus 35°). These optical variations are acceptable substitution parameters when the application does not require the specific brightness or viewing angle of the original component.

Inventory Availability:

The PM5GD maintains higher inventory availability (1,604 pieces) compared to the PM5GT (984 pieces), supporting supply chain continuity for ongoing production and maintenance requirements.

Frequently Asked Questions (FAQ)

Q: Can the PM5GD directly replace the PM5GT in existing applications?

A: The PM5GD is electrically and mechanically compatible with the PM5GT. Both components operate at 2.1V with 30mA maximum current and share identical mechanical form factors. The primary differences are lens transparency (diffused versus clear) and brightness rating (25mcd versus 40mcd). Substitution is valid when these optical variations do not conflict with application requirements.

Q: What is the impact of the diffused lens on system performance?

A: The diffused lens of the PM5GD scatters light over a wider viewing angle (45° versus 35°) while reducing peak brightness from 40mcd to 25mcd. Applications requiring high brightness at narrow viewing angles should evaluate whether the 25mcd output meets minimum visibility requirements.

Q: Are there packaging differences between PM5GT and PM5GD?

A: The PM5GT packaging is listed as unspecified, while the PM5GD is supplied in bag packaging. Both components maintain identical electrical and mechanical specifications, with packaging differences not affecting functional compatibility.

Q: What compliance certifications apply to the PM5GD?

A: The PM5GD is ROHS3 compliant and REACH unaffected. The PM5GT, being obsolete, does not carry current compliance documentation. For new designs or systems requiring regulatory compliance, the PM5GD is the appropriate selection.

Q: Is the PM5GD the only substitute available for the PM5GT?

A: Based on the provided substitute list, the PM5GD is the identified equivalent part. Substitution is limited to components meeting all mandatory electrical (2.1V, 30mA, 568nm) and mechanical (5mm T-1 3/4, 0.25" round cutout) specifications.

Q: Can the PM5GT and PM5GD be used interchangeably in series or parallel circuits?

A: Both components share identical forward voltage (2.1V) and maximum current (30mA) specifications, supporting equivalent circuit behavior. Interchangeability in series or parallel configurations depends on circuit design requirements and the optical performance differences noted above.
