PM5HD LED Panel Indicator

Part Overview

The PM5HD is an active LED panel indicator manufactured by Bivar Inc., classified as a T-1 3/4 (5mm) red diffused lens assembly with panel mount termination. This component is designed for visual status indication applications requiring a 2V operating voltage with 30mA maximum current and 25mcd light output at 625nm peak wavelength. Finding alternative components becomes necessary when primary inventory availability is limited, when application requirements demand different electrical characteristics, or when sourcing from multiple suppliers is preferred for supply chain resilience.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the PM5HD is determined by electrical and mechanical parameter alignment. The critical parameters that govern substitute part selection are:

• Physical Form Factor: Panel cutout dimensions (0.25" / 6.35mm round) and lens size (5mm T-1 3/4) must match to enable mechanical installation without redesign
• Lens Characteristics: Diffused red lens color and round domed top style ensure visual compatibility
• Electrical Parameters: Forward voltage tolerance (2V nominal with acceptable range), maximum current rating, and millicandela output determine functional equivalence
• Light Emission: Wavelength in the red spectrum (625nm peak reference) and viewing angle performance
• Regulatory Compliance: RoHS3 and REACH status must be equivalent or better

The substitute part Dialight 5592101001F shares the same mechanical envelope, diffused red lens configuration, and regulatory compliance status. Electrical variations in forward voltage (2.2V vs. 2V), maximum current (20mA vs. 30mA), and millicandela output (6.3mcd vs. 25mcd) represent functional differences that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both PM5HD and 5592101001F maintain active product status with identical RoHS3 compliance and REACH unaffected designation. The selection between these components should be based on the specific electrical operating conditions and light output requirements of the application.

The PM5HD provides higher millicandela output (25mcd) at lower forward voltage (2V) with higher maximum current capability (30mA). This configuration is suitable for applications requiring higher luminous intensity or where the lower forward voltage aligns with existing power supply architecture.

The 5592101001F operates at a higher forward voltage (2.2V) with reduced maximum current (20mA) and lower light output (6.3mcd). The wider viewing angle (50° vs. 45°) may provide advantages in applications where light distribution across a wider field of view is beneficial. The different wavelength (650nm vs. 625nm) represents a minor shift within the red spectrum that is unlikely to affect visual perception in most indicator applications.

Both components share mechanical compatibility, regulatory certification equivalence, and unlimited moisture sensitivity rating, enabling direct substitution from a supply chain perspective. Selection should prioritize circuit voltage requirements, desired luminous intensity, and current budgets within the design.

Frequently Asked Questions (FAQ)

Q: Can the 5592101001F directly replace the PM5HD in an existing design? A: Mechanical installation is compatible due to identical panel cutout dimensions (0.25" round) and lens form factor (5mm T-1 3/4). Electrical compatibility depends on the application's forward voltage tolerance and brightness requirements. The 2.2V forward voltage of the 5592101001F versus the 2V of the PM5HD requires circuit evaluation. The significantly lower light output of the 5592101001F (6.3mcd vs. 25mcd) may be unsuitable if high visibility is required.

Q: What are the key electrical differences between these parts? A: The PM5HD operates at 2V typical forward voltage with 30mA maximum current and 25mcd output. The 5592101001F requires 2.2V forward voltage with 20mA maximum current and 6.3mcd output. Circuit design must accommodate these voltage and current variations, particularly in series resistor calculations and current-limiting stage design.

Q: Are both parts RoHS and REACH compliant? A: Both the PM5HD and 5592101001F are ROHS3 compliant and REACH unaffected, meeting current environmental regulatory requirements for component selection in most jurisdictions.

Q: How do the wavelengths differ and does this affect application performance? A: The PM5HD operates at 625nm peak wavelength (pure red) while the 5592101001F operates at 650nm (red-orange shift). Both wavelengths fall within the red spectrum and are visually similar to the human eye. Selection between them should be based on specific color coordinate requirements if the application includes chromaticity specifications.

Q: What is the significance of the viewing angle difference? A: The PM5HD provides a 45° viewing angle while the 5592101001F provides 50°. The 5° additional viewing angle on the 5592101001F results in light distribution across a slightly wider field of view. For applications requiring light observation from extreme angles, the broader viewing angle may be beneficial. For applications requiring more directional light output, the narrower 45° angle of the PM5HD may be preferable.

Q: Do both parts have the same packaging availability? A: The PM5HD is supplied in bag packaging while the 5592101001F is supplied in bulk packaging. Packaging selection may influence procurement quantities and inventory management strategies.
