PM5YC LED Panel Indicator

Part Overview

The PM5YC is a panel-mounted LED indicator from Bivar Inc., classified as an obsolete product. This yellow LED panel indicator features a clear lens with 35° viewing angle and operates at 2V with 30mA maximum current. The product is available in 854 pieces of new original stock. Due to its obsolete status, identifying compatible substitute components is essential for continued system operation and maintenance in applications currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PM5YC is evaluated based on the following critical parameters that define functional equivalence and mechanical compatibility:

Electrical Parameters:

• Voltage rating (2V) and maximum current (30mA) must match to ensure safe operation within existing circuit designs
• Wavelength peak (590nm) confirms yellow light emission across the visible spectrum

Mechanical Parameters:

• Panel cutout shape (round) and dimensions (0.25"/6.35mm) determine physical fit in panel-mounted applications
• Lens size (5mm, T-1 3/4) and lens style (round with domed top) establish form factor compatibility

Optical Parameters:

• Lamp color (yellow) defines the primary color output
• Lens transparency and viewing angle affect light diffusion and visibility characteristics
• Millicandela rating indicates brightness level

The PM5YD qualifies as a substitute based on matching electrical parameters (2V, 30mA), mechanical compatibility (round 0.25" cutout, 5mm T-1 3/4 lens), and identical wavelength (590nm), while operating in the Bivar PM5 series as an active product with enhanced availability.

Parameter Comparison

Engineering Selection Recommendations

The PM5YC is classified as an obsolete product with existing inventory of 854 pieces. The PM5YD serves as the active substitute within the Bivar PM5 series. Both components are EAR99-classified and share HTSUS code 8541.41.0000, confirming regulatory equivalence. The PM5YD maintains identical electrical specifications (2V, 30mA) and mechanical compatibility (0.25" round cutout, 5mm T-1 3/4 lens), enabling direct substitution in panel-mount applications. The PM5YD's RoHS3 compliance status provides additional environmental and regulatory assurance for new designs and long-term system support.

Differences in brightness (40mcd versus 25mcd), lens transparency (clear versus diffused), and viewing angle (35° versus 45°) reflect operational trade-offs. The PM5YD's diffused lens and broader viewing angle distribute light across a wider area with reduced peak intensity, while the PM5YC's clear lens concentrates light within a narrower 35° cone at higher brightness.

Frequently Asked Questions (FAQ)

Q: Can PM5YD replace PM5YC in existing applications? A: Yes. Both components share identical voltage (2V), current rating (30mA), panel cutout dimensions (0.25" round), and lens form factor (5mm T-1 3/4). Electrical and mechanical compatibility is maintained.

Q: What are the optical differences between PM5YC and PM5YD? A: The PM5YC delivers 40mcd through a clear lens within a 35° viewing angle. The PM5YD delivers 25mcd through a diffused yellow lens within a 45° viewing angle. The PM5YD provides wider light distribution at reduced peak brightness.

Q: Does the PM5YD's diffused lens affect panel installation? A: No. The diffused lens does not alter mechanical installation. Panel cutout dimensions, lens size, and mounting style remain identical. Only the optical appearance and light distribution characteristics differ.

Q: Are both components regulatory compliant? A: Yes. Both are EAR99-classified and share HTSUS code 8541.41.0000. The PM5YD carries RoHS3 compliance certification, supporting environmental and regulatory requirements.

Q: What is the inventory status for each component? A: PM5YC stock is 854 pieces (obsolete product). PM5YD stock is 889 pieces (active product).
