PMR4YD LED Panel Indicator Yellow 2V Equivalent & Substitute Parts

Part Overview

The PMR4YD is a yellow LED panel indicator manufactured by Bivar Inc., designed for 2V applications with a 150mA maximum current rating. This component features a diffused lens with a 120° viewing angle and is housed in a rectangular package with PC pin termination. The PMR4YD is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PMR4YD are identified based on strict electrical and mechanical compatibility criteria. The following parameters must remain constant across all substitute candidates:

Mandatory Matching Parameters:

• Voltage rating: 2V
• Maximum current: 150mA
• Panel cutout dimensions: 0.22" x 0.14" (5.59mm x 3.56mm)
• Lens size: 2.10mm x 4.00mm
• Lens style: Rectangle with Flat Top
• Lens transparency: Diffused
• Viewing angle: 120°
• Termination style: PC Pin
• Millicandela rating: 6mcd
• Series: PMR4

The PMR4AD qualifies as a substitute part because it maintains all mandatory electrical and mechanical parameters. The primary difference is the lamp color (amber versus yellow) and wavelength specification (605nm versus 590nm), which represents a variation within the same product family designed for different visual indication requirements.

Engineering Selection Recommendations

The PMR4AD serves as a direct substitute for the obsolete PMR4YD based on identical electrical ratings and mechanical dimensions. The PMR4AD maintains active product status with Bivar Inc., ensuring continued availability and supply chain reliability. The PMR4AD carries ROHS3 compliance certification, providing environmental regulatory alignment for new designs and manufacturing processes.

Selection of the PMR4AD as a replacement component requires evaluation of the visual indication requirement. The amber wavelength (605nm) differs from the yellow wavelength (590nm) of the original PMR4YD. This wavelength difference may affect visual perception in the application context and should be assessed against system requirements for indicator color consistency and operator recognition protocols.

Both components share identical electrical parameters (2V, 150mA), mechanical form factor (0.22" x 0.14" panel cutout), and optical characteristics (120° viewing angle, 6mcd brightness, diffused lens). The PC pin termination and moisture sensitivity rating remain constant, ensuring compatibility with existing PCB layouts and environmental operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the PMR4AD directly replace the PMR4YD in existing applications?

A: The PMR4AD provides electrical and mechanical compatibility with the PMR4YD. Both components operate at 2V with 150mA maximum current, share identical panel cutout dimensions (0.22" x 0.14"), and feature the same lens size, style, and viewing angle. The primary consideration is the color difference: amber (605nm) versus yellow (590nm). Substitution is feasible if the application does not require specific yellow wavelength characteristics for operator indication or system color coding.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: voltage rating (2V), maximum current (150mA), panel cutout dimensions (0.22" x 0.14"), lens size (2.10mm x 4.00mm), lens style (rectangle with flat top), lens transparency (diffused), viewing angle (120°), termination style (PC pin), and brightness rating (6mcd). All these parameters must match between the original and substitute component.

Q: Why is the PMR4YD classified as obsolete?

A: The PMR4YD is listed as obsolete by the manufacturer. The PMR4AD, classified as active, represents the current production alternative within the PMR4 series. Procurement of new inventory should prioritize the PMR4AD for long-term supply chain stability.

Q: Are there environmental or compliance differences between these components?

A: The PMR4AD carries ROHS3 compliance certification. Both components share identical moisture sensitivity levels (MSL 1 - Unlimited) and ECCN/HTSUS classifications. The PMR4AD's ROHS3 status aligns with current environmental regulations for electronic component manufacturing and distribution.

Q: What is the impact of the wavelength difference on system performance?

A: The wavelength difference (590nm yellow versus 605nm amber) affects the perceived color of the indicator light. Both wavelengths fall within the yellow-amber spectrum range. The 6mcd brightness rating remains identical, so luminous intensity is unchanged. Application-specific requirements for color consistency or operator recognition should guide the substitution decision.

Q: Are the packaging and inventory considerations different?

A: The PMR4YD inventory shows 1015 pieces available as new original stock. The PMR4AD shows 1049 pieces available with bag packaging. The PMR4AD's active status and higher inventory level provide better long-term procurement availability compared to the obsolete PMR4YD.
