MPR3YCW12.0 LED Panel Indicator - Equivalent & Substitute Parts

Part Overview

The MPR3YCW12.0 is a yellow LED panel indicator manufactured by Bivar Inc., designed for applications requiring visual status indication in 2V circuits with 30mA maximum current draw. This part features a clear colorless lens with a tight 20° viewing angle and 40mcd brightness rating. The MPR3YCW12.0 is classified as obsolete, necessitating identification of suitable alternative components for new designs and ongoing system support where inventory is limited.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete MPR3YCW12.0 is based on electrical and mechanical compatibility within the following controlled parameters: voltage rating (2V), maximum current (30mA), lamp color (yellow), peak wavelength (590nm), lens size (3mm T-1), panel cutout dimensions (0.24" / 6.10mm), and wire lead termination (12" length). The MPR3YDW12.0 meets all these fundamental substitution criteria while remaining in active production status. Secondary parameters including lens transparency, viewing angle, and brightness rating differ between the parts; however, these variations represent acceptable design trade-offs within the MPR3 series platform and do not preclude functional substitution in typical panel indicator applications.

Parameter Comparison

Engineering Selection Recommendations

The MPR3YDW12.0 provides a direct functional substitute for the obsolete MPR3YCW12.0. Both components share identical electrical ratings (2V, 30mA) and mechanical package specifications (3mm T-1 lens, 0.24" panel cutout, 12" wire leads). The MPR3YDW12.0 maintains active production status, ensuring long-term availability and supply chain reliability. The substitute part carries ROHS3 compliance certification, meeting environmental regulatory requirements for current manufacturing standards. The key trade-offs between the two parts are lens transparency (clear versus diffused) and brightness (40mcd versus 20mcd), with the substitute providing wider viewing angle coverage (35° versus 20°). These differences are inherent to the diffused lens design and represent an acceptable substitution path for applications where reduced brightness and wider dispersion characteristics align with system requirements.

Frequently Asked Questions (FAQ)

Q: Can MPR3YDW12.0 be used as a drop-in replacement for MPR3YCW12.0 in existing designs?

A: Yes. Both parts operate at identical electrical specifications (2V, 30mA) and share the same mechanical package footprint (3mm T-1 lens, 0.24" panel cutout). Wire lead length and termination style are identical. No circuit modifications are required for substitution.

Q: What is the primary difference in optical performance between these parts?

A: The MPR3YCW12.0 features a clear colorless lens with 40mcd brightness and 20° viewing angle, delivering high-intensity illumination in a narrow cone. The MPR3YDW12.0 features a diffused yellow lens with 20mcd brightness and 35° viewing angle, distributing light more broadly across a wider field of view.

Q: Why is the MPR3YCW12.0 listed as obsolete?

A: Product status reflects manufacturer discontinuation decisions. The active MPR3YDW12.0 within the same series provides functional coverage for standard panel indicator applications.

Q: Are there compliance or regulatory considerations for this substitution?

A: The MPR3YDW12.0 carries ROHS3 compliance certification. Confirm alignment with your application's environmental and regulatory requirements before final selection.

Q: How do lens transparency differences affect application suitability?

A: Clear lenses (MPR3YCW12.0) transmit the LED's native wavelength with minimal color filtering, achieving higher brightness. Diffused lenses (MPR3YDW12.0) scatter light through a tinted material, reducing brightness but improving visibility across wider angles and reducing glare in certain viewing geometries.

Q: Are panel cutout modifications required for installation?

A: No. Both parts use identical 0.24" (6.10mm) round panel cutout dimensions. Existing mechanical mounting interfaces remain compatible.
