MPC3RCW12.0 LED Panel Indicator - Equivalent & Substitute Parts

Part Overview

The MPC3RCW12.0 is a red LED panel indicator manufactured by Bivar Inc., designed for visual signaling applications requiring a 2.1V forward voltage and 20mA maximum current. This component features a clear lens with a 3mm T-1 form factor and 12-inch wire leads for direct panel mounting through a 0.24-inch round cutout.

The MPC3RCW12.0 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPC3RCW12.0 is based on electrical and mechanical compatibility within the MPC3 series from Bivar Inc. The following parameters must remain constant or compatible for direct substitution:

Critical Parameters (Must Match):

• Forward Voltage: 2.1V
• Maximum Current: 20mA
• Lens Size: 3mm, T-1
• Panel Cutout Shape and Dimensions: 0.24" (6.10mm) Round
• Termination Style: Wire Leads - 12" (304.80mm)
• Wavelength - Peak: 700nm
• Lamp Color: Red

Variable Parameters (Allowed to Differ):

• Lens Color (Clear vs. Diffused)
• Lens Transparency
• Viewing Angle
• Millicandela Rating
• Product Status

The MPC3RDW12.0 qualifies as a substitute based on matching all critical electrical and mechanical parameters while differing only in lens optical characteristics.

Parameter Comparison

Engineering Selection Recommendations

MPC3RDW12.0 as Primary Substitute:

The MPC3RDW12.0 is the qualified substitute for the obsolete MPC3RCW12.0. Both components share identical electrical ratings (2.1V forward voltage, 20mA maximum current) and mechanical specifications (3mm T-1 lens, 0.24-inch round panel cutout, 12-inch wire leads).

The MPC3RDW12.0 is currently in active product status with full inventory availability (849 pieces in stock), ensuring supply chain continuity. The component is RoHS3 compliant and REACH unaffected, meeting current regulatory requirements.

The primary difference between the two parts is optical: the MPC3RDW12.0 features a red diffused lens with a 20° viewing angle and 2mcd brightness, compared to the MPC3RCW12.0's clear colorless lens with a 35° viewing angle and 2.5mcd brightness. This optical difference affects light distribution and intensity but does not impact electrical circuit compatibility or panel mounting.

Selection between these parts should be based on the specific visual signaling requirements of the application, particularly regarding desired light diffusion, viewing angle, and brightness intensity.

Frequently Asked Questions (FAQ)

Q: Can the MPC3RDW12.0 directly replace the MPC3RCW12.0 in existing circuit designs?

A: Yes, from an electrical standpoint. Both components operate at identical 2.1V forward voltage and 20mA maximum current ratings. Circuit design, current-limiting resistor calculations, and power supply requirements remain unchanged. However, the optical characteristics differ, which may affect visual appearance and light distribution in the application.

Q: What is the primary difference between these two parts?

A: The MPC3RCW12.0 has a clear colorless lens providing a 35° viewing angle with 2.5mcd brightness. The MPC3RDW12.0 has a red diffused lens providing a 20° viewing angle with 2mcd brightness. Both are mechanically and electrically compatible.

Q: Will the MPC3RDW12.0 fit the same panel cutout as the MPC3RCW12.0?

A: Yes. Both components require an identical 0.24-inch (6.10mm) round panel cutout and use the same 3mm T-1 lens form factor. No panel modifications are necessary.

Q: Are there any compliance or regulatory differences between these parts?

A: The MPC3RDW12.0 is RoHS3 compliant and REACH unaffected. Both components have MSL rating of 1 (Unlimited) and share the same ECCN (EAR99) and HTSUS classification (8541.41.0000).

Q: Why is the MPC3RCW12.0 listed as obsolete?

A: The MPC3RCW12.0 is classified as obsolete by the manufacturer. The MPC3RDW12.0 remains in active production and is the recommended substitute for ongoing applications.

Q: Does the diffused lens of the MPC3RDW12.0 affect circuit operation?

A: No. The diffused lens is an optical property that affects light appearance and distribution but does not impact electrical circuit behavior, voltage drop, current draw, or any electrical parameters.
