LED Panel Indicator MPR3RCW12.0 Equivalent & Substitute Parts

Part Overview

The MPR3RCW12.0 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 MPR3RCW12.0 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 eligibility for the MPR3RCW12.0 is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Manufacturer: Bivar Inc.
• Series: MPR3
• Lamp Color: Red
• Forward Voltage (Vf): 2.1V
• Maximum Current (If): 20mA
• Lens Size: 3mm, T-1
• Panel Cutout Shape and Dimensions: Round, 0.24" (6.10mm)
• Termination Style: Wire Leads - 12" (304.80mm)
• Wavelength - Peak: 700nm

Allowable Variation Parameters:

• Lens Color: May differ (clear, diffused, or tinted)
• Lens Transparency: May differ (clear or diffused)
• Viewing Angle: May differ within product line
• Millicandela Rating: May differ based on lens transparency
• Product Status: Active status preferred for ongoing availability

The MPR3RDW12.0 qualifies as a substitute based on matching all mandatory parameters while varying in lens color, lens transparency, viewing angle, and millicandela rating.

Parameter Comparison

Engineering Selection Recommendations

The MPR3RDW12.0 is the qualified substitute for the obsolete MPR3RCW12.0. Selection of this substitute is supported by the following factors:

Product Status: The MPR3RDW12.0 maintains Active product status, ensuring continued availability and supply chain support compared to the Obsolete status of the original part.

Electrical Compatibility: Both parts operate at identical forward voltage (2.1V) and maximum current (20mA) specifications, ensuring direct compatibility with existing circuit designs without modification to current-limiting resistor values or power supply requirements.

Mechanical Compatibility: Panel cutout dimensions, lens size, and termination style are identical, permitting direct physical substitution without panel redesign or wiring modifications.

Regulatory Compliance: Both parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, maintaining compliance with export control and tariff requirements. The MPR3RDW12.0 carries ROHS3 Compliant and REACH Unaffected certifications, meeting current environmental standards.

Optical Differences: The MPR3RDW12.0 features a diffused red lens compared to the clear colorless lens of the MPR3RCW12.0. This results in a reduced viewing angle (20° versus 35°) and lower millicandela rating (2mcd versus 2.5mcd). These differences affect light distribution and intensity but do not impact electrical circuit operation. Applications requiring the original 35° viewing angle or 2.5mcd intensity must evaluate whether the reduced optical performance is acceptable for the intended signaling function.

Frequently Asked Questions (FAQ)

Q: Can the MPR3RDW12.0 be used as a direct replacement for the MPR3RCW12.0 in all applications?

A: The MPR3RDW12.0 is electrically and mechanically compatible with the MPR3RCW12.0. However, the diffused red lens produces different optical characteristics: a narrower 20° viewing angle compared to 35°, and lower brightness (2mcd versus 2.5mcd). Applications requiring the original viewing angle or brightness specifications must evaluate whether these differences affect system performance.

Q: What are the key differences between these two parts?

A: The primary differences are lens characteristics. The MPR3RCW12.0 has a clear colorless lens with 35° viewing angle and 2.5mcd brightness. The MPR3RDW12.0 has a diffused red lens with 20° viewing angle and 2mcd brightness. All electrical parameters, mechanical dimensions, and termination specifications are identical.

Q: Are there any compliance or certification differences?

A: The MPR3RDW12.0 includes ROHS3 Compliant and REACH Unaffected certifications. Both parts share identical ECCN and HTSUS classifications. The substitute meets current environmental and export control requirements.

Q: Does the diffused lens affect circuit operation?

A: No. The diffused lens is an optical property that affects light distribution and appearance, not electrical circuit behavior. Forward voltage, maximum current, and all electrical characteristics remain identical.

Q: What is the inventory status of the substitute part?

A: The MPR3RDW12.0 is currently in Active product status with 1112 pieces available in stock, compared to the Obsolete MPR3RCW12.0 with 1025 pieces remaining inventory.

Q: Can I use the MPR3RDW12.0 in applications where viewing angle is critical?

A: The reduced viewing angle (20° versus 35°) may limit visibility in applications requiring wide-angle indication. Evaluate the specific viewing angle requirements of your application before substitution.
