MPR3HC LED Panel Indicator Equivalent & Substitute Parts

Part Overview

The MPR3HC is a panel-mounted LED indicator manufactured by Bivar Inc., classified as an obsolete product. This red LED panel indicator features a clear lens with a 20° viewing angle, rated at 2V and 30mA, with a 50mcd brightness output at 625nm wavelength. The component utilizes a 3mm T-1 round domed lens housed in a 0.24" (6.10mm) round panel cutout.

Due to the obsolete product status of the MPR3HC, locating equivalent substitute components is necessary for ongoing system maintenance, repair, and new design implementations. Substitute parts must maintain electrical compatibility while accommodating potential differences in optical characteristics and physical termination styles.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MPR3HC are identified based on strict electrical and mechanical compatibility criteria. The following parameters must align for valid substitution:

Mandatory Matching Parameters:

• Voltage rating: 2V
• Current rating: 30mA
• Lamp color: Red
• Wavelength peak: 625nm
• Lens size: 3mm, T-1
• Panel cutout shape: Round
• Panel cutout dimensions: 0.24" (6.10mm)
• Lens style: Round with Domed Top
• Series: MPR3

Allowable Variation Parameters:

• Lens color (Clear to Diffused)
• Lens transparency (Clear to Diffused)
• Viewing angle (20° to 35°)
• Millicandela rating (30mcd to 50mcd)
• Termination style (panel mount to wire leads)
• Product status (Obsolete to Active)

The MPR3HDW12.0 qualifies as a substitute part because it maintains all mandatory electrical and mechanical parameters while offering an active product status and alternative termination configuration.

Parameter Comparison

Engineering Selection Recommendations

MPR3HC (Obsolete): The MPR3HC is classified as an obsolete product. While 990 units remain in stock, this part number is no longer actively manufactured or supported. Selection of this component is limited to applications requiring exact legacy compatibility or existing inventory utilization.

MPR3HDW12.0 (Active Substitute): The MPR3HDW12.0 is classified as an active product with 651 units in stock and carries ROHS3 compliance certification. This substitute maintains all critical electrical parameters (2V, 30mA, 625nm wavelength) and mechanical compatibility (3mm T-1 lens, 0.24" round panel cutout). The primary differences are optical characteristics (diffused lens versus clear, 30mcd versus 50mcd, 35° versus 20° viewing angle) and termination style (12" wire leads versus panel mount).

For new designs and ongoing procurement, the MPR3HDW12.0 is the recommended selection due to active product status and regulatory compliance. Applications requiring the specific optical characteristics of the MPR3HC (clear lens, 50mcd, 20° viewing angle) must evaluate whether the MPR3HDW12.0 optical differences are acceptable within system performance requirements.

Frequently Asked Questions (FAQ)

Q: Can the MPR3HDW12.0 directly replace the MPR3HC in existing panel-mounted applications?

A: The MPR3HDW12.0 provides electrical compatibility but differs in termination style. The MPR3HC features panel-mount termination, while the MPR3HDW12.0 provides 12" wire leads. Physical integration into existing panel cutouts requires adapter or rework considerations. The identical panel cutout dimensions (0.24" round) and lens size (3mm T-1) support mechanical compatibility with appropriate termination modification.

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

A: The MPR3HC features a clear colorless lens with 50mcd brightness and a 20° viewing angle. The MPR3HDW12.0 features a red diffused lens with 30mcd brightness and a 35° viewing angle. Both emit at 625nm wavelength. The diffused lens and wider viewing angle of the MPR3HDW12.0 provide broader light distribution, while the MPR3HC provides higher intensity in a narrower cone.

Q: Are both parts RoHS compliant?

A: The MPR3HC does not specify RoHS status in available documentation. The MPR3HDW12.0 carries ROHS3 compliance certification. Both parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications and identical Moisture Sensitivity Level 1 (Unlimited) ratings.

Q: What is the significance of the different millicandela ratings?

A: The MPR3HC provides 50mcd output while the MPR3HDW12.0 provides 30mcd output. Both operate at identical voltage (2V) and current (30mA) ratings. The brightness difference results from lens design and material properties. Applications requiring specific brightness levels must evaluate whether the 30mcd output of the MPR3HDW12.0 meets minimum visibility requirements.

Q: Can I use the MPR3HDW12.0 in applications originally designed for the MPR3HC?

A: Electrical compatibility is confirmed across all critical parameters (voltage, current, wavelength). Mechanical compatibility depends on termination requirements. Optical compatibility depends on whether the application can tolerate reduced brightness (30mcd versus 50mcd), wider viewing angle (35° versus 20°), and diffused lens characteristics versus clear lens. System-level evaluation is required for each application.

Q: What is the inventory status for these parts?

A: The MPR3HC has 990 units in stock with obsolete product status. The MPR3HDW12.0 has 651 units in stock with active product status. For long-term procurement planning, the active status of the MPR3HDW12.0 provides supply continuity advantages.
