LED Panel Indicator MPR3HT Equivalent & Substitute Parts

Part Overview

The MPR3HT is a panel-mounted LED indicator manufactured by Bivar Inc., designed for applications requiring a red light-emitting diode with clear lens optics. This component features a 3mm T-1 lens form factor with 50mcd brightness output at 625nm wavelength peak, operating at 2V with 30mA maximum current. The MPR3HT is classified as obsolete product status, necessitating identification of active equivalent components for new designs and ongoing production requirements. Substitute parts must maintain electrical compatibility while accommodating mechanical and optical parameter variations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MPR3HT is determined by strict adherence to critical electrical and mechanical parameters. All substitute components must satisfy the following requirements:

Critical Parameters (Non-Negotiable):

• Voltage rating: 2V
• Maximum current: 30mA
• Lamp color: Red
• Wavelength peak: 625nm
• Lens size: 3mm, T-1 form factor
• Panel cutout shape: Round
• Panel cutout dimensions: 0.24" (6.10mm)
• Lens style: Round with domed top

Application-Dependent Parameters (Allowable Variation):

• Millicandela rating: Substitutes may vary based on application brightness requirements
• Viewing angle: Substitutes may vary based on application field-of-view requirements
• Lens transparency: Substitutes may vary (clear, diffused, or tinted) based on application optical requirements

The MPR3HDW12.0 qualifies as a substitute component because it maintains all critical electrical and mechanical parameters while offering variations in brightness (30mcd vs. 50mcd), viewing angle (35° vs. 20°), and lens transparency (diffused vs. clear). These variations are permissible when application requirements accommodate lower brightness output and wider viewing angle characteristics.

Engineering Selection Recommendations

Product Status Consideration: The MPR3HT carries obsolete product status, indicating discontinued manufacturing and limited availability. The MPR3HDW12.0 maintains active product status with confirmed inventory availability (651 pieces), establishing it as the primary substitute for ongoing production and new design implementations.

Compliance and Certification: Both components share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, confirming regulatory equivalence. The MPR3HDW12.0 includes RoHS3 compliance certification, meeting current environmental and hazardous substance restrictions applicable to electronic components.

Electrical Compatibility: The substitute component maintains identical voltage (2V) and current (30mA) specifications, ensuring direct circuit compatibility without modification to power supply or current-limiting resistor calculations.

Optical and Mechanical Compatibility: The MPR3HDW12.0 preserves all critical mechanical parameters: 3mm T-1 lens form factor, round panel cutout shape, and 0.24" (6.10mm) cutout dimensions. Panel mounting compatibility is maintained without requiring mechanical redesign.

Parameter Variation Assessment: The MPR3HDW12.0 introduces three parameter variations from the original specification:

• Brightness reduction from 50mcd to 30mcd
• Viewing angle expansion from 20° to 35°
• Lens transparency change from clear to diffused

These variations are acceptable when application requirements accommodate reduced brightness output and expanded viewing angle characteristics. Applications requiring the original 50mcd brightness or 20° narrow viewing angle must evaluate alternative components within the MPR3 series or other manufacturers' equivalent offerings.

Frequently Asked Questions (FAQ)

Q: Can the MPR3HDW12.0 directly replace the MPR3HT in existing circuit designs?

A: The MPR3HDW12.0 maintains electrical compatibility (2V, 30mA) and mechanical compatibility (3mm T-1 lens, 0.24" round cutout) with the MPR3HT. Direct substitution is possible when application brightness requirements accommodate 30mcd output instead of 50mcd, and when the expanded 35° viewing angle is acceptable compared to the original 20° specification.

Q: What is the significance of the lens transparency difference between clear and diffused?

A: The MPR3HT features a clear lens providing direct light transmission with minimal scattering, suitable for applications requiring focused light output. The MPR3HDW12.0 features a diffused lens that scatters light across a wider area, contributing to the expanded 35° viewing angle. Application requirements determine which lens transparency is appropriate.

Q: Why does the MPR3HDW12.0 have lower millicandela rating than the MPR3HT?

A: The 30mcd rating of the MPR3HDW12.0 compared to the 50mcd rating of the MPR3HT reflects the optical characteristics of the diffused lens design. Diffused lenses distribute light across a wider viewing angle, resulting in lower peak brightness at the center axis. Applications requiring the original 50mcd brightness specification must identify alternative components.

Q: Are there packaging differences between these components?

A: The MPR3HT packaging is specified as "-" (not detailed in available documentation). The MPR3HDW12.0 is packaged in bags with 12-inch wire leads included. The wire lead length and packaging format may require evaluation for compatibility with existing assembly processes and panel mounting procedures.

Q: What compliance certifications apply to the MPR3HDW12.0?

A: The MPR3HDW12.0 carries RoHS3 compliance certification, confirming adherence to current restrictions on hazardous substances in electrical and electronic equipment. Both components share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications for export and tariff purposes.

Q: Is the MPR3HDW12.0 suitable for new product designs?

A: The MPR3HDW12.0 carries active product status with confirmed inventory availability, establishing it as the appropriate component selection for new designs requiring red LED panel indicators in the 3mm T-1 form factor. The obsolete status of the MPR3HT makes the active MPR3HDW12.0 the recommended choice for ongoing production and development.

Q: What are the moisture sensitivity implications for these components?

A: Both components carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture-related storage or handling restrictions. Standard component storage practices are applicable without requiring specialized dry-pack or desiccant preservation methods.
