Key Parameters

Substitute Part Grouping Explanation

Substitution for the HLMP-6820-F0021 is determined by the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Color: Green (569nm dominant wavelength, 565nm peak)
• Lens Transparency: Diffused
• Mounting Type: Surface Mount (2-SMD configuration)
• Current - Test: 10mA
• Lens Style: Round with Domed Top
• Height (Max): 2.92mm
• Viewing Angle: 90° (or compatible wide-angle performance)

Secondary Compatibility Factors:

• Voltage - Forward (Vf): 5V nominal (substitutes may operate at lower voltages with circuit redesign)
• Millicandela Rating: 2mcd minimum
• Lens Size: 1.78mm Dia (similar optical dimensions acceptable)
• Package / Case: 2-SMD configuration with compatible lead geometry

The identified substitute parts MV6400AGR and MV6400AZR share the core optical and mounting characteristics but operate at 2V forward voltage, requiring circuit-level voltage adjustment. Both substitutes maintain the 10mA test current, diffused green lens, and surface mount 2-SMD configuration necessary for functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

MV6400AZR (Everlight Electronics Co Ltd) is the preferred substitute for new designs and ongoing production. This part maintains active product status, ensuring long-term availability and supply chain stability. The MV6400AZR operates at 2V forward voltage with equivalent 10mA test current and diffused green optical characteristics. The Z-Bend lead configuration accommodates standard surface mount assembly processes. Moisture sensitivity level 1 (unlimited) provides superior handling and storage characteristics compared to the original MSL 2A specification.

MV6400AGR (onsemi) serves as an alternative substitute with identical electrical and optical parameters to the MV6400AZR. However, obsolete product status limits its suitability for new production applications. The Gull Wing lead configuration requires verification of PCB footprint compatibility with existing designs.

Both substitutes require circuit-level voltage adjustment due to the 5V-to-2V forward voltage reduction. Designs utilizing the HLMP-6820-F0021 at 5V operation must implement appropriate current-limiting resistor recalculation to maintain 10mA test current through the 2V substitute parts.

Frequently Asked Questions (FAQ)

Q: Can MV6400AGR or MV6400AZR be used as direct pin-for-pin replacements for HLMP-6820-F0021?

A: No. While all three parts share identical height (2.92mm), surface mount 2-SMD configuration, and 10mA test current, the lead geometries differ (Yoke Bend vs. Gull Wing vs. Z-Bend). PCB footprint verification is required before substitution. Additionally, the forward voltage reduction from 5V to 2V necessitates circuit redesign.

Q: What is the impact of the 90° viewing angle on HLMP-6820-F0021 versus the 50° viewing angle on substitute parts?

A: The original part provides a wider light distribution pattern (90°) compared to the 50° viewing angle of both substitutes. Applications requiring wide-angle indication must evaluate whether the narrower 50° beam angle is acceptable for the intended use case.

Q: Are the substitute parts RoHS compliant?

A: MV6400AZR is ROHS3 compliant. MV6400AGR compliance information is not provided in the available data. Verify RoHS status with the manufacturer for specific regulatory requirements.

Q: How does the millicandela rating difference affect substitution?

A: Both substitutes provide 3mcd brightness compared to the original 2mcd rating. This represents a 50% increase in light output. Applications sensitive to brightness levels must evaluate whether the higher intensity is acceptable or requires additional circuit-level attenuation.

Q: What are the moisture sensitivity implications of using MV6400AGR or MV6400AZR?

A: Both substitutes feature MSL 1 (Unlimited) compared to the original MSL 2A (4 Weeks). This provides superior moisture tolerance and eliminates the 4-week shelf-life constraint associated with the original part, reducing storage and handling complexity.
