Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the MV6451 is based on the following allowed parameters:

Mechanical Compatibility: All substitute parts maintain the T-1 3/4 through-hole package format with radial configuration, ensuring direct mechanical interchangeability in PCB layouts designed for the MV6451.

Optical Compatibility: All substitutes share green color, diffused lens transparency, and peak wavelength of 565nm, preserving the visual indication function across the product family.

Electrical Compatibility Criteria: Substitutes are grouped by forward voltage specification. The MV6451 operates at 2.3V and is directly substitutable with the HLMP-3507 (2.1V forward voltage). The 4302H5-5V and 4302H5-12V variants operate at higher voltage levels and are suitable only for applications designed for 5V or 12V LED circuits respectively.

Brightness Variation: Millicandela ratings differ across the substitute group (MV6451: 12mcd, 4302H5 series: 8mcd, HLMP-3507: 4.2mcd). Selection must account for application brightness requirements.

Compliance: All parts maintain RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (Low Voltage Applications): The HLMP-3507 from Broadcom Limited is the closest electrical equivalent to the MV6451, with a forward voltage of 2.1V compared to 2.3V. Both parts are active products with full RoHS3 compliance. The HLMP-3507 operates at lower test current (10mA versus 20mA) and produces lower brightness (4.2mcd versus 12mcd). Selection of HLMP-3507 is appropriate when the application circuit is designed for low-voltage LED operation and brightness reduction is acceptable.

5V Circuit Applications: The 4302H5-5V from Visual Communications Company is specified for 5V forward voltage applications. This part maintains the T-1 3/4 package format and diffused green lens characteristics. The 4302H5-5V operates at 12mA test current with 8mcd brightness output. This substitute is suitable for designs incorporating 5V LED supply rails.

12V Circuit Applications: The 4302H5-12V from Visual Communications Company is specified for 12V forward voltage applications. This part maintains mechanical and optical compatibility with the MV6451 while operating at 13mA test current with 8mcd brightness output. This substitute is suitable for designs incorporating 12V LED supply rails.

Height Consideration: The MV6451 has a maximum height of 8.89mm, while both 4302H5 variants measure 10.08mm maximum height. The HLMP-3507 measures 9.19mm maximum height. PCB layout clearance must be verified when substituting with taller components.

Viewing Angle Consideration: The MV6451 provides a 70° viewing angle, while all substitute parts provide 60° viewing angle. Applications requiring wider light distribution should account for this reduction.

Frequently Asked Questions (FAQ)

Q: Can the HLMP-3507 replace the MV6451 in a 2.3V circuit?

A: The HLMP-3507 has a forward voltage of 2.1V, which is within the low-voltage LED category. Direct circuit replacement is mechanically and optically compatible. However, the HLMP-3507 produces 4.2mcd brightness compared to the MV6451's 12mcd, and operates at 10mA test current versus 20mA. Circuit design must accommodate these electrical and brightness differences.

Q: Are the 4302H5-5V and 4302H5-12V interchangeable with the MV6451?

A: The 4302H5-5V and 4302H5-12V are not electrically interchangeable with the MV6451 in circuits designed for 2.3V operation. These parts are specified for 5V and 12V applications respectively. They maintain mechanical compatibility (T-1 3/4 through-hole package) and optical compatibility (green diffused lens, 565nm peak wavelength) but require circuits designed for their respective voltage levels.

Q: What is the impact of height differences between these parts?

A: The MV6451 has a maximum height of 8.89mm. The HLMP-3507 measures 9.19mm, and the 4302H5 variants measure 10.08mm. When substituting with taller components, verify that PCB layout provides adequate clearance above the LED to prevent mechanical interference with other components or enclosure elements.

Q: Do all these parts have the same viewing angle?

A: No. The MV6451 provides a 70° viewing angle, while the HLMP-3507, 4302H5-5V, and 4302H5-12V all provide 60° viewing angles. Applications requiring wide-angle light distribution should account for this reduction when substituting.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The MV6451, HLMP-3507, 4302H5-5V, and 4302H5-12V are all RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: Which substitute part has the highest brightness?

A: The MV6451 itself has the highest brightness at 12mcd. Among the substitutes, the 4302H5-5V and 4302H5-12V both provide 8mcd brightness, while the HLMP-3507 provides 4.2mcd brightness.
