Substitute Part Grouping Explanation

Substitution for the MV8U03 is determined by the following critical parameters:

Primary Compatibility Criteria:

Color: Blue
Wavelength - Dominant: 470nm (±5nm tolerance acceptable)
Lens Size: 5mm, T-1 3/4
Mounting Type: Through Hole
Package / Case: Radial
Lens Style: Round with Domed Top
Lens Transparency: Clear

Secondary Compatibility Criteria:

Voltage - Forward (Vf): 3.0V to 3.6V range
Current - Test: 20mA standard
Millicandela Rating: 650mcd minimum for direct replacement; higher ratings acceptable for brightness-critical applications
Viewing Angle: 20° to 45° acceptable range

Substitute parts are grouped into two categories: direct replacements (matching all primary criteria with Vf within 0.5V of the original) and functional equivalents (matching all primary criteria with Vf variance up to 0.9V, suitable for applications with adjustable current-limiting resistors).

Engineering Selection Recommendations

Direct Replacement Category (Vf 3.0V to 3.6V):

HLMP-CB2G-UW0DD and HLMP-CB2H-UW0DD are the closest functional equivalents to the MV8U03. Both feature 3.1V forward voltage (within 0.5V of the original 3.6V), 470nm dominant wavelength, and 5200mcd brightness. These parts are active products with ROHS3 compliance. The primary difference is height: HLMP-CB2G-UW0DD at 8.90mm matches the original profile, while HLMP-CB2H-UW0DD at 12.60mm provides extended lead length for specific PCB applications.

HLMP-CB3G-TV0DD offers similar voltage characteristics (3.1V) with a wider 30° viewing angle and 4000mcd brightness, suitable for applications requiring broader light distribution.

Functional Equivalent Category (Vf 2.7V to 3.2V):

HLMP-CB1A-XY0DD and HLMP-CB1B-XY0DD deliver significantly higher brightness (9600mcd) with 3.2V forward voltage and narrower 15° viewing angle. These are suitable for high-brightness indication applications where the original 650mcd is insufficient. Height variants (8.90mm and 13.21mm) accommodate different PCB layouts.

HLMP-CB2A-VW0DD and HLMP-CB2B-VW0DD provide 5700mcd brightness with 3.2V forward voltage and 23° viewing angle, offering a balance between brightness and viewing angle. Height options (8.90mm and 12.57mm) are available.

HLMP-CB3A-UV0DD and HLMP-CB3B-UV0DD deliver 4350mcd with 3.2V forward voltage and 30° viewing angle for wide-angle indication requirements.

151053BS04500 (Würth Elektronik) operates at lower forward voltage (2.7V) with significantly higher brightness (2000mcd) and wider 45° viewing angle. This part requires circuit redesign for voltage compatibility but offers superior brightness and viewing characteristics.

All substitute parts are active products with ROHS3 compliance and REACH Unaffected status, ensuring regulatory compliance and long-term availability.

Frequently Asked Questions (FAQ)

Q: Can I use HLMP-CB1A-XY0DD as a direct replacement for MV8U03?

A: HLMP-CB1A-XY0DD is electrically compatible (3.2V forward voltage within acceptable range) and shares the same 470nm wavelength, T-1 3/4 package, and through-hole mounting. However, it delivers 9600mcd versus the original 650mcd and has a narrower 15° viewing angle versus 20°. It functions as a direct mechanical and electrical replacement but with significantly higher brightness. Circuit current-limiting resistors may require adjustment if brightness is excessive for the application.

Q: What is the voltage difference impact between MV8U03 (3.6V) and HLMP-CB2G-UW0DD (3.1V)?

A: The 0.5V difference requires adjustment of the series current-limiting resistor. For a given supply voltage, the lower forward voltage of HLMP-CB2G-UW0DD results in higher current through the resistor. Recalculate the resistor value using Ohm's law: R = (Vsupply - Vf) / Iled. For example, with a 5V supply and 20mA target current, the original MV8U03 requires a 70Ω resistor, while HLMP-CB2G-UW0DD requires a 95Ω resistor.

Q: Are all substitute parts RoHS compliant?

A: All listed substitute parts are ROHS3 compliant. The original MV8U03 does not specify RoHS status. All parts are REACH Unaffected, ensuring regulatory compliance for EU and international markets.

Q: What is the difference between HLMP-CB2G-UW0DD (8.90mm) and HLMP-CB2H-UW0DD (12.60mm)?

A: Both parts are electrically and optically identical with 3.1V forward voltage, 470nm wavelength, and 5200mcd brightness. The difference is physical height: HLMP-CB2G-UW0DD has standard 8.90mm height matching the original MV8U03 profile, while HLMP-CB2H-UW0DD has extended 12.60mm height for applications requiring longer leads or specific PCB clearance requirements.

Q: Can I use 151053BS04500 as a substitute despite its 2.7V forward voltage?

A: 151053BS04500 is mechanically and optically compatible (5mm T-1 3/4 through-hole, clear lens, blue 465nm wavelength) but requires circuit redesign due to the 0.9V lower forward voltage. The lower voltage results in higher current through the series resistor for the same supply voltage. This part is suitable only if the circuit design can accommodate the voltage difference through resistor recalculation. The significantly higher brightness (2000mcd) and wider viewing angle (45°) may exceed application requirements.

Q: Which substitute offers the closest match to MV8U03 specifications?

A: HLMP-CB2G-UW0DD provides the closest overall match with 3.1V forward voltage (0.5V difference), 470nm wavelength (identical), 5200mcd brightness (8x higher but within acceptable range for brightness-critical applications), 23° viewing angle (close to original 20°), and 8.90mm height (matching original profile). This part is recommended for direct substitution with minimal circuit modification.
