MV8U01 Equivalent & Substitute Parts

Part Overview

The onsemi MV8U01 is a blue 470nm LED indication component in T-1 3/4 through-hole radial package, rated at 3.6V forward voltage with 340mcd luminous intensity. This part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain compatibility with the original electrical specifications, mechanical form factor, and mounting requirements while meeting current component availability and compliance standards.

Engineering Selection Recommendations

Primary Substitutes (Closest Electrical Match):

HLMP-CB2A-VW0DD and HLMP-CB2G-UW0DD are the preferred substitutes. Both maintain 470nm dominant wavelength, operate within the 3.1V to 3.2V forward voltage range compatible with circuits designed for the MV8U01, and provide 5200mcd to 5700mcd luminous intensity suitable for indication applications. Both are active products with ROHS3 compliance and unlimited MSL rating. Height specifications (8.90mm) match the original form factor for standard through-hole PCB applications.

Secondary Substitutes (Acceptable Electrical Compatibility):

HLMP-CB3A-UV0DD and HLMP-CB3G-TV0DD maintain 470nm wavelength and 3.1V to 3.2V forward voltage with 4000mcd to 4350mcd intensity. These parts are suitable where slightly reduced luminous intensity is acceptable. HLMP-CB1A-XY0DD provides higher intensity (9600mcd) at 3.2V forward voltage for applications requiring increased brightness.

LTL2P3TBK5 (Lite-On Inc.) operates at 4.6V forward voltage with 2500mcd intensity and 15° viewing angle, suitable for circuits with higher voltage tolerance.

Height Consideration:

Parts with extended height specifications (HLMP-CB1B-XY0DD at 13.21mm, HLMP-CB2B-VW0DD at 12.57mm, HLMP-CB3B-UV0DD at 12.25mm) are suitable only for applications with adequate PCB clearance above the component mounting surface.

Compliance Status:

All substitute parts listed are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for new designs and production.

Frequently Asked Questions (FAQ)

Q: Can HLMP-CB1B-XY0DD replace MV8U01 in a standard through-hole PCB layout?

A: HLMP-CB1B-XY0DD has a maximum height of 13.21mm compared to the MV8U01 at 8.89mm. Substitution is possible only if the PCB design provides adequate clearance above the component. Standard through-hole designs typically accommodate 8.90mm height. Verify mechanical clearance before substitution.

Q: What is the impact of forward voltage differences between MV8U01 (3.6V) and substitute parts (3.1V to 4.6V)?

A: Forward voltage differences affect circuit current limiting resistor calculations. The MV8U01 at 3.6V requires higher series resistance than substitutes at 3.1V to 3.2V to maintain 20mA test current. Recalculate series resistor values using the substitute part's forward voltage specification. For example, a circuit designed for 3.6V will deliver higher current through a 3.2V substitute if the resistor value remains unchanged. Adjust resistor values accordingly to maintain proper LED current and prevent premature failure.

Q: Are Broadcom HLMP-CB series parts direct pin-compatible with MV8U01?

A: Yes. All HLMP-CB series parts (HLMP-CB1A-XY0DD, HLMP-CB2A-VW0DD, HLMP-CB3A-UV0DD, and variants) maintain identical T-1 3/4 radial through-hole package configuration with standard anode and cathode lead spacing. Pin compatibility is confirmed across all listed Broadcom substitutes.

Q: How does millicandela rating affect substitution suitability?

A: Millicandela rating determines luminous intensity at the specified viewing angle. The MV8U01 at 340mcd is a low-intensity indication LED. Substitute parts with higher ratings (2000mcd to 9600mcd) are suitable for the same indication function and provide increased brightness margin. Lower-intensity substitutes are not recommended as they may not meet visibility requirements in the original application.

Q: What is the significance of viewing angle differences?

A: Viewing angle defines the cone of light emission. The MV8U01 has a 20° viewing angle. Substitutes range from 15° (narrow) to 45° (wide). Narrow-angle parts (15°) concentrate light intensity in a smaller cone, suitable for focused indication. Wide-angle parts (45°) distribute light over a broader area, suitable for general visibility. Select based on the original application's viewing geometry and visibility requirements.

Q: Is 151053BS04500 from Würth Elektronik a suitable substitute despite lower forward voltage (2.7V)?

A: 151053BS04500 operates at 2.7V forward voltage, significantly lower than the MV8U01 at 3.6V. While the part meets color and form factor requirements, the voltage difference requires circuit redesign. The lower forward voltage will result in higher current through an unchanged series resistor, potentially causing LED failure. This part is suitable only for new circuit designs where the lower voltage is accommodated in the resistor calculation. Not recommended for direct replacement without circuit modification.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification. The original MV8U01 is marked as REACH Unaffected. All substitutes maintain REACH Unaffected status, confirming compliance with current environmental and hazardous substance regulations.
