MV8B01 Blue LED T-1 3/4 Through Hole - Equivalent & Substitute Parts

Part Overview

The MV8B01 is a blue 465nm LED indication component manufactured by onsemi in a T-1 3/4 through-hole radial package. This discrete LED operates at 3.8V forward voltage with a 450mcd brightness rating and 20° viewing angle. The product is currently obsolete, making equivalent and substitute parts necessary for ongoing design support, maintenance, and production continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the MV8B01 is determined by the following critical parameters:

Primary Compatibility Criteria:

Color: Blue
Lens Size: 5mm, T-1 3/4 (or equivalent 5mm round)
Lens Style: Round with Domed Top
Lens Transparency: Clear
Mounting Type: Through Hole
Package / Case: Radial
Wavelength - Dominant: 465nm to 470nm range
Current - Test: 20mA

Secondary Compatibility Considerations:

Voltage - Forward (Vf): 2.7V to 3.8V operating range
Millicandela Rating: 450mcd minimum
Viewing Angle: 15° to 45° acceptable
Height (Max): 8.85mm to 13.21mm acceptable for standard through-hole mounting

The substitute parts listed below meet the primary criteria and operate within acceptable electrical and mechanical tolerances for direct replacement in through-hole PCB applications.

Engineering Selection Recommendations

All listed substitute parts are active products with current manufacturing status, ensuring long-term availability and supply chain stability compared to the obsolete MV8B01.

Würth Elektronik 151053BS04500: This part offers the closest wavelength match at 465nm and maintains standard 5mm through-hole form factor. The lower forward voltage (2.7V) reduces power consumption. Higher brightness (2000mcd) and wider viewing angle (45°) provide enhanced visibility. RoHS3 compliance and REACH Unaffected status meet modern regulatory requirements.

Broadcom Limited HLMP-CB Series: All Broadcom substitutes operate at 470nm wavelength with RoHS3 compliance. The series provides multiple brightness and viewing angle options:

HLMP-CB1A/CB1B: Highest brightness (9600mcd) with narrow 15° viewing angle for focused indication
HLMP-CB2A/CB2B/CB2G/CB2H: Mid-range brightness (5200-5700mcd) with 23° viewing angle for general indication
HLMP-CB3A/CB3B/CB3G: Lower brightness (4000-4350mcd) with 30° viewing angle for wide-area indication

Height variants (standard 8.90mm or extended 12-13mm) accommodate different PCB clearance requirements. Forward voltage ranges from 3.1V to 3.2V, compatible with standard 5V logic circuits.

Frequently Asked Questions (FAQ)

Q: Can I directly replace MV8B01 with any of these substitute parts?

A: Yes, all listed parts are direct mechanical and electrical replacements. They share identical 5mm T-1 3/4 through-hole radial packaging, blue color, and 20mA test current. Forward voltage differences (2.7V to 3.2V versus 3.8V) are within acceptable design margins for standard LED indicator circuits.

Q: What is the difference between the Würth Elektronik and Broadcom options?

A: The Würth Elektronik 151053BS04500 matches the MV8B01 wavelength exactly at 465nm and offers the lowest forward voltage (2.7V). Broadcom parts operate at 470nm wavelength with higher forward voltage (3.1-3.2V) but provide multiple brightness and viewing angle options through the HLMP-CB series variants.

Q: How do I choose between different Broadcom HLMP-CB variants?

A: Selection depends on application requirements. HLMP-CB1 series provides maximum brightness (9600mcd) for long-distance visibility with narrow 15° viewing angle. HLMP-CB2 series offers moderate brightness (5200-5700mcd) with 23° viewing angle for standard indicator applications. HLMP-CB3 series provides lower brightness (4000-4350mcd) with wider 30° viewing angle for close-range or high-ambient-light applications.

Q: Does height variation affect compatibility?

A: Height variants (8.90mm standard versus 12-13mm extended) are both through-hole compatible. Selection depends on available PCB clearance above the component. Standard height (8.90mm) is recommended for typical applications unless space constraints require extended height variants.

Q: Are all substitutes RoHS and REACH compliant?

A: Yes. All substitute parts carry RoHS3 compliance and REACH Unaffected status, meeting current environmental and regulatory requirements. The obsolete MV8B01 carries REACH Unaffected status but predates RoHS3 certification.

Q: What packaging options are available?

A: Würth Elektronik supplies in Bulk packaging. Broadcom supplies in Cut Tape (CT) or Tape & Box (TB) formats. Selection depends on procurement volume and handling requirements. All formats are suitable for through-hole assembly.
