MV8B11 Blue LED T-1 3/4 Through Hole - Equivalent & Substitute Parts

Part Overview

The MV8B11 is an obsolete blue LED indication component manufactured by onsemi, featuring a 5mm T-1 3/4 through-hole package with clear lens and 600mcd brightness rating. The part operates at 3.8V forward voltage with 20mA test current and 10° viewing angle. Due to its obsolete product status, equivalent substitute parts from active manufacturers are necessary for new designs and ongoing production requirements.

Substitute Part Grouping Explanation

Substitute parts are grouped based on strict parameter alignment with the MV8B11. The primary substitution criteria are:

Critical Parameters for Substitution:

Color: Blue
Lens Transparency: Clear
Mounting Type: Through Hole
Package / Case: Radial
Current - Test: 20mA
Lens Style: Round with Domed Top
Moisture Sensitivity Level: 1 (Unlimited)

Secondary Parameters (Allowable Variation):

Voltage - Forward (Vf): 2.7V to 3.8V range
Millicandela Rating: 600mcd minimum
Wavelength - Peak: 430nm to 472nm range
Viewing Angle: 10° to 45° range
Height (Max): 8.70mm to 13.21mm range
Lens Size: 5mm or 5mm T-1 3/4

Substitute parts must maintain identical color, lens transparency, mounting type, and package configuration. Variations in forward voltage, brightness, wavelength, and viewing angle are acceptable within the specified ranges for equivalent functionality in indication applications.

Engineering Selection Recommendations

All listed substitute parts maintain active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. The MV8B11 obsolete status necessitates transition to active alternatives.

For direct electrical compatibility: HLMP-CB1A-XY0DD and 5219946F match the 3.8V forward voltage specification of the MV8B11, minimizing circuit redesign requirements.

For brightness-critical applications: HLMP-CB1A-XY0DD (9600mcd) and HLMP-CB2A-VW0DD (5700mcd) provide significantly higher luminous intensity than the original 600mcd rating, suitable for applications requiring enhanced visibility.

For narrow viewing angle requirements: HLMP-CB1A-XY0DD (15°) and MV8B11 (10°) are closest in viewing angle specification, maintaining directional light distribution characteristics.

For standard indication applications: HLMP-CB3A-UV0DD (4350mcd, 30° viewing angle) and 5219946F (1010mcd, 30° viewing angle) provide balanced brightness and wide viewing angle for general indication purposes.

All substitute parts share identical mechanical form factor (5mm T-1 3/4 through-hole radial package), lens transparency, and MSL rating, ensuring direct PCB footprint compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can HLMP-CB1A-XY0DD directly replace MV8B11 in existing designs?

A: Yes. Both parts share identical 5mm T-1 3/4 through-hole radial package, clear lens, and 20mA test current. The HLMP-CB1A-XY0DD operates at 3.2V forward voltage compared to MV8B11's 3.8V, requiring circuit current-limiting resistor adjustment. The higher brightness (9600mcd vs 600mcd) is compatible with indication applications.

Q: What is the primary difference between 151053BS04500 and other substitutes?

A: The 151053BS04500 operates at 2.7V forward voltage, the lowest among substitutes. This requires the most significant circuit redesign for current-limiting resistor values. It offers the widest viewing angle (45°) and high brightness (2000mcd). The 5.00mm diameter lens differs slightly from T-1 3/4 specification but maintains mechanical compatibility.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant certification. The MV8B11 product status does not specify RoHS compliance. All substitutes maintain REACH Unaffected status matching the original part.

Q: Which substitute provides the closest electrical match to MV8B11?

A: The 5219946F (Dialight 521 series) matches the 3.8V forward voltage specification exactly, eliminating circuit redesign requirements. It provides 1010mcd brightness and 30° viewing angle, suitable for standard indication applications.

Q: Can I use HLMP-CB2A-VW0DD or HLMP-CB3A-UV0DD as direct substitutes?

A: Yes. Both parts operate at 3.2V forward voltage and maintain identical 5mm T-1 3/4 through-hole radial package configuration. Circuit current-limiting resistor adjustment is required due to the 0.6V voltage difference from MV8B11. HLMP-CB2A-VW0DD provides 5700mcd brightness with 23° viewing angle; HLMP-CB3A-UV0DD provides 4350mcd with 30° viewing angle.

Q: What packaging options are available for substitute parts?

A: Würth Elektronik 151053BS04500 is supplied in Bulk packaging. Dialight 5219946F is supplied in Bulk packaging. Broadcom HLMP series parts are available in Cut Tape (CT) or Tape & Box (TB) packaging depending on specific part number variant. Packaging selection does not affect electrical or mechanical compatibility.

Q: Are there height differences between MV8B11 and substitutes?

A: MV8B11 maximum height is 8.90mm. Substitute parts range from 8.70mm to 13.21mm maximum height. Standard variants (HLMP-CB1A-XY0DD, HLMP-CB2A-VW0DD, HLMP-CB3A-UV0DD) maintain 8.90mm height matching the original. Extended-height variants exist but are not required for standard applications.
