MV8304 Yellow LED T-1 3/4 Through Hole - Equivalent & Substitute Parts

Part Overview

The onsemi MV8304 is a yellow LED indication component in T-1 3/4 (5mm) through-hole radial package, rated at 2.1V forward voltage with 1500mcd brightness. The product is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Substitute parts are selected based on matching electrical characteristics (forward voltage, test current, wavelength), mechanical compatibility (lens size, mounting type, package style), and optical performance (brightness, viewing angle) within acceptable engineering tolerances.

Substitute Part Grouping Explanation

Substitution logic is based on the following critical parameters:

Primary Matching Criteria:

Color: Yellow (589-591nm wavelength range)
Lens Size: 5mm T-1 3/4 form factor
Mounting Type: Through Hole Radial
Lens Style: Round with Domed Top, Clear
Forward Voltage: 2.0V to 2.2V range
Test Current: 20mA
Moisture Sensitivity: MSL 1 (Unlimited)

Secondary Compatibility Factors:

Millicandela Rating: 1150mcd to 7400mcd (brightness variation acceptable based on application requirements)
Viewing Angle: 8° to 30° (application-dependent selection)
Height: 8.70mm to 8.91mm (PCB clearance compatibility)
Product Status: Active preferred for long-term availability

Substitute parts are grouped into two categories: direct yellow LED replacements with matching wavelength specifications, and alternative yellow LED options with different brightness and viewing angle characteristics.

Engineering Selection Recommendations

Closest Electrical Match: SLI-570YT3F (Rohm Semiconductor) provides the most direct substitution with identical forward voltage (2.1V), matching wavelength (591nm), equivalent viewing angle (20°), and comparable brightness (5200mcd vs. 1500mcd). Product status is active with ROHS3 compliance.

Alternative with Lower Brightness: LTL2R3KSK (Lite-On Inc.) offers forward voltage within 0.05V tolerance (2.05V), peak wavelength match (591nm), and brightness within acceptable range (1150mcd). Wider viewing angle (30°) may be suitable for applications not requiring narrow beam concentration. Active product status with ROHS3 compliance.

High-Brightness Options: OVLFY3C7 and OVLGY0C9B9 (TT Electronics/Optek Technology) provide significantly higher brightness (7400mcd and 14000mcd respectively) with forward voltage within 0.1V tolerance (2V). OVLGY0C9B9 features narrow 8° viewing angle for focused indication; OVLFY3C7 offers 30° viewing angle for wider distribution. Both are active products with ROHS3 compliance.

Lower-Brightness Alternative: 5219466F (Dialight) operates at 2.2V forward voltage with substantially lower brightness (140mcd). Suitable only for applications where reduced luminous intensity is required. Active product status with ROHS3 compliance.

All substitute parts maintain through-hole radial mounting, T-1 3/4 form factor, clear domed lens, and MSL 1 moisture sensitivity rating. Selection should be based on specific application brightness and viewing angle requirements.

Frequently Asked Questions (FAQ)

Q: Can SLI-570YT3F directly replace MV8304 in existing PCB designs? A: Yes. SLI-570YT3F matches the critical parameters: identical 2.1V forward voltage, equivalent 20° viewing angle, T-1 3/4 through-hole radial package, and compatible 8.85mm height. The higher brightness (5200mcd vs. 1500mcd) is acceptable for indication applications unless the original design specifically required lower luminous intensity.

Q: What is the difference between OVLFY3C7 and OVLGY0C9B9? A: Both are yellow LEDs from TT Electronics/Optek Technology with 2V forward voltage and 589nm wavelength. OVLFY3C7 provides 7400mcd brightness with 30° viewing angle for wider light distribution. OVLGY0C9B9 provides 14000mcd brightness with 8° narrow viewing angle for concentrated indication. Selection depends on whether the application requires wide or narrow beam concentration.

Q: Are all substitute parts RoHS compliant? A: Yes. All listed substitute parts are ROHS3 compliant. The original MV8304 does not specify RoHS status but is REACH unaffected. All substitutes maintain REACH unaffected status except LTL2R3KSK, which is REACH affected.

Q: What forward voltage tolerance is acceptable for substitution? A: Substitute parts with forward voltage between 2.0V and 2.2V are electrically compatible with the MV8304 (2.1V nominal). This 0.1V tolerance range accommodates standard LED manufacturing variations and circuit design margins for 20mA test current operation.

Q: Can I use a substitute with different viewing angle? A: Yes, if the application permits. The MV8304 specifies 20° viewing angle. Substitutes with 8° (narrow) or 30° (wide) viewing angles are mechanically compatible but will alter light distribution characteristics. Narrow angles concentrate light for focused indication; wide angles distribute light over broader area. Select based on specific application requirements.

Q: What is the height significance for PCB compatibility? A: All substitute parts maintain heights between 8.70mm and 8.91mm, within 0.19mm variation from the MV8304 (8.89mm). This range is acceptable for standard through-hole PCB designs with typical component clearance specifications. Verify specific PCB layout constraints if height-critical applications exist.

Q: Why is MV8304 listed as obsolete? A: Obsolete status indicates the manufacturer (onsemi) has discontinued production. Active substitute parts from alternative manufacturers ensure continued design support and component availability for new production and field replacements.
