MV8317 Yellow LED T-1 3/4 Through Hole - Equivalent & Substitute Parts

Part Overview

The MV8317 is a yellow LED indicator in T-1 3/4 (5mm) through-hole package manufactured by onsemi. This discrete 2.1V radial LED delivers 5500mcd at 20mA test current with a 12° viewing angle and 590nm peak wavelength. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications requiring yellow LED indication functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MV8317 is determined by the following critical parameters:

• Color: Yellow (all substitutes must be yellow)
• Lens Size: 5mm, T-1 3/4 form factor
• Lens Transparency: Clear
• Mounting Type: Through Hole radial configuration
• Voltage - Forward (Vf): 2.0V to 2.2V range
• Current - Test: 20mA
• Millicandela Rating: 5200mcd to 6000mcd range
• Wavelength - Peak: 583nm to 591nm range
• Height (Max): 8.60mm to 8.90mm range
• Package / Case: Radial

Parts meeting these criteria are electrically and mechanically compatible for direct substitution in applications designed for the MV8317.

Parameter Comparison

Engineering Selection Recommendations

Primary Equivalent (Parametric Match): MV8317 manufactured by Fairchild Semiconductor provides identical electrical and mechanical specifications to the original onsemi part. This parametric equivalent maintains 5500mcd brightness, 2.1V forward voltage, 12° viewing angle, and 590nm peak wavelength. Fairchild's version is ROHS3 compliant and currently active in production.

Direct Substitutes (Active Production):

SLI-570YT3F and SLI-570Y2T3F (Rohm Semiconductor) match the MV8317 in forward voltage (2.1V), peak wavelength (591nm), and millicandela rating (5200mcd). Both are ROHS3 compliant and actively manufactured. The wider 20° viewing angle differs from the original 12° specification.

WP7113SYCK/J3 (Kingbright) delivers 6000mcd brightness with 2V forward voltage and 590nm wavelength. ROHS3 compliant and actively produced. The 20° viewing angle and slightly lower height (8.60mm) represent minor deviations from original specifications.

OVLGY0C9B9 (TT Electronics/Optek Technology) provides the highest brightness at 14000mcd with 2V forward voltage and 589nm wavelength. ROHS3 compliant and actively manufactured. The narrower 8° viewing angle and higher brightness may require circuit evaluation for applications sensitive to luminous intensity.

Limited Compatibility: 5219466F (Dialight) operates at 2.2V forward voltage with significantly reduced brightness (140mcd) and wider 24° viewing angle. Mechanical dimensions (4.83mm lens diameter) deviate from standard 5mm T-1 3/4 form factor. This part is suitable only for applications where reduced brightness is acceptable and mechanical fit is verified.

All substitute parts maintain through-hole radial mounting, clear lens transparency, and yellow color specification. Selection should be based on application requirements for brightness, viewing angle, and forward voltage tolerance.

Frequently Asked Questions (FAQ)

Q: Can I directly replace MV8317 with any of these substitute parts? A: Yes, all listed parts are mechanically and electrically compatible for through-hole radial mounting. However, verify that your circuit design accommodates the specific forward voltage (2.0V to 2.2V range) and brightness level (140mcd to 14000mcd range) of the selected substitute.

Q: What is the difference between the Rohm SLI-570YT3F and SLI-570Y2T3F? A: Both parts share identical electrical specifications (2.1V, 5200mcd, 591nm). The primary difference is lens size: SLI-570YT3F is specified as 5mm T-1 3/4, while SLI-570Y2T3F is 5.00mm diameter. Both are mechanically compatible with the MV8317 footprint.

Q: Why does OVLGY0C9B9 have such high brightness (14000mcd)? A: OVLGY0C9B9 is designed for applications requiring high luminous intensity. The 14000mcd rating at 20mA test current is a design characteristic of this part. Applications using the original 5500mcd MV8317 should evaluate whether this increased brightness is suitable or if current-limiting adjustments are necessary.

Q: Is the Dialight 5219466F a suitable replacement? A: 5219466F operates at different electrical parameters (2.2V forward voltage, 140mcd brightness) and has a slightly smaller lens diameter (4.83mm vs. 5mm). This part is suitable only for applications where reduced brightness is acceptable and mechanical fit has been verified in the PCB layout.

Q: What does "T-1 3/4" mean? A: T-1 3/4 refers to the lens diameter specification in eighths of an inch. T-1 3/4 equals 5mm diameter, the standard form factor for these through-hole LED packages.

Q: Are all substitute parts RoHS compliant? A: Yes, all active production substitutes (Rohm, Kingbright, TT Electronics, Fairchild) are ROHS3 compliant. The original onsemi MV8317 RoHS status is not specified in available documentation.

Q: What viewing angle should I select? A: The original MV8317 has a 12° viewing angle. Substitutes range from 8° (narrower, more directional) to 24° (wider, more diffuse). Select based on your application's visibility requirements. Narrower angles concentrate light intensity; wider angles distribute it across a larger area.

Q: Can I use these parts interchangeably in the same circuit? A: Interchangeability depends on circuit design. All parts operate within 2.0V to 2.2V forward voltage range and 20mA test current. However, brightness variations (140mcd to 14000mcd) may require circuit evaluation. Verify that your current-limiting resistor and power supply accommodate the selected part's specifications.
