Product details
Overview
MV8331 from Fairchild Semiconductor is a super-bright yellow T-1 3/4 (5 mm) LED lamp with water-clear epoxy lens, 30° viewing angle, 590 nm peak wavelength, and 400 mcd minimum luminous intensity at 20 mA - used in outdoor status indicators and industrial panel lighting.
For engineers reviewing the MV8331 datasheet, pinout, applications, or equivalent options, key selection factors include forward voltage (2.8 V max), thermal derating above 25°C, cathode identification via flat edge, and compatibility with standard 100-mil lead spacing PCB footprints.
Technical Context
This MV8331 is an AlInGaP-based yellow LED emitting at precisely 590 nm with 15 nm spectral line half-width, delivering concentrated light output via its 30° viewing angle. It operates within -40°C to +100°C ambient range and requires DC forward current ≤30 mA continuous.
The device uses a water-clear epoxy encapsulation for maximum optical transmission and features solid-state reliability with no filament or glass envelope. Its cathode is unambiguously marked by a flat edge on the LED body per JEDEC-standard T-1 3/4 package definition.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Wavelength | 590 nm - precise yellow emission matching traffic signal and warning-light color standards |
| Luminous Intensity | 400 mcd min @ 20 mA - sufficient brightness for daylight-visible status indication |
| Forward Voltage | 2.8 V max @ 20 mA - defines minimum supply headroom and series resistor sizing |
| Viewing Angle | 30° - narrow beam for directional signaling without optical diffusers |
| Operating Temp | -40°C to +100°C - supports deployment in automotive under-hood and industrial outdoor enclosures |
| Lead Spacing | 100 mil (2.54 mm) - matches standard through-hole PCB footprint for T-1 3/4 sockets |
Pinout & Package
T-1 3/4 (5 mm) radial-leaded package with flat edge denoting cathode; leads spaced 0.100" (2.54 mm) center-to-center; overall body diameter 0.200" (5.08 mm); flange-to-tip length 0.350" (8.89 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Longer Lead) | Positive DC input | Connected to current-limiting resistor; polarity must be observed to avoid reverse breakdown |
| Cathode (Flat Edge / Shorter Lead) | Ground return path | Marked by flat side of epoxy body; required for correct orientation during manual or automated placement |
Key Features
| Feature | Design Value |
|---|---|
| Water-clear epoxy lens | Maximizes luminous flux transmission without chromatic filtering or diffusion loss |
| AlInGaP semiconductor material | Enables stable 590 nm yellow output with low temperature coefficient vs. older GaAsP LEDs |
| 30° viewing angle | Concentrates light into defined zones - reduces need for external reflectors or collimators |
| 100-mil lead spacing | Ensures drop-in compatibility with legacy T-1 3/4 sockets and wave-solder tooling |

Use Value: Solid-state reliability and 30 mA max continuous current enable >50,000-hour operational lifetime at rated drive. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar yellow LED indicator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTL-307YE (Lite-On) | Same T-1 3/4 package, 585–595 nm peak, 350–550 mcd @ 20 mA | Slightly lower min intensity; identical thermal rating and viewing angle | Select when tighter binning for yellow hue is required, with minor intensity trade-off |
| TLHR5900 (Vishay) | 590 nm peak, 500 mcd min @ 20 mA, 2.6 V max VF, same 30° viewing angle | Higher min intensity and lower forward voltage reduce series resistor power dissipation | Prefer for new designs needing marginally higher brightness and improved efficiency |
Compared with MV8331, LTL-307YE offers tighter wavelength control but lower guaranteed output, while TLHR5900 delivers higher minimum intensity and lower forward voltage - both require verification of cathode marking alignment and thermal derating curves in final layout.

FAQ
What is the absolute maximum forward current rating for MV8331?
The MV8331 has an absolute maximum continuous forward current of 30 mA at TA = 25°C. Peak forward current is rated at 160 mA with 1/10 duty cycle at 1 kHz. Exceeding 30 mA continuously risks accelerated lumen depreciation and reduced lifetime. Derating is required above 25°C ambient - see Fig. 5 in the MV8331 datasheet for exact current limits per temperature.
How is cathode polarity identified on the MV8331 package?
The cathode of the MV8331 is identified by a flat edge on the epoxy lens body - a JEDEC-standard marking for T-1 3/4 LEDs. The cathode lead is also physically shorter than the anode lead. This dual marking ensures unambiguous orientation during manual soldering or automated placement, preventing reverse-bias damage during circuit operation.
Does MV8331 meet RoHS or lead-free soldering requirements?
The MV8331 was manufactured prior to full RoHS enforcement and uses leaded solder-compatible construction. Its lead finish is SnPb, and it is rated for 260°C for 5 seconds - consistent with traditional eutectic solder profiles. For RoHS-compliant alternatives, consider ON Semiconductor's NSPW500BS or Vishay's TLHR5900, both offering equivalent photometric performance in lead-free packages.
What is the typical forward voltage of MV8331 at 20 mA drive current?
The MV8331 has a typical forward voltage of 2.1 V at 20 mA and 25°C ambient temperature, with a maximum specification of 2.8 V. This 0.7 V tolerance window must be accounted for when designing the series current-limiting resistor to ensure consistent luminance across production units and temperature extremes.
Can MV8331 be used in outdoor applications exposed to UV or moisture?
Yes - the MV8331 uses water-clear epoxy encapsulation with inherent UV resistance and hermetic sealing against humidity ingress. Its -40°C to +100°C operating range and solid-state construction make it suitable for outdoor signage, traffic signals, and industrial enclosures. However, long-term UV exposure may cause gradual yellowing of non-UV-stabilized epoxy; consult Fairchild's reliability report 300017A for accelerated life test data.
