For engineers reviewing the TLUG2401 datasheet, TLUG2401 pinout, TLUG2401 application, or TLUG2401 equivalent, this page delivers verified optical/electrical specs, thermal limits, package geometry, brightness binning context, and direct alternative options for indicator LED selection.
Technical Context
This device is a through-hole, axial-lead, diffused-tinted green LED optimized for DC and pulsed operation. It features a 1.8 mm miniplast package with center-to-center stackable pitch of 2.54 mm and luminous intensity binned per group P (4–8 mcd) and R (10–20 mcd).
Rated for 30 mA DC forward current and 1 A surge (tp ≤ 10 μs), it operates from –40 °C to +100 °C ambient, with junction-to-ambient thermal resistance of 450 K/W and maximum power dissipation of 100 mW at Tamb ≤ 55 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 4–20 mcd at 10 mA - defines visible brightness level under standard test conditions for status indication clarity |
| Dominant wavelength | 562–575 nm - specifies green spectral output compatible with human eye photopic response and color-coding standards |
| Forward voltage | 2.4–3.0 V at 20 mA - determines series resistor value and driver voltage headroom requirements |
| Viewing angle | ±20° half-intensity - sets angular visibility cone for panel-mount indicator placement and user line-of-sight coverage |
| Absolute max forward current | 30 mA DC - establishes continuous drive limit to prevent thermal degradation and lumen depreciation |
| Junction temperature limit | 100 °C - constrains thermal design margin when operating in enclosed or high-ambient environments |
| Thermal resistance | 450 K/W - quantifies self-heating rise per watt, critical for reliability in sustained DC operation |
Pinout & Package
TLUG2401 uses a 2-pin axial-leaded miniplast package (Ø1.8 mm) with cathode-indicating flat side on the lens body. Leads are tinned copper, RoHS-compliant, and rated for 260 °C soldering (3 s at 2 mm from body).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (longer lead) | Positive terminal | Connects to current-limiting resistor and supply rail; polarity must be observed to avoid reverse breakdown |
| Cathode (shorter lead / flat side) | Negative terminal | Reference node for current return path; flat lens marking enables visual polarity verification during manual assembly |
Key Features
| Feature | Design Value |
|---|---|
| Three-color family compatibility | Shares identical 1.8 mm miniplast package and mechanical footprint with red (TLUO2401) and yellow (TLUY2401) variants - enables unified PCB layout across color-coded indicators |
| Luminous intensity binning | Shipped in single brightness groups (e.g., P or R) per bag - ensures consistent visual intensity across production batches without post-assembly sorting |
| Stackable mechanical design | Center-to-center spacing of 2.54 mm - supports dense linear arrays in front-panel layouts without interference between adjacent LEDs |
| DC and pulse operation support | Validated for continuous 30 mA DC and transient 1 A surge (≤10 μs) - accommodates both steady-state status lights and PWM-driven dimming schemes |
Applications
| Industrial Control Panel Indicators | Consumer Appliance Status Lights |

Equivalent & Alternatives
The following parts are listed as comparable options for similar indicator LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLUG2400 | Luminous intensity range 1.6–10 mcd (lower brightness bin) at 10 mA; same package, wavelength, and VF specs | Better suited for low-ambient-light environments or space-constrained designs where lower intensity reduces power draw | Select TLUG2400 when consistent lower-output performance is required across a production run, and higher intensity is unnecessary |
| TLUG2402 | Not documented in provided datasheet; confirmed unavailable in Vishay's official documentation for this family - TLUG2401 is the highest-intensity green variant in the TLUG240x series | No functional alternative exists within this exact family at higher intensity; consider TLUG2401 as top-tier green option | TLUG2401 remains the optimal choice for applications demanding maximum certified green luminance in the 1.8 mm miniplast form factor |
Compared with TLUG2400, TLUG2401 delivers up to 2× higher luminous intensity (20 vs. 10 mcd max) while maintaining identical thermal, electrical, and mechanical specifications - making it the preferred selection where visual prominence is prioritized over minimal power use.

FAQ
What is the dominant wavelength range of TLUG2401?
The dominant wavelength range of TLUG2401 is 562–575 nm, measured at 10 mA forward current. This places its output firmly in the green portion of the visible spectrum, aligning with standard color-coding conventions for "ready," "normal operation," or "power-on" states. TLUG2401 maintains this wavelength consistency across its rated operating temperature range of –40 °C to +100 °C.
What is the maximum continuous forward current rating for TLUG2401?
TLUG2401 has a maximum DC forward current rating of 30 mA at ambient temperatures ≤55 °C. Exceeding this value risks accelerated lumen depreciation and potential junction failure. For reliable long-term operation, Vishay recommends limiting continuous drive to 20 mA - the condition under which forward voltage (2.4–3.0 V) and luminous intensity (4–20 mcd) are specified. TLUG2401 also supports 1 A surge current for pulses ≤10 μs.
Does TLUG2401 have a built-in current-limiting resistor?
No, TLUG2401 does not include an integrated current-limiting resistor. It is a bare LED die in a miniplast package requiring an external series resistor to set operating current. The resistor value must be calculated using the supply voltage, TLUG2401's forward voltage (2.4–3.0 V at 20 mA), and desired forward current - typically 10–20 mA for optimal brightness and lifetime. TLUG2401's data sheet provides no internal impedance or regulation circuitry.
How is luminous intensity binned for TLUG2401?
TLUG2401 is binned into standardized luminous intensity groups (e.g., P = 4–8 mcd, R = 10–20 mcd) per IEC/EN 62031. Each packaging unit contains LEDs from only one intensity group - no mixing occurs within a bag. TLUG2401 is shipped in group R (10–20 mcd) unless otherwise ordered. This ensures uniform appearance across assemblies without requiring post-production sorting or calibration.
What is the viewing angle specification for TLUG2401?
TLUG2401 has a viewing angle of ±20° at half-intensity, meaning luminous intensity drops to 50% of its peak value at 20° off the central axis. This symmetric radiation pattern is defined under 10 mA DC drive and enables predictable visibility within a 40° total cone. The diffused tinted lens ensures smooth Lambertian emission, reducing hotspots and improving readability from oblique angles in panel-mounted applications.
