Product Overview
XL-4014UYC-02 is a XINGLIGHT yellow SMD LED supplied in a 4014 surface-mount package with outline dimensions of 4.0 x 1.4 x 0.8 mm and a general outline tolerance of ±0.25 mm unless otherwise noted. The luminous color is yellow, and the lens or colloid is specified as colorless transparent.
At IF=60 mA and Ta=25°C, the LED is specified for 400 to 800 mcd luminous intensity, 585 to 595 nm dominant wavelength, 590 nm typical peak wavelength, 1.8 to 2.4 V forward voltage, 120° typical viewing angle, and 20 nm typical half wave width. Reverse current is limited to <=5 µA at VR=5 V and Ta=25°C.
Assembly data includes MSL 3 moisture sensitivity, maximum two reflow soldering cycles, opened-package soldering within 168 hours at <=30°C and <40% RH, and baking at 60 ±5°C for 24 hours when required. These specifications support use in yellow indicator, display, panel, and compact surface-mount lighting circuits where the stated electrical, optical, moisture, and soldering limits are observed.

Procurement Notes
When requesting a quote for XL-4014UYC-02, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For LED and optoelectronic sourcing, brightness bin, wavelength or color temperature bin, forward voltage range, viewing angle, moisture sensitivity level and soldering process limits may affect final selection, availability and lead time.
