Product Overview
XINGLIGHT XL-257UWC-L is a white through-hole LED with a 5.0 x 2.0 x 7.0 x 28 mm appearance dimension and long leads for through-hole assembly. The lens is identified as white / water colloid, and the outline dimensions are specified in millimeters with ±0.50 mm tolerance unless otherwise mentioned.
At IF=20 mA and Ta=25°C, the LED is rated for 1500-2500 mcd luminous intensity with 2000 mcd typical output. Color data includes 10000 K typical color temperature and CIE 1931 coordinates of x=0.275 and y=0.273 typical. Electrical parameters include 2.8-3.4 V forward voltage, 3.0 V typical forward voltage, and reverse current no greater than 10 µA at VR=5 V.
Assembly data includes wave soldering at 240°C for no more than 6 seconds and manual welding at 300°C for 3 seconds, with the soldering point more than 2.0 mm from the colloid bottom. Typical uses include white indication, panel status displays, and through-hole LED assemblies.

Procurement Notes
When requesting a quote for XL-257UWC-L, 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.
