Product Overview
XL-257UBC-L is a XINGLIGHT blue through-hole LED with a 5.0 x 2.0 x 7.0 x 28 mm package outline. The device uses a white/water colloid body and is listed as an environmental protection product meeting ROHS requirements. Its moisture sensitivity level is MSL 2, and standard packaging is in moisture-proof, anti-electrostatic foil bags.
At IF=20 mA and Ta=25°C, the LED provides 100-400 mcd luminous intensity, 455-470 nm dominant wavelength, 465 nm typical peak wavelength, and 2.8-3.4 V forward voltage with 3.0 V typical. The viewing angle is 110° typical, with 30 nm typical spectral width and reverse current of no more than 10 μA at VR=5 V.
Assembly limits include 240°C for no more than 6 s for reflow or wave soldering, and 300°C for 3 s for manual welding, with the solder point at least 2.0 mm from the colloid bottom. Storage guidance specifies temperature no more than 30°C and relative humidity no more than 70%.

Procurement Notes
When requesting a quote for XL-257UBC-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.
