Product Overview
XINGLIGHT XL-257UGC-L is a green through-hole LED with an appearance dimension of 5.0 x 2.0 x 7.0 x 28 mm. The datasheet identifies the colloid/lens color as white/water colloid and states that the device meets RoHS requirements with moisture sensitivity level MSL 2.
Electrical and optical ratings are specified at IF=20 mA and Ta=25°C for the main characteristics. Luminous intensity is 900 mcd minimum, 1500 mcd typical, and 1800 mcd maximum. Dominant wavelength is 515 to 530 nm, peak wavelength is 525 nm typical, forward voltage is 2.8 to 3.4 V, viewing angle is 110° typical, and spectral width at half height is 30 nm typical.
Assembly limits include wave soldering at 240°C for up to 6 seconds and manual welding at 300°C for 3 seconds, with the soldering point more than 2.0 mm from the colloid bottom. The device is packaged in moisture-proof and anti-electrostatic foil bags and is intended for applications needing green visual indication in through-hole assemblies.

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