Product Overview
XL-257SYGC-L is a XINGLIGHT yellow green through-hole LED supplied in a 5.0 x 2.0 x 7.0 x 28 mm long-lead package. The product description specifies yellow green luminous color with white / water colloid lens construction, and the package outline tolerance is ±0.50 mm unless otherwise specified.
At IF=20 mA and Ta=25°C, the device is specified for 50 to 100 mcd luminous intensity, 565 to 575 nm dominant wavelength, typical 570 nm peak wavelength, and 2.0 to 2.6 V forward voltage. The typical viewing angle is 110°, spectral width at half height is 15 nm, and reverse current is limited to 10 µA maximum at VR=5 V.
Assembly data includes wave soldering at 240°C for no more than 6 s and manual soldering at 300°C for 3 s, with the solder point at least 2.0 mm from the colloid bottom. Lead bending should also keep at least 2 mm clearance from the colloid. Typical uses include yellow green indicators, control-panel status lights, and through-hole equipment display points.

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