Product Overview
XL-257SURC-L is a XINGLIGHT red through-hole LED supplied as a long-lead lamp device with a 5.0 x 2.0 x 7.0 x 28 mm outline. The package description specifies a white / water colloid body, red luminous color, and an outline dimension tolerance of ±0.50 mm unless otherwise specified.
At Ta=25°C, the LED is rated for 70 mW power dissipation, 20 mA maximum continuous forward current, and 80 mA peak forward current. Electrical and optical characteristics at IF=20 mA include 1.8 to 2.4 V forward voltage, 50 to 300 mcd luminous intensity, 615 to 625 nm dominant wavelength, 625 nm typical peak wavelength, 20 nm typical spectral half-width, and 110° typical viewing angle.
Assembly data specifies wave soldering at 240°C for no more than 6 seconds and manual welding at 300°C for 3 seconds, with the solder point at least 2.0 mm from the colloid bottom. Storage guidance includes ≤30°C, ≤70% RH, and original package storage time of ≤3 months.

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