Product Overview
XL-2520UWC-TR7 is a XINGLIGHT white through-hole LED with yellow colloid/encapsulant and a compact outline listed as 2.1 x 2.3 x 2.6 x Ø1.8 mm. The datasheet defines the outline dimension tolerance as ±0.254 mm unless otherwise specified, and identifies the moisture sensitivity level as MSL 3.
At IF=20 mA and Ta=25°C, the LED is specified for 200-500 mcd luminous intensity, 15000-25000 K color temperature, typ 80 color rendering index, and typ 20° viewing angle. Forward voltage is specified as 2.8 V minimum, 3.0 V typical, and 3.2 V maximum, while reverse current is max 5 µA at VR=5 V.
Assembly guidance includes 260°C for ≤6 s lead soldering, hand soldering below 300°C for less than 3 s per terminal, and up to two Pb-free reflow cycles with a recommended maximum of 240 ±5°C for 6 s. Storage guidance calls for use within one year unopened at ≤30°C and <60% RH, then soldering within 168 hours after opening at ≤30°C and <40% RH.

Procurement Notes
When requesting a quote for XL-2520UWC-TR7, 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.
