Product Overview
XL-234UBC-L is a XINGLIGHT blue through-hole LED with a long-lead 3.0 x 2.0 x 4.0 x 28 mm appearance dimension. The device uses a white/water colloid construction and is specified as an environmental protection product meeting RoHS requirements. It is rated MSL 2 for moisture sensitivity.
At IF=20 mA and Ta=25°C, the LED is specified for 100-400 mcd luminous intensity, with a typical value of 200 mcd. Its dominant wavelength is 455-465 nm, typical peak wavelength is 465 nm, and typical spectral width at half height is 20 nm. The typical viewing angle is 110° under the stated test condition.
Electrical and thermal limits include 70 mW power dissipation, 20 mA maximum continuous forward current, 80 mA peak forward current, -20°C to +85°C operation, and -40°C to +85°C storage. Assembly guidance includes 240°C reflow soldering for no more than 6 s or 300°C manual welding for 3 s, with the soldering point at least 2.0 mm from the colloid bottom.

Procurement Notes
When requesting a quote for XL-234UBC-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.
