Product Overview
The XL-1606UOC is a XINGLIGHT high brightness orange SMD LED supplied in a 1.7 x 0.6 x 1.1 mm package. The datasheet describes a transparent/water colloid package and states RoHS compliance and MSL 3 moisture sensitivity handling requirements.
At IF=20 mA and Ta=25°C, the LED is specified for 80 to 240 mcd luminous intensity, 600 to 608 nm dominant wavelength, 605 nm typical peak wavelength, 1.8 to 2.4 V forward voltage, 20 nm typical half wave width, and 120° typical viewing angle. Absolute maximum ratings include 50 mW power dissipation, 20 mA continuous forward current, 80 mA peak forward current with pulse width <=0.1 ms and duty <=1/10, 5 V reverse voltage, and 2000 V ESD withstand voltage.
Assembly guidance includes a 260°C <=6 s lead soldering limit, a recommended maximum welding temperature of 240 ±5°C for 6 s, and no more than two reflow soldering cycles. The device is applicable to compact orange indicators, status lighting, color-coded signals, panel indicators, and small-format display points.

Procurement Notes
When requesting a quote for XL-1606UOC, 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.
