Product Overview
LTST-C171TBKT is listed by Lite-On as an affected Chip LED part number in Product / Process Change Notification PCN-20210076. The document describes the introduction of additional dice materials for chip LED products, with the change effective Sep. 1st 2021 and issued on Jun 1st 2021 by LITEON OPS SMD LOB.
The extracted facts do not specify a package case outline. The documented structure-level change concerns die dimensions: the original die is 229 um long, 178 um wide, and 80 um thick. Two new die options are listed: 200 x 300 x 90 um and 178 x 221 x 90 um.
Lite-On identifies the reason for change as mitigation of potential risk to supply continuity through an alternative bill of materials. The alternative dice are qualified in the Lite-On materials pool, and Lite-On states that its internal qualification process was implemented for alternative material reliability evaluation.

Procurement Notes
When requesting a quote for LTST-C171TBKT, 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.
