Pin numbering is electrical numbering, viewed according to the manufacturer package drawing. Consult the linked datasheet for absolute maximum ratings, operating conditions, unused-pin handling and assembly limits.

Reusable assets and qualification

The symbol and footprint are supplied as editable KiCad files. The footprint model path is project-relative: place package-reference.step beside the consuming project or update that path explicitly.

Generic KiCad package geometry; not manufacturer-issued exact-ordering-code CAD. Independent dimensional, terminal and native-import validation remains required.

This is a development catalog record. Pin mappings come from the manufacturer reference; native import, electrical review, seating/pin-1 overlay review, native model fidelity is not yet qualified. These downloads must not be treated as manufacturing approval.

Sources and license

Original symbol/documentation and original package drawings: MIT (LICENSE). Upstream KiCad footprint/package assets retain CC-BY-SA 4.0 with the KiCad library exception; provenance.json records source URLs and hashes. No manufacturer ownership is claimed for generated or upstream community geometry.

The annotated hero separates nonphysical pad/silkscreen labels from the clean model. The added exact MPN is a virtual identification aid, not a factory marking. Automated marking-fit and geometric-centering checks pass; neither proves package qualification. Editable Fusion library and canonical library JSON are included.

Functional symbol alternative

Grouped symbol with package outline and vector preview preserve the exact electrical pin numbers and types. The central vector artwork is derived from the documented package reference, including its virtual MPN. The default compact symbol remains available; this alternative is prepared for native import review.
