PATA CompactFlash and PCIe/NVMe CFexpress are different card families; a CF reader label is incomplete.

How they differ
CompactFlash Type I card interface Read the full card label, including Type I where documented, and compare the recessed contact end with the reader specification.
CFexpress Type B card interface Read Type B on the card and the exact supported-media list; record the camera firmware requirement where one is given.

Connector role
card (TS32GCF800)S920Named source examples retain separate role, part, view and axis limits; values are not a universal family specification. TS32GCF800. Documented role: card. Actual full official2page PDF captured and hashed. Dimensions tuple is explicit, but table does not name width/length axes.; CFA legacy mechanical specifications require non-member purchase; no purchase attempted and no extra pitch/key geometry invented.

Key distinction
The word Compact does not identify a card interface.
Illustrations are computer-generated with prior AI visual review; independent technical and rights review pending. A comparison is not a compatibility verdict.
This comparison stays within one evidence layer.
All selected records are Connector records. Similar layer does not mean compatible, interchangeable or safe to mate.
Not a size comparison. Illustrations fit the same display boxes; their physical dimensions are not shown to a common scale. No mating or compatibility verdict follows.
Label-led symbol — not interface geometry. Read the exact designation and written reference; do not identify a physical connector by this generic shape.
Label cue: Read CompactFlash Type I in the written label
The strip is a placeholder, not a contact layout.
Still check: The dark bar is not a drawing of recessed contacts. Thickness and exact reader support remain unestablished by this symbol.
Label-led symbol — not interface geometry. Read the exact designation and written reference; do not identify a physical connector by this generic shape.
Label cue: Read CFexpress Type B and the exact supported-media list
The dark strip is not the card contact arrangement.
Still check: A shared form with XQD does not establish that a camera or reader supports either format.
