SELECTION GUIDE

CFast, CF & CFexpress Connector (Socket) Selection Guide

Industrial imaging storage spans 3 interface generations — CompactFlash, CFast and CFexpress / XQD — and the socket follows the card the host controller supports, not the card body. KINGCONN carries all 3: CF at 50 positions in 0.635mm and 1.27mm pitch rated to 10,000 cycles, CFast at 1.27mm pitch and 8.35mm profile, and CFexpress / XQD with LCP housings and SUS304 stainless shells.

CF: the workhorse of installed equipment

CF sockets in the catalog are 50-position with 0.635mm and 1.27mm pitch versions and durability up to 10,000 cycles. CF is still everywhere in shipped industrial machines; if your original socket source has gone end-of-life, send the drawing or part number and KINGCONN evaluates supply from existing tooling.

CFast and CFexpress

Catalog CFast models are 1.27mm pitch at 8.35mm profile, also in the 10,000 cycle class, available as push-push, non-push and lock mechanisms. CFexpress / XQD models use glass-filled LCP housings with stainless (SUS304) shells for the mating precision the format requires.

KINGCONN CF, CFast and CFexpress sockets

CF card headers, CFast host connectors in push-push, non-push and lock versions, and CFexpress Type A / XQD.

Materials, compliance and RFQ

Across the families: LCP housings rated UL94V-0, phosphor bronze contacts, stainless shells on some models. RoHS compliant, and every published value carries its source drawing number. Browse CF, CFAST and CF express & XQD, or send your card generation and eject mechanism requirement to service@kingconn.com.tw.

FAQ

What is the difference between CF, CFast and CFexpress?
Similar card bodies, completely different interfaces: CF is parallel ATA (50 positions); CFast keeps the CF body but runs SATA; CFexpress / XQD runs PCIe / NVMe. The sockets are not interchangeable — follow the card the host controller supports.
Are CF sockets still in production?
Yes. CF is still everywhere in installed industrial equipment. The KINGCONN catalog lists 8 CF models at 50 positions in 0.635mm and 1.27mm pitch, rated up to 10,000 mating cycles. If your original source went end-of-life, send the drawing or part number for evaluation.
Which CFast mechanisms are available?
Push-push, non-push and lock types, at 8.35mm profile and 1.27mm pitch. Choose the lock type for equipment that must not lose the card mid-recording.
Are CFexpress Type A and Type B sockets the same?
No — different card size and contact count. The KINGCONN catalog carries CFexpress Type A (7CFEA-C0-0001); send your specification if you need Type B.
What gets overlooked when selecting for industrial machines?
The eject mechanism and shell retention. Industrial vibration and side load are far above consumer levels, so choose parts with a stainless shell, locating bosses or through-hole legs rather than comparing interface and pin count alone.
