The 24Gbps SFF-8644 1×4 R/A Connector is part of the MiniSAS HD range and is supplied in stock from our factory in Dongguan. It is supplied genuine through Amphenol’s authorised distribution channel, with full batch traceability and documentation for incoming inspection.
Specifying the R A Connector
Every unit is inspected before dispatch and ships with a test report, so incoming inspection becomes a document check rather than a re-test. Material compliance is documented against RoHS and REACH.
Key features
- Genuine Amphenol product through the authorised distribution channel
- Full batch traceability with documentation for incoming inspection
- No minimum order quantity — single pieces and volume builds both supported
- Signal-integrity data available for the lane rate you intend to run
- Cage and connector available as a matched pair
- Engineering support from the manufacturer rather than a reseller interpretation

Quality assurance
Product is sourced through Amphenol's authorised channel and verified on receipt for marking quality, packaging integrity and part-number correspondence. KINKUO operates an ISO 9001:2015 certified quality management system, and documentation is available for every batch supplied.
Selecting the right MiniSAS HD
Confirm the cage and connector form a matched pair before committing to a layout. Mechanical tolerances stack between vendors, and a mismatch discovered at volume is expensive to unwind.
Review the thermal path at design stage. Higher lane rates dissipate more power in the module, and the cage is part of the heat path — a platform that passes bench testing can still throttle in a hot aisle.
Packaging and delivery
Parts are supplied with the documentation your incoming inspection needs: part-number correspondence, batch traceability and, where applicable, signal-integrity data for the lane rate in question.
Because there is no minimum order quantity, a single port can be replaced as easily as a volume build can be scheduled. That matters most during validation, when a design change may require a different variant at short notice.
Common questions
How do I know the parts are genuine?
Product is sourced through Amphenol's authorised channel and verified on receipt for marking quality, packaging integrity and part-number correspondence. Full traceability is provided with every batch.
Is there a minimum order quantity?
No. Single pieces and volume builds are both supported, which makes validation and urgent replenishment practical.
Can you supply the cage and connector together?
Yes, and we recommend it — a matched pair avoids the tolerance stacking that appears when the two are sourced separately.

Why source this part from KINKUO
We manufacture rather than resell, which means the part you receive is built on our own calibrated equipment by the same team that engineers it. That removes the margin stacking of a trading chain and keeps lead times predictable. Established in 2010, we supply minisas hd to customers across South China, East China, Japan, Europe and North America.

Every r a connector we ship is inspected against the drawing before packing. A r a connector can be supplied with a batch test report and material declarations. Where a r a connector runs in volume, call-off scheduling keeps material allocated.
