Introduction
SATA 22-pin right-angle SMT receptacle designing HDD/SSD backplanes, single-board computers, DVR/NVRs, or compact storage adapters, a reliable SATA 22-pin right-angle SMT board connector is non-negotiable. Dragon Well’s DW-SAT-S22575-XXXX-01 is a right-angle, top-mount SMT receptacle that integrates the 7 signal + 15 power rows on a 1.27 mm pitch, balancing mechanical robustness with reflow-friendly solderability. With gold-plated mating contacts, matte-tin solder tails, and a proven 500-cycle durability rating, it delivers consistent performance from development to mass production.
Also called: right-angle SMT SATA connector, SATA board connector, 1.27 mm SATA connector, gold-plated SATA receptacle, SATA 7+15 connector.

Mechanical & Layout Highlights
- Overall body length: ≈ 42.25 mm (outline on PCB: 50.00 mm)
- Recommended pad span (row-to-row): 39.50 mm (overall footprint length 43.30 mm)
- Pad width (typ.): 0.80 mm; pitch: 1.27 mm (signal & power groups)
- Standoff: 1.23 ± 0.05 mm for paste thickness control and cleaning gap
- Side depth: 9.45 mm; locating/anchor holes: Ø1.40 mm and Ø1.00 mm
- Orientation: Right-angle, top-mount SMT with segregated signal/power rows
- Durability: ≥ 500 cycles; mating ≤ 45 N, unmating ≥ 10 N
Assembly Tip: Follow the pad and keep-out dimensions from the “RECOMMENDED P.C.B LAYOUT”; respect T = ±0.05 mm tolerance to maintain coplanarity and tail wetting.
The recommended footprint keeps coplanarity tight for the SATA 22-pin right-angle SMT receptacle.

- 06: 6 µin Au
- 15: 15 µin Au
- 30: 30 µin Au
Packing code: TR = Tape-Reel, TB = Tube, TP = Tray
Example: DW-SAT-S22575-30TP-01 → 30 µin Au on contacts, Tray packing.
Why DW-SAT-S22575 for Your Storage Board?
- Solder reliability: Nickel underplate plus matte-tin tails improve wetting and long-term joint stability in standard lead-free reflow.
- Connector life: ≥500 cycles suits service swaps and repeated lab use without unexpected resistance growth.
- Manufacturing yield: Standoff and pegs simplify paste control, placement accuracy, and AOI.
- Peace of mind: Materials and finishes align with mainstream SATA receptacle expectations, while Dragon Well’s vertically-integrated plants support NPI-to-mass with consistent quality.
Design teams standardize on this SATA 22-pin right-angle SMT receptacle for repeatable storage performance.
Recommended Reflow & Handling
- Follow your paste supplier’s Pb-free profile; keep peak below housing rating for LCP UL 94V-0.
- Use board supports under the connector during placement to prevent warp.
- After reflow, allow full cool-down before functional test to protect gold mating integrity.
