68-Position SAS/PCIe Receptacle for High-Density Storage Backplanes
The Amphenol PSAS5F3130021TR is a 68-position SAS/PCIe receptacle for internal high-speed serial interconnects in server, storage, and network equipment.
SMT Assembly Features That Save Rework
The board guide is especially useful when the footprint sits near a board edge or in a dense array of connectors — it prevents tombstoning and skewed placement that would cause opens on the 68 SMT tails. The solder retention features also help the connector survive the shear force from a cable bundle tugging on the mated plug during system integration.
Comparing the PSAS5F3130021TR to Its Siblings
The PSAS5F3130021TR shares the same 68-position count, SMT termination, gold plating thickness, and feature set as the PSAS5F3130081TR and PSAS5F3130031TR. The difference is packaging: the 0021TR ships in Tape & Reel and Cut Tape, while the 0081TR also adds Digi-Reel® availability. For a volume production line that feeds a single reel to the pick-and-place machine, the 0021TR is the standard choice — the 0081TR only matters if your procurement system requires Digi-Reel® for prototype or low-volume builds. The PSASF3130411TR is a different base product number (PSASF vs PSAS5) and should be verified against the footprint and mating interface before substituting.
