PC/104 Stackthrough Connector for Embedded Bus Stacking
The 10153302-32111LF: It is the press-fit variant of the PC/104 bus connector family, designed to pass signals through stacked PC/104 modules without a separate backplane. The 64-position layout matches the PC/104 bus pinout — every position is loaded, so the BOM line maps directly to the full bus width. Rated 2A per contact at 12V. Gold flash contacts suit limited mating cycles. The press-fit termination eliminates solder — the compliant pin compresses into the plated through-hole, creating a gas-tight joint. This suits backplane-style assembly where rework or module replacement is expected.
Press-Fit Assembly and Board Stacking
The press-fit tail is the defining termination feature — no solder wicking, no reflow profile, no flux residue. The compliant pin requires a specific PCB hole diameter and plated-through-hole tolerance; the manufacturer's application note specifies the recommended hole size for the 0.100" pitch footprint. The stackthrough design means the connector passes signals from one board to the next through the pin body, so the mated stack height is determined by the board thickness plus the connector body height. The DIP=12.2 in the description refers to the pin length below the housing — 12.2 mm — which sets the clearance between stacked boards. The connector mates with the matching PC/104 receptacle on the adjacent board. No separate locking mechanism is listed; the press-fit interference holds the connector in the board, and the stack is typically secured by standoffs or a card cage. For vibration-prone installations, confirm the board-level retention — the press-fit alone may not resist shear without additional mechanical support.
It is ROHS3 compliant.
