MINIPAK HDL Hybrid Signal/Power Backplane Connector
The TE Connectivity MINIPAK HDL 1926734-4 is a 35-position plug with male pins and blades, arranged in a 25-signal, 10-power contact layout across 5 rows. It terminates via press-fit compliant pins — no solder — and mounts at a right angle to the board edge, which puts the mating interface parallel to the PCB plane. This is the plug half of a backplane or midplane interconnect system, designed for high-density, high-reliability assemblies where the daughtercard plugs perpendicular into the backplane. Board locks and a mating guide are integrated into the housing: the board lock anchors the connector during the press-fit insertion process, and the mating guide prevents contact stubbing during blind-mate assembly.
Sourcing Reality: Obsolete, Sourced to Order
The 1926734-4 is listed as Obsolete by the manufacturer. No official replacement or cross-reference order code appears on record.
Press-Fit Termination and Board Layout Fit
Press-fit termination means the compliant pin cold-forms into the plated through-hole — no solder joint, no reflow profile, no flux residue. The 35-position count with 25 signal and 10 power contacts is the critical footprint parameter for the board layout engineer. The power contacts require wider PCB traces and larger clearance zones than the signal pins. The 5-row arrangement packs the hybrid layout into a single connector body, saving board real estate compared to separate signal and power headers.
