Hybrid Signal-Power Receptacle for Backplane and Power Distribution
The TE Connectivity 2-1926739-5 is a 35-position MINIPAK HDL receptacle that combines 25 signal contacts and 10 power blade sockets in a single housing — a hybrid layout that saves board space by eliminating a separate power connector. The 2.00 mm pitch packs the signal rows tightly while the power contacts handle bus-level current through dedicated blade sockets. The press-fit termination eliminates soldering, which makes the connector rework-friendly and avoids thermal stress on the PCB during assembly. Press-fit is the standard termination for high-reliability backplane connectors where solder-joint inspection is impractical.
Contact Layout and Plating — What the 25+10 Arrangement Means
The 25 signal contacts are arranged for lower-current data or control lines, while the 10 power blade sockets carry the higher-current supply rails. This split means a single connector handles both the logic wiring and the main DC bus, which simplifies the BOM and reduces the number of connector positions on the board edge. The 30.0 µin gold thickness is above the 15 µin flash typically used for low-cycle consumer connectors. This is a field-service-grade plating — the connector is designed for the mating-cycle counts expected in telecom or server racks where cards are replaced multiple times over the equipment life.
The black housing colour is typical for power-distribution connectors within an enclosure.
Comparison with 2-1437357-0
The 2-1437357-0 is the same MINIPAK HDL series but differs in two procurement-relevant ways: it is packaged in Spool (continuous reel) rather than Tray, and it carries a 28 A current rating per contact versus the unspecified current on the 2-1926739-5. For a volume build that uses automated placement, the Spool-packaged variant may be preferred. Both parts are active, so the choice depends on the assembly line's feeder setup and the current requirement per power contact.
