Key Features
- 50-position 2.54 mm pitch wire-to-board header plug for high-density cable-to-PCB interconnect applications
- Low-profile polarized housing prevents mis-mating and reduces vertical clearance requirements in compact enclosures
- Tin (Sn) contact finish ensures reliable mating and solderability in standard wire harness assembly processes
- 3.26 inch body length accommodates 50 contacts in a single-row plug suitable for backplane and peripheral cable connections
- TE Connectivity design heritage ensures dimensional interchangeability with standard 2.54 mm pitch PCB headers
Applications
The TE Connectivity 1-5499786-0 wire-to-board header plug is used in computer peripheral cables, industrial wiring harnesses, and embedded system ribbon cable assemblies where a 50-position 2.54 mm pitch plug is needed. Its polarized low-profile housing makes it suitable for panel wiring in CNC controllers, PLC expansion modules, and test-fixture cable assemblies where positive keying prevents incorrect insertion. The 50-position density also supports parallel data bus connections in legacy computing interfaces and industrial data acquisition systems.

Frequently Asked Questions
How many positions and what contact pitch does the TE Connectivity 1-5499786-0 header plug use?
The 1-5499786-0 is a 50-position wire-to-board header plug with a 2.54 mm (0.100 inch) contact pitch. Its body length measures 3.26 inches to accommodate all 50 contacts in a single-row arrangement, making it compatible with standard IDC ribbon cables and 2.54 mm pitch PCB headers used in industrial and computing equipment.
Does the polarization feature of 1-5499786-0 prevent incorrect cable insertion?
Yes, the 1-5499786-0 includes a polarized housing design that physically prevents insertion in the wrong orientation. This keying feature is critical in 50-position applications where reversing a connector could damage GPIO lines, data bus signals, or power rails in embedded systems and industrial controllers operating at 3.3 V or 5 V logic levels.
What contact finish does 1-5499786-0 use and how does that affect its mating life?
The 1-5499786-0 uses a tin (Sn) contact finish for termination. Tin-plated contacts typically support a mating cycle life of 30 or more insertion and withdrawal cycles, making them well suited for semi-permanent cable connections in service panels and test fixtures. Tin plating also maintains low contact resistance, generally below 20 mΩ per contact, in normal operating environments.
Which PCB header is the standard mating partner for the TE Connectivity 1-5499786-0 plug?
The 1-5499786-0 plug mates with standard 50-position 2.54 mm pitch PCB headers, such as TE Connectivity AMPMODU or equivalent industry-standard dual-row or single-row 2.54 mm pin headers. The 2.54 mm pitch is one of the most common connector standards, ensuring broad second-source availability for the mating PCB-mounted header across multiple connector manufacturers.
