Product Overview and Core Functions
This is a 2.54mm pitch dual-row DIP (Dual In-line Package) female connector, a basic type of board-to-board connector.
Core Functions:
- Matchable Connection:** Matches with female connectors of the same specification, enabling electrical connections between two PCBs or between boards and wires, facilitating modular design, testing, and maintenance.
- DIP Mounting:** Leads pass through through-holes in the PCB and are wave-soldered, providing strong mechanical strength and superior vibration resistance compared to SMT (Surface Mount Technology).
- Standardized Interface:** The 2.54mm pitch is one of the oldest and most widely used standards in the electronics industry, offering excellent compatibility.
Materials and Structure In-Depth Analysis
Contact Material:
- Base Material: Copper alloy. The industry standard is phosphor bronze, which combines good conductivity, elasticity, and fatigue resistance, ensuring stable contact force even after multiple mating and unmating cycles.
- electroplating:The product offers a standard gold plating, a common choice for high-end female connectors. Gold is chemically stable, effectively preventing oxidation and reducing contact resistance. Gold plating is typically thin (approximately 0.8-3μ"), suitable for general environments. For applications requiring higher insertion/removal life or corrosion resistance, thicker gold plating or tin plating can be selected.
Housing Material:
- Base Material: High-temperature thermoplastic. Specifically for 2.54mm DIP products, PBT (polybutylene terephthalate) or PA6T/PA9T (nylon) are commonly used.
- Key Characteristics: Flame retardant rating UL94 V-0; heat distortion temperature must be able to withstand brief wave soldering or reflow soldering at 260°C without blistering or deformation. High-temperature nylons such as PA6T/PA9T perform better than ordinary PBT.
Structure and Design:
- Dual-row design: Provides more pins within the standard width, increasing wiring density.
- DIP Pins: Square or cylindrical pins, robust and durable, suitable for manual or automated wave soldering, providing high bonding strength to the PCB after soldering, and excellent vibration and tensile strength.
- Plastic Height and Positioning: Standard products have a fixed plastic height (e.g., 8.5mm), with the Y-shaped opening facing upwards for easy pin header insertion. Some products have positioning posts on the bottom to assist installation and prevent misalignment.

In early automotive electronic control units, 2.54mm pitch pin headers and sockets were a very common board-to-board connection solution, with the following typical applications:
| Application Device | Connection Method | Description |
| Body Control Module (BCM) | Main Board ↔ Adapter Board/Control Board | Vertical stacking connection achieved via pin headers and sockets, saving PCB horizontal space |
| Audio Head Unit | Main Board ↔ Panel Button Board | Connects the audio main board to the front control panel button/display module |
| Automotive Instrument Panel | Main Control Board ↔ Display Control Board | Connects the instrument panel main control circuit to the LCD/LED display driver board. |

FAQ
Q: What is the standard product spacing?
A: Standard 2.54mm (0.1 inch), industry-standard spacing, fully compatible with 2.54mm single/double row pin headers, DuPont wires, and module pins.
Q: What are the common pin specifications?
A: Standard double row specifications: 2×2P / 2×4P / 2×5P / 2×8P / 2×10P / 2×16P / 2×20P / 2×40P, custom pin counts are supported.
Q: What are the differences in the end spring contact structure?
A: : Two main types: 1.Y-type spring contact (your model): Double-sided clamping, strong grip, vibration resistant, anti-loosening; 2.Ordinary U-type spring contact: Standard contact, lower cost, suitable for static, ordinary scenarios.
Q: What are the advantages of the Y-type structure compared to the ordinary female connector?
A: Double-sided clamping contact, stronger grip, vibration resistant, anti-loosening, less prone to disconnection in automotive/industrial control equipment.
