The HDP20 series (Heavy-Duty Power, 20-series contacts) provides IP67 sealing, high current capacity per contact, and robust mechanical construction for the demanding environments of commercial vehicles and agricultural equipment. The 31-pin configuration supports complex multi-circuit harness connections in a single connector.\u003c\/p\u003e\n\n\u003ch3\u003eKey Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e HDP26-24-31PE-L017\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e Deutsch \/ TE Connectivity HDP20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Count:\u003c\/strong\u003e 31 pins\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Size:\u003c\/strong\u003e Size 20 (7.5A per contact)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIP Rating:\u003c\/strong\u003e IP67\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Range:\u003c\/strong\u003e 20–24AWG (0.5–0.35mm²)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Temperature:\u003c\/strong\u003e -55°C to +125°C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHousing Material:\u003c\/strong\u003e Glass-filled nylon (PA66-GF), UL94 V-0\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHDP20 Series — Application Context\u003c\/h3\u003e\n\u003cp\u003eThe Deutsch HDP20 series is the high pin count extension of the DT\/DTM connector family, designed for applications requiring 20–56 circuits in a single sealed connector.

These are different from DT series size 16 contacts — do not mix contact sizes between series. The HDP20 size 20 contacts require the Deutsch HDT-48-00 crimp tool with size 20 dies (different from the size 16 dies used for DT series contacts).\u003c\/p\u003e\n\n\u003ch4\u003eHow do I identify the correct replacement connector for my vehicle?\u003c\/h4\u003e\n\u003cp\u003eThe part number HDP26-24-31PE-L017 is stamped or molded into the connector housing. Cross-reference this number with the vehicle’s wiring diagram or parts catalog to verify it is the correct replacement. For agricultural equipment, the connector location is typically documented in the implement’s electrical schematic. Contact the equipment manufacturer’s parts department if the part number is not visible on the connector.\u003c\/p\u003e\n\n\u003ch4\u003eCan I repair individual terminals in an HDP20 connector?\u003c\/h4\u003e\n\u003cp\u003eYes. Individual size 20 contacts can be extracted using a Deutsch extraction tool and replaced without replacing the entire connector housing. This is the preferred repair method when only 1–3 terminals are damaged — replacing the entire 31-pin connector and re-terminating all 31 wires is significantly more labor-intensive than replacing individual terminals.\u003c\/p\u003e\n\n\u003ch3\u003eTypical Applications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCommercial trucks:\u003c\/strong\u003e Cab-to-chassis main harness connections\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAgricultural equipment:\u003c\/strong\u003e Tractor-to-implement and ECM harness connections\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConstruction equipment:\u003c\/strong\u003e Multi-circuit control harness connections\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustrial vehicles:\u003c\/strong\u003e Forklift and material handling equipment harness connections\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003ePackage Contents\u003c\/h3\u003e\n\u003cp\u003e1 piece — HDP26-24-31PE-L017 31-pin automotive waterproof connector (housing only or complete set as specified).
