The designation decodes as: HD201S = connector series; 0.7 = 0.7mm contact pitch; 10 = 10-position (note: “20-pin” may refer to a 2-row × 10-position configuration). Wire-to-board connectors provide the interface between the wiring harness and the PCB inside the ECU or control module — the PCB-mount header is soldered to the ECU board; the cable-mount plug connects the harness to the header. Used in automotive ECU, BCM, TCM, and other control module applications.\u003c\/p\u003e\n\n\u003ch3\u003eKey Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e HD201S-0.7-10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Count:\u003c\/strong\u003e 20 pins (2 rows × 10 positions)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Pitch:\u003c\/strong\u003e 0.7mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnector Type:\u003c\/strong\u003e Wire-to-board (WTB) — cable-mount plug + PCB-mount header\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Range:\u003c\/strong\u003e 0.13–0.35mm² (26–22AWG)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCurrent Rating:\u003c\/strong\u003e 3–5A per contact\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e ECU, BCM, TCM, and automotive control module PCB connections\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWire-to-Board Connectors in Automotive ECUs\u003c\/h3\u003e\n\u003cp\u003eModern automotive ECUs use wire-to-board connectors to interface the external wiring harness with the internal PCB.

If individual contacts are damaged: use a micro extraction tool to remove the damaged contact, crimp a new 0.7mm contact onto the wire, and reinsert. If the PCB-mount header on the ECU board is damaged: this requires PCB-level repair (resoldering the header) — beyond standard harness repair scope.\u003c\/p\u003e\n\n\u003ch4\u003eWhat crimp tool is required for 0.7mm WTB contacts?\u003c\/h4\u003e\n\u003cp\u003e0.7mm wire-to-board contacts require a precision micro-crimp tool with dies specifically designed for the 0.7mm contact geometry. Standard automotive crimp tools will crush 0.7mm contacts. Use a dedicated micro-crimp tool for consistent, reliable crimps at this contact size.\u003c\/p\u003e\n\n\u003ch4\u003eCan I use HD201S-0.7-10 for non-automotive applications?\u003c\/h4\u003e\n\u003cp\u003eYes. 0.7mm pitch wire-to-board connectors are used in industrial electronics, medical devices, and consumer electronics where compact, reliable wire-to-board connections are required. The automotive-grade housing material (PA66, flame retardant) provides additional durability compared to standard commercial-grade WTB connectors.\u003c\/p\u003e\n\n\u003ch3\u003eTypical Applications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eECU repair:\u003c\/strong\u003e Replacing damaged cable-mount plug housings on ECU harness connections\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBCM\/TCM repair:\u003c\/strong\u003e Control module harness connector replacement\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAutomotive electronics:\u003c\/strong\u003e Wire-to-board connections in automotive control modules\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustrial electronics:\u003c\/strong\u003e Compact wire-to-board connections in industrial control equipment\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003ePackage Contents\u003c\/h3\u003e\n\u003cp\u003e1 piece — HD201S-0.7-10 20-pin automotive ECU cable-mount plug connector.
