Product Specification

2.0mm Pitch Female Pin Header SMT 2*9pin Double Rows Pin Header Connector

Highlight

• 2.0mm pitch, dual‑row 2×9Pin SMT surface‑mount design, saves PCB footprint vs 2.54mm counterpart
• High‑temp PA6T housing, compatible with standard reflow soldering assembly lines
• Phosphor‑bronze contacts, optional gold‑flash plating, stable signal & low contact resistance
• Standard footprint, drop‑in replacement for mainstream industry equivalents
• RoHS & REACH compliant; tray packaging for high‑volume SMT mass production

Pin headers are stiff metallic connectors that are soldered to a circuit board and stick up to receive a connection from a female socket. While pin headers (often called PH, or headers) are male by definition, female equivalents are also quite common, and we refer to them as female headers (FH) or header connectors.

Product Features

1. Dual‑row 2×9Pin configuration, 18 total contact positions for multi‑channel signal transmission
2. SMT surface‑mount profile, fits automated reflow assembly; no PTH drilling required
3. High‑temperature UL94V‑0 PA6T insulator, resists thermal deformation during reflow process
4. Phosphor‑bronze contact terminals offer good spring performance for repeated mating cycles
5. Flexible plating options: gold flash/tin over nickel to balance cost and corrosion resistance
6. Standard PCB land pattern, easy library import for Altium, KiCad, Cadence
7. Black housing color; tray packing for high‑speed SMT pick‑and‑place production
8. Complies with RoHS and REACH for global market access

Product Advantage

1. Space‑saving layout: 2.0mm pitch reduces PCB occupied area compared to traditional 2.54mm headers, ideal for compact embedded hardware.
2. Mass‑production friendly: SMT tray‑packed design works seamlessly with pick‑and‑place machines, cutting assembly labor cost.
3. Reliable contact performance: Phosphor‑bronze terminals maintain stable spring force after repeated plug‑in, avoiding intermittent signal faults.
4. Engineering convenience: Standard footprint, ready‑to‑use PCB library, shortens hardware validation cycle.
5. Cost‑flexible plating: select tin plating for general signal applications; gold plating for high‑vibration / high‑humidity working environments.
6. Interchangeability: pin‑to‑pin compatible with mainstream market equivalent parts, supports BOM substitution without redesign.

Application

• Embedded control boards & IoT gateway modules
• Industrial sensor & data acquisition hardware
• Medical auxiliary control equipment
• Smart home controller PCBA
• LCD / display peripheral interface boards
• Test & measurement instrument internal interconnection
• Automotive interior non‑safety electronic assemblies

Customization Options

1. Confirm pitch: strictly select 2.0mm mating male header; mixing with 2.54mm pitch will cause assembly damage.
2. Mounting type: choose this SMT version if your project requires full SMT processing; select through‑hole type if manual welding is dominant.
3. Plating selection:
   • Tin‑nickel: for indoor normal‑humidity signal circuits, cost‑effective.
   • Gold flash plating: for outdoor, vibration‑intensive or high‑humidity working scenarios.
4. Thermal reminder: PCB pad design shall follow our recommended land pattern; avoid pad short‑circuit during reflow.
5. Current limit: each pin max 2A; do not use for heavy‑power supply loops beyond rated parameters.
6. Mating check: verify total 18‑pin (2×9) requirement; contact us for customization if you need other pin counts.
