Product Features

1. Dual‑row layout, 2.54 mm (0.100") pitch, 0.64×0.4 mm square contact dimension for accurate pin‑mating alignment
2. High‑temperature UL94V‑0 thermoplastic housing, resistant to reflow thermal shock
3. Phosphor‑bronze / brass contacts, customizable gold/tin plating on mating & soldering areas
4. Multiple pin‑count options: 2×2P to 2×40P; vertical / right‑angle orientation available
5. Support tape‑and‑reel SMT pick‑and‑place, tray and bulk packing modes
6. RoHS‑compliant, qualified for consumer, industrial and IoT electronic applications

Product Advantage

1. 0.64×0.4 mm square contact: Compared with common round‑hole female headers, square contact delivers larger contact area, lower contact resistance and better anti‑vibration performance for vibration‑prone equipment.
2. Dual‑compatible assembly: Supports both through‑hole manual soldering and SMT tape‑and‑reel mass production; one part series covers prototype and mass‑production phases.
3. Flexible plating solution: Engineers can select tin‑plating for cost‑sensitive projects or specified gold thickness for high‑reliability signal contacts, avoiding over‑spec cost waste.
4. Full‑range pin‑count customization: 2×2P‑2×40P covers most embedded board‑to‑board interconnection scenarios, with short lead‑time for standard parts.
5. Stable thermal performance: UL94V‑0 high‑temp housing reduces housing melting risk during reflow soldering, lowering assembly reject rate.

Application

• Industrial control mainboard & sensor modules
• IoT gateway, smart home controller hardware
• Embedded development boards, test & measurement equipment
• Medical auxiliary electronic modules
• Automotive interior auxiliary electronics
• Consumer electronics, power supply units

Customization Options

1. Confirm pitch: Must match mating male pin header pitch = 2.54 mm, contact dimension 0.64×0.4 mm square.
2. Confirm pin‑count: Count total circuit signals; dual‑row format = 2 × N positions.
3. Select mounting type:
   • SMT: choose tape‑and‑reel packaging for pick‑and‑place machine
   • Through‑hole: select bulk/tray for manual soldering
4. Orientation: Vertical for stacking‑board; Right‑angle for side‑direction board interconnection.
5. Plating selection:
   • Cost‑sensitive non‑signal pins: Tin‑plated
   • Signal path/vibration environment: Gold‑plated (confirm Au thickness requirement)
6. Operating environment: If working under continuous >85 ℃, select PA6T housing version.
