Product Specification

Dual Row 2.54mm Pitch Pin Header Connector Heightening 220pins Straight Stacking Header 0.1 Inch Pin Female Header

Highlight

• Heightened stacking body, extra vertical clearance for component‑on‑board stacking layout
• Standard 2.54 mm (0.1") pitch dual‑row 2×20P, fully compatible with mainstream 0.1‑inch male pin headers
• Through‑hole straight vertical design, strong mechanical retention for repeated plug‑unplug
• UL94‑V‑0 flame‑retardant insulator, RoHS‑compliant, supports tin / selective gold plating options
• Customizable stacking height, pin length and plating thickness for industrial & prototyping projects

Pin headers are stiff metallic connectors 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 2×20P (40 contacts), 2.54 mm / 0.1 inch standard pitch, interoperable with off‑the‑shelf 0.1” male pin headers
2. Heightened insulator housing, increased stacking clearance to avoid component collision between stacked PCBs
3. Straight vertical through‑hole construction; stable positioning during wave soldering
4. Spring‑loaded female contact sockets, consistent gripping force to prevent intermittent connection
5. Black PA6T / PBT housing, UL94‑V‑0 flame resistance, wide operating temperature range
6. Multiple plating options: pure tin, selective gold flash over nickel base for different cycle‑life requirements
7. RoHS & REACH compliant, available for OEM dimension adjustment (pin length, stacking height, pin count)

Product Advantage

1. Heightened stacking advantage: Solves interference issue when tall components are mounted on overlapping PCBs; no need to modify PCB layout. Differentiates from ordinary low‑profile female headers.
2. Interchangeability: Strict 2.54 mm pitch dimension tolerance, directly mates with generic 0.1‑inch male pin headers from major vendors.
3. Mechanical reliability: Through‑hole soldering provides far stronger pull‑out resistance than SMT headers, suitable for devices under shock & vibration.
4. Cost‑flexible plating solution: Selective gold only on contact mating area balances service life and BOM cost, instead of full‑surface expensive gold plating.
5. Engineering flexibility: Support modification on stacking height, pin tail length, and pin count for quick project adaptation.

Application

• Embedded control boards & industrial controller modules
• IoT gateway, sensor acquisition units
• Single‑board computer expansion shields, prototype development platforms
• Automation equipment, test & measurement instruments
• Consumer electronics, power supply stacking modules
• Medical auxiliary equipment, communication peripheral boards

Customization Options

1. Confirm mating part: Must match 2.54 mm pitch dual‑row male pin header; verify pin square size and mating depth.
2. Stack height planning: Measure tallest component on lower PCB, select adequate heightened housing height to prevent physical collision.
3. Mounting: This is through‑hole type; ensure PCB footprint matches through‑hole pad layout. Do not use for SMT‑only assembly lines.
4. Plating choice: Tin plating for low‑mating‑cycle static connections; selective gold for frequent plug‑in or humid industrial environment.
5. Current derating: Derate per‑pin current under high‑density multi‑signal & power mixed application.
6. Custom request: If standard 2×20 does not fit, we can cut or mold other pin‑count variants.
