Brass Header Pins & Male Connector Pins
Brass Header Pins and Male Connector Pins
Brass header pins and male connector pins are precision-machined square or round-post contacts used in PCB headers, IDC (insulation displacement connectors), wire-to-board connectors, board-to-board connectors, and DIP (dual inline package) sockets. Manufactured from free-cutting brass CW614N and phosphor bronze, these pins comply with IEC 60603-13, DIN 41651, and MIL-DTL-83513 connector standards. Electrical Accessories India supplies brass header pins to PCB assembly manufacturers, connector OEMs, and electronics distributors worldwide. Price: US$ 11.50/kg
Product Overview
Types of PCB Header Pins
Single-row (SIL) header pins are used in single-row 2.54 mm pitch connectors (0.1″ pitch) for wire harness connections on PCBs. Double-row (DIL) header pins are used in dual-row 2.54 mm and 2.00 mm pitch headers for IDC ribbon cable connectors and compact board-to-board connections. Right-angle (90°) header pins provide horizontal wire exit direction for panel-edge connector applications. Through-hole header pins are soldered into PCB plated through-holes; SMD header pins are surface-mounted with reflowable solder tails. PCB stacking header pins (male-female combination) are used in Arduino-style stackable development boards and modular electronics systems.
Materials and Conductivity
Standard brass header pins use CW614N free-cutting brass with 26–28% IACS conductivity and machinability above 85%. Phosphor bronze C51100 offers higher spring retention force for press-fit applications. For high-frequency signal headers above 1 GHz, oxygen-free copper C10100 pins minimize signal loss. Beryllium copper C17200 is used where combined conductivity and spring force are required in ZIF (zero insertion force) header contacts.
Pitch Options and Compatibility
Brass header pins are manufactured for standard pitches: 1.00 mm, 1.27 mm (0.05″), 2.00 mm, 2.54 mm (0.1″), and 3.96 mm. Compatibility with major connector families including Molex KK, JST PH/XH/VH, Amphenol Minitek, TE Connectivity AMPMODU, and Würth WR-PHD series. Pin square cross-section (0.64 mm) or round cross-section (0.64–1.0 mm) per connector family specification.
Plating Specifications
Tin plating (3–5 µm over nickel) is standard for soldered PCB header pins and provides good solderability per IEC 60068-2-20 solderability test. Gold flash (0.05–0.1 µm) over nickel is used for low-contact-force ZIF header connectors. Selective gold plating on mating zone only (gold on contact area, tin on solder tail) optimizes cost. Bare brass header pins are available for wave-solder applications where tin plating is applied during board assembly.
Current Rating and Voltage
2.54 mm pitch brass header pins are rated at 3A per contact at 250V AC per IEC 61058-1. Fine-pitch 1.27 mm header pins are rated at 1A per contact. High-current header pins (3.96 mm pitch, large pin cross-section) are rated at 7.5A–10A per contact for power distribution headers in automotive, industrial, and energy storage applications.
Related Connector Components
Brass header pins are used in conjunction with Brass Sockets For Pins as the mating female contact, Brass Terminal Pins for crimp wire terminations, Brass Test Pins for fixture testing, Brass Pogo Pins for test fixture interfaces, Brass Plug Pins for industrial power connectors, and Brass PCB Connectors for complete board interconnection systems.

IDC and Ribbon Cable Headers
Dual-row brass header pins for IDC (insulation displacement) ribbon cable connectors use 2.54 mm and 2.00 mm pitch with square 0.64 mm pins. Compatible with standard 26-way, 34-way, 40-way, and 50-way IDC ribbon cables per DIN 41651 and IEC 60603-13 standards.
Right-Angle Headers
90° right-angle brass header pins with horizontal exit allow PCB edge connector mounting with improved panel-mount access for ribbon cables and wire harnesses. Right-angle variants maintain full current and voltage ratings of corresponding straight headers.
Custom Header Pin Configurations
Custom brass header pin strips from 2-pin to 80-pin in single and double-row formats. Custom pin height above PCB from 3 mm to 20 mm. Breakaway header strips allow user-defined pin counts. Dual-readout headers with solder tail and test-pad access are available for production test access points.
Packaging Formats
Header pins are supplied as individual loose contacts, in strip format (4–40 positions), on tape-and-reel (T&R) for SMD variants, or as pre-loaded connector housings. Bulk packaging in anti-tarnish bags; reel quantities per customer specification.

Manufacturing Process
Brass header pins are produced by precision CNC turning or automatic screw machine production of individual pin contacts from brass rod or wire. Pin blanks are cut to length, turned to exact square or round profile, and formed with solder tail or press-fit tail geometries. Pins are then loaded into plastic housings by automated pin-insertion machines or supplied as loose contacts and strip connectors. Electroplating (tin over nickel, or selective gold) is performed in controlled plating baths with continuous monitoring. Solderability is verified by dip-solder test per IEC 60068-2-20 on every production lot. Final inspection includes dimensional check, contact resistance, insertion/withdrawal force, and solderability testing.
