Material Composition | Industrial Automation, Aerospace | Steel pins (basic plating) ▲ Brass + tin plating ▲ Gold-plated brass (24K, 3μm) (resists corrosion) | Enhanced conductivity (gold ▲) and heat resistance (PBT plastic) | Higher cost for gold-plated variants (Industry Standard: $1.50 ▲ Base: $2.00 ▲ Advanced: $3.50) |
Pin Count & Configuration | PCB Assembly, Prototyping | 28-pin DIP (0.1" spacing) ▲ Alignment notches added ▲ Reinforced pin design (IEC 60601) | Compatibility with standard PCB layouts ▲ Easier soldering alignment ▲ Durability | Limited to 28 pins for complex circuits; requires precise PCB design for alignment |
Mounting Style | Automotive Electronics, Consumer Devices | Through-hole ▲ Surface-mount (SMD) with locking tabs ▲ Vibration-resistant locking (tested to MIL-STD-810G) | Secure attachment during soldering ▲ Resistance to mechanical stress (Advanced ▲) | Requires SMD reflow equipment for assembly (Industry Standard uses simpler through-hole) |
Electrical Performance | Power Supply Units, Industrial Control | Contact resistance >100mΩ ▲ <50mΩ ▲ <20mΩ (ISO 17353) | Reduced signal loss (Advanced ▲) ▲ Supports high-current applications (2A/pin) | Higher thermal management needed for Advanced variants under load |
Durability & Longevity | Manufacturing Test Equipment, Robotics | 500 insertion cycles ▲ 1,000 cycles ▲ 2,000 cycles (IEC 60601) | Extended service life in high-use environments (Advanced ▲) | Initial cost trade-off for longevity features |
Customization & Identification | Mass Production, Military Systems | No customization ▲ Color-coded variants ▲ CustomLabeling + UV markings (ASTM D1617) | Easier board assembly (color coding ▲) ▲ Tamper-proof UV labels (Advanced ▲) | Custom orders incur longer lead times and higher minimum quantities |
