Key Features
- 16-position dual-row straight through-hole header at 2.54 mm pitch providing standard compatibility with a wide range of mating connectors and IDC cables
- Polarized housing design prevents incorrect mating, reducing wiring errors in production and field installations
- Tin-over-nickel barrier termination finish ensures reliable solderability and long-term corrosion resistance in PCB through-hole assembly
- Robust 1.56 inch body length accommodates large contact areas for mechanically secure board-level connections in industrial environments
Applications
The HIF3BA-16PA-2.54DSA(71) is widely used for PCB-to-cable and board-to-board signal connections in industrial control panels, laboratory instruments, and consumer electronics prototyping platforms where reliable 16-circuit connectivity at 2.54 mm pitch is needed. Its polarized through-hole design is well suited for flat ribbon cable interfaces in embedded systems, data acquisition boards, and programmable logic controller (PLC) backplane interconnects. The standard pitch and straight orientation make it compatible with common IDC socket assemblies for internal wiring in server chassis and industrial automation equipment.

Frequently Asked Questions
What is the pitch and number of pins in the HIF3BA-16PA-2.54DSA(71), and how are they arranged?
The HIF3BA-16PA-2.54DSA(71) has 16 pins arranged in 2 rows of 8 positions each, with a standard 2.54 mm (0.100 inch) pitch. The body is 1.56 inches long and 0.354 inches wide, making it compatible with standard 16-pin IDC flat cable connectors and dual-row PCB sockets commonly used in embedded systems.
Does the polarization feature of the HIF3BA-16PA-2.54DSA(71) prevent reverse insertion in production environments?
Yes, the HIF3BA-16PA-2.54DSA(71) includes a polarizing key that physically prevents reverse mating, an essential feature in industrial and laboratory environments where incorrect connector orientation on a 16-pin, 2.54 mm pitch header can damage sensitive electronics. This mechanical keying ensures correct polarity is maintained across all 16 circuits during both initial assembly and field replacement.
What contact termination finish does the HIF3BA-16PA-2.54DSA(71) use and what soldering method is compatible?
The HIF3BA-16PA-2.54DSA(71) uses a tin (Sn) finish with a nickel (Ni) barrier on through-hole pins, which is compatible with standard wave soldering and selective soldering processes at temperatures up to 260°C. The nickel barrier prevents tin diffusion into the copper contact base, extending solder joint life in applications subject to repeated thermal cycling between -40°C and +105°C.
Which Hirose mating connectors are designed for the HIF3BA-16PA-2.54DSA(71) at 2.54 mm pitch?
The HIF3BA-16PA-2.54DSA(71) mates with Hirose HIF3 series sockets and standard IDC connectors at 2.54 mm pitch with 16-way dual-row configurations. Compatible mating connectors typically support current ratings of 1 A per contact and are available in straight or angled configurations, providing design flexibility for flat ribbon cable routing in systems requiring 16-circuit interconnects.
