7201JY connectors and accessories available at Communica for immediate or branch collection.
PCB connectors are essential for establishing reliable, maintainable connections between printed circuit boards and external devices or cables. The 7201JY series has become a popular choice among South African electronics hobbyists, tertiary institutions, and industrial OEMs due to its robust design, cost-effectiveness, and compatibility with standard PCB layouts. These connectors are widely used in student projects, prototyping platforms, instrumentation, and commercial equipment manufactured or serviced locally.
7201JY connectors are rectangular, pin-through-hole (PTH) style PCB-mounted headers. They are versatile for applications requiring:
Typical specs for 7201JY connectors stocked by Communica are:
| Specification | Common Value | Notes |
|---|---|---|
| Pitch (pin spacing) | 2.54 mm | Standard for breadboard/PCB compatibility |
| Pin Count | 2-40 pins/row | Single or double row available |
| Rated Current | 1-3 A (typical) | Always check datasheet for your exact model |
| Mating Style | Female header/socket or ribbon cable IDC | Flexible for prototyping and assembly |
| Termination | Solder (through-hole) | Compatible with hand and wave soldering |
| Standard Colour | Black | Easily identifies signal headers |
7201JY connectors are widely available in South Africa through distributors like Communica, supporting local projects with fast lead times and a selection of related accessories (housing, shrouds, locking variants).
Before choosing a PCB connector for your project, consider:
Students often select 7201JY connectors for microcontroller dev boards, sensor breakouts, or rapid-prototyping shields. Industrial users incorporate them in modular test jigs or field-repairable interfaces due to their robust contacts and common tooling.
Suppose you're building an embedded system with a microcontroller board and need to interface multiple daughterboards (sensors, relay modules, etc.). A 20-pin 7201JY header can route signals and power:

> Microcontroller Board
> Power Rail
If each pin is rated for 2A, and you parallel 2 pins for the 5V rail, your combined current handling is:
Total Irated = N_pins x I_pin
(N_pins = 2, I_pin = 2A) 4A available to your circuit (apply conservative derating of 20% for safety, so usable ~3.2A).
Communica supplies semiconductors and electronic components to industries such as automotive, electrical, automation, mining, and education.
