I’ll turn this into a cited application and usage guide for the Samtec TSW-104-07-G-S, verify the mechanical/electrical details from primary sources, and save the finished guide in the project.
The Samtec TSW-104-07-G-S is a 4-position, single-row, vertical through-hole male header with 2.54 mm pitch and 0.635 mm square posts. It is most commonly used as a simple board-to-board, board-to-wire, programming, test, or low-speed power/signal interface when a polarized or latched connector is not required.
1. Quick Specifications
Engineering interpretation: Do not treat 5.7 A as an unconditional rating for every installation. The published current values are tied to specific mating systems, and practical allowable current may be lower because of harness wire gauge, PCB temperature rise, connector derating, and the number of adjacent energized contacts.
Created the cited TSW-104-07-G-S Application and Usage Guide. It covers specifications, pin usage, integration, PCB layout, pitfalls, alternatives, sourcing, and clearly identifies the recommended PCB hole diameter as requiring verification from the current Samtec footprint.
