The 5-103904-6 is a latching header with hold-down feature designed for the AMPMODU 2.54 mm interconnect system. This component is part of TE Connectivity's board-to-board interconnect solutions and features a 0.100 inch (2.54 mm) centerline spacing. The header is available in multiple position configurations ranging from 1 to 23 positions, with dimensions varying accordingly to accommodate different pin counts. It offers three plating options (Plating A, B, and C) to meet various environmental and performance requirements. The latching mechanism with hold-down provides secure mating and retention, making it suitable for applications requiring reliable board-to-board connections in industrial and commercial equipment where vibration resistance and positive locking are essential.
