The 1-390262-2: The base product number 390262 covers a family of DIP headers; any pin-compatible substitute would need to match the 28-position, 0.100" pitch, 0.6" row spacing, and right-angle through-hole mounting.
Termination and Operating Range
Contact resistance is specified at 30mOhm maximum, which is typical for tin-plated phosphor bronze contacts at this pitch and current level. The open-frame construction allows airflow around the contacts, aiding thermal management in multi-row headers.
