Why This 16-Pin DIP Socket Is Worth the Hunt
The 816-AG11D-ESL-LF: The gold flash on both the mating contact and the post provides a corrosion barrier for low-cycle signal applications — think test fixtures, programming headers, or legacy board repairs where the socket sees fewer than 50 insertion cycles over its life. For higher-durability requirements, a thicker gold plating (15 µinch or more) would be the better call.
No official successor part number is published, which means any replacement must be evaluated on form, fit, and function — pitch, position count, row spacing, and mounting style are the non-negotiable dimensions.
Footprint and Mating Half — What to Match
Contact resistance is rated at 10 mOhm, typical for a gold-flash interface in a clean environment. The beryllium copper mating contact provides good spring properties for consistent normal force over the socket's service life.
Temperature and Process Compatibility
The PCT housing material is rated for higher continuous use than standard polyester, making it suitable for applications where the socket sees elevated ambient temperatures near the board. Termination is solder — through-hole only, no press-fit option. The gold flash on the post is compatible with both leaded and lead-free solder processes, though the flash thickness means the post is not intended for repeated rework cycles.
