Product details

The 95278-802-20: The breakaway feature means the 20-position strip is a standard length; you can snap shorter sections off for a custom position count, but this part ships as a full 20-position header. The post finish is tin-lead, so the solder joint on the SMT pad is compatible with standard leaded reflow profiles. Unshrouded means there is no polarisation key or latch — the mating connector (typically a BergStik socket or IDC receptacle) relies on the board layout and housing alignment to stay oriented.

Sourcing Reality – Obsolete Part

Amphenol ICC (FCI) lists this part as obsolete — no longer in active factory production. For a BOM line that needs this exact footprint and plating, the 95278 base number is the family identifier. A functionally similar active BergStik header would require checking the current product line for a 20-position, 2-row, 0.100" pitch, unshrouded, SMT header with gold plating — but the pinout and stack height may differ. No direct drop-in replacement is documented.

The contact mating length is 0.315" (8.00mm), giving a reasonable wipe distance for a reliable connection.

Frequently asked questions

How can I order 95278-802-20 or check availability?

This part is obsolete and not in factory production. Submit a quote request with your target quantity, and we will check the surplus market for you.

What is the pinout of 95278-802-20?

The header has 20 positions in 2 rows, all positions loaded. Pin 1 is typically marked by a square pad on the PCB footprint or a chamfer on the housing. The row spacing is 0.100" (2.54mm), same as the pitch within each row.

What is the compatible socket for 95278-802-20?

Confirm the mating contact finish (gold vs tin) matches your cycle life and environment requirements.
