The 78229-205HLF is the 5-position single-row member of the BergStik II header line.
Through-hole mounting with a press-fit compliant tail that also accepts solder for additional mechanical retention.
The housing material carries a UL 94 V-0 flammability rating. RoHS and REACH compliance documentation is available from the manufacturer for this part number.
A pin-compatible alternative would be any other 5-position single-row 0.100" pitch unshrouded header from the same series, such as the 78229-105HLF (tin-plated) or 78229-305HLF (higher gold thickness) — confirm the contact finish and thickness against the application requirement.
