Board Fit and Contact Plating
The 54101-G0502LF: Through-hole termination gives the header stronger mechanical retention than an SMT version when the cable assembly sees strain.
RoHS compliant per the lifecycle record.
Peer Comparison: Gold vs Tin Mating Finish
The 54101-T0802LF is the same 2-position, 2.54mm pitch, unshrouded header but with 100 µinch tin on the mating face instead of 30 µinch gold. Gold buys higher mating cycle life and better corrosion resistance; tin is adequate for low-cycle, low-vibration applications.
