Product details

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.

Frequently asked questions

What is the mating finish on 54101-G0502LF?

30 µinch gold or Gold, GXT™ on the mating face, with 100 µinch tin on the solder tails.

What is the closest alternative to 54101-G0502LF?

The 54101-T0802LF is the same header with a tin mating finish instead of gold — adequate for low-cycle, low-vibration applications.
