use this to adapt a MMBF5457 (or any compatible footprint SMD JFET) to through-hole. 4 different through-hole pads available for various footprint options. The pin spacing is 1.27mm, so a right angle pin header like this Harwin PN# M50-3930342 should work quite well: https://www.digikey.com/short/w3mb8p70 (also available on Mouser, but sold out at the time of this writing) but honestly, I’d just bend clipped wire leads.
