The 20021511-00020T4LF: The 0.091" (2.30 mm) solder post length is short enough to keep through-hole stubs from creating impedance discontinuities in signal paths below 100 MHz, while still providing a solid solder fillet on the bottom side.
Full Shroud and Keying Slot for Harness Assembly
The 4-wall shrouding completely encloses the male pins — this prevents bent pins during blind mating and protects the contacts from accidental shorting against conductive surfaces. The keying slot in the shroud ensures the mating receptacle can only be inserted in one orientation, eliminating reverse-polarity mis-mates. Push-pull fastening means the connector pair is held together by friction and the shroud's latch features — no screws or locking clips. This is adequate for low-vibration bench equipment or test fixtures, but for automotive or machine-tool environments a secondary locking mechanism on the receptacle side is recommended.
Temperature Range and Material Compliance
Mating Half and Terminal Cross-Reference
The 20-position header requires a 20-position receptacle housing; the terminal part number is the same across all Minitek127® housings.
