Q1: Which terminals are recommended for the 14-way 0430251400 housing?

A: This housing uses Molex 43030 series female socket contacts. Depending on your wire gauge (typically 20-30 AWG) and plating needs (Tin, Gold, or Selective Gold), we suggest selecting the terminal that best matches your header’s plating to avoid galvanic corrosion.

Q2: Does the 0430251400 mate with wire-to-wire plugs?

A: Yes, it mates with 43020-1400 series plug housings for wire-to-wire connections, and with various 43045 series headers for wire-to-board applications.
