Replacing Hakko FX-888D connector

The pins on the panel mount connector lose their springy-ness over time causing an intermittent connection

Iron wasn't heating up solder joints fast enough.

Wiggling the cable near the connection at the base unit would give intermittent "S-E" error.

Read other posts that this was a common failure.

I've had my Hakko FX-888D for over 10 years at this point.


  1. Get a new one ($130)
    1. Pros - Well-Made, small footprint, affordable, already have a bunch of spare tips.
    2. Cons - Will it fail in 10 years?, Buying the whole machine for one small failure seems wasteful.
  2. Upgrade to a fancier machine ($300+)
    1. Pros - Options include tweezers and micro-soldering capabilities
    2. Cons - Money, Space requirements for more bells and/or whistles
  3. Replace the connector with a more  robust option ($20)
    1. Pros - Cheap, Learning process
    2. Cons - If it fails, I'll have no soldering station, will need to choose between 1 & 2 above, and have wasted time.

Option 3 it is. Let's go.
