I think it's a bit ironic that the cable is considered more costly than the receptacle, which is generally true if you consider the device as a whole, but now we have multiple hundreds of dollars thunderbolt cables and the cap on the actual receptacle component is below $10 even for ones with support for higher speeds.

But then again, most people don't have the SMD rework tooling to be able to easily replace receptacles

This is mostly an exaggeration.

Apple has a $160 3m 40Gbps cable but Cable Matters has the same for $70 (and Trebleet has a 2.5m one for $50).

The 25 feet 40gbps cable from Pure Fi is the only I can think of that fits the "multiple hundreds' description at $200 but then again it's an active optical cable (it's not compatible with plain USB).

Maybe the actual C connector they started with is below $10 but you are looking at rather expensive redriver chips inside and careful engineering to care for the signal integrity at 40gbps.

It is rather less than 1 usd even on Lcsc where everyone can buy it

Yep, that's really what I was getting at. They're generally attached to the motherboard (rather than a separate PCB) and most people don't have a rework station and the iFixit tools. And the patience.

The receptacle shouldn't be more than $1-2 on DigiKey last I checked. [1]

It is probably easier to have two cables and replace a broken one in case of failure than replacing your USB connector (or the lifted pads) in case of failure.

A broken cable means the cable will be replaced, a broken connector might mean the device is thrown out.

Now I am a person with the skill and tools to replace such a connector or patch up the PCB in most cases, but Ibstill think I'd rsther replace the cable. Thebexpensive thing isn't the part. It is my time.

Paying multiple hundreds of dollars is a choice, not a necessity. An active 40 Gbps, 240W cable is around $50 these days. I doubt that most repair shops would even give you a repair estimate for less than that.

> But then again, most people don't have the SMD rework tooling to be able to easily replace receptacles

And that's exactly why a reasonable design assumes that buying a new cable will be the preferred option (over having to re-solder components on a device) by most consumers. It certainly is for me.
