If a phone charging connector gets a friendly name like Type-C, you might expect industrial connectors to have equally friendly names. They do not. The part in this story is called 1TGB100052A1650, and despite the unpronounceable name, it quietly keeps a lot of industrial equipment running.
A Small but Critical Part
The part is a crimped contact used in ABB industrial switchgear products. Functionally, it works a bit like a USB connector, but for much bigger and more powerful equipment. It connects ABB low and medium voltage switchgear to the busbar, the main conductor that distributes power through the system.
To see why it matters, picture the system. Switchgear is the equipment that controls and distributes electrical power in industrial facilities. The busbar is the backbone that carries that power, and the crimped contact is the physical link between the two. Every bit of current flowing into the switchgear passes through that junction, so a worn contact there is not something that can be ignored.
It is small, not well known outside engineering circles, and easy to overlook. But it is a critical component in many industries. When these contacts wear out or fail, the switchgear they serve cannot simply be left running without them.
Two Bad Options
Here is the problem: ABB stopped manufacturing this contact and pushed a new type instead. That is a normal product decision for a large manufacturer, but it leaves owners of aging switchgear in a difficult position.
A customer of ours faced exactly this situation. Their switchgear needed replacement contacts, and the original part was discontinued. That left two bad options. Option one: rip out and replace the entire system to match the new contact type, which is very expensive. Option two: track down the rare original contacts, which most suppliers no longer carry. After a long search, the customer came to us.
Neither path is attractive. Replacing an entire switchgear installation means new equipment and major work, all to solve a problem caused by one small contact. And hunting for a discontinued part through the usual channels usually ends at legacy distributors, whose prices reflect exactly how rare the part has become.
Finding It in China
As with so many industrial components, these contacts are still manufactured in China. We found Chinese manufacturers producing this exact part, and we sourced it for the customer.
It is worth saying what we did not find. This was not a leftover warehouse of old stock. We found active manufacturers producing the part today, which matters for any customer who will need the same contact again in the future. China's manufacturing base is broad enough that production of a component can continue there long after the original brand has moved on to a new design.
The pricing made the search even more worthwhile. The contacts we found were several times cheaper than what legacy distributors charge for the same discontinued part. The customer kept their existing switchgear, avoided a full system replacement, and paid a fraction of the expected cost.
The Takeaway for Buyers
A discontinued part is not the same thing as an unavailable part. Manufacturers stop production for their own reasons, but the installed base of equipment keeps running for years, and somewhere in China's vast manufacturing network, someone is often still making what you need.
The hard part is knowing where to look. If you are searching for a hard-to-find industrial component, whether it is electrical, mechanical, or anything else, contact us and tell us what you need. Finding it is what we do.
