What to do with Discontinued Electronic Components Sourcing [Solved]

TPSM63606 is out of stock now, but my PCB project needs this components model. The design was finished long ago but has not been manufactured yet. What can I do to find discontinued electronic components?

As raw materials shortage and the pandemic seriously impact electronic component manufacturing, many electronic components are discontinued, especially power management components. 

However, many PCB designs were done before the outbreak, and PCB designers can't change their product design. Finding discontinued electronic components is a priority in work schedules for many PCB designers and product managers.

PCB HERO , a one-stop PCB manufacturer and electronic component distributor, who has a small amount of discontinued electronic components inventory and provides free electronic components sourcing services, may help PCB designers and hardware engineers at this moment. You can contact PCB HERO by email at nancy@pcb-hero.com to get an instant quote.

Background of Discontinued Electronic Components

Why are many electronic components in shortage, especially power management components? Here is the background of discontinued electronic components:

Due to the pandemic impact, the power supply electronics and analog electronics giant Texas Instruments (TI) is forced to pause most of the manufacturing capacity of its factories in the Philippines and Malaysia. To keep the profit, TI leaves the limited capacity to manufacture the high-profit electronic components, and currently, AC/DC & isolated DC/DC switching regulators, battery management ICS, and DC/DC switching regulators are basically discontinued.

TI discontinued electronic components

For example, the electronic components with part numbers starting with "TPS" are discontinued, such as TPS55288, TPS63900, TPS55882, TPSM63603, etc.

The car chip giant STMicroelectronics (ST) is another electronic component manufacturer that has greatly reduced manufacturing capacity. Since this July, ST's factory in Malaysia has been forced to paused production many times due to the pandemic. Many of its products are now out of stock and unavailable to order, especially automotive products.

On ST's official website, you can find many discontinued electronic components, such as the automotive image signal processors STV0991 series, the motor driver ICs L9805E, L9903, L9904, L9908, etc.

Not only TI and ST but almost all other leading electronic components manufacturers are also facing limited manufacturing capacity and have discontinued some electronic components.

Finding Discontinued Electronic Components Inventory

When electronic components are unavailable to buy from the manufacturers, the only channel to find them is the distributors who have discontinued electronic components inventory. PCB HERO has a small amount of discontinued electronic components inventory

We are a one-stop PCB manufacturer as well as a global electronic components distributor with hundreds of procurement points around the world. Regardless of the global electronic components shortage, PCB HERO maintains its stable electronic components supply network and can purchase electronic components at bulk pricing.
