Started: Use the BOM tool to find all non-generic components missing the Manufacturer Part Number property; for each such component, research distributor stock availability and update the Manufacturer Part Number component property to the best matching in-stock part.

Using BOM Tool.

Starting 2 component searches

Dispatching Library tool to find: "Terminal block 2 position 3.5mm"

Creating search plan for: "Terminal block 2 position 3.5mm"

Searching: "Looking for a PCB-mounted terminal block used for connecting wires. This is a general search to capture various terminal block types to identify parts that offer a board connection interface."

Searching: "Seeking a terminal block that specifically has 2 positions with a 3.5mm pitch. The part should be optimized for PCB mounting and is intended for secure, reliable wire connections in applications with moderate current handling and signal routing."

Searching: "Terminal block 2 position 3.5mm"

Searching: "Seeking a PCB-mounted header connector with 4 positions and a 0.1 inch pitch. The part is intended for standard through-hole mounting to provide reliable cable or board-to-board connectivity in general-purpose applications."

Searching: "In search of a 4-position header connector designed for PCB applications with a 0.1 inch pitch. The header should meet standard form factors for through-hole designs, ensuring compatibility with common cable assemblies and board mount configurations."

Found 51 results.

Searching: "Header 4 position 0.1"

General (prev)

Decision: I will update Manufacturer Part Numbers only for connector-type parts that clearly need a real MPN and have good in-stock distributor matches (the MCU 4-pin through-hole header and the CANBUS 2-position terminal block). I will not change template resistor/capacitor parts (they are ambiguous templates); recommend converting them to system-generic parts or specifying exact values/footprints before assigning MPNs. Proceeding to set MPNs for MCU and CANBUS.
