AI agent for electrical engineers

Component Selection and BOM Agent

A complete bill of materials with parts that meet specs, are available and fit the budget

Component Selection and BOM Agent: what goes in, what the agent does and what you get

What it does

Choosing parts means matching each requirement against datasheets and then checking footprints, stock, lead time, price and lifecycle, which takes hours per board. This agent takes the requirements for each component, searches approved suppliers and distributors, and shortlists parts that meet the electrical and mechanical specs. It checks availability, lifecycle status and price against the budget, then builds the bill of materials. Before finalizing, it rechecks the full list for single-source parts and lead times past your limit. Where no part meets every requirement, it lists the closest options with the trade-offs instead of silently relaxing a spec. You approve the final selections. Edge case: a cheaper part that meets specs but is marked not recommended for new designs is flagged, not chosen on price.

How it works

Follow the arrows from top to bottom. The orange dashed arrow is the loop: when a check fails, the agent goes back and tries again.

How it decides

A part qualifies only when it meets every electrical and mechanical spec and is available; it never relaxes a spec without flagging it.

  • Qualify a part only if it meets every spec
  • Flag single-source and long-lead parts
  • Never choose on price alone when lifecycle is at risk

Make it yours

Every agent is a starting point. You choose these settings for your own situation.

  • Approved suppliers
  • Budget and price limits
  • Lead-time limit that flags risk
  • Required spec margins

What keeps you in control

It always asks you first

  • Final part selections and the bill of materials

Hard limits

  • Never places orders
  • Does not relax a spec without flagging it

It stops when

  • Done: bill of materials complete within budget
  • Stop: requirements for a component are undefined

An example run

What happensFor the voltage regulator on the Rev C controller board at Northpoint Controls, the agent shortlisted three parts meeting current and thermal specs. The cheapest failed the lifecycle check as not recommended for new designs, so it recommended the second, in stock with a 6-week lead. A connector was single-source and flagged. The hardware lead approved the BOM on July 9.
