01
Find a defensible alternate.
Start from the incumbent part and the reason you need to replace it. Inrush Flow organizes the requirements first, then compares candidate parts against what actually matters.
Component intelligence
Can’t find a part? Paying too much? Need a second source?
Give Inrush Flow the part you have. It works through the technical requirements, reads the relevant datasheets and application notes, and helps you identify alternatives worth engineering review.
Start free. No fabricated “match score,” no paywall before you can try the workflow.

One workflow, three outcomes
Component work without the tab explosion.
Use the same technical engine whether the problem starts with sourcing, a design question, or a BOM-cost target.
02
Ask the technical question.
Instead of hunting through long PDFs, ask a direct question across datasheets and application notes and keep the answer tied back to the source material.
03
Reduce BOM cost intelligently.
Surface parts worth reviewing for cost, second-source exposure, lifecycle risk, or availability—without treating “similar” as “drop-in.”
How it works
Start with the part you already know.
01
Tell Inrush Flow what is wrong.
Unavailable, long lead time, pricing pressure, EOL, or simply the need for a second source.
02
Build the engineering requirement.
Relevant datasheets and application notes are used to organize the electrical, package, thermal, control, and application constraints that should drive the comparison.
03
Review alternatives with context.
See where a candidate aligns, where it differs, and what still needs engineering judgement before a substitution is approved.
04
Ask for commercial help only when you want it.
If you need pricing, availability, samples, or a supplier conversation, you can explicitly request an introduction.
Pricing
Useful free. Worth paying for when it becomes part of your workflow.
Start with individual component work. Upgrade when you need deeper analysis, more volume, and BOM-level workflows.

EARLY ACCESS
Pro
$49 / month
For engineers and procurement users who work through component decisions regularly.
- Higher usage and deeper research
- Multi-part comparison
- Advanced alternate analysis
- BOM cost-down workflows
- Saved work and exportable reports
