Technical qualification
The platform doesn't just find similar parts. It compares technical characteristics and explains the differences.
- Structured parameter comparison
- Deterministic engineering rules
- AI-assisted datasheet analysis
Component shortage resolution · In development

PASSGD32F405RGT6·Detailed reasoning
Every compared parameter is satisfied by the available documentation: identical LQFP-64 package and footprint, operating voltage within the 1.8–3.6 V window, a compatible −40 to +85 °C temperature range, and a matching pin configuration. One minor electrical difference (I/O drive strength) is noted for review but does not affect drop-in use in typical designs. Each conclusion links back to the specific datasheet page it came from.

The Problem
One unavailable component can trigger days of searching work
When a part is discontinued, out of stock, or has an unacceptable lead time, an engineer has to investigate a viable alternative by hand.
Search datasheets
Track down official manufacturer documentation for candidate parts and read through dense PDFs.
Compare specifications
Line up voltage, current, frequency, memory and temperature ratings parameter by parameter.
Check package & pinout
Confirm the footprint, dimensions and pin configuration to avoid a costly PCB redesign.
Verify across distributors
Check multiple distributors to see whether a technically suitable part is actually purchasable.
For a single difficult component this can take hours — sometimes days.
How It Works
From an unavailable MPN to a sourceable replacement
A combination of deterministic engineering rules, structured component data and AI-assisted datasheet analysis.
- 01
Enter the MPN
Enter the unavailable manufacturer part number, e.g. STM32F405RGT6. BOM upload is planned for a future version.
- 02
Analyse technical requirements
The platform extracts structured characteristics — package, pinout, voltage, ratings, temperature — primarily from official manufacturer documentation.
- 03
Find & qualify alternatives
Candidate part numbers are compared against the original and each parameter is marked PASS, FAIL or UNKNOWN with its evidence.
- 04
Check real availability
Distributor APIs are queried for current stock, pricing and lead time, so you see which qualified candidates are obtainable.
Example result
Technical qualification, not a black-box score
For each candidate the platform shows what matches, what differs, and what an engineer must verify — with the source behind every parameter.

Verdicts are decision support for engineers. Final engineering approval always remains with your team.
Built for engineers
Evidence, transparency, and explicit uncertainty
A decision-support tool for engineering teams — not an autonomous replacement authority.
Evidence-based results
Every conclusion points to where the technical information came from, ideally the relevant datasheet page.
- Manufacturer datasheets
- Traceable sources
- No black-box claims
Explicit PASS / FAIL / UNKNOWN
Uncertainty is never hidden behind a score. If a parameter can't be verified, it's marked UNKNOWN.
- Known matches → PASS
- Known incompatibility → FAIL
- Insufficient data → UNKNOWN
Procurement + engineering in one place
Answer both questions together: is this technically compatible, and can I actually buy it right now?
- Multi-distributor availability
- Independent of any single supplier
- Stock, pricing and lead time
Availability sources
One search, many distributors
The platform is designed to check availability across many distributors instead of being tied to a single supplier. We are actively working on these integrations.

Join the early access program
Help shape a tool built around how your team actually resolves component shortages.
AltComponent is currently in development. We're partnering with a small number of electronics manufacturers, EMS companies and engineering teams to validate the workflow against real shortage cases. Early access members get hands-on input into the roadmap and priority onboarding when the platform opens up.
- Share the component shortage cases you deal with today
- Try the MPN → qualification → availability workflow on your own parts
- Influence which distributor integrations and parameters we prioritise
- For engineering & procurement teams
- No pricing during validation
- No commitment — a conversation first
