★★★★★ 9/10 NPS Score 9 out of 10 customers would recommend Z2 to a peer. Source: Z2 Customer Satisfaction Survey 2026
Z2 cross-references your at-risk semiconductor against 1B+ parts and scores form-fit-function alternates on package, ratings, temp grade, lifecycle, and compliance — one view, not a stack of datasheets.
Component engineers at leading OEMs run on Z2
I've found the comparison tool within Z2 to be very helpful. If I'm looking for a replacement part for an existing design, I can line up however many alternates I want to look at and look at the specs line by line and see where things are the same and see where things are different.
A real alternate has to clear package, electrical ratings, temp grade, compliance, lifecycle, and live inventory. Reconciling all of that by hand runs hours per part, and a "match" that is itself obsolete or noncompliant just re-creates the problem.
| Task | Without Z2 | With Z2 |
|---|---|---|
| Finding a form-fit-function alternate | Line up datasheets, reconcile specs by hand | Ranked A/B/C matches, scored against your part |
| Confirming the alternate is safe to design in | Check lifecycle and compliance in separate tools | Lifecycle, RoHS, REACH, and COO on every result |
| A part goes obsolete with no PCN | You find out when stock runs dry | Flagged ahead of time, with alternates attached |
A semiconductor cross is only a drop-in when the package fits and the ratings hold. Z2 normalizes these fields across hundreds of millions of parts so you compare like for like.
| Capability | All-in-one | Distributor cross-ref | Manual datasheets |
|---|---|---|---|
| Cross-reference across 1B+ parts | Yes | Partial | No |
| Form-fit-function parametric matching | Yes | Partial | Partial |
| A/B/C tiered match classification | Yes | No | No |
| Independent lifecycle forecast | Yes | No | No |
| RoHS / REACH compliance status | Yes | Partial | Partial |
| Country-of-origin data | Yes | Partial | No |
| Multi-factor part risk score | Yes | No | No |
| Live inventory across all sources, not one catalog | Yes | No | No |
| Screen a full BOM, not one part at a time | Yes | No | No |
Cross-reference search
Enter an MPN and Z2 scans hundreds of millions of parts for the closest form-fit-function alternates, then sorts them into A, B, and C tiers. An A cross is a clean drop-in. A C cross works but needs engineering review. Every result opens into a side-by-side spec comparison that flags each difference as minor, moderate, or major, so you see exactly what changed before you commit a part to the design.
Lifecycle intelligence
A match means nothing if the alternate is NRND or heading to obsolescence next quarter. Z2 carries a lifecycle forecast with 90%+ historical accuracy on every part, from a proprietary algorithm validated against real end-of-life outcomes. Around 150,000 components reach end-of-life each year, and a large share go obsolete with no manufacturer PCN, so Z2 flags at-risk parts ahead of the last-time-buy window instead of after stock runs dry.
Built-in risk score
Z2 scores every part on six factors: lifecycle, compliance, technology generation, market availability, supplier risk, and multi-sourcing. The score travels with each cross-reference result, so a strong parametric match that is single-sourced, noncompliant, or built on aging technology gets caught before it lands in your design. You compare candidates on risk, not specs alone.
Everything on this page is Part Risk Manager. It is one tool that cross-references 1B+ components, scores each part on lifecycle, compliance, and supplier risk, and surfaces the form-fit-function alternates you need the moment a semiconductor goes at-risk.

Enter an MPN or drag in a spreadsheet, CSV, or ERP export. Z2 reads it as-is, no column mapping.
Z2 returns A/B/C alternates with lifecycle, compliance, COO, and a six-factor risk score on each. Compare specs line by line.
Download the alternate comparison and risk data, or push results straight to your PLM for the redesign record.
Z2 scans hundreds of millions of parts for the closest form-fit-function matches, comparing package, electrical ratings, speed, temp grade, compliance, and lifecycle. Results are classified into A, B, and C tiers, where A is the closest drop-in and C needs engineering review. Each cross opens into a side-by-side comparison flagging every difference as minor, moderate, or major.
Z2 tracks 1B+ off-the-shelf components across 1,000+ commodity types. That includes ICs, microcontrollers, MOSFETs and power devices, analog, logic, diodes, voltage regulators, memory, and crystal oscillators.
Every part carries a lifecycle status and a forecast with 90%+ historical accuracy, from a proprietary Z2 algorithm. Z2 flags NRND and at-risk candidates so you don’t cross to a part heading for end-of-life. Around 150,000 components reach end-of-life each year, many with no manufacturer PCN, so the forecast matters.
Yes. Each cross-reference result carries RoHS and REACH compliance status and country-of-origin data, alongside Z2's coverage of 270+ regulations. You see compliance and sourcing exposure on a candidate before you design it in, not during an audit.
Distributor tools surface alternates within their own stocked lines and are biased toward what they sell. Z2 is independent: it spans 1B+ parts across manufacturers, adds lifecycle forecasting, a six-factor risk score, compliance depth, and live inventory across sources, not one catalog.
One platform for the full life of every part on your BOM.
