Switch from SiliconExpert to Z2.

Z2 brings component intelligence, compliance, lifecycle forecasting, and supply chain risk into one platform — a BOM-level view that connects part data to the risk, alternates, and country-of-origin picture behind every line.

  • Full BOM risk scored and rolled up
  • Pre-mapped, ready-to-buy alternates
  • Country of origin and tariff data

Sourcing and supply chain teams at leading OEMs run on Z2

The level of insight that it was able to give us was far superior to what we had seen before with our incumbent solution.

Part-by-part lookup doesn't tell you your risk.

A part-search tab answers one MPN at a time. It can't tell you which of your 2,000 lines is about to go obsolete, which ship from a tariffed origin, or where your only second source already exists.

Topic Without Z2 With Z2
Obsolescence You learn of the EOL after stockout Z2 lifecycle forecast flags it early
Alternates Weeks hunting and qualifying by hand A/B/C cross-references pre-mapped
Tariff exposure A surprise on the customs invoice Country of origin and HTS on every line

Everything you need to know about a component.

Other tools give you parametrics and a datasheet. Z2 attaches the full risk and sourcing picture to the same MPN, so one record answers what a separate tool, a distributor site, and a compliance database used to.

Obsolescence forecast
A forecast obsolescence date on every part, validated at 90%+ historical accuracy, so you design out dying components before they stall a build.
Six-factor health score
One score rolls up lifecycle, compliance, availability, and supplier signals, so the riskiest lines on a BOM surface in seconds instead of a manual audit.
Form-fit-function alternates
Z2 grades every alternate A, B, or C by form, fit, and function, so the closest drop-in and the swap risk are clear at a glance.
EU RoHS status
Per-part RoHS results resolved at the homogeneous-material level, so a compliance gap is flagged on the component, not buried in a supplier declaration.
Country of origin + HTS
Country of origin and HTS classification on every component, so you can model tariff exposure and see which BOM lines a Section 301 change actually hits.
Distributor pricing
Live pricing and stock from licensed distributors and vetted broker sources, so the part you spec is one you can actually buy today.

BOM Rollup

One BOM, one risk view.

A part-search tool answers one MPN at a time, so a 2,000-line BOM means 2,000 separate lookups and no collective answer. Z2 reads the whole bill of materials at once and returns the exposure that matters at the program level: how many lines face obsolescence, how many carry a restricted substance, how many trace to a single source. The verdict you used to assemble by hand is the first screen you see.

Alternates

The second source, already mapped.

When a part goes NRND or hits last-time-buy, the clock starts and finding a qualified replacement by hand takes weeks. Z2 pre-maps form-fit-function alternates for every component in A/B/C tiers, where A is the closest match and C needs engineering review. Each alternate is filterable by country of origin, lifecycle status, and availability, so the replacement you reach for is already screened against the same risks as the original.

Tariff Layer

Country of origin on every line.

A datasheet says nothing about where a part is made, so tariff exposure stays invisible until the invoice arrives. Z2 carries country of origin, country of diffusion, and HTS classification on every component, mapped back to the manufacturing site behind it. When Section 301 rates move, you already know which BOM lines are exposed and where the sites that build them sit.

Questions sourcing teams ask first.

We already use SiliconExpert. Why add Z2?

They answer different jobs. A part-search tool is the engineer’s daily lookup for parametrics and datasheets. Z2 is the risk and sourcing layer the procurement and supply chain side needs: BOM-level rollup, six-factor risk scoring, pre-mapped alternates, and a country-of-origin layer on every line. Most teams run Z2 alongside what engineering already uses.

How accurate is the obsolescence forecast?

Z2’s lifecycle forecasting uses a proprietary algorithm validated against real end-of-life outcomes, with 90%+ historical accuracy. It projects an obsolescence date per part so you can qualify a replacement before stockout, instead of learning of an EOL after the fact.

How much of my BOM is covered out of the box?

Z2 tracks 1B+ off-the-shelf components across 1,000+ commodity types, and part-to-site mapping covers roughly 70% of the off-the-shelf components in a typical BOM on day one. Coverage starts the day you upload.

Can Z2 handle tariff and country-of-origin questions?

Yes. Z2 carries country of origin, country of diffusion, and HTS classification on every component, mapped to the manufacturing site behind it. That lets you model tariff impact across a full BOM, line by line.

Part data is just the beginning.

The same record feeds compliance, sourcing, and supply chain risk. One part entered once is visible across all three.
