Solutions · Component Procurement

Sourcing for obsolete, allocated, and hard-to-find electronic components.

When your BOM lists a part that's discontinued, on allocation, or stuck at 52-week lead time, our sourcing team is built to find it. Authorized distribution network, verified excess-inventory sources, and global component sourcing channels — all vetted, all traceable, all documented.

Component procurement is the sourcing of electronic parts for a build, including obsolete, allocated, and hard-to-find components. RLX Solutions sources parts for engineers and procurement teams across four supply channels, with counterfeit verification and full traceability on every part.

01 — Overview

Sourcing built for the BOM you actually have.

Every active hardware program runs into the same problem eventually: a critical component goes obsolete, a whole package gets EOL'd by the manufacturer, or a silicon shortage pushes lead times past your ship date. The spec doesn't care. Your customer doesn't care. The part needs to be on the line.

We run a three-channel sourcing model: authorized distribution for routine parts (Arrow, Digi-Key, Mouser, Future, TTI, Avnet), a verified excess-inventory network for allocated and obsolete components, and a global component sourcing channel for parts that move only through specialized trading networks not accessible to direct purchasers. Every channel is vetted and every lot comes with traceability documentation.

Counterfeit prevention is built into the workflow — lot and date code verification, packaging inspection, visual acceptance to IDEA-STD-1010, and testing escalation (X-ray, decapsulation, electrical functional) when the source or part history warrants it. If we can't verify authenticity, we don't buy it.

02 — Sourcing channels

Three networks. One procurement manager.

You work with one point of contact. We run the channels behind the scenes.

CHANNEL / 01

Authorized Distribution

First-stop for active parts

Arrow, Digi-Key, Mouser, Future, TTI, Avnet, Rochester, Newark, and manufacturer-direct. Guaranteed authentic, factory-warranty intact, full datasheet support.

CHANNEL / 02

Excess Inventory Network

For obsolete & allocated parts

Vetted independent distributors and broker partners with authentic stock from OEM overbuys and program cancellations. Lot-traced, with test plan on request.

CHANNEL / 03

Global Sourcing Network

Channels unavailable to direct purchasers

Established relationships with specialized component trading networks — often the only route to obsolete parts, shortage-cycle allocations, and constrained inventory not available through standard distribution.

CHANNEL / 04

Customer Inventory

Consigned / customer-supplied

If you have existing inventory, we can use it alongside our sourced parts. Standard consigned workflow — you ship parts, we build.

03 — Counterfeit prevention

How we verify every part.

Source vetting
Authorized distributors only for active parts · qualified independent distributors with documented lot history for excess-inventory sourcing
Packaging inspection
Unopened original packaging preferred · moisture bag integrity · date code and country-of-origin match to manufacturer records
Visual inspection
IDEA-STD-1010 acceptability criteria · marking, surface finish, leads, and coplanarity under magnification
Lot verification
Cross-check lot / date codes against manufacturer production records where available
X-ray
Internal die and bondwire verification for higher-risk parts and counterfeit-prone packages
Electrical test
Sample functional testing · curve-trace · parametric verification on request
Escalation
Decapsulation and die analysis by third-party lab for highest-risk programs · reports delivered with shipment
Documentation
Certificate of Conformance (CoC) · traceability report · test data available per customer quality plan
04 — Common scenarios

When customers call us.

SCENARIO / 01
EOL Critical Part
Manufacturer discontinued a component mid-program. We find lifetime-buy stock and develop a last-time-build plan.
SCENARIO / 02
Allocation Shortage
Authorized distributor has the part on 52-week allocation. We source through verified excess-inventory channels.
SCENARIO / 03
Legacy Program Support
Running a 10-year-old design and the original components are rare. We trace, authenticate, and supply.
SCENARIO / 04
Drop-In Replacement Sourcing
Original part not available. We identify electrically and pin-compatible alternatives for your engineering review.
SCENARIO / 05
Counterfeit Risk Investigation
You bought parts that look wrong. We test, verify, and report — and source authentic replacements.
SCENARIO / 06
Cost Reduction
Authorized pricing killing your margin? We source authentic excess inventory at authorized-compatible cost with full traceability.
05 — Send your BOM

Give us the part that's blocking you.

Send your BOM or a list of the parts you can't find. We'll come back with availability, pricing, lead time, and traceability documentation.

Frequently asked questions

Can you find obsolete and end-of-life parts?
Yes. Obsolete, end-of-life, last-time-buy, allocated, and long-lead parts are the core of this service, sourced across authorized, excess-inventory, and global networks.
How do you protect against counterfeit parts?
A staged chain: source vetting, packaging and lot verification, IDEA-STD-1010 visual inspection, X-ray of the die and bond wires, electrical test, and third-party decapsulation for the highest-risk programs.
Where do the parts come from?
Four channels run by one procurement manager: authorized distribution first, then a vetted excess-inventory network, a global sourcing network, and your own inventory where you hold stock.
Can you source against my full shortage BOM?
Yes. Send the bill of materials, including the line items blocking your build, and RLX sources across all four channels and quotes with availability and lead times.
What documentation comes with sourced parts?
A certificate of conformance, a traceability report, and test data, supplied to match your quality plan.
Will you buy our excess inventory?
Yes. The procurement service runs a two-sided marketplace, so RLX buys verified surplus and obsolete stock as well as supplying it.
