Obsolete & Hard-to-Find Components

EOL ICs, legacy relays, discontinued connectors, replacement LCD modules. We search verified China surplus stock and specialty suppliers for parts distributors have dropped.

What We Source

EOL & NRND Integrated Circuits

Microcontrollers, op-amps, voltage regulators, ADCs, DACs, memory chips, interface ICs that manufacturers have discontinued. We search verified surplus distributors across China for remaining stock.

Legacy Industrial Relays & Timers

Obsolete relay part numbers no longer in production. We locate surplus stock and verified refurbished units matched to your existing socket or PCB layout.

Discontinued Connectors & Backplanes

Board-to-board, wire-to-board, and circular connectors discontinued by the original manufacturer. We find surplus stock or compatible alternatives that fit the original footprint.

Replacement LCD Modules & Displays

Character LCDs, graphic LCDs, OLED modules for legacy equipment panels. We match outline dimensions, resolution, interface, and mounting holes for drop-in replacement.

PLC Spare Parts

Legacy I/O cards, CPU modules, power supply modules, communication cards for older PLC systems. Surplus and refurbished condition. Tested before shipment where possible.

Short-Supply & Allocation Parts

Parts currently on allocation from major distributors with 26+ week lead times. We search alternative China channels for genuine stock available now. No fake inventory promises.

Sourcing Capability

How We Search

We check specialty surplus distributors, factory excess stock, and verified refurbishment channels in China — sources most international distributors don't access.

Condition Transparency

Every quote states: New Original (sealed), Surplus New (unused but older stock), Refurbished (tested), or Used Pull. Photos and date codes provided on request.

Realistic Expectations

Not every part is findable. We'll tell you honestly if we can't locate a component. When we do find it, condition may be surplus or refurbished — we never hide this.

Frequently Asked Questions

What's your success rate for finding obsolete parts?

We find approximately 60-70% of requested obsolete industrial components through our China surplus network. Success depends on how recently the part was discontinued. We always respond honestly.

What condition can I expect?

It varies — and we'll always tell you upfront. New Original (sealed) is rare for truly obsolete parts. More common: Surplus New (unused, older date codes) and Refurbished/Used Pull (tested, removed from decommissioned equipment).

How long does searching take?

Initial response within 48 hours. For deeper searches across multiple surplus channels, it may take 3-7 business days. We'll keep you updated throughout the process.
