COMPONENT SOURCING / LEGACY SYSTEM SUPPORT
A missing part should have a clear next step.
Bring us the full part number and the date you need it. Request sourcing for obsolete chips, supply gaps and specialist components—or review another route for your design.
Start with my part number ↓Availability, price and delivery are confirmed by quotation. A part shown on this page is not a stock offer.
ONE REQUIREMENT, THREE POSSIBLE ROUTES
Tell us which constraints are fixed before considering another part.
For maintenance, a fixed BOM or a production shortage. Include the complete suffix, minimum usable quantity, date-code limits and permitted delivery splits.
Quotation checkpointSource evidence, condition, lot details, quantity, price and delivery—subject to confirmation.
Request exact-part sourcing →When another part is possible, define the function, footprint, power rails, interfaces, temperature range and software constraints.
Engineering checkpointA comparison of differences and validation work. Similar function does not establish drop-in compatibility.
Request an alternative review →If the original platform cannot be sustained, bring the BOM, board revision and acceptance requirements into a PCB/PCBA project review.
Manufacturing checkpointAgree design responsibility, DFM, component supply and programming or test scope before a build.

MANUFACTURER NOTICE DESK
Curated original-source summaries. Notice dates and our source-review dates are separate; historical deadlines do not indicate current availability.
NXP / 202506017DN
Historical deadline passedThe notice covers specific orderable parts, including MC14489BDWE and MC56F8002VWL. These rows list no replacement. Ask for an application review rather than assuming an equivalent device.
AMD / Xilinx / XCN23005
Historical deadline passedSelected Virtex-4, Virtex-5, Virtex-6 and Virtex-7 ordering numbers are listed for discontinuation, with no direct replacement. This is not a family-wide status. Revision 1.1 removed XC7VX330T-2FFV1761C and refers it to XCN20011.
AMD / Xilinx / XCN20011
Historical deadline passedFor XC7VX330T-2FFV1761C, the notice lists XC7VX330T-2FFG1761C as its historical replacement. Retain the notice and referenced package-change conditions; this does not establish current stock, current lifecycle or qualification of your board.
This selection is not a complete EOL feed. Confirm the latest manufacturer revision and the exact affected orderable part before making a purchase or lifetime-buy decision.
MAKE THE REQUIREMENT REVIEWABLE
No supplier relationship, component authenticity certification or test coverage is implied by a listing. The evidence and accepted scope belong in the quotation.
Check BOM completeness →Keep the original manufacturer recommendation with its conditions. A cross-reference is a starting point for review.
Compare reviewed FPGA specifications →
WHEN SOURCING CHANGES THE BOARD
A different package or device can change routing, power, programming and acceptance tests. Bring those changes into the same manufacturing brief.
Company and manufacturing evidence · Request handled by KB Group Co.,LTD
BEFORE YOU SEND A REQUEST
Yes. Send the complete manufacturer ordering number, manufacturer name and required quantity. Include a source document if the part uses an unusual designation. Catalogue coverage does not determine whether an enquiry can be reviewed.
This page does not publish live stock. The examples explain documented lifecycle cases. Availability, price, source conditions and delivery must be confirmed for the exact part and quantity in your quotation.
State the exact MPN, minimum quantity needed to restart, destination and required delivery date. Tell us whether split deliveries are useful and whether alternatives are allowed. Do not remove traceability or acceptance requirements to shorten the enquiry.
Not necessarily. TI distinguishes “not recommended for new designs” from last-time-buy and obsolete states. Check the manufacturer's status for the exact orderable part and its notice dates; temporary scarcity is a separate supply question. TI lifecycle definitions ↗
Only after the relevant compatibility checks and your approval. A similar function or manufacturer cross-reference alone does not establish matching pins, electrical behavior, firmware, FPGA configuration or thermal performance. Some alternatives require a board revision.
Tell us the source documentation, lot/date-code records, condition and acceptance evidence you require. Any inspection, electrical test, third-party work or reporting scope must be agreed before purchase. A quoted scope may contain exclusions; review these with your quality team.
Submit the requirement for review. Minimum quantities and viable sourcing routes depend on the exact component and available lot. We cannot promise that every discontinued part can be found.
YOUR REVIEW OUTPUT
Use one row per exact-code offer. This is an original enquiry worksheet, not a representation of available inventory.
| Record separately | Question to resolve | Keep open until confirmed |
|---|---|---|
| Exact identity and permitted changes | Does the offer match every character of the required MPN, or is it a proposed alternative? | Any difference in package, grade, speed or special suffix needs its own disposition. |
| Quantity and delivery window | What quantity can be offered for the required date, and are split deliveries acceptable? | A quotation request or old listing is not a confirmed allocation. |
| Lot, condition and documentation | Which lot/date-code, condition and source records are included in this particular offer? | Ask what is unavailable; do not assume the same records accompany every lot. |
| Inspection and acceptance | Which inspection or test outputs are proposed, what are the exclusions, and who accepts the result? | A planned test is not a completed test or a guarantee of application suitability. |
Keep a supplier’s commercial offer separate from the board change record. If an alternative is allowed, retain the original BOM code, candidate code, applicable manufacturer documents and the engineering verification owner. Comparing prices before aligning these conditions can hide differences that matter more than the unit price.
For an archived example of why table roles matter, XCN20011 v1.0, page 2, Table 4 distinguishes affected and replacement ordering codes. Its historical relationship does not establish the availability or acceptance evidence of a current offer. Source scope rechecked October 20, 2026.
