Q3 2026 Price Deadlines: Microchip Aug 14, TI Sep 15, KEMET Tantalum and the Xilinx Spot Rally

What changed #

The July 2026 repricing wave was a reset point. The difference in August and September is that several increases now carry hard effective dates, which means the buying window is measured in days, not quarters. Three deadlines matter most for procurement teams right now.

These are not the same as the broad July 1 adjustments already covered in the July price-increase watch. They are dated, manufacturer-level notices with a specific cutoff, which is exactly the signal that should trigger a re-quote rather than a market-level assumption.

The Xilinx spot rally is a separate, faster-moving signal #

While the price-list deadlines above move on a calendar, the Xilinx (AMD) spot market is moving by the week. Market updates through late July and early August 2026 report two-week moves of roughly XC7Z020-2CLG484I +15%, XC7A75T-2FGG484I +10% and XCKU5P-2FFVB676I +16%, with futures lead times pushed beyond 50 weeks (versus 8–12 weeks in 2025) and selected part numbers no longer accepting futures orders. With capacity directed toward AI programs, factory shipments of mainstream XC7A / XC7Z series through the first half of 2026 were reported as minimal, leaving traders releasing stock in single-reel batches.

Both XC7Z020-2CLG484I and XC7A75T-2FGG484I are carried in the LimChip database, so the practical question for buyers is not "is Xilinx tight" — it is "how much of my open Xilinx demand is still uncovered past the current quote validity."

Why buyers should care #

A dated price-list increase and a spot rally pull in opposite directions on timing. The list increases reward early PO release against old pricing; the spot rally rewards locking any available qualified stock before the next weekly move. Both punish the same habit: letting a quotation sit past its validity window.

The wider context has not softened. Analog Devices has notified customers that selected lead times have extended to about six months. STMicroelectronics MCU lead times were reported at 52–54 weeks, with distributors confirming full-year 2027 order requirements. Standard-series FPGA lead times generally exceed 40 weeks, with industrial, automotive and high-reliability grades at 52 weeks. Texas Instruments BQ-series battery-management ICs were quoted at 22–28 weeks with scarce spot, and high-precision industrial ADCs around 30 weeks. Infineon power devices show MOSFETs at 24–32 weeks and IGBTs at 26–52 weeks.

The through-line is that quotation validity is contracting while lead times stretch, so the cost of waiting is no longer just a possible price move — it is the risk of dropping to the back of a multi-quarter queue.

Affected component areas #

• Tantalum capacitors — KEMET MnO2 parts up to +25%, polymer about +5% from

Aug 1; relevant to power-stage bulk capacitance and legacy-design holdover.

• Xilinx / AMD FPGA and SoC — Artix-7, Zynq-7000 and Kintex UltraScale+ spot

premiums and 50+ week futures; design-critical and hard to second-source.

• Power management and MOSFETs — TI TPS / TLV / BQ / UCC families facing the

Sep 15 increase; Infineon MOSFET / IGBT on extended lead times.

• MCUs and analog — Microchip full-portfolio reprice Aug 14; ST and ADI

long lead times on selected lines.

• Passives broadly — tantalum follows the MLCC and resistor tightening

already noted in mid-2026 passives reporting.

RFQ and sourcing checks #

Practical takeaway #

Treat the next five weeks as a deadline-driven re-quote cycle, not a market commentary exercise. Pull fresh pricing and delivery for every line touched by the Aug 1 (KEMET tantalum), Aug 14 (Microchip) and Sep 15 (TI) dates, and separately confirm any open Xilinx demand against quote validity before the next spot move. Confirm the full ordering code, date code, lot consistency and traceability on every offer — a higher price is only defensible when it is backed by the exact lot and delivery terms, not by a general "market increase."

The LimChip part database can locate exact ordering-code pages for KEMET tantalums and Xilinx FPGAs, and the RFQ form can capture quantity, date-code and package needs in one request.

Sources and interpretation boundary #

This update draws on distributor market updates (UnikeyIC Market Updates 2629 and 2632, August 2026), an August 2026 component supply-chain insight roundup, and a reported TI price-increase notice dated 2026-08-11. Manufacturer notices can vary by customer, region and product family, and spot figures are indicative of trader pricing rather than confirmed list prices. Current stock, date code, lot condition, lead time and final pricing must be confirmed by RFQ before purchase.
