AFE5401TRGCRQ1 is a specific Texas Instruments orderable for the AFE5401-Q1, a four-channel analog front end (AFE) used in automotive radar baseband receive paths. When this number appears on an approved bill of materials, a useful sourcing answer needs more than a matching family name. The package, reel format, rated operating conditions and interface assumptions all affect whether a quoted lot can be used without further review.

TI lists AFE5401TRGCRQ1 as an active, production orderable. LimChip reports 4,000 units on hand with date code 2526 as of October 26, 2026. This is a dated availability statement, not a commitment for a particular lot or shipment date. Confirm the remaining quantity, packaging and price when requesting a quote.

Product overview and application scenarios #

TI lists automotive radar, data acquisition and SONAR among the AFE5401-Q1's applications. In a radar receive board, an RF front end first downconverts the received signal; the resulting baseband signals enter the AFE, and an FPGA or DSP captures its digitized output. The AFE is the conditioning and conversion stage between those blocks, not a radar RF transceiver or a complete radar sensor. TI also describes four auxiliary inputs that can bypass the main gain path to digitize monitoring signals such as battery voltage or temperature.

These examples explain where the device can fit, rather than establish compatibility with every radar or acquisition design. The signal bandwidth, input levels, clocking and software capture scheme still have to match the actual board.

Each of the four channels integrates a low-noise amplifier, programmable equalizer, programmable gain amplifier, antialias filter and 12-bit, 25-MSPS analog-to-digital converter. The four channels sample simultaneously, and their digital results are multiplexed onto a 12-bit parallel CMOS output bus. This combination reduces the number of separate receive-chain components, but it also makes the AFE's gain, filter and digital timing settings part of the system design.

For context, the PGA supports 0–30 dB of gain in 3-dB steps, and the selectable antialias-filter bandwidths are 7, 8, 10.5 and 12 MHz. The device uses 1.8-V and 3.3-V supply rails. A replacement decision therefore cannot be based solely on “four channels” or “12-bit ADC”: the input conditioning, sampling behavior, power rails and capture interface need to match the validated radar board.

The output is especially easy to misread from a short catalogue description. Four converters do not mean four independent 12-bit output buses. A controller or FPGA must capture the multiplexed bus with the specified data clock and synchronization signals, then associate samples with the correct channels. If the original design or firmware is unavailable, confirm this interface before proposing a different AFE.

What the exact AFE5401TRGCRQ1 orderable specifies #

TI's ordering information identifies this code as a 64-pin VQFN in the RGC package, measuring 9 × 9 mm. It is supplied on a large tape-and-reel of 2,000 devices. TI lists moisture sensitivity level 3 and an ambient operating range of −40 to +105 °C for this orderable. The 2,000-piece reel quantity describes the factory packaging option; it is not proof that 2,000 devices are available to ship or that a supplier will require a 2,000-piece minimum order.

AFE5401TRGCTQ1 is another listed orderable with the same RGC package but a 250-piece small reel. That packaging difference can matter to assembly and purchasing even when the underlying device is the same family. A buyer should not silently change an approved BOM from the RQ1 orderable to the TQ1 orderable: confirm the accepted manufacturer number and packing requirement with the customer or engineering owner.

There is also a temperature-label trap. TI describes AEC-Q100 Grade 1 qualification in the product documentation, while its recommended ambient operating condition and ordering information give −40 to +105 °C for AFE5401-Q1. Grade 1 wording is not a license to treat this device as guaranteed for +125 °C operation. If the radar module's ambient requirement exceeds +105 °C, resolve the specification with TI and the design team before sourcing or substituting.

LimChip supply and quote checks for AFE5401TRGCRQ1 #

LimChip's reported on-hand quantity on October 26, 2026 is 4,000 units with date code 2526. A factory large reel contains 2,000 devices, but the stock figure alone does not tell a buyer how many sealed reels are available or whether a quoted quantity would be split from a reel. Those are shipment details to confirm with the lot offer.

For an exact-code inquiry, start with the complete AFE5401TRGCRQ1 number and the board's approved manufacturer list. Request a quote that states quantity, unit price, currency, location, available-to-ship date and whether the offer is for original sealed large reels, opened reels or cut tape. A partial-reel offer may be useful, but the buyer should ask how lot identity, reel labeling and MSL handling were preserved.

Then verify the manufacturing lot and date code against the customer's acceptance rule, together with traceability to an authorized or otherwise approved source. The date code alone does not prove authenticity, and a claimed reel quantity does not prove current physical stock. For production builds, compare package marking, reel label, purchase trail and any requested quality documents before the order is released.

Keep design qualification separate from procurement convenience. AFE5401TRGCTQ1 changes the packaging quantity; AFE5401-EP and other similarly named devices should not be treated as automatic alternatives. Any proposed change needs the appropriate electrical, mechanical, temperature, interface and customer-approval checks. If the existing board has already been validated around the multiplexed CMOS output, that interface review is as important as the 64-pin footprint.

The most useful answer to an AFE5401TRGCRQ1 search is therefore an exact-lot answer: the precise orderable, traceable quantity, packaging condition and realistic shipment commitment, checked against the design's +105 °C operating limit and receive-chain interface. Those details let a buyer decide whether an offer fits the approved radar BOM without turning a single sourcing inquiry into an unsupported market-shortage claim.
