|---|---|---|---|
| FFF Compatibility | Requires a layout redesign to switch from a 30-pin Through-Hole (THT) dual-in-line layout to a 34-pin Surface-Mount (SMD) pattern.Features a smaller physical size and SMD mounting style compared to the larger THT DIL package of the queried module.Provides full functional parity including operating frequency (134.2 kHz), voltage range, serial TTL/USB interfaces, and protocol support. | Physically plugs into the same 30-pin socket, but pins 7, 8, 9, 11-14, 23, and 28 are reserved/unconnected on this older module.Uses the exact same Through-Hole DIL module package and board outline.Lacks the USB interface, auxiliary general-purpose input/output (GPIO) control pins, and advanced HDX transponder programming features of the MRD2. | |
 AI Summary | RI-STU-MRD2 by Texas Instruments: RFID Reader Module 134.2kHz Module. | The RI-SMD-MRD2 is the surface-mount sibling of the RI-STU-MRD2, offering the exact same RFID reader/writer core capabilities and interface options in a more compact package. It is an ideal alternative if you can accommodate a PCB footprint redesign.
| The RI-STU-MRD1-30 is the predecessor in the same DIL form factor. While it is physically pin-compatible, it lacks USB capability and the advanced firmware features of the MRD2, and is currently classified as obsolete.

You searched one part. Parter watches your whole BOM.
All your BOM, at once
Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.
Hear about problems before they hit production
Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.
Qualified replacements in minutes, not days
Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
Frequently asked questions
Yes. The Texas Instruments RI-STU-MRD2 is active and in production. The parts listed here are qualified equivalents if you need a second source or better availability.
The closest qualified second sources for the Texas Instruments RI-STU-MRD2 are the RI-SMD-MRD2 (Texas Instruments) and the RI-STU-MRD1-30 (Texas Instruments). Each is compared against the original on fit, form and function in the table above.
Not always. The alternatives to the RI-STU-MRD2 are matched on function but can differ in package, pinout or a key parameter, so review the fit/form/function notes in the table and the datasheet before designing one in.
The RI-STU-MRD2 (Texas Instruments) is a part in the RFID Reader Modules category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
