For engineers reviewing the RI-TRP-RR2B-20 datasheet, RI-TRP-RR2B-20 application, RI-TRP-RR2B-20 equivalent, or RI-TRP-RR2B-20 physical dimensions and environmental rating, this page provides verified technical context, pinout-free mechanical specifications, real-world use cases, and qualified alternative options aligned with TI's production-grade transponder family.
Technical Context
The RI-TRP-RR2B-20 implements half-duplex (HDX) modulation using FSK at 134.2 kHz and 123.2 kHz carrier frequencies, enabling robust bidirectional communication without an onboard power source. Its resonant LC circuit-formed by integrated antenna inductance and tuning capacitance-is factory-optimized via TI's patented tuning process to ensure consistent coupling across readers.
It supports 17 read/write pages (1360 bits total), operates from –25°C to +85°C, and achieves ≤100 cm typical read range and 30% programming range under standard RF field conditions. The device is hermetically sealed in borosilicate glass, providing IP68-level protection and immunity to moisture, chemicals, and nonmetallic obstructions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar passive LF RFID transponder applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RI-TRP-WR2B-20 | Same glass package and 134.2 kHz HDX operation, but uses WPT (write-protected transponder) memory architecture with 1024-bit capacity and no user-programmable pages | Suitable only for fixed-ID applications like pet microchips; lacks R/W capability required for dynamic asset logging | Select RI-TRP-WR2B-20 when write security and immutability are prioritized over field-updatable data storage |
| RI-TRP-DR2B-40 | Identical electrical specs and glass form factor; differs only in ordering suffix (-40 vs -20) indicating tape-and-reel packaging quantity (2000 vs 1000 units per reel) | No functional or application difference; both support identical reader ecosystems and environmental deployments | Choose RI-TRP-DR2B-40 for higher-volume procurement where reel size aligns with SMT line efficiency |

FAQ
What is the operating frequency and modulation scheme of the RI-TRP-RR2B-20?
The RI-TRP-RR2B-20 operates at a fixed resonance frequency of 134.2 kHz using half-duplex (HDX) FSK modulation with carrier shifts between 134.2 kHz and 123.2 kHz. This enables reliable power harvesting and data exchange in passive RFID systems without internal clock sources or batteries, and is fully compliant with ISO 11784/11785 reader requirements.
Is the RI-TRP-RR2B-20 suitable for implantation in animals?
Yes, the RI-TRP-RR2B-20 is explicitly designed for animal identification applications. Its hermetically sealed borosilicate glass capsule meets biocompatibility and sterilization requirements for subcutaneous implantation, and its ISO 11784/11785 compliance ensures compatibility with veterinary scanners and national livestock databases worldwide.
Does the RI-TRP-RR2B-20 require external power or a battery?
No, the RI-TRP-RR2B-20 is a fully passive transponder. It derives all operating power from the electromagnetic field generated by an external LF reader antenna, eliminating the need for batteries, wiring, or maintenance-making it ideal for long-lifecycle, maintenance-free deployments in remote or inaccessible locations.
What is the maximum read range and programming range of the RI-TRP-RR2B-20?
The RI-TRP-RR2B-20 achieves a typical read range of ≤100 cm and a programming range of approximately 30% of that value (≤30 cm) under standard ISO-compliant RF field conditions (110–150 A/m). Actual range depends on reader antenna design, orientation, and environmental factors such as nearby metal or moisture.
How many times can the RI-TRP-RR2B-20 be rewritten, and what memory architecture does it use?
The RI-TRP-RR2B-20 supports up to 100,000 programming cycles and uses a 1360-bit multipage transponder (MPT) architecture with 17 individually addressable read/write pages. This structure allows selective data updates-such as maintenance timestamps or ownership records-without erasing the entire memory, enhancing data integrity in dynamic tracking applications.
