It delivers stable read/write performance in access control and asset tracking applications.
For engineers reviewing the RI-TRP-WR2B-30 datasheet, RI-TRP-WR2B-30 application, RI-TRP-WR2B-30 equivalent, or RI-TRP-WR2B-30 physical dimensions, this page provides verified technical context, pinout-free package details, real-world use cases, and validated alternative transponders for low-frequency RFID system design and deployment.
Technical Context
The RI-TRP-WR2B-30 implements TI's patented HDX (half-duplex) modulation scheme using FSK at 134.2 kHz and 123.2 kHz, enabling simultaneous power harvesting and bidirectional data exchange without an onboard power source. Its resonant LC circuit is factory-tuned for consistent coupling across varying reader antenna configurations.
It operates within 0–70°C for programming and –25–85°C for general use, with hermetic glass encapsulation ensuring immunity to moisture, chemicals, and nonmetallic material interference. The transponder supports up to 100,000 programming cycles and delivers typical read range ≤100 cm and programming range at 30% of read range.

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-DR2B-40 | Same glass package, identical 134.2 kHz HDX operation, ISO 11784/11785 compliance, and 1360-bit MPT memory; differs only in part marking and packaging quantity (2000/reel vs. 30/unit) | No functional difference; intended for same access control, vehicle ID, and asset tracking roles | Select RI-TRP-DR2B-40 when volume procurement or reel-based automated assembly is required |
| EM4102-32 | 125 kHz frequency, fixed 64-bit read-only memory, no write capability, no ISO 11784/11785 support, epoxy encapsulation instead of glass | Limited to basic read-only identification where regulatory compliance and rewritability are not required | Choose EM4102-32 only for cost-sensitive, low-security, short-range applications with legacy 125 kHz readers |
Compared with RI-TRP-DR2B-40, RI-TRP-WR2B-30 offers identical RF performance and memory architecture but ships in smaller quantities for prototyping and low-volume deployment; versus EM4102-32, it provides ISO-compliant rewritability, superior environmental resilience, and extended read range at the cost of higher unit price and 134.2 kHz reader dependency.

FAQ
What is the operating frequency of the RI-TRP-WR2B-30 and why does it matter?
The RI-TRP-WR2B-30 operates at 134.2 kHz, matching the internationally standardized LF band for animal identification and access control. This frequency enables deep material penetration and strong magnetic coupling with reader antennas, making RI-TRP-WR2B-30 ideal for reading through barriers like plastic, wood, or tissue-critical for embedded and implantable use cases.
Is the RI-TRP-WR2B-30 compatible with ISO 11784 and ISO 11785 readers?
Yes, the RI-TRP-WR2B-30 is fully compliant with both ISO 11784 (coding structure) and ISO 11785 (air interface protocol). This ensures seamless interoperability with certified LF readers used in livestock management, vehicle access, and global logistics infrastructure-no firmware or protocol adaptation is needed when deploying RI-TRP-WR2B-30.
Does the RI-TRP-WR2B-30 require a battery or external power source?
No, the RI-TRP-WR2B-30 is a fully passive transponder. It harvests operating energy directly from the reader's 134.2 kHz magnetic field and uses that power to run its internal circuitry and transmit data. This eliminates battery replacement, reduces size and cost, and ensures indefinite operational life-key for RI-TRP-WR2B-30 deployments in inaccessible or sealed locations.
What is the maximum number of times the RI-TRP-WR2B-30 can be rewritten?
The RI-TRP-WR2B-30 supports up to 100,000 programming cycles across its 17 R/W memory pages. This endurance rating is validated under standard operating conditions (0–70°C) and enables long-term reuse in dynamic applications such as rental equipment tracking, smart bin management, and configurable access credentials-without degradation of RI-TRP-WR2B-30 functionality.
How does the glass encapsulation of the RI-TRP-WR2B-30 improve reliability compared to epoxy alternatives?
The RI-TRP-WR2B-30 uses borosilicate glass encapsulation, providing hermetic sealing against moisture, chemicals, UV radiation, and thermal shock. Unlike epoxy-packaged transponders, which may delaminate or absorb humidity over time, the glass body maintains structural integrity and electrical performance across –25°C to +85°C-making RI-TRP-WR2B-30 suitable for implantation, outdoor vehicle ID, and industrial washdown environments.
