Product details
Overview
RI-TRP-RE2B-30 from Texas Instruments is a 32 mm glass LF RFID transponder operating at 134.2 kHz, compliant with ISO 11784/11785, featuring 64-bit read-only memory, HDX half-duplex transmission, and hermetic glass encapsulation for industrial asset tracking. It draws power exclusively from the reader's RF field and delivers stable read performance in access control and container identification systems.
For engineers reviewing the RI-TRP-RE2B-30 datasheet, RI-TRP-RE2B-30 pinout, RI-TRP-RE2B-30 application, or RI-TRP-RE2B-30 equivalent, key selection considerations include its batteryless operation, 134.2 kHz resonance, HDX modulation scheme, 70 ms typical read time, and glass package rated for –25°C to +70°C read operation.
Technical Context
The RI-TRP-RE2B-30 implements Half-Duplex (HDX) communication using Frequency Shift Keying (134.2 kHz / 123.2 kHz), requiring precise reader-side timing synchronization for reliable data exchange. Its passive architecture eliminates onboard power sources, relying entirely on magnetic coupling from the reader antenna.
It uses a tuned LC resonator formed by internal coil and capacitor, manufactured via TI's patented transponder tuning process to ensure consistent 134.2 kHz resonance and high read/write stability across environmental variations. Memory is factory-programmed and immutable-no programming capability is supported.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Frequency | 134.2 kHz - precisely tuned resonance enables interoperability with ISO 11784/11785-compliant readers |
| Memory Capacity | 64-bit read-only - fixed ID storage; no user reprogramming allowed |
| Transmission Principle | HDX (Half-Duplex) - separates reader transmit and transponder reply in time, reducing interference |
| Power Source | Batteryless - powered solely by reader's RF field; eliminates maintenance and lifetime limitations |
| Typical Read Time | 70 ms - defines minimum dwell time required per tag interrogation in high-throughput systems |
| Read Range | ≤100 cm - achievable under optimal conditions (reader antenna design, regulatory limits, non-metallic environment) |
| Operating Temp (Read) | –25°C to +70°C - specifies functional envelope for deployment in outdoor access gates or waste bins |
Pinout & Package
RI-TRP-RE2B-30 is a monolithic glass-encapsulated transponder with no external pins or terminals. It contains an integrated coil and capacitor forming a sealed resonant circuit; electrical interface is exclusively via inductive coupling to a reader antenna.

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-WE2B-30 | 80-bit read/write memory; supports field reprogramming up to 10,000 cycles; same glass package and HDX protocol | Required where dynamic data updates (e.g., status flags, timestamps) are needed between reads | Select RI-TRP-WE2B-30 only if write capability and CRC-protected user memory are essential; otherwise RI-TRP-RE2B-30 offers lower cost and higher reliability for static ID use |
| EM4102 (from EM Microelectronic) | 64-bit read-only; 125 kHz operation; proprietary protocol; epoxy package instead of glass | Limited to legacy 125 kHz readers; less robust in high-moisture or chemically aggressive environments | Choose EM4102 only for backward compatibility with existing 125 kHz infrastructure; RI-TRP-RE2B-30 provides superior environmental resilience and global ISO standard alignment |
Compared with RI-TRP-WE2B-30 and EM4102, the RI-TRP-RE2B-30 delivers optimal balance of ISO compliance, glass-based durability, and zero-power operation for fixed-ID deployments-making it preferred for long-lifecycle industrial tagging where memory immutability and environmental hardness are primary requirements.

FAQ
Is RI-TRP-RE2B-30 still in production?
No, RI-TRP-RE2B-30 is marked as OBSOLETE by Texas Instruments per the 2016 Packaging Addendum. However, Aetrix Electronics maintains legacy inventory and supports continuity programs for customers dependent on this part in deployed systems.
What is the maximum reading distance for RI-TRP-RE2B-30?
The typical reading range for RI-TRP-RE2B-30 is ≤100 cm, but actual performance depends on reader antenna design, local RF regulations, and environmental factors such as nearby metallic objects or moisture. The transponder itself does not limit range-it responds only within the reader's usable magnetic field.
Can RI-TRP-RE2B-30 be programmed after manufacturing?
No, RI-TRP-RE2B-30 is a read-only device with factory-programmed 64-bit memory. It lacks write circuitry and cannot be reprogrammed in the field or during system integration. For programmable alternatives, consider RI-TRP-WE2B-30.
Does RI-TRP-RE2B-30 require a battery or external power source?
No, RI-TRP-RE2B-30 is fully passive and derives all operating energy from the reader's 134.2 kHz magnetic field. This eliminates battery replacement, leakage risk, and lifetime constraints-critical for sealed or inaccessible installations.
What environmental protections does RI-TRP-RE2B-30 offer?
RI-TRP-RE2B-30 features hermetic glass sealing (Protection Class: hermetically sealed), enabling operation from –25°C to +70°C and resistance to moisture, dust, chemicals, and mechanical shock per IEC 68-2-27 and IEC 68-2-6 standards-ideal for outdoor and industrial deployments.
