Product details
Overview
RI-TRP-W9QL-20 from Texas Instruments is a 30 mm ISO 11784/11785-compliant LF RFID transponder operating at 134.2 kHz, supporting HDX half-duplex communication, 80-bit read/write memory, and IP67-rated POM housing. It delivers stable performance in vehicle identification, container tracking, and waste management systems where batteryless operation and non-metallic material penetration are required.
For engineers reviewing the RI-TRP-W9QL-20 datasheet, RI-TRP-W9QL-20 pinout, RI-TRP-W9QL-20 application, or RI-TRP-W9QL-20 equivalent, key selection considerations include its HDX modulation scheme, 30% programming range relative to reading range, 100,000-programming-cycle endurance, and operational temperature limit of –25°C to +70°C in harsh industrial environments.
Technical Context
This transponder uses Half-Duplex (HDX) communication with FSK modulation at 134.2 kHz (carrier) and 123.2 kHz (shift), enabling reliable bidirectional data exchange without an internal power source. Its patented tuning process ensures consistent coupling efficiency and immunity to electromagnetic interference across varying reader antenna configurations.
It implements a single-page 80-bit memory architecture-structured as 64 user-programmable bits plus a 16-bit CRC CCITT block check character-and complies fully with ISO/IEC 11784/11785 for global animal and asset identification interoperability.

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-W9QL-30 | Same functionality and specs, but packaged in tape-and-reel (250 pcs) instead of bulk (–20 suffix denotes obsolete bulk packaging) | Identical use cases; preferred for automated SMT assembly lines requiring reel-fed feeding | Select RI-TRP-W9QL-30 for new designs requiring volume procurement and consistent packaging format |
| RI-TRP-R9QL-30 | 64-bit read-only memory (vs. 80-bit read/write); same HDX, ISO compliance, and mechanical specs | Suitable only for static ID applications (e.g., animal ear tags), not for dynamic data logging or field updates | Choose RI-TRP-R9QL-30 when write capability is unnecessary and cost minimization is prioritized |
Compared with RI-TRP-W9QL-20, the RI-TRP-W9QL-30 offers identical electrical and mechanical performance with optimized packaging for production scalability, while the RI-TRP-R9QL-30 trades programmability for lower unit cost and simpler data management in fixed-ID deployments.

FAQ
What is the memory configuration of the RI-TRP-W9QL-20?
The RI-TRP-W9QL-20 features an 80-bit read/write memory organized as one page, with TI recommending allocation of 64 bits for user data and 16 bits for a CRC CCITT block check character to ensure data integrity during programming and read operations. This structure is implemented in hardware and cannot be reconfigured.
Is the RI-TRP-W9QL-20 compatible with standard ISO 11784/11785 readers?
Yes, the RI-TRP-W9QL-20 is fully compliant with ISO/IEC 11784 and 11785 standards for low-frequency RFID transponders. It uses HDX protocol and FSK modulation at 134.2 kHz, ensuring interoperability with certified readers deployed in animal identification, vehicle access, and logistics systems worldwide.
What does the "-20" suffix mean in RI-TRP-W9QL-20?
The "-20" suffix in RI-TRP-W9QL-20 indicates obsolete bulk packaging-TI discontinued this variant in favor of tape-and-reel formats like RI-TRP-W9QL-30. The "-20" part remains functionally identical to active variants but is no longer manufactured or stocked by TI; Aetrix Electronics provides traceable legacy supply for maintenance and repair.
Can the RI-TRP-W9QL-20 be embedded in metal environments?
No-the RI-TRP-W9QL-20 is explicitly insensitive to non-metallic materials only. Metal surfaces detune its LC resonator and block magnetic coupling; it must be mounted with a minimum air gap or dielectric spacer (e.g., plastic or rubber) between the transponder and any conductive surface to maintain reading range and reliability.
What is the typical programming time for the RI-TRP-W9QL-20?
The typical programming time for the RI-TRP-W9QL-20 is 309 ms per full 80-bit write operation, as specified in the official TI datasheet SCBS837. This duration reflects the HDX protocol overhead, CRC calculation, and verification sequence required to ensure data integrity in field-deployed conditions.
