RI-TRP-RR2B-30 Equivalent & Substitute Parts

Part Overview

The RI-TRP-RR2B-30 is an RFID tag operating at 134.2kHz with read/write memory capability, designed to ISO 11785 standards and housed in a glass-encapsulated form factor measuring 3.85mm diameter by 31.20mm length. This component is classified as obsolete, necessitating identification of active equivalent parts to maintain supply chain continuity for applications requiring RFID identification at this frequency and physical specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RI-TRP-RR2B-30 is determined by the following critical parameters:

• Frequency: 134.2kHz (mandatory match)
• Physical form factor: 3.85mm diameter x 31.20mm length glass encapsulation (mandatory match)
• Standards compliance: ISO 11785 (mandatory match)
• Manufacturer: Texas Instruments (preferred for consistency)
• RoHS and REACH compliance status (regulatory requirement match)

The identified substitute part TRPGR30ATGB maintains frequency, physical dimensions, and standards compliance. However, the memory type differs: the substitute operates as read-only memory rather than read/write. This distinction represents a functional limitation that must be evaluated against application requirements.

Parameter Comparison

Engineering Selection Recommendations

The TRPGR30ATGB serves as an active substitute for the obsolete RI-TRP-RR2B-30 based on matching frequency, physical dimensions, and regulatory compliance. Both components maintain ROHS3 and REACH compliance status, ensuring regulatory alignment.

The primary consideration for component selection is the memory functionality difference. Applications requiring write capability to the RFID tag cannot use the read-only substitute without system redesign. Applications limited to read-only operations can transition to TRPGR30ATGB without functional impact. The substitute's active product status and specified operating temperature range (-25°C ~ 70°C) provide improved supply chain availability and defined thermal performance parameters compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can TRPGR30ATGB directly replace RI-TRP-RR2B-30 in all applications?

A: Direct replacement is possible only in applications that do not require write capability to the RFID tag memory. The substitute operates as read-only memory, whereas the main part supports read/write operations. System requirements must be evaluated to determine if read-only functionality is acceptable.

Q: Are the physical dimensions identical between the main part and substitute?

A: Yes. Both components measure 3.85mm diameter by 31.20mm length in glass-encapsulated form factor, ensuring mechanical compatibility in existing installations.

Q: What is the frequency compatibility between these parts?

A: Both components operate at 134.2kHz and comply with ISO 11785 standards, ensuring frequency and protocol compatibility.

Q: Does the substitute offer improved specifications?

A: The TRPGR30ATGB provides a defined operating temperature range of -25°C ~ 70°C, whereas the main part does not specify operating temperature limits. The substitute is also available in active production status with Tape & Reel packaging, improving supply chain accessibility.

Q: Are regulatory compliance certifications maintained?

A: Yes. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory requirements are met in either configuration.
