Key Parameters

Substitute Part Grouping Explanation

The TRF372017IRGZT from Texas Instruments qualifies as a functional substitute based on the following substitution criteria:

Core Functional Alignment:

• Both components perform upconverter functionality
• Both are active products with current manufacturing status
• Both support RF modulation across overlapping frequency bands

Frequency Coverage: The TRF372017IRGZT operates across 300MHz to 4.8GHz, which encompasses the SDM0102LC1CDC operating range of 1GHz to 2GHz. This extended frequency coverage allows the substitute to function within the original part's specified test frequency window.

Performance Parameters:

• TRF372017IRGZT P1dB: 12dBm (exceeds SDM0102LC1CDC at 5dBm)
• TRF372017IRGZT Output Power: 3dBm
• TRF372017IRGZT Noise Floor: -153dBm/Hz

Compliance & Regulatory: Both parts maintain REACH Unaffected status, ensuring equivalent environmental compliance.

Key Limitation: Package form factor differs significantly. The SDM0102LC1CDC is a module with SMA connectors, while the TRF372017IRGZT is a 48-VFQFN surface mount IC requiring PCB integration and external RF circuitry.

Parameter Comparison

Engineering Selection Recommendations

SDM0102LC1CDC Selection Criteria:

• Applications requiring integrated module form factor with SMA connectors
• Direct RF interface without additional PCB integration
• Designs constrained to 1GHz to 2GHz frequency band

• Systems requiring higher P1dB performance (12dBm vs 5dBm)
• PCB designs with available space for 48-VFQFN package footprint
• Applications utilizing dual supply voltage options (3V to 3.6V or 4.5V to 5.5V)

Both parts maintain active product status and REACH compliance, ensuring long-term availability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the TRF372017IRGZT directly replace the SDM0102LC1CDC in existing designs?

A: Direct replacement is not possible due to fundamental package differences. The SDM0102LC1CDC is a module with SMA connectors providing integrated RF interfaces, while the TRF372017IRGZT is a 48-VFQFN IC requiring PCB layout, external matching networks, and RF connector integration. Design modification is required.

Q: What frequency overlap exists between these parts?

A: The SDM0102LC1CDC operates at 1GHz to 2GHz. The TRF372017IRGZT covers 300MHz to 4.8GHz, providing complete coverage of the original part's frequency range with extended capability above and below.

Q: How do the performance specifications compare?

A: The TRF372017IRGZT provides superior P1dB performance at 12dBm compared to the SDM0102LC1CDC at 5dBm. The TRF372017IRGZT also specifies output power (3dBm) and noise floor (-153dBm/Hz), parameters not provided for the SDM0102LC1CDC.

Q: What are the supply voltage requirements for each part?

A: The SDM0102LC1CDC supply voltage is not specified in available documentation. The TRF372017IRGZT requires either 3V to 3.6V or 4.5V to 5.5V with 200mA supply current.

Q: Are both parts compliant with environmental regulations?

A: Yes. Both the SDM0102LC1CDC and TRF372017IRGZT maintain REACH Unaffected status. The TRF372017IRGZT additionally carries ROHS3 compliance certification.

Q: What packaging considerations apply to substitution?

A: The SDM0102LC1CDC module packaging with SMA connectors is suitable for direct system integration. The TRF372017IRGZT 48-VFQFN package requires surface mount assembly, PCB design integration, and external RF circuitry implementation.
