Key Parameters

Substitute Part Grouping Explanation

Substitution of the ATF-36163-TR2G is determined by the following critical parameters:

Technology Match: Both the main part and substitute must utilize pHEMT FET technology to maintain equivalent RF performance characteristics.

Frequency Compatibility: Operating frequency must support the intended application band. The ATF-36163-TR2G operates at 4GHz; substitute parts must demonstrate RF performance within compatible frequency ranges.

Gain and Noise Figure: Gain (15.8dB) and noise figure (0.6dB) define amplification capability and signal quality. Substitute parts must provide comparable performance metrics.

Voltage and Current Ratings: Test voltage (2V), rated voltage (3V), test current (15mA), and current rating (40mA) establish operating point compatibility. Substitute parts must accommodate these electrical requirements.

Package Compatibility: The SOT-363 package defines physical footprint and pin configuration. Substitute parts in alternative packages (SC-70-4, SC-82A, SOT-343) require PCB layout modification.

Product Status and Compliance: Active product status ensures ongoing availability and support. REACH and RoHS compliance certifications confirm regulatory alignment.

Parameter Comparison

Engineering Selection Recommendations

SKY65050-372LF Substitution Criteria:

The SKY65050-372LF from Skyworks Solutions Inc. is identified as the manufacturer-recommended substitute for the obsolete ATF-36163-TR2G. Both devices employ pHEMT FET technology and share comparable gain characteristics (15.8dB vs. 15.5dB). The SKY65050-372LF maintains MSL 1 moisture sensitivity rating and REACH compliance status, ensuring equivalent environmental and regulatory handling requirements.

Electrical Performance Considerations:

The SKY65050-372LF operates at 2.4GHz, which differs from the ATF-36163-TR2G 4GHz specification. This frequency difference reflects the substitute's design optimization for 2.4GHz ISM band applications. The substitute provides superior noise figure (0.4dB vs. 0.6dB) and higher output power (10.5dBm vs. 5dBm), with increased voltage rating (6V vs. 3V) and current capacity (55mA vs. 40mA).

Package and Layout Impact:

The SKY65050-372LF uses SC-70-4 (SOT-343) packaging, which differs from the ATF-36163-TR2G SOT-363 footprint. PCB layout modification is required for physical implementation. Both packages maintain surface mount configuration and MSL 1 classification.

Product Availability:

The ATF-36163-TR2G is obsolete with limited remaining inventory (767 pcs). The SKY65050-372LF is active product with substantial inventory availability (47571 pcs), ensuring long-term procurement continuity and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the SKY65050-372LF directly replace the ATF-36163-TR2G without circuit modification?

A: Direct pin-for-pin replacement is not possible due to package differences (SOT-363 vs. SC-70-4). PCB layout redesign is required. Circuit performance may require tuning adjustments due to frequency differences (4GHz vs. 2.4GHz) and electrical parameter variations.

Q: What are the key electrical differences between these parts?

A: The SKY65050-372LF operates at 2.4GHz compared to the ATF-36163-TR2G at 4GHz. The substitute provides lower noise figure (0.4dB vs. 0.6dB), higher output power (10.5dBm vs. 5dBm), and higher voltage rating (6V vs. 3V). Gain values are comparable (15.5dB vs. 15.8dB).

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the ATF-36163-TR2G and SKY65050-372LF maintain REACH Unaffected status and MSL 1 moisture sensitivity classification. The SKY65050-372LF additionally carries RoHS3 compliance certification.

Q: What is the impact of frequency difference on circuit design?

A: The 4GHz to 2.4GHz frequency shift requires impedance matching network redesign and PCB layout optimization for the new operating frequency. Application suitability depends on whether the target circuit operates within the 2.4GHz band.

Q: Is the SKY65050-372LF suitable for 4GHz applications?

A: The SKY65050-372LF is optimized for 2.4GHz operation. Use in 4GHz applications requires application-specific evaluation and is not recommended without detailed RF performance analysis.

Q: What packaging considerations apply to the substitution?

A: The ATF-36163-TR2G uses 6-pin SOT-363 packaging; the SKY65050-372LF uses 4-pin SC-70-4 packaging. Pin count and footprint differences necessitate complete PCB redesign. Both maintain surface mount configuration and identical moisture sensitivity levels.
