MRF150 RF MOSFET Equivalent & Substitute Parts

Part Overview

The MRF150 is an N-Channel RF MOSFET manufactured by MACOM Technology Solutions, designed for RF amplification applications operating across the 30MHz to 150MHz frequency range. This active product delivers 150W output power with a gain range of 8dB to 17dB, making it suitable for medium-power RF transmission and amplification circuits. The device operates at 50V test voltage with a 250mA test current rating and is housed in a 211-11 Style 2 package.

Equivalent and substitute parts are identified to provide design flexibility, support supply chain continuity, and accommodate specific packaging or inventory requirements while maintaining functional compatibility within the specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MRF150 are identified based on strict alignment with the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Technology: N-Channel MOSFET
• Frequency capability: Minimum 150MHz operation
• Power output: 150W
• Test voltage: 50V
• Test current: 250mA
• Product status: Active
• Compliance: ROHS3 Compliant

The VRF150 manufactured by Microchip Technology meets these core substitution requirements. While package format differs (M174 versus 211-11 Style 2), the electrical specifications align within the defined operating parameters. Rated voltage differs (170V versus 125V), representing an increased voltage margin in the substitute part.

Parameter Comparison

Engineering Selection Recommendations

MRF150 (MACOM Technology Solutions)

Select the MRF150 when the 211-11 Style 2 package format is required by circuit board layout specifications or when MACOM device qualification is mandated by design standards. The MRF150 maintains active product status with full ROHS3 compliance and unlimited moisture sensitivity rating, ensuring long-term supply availability and environmental regulatory adherence.

VRF150 (Microchip Technology)

The VRF150 serves as an electrical equivalent when package substitution is acceptable and M174 format compatibility exists in the target application. The VRF150 offers a higher rated voltage (170V versus 125V), providing increased voltage margin for circuit protection. Both devices maintain active status, ROHS3 compliance, and unlimited MSL rating. The VRF150 includes REACH Unaffected status, providing additional regulatory documentation.

Both parts are classified under ECCN EAR99 and carry appropriate HTSUS codes for international trade compliance.

Frequently Asked Questions (FAQ)

Q: Can the VRF150 directly replace the MRF150 in existing circuit designs?

A: Electrical substitution is supported based on matching technology (N-Channel MOSFET), frequency capability (150MHz), power output (150W), and test parameters (50V, 250mA). Package format differs (M174 versus 211-11 Style 2), requiring physical layout verification and PCB footprint compatibility assessment.

Q: What are the key differences between MRF150 and VRF150?

A: The primary differences are manufacturer (MACOM versus Microchip), package format (211-11 Style 2 versus M174), and rated voltage (125V versus 170V). Electrical performance parameters including frequency range, gain, power output, and test conditions align within specified tolerances.

Q: Are both parts RoHS compliant?

A: Yes. Both the MRF150 and VRF150 are ROHS3 Compliant with MSL rating of 1 (Unlimited), meeting environmental and moisture sensitivity requirements for industrial and commercial RF applications.

Q: What is the frequency operating range for each part?

A: The MRF150 operates across 30MHz to 150MHz. The VRF150 specification indicates 150MHz operation. Applications requiring operation below 150MHz should confirm VRF150 performance through detailed device characterization data.

Q: How do the gain specifications compare?

A: The MRF150 provides a gain range of 8dB to 17dB across its frequency band. The VRF150 specifies 11dB gain. Circuit designs dependent on the full 8dB to 17dB range should reference detailed gain versus frequency curves for the VRF150 to confirm suitability.

Q: What inventory status applies to these parts?

A: The MRF150 maintains 1,658 pieces in new original stock. The VRF150 maintains 33,300 pieces in new original stock, providing enhanced supply availability for high-volume production requirements.
