Key Parameters

Substitute Part Grouping Explanation

Substitute parts are grouped strictly by matching the following key parameters: technology (LDMOS), test voltage (28 V), output power (24W), rated voltage (65 V), RoHS compliance, and similar frequency and gain characteristics. Mechanical compatibility is considered by referencing the package and mounting specifications. Only parts matching these parameters are listed as suitable substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both the MRF7S19080HSR3 and its substitute, AFT20P140-4WNR3, are listed as obsolete components. Both are ROHS3 compliant and REACH unaffected, with their respective MSL ratings provided. Selection between these options should be based strictly on compliance, product status, and the verified inventory and package compatibility.

Frequently Asked Questions (FAQ)

Q1: What are the key criteria for selecting substitute MOSFET transistors in RF applications?
A1: Selection is based strictly on matching technology (LDMOS), test and rated voltages, output power, frequency range, gain, and compliance status, as well as matching package and mounting style.

Q2: Is there full mechanical compatibility between MRF7S19080HSR3 and AFT20P140-4WNR3?
A2: The MRF7S19080HSR3 uses the NI-780S package for chassis mounting, while the AFT20P140-4WNR3 uses the OM-780-4L package for surface mounting. Package and mounting differences should be cross-checked in the application.

Q3: Are there differences in Moisture Sensitivity Level (MSL) between these parts?
A3: Yes. MRF7S19080HSR3 is rated MSL 1 (Unlimited), while AFT20P140-4WNR3 is rated MSL 3 (168 Hours).

Q4: Are both parts compliant with international environmental standards?
A4: Both parts are ROHS3 compliant and REACH unaffected according to the provided parameters.

Q5: Does the frequency range differ between these two parts?
A5: MRF7S19080HSR3 is rated for 1.99GHz, while AFT20P140-4WNR3 covers the range 1.88GHz ~ 1.91GHz. Frequency range should be matched according to application requirements.
