MRF316 Equivalent & Substitute Parts Reference

Part Overview

The MRF316 is an RF Transistor NPN rated at 35V, 9A, and 80W maximum power dissipation in a chassis mount 316-01 package. Manufactured by MACOM Technology Solutions, this component is classified as Active and RoHS3 Compliant. The MRF316 serves applications requiring high-power RF amplification in the VHF/UHF frequency range with moderate gain characteristics (13dB). Substitute parts become necessary when chassis mount packaging is incompatible with application requirements, when surface mount integration is preferred, or when inventory constraints necessitate alternative sourcing from qualified manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MRF316 is determined by the following critical parameters: transistor type (NPN), voltage rating capability, current handling capacity, power dissipation rating, and mounting compatibility. The MRF316 operates as a high-power RF amplifier with 35V breakdown voltage and 9A maximum collector current. Substitute parts listed below represent surface mount alternatives from Infineon Technologies that maintain NPN transistor topology and active product status. These substitutes operate at reduced voltage ratings (5V to 9V) and reduced current levels (20mA to 80mA), reflecting their application in higher-frequency, lower-power RF circuits. Substitution is valid only when application requirements permit reduced voltage and current specifications while maintaining NPN configuration and active manufacturing status.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and RoHS3 compliance, ensuring long-term availability and regulatory conformance. The MRF316 is a chassis mount component designed for high-power applications; direct substitution requires application redesign to accommodate surface mount packages (SOT-723, SOT-343, or 4-TSFP). Selection among substitute parts depends on specific application voltage and current requirements. BFR340FH6327XTSA1 operates at 9V maximum, closest to the MRF316 voltage class but with significantly reduced current capacity (20mA). BFP420H6801XTSA1 and BFP540FESDH6327XTSA1 operate at 5V maximum with higher frequency capability (25GHz and 30GHz respectively) but further reduced voltage ratings. All substitutes are manufactured by Infineon Technologies with confirmed inventory availability and identical MSL ratings to the primary part.

Frequently Asked Questions (FAQ)

Q: Can BFR340FH6327XTSA1, BFP420H6801XTSA1, or BFP540FESDH6327XTSA1 directly replace MRF316 in existing designs?

A: No. The MRF316 is a chassis mount component; all listed substitutes are surface mount devices. PCB layout and mounting infrastructure must be redesigned. Additionally, voltage and current ratings differ significantly, requiring circuit analysis to confirm compatibility with application specifications.

Q: What are the primary differences between the three substitute parts?

A: BFR340FH6327XTSA1 operates at 9V maximum with 14GHz transition frequency and 75mW power rating in SOT-723 package. BFP420H6801XTSA1 operates at 5V maximum with 25GHz transition frequency and 160mW power rating in SOT-343 package. BFP540FESDH6327XTSA1 operates at 5V maximum with 30GHz transition frequency and 250mW power rating in 4-TSFP package. Selection depends on required frequency response and power dissipation.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. BFR340FH6327XTSA1, BFP420H6801XTSA1, and BFP540FESDH6327XTSA1 are all RoHS3 Compliant with MSL rating of 1 (Unlimited), matching the MRF316 environmental specifications.

Q: What is the inventory status of substitute parts?

A: BFR340FH6327XTSA1 has 6464 pieces in stock. BFP420H6801XTSA1 has 9559 pieces in stock. BFP540FESDH6327XTSA1 has 3259 pieces in stock. All parts are listed as New Original.

Q: Which substitute part has the highest power rating?

A: BFP540FESDH6327XTSA1 with 250mW maximum power dissipation, followed by BFP420H6801XTSA1 at 160mW, and BFR340FH6327XTSA1 at 75mW. The MRF316 operates at 80W, significantly higher than all substitutes.
