MMRF1007HR5 Equivalent & Substitute Parts

Part Overview

The MMRF1007HR5 is an RF MOSFET LDMOS transistor manufactured by NXP USA Inc., designed for high-frequency RF applications. This device operates at 1.03 GHz with 20 dB gain and delivers 1000 W output power at 50 V test voltage. The part is classified as obsolete, necessitating identification of active equivalent components for continued system support and new designs. Substitute parts must maintain electrical performance within the specified parameter ranges while offering current manufacturing availability.

Engineering Selection Recommendations

The AFV121KHR5 serves as the manufacturer-recommended substitute for the obsolete MMRF1007HR5. Selection of this substitute is supported by the following factors:

Product Status: The MMRF1007HR5 is classified as obsolete, making long-term procurement and supply chain continuity problematic. The AFV121KHR5 maintains active product status with current manufacturing support from NXP USA Inc.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring compatibility with current environmental and regulatory requirements.

Electrical Performance: The AFV121KHR5 operates within the specified frequency range (960 MHz – 1.22 GHz encompasses the 1.03 GHz operating point), maintains 1000 W output power, and operates at 50 V test voltage. Gain variation of 0.4 dB and current test variation of 50 mA fall within acceptable engineering tolerances for RF MOSFET applications.

Manufacturing Continuity: Current inventory availability of 654 pieces ensures supply chain reliability for both new designs and legacy system support.

Frequently Asked Questions (FAQ)

Q: Can AFV121KHR5 directly replace MMRF1007HR5 in existing designs?

A: The AFV121KHR5 is electrically compatible within specified parameter ranges. However, package designation differences (NI-1230-4H case vs. SOT-979A) require verification of mechanical fit and PCB layout compatibility. Both parts share the same supplier device package designation (NI-1230-4H), indicating functional equivalence.

Q: What is the significance of the frequency range difference (1.03 GHz vs. 960 MHz – 1.22 GHz)?

A: The substitute part operates across a broader frequency range that encompasses the original 1.03 GHz specification. This wider bandwidth provides operational flexibility while maintaining performance at the original design frequency.

Q: How do the gain specifications compare?

A: The MMRF1007HR5 specifies 20 dB gain, while the AFV121KHR5 specifies 19.6 dB gain. This 0.4 dB difference is within typical RF MOSFET manufacturing tolerances and does not constitute a functional limitation for most applications.

Q: Are there compliance or certification differences between these parts?

A: Both parts maintain identical RoHS3 compliance and REACH unaffected status. No compliance barriers exist for substitution.

Q: What is the impact of the current test rating difference (150 mA vs. 100 mA)?

A: The substitute part operates at lower test current while maintaining identical 1000 W output power specification. This indicates improved efficiency characteristics and does not represent a performance reduction.

Q: Is the AFV121KHR5 available in the same packaging format?

A: The AFV121KHR5 is available in Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging options, providing flexibility for both high-volume and component-level procurement.
