Key Parameters

Substitute Part Grouping Explanation

Substitution of the MMRF1009HR5 is determined by the following critical parameters:

Technology Match: Both the main part and substitute must utilize LDMOS technology for RF applications.

Frequency Compatibility: Operating frequency must align with the 1.03 GHz specification or operate within a compatible frequency band.

Voltage Specifications: Test voltage (50V) and rated voltage (110V) establish the electrical operating envelope.

Power Output Capability: The substitute must deliver equivalent or greater power output (500W baseline).

Gain Performance: Gain specification (19.7 dB) defines RF amplification characteristics.

Package and Mounting: Physical form factor and chassis mount configuration must be compatible with the original design.

Compliance Requirements: RoHS3 compliance and REACH unaffected status must be maintained.

The AFV10700HR5 qualifies as a substitute based on matching technology, voltage class, frequency band, mounting type, and regulatory compliance.

Power Performance: The AFV10700HR5 delivers 770W output power, exceeding the 500W specification of the original part, providing enhanced performance margin.

Mounting Configuration: Both parts utilize chassis mount configuration, maintaining mechanical compatibility with existing PCB layouts and thermal management systems.

Frequently Asked Questions (FAQ)

Q: Can the AFV10700HR5 directly replace the MMRF1009HR5 in existing designs?

A: The AFV10700HR5 is electrically and mechanically compatible based on matching technology (LDMOS), voltage class (50V test), frequency band (1.03 GHz), and mounting type (chassis mount). However, package differences exist: MMRF1009HR5 uses SOT-957A while AFV10700HR5 uses NI-780-4. PCB layout verification is required.

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

A: The AFV10700HR5 provides higher power output (770W versus 500W), operates across a wider frequency range (1.03-1.09 GHz versus 1.03 GHz), and maintains active product status. Test current is lower (100 mA versus 200 mA), and rated voltage is slightly lower (105V versus 110V).

Q: Why is the MMRF1009HR5 obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. The AFV10700HR5 represents the current active equivalent offering from NXP USA Inc. for this RF MOSFET application class.

Q: Are there compliance concerns with substitution?

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

Q: What packaging considerations apply?

A: The original MMRF1009HR5 uses SOT-957A (NI-780H-2L) packaging, while the substitute AFV10700HR5 uses NI-780-4 packaging. Physical dimensions and pin configurations differ. PCB redesign may be necessary to accommodate the different package form factor.

Q: Is the gain difference significant?

A: The AFV10700HR5 provides 19.2 dB gain compared to 19.7 dB for the MMRF1009HR5, representing a 0.5 dB difference. This falls within typical RF amplifier design tolerances.
