Key Parameters

Substitute Part Grouping Explanation

Substitution of the MHT2000NR1 is based on the following critical parameters:

Operating frequency alignment at 2.45GHz ensures RF performance compatibility within the intended application band. Gain specification (30.5dB) establishes the amplification level required for signal processing. Supply voltage compatibility (26V ~ 32V range) and current consumption (195mA) determine power delivery requirements. Package type and mounting configuration affect physical integration into existing designs.

The identified substitute, AFIC31025GNR1, maintains the 2.45GHz operating frequency and demonstrates higher gain performance (34.5dB) with compatible supply voltage specification (32V). The transition from chassis mount TO-272-16 to surface mount TO-270-17 represents a packaging evolution while preserving functional RF characteristics. Both parts maintain ROHS3 compliance and identical MSL ratings, supporting regulatory and environmental requirements.

Parameter Comparison

Engineering Selection Recommendations

The AFIC31025GNR1 serves as the active substitute for the obsolete MHT2000NR1. Both parts are manufactured by NXP USA Inc. and maintain identical regulatory compliance certifications (ROHS3, REACH Unaffected). The substitute operates at the same 2.45GHz frequency with enhanced gain performance (34.5dB versus 30.5dB), supporting improved signal amplification in RF applications.

The primary design consideration involves package transition from chassis mount TO-272-16 to surface mount TO-270-17. This change requires PCB layout modification and assembly process adjustment but provides access to an active, supported component with current manufacturing availability. Supply voltage specification narrows from a 26V–32V range to a fixed 32V requirement; system power delivery must accommodate this specification.

Frequently Asked Questions (FAQ)

Q: Can AFIC31025GNR1 directly replace MHT2000NR1 without circuit modification?

A: Functional RF performance is compatible at 2.45GHz with equivalent supply voltage operation at 32V. However, the package transition from chassis mount TO-272-16 to surface mount TO-270-17 requires PCB layout redesign and assembly process changes. Mechanical mounting and electrical connection points differ between the two package types.

Q: What is the impact of the gain difference (30.5dB versus 34.5dB)?

A: The AFIC31025GNR1 provides 4dB higher gain. System designs must account for this increased amplification in signal chain calculations, potentially requiring adjustment of downstream components or feedback networks to maintain target output levels and prevent saturation.

Q: Are there supply current differences between the parts?

A: The MHT2000NR1 specifies 195mA supply current. The AFIC31025GNR1 supply current is not provided in the available data. Power delivery design should reference the MHT2000NR1 specification as a baseline until AFIC31025GNR1 current consumption is confirmed through manufacturer documentation.

Q: Do both parts meet the same environmental and regulatory standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry identical MSL ratings of 3 (168 Hours), supporting equivalent environmental and regulatory requirements.

Q: What is the availability status of each part?

A: MHT2000NR1 is classified as obsolete with 1159 units in stock. AFIC31025GNR1 is active with 779 units available in tape and reel packaging, ensuring ongoing supply for new designs and production requirements.
