MMG20241HT1 Equivalent & Substitute Parts

Part Overview

The MMG20241HT1 is an RF amplifier IC manufactured by NXP Semiconductors, designed for general-purpose applications across the 450MHz to 3.8GHz frequency range. This surface-mount device in SOT-89A packaging delivers 17.8dB gain with a noise figure of 2.1dB at a test frequency of 2.655GHz. The part is currently in active production status with RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts may be required due to inventory constraints, regional availability, or specific application requirements within the allowable electrical and mechanical parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MMG20241HT1 is determined by the following critical parameters:

Package Compatibility: All substitute parts must use SOT-89A (TO-243AA) surface-mount packaging to ensure mechanical and thermal compatibility with existing PCB layouts.

Supply Voltage: Substitute parts must operate at 5V supply voltage to maintain compatibility with existing power distribution networks.

Frequency Coverage: Substitute parts must support operation within or encompassing the 450MHz to 3.8GHz frequency range of the primary application.

RF Type Classification: All parts must be classified as general-purpose RF amplifiers to ensure functional equivalence.

Compliance Requirements: Substitute parts must maintain RoHS3 compliance and REACH unaffected status to satisfy regulatory requirements.

The identified substitute parts (HMC453ST89E and HMC453ST89ETR) meet these core substitution criteria, though with differing electrical performance characteristics within the allowable parameter space.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (MMG20241HT1): Recommended for applications requiring extended frequency coverage to 3.8GHz, lower noise figure performance (2.1dB), and reduced supply current consumption (78mA). Active production status and full RoHS3/REACH compliance support long-term availability and regulatory requirements.

Substitute Parts (HMC453ST89E / HMC453ST89ETR): Both substitute parts maintain active production status and full regulatory compliance (RoHS3, REACH unaffected). These parts are electrically equivalent to each other, differing only in packaging format (Strip vs. Bulk). Selection between these substitutes should be based on procurement packaging requirements and inventory availability. Note that frequency coverage is limited to 400MHz ~ 2.2GHz, and electrical performance characteristics (gain, noise figure, supply current) differ significantly from the primary part.

Compliance Basis: All three parts carry identical ECCN (EAR99) and HTSUS (8542.33.0001) classifications, confirming regulatory equivalence for export and tariff purposes.

Frequently Asked Questions (FAQ)

Q: Can HMC453ST89E or HMC453ST89ETR be used as direct drop-in replacements for MMG20241HT1?

A: Both substitute parts use identical SOT-89A (TO-243AA) surface-mount packaging and 5V supply voltage, enabling mechanical and electrical compatibility at the board level. However, the reduced frequency coverage (400MHz ~ 2.2GHz vs. 450MHz ~ 3.8GHz) and different electrical performance characteristics require circuit-level evaluation for specific applications.

Q: What is the difference between HMC453ST89E and HMC453ST89ETR?

A: Both parts are manufactured by the same source (Hittite technology, now part of Analog Devices) and share identical electrical specifications. The primary difference is packaging format: HMC453ST89E is supplied in Strip packaging, while HMC453ST89ETR is supplied in Bulk packaging. Selection depends on procurement volume and handling requirements.

Q: Are all three parts RoHS3 compliant?

A: Yes. MMG20241HT1, HMC453ST89E, and HMC453ST89ETR all carry RoHS3 compliance certification and REACH unaffected status, satisfying current regulatory requirements for electronic component procurement.

Q: What are the key electrical differences between the primary part and substitutes?

A: The MMG20241HT1 provides higher gain (17.8dB vs. 7.5dB), lower noise figure (2.1dB vs. 6.5dB), and significantly lower supply current (78mA vs. 725mA). The substitute parts offer higher output power capability (P1dB of 32.5dBm vs. 23.9dBm). Frequency coverage differs: MMG20241HT1 extends to 3.8GHz, while substitutes are limited to 2.2GHz.

Q: Can substitutes be used in applications requiring operation above 2.2GHz?

A: No. HMC453ST89E and HMC453ST89ETR are specified only to 2.2GHz. Applications requiring operation at 2.655GHz or higher frequencies must use MMG20241HT1 or identify alternative parts with extended frequency specifications.
