MGA-425P8-TR2 Equivalent & Substitute Parts

Part Overview

The MGA-425P8-TR2 is an RF amplifier IC designed for ISM and 802.11a/WiFi applications across the 2GHz to 10GHz frequency range. Manufactured by Broadcom Limited, this component operates at 3.3V supply voltage with a noise figure of 1.7dB and gain specifications between 14.5dB and 17.5dB. The device is packaged in an 8-LPCC (2x2) surface mount configuration with an exposed pad.

This part has reached obsolete status, making substitute component identification essential for ongoing system support, design updates, and procurement continuity. Alternative components must maintain functional equivalence within the specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute component identification for the MGA-425P8-TR2 is based on the following critical parameters:

Frequency coverage must encompass or overlap the 2GHz to 10GHz operating range. The substitute part HMC466LP4ETR operates at 6.1GHz to 6.72GHz, which falls within the upper portion of the original part's frequency specification, making it suitable for applications operating in this band.

Gain and noise figure characteristics must support the RF amplification function. The MGA-425P8-TR2 delivers 14.5dB to 17.5dB gain with 1.7dB noise figure at 5.25GHz test frequency. Substitute components must provide comparable RF performance metrics for the intended application frequency.

Supply voltage compatibility is mandatory. The MGA-425P8-TR2 operates at 3.3V. Substitute parts must support the same supply voltage or be compatible with existing power distribution architecture.

Mounting type and package form factor must be surface mount compatible. The original 8-LPCC (2x2) package requires substitutes with equivalent or compatible footprints for PCB integration.

Compliance certifications including REACH status and ECCN classification must align with regulatory and export requirements. Both the original and substitute parts maintain REACH Unaffected status and EAR99 classification.

Parameter Comparison

Engineering Selection Recommendations

The HMC466LP4ETR is identified as a substitute component based on active product status and regulatory compliance alignment. This part is currently in active production by Analog Devices Inc., ensuring long-term availability and supply chain continuity compared to the obsolete MGA-425P8-TR2.

Both components maintain identical REACH Unaffected status and EAR99 ECCN classification, confirming regulatory compatibility for applications requiring these certifications.

The frequency range of the HMC466LP4ETR (6.1GHz to 6.72GHz) overlaps with the upper operating band of the MGA-425P8-TR2 (2GHz to 10GHz). Applications operating within the 6.1GHz to 6.72GHz band can utilize this substitute without frequency-related constraints.

Package form factor differs between the original 8-LPCC (2x2) and substitute 24-QFN (4x4) configurations. PCB layout redesign is required to accommodate the larger footprint and increased pin count of the HMC466LP4ETR.

Both components feature surface mount technology and MSL 1 (Unlimited) moisture sensitivity rating, supporting standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the HMC466LP4ETR directly replace the MGA-425P8-TR2 without PCB modifications?

A: No. The HMC466LP4ETR uses a 24-QFN (4x4) package compared to the original 8-LPCC (2x2) package. PCB layout redesign is required to accommodate the different footprint and pin configuration.

Q: What frequency bands support substitution with the HMC466LP4ETR?

A: The HMC466LP4ETR operates at 6.1GHz to 6.72GHz. Applications requiring amplification within this frequency range can utilize this substitute. Applications requiring coverage below 6.1GHz or above 6.72GHz require alternative components.

Q: Are there compliance differences between the MGA-425P8-TR2 and HMC466LP4ETR?

A: Both components maintain REACH Unaffected status and EAR99 ECCN classification. No compliance barriers exist for substitution in regulated applications.

Q: What is the impact of the package size difference?

A: The HMC466LP4ETR features a larger 24-pin QFN package versus the 8-pin LPCC original. This requires PCB redesign, increased board space allocation, and updated thermal management considerations.

Q: Is the HMC466LP4ETR suitable for ISM and 802.11a/WiFi applications?

A: The HMC466LP4ETR is specified for VSAT and buffer amplifier functions. Application suitability depends on specific circuit requirements, impedance matching, and frequency band alignment within the 6.1GHz to 6.72GHz range.

Q: What is the supply voltage requirement for the HMC466LP4ETR?

A: Refer to the HMC466LP4ETR datasheet for specific supply voltage specifications. Voltage compatibility must be verified before implementation.
