PE43602MLI RF Attenuator Equivalent & Substitute Parts

Part Overview

The PE43602MLI is an RF attenuator manufactured by pSemi, designed for applications requiring fixed 31.5dB attenuation across the 9 kHz to 5 GHz frequency range with 50 Ohm impedance. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and new design implementations. The PE43602MLI operates within the UltraCMOS® and HaRP™ series platforms and is packaged in a 24-VFQFN Exposed Pad configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PE43602MLI is determined by the following critical parameters:

• Attenuation Capability: The substitute must provide the required 31.5dB attenuation value or operate within a range that includes 31.5dB
• Frequency Range: The substitute must cover the minimum 9 kHz to 5 GHz operating band
• Impedance: The substitute must maintain 50 Ohm characteristic impedance
• Package Compatibility: The substitute must use the 24-VFQFN Exposed Pad package to ensure PCB layout and thermal management compatibility
• Moisture Sensitivity: The substitute must meet or exceed MSL 1 classification

The PE43711B-Z qualifies as a substitute based on these parameters, offering programmable attenuation from 0dB to 31.75dB, extended frequency coverage to 6 GHz, and identical package specifications.

Engineering Selection Recommendations

The PE43711B-Z is the designated substitute for the obsolete PE43602MLI. Selection of this substitute is supported by the following factors:

• Active Product Status: The PE43711B-Z maintains active manufacturing and distribution status, ensuring long-term availability and supply chain continuity
• Compliance Certifications: Both parts share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications, maintaining regulatory consistency
• RoHS3 Compliance: The PE43711B-Z is RoHS3 compliant and REACH unaffected, meeting current environmental standards
• Enhanced Specifications: The substitute provides extended frequency coverage (9 kHz to 6 GHz) and programmable attenuation capability (0dB to 31.75dB), offering design flexibility beyond the fixed 31.5dB specification of the original part
• Identical Package: The 24-VFQFN Exposed Pad package ensures direct PCB layout compatibility without redesign requirements

Frequently Asked Questions (FAQ)

Q: Can the PE43711B-Z directly replace the PE43602MLI in existing designs?

A: Yes. Both components share identical package specifications (24-VFQFN Exposed Pad), impedance (50 Ohms), frequency range coverage (PE43711B-Z extends to 6 GHz), and moisture sensitivity classification. The PE43711B-Z can be configured to provide the required 31.5dB attenuation through its programmable range of 0dB to 31.75dB.

Q: What is the primary advantage of using the PE43711B-Z over the PE43602MLI?

A: The PE43711B-Z offers programmable attenuation control, allowing dynamic adjustment across its 0dB to 31.75dB range, whereas the PE43602MLI provides fixed 31.5dB attenuation. Additionally, the PE43711B-Z maintains active product status with guaranteed availability, addressing the obsolescence of the PE43602MLI.

Q: Are there any frequency range differences between these parts?

A: The PE43602MLI operates from 9 kHz to 5 GHz, while the PE43711B-Z extends coverage to 6 GHz. This extended range in the substitute provides additional operational bandwidth without compromising performance in the original 5 GHz specification window.

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

A: Yes. Both the PE43602MLI and PE43711B-Z share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications. The PE43711B-Z additionally maintains RoHS3 compliance and REACH unaffected status, meeting current environmental regulations.

Q: What packaging options are available for the PE43711B-Z?

A: The PE43711B-Z is supplied in Cut Tape (CT) and Digi-Reel® packaging formats, providing flexibility for both prototype and production volume requirements.
