AOZ8020DI Equivalent & Substitute Parts

Part Overview

The AOZ8020DI is an RC (Pi) EMI filter featuring 2nd order low pass filtering with 8 channels, designed for data line protection in mobile device applications. This component provides 100 Ohm resistance per channel with 9pF capacitance and operates across -40°C to 85°C. The part is currently classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AOZ8020DI is determined by the following critical parameters:

• Filter topology and order (RC Pi, 2nd order low pass)
• Number of channels (8 channels)
• Resistance value per channel (100 Ohms)
• Package type and form factor (16-UFDFN Exposed Pad)
• Operating temperature range (-40°C to 85°C)
• ESD protection capability
• Regulatory compliance (ROHS3, REACH Unaffected)

The EMI5208MUTAG qualifies as a direct substitute based on matching filter architecture, channel count, resistance specification, package footprint, temperature range, and compliance certifications. The primary difference lies in capacitance value (7pF versus 9pF), which results in a higher cutoff frequency characteristic suitable for equivalent data line filtering applications.

Parameter Comparison

Engineering Selection Recommendations

The EMI5208MUTAG is the qualified substitute for the AOZ8020DI based on the following criteria:

• Identical filter architecture and channel configuration
• Matching 100 Ohm per-channel resistance specification
• Compatible 16-UFDFN Exposed Pad package with identical electrical footprint
• Equivalent operating temperature range
• Active product status with established supply chain availability
• Full ROHS3 compliance and REACH unaffected status
• Maintained ESD protection capability

The AOZ8020DI's obsolete status necessitates transition to the EMI5208MUTAG for new designs and ongoing procurement. The substitute maintains functional equivalence for data line filtering applications in mobile devices.

Frequently Asked Questions (FAQ)

Q: Can the EMI5208MUTAG directly replace the AOZ8020DI in existing designs?

A: Yes. Both components share identical package geometry (16-UFDFN Exposed Pad), channel count (8), and per-channel resistance (100 Ohms). The footprint and electrical interface are compatible for direct PCB substitution.

Q: What is the significance of the capacitance difference (9pF vs 7pF)?

A: The capacitance value affects the filter's frequency response characteristics. The EMI5208MUTAG's 7pF capacitance produces a higher cutoff frequency compared to the AOZ8020DI's 9pF specification. Both maintain the 250MHz nominal cutoff frequency for data line filtering applications.

Q: Are there temperature or compliance concerns with substitution?

A: No. Both components operate across -40°C to 85°C and maintain ROHS3 compliance with REACH unaffected status. Regulatory and thermal operating parameters are equivalent.

Q: What is the packaging difference between these parts?

A: The AOZ8020DI packaging format is not specified in available documentation. The EMI5208MUTAG is supplied in Tape & Reel (TR) format, which is standard for high-volume production environments.

Q: Is the EMI5208MUTAG suitable for mobile device data line applications?

A: Yes. The EMI5208MUTAG is specified for data line protection in mobile devices, matching the AOZ8020DI's intended application. The 8-channel configuration and ESD protection capability support this use case.
