Substitute Part Grouping Explanation

Substitution eligibility for the AOZ8010DTL is determined by the following critical parameters:

Filter Architecture: RC (Pi) topology with 2nd order configuration
Channel Count: 8 channels
Resistance Value: 100 Ohms per channel
Package Type: 16-UFDFN Exposed Pad form factor
Operating Temperature Range: -40°C ~ 85°C
ESD Protection: Integrated protection required
Surface Mount Compatibility: SMD mounting requirement

The EMIF08-1005M16 from STMicroelectronics meets these core substitution criteria. While the capacitance value differs (45 pF versus 28 pF), resulting in a higher cutoff frequency (100 MHz versus 90 MHz) and different attenuation characteristics, the fundamental electrical architecture, channel configuration, resistance value, package footprint, and operating specifications remain compatible for applications requiring RC (Pi) EMI filtering on data lines.

Engineering Selection Recommendations

The EMIF08-1005M16 is the active equivalent for the obsolete AOZ8010DTL. Both parts share identical filter topology, channel architecture, resistance specifications, and package form factor. The substitute maintains full compliance with REACH regulations and operates across the same temperature range.

Key considerations for selection:

Product Availability: The EMIF08-1005M16 is in active production status with current inventory availability, whereas the AOZ8010DTL is obsolete.
Regulatory Compliance: Both parts are REACH Unaffected and carry identical ECCN and HTSUS classifications.
Package Footprint: The EMIF08-1005M16 features a slightly smaller footprint (3.30 mm × 1.50 mm versus 4.00 mm × 1.60 mm), which may provide layout advantages in space-constrained applications.
Current Rating Difference: The EMIF08-1005M16 is rated for 10 mA maximum current, compared to 20 mA for the AOZ8010DTL. Applications requiring currents above 10 mA must be evaluated against this specification.
Frequency Response: The higher capacitance value in the EMIF08-1005M16 results in a 10 MHz higher cutoff frequency and slightly reduced attenuation in the specified frequency bands.

Frequently Asked Questions (FAQ)

Q: Can the EMIF08-1005M16 directly replace the AOZ8010DTL in existing designs?

A: Direct replacement is possible from a package and pinout perspective, as both use the 16-UFDFN Exposed Pad form factor. However, the different capacitance values (45 pF versus 28 pF) result in different frequency response characteristics. Applications sensitive to cutoff frequency or attenuation performance must evaluate whether the EMIF08-1005M16 meets the required filtering specifications.

Q: What is the impact of the capacitance difference between these parts?

A: The EMIF08-1005M16 uses 45 pF total capacitance compared to 28 pF in the AOZ8010DTL. This results in a higher cutoff frequency (100 MHz versus 90 MHz) and different attenuation characteristics across frequency bands. The attenuation specification shifts from -35 dB @ 800 MHz ~ 2.2 GHz to -34 dB @ 900 MHz ~ 1.8 GHz.

Q: Are there current rating limitations with the EMIF08-1005M16?

A: Yes. The EMIF08-1005M16 is rated for a maximum of 10 mA, whereas the AOZ8010DTL supports 20 mA. Applications requiring currents between 10 mA and 20 mA cannot use the EMIF08-1005M16 as a substitute.

Q: Do both parts have identical package dimensions?

A: No. While both use the 16-UFDFN Exposed Pad package type, the EMIF08-1005M16 has a smaller footprint (3.30 mm × 1.50 mm × 0.60 mm) compared to the AOZ8010DTL (4.00 mm × 1.60 mm × 0.60 mm). The height remains identical at 0.60 mm.

Q: Are there any compliance or regulatory differences?

A: No. Both parts are REACH Unaffected, carry identical ECCN (EAR99) and HTSUS (8548.00.0000) classifications, and maintain MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What applications are these filters designed for?

A: Both the AOZ8010DTL and EMIF08-1005M16 are specified for data line protection in mobile devices, utilizing RC (Pi) EMI filtering topology for low-pass signal conditioning.
