Key Parameters

Substitute Part Grouping Explanation

Substitution of the FN3330044 is determined by the following critical parameters:

• Manufacturer & Series Alignment: Both the main part and substitute must originate from Diodes Incorporated within the SaRonix-eCera™ FN series to ensure design compatibility and performance consistency.
• Oscillator Type: The substitute must be classified as XO (Standard) with a crystal base resonator, maintaining functional equivalence.
• Regulatory Compliance: RoHS and REACH compliance status must be maintained or upgraded to ensure regulatory continuity.
• Moisture Sensitivity: MSL rating of 1 (Unlimited) ensures handling and storage compatibility.
• Packaging Consideration: While the main part uses Tape & Reel (TR) packaging, the substitute may utilize alternative packaging formats (such as Bulk) provided the component itself maintains electrical and mechanical compatibility.

The FN3330071 qualifies as a direct substitute based on these parameters, with the additional benefit of Active product status and fully specified electrical characteristics.
