Key Parameters

Substitute Part Grouping Explanation

Substitution of the FN1500004 is based on the following criteria derived from the provided parameters:

Primary Substitution Criteria:

• Manufacturer: Diodes Incorporated (same manufacturer ensures design continuity)
• Series: SaRonix-eCera™ FN (maintains product line compatibility)
• Type: XO (Standard) (functional oscillator classification)
• Base Resonator: Crystal (same resonator technology)
• Compliance: RoHS and REACH status alignment
• Moisture Sensitivity: MSL 1 (Unlimited) compatibility

The FN1500011 qualifies as a direct substitute based on these parameters. Both parts share the same manufacturer, series designation, oscillator type, and crystal-based resonator architecture. Both maintain equivalent compliance certifications and moisture sensitivity ratings.

Parameter Comparison

Engineering Selection Recommendations

The FN1500011 is the manufacturer-recommended substitute for the obsolete FN1500004. Selection is justified on the following basis:

Product Status: The FN1500004 is obsolete, while the FN1500011 maintains active product status, ensuring long-term availability and continued manufacturer support.

Compliance Alignment: Both parts maintain equivalent environmental compliance. The FN1500011 carries ROHS3 Compliant status, representing current regulatory standards. Both parts are REACH Unaffected and classified under ECCN EAR99.

Moisture Sensitivity: Both parts share MSL 1 (Unlimited) rating, indicating identical moisture handling and storage requirements.

Series Continuity: Both parts belong to the SaRonix-eCera™ FN series from Diodes Incorporated, maintaining design lineage and manufacturer support infrastructure.

Frequently Asked Questions (FAQ)

Q: Can the FN1500011 directly replace the FN1500004 in existing designs?

A: The FN1500011 is the manufacturer-recommended substitute and shares the same oscillator type, resonator technology, series designation, and compliance certifications. However, physical package differences exist between the SEAM7050 (FN1500004) and 4-SMD, No Lead (FN1500011) formats. PCB layout and mounting considerations must be evaluated for your specific application.

Q: What is the significance of the product status change from Obsolete to Active?

A: The FN1500011's active status ensures continued manufacturing, availability, and technical support from Diodes Incorporated. This eliminates supply chain risk associated with obsolete components and provides access to current product documentation and application support.

Q: Are the RoHS compliance levels equivalent between these parts?

A: Both parts are RoHS compliant. The FN1500004 carries RoHS Compliant status, while the FN1500011 carries ROHS3 Compliant status, representing alignment with current regulatory requirements. Both are suitable for applications requiring RoHS compliance.

Q: What packaging differences should I consider?

A: The FN1500004 uses SEAM7050 packaging, while the FN1500011 uses 4-SMD, No Lead packaging with dimensions of 7.00mm x 5.00mm and maximum seated height of 1.80mm. Verify that your PCB design accommodates the FN1500011's surface mount footprint and height specifications.

Q: Are moisture sensitivity requirements the same?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating identical moisture sensitivity levels and equivalent handling, storage, and reflow requirements.
