FN2700052 Equivalent & Substitute Parts

Part Overview

The FN2700052 is a Clock SAW Oscillator manufactured by Diodes Incorporated, part of the SaRonix-eCera™ FN series. This XO (Standard) oscillator uses a crystal base resonator and is packaged in SEAM7050 format. The part is currently classified as Obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations. With 1058 units in current inventory, alternative solutions are required for production continuity and long-term availability assurance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FN2700052 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 supply chain consistency.
• Oscillator Type: XO (Standard) classification must be maintained to preserve functional equivalence.
• Base Resonator Technology: Crystal-based resonators ensure frequency stability characteristics remain consistent.
• Compliance & Certification: RoHS and REACH compliance status must be equivalent or superior to support regulatory requirements.
• Moisture Sensitivity: MSL rating of 1 (Unlimited) provides maximum handling flexibility without additional environmental controls.

The FN2700097 qualifies as a manufacturer-recommended substitute based on these parameters. While it introduces additional functional capabilities (Enable/Disable control and CMOS output), these enhancements do not conflict with the base oscillator requirements and provide design flexibility for modern applications.

Engineering Selection Recommendations

The FN2700097 is designated as the manufacturer-recommended substitute for the obsolete FN2700052. Selection of this alternative is supported by:

• Active Product Status: The FN2700097 maintains Active status within the SaRonix-eCera™ FN series, ensuring long-term availability and continued manufacturer support.
• Enhanced Compliance: ROHS3 compliance exceeds the RoHS Compliant rating of the original part, meeting current and future regulatory requirements.
• Maintained Certifications: Both REACH Unaffected and EAR99 ECCN classifications remain unchanged, preserving export and supply chain compatibility.
• Equivalent Environmental Handling: MSL 1 (Unlimited) rating on both parts eliminates moisture sensitivity constraints during manufacturing and storage.

The transition from SEAM7050 to 4-SMD, No Lead packaging reflects current industry standards for surface mount oscillators while maintaining the same functional oscillator class and resonator technology.

Frequently Asked Questions (FAQ)

Q: Why is the FN2700052 classified as Obsolete? A: The FN2700052 has reached end-of-life status within Diodes Incorporated's product portfolio. The FN2700097 represents the current-generation equivalent within the same series, offering improved compliance and active manufacturing support.

Q: Are there functional differences between FN2700052 and FN2700097? A: Both parts are XO (Standard) oscillators with crystal base resonators. The FN2700097 adds Enable/Disable control functionality and CMOS output capability. These features are additive and do not reduce compatibility with applications designed for the base FN2700052 oscillator.

Q: What is the significance of the packaging change from SEAM7050 to 4-SMD, No Lead? A: SEAM7050 and 4-SMD, No Lead represent different physical package formats. The 4-SMD, No Lead package (7.00mm x 5.00mm x 1.80mm max height) is the current standard for this oscillator class. PCB layout and footprint modifications are required for this transition.

Q: Do both parts meet the same regulatory requirements? A: Yes. Both parts are REACH Unaffected and classified as EAR99 for export control purposes. The FN2700097 carries ROHS3 compliance, which is equivalent to or exceeds the RoHS Compliant status of the FN2700052.

Q: Is the MSL rating the same for both parts? A: Yes. Both the FN2700052 and FN2700097 carry MSL 1 (Unlimited) ratings, indicating no moisture sensitivity constraints during standard manufacturing and storage conditions.

Q: Can the FN2700097 be used as a direct replacement without design changes? A: Functional substitution is supported. However, physical package differences require PCB footprint and layout modifications. The Enable/Disable and CMOS output features of the FN2700097 are optional enhancements and do not mandate circuit redesign if not utilized.
