FN2000010 Equivalent & Substitute Parts

Part Overview

The FN2000010 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 a SEAM7050 form factor. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system support, maintenance, and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the obsolete FN2000010 is based on the following critical parameters:

• Manufacturer & Series: Parts must be from Diodes Incorporated, SaRonix-eCera™ FN series to ensure design compatibility and supply chain continuity
• Oscillator Type: XO (Standard) classification with crystal base resonator
• Compliance & Certifications: RoHS compliance, MSL rating, REACH status, and ECCN classification must be maintained or exceed the original specification
• Product Status: Active or current production status ensures long-term availability

The primary substitute, FN2000121, meets all these criteria while offering active product status and enhanced specifications including defined frequency (20 MHz), output type (CMOS), supply voltage (3.3V), and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: FN2000121

The FN2000121 is the manufacturer-recommended substitute for the obsolete FN2000010. Both parts maintain identical compliance profiles (RoHS3, REACH Unaffected, EAR99 classification) and share the same MSL rating of 1 (Unlimited). The FN2000121 is in active production status, ensuring reliable long-term availability and supply chain stability.

The transition from the obsolete FN2000010 to the FN2000121 is supported by identical regulatory and environmental compliance certifications, making it suitable for direct substitution in applications requiring SaRonix-eCera™ FN series crystal oscillators.

Frequently Asked Questions (FAQ)

Q: Can FN2000121 directly replace FN2000010 in existing designs?

A: FN2000121 is the manufacturer-recommended substitute and shares the same series designation, oscillator type, and compliance certifications. However, physical package differences (SEAM7050 vs. 4-SMD, No Lead) and dimensional specifications must be evaluated for PCB layout compatibility.

Q: What are the key compliance considerations for substitution?

A: Both parts maintain RoHS compliance (FN2000010: RoHS Compliant; FN2000121: ROHS3 Compliant), REACH Unaffected status, and EAR99 ECCN classification. MSL ratings are identical at Level 1 (Unlimited), ensuring equivalent moisture handling requirements.

Q: Are there additional substitute options beyond FN2000121?

A: FN2000121 carries secondary substitutes including SXO75C3A271-20.000M, FN2000118, and FN2000115. These alternatives should be evaluated only if FN2000121 availability is constrained, as they may introduce additional design considerations.

Q: What packaging differences exist between FN2000010 and FN2000121?

A: FN2000010 uses SEAM7050 packaging, while FN2000121 employs 4-SMD, No Lead surface mount packaging with dimensions of 7.00mm x 5.00mm and maximum seated height of 1.80mm. PCB footprint redesign may be required.

Q: How does product status affect component selection?

A: FN2000010 is obsolete, making it unavailable for new procurement. FN2000121 maintains active production status, ensuring continued availability, technical support, and supply chain reliability for both new designs and legacy system maintenance.
