Engineering Selection Recommendations
Both the FN1600045 and SXO75C3A481-16.000M are active production parts with full ROHS3 compliance and EAR99 classification. The SXO75C3A481-16.000M offers a lower seated height (1.60mm vs. 1.80mm) and marginally higher supply current specification (16mA vs. 15mA), both of which remain within acceptable design tolerances for standard applications. Selection between these parts should be based on availability, procurement lead times, and cost considerations, as all critical electrical and mechanical parameters are equivalent.
Frequently Asked Questions (FAQ)
Q: Can the SXO75C3A481-16.000M be used as a direct replacement for the FN1600045 in existing designs?
A: Yes. Both parts share identical frequency, output type, supply voltage, enable/disable function, frequency stability, operating temperature range, and package footprint. The physical dimensions and electrical specifications are compatible for direct PCB substitution.
Q: Are there any height clearance concerns when substituting the SXO75C3A481-16.000M?
A: The SXO75C3A481-16.000M has a lower seated height (1.60mm) compared to the FN1600045 (1.80mm). This difference presents no compatibility issues and may provide additional clearance in space-constrained designs.
Q: Do both parts meet the same regulatory requirements?
A: Yes. Both parts are ROHS3 compliant, carry EAR99 ECCN classification, and share identical HTSUS codes (8542.39.0001), confirming equivalent regulatory status.
Q: What is the difference in supply current between these parts?
A: The FN1600045 specifies a maximum supply current of 15mA, while the SXO75C3A481-16.000M specifies 16mA. This 1mA difference is negligible for most applications and does not affect circuit design or power budget calculations.
Q: Are both parts available in the same packaging format?
A: Yes. Both parts use 4-SMD, No Lead packaging with identical 7.00mm x 5.00mm footprints, ensuring compatibility with existing PCB layouts and assembly processes.
