Substitute Part Grouping Explanation

Substitution eligibility for the FD2000046 is determined by strict equivalence across the following critical parameters:

• Frequency: 20 MHz (exact match required)
• Output: CMOS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Frequency Stability: ±50ppm (exact match required)
• Operating Temperature: -20°C ~ 70°C (exact match required)
• Package: 4-SMD, No Lead (exact match required)
• Package Dimensions: 5.00mm x 3.20mm (exact match required)
• Function: Enable/Disable (exact match required)
• Compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

The substitute part SXO53C3A271-20.000M from Suntsu Electronics, Inc. meets all critical electrical and mechanical parameters, enabling direct substitution in applications where the FD2000046 is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the FD2000046 and SXO53C3A271-20.000M are active production parts with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and use. The SXO53C3A271-20.000M operates within compatible current specifications (16mA vs. 15mA maximum supply current) and maintains identical frequency stability and operating temperature ranges. The maximum seated height difference of 0.10mm (1.40mm vs. 1.30mm) remains within typical PCB assembly tolerances for 4-SMD packages. Selection between these parts may be based on availability, lead time, or supply chain requirements, as both meet the specified electrical and mechanical criteria for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can the SXO53C3A271-20.000M replace the FD2000046 in existing designs?

A: Yes. Both parts share identical frequency (20 MHz), output type (CMOS), supply voltage (3.3V), frequency stability (±50ppm), operating temperature range (-20°C ~ 70°C), package type (4-SMD, No Lead), and package dimensions (5.00mm x 3.20mm). The 0.10mm height difference and 1mA additional current capacity are within acceptable tolerances for standard PCB assembly and circuit operation.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant and REACH unaffected, meeting identical regulatory standards for use in electronic equipment.

Q: What is the significance of the Enable/Disable function in these oscillators?

A: The Enable/Disable function allows the oscillator output to be controlled via an external signal, enabling power management in applications where the 20 MHz clock is not continuously required. Both parts provide this functionality identically.

Q: Does the 1mA difference in maximum supply current affect circuit design?

A: No. The SXO53C3A271-20.000M maximum supply current of 16mA is marginally higher than the FD2000046 at 15mA. This difference is negligible in typical circuit designs and does not require modifications to power supply or current limiting components.

Q: Are these parts pin-compatible?

A: Yes. Both parts use the 4-SMD, No Lead package with identical 5.00mm x 3.20mm footprint dimensions, ensuring direct PCB compatibility without layout modifications.
