Parameter Comparison

Engineering Selection Recommendations

Both the FD5000033 and SXO53C3C271-50.000M are active production parts with ROHS3 compliance and equivalent electrical specifications. Selection between these parts should be based on:

• Supply Chain Availability: SXO53C3C271-50.000M currently has higher inventory (5907 units) compared to FD5000033 (734 units)
• Regulatory Compliance: Both parts meet ROHS3 requirements and are suitable for applications with environmental compliance mandates
• Physical Compatibility: Maximum seated height differs by 0.10mm (1.30mm vs 1.40mm); verify PCB clearance in space-constrained applications
• Manufacturer Support: Select based on preferred vendor relationship and technical support requirements

Frequently Asked Questions (FAQ)

Q: Can SXO53C3C271-50.000M be used as a direct replacement for FD5000033?

A: Yes. Both parts share identical electrical specifications including frequency, output type, supply voltage, frequency stability, operating temperature range, and package footprint. The 0.10mm difference in maximum seated height is within typical PCB design tolerances for 4-SMD components.

Q: Are there any functional differences between these oscillators?

A: No. Both parts provide identical CMOS output at 50 MHz with 3.3V supply, ±25ppm frequency stability, and enable/disable control functionality across the -20°C to 70°C operating range.

Q: What is the significance of the 4-SMD, No Lead package type?

A: This package designation indicates a surface mount oscillator with four solder pads and no through-hole leads. Both parts use this identical package, ensuring PCB footprint compatibility and reflow soldering compatibility.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both FD5000033 and SXO53C3C271-50.000M are ROHS3 compliant and carry EAR99 ECCN classification, meeting equivalent regulatory requirements for industrial and commercial applications.

Q: What should be verified when switching between these parts?

A: Verify PCB clearance for the maximum seated height specification (1.30mm for FD5000033 vs 1.40mm for SXO53C3C271-50.000M) in applications with tight vertical constraints. Confirm enable/disable signal compatibility with your circuit design, as both parts support this function identically.
