Parameter Comparison

Engineering Selection Recommendations

Both the CSX-750FBB27000000T and SXO75C3A271-27.000M are Active products with RoHS3 compliance and EAR99 export classification. The SXO75C3A271-27.000M exhibits a maximum supply current of 16mA compared to 15mA for the Citizen device, representing a 1mA differential within typical circuit design margins. Both devices meet identical electrical and mechanical specifications for 27 MHz CMOS oscillator applications requiring enable/disable control at 3.3V operation. Selection between these parts may be based on availability, packaging format (Tape & Reel versus Bulk), or supply chain requirements.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the CSX-750FBB27000000T?

A: Substitution requires matching frequency (27 MHz), output type (CMOS), supply voltage (3.3V), function (Enable/Disable), frequency stability (±50ppm), operating temperature range (-20°C ~ 70°C), and package specifications (4-SMD, No Lead, 7.00mm x 5.00mm, 1.60mm max height).

Q: Is the SXO75C3A271-27.000M mechanically compatible with the CSX-750FBB27000000T?

A: Yes. Both devices use identical 4-SMD, No Lead packaging with matching dimensions (7.00mm x 5.00mm) and maximum seated height (1.60mm), ensuring PCB footprint compatibility.

Q: What is the difference in supply current between these parts?

A: The CSX-750FBB27000000T draws a maximum of 15mA, while the SXO75C3A271-27.000M draws a maximum of 16mA. This 1mA difference is within standard circuit design tolerances for most applications.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the CSX-750FBB27000000T and SXO75C3A271-27.000M are RoHS3 compliant and carry EAR99 export classification.

Q: What is the difference in packaging format?

A: The CSX-750FBB27000000T is supplied in Tape & Reel format, while the SXO75C3A271-27.000M is supplied in Bulk format. Both formats contain the same component; packaging selection depends on assembly process requirements and order quantities.
