Parameter Comparison

Engineering Selection Recommendations

Both the FN1200037 and SXO75C3A271-12.000M are active production parts with full RoHS3 compliance and identical regulatory classifications. The SXO75C3A271-12.000M offers higher inventory availability (4086 units) compared to the FN1200037 (639 units), making it suitable for high-volume applications. The Suntsu part features a lower maximum seated height (1.60mm vs. 1.80mm), which may provide design advantages in space-constrained applications. Maximum supply current differs marginally (16mA vs. 15mA), remaining within typical circuit design tolerances. Both parts are suitable for direct substitution in applications requiring 12 MHz CMOS oscillators with enable/disable control at 3.3V supply voltage.

Frequently Asked Questions (FAQ)

Q: Can the SXO75C3A271-12.000M replace the FN1200037 in existing designs?

A: Yes. Both parts share identical electrical specifications (frequency, output type, supply voltage, function, and frequency stability) and mechanical specifications (package type and dimensions). The parts are pin-compatible and functionally equivalent.

Q: What is the significance of the height difference (1.80mm vs. 1.60mm)?

A: The SXO75C3A271-12.000M has a lower maximum seated height. This is compatible with the FN1200037 footprint and may provide additional clearance in PCB designs with height constraints.

Q: Are there any supply current differences to consider?

A: The maximum supply current differs by 1mA (FN1200037: 15mA; SXO75C3A271-12.000M: 16mA). This marginal difference is negligible for most circuit designs and does not affect substitution suitability.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant, classified under ECCN EAR99, and share the same HTSUS code (8542.39.0001), confirming identical regulatory status.

Q: What packaging options are available for the SXO75C3A271-12.000M?

A: The SXO75C3A271-12.000M is supplied in bulk packaging, whereas the FN1200037 packaging specification was not provided in the source data. Confirm packaging requirements with your procurement department.

Q: Is the disable mode current specification available for the SXO75C3A271-12.000M?

A: The disable mode current specification for the SXO75C3A271-12.000M is not provided in the available data. The FN1200037 specifies 10µA maximum in disable mode. Consult the manufacturer datasheet for the Suntsu part if disable mode current is a critical design parameter.
