Substitute Part Grouping Explanation

Substitution eligibility for the FN2700070 is determined by strict equivalence across the following critical parameters:

• Frequency: Exact match at 27 MHz
• Output Configuration: CMOS output required
• Supply Voltage: 3.3V operation mandatory
• Enable/Disable Function: Control capability must be present
• Frequency Stability: ±50ppm tolerance
• Operating Temperature Range: -40°C to 85°C minimum
• Package Type: 4-SMD, no-lead configuration
• Package Dimensions: 7.00mm x 5.00mm footprint
• Regulatory Compliance: ROHS3 compliant

The SXO75C3A481-27.000M from Suntsu Electronics meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The SXO75C3A481-27.000M is a direct functional equivalent to the FN2700070. Both devices are ROHS3 compliant and carry identical ECCN and HTSUS classifications, ensuring regulatory and trade compliance equivalence. The maximum supply current of the Suntsu part (16mA) is marginally higher than the Diodes part (15mA), remaining within acceptable design tolerances for 3.3V CMOS oscillator applications. The Suntsu device features a lower seated height (1.60mm versus 1.80mm), which provides additional clearance margin in space-constrained PCB layouts. Both parts maintain identical frequency stability and operating temperature specifications, ensuring functional interchangeability in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the SXO75C3A481-27.000M be used as a direct replacement for the FN2700070?

A: Yes. Both parts are functionally equivalent across all critical parameters: 27 MHz frequency, CMOS output, 3.3V supply, enable/disable control, ±50ppm stability, and -40°C to 85°C operating range. The package footprint and dimensions are identical.

Q: Are there differences in power consumption between these parts?

A: The maximum supply current differs slightly: FN2700070 draws 15mA maximum, while SXO75C3A481-27.000M draws 16mA maximum. This 1mA difference is negligible for most 3.3V applications and does not affect functional compatibility.

Q: Do both parts have the same physical height?

A: No. The FN2700070 has a maximum seated height of 1.80mm, while the SXO75C3A481-27.000M is 1.60mm. The Suntsu part is 0.20mm lower, which may be advantageous in applications with height constraints.

Q: Are regulatory certifications equivalent?

A: Yes. Both parts are ROHS3 compliant and share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications, ensuring equivalent regulatory and trade compliance status.

Q: What is the moisture sensitivity level for both parts?

A: The FN2700070 is rated MSL 1 (Unlimited). The SXO75C3A481-27.000M moisture sensitivity level is not specified in the provided data.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. Both parts use identical 4-SMD, no-lead packaging with 7.00mm x 5.00mm footprints, enabling direct PCB layout compatibility without design modifications.
