Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN2700068 is determined by strict equivalence across the following critical parameters:

• Frequency: 27 MHz (exact match required)
• Output Type: CMOS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Operating Temperature Range: -20°C ~ 70°C (exact match required)
• Package / Case: 4-SMD, No Lead (exact match required)
• Size / Dimension: 0.276" L x 0.197" W (7.00mm x 5.00mm) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

The SXO75C3C271-27.000M from Suntsu Electronics, Inc. meets all critical substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the FN2700068 and SXO75C3C271-27.000M maintain Active product status and ROHS3 compliance. The SXO75C3C271-27.000M demonstrates lower maximum seated height (1.60mm versus 1.80mm) and marginally higher maximum supply current (16mA versus 15mA), both within acceptable tolerance for direct substitution in applications designed for the FN2700068. Component selection should be based on availability, lead time, and procurement requirements, as electrical and mechanical compatibility is established across all critical parameters.

Frequently Asked Questions (FAQ)

Q: Can the SXO75C3C271-27.000M be used as a direct replacement for the FN2700068?

A: Yes. Both components share identical frequency (27 MHz), output type (CMOS), supply voltage (3.3V), enable/disable function, frequency stability (±25ppm), operating temperature range (-20°C ~ 70°C), package type (4-SMD, No Lead), and physical dimensions (7.00mm x 5.00mm). RoHS3 compliance is maintained across both parts.

Q: Are there differences in physical height between these parts?

A: The SXO75C3C271-27.000M has a maximum seated height of 1.60mm compared to 1.80mm for the FN2700068. This 0.20mm difference is compatible with standard PCB assembly processes and does not affect substitution eligibility.

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

A: The FN2700068 specifies a maximum supply current of 15mA, while the SXO75C3C271-27.000M specifies 16mA. This 1mA difference is within normal component tolerance and does not impact circuit design or power budget calculations for typical applications.

Q: Are both parts suitable for the same PCB footprint?

A: Yes. Both components use identical 4-SMD, No Lead packaging with matching physical dimensions (0.276" L x 0.197" W / 7.00mm x 5.00mm), ensuring compatibility with the same PCB footprint and assembly process.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both the FN2700068 and SXO75C3C271-27.000M are ROHS3 compliant and carry EAR99 ECCN classification, meeting equivalent regulatory requirements for industrial and commercial applications.
