Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FN1200041 are qualified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

• Frequency Match: Exact 12 MHz output frequency
• Output Configuration: CMOS logic output
• Supply Voltage: 3.3V operation
• Functional Capability: Enable/Disable control function
• Package Compatibility: 4-SMD, no-lead form factor with matching footprint dimensions (7.00mm x 5.00mm)
• Frequency Stability: ±50ppm tolerance
• Operating Temperature: -40°C to 85°C range
• Compliance: ROHS3 compliant, EAR99 classification

The SXO75C3A481-12.000M from Suntsu Electronics meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the FN1200041 and SXO75C3A481-12.000M are active production devices with ROHS3 compliance and EAR99 classification. The Suntsu substitute exhibits a lower maximum seated height (1.60mm versus 1.80mm), which provides additional clearance margin in space-constrained applications. The maximum supply current of the Suntsu part is 16mA compared to 15mA for the Diodes part, representing a 1mA difference within typical design tolerances. Both parts maintain identical electrical specifications for frequency, stability, output type, and operating temperature range. Selection between these parts should be based on supplier availability, lead time requirements, and inventory management objectives, as both meet all specified electrical and mechanical requirements.

Frequently Asked Questions (FAQ)

Q: Can the SXO75C3A481-12.000M be used as a direct replacement for the FN1200041?

A: Yes. Both parts share identical frequency (12 MHz), output type (CMOS), supply voltage (3.3V), enable/disable function, package type (4-SMD, no lead), package dimensions (7.00mm x 5.00mm), frequency stability (±50ppm), and operating temperature range (-40°C to 85°C). The parts are electrically and mechanically interchangeable.

Q: What are the differences between these two parts?

A: The maximum supply current differs by 1mA (FN1200041: 15mA; SXO75C3A481-12.000M: 16mA). The seated height of the Suntsu part is 0.2mm lower (1.60mm versus 1.80mm). These differences do not affect functional compatibility in standard applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the FN1200041 and SXO75C3A481-12.000M are ROHS3 compliant and carry EAR99 export classification.

Q: What is the moisture sensitivity level for these oscillators?

A: The FN1200041 has a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.

Q: Can these parts be used in applications requiring frequencies other than 12 MHz?

A: No. Both parts are specified exclusively for 12 MHz operation. Alternative frequency oscillators require different part numbers.

Q: What is the frequency stability specification?

A: Both parts maintain ±50ppm frequency stability across the operating temperature range of -40°C to 85°C.
