• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Frequency Stability: ±50ppm (exact match required)
• Operating Temperature Range: -20°C ~ 70°C (exact match required)
• Package / Case: 4-SMD, No Lead (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Physical Dimensions: 7.00mm x 5.00mm (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• MSL Rating: 1 (Unlimited) (exact match required)

The CWX823-025.0M from Connor Winfield meets all critical substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the FN2500246 and CWX823-025.0M are Active status products with identical electrical and mechanical specifications for core oscillator functionality. Both devices are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. The CWX823-025.0M exhibits a lower seated height (1.30mm vs. 1.80mm) and higher maximum supply current (30mA vs. 15mA), both of which are compatible with standard PCB design practices and do not restrict substitution. Selection between these parts may be based on availability, lead time, or supply chain requirements, as both meet identical functional and compliance criteria.

Frequently Asked Questions (FAQ)

Q: Can the CWX823-025.0M be used as a direct replacement for the FN2500246?

A: Yes. Both parts share identical frequency (25 MHz), output type (LVCMOS), supply voltage (3.3V), enable/disable function, frequency stability (±50ppm), operating temperature range (-20°C ~ 70°C), package type (4-SMD, No Lead), and physical dimensions (7.00mm x 5.00mm). All critical substitution parameters match.

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

A: The CWX823-025.0M has a maximum seated height of 1.30mm, while the FN2500246 is 1.80mm. The lower profile of the CWX823-025.0M is compatible with standard PCB layouts and does not restrict substitution.

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

A: The FN2500246 specifies a maximum supply current of 15mA, while the CWX823-025.0M specifies 30mA. Both values are within typical design margins for 3.3V oscillator applications and do not prevent substitution.

Q: Are both parts compliant with environmental and trade regulations?

A: Yes. Both the FN2500246 and CWX823-025.0M are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

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

A: Both parts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
