Key Parameters

Substitute Part Grouping Explanation

The CWX823-025.0M qualifies as a direct substitute based on the following critical parameters:

• Frequency: 25 MHz (exact match)
• Output Type: LVCMOS (exact match)
• Supply Voltage: 3.3V (exact match)
• Function: Enable/Disable (exact match)
• Frequency Stability: ±50ppm (exact match)
• Operating Temperature Range: -20°C ~ 70°C (exact match)
• Package / Case: 4-SMD, No Lead (exact match)
• Mounting Type: Surface Mount (exact match)
• RoHS Status: ROHS3 Compliant (exact match)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match)

All electrical and mechanical parameters align within the specified tolerances for direct substitution in applications requiring a 25 MHz LVCMOS oscillator with Enable/Disable control.

Parameter Comparison

Engineering Selection Recommendations

Both the FN2500264Z and CWX823-025.0M are Active status components with ROHS3 compliance and REACH Unaffected certification. The CWX823-025.0M exhibits a lower seated height (0.051" vs 0.071") and higher maximum supply current (30mA vs 15mA). Selection between these parts depends on application-specific requirements regarding power consumption and PCB clearance constraints. Both parts maintain identical electrical performance across frequency, stability, output type, and operating temperature specifications.

Frequently Asked Questions (FAQ)

Q: Can the CWX823-025.0M replace the FN2500264Z in existing designs?

A: Yes. Both parts share identical frequency (25 MHz), output type (LVCMOS), supply voltage (3.3V), function (Enable/Disable), frequency stability (±50ppm), operating temperature range (-20°C ~ 70°C), and package configuration (4-SMD, No Lead). Electrical and mechanical compatibility is maintained.

Q: What are the differences between these two parts?

A: The primary differences are maximum supply current (FN2500264Z: 15mA; CWX823-025.0M: 30mA) and seated height (FN2500264Z: 1.80mm; CWX823-025.0M: 1.30mm). These differences do not affect substitution eligibility for standard applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the FN2500264Z and CWX823-025.0M are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What package type do these oscillators use?

A: Both parts use a 4-SMD, No Lead surface mount package with identical footprint dimensions (7.00mm x 5.00mm).

Q: Is there a difference in frequency stability between these parts?

A: No. Both parts maintain ±50ppm frequency stability across the specified operating temperature range.
