Substitute Part Grouping Explanation

The FN1220024 is identified as a manufacturer-recommended substitute for the FN1220025. Both parts share identical electrical specifications for frequency (12.288 MHz), output type (CMOS), supply voltage (3.3V), enable/disable function, frequency stability (±50ppm), maximum supply current (15mA), and disable mode current (10µA). Both devices use the same 4-SMD, No Lead package with identical physical dimensions (7.00mm x 5.00mm) and maximum seated height (1.80mm). The substitution is valid based on these matching core parameters. The primary difference between these parts is the operating temperature range, which is a specification variance rather than a functional incompatibility factor for most applications.

Parameter Comparison

Engineering Selection Recommendations

Both the FN1220025 and FN1220024 are active production parts from Diodes Incorporated with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on the application's operating temperature requirements. The FN1220025 supports an extended temperature range of -40°C to 85°C, making it suitable for industrial and automotive applications requiring wider thermal operation. The FN1220024 operates within -20°C to 70°C, appropriate for commercial and consumer-grade applications with standard temperature environments. Both parts maintain identical electrical performance, package footprint, and current consumption characteristics, ensuring direct PCB compatibility when thermal requirements are met.

Frequently Asked Questions (FAQ)

Q: Can FN1220024 be used as a direct replacement for FN1220025 in all applications?

A: Direct replacement is valid only when the application's operating temperature range falls within -20°C to 70°C. If the circuit operates below -20°C or above 70°C, the FN1220025 with its extended -40°C to 85°C range is required.

Q: Are the package footprints identical between FN1220025 and FN1220024?

A: Yes. Both parts use the 4-SMD, No Lead package with identical dimensions of 7.00mm x 5.00mm and maximum seated height of 1.80mm. PCB layout and reflow profiles are interchangeable.

Q: Do these oscillators have the same electrical performance?

A: Yes. Both parts deliver 12.288 MHz output with ±50ppm frequency stability, 3.3V CMOS operation, 15mA maximum supply current, and 10µA disable mode current. Electrical performance is identical.

Q: What is the significance of the operating temperature difference?

A: Operating temperature range defines the thermal environment in which the oscillator maintains specified electrical performance. The FN1220025 guarantees operation across -40°C to 85°C, while FN1220024 is specified for -20°C to 70°C. Selection depends on your application's thermal requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both FN1220025 and FN1220024 are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), meeting current environmental and reliability standards.
