Parameter Comparison

Engineering Selection Recommendations

Both FN3000038 and FN3000041 are Active status products from Diodes Incorporated with identical ROHS3 compliance and MSL ratings. Selection between these parts should be based on application requirements:

Select FN3000038 when:

• Operating temperature range of -20°C ~ 70°C is sufficient for the application
• Frequency stability of ±50ppm meets system timing requirements
• Current inventory availability is a priority

Select FN3000041 when:

• Extended temperature operation (-40°C ~ 85°C) is required
• Improved frequency stability (±25ppm) is necessary for system performance
• Long-term reliability in variable thermal environments is critical

Both parts maintain identical electrical performance in supply voltage, output type, current consumption, and package form factor, ensuring direct PCB-level compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can FN3000041 be used as a direct replacement for FN3000038 on existing PCBs?

A: Yes. Both parts share identical package dimensions (7.00mm x 5.00mm x 1.80mm), pinout configuration (4-SMD, No Lead), electrical specifications (3.3V supply, 15mA max current, CMOS output), and functional characteristics (Enable/Disable). No PCB redesign or component repositioning is required.

Q: What is the primary difference between these two parts?

A: The FN3000041 offers improved frequency stability (±25ppm vs. ±50ppm) and extended operating temperature range (-40°C ~ 85°C vs. -20°C ~ 70°C). All other electrical and mechanical parameters remain identical.

Q: Are both parts RoHS compliant?

A: Yes. Both FN3000038 and FN3000041 are ROHS3 Compliant with MSL Rating 1 (Unlimited moisture sensitivity level).

Q: Which part should be selected for industrial temperature applications?

A: The FN3000041 is suitable for industrial temperature ranges due to its -40°C ~ 85°C operating specification. The FN3000038 is limited to -20°C ~ 70°C and is better suited for commercial temperature environments.

Q: Do these oscillators require any external components for operation?

A: The provided specifications indicate these are complete XO (Standard) oscillators with integrated enable/disable functionality. No external resonator or load capacitors are required.

Q: Is frequency stability a critical factor in my application?

A: Frequency stability becomes critical in applications with tight timing tolerances, such as high-speed data communication, precision timing circuits, or systems requiring long-term frequency accuracy. The FN3000041's ±25ppm specification provides superior stability compared to the FN3000038's ±50ppm.
