Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FN3330069 are qualified based on the following critical parameters:

• Frequency Match: 33.333 MHz (exact)
• Output Configuration: CMOS
• Supply Voltage: 3.3V
• Function: Enable/Disable capability
• Frequency Stability: ±50ppm
• Package / Case: 4-SMD, No Lead (identical footprint and mounting)
• Physical Dimensions: 0.276" L x 0.197" W (7.00mm x 5.00mm) with maximum seated height of 0.071" (1.80mm)
• Current Specifications: 25mA maximum supply current and 10µA maximum disable current
• Compliance: ROHS3 Compliant, MSL 1

The FN3330075 qualifies as a direct substitute when these parameters are maintained. Variations in operating temperature range do not disqualify substitution when the application operates within the overlapping temperature window.

Parameter Comparison

Engineering Selection Recommendations

The FN3330075 is a qualified substitute for the FN3330069 based on electrical and mechanical parameter equivalence. Both parts are Active status products from Diodes Incorporated within the SaRonix-eCera™ FN series. Both maintain ROHS3 compliance and REACH Unaffected status, meeting regulatory requirements for industrial and commercial applications.

The FN3330075 provides an extended operating temperature range (-40°C ~ 85°C) compared to the FN3330069 (-20°C ~ 70°C). Applications operating within the FN3330069 temperature window (-20°C ~ 70°C) may use either part interchangeably. Applications requiring extended low-temperature operation below -20°C or high-temperature operation above 70°C must use the FN3330075.

Both parts share identical electrical specifications (frequency, stability, current consumption, voltage), output configuration (CMOS with Enable/Disable), and physical packaging (4-SMD, No Lead, 7.00mm x 5.00mm x 1.80mm maximum height). PCB layout and schematic integration are directly compatible.

Frequently Asked Questions (FAQ)

Q: Can FN3330075 replace FN3330069 in all applications?

A: Yes, when the application operates within the overlapping temperature range of -20°C ~ 70°C. The FN3330075 is electrically and mechanically equivalent and maintains identical frequency, stability, current consumption, and package specifications. For applications requiring temperatures below -20°C or above 70°C, the FN3330075 provides extended range coverage.

Q: Are the packages physically identical?

A: Yes. Both parts use 4-SMD, No Lead packaging with identical dimensions of 0.276" L x 0.197" W (7.00mm x 5.00mm) and maximum seated height of 0.071" (1.80mm). PCB footprints are directly compatible without layout modification.

Q: Do both parts have the same frequency stability?

A: Yes. Both FN3330069 and FN3330075 maintain ±50ppm frequency stability at 33.333 MHz.

Q: What is the difference between these parts?

A: The primary difference is operating temperature range. FN3330069 operates from -20°C ~ 70°C, while FN3330075 operates from -40°C ~ 85°C. All other electrical and mechanical specifications are identical.

Q: Are both parts ROHS3 compliant?

A: Yes. Both FN3330069 and FN3330075 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level and REACH Unaffected status.

Q: Can I use FN3330069 in place of FN3330075?

A: FN3330069 can replace FN3330075 only when the application operates within the FN3330069 temperature range of -20°C ~ 70°C. Applications requiring the extended temperature range of FN3330075 must use that part.
