FN3330070 Equivalent & Substitute Parts

Part Overview

The FN3330070 is a 33.333 MHz XO (Standard) CMOS oscillator manufactured by Diodes Incorporated, part of the SaRonix-eCera™ FN series. This surface mount crystal oscillator operates at 3.3V with Enable/Disable functionality, housed in a 4-SMD, No Lead package. The device is Active product status and ROHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, design flexibility, or application-specific performance requirements.

Substitute Part Grouping Explanation

The FN3330075 is identified as a manufacturer-recommended substitute for the FN3330070. Both parts share identical core electrical and mechanical specifications:

Matching Parameters:

• Frequency: 33.333 MHz
• Output: CMOS
• Supply Voltage: 3.3V
• Function: Enable/Disable
• Package: 4-SMD, No Lead
• Dimensions: 7.00mm x 5.00mm x 1.80mm (Max Height)
• Current Supply (Max): 25mA
• Current Supply (Disable): 10µA
• RoHS Status: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

Differing Parameters:

• Frequency Stability: FN3330070 (±25ppm) vs. FN3330075 (±50ppm)
• Operating Temperature Range: FN3330070 (-20°C ~ 70°C) vs. FN3330075 (-40°C ~ 85°C)

Substitution is valid when the application tolerates the wider frequency stability specification and extended temperature range of the FN3330075.

Parameter Comparison

Engineering Selection Recommendations

Both FN3330070 and FN3330075 are Active products with ROHS3 compliance and identical mechanical compatibility. Selection between these parts depends on application-specific requirements:

Select FN3330070 when:

• Tighter frequency stability (±25ppm) is required
• Operating environment is limited to -20°C ~ 70°C range

Select FN3330075 when:

• Extended operating temperature range (-40°C ~ 85°C) is required
• Wider frequency stability tolerance (±50ppm) is acceptable
• Broader environmental conditions must be supported

Both parts are electrically and mechanically interchangeable in the 4-SMD, No Lead package format. No PCB layout modifications are required for substitution.

Frequently Asked Questions (FAQ)

Q: Are FN3330070 and FN3330075 pin-compatible? A: Yes. Both parts use the identical 4-SMD, No Lead package with matching pinout, dimensions (7.00mm x 5.00mm x 1.80mm max height), and electrical interface (3.3V CMOS output with Enable/Disable function).

Q: What is the primary difference between these oscillators? A: The FN3330075 offers extended operating temperature range (-40°C ~ 85°C versus -20°C ~ 70°C) and wider frequency stability tolerance (±50ppm versus ±25ppm). Both maintain identical frequency (33.333 MHz), output type (CMOS), and current specifications.

Q: Can FN3330075 replace FN3330070 in all applications? A: Substitution is valid when the application can tolerate the wider frequency stability specification (±50ppm) and does not require the tighter ±25ppm stability of the FN3330070. Temperature range compatibility must also be confirmed.

Q: Are there any compliance or certification differences? A: No. Both parts are ROHS3 compliant, carry MSL Rating 1 (Unlimited), and are REACH Unaffected with identical ECCN and HTSUS classifications.

Q: What is the moisture sensitivity level for these parts? A: Both FN3330070 and FN3330075 carry MSL Rating 1, indicating unlimited shelf life with no moisture sensitivity restrictions.
