Key Parameters

Substitute Part Grouping Explanation

The C3391-4.096 is identified as a substitute for the C3390-4.096 based on strict equivalence of the following critical parameters:

• Identical frequency: 4.096 MHz
• Identical output type: HCMOS
• Identical supply voltage: 3.3V
• Identical function: Enable/Disable
• Identical mounting type: Surface Mount
• Identical package: 4-SMD, No Lead
• Identical physical dimensions: 0.283" L x 0.205" W (7.20mm x 5.20mm)
• Identical height: 0.071" (1.80mm)
• Identical operating temperature range: 0°C ~ 70°C
• Identical maximum supply current: 18mA
• Identical compliance certifications: ROHS3 Compliant, REACH Unaffected
• Identical moisture sensitivity level: MSL 1 (Unlimited)

The primary difference between these parts is frequency stability: the C3391-4.096 provides ±25ppm stability compared to the C3390-4.096's ±100ppm stability. This represents an improvement in frequency accuracy while maintaining all other electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the C3390-4.096 and C3391-4.096 maintain Active product status from Crystek Corporation and are fully compliant with ROHS3 and REACH regulations. The C3391-4.096 provides superior frequency stability at ±25ppm, offering enhanced performance for applications requiring tighter frequency tolerance. Both parts are functionally interchangeable at the board level due to identical pinout, package geometry, and electrical interface specifications. Selection between these parts should be based on application frequency accuracy requirements and availability.
