Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C3392-19.440 is determined by strict equivalence across the following critical parameters: frequency (19.44 MHz), output type (HCMOS), supply voltage (3.3V), enable/disable function, package configuration (4-SMD, No Lead), and physical dimensions (0.283" L x 0.205" W, 1.80mm max height). The CE3391-19.440 qualifies as a direct substitute because it maintains identical values for all these parameters. Secondary parameters including frequency stability, operating temperature range, and current consumption may differ between the main part and substitute without affecting substitutability, provided the substitute meets or exceeds the performance requirements of the application circuit.

Parameter Comparison

Engineering Selection Recommendations

Both C3392-19.440 and CE3391-19.440 are Active status products manufactured by Crystek Corporation with ROHS3 compliance and identical mechanical compatibility. The CE3391-19.440 provides enhanced performance characteristics with tighter frequency stability (±25ppm versus ±50ppm) and an extended operating temperature range (-40°C to 85°C versus 0°C to 70°C). Selection between these parts should be based on application-specific requirements: the C3392-19.440 is suitable for standard industrial temperature environments with standard frequency tolerance requirements, while the CE3391-19.440 is appropriate for applications requiring wider temperature operation or tighter frequency control. Both parts maintain identical electrical and mechanical interfaces, enabling direct substitution without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can CE3391-19.440 be used as a direct replacement for C3392-19.440 in existing designs?

A: Yes. Both parts share identical frequency (19.44 MHz), output type (HCMOS), supply voltage (3.3V), enable/disable function, package configuration (4-SMD, No Lead), and physical dimensions. No PCB layout or schematic modifications are required for substitution.

Q: What are the key differences between these parts?

A: The CE3391-19.440 offers improved frequency stability (±25ppm versus ±50ppm) and an extended operating temperature range (-40°C to 85°C versus 0°C to 70°C). Both parts maintain identical current consumption (18mA maximum) and mechanical form factor.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and maintain Active product status. REACH and ECCN classifications are identical.

Q: Which part should be selected for high-temperature applications?

A: The CE3391-19.440 is specified for operation to 85°C and is appropriate for applications requiring extended temperature performance. The C3392-19.440 is limited to 70°C maximum operating temperature.

Q: Are the parts interchangeable at the PCB assembly level?

A: Yes. Identical package type (4-SMD, No Lead), dimensions (7.20mm x 5.20mm), and maximum height (1.80mm) ensure mechanical and electrical interchangeability without assembly process modifications.
