Key Parameters

Substitute Part Grouping Explanation

The C3291-2.048 qualifies as a direct substitute for the CE3290-2.048 based on the following critical parameters:

• Identical frequency: 2.048 MHz
• Identical output type: HCMOS, TTL
• Identical supply voltage: 5V
• Identical function: Enable/Disable
• Identical package: 4-SMD, No Lead
• Identical physical dimensions: 7.20mm x 5.20mm x 1.80mm (Max)
• Identical mounting type: Surface Mount
• Identical current supply maximum: 60mA
• Identical compliance: ROHS3, MSL 1

The C3291-2.048 differs in frequency stability (±25ppm versus ±100ppm) and operating temperature range (0°C ~ 70°C versus -40°C ~ 85°C), representing performance enhancements rather than compatibility limitations.

Parameter Comparison

Engineering Selection Recommendations

Both CE3290-2.048 and C3291-2.048 are active products from Crystek Corporation with identical ROHS3 compliance and MSL ratings. Selection between these parts should be based on application-specific requirements:

The CE3290-2.048 is suitable for applications requiring extended operating temperature range (-40°C ~ 85°C) with standard frequency stability (±100ppm).

The C3291-2.048 is suitable for applications operating within 0°C ~ 70°C with enhanced frequency stability (±25ppm), providing tighter timing accuracy for precision-dependent circuits.

Both parts maintain identical electrical and mechanical interfaces, ensuring direct PCB-level compatibility when thermal and stability requirements are met.

Frequently Asked Questions (FAQ)

Q: Can C3291-2.048 replace CE3290-2.048 in all applications?

A: Direct replacement is possible for applications operating within 0°C ~ 70°C. Applications requiring the extended -40°C ~ 85°C temperature range must use CE3290-2.048 or verify that C3291-2.048 meets the specific thermal requirements of the end application.

Q: What is the difference in frequency stability between these parts?

A: CE3290-2.048 provides ±100ppm frequency stability, while C3291-2.048 provides ±25ppm. The C3291-2.048 offers four times tighter stability, beneficial for timing-critical applications.

Q: Are the physical packages identical?

A: Yes. Both parts use 4-SMD, No Lead packages with identical dimensions (7.20mm x 5.20mm x 1.80mm max height) and surface mount mounting type, ensuring identical PCB footprints and assembly compatibility.

Q: Do both parts support enable/disable functionality?

A: Yes. Both CE3290-2.048 and C3291-2.048 include enable/disable function with identical 5V supply voltage and 60mA maximum current draw.

Q: Are there any compliance differences?

A: No. Both parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, REACH Unaffected status, and EAR99 ECCN classification.
