Key Parameters

Substitute Part Grouping Explanation

The LFSPXO020502 from IQD Frequency Products qualifies as a direct substitute for the CE3292-4.000 based on the following critical parameters:

• Identical frequency: 4.0000 MHz
• Matching output configuration: HCMOS, TTL
• Identical supply voltage: 5V
• Identical function: Enable/Disable
• Matching frequency stability: ±50ppm
• Identical operating temperature range: -40°C to 85°C
• Identical package type: 4-SMD, No Lead
• Identical package dimensions: 7.20mm L × 5.20mm W
• Equivalent compliance: ROHS3 Compliant, REACH Unaffected

Substitution is valid when these core electrical and mechanical parameters align. The LFSPXO020502 meets all specified criteria for direct replacement in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the CE3292-4.000 and LFSPXO020502 are active production parts with equivalent regulatory compliance. Selection between these parts should be based on:

• Supply chain availability and lead time requirements
• Current consumption constraints: The LFSPXO020502 operates at 20mA maximum supply current compared to 60mA for the CE3292-4.000, providing lower power consumption in applications where this is a design consideration
• Physical height clearance: The LFSPXO020502 has a maximum seated height of 1.40mm versus 1.80mm for the CE3292-4.000, relevant for space-constrained PCB layouts
• Moisture sensitivity handling: The CE3292-4.000 specifies MSL 1 (Unlimited), while the LFSPXO020502 lists MSL as Not Applicable, affecting storage and handling protocols

Both parts maintain ROHS3 compliance and REACH Unaffected status, suitable for applications with environmental regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the LFSPXO020502 directly replace the CE3292-4.000 in existing designs?

A: Yes. The LFSPXO020502 meets all critical electrical and mechanical specifications: identical 4 MHz frequency, HCMOS/TTL output, 5V supply, enable/disable function, ±50ppm stability, and -40°C to 85°C operating range. The 4-SMD, No Lead package with matching 7.20mm × 5.20mm dimensions ensures PCB footprint compatibility.

Q: What are the differences between these parts?

A: The primary differences are maximum supply current (20mA for LFSPXO020502 versus 60mA for CE3292-4.000), maximum seated height (1.40mm versus 1.80mm), and moisture sensitivity level designation. These differences do not affect functional compatibility in standard applications.

Q: Are both parts compliant with environmental regulations?

A: Yes. Both the CE3292-4.000 and LFSPXO020502 are ROHS3 Compliant and REACH Unaffected, meeting current environmental standards for electronic components.

Q: Which part should be selected for power-sensitive applications?

A: The LFSPXO020502 is preferable for applications where supply current minimization is required, as it operates at a maximum of 20mA compared to 60mA for the CE3292-4.000.

Q: Are there any package or mounting considerations?

A: Both parts use identical 4-SMD, No Lead surface mount packages with matching footprints. The LFSPXO020502 has a lower maximum seated height (1.40mm), which may be advantageous in space-constrained designs. Moisture sensitivity handling differs: the CE3292-4.000 requires MSL 1 precautions, while the LFSPXO020502 lists MSL as Not Applicable.
