CE3392-20.000 Equivalent & Substitute Parts

Part Overview

The CE3392-20.000 is a 20 MHz XO (Standard) HCMOS oscillator manufactured by Crystek Corporation. 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 status and ROHS3 compliant, making it suitable for applications requiring stable frequency generation with low power consumption. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory constraints require component flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CE3392-20.000 are qualified based on the following critical parameters:

• Frequency: 20 MHz (exact match required)
• Output Type: HCMOS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Frequency Stability: ±50ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Package Type: 4-SMD, No Lead (exact match required)
• Mounting Type: Surface Mount (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

All identified substitute parts meet these electrical and mechanical specifications, ensuring functional and physical compatibility with the original CE3392-20.000 design.

Parameter Comparison

Engineering Selection Recommendations

All three oscillators are Active status products with ROHS3 compliance and REACH Unaffected designation, meeting current regulatory requirements for electronic component procurement.

The ECS-3953M-200-BN-TR offers reduced maximum supply current (15mA versus 18mA) and slightly smaller physical dimensions, providing potential benefits for power-constrained or space-limited applications while maintaining full electrical compatibility.

The LFSPXO019992 provides the lowest maximum supply current (12mA) and the lowest seated height (1.40mm), offering advantages for low-power designs and applications with strict height constraints. This part carries Not Applicable moisture sensitivity level classification.

Selection between substitute parts should be based on specific application requirements regarding power consumption, physical space constraints, and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can ECS-3953M-200-BN-TR be used as a direct replacement for CE3392-20.000?

A: Yes. Both parts share identical electrical specifications (20 MHz, HCMOS output, 3.3V supply, ±50ppm stability, -40°C to 85°C operating range, enable/disable function) and package type (4-SMD, No Lead). Physical dimensions differ slightly, but both are surface mount compatible.

Q: What are the key differences between the three oscillators?

A: All three meet the core electrical requirements. Primary differences are maximum supply current (CE3392-20.000: 18mA, ECS-3953M-200-BN-TR: 15mA, LFSPXO019992: 12mA) and physical dimensions. The LFSPXO019992 has the lowest height (1.40mm) and lowest power consumption.

Q: Are there any package compatibility concerns?

A: All three parts use 4-SMD, No Lead surface mount packages. While physical dimensions vary slightly, the packages are mechanically compatible with standard PCB footprints designed for this package type. Verify PCB layout clearances for height-sensitive applications.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, REACH Unaffected, and carry EAR99 ECCN classification. All are classified under HTSUS 8542.39.0001.

Q: Which substitute part should I select for power-sensitive applications?

A: The LFSPXO019992 offers the lowest maximum supply current at 12mA, making it the optimal choice for battery-powered or low-power designs.

Q: Which substitute part is best for space-constrained designs?

A: The LFSPXO019992 provides the lowest seated height at 1.40mm, followed by the ECS-3953M-200-BN-TR at 1.70mm, compared to the CE3392-20.000 at 1.80mm.
