Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CE3392-50.000 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

• Frequency: 50 MHz (exact match required)
• Output Type: HCMOS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Package Type: 4-SMD, No Lead (exact match required)
• Mounting Type: Surface Mount (exact match required)
• RoHS3 Compliance: Required for regulatory equivalence
• Frequency Stability: ±50ppm or better
• Operating Temperature Range: -40°C ~ 85°C or wider
• Maximum Supply Current: 25mA or lower

All identified substitutes meet these core electrical and mechanical criteria, ensuring direct board-level compatibility without design modification.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status and full RoHS3 compliance, ensuring long-term availability and regulatory alignment with the CE3392-50.000.

The C3391-50.000 (Crystek Corporation) offers improved frequency stability at ±25ppm but operates within a narrower temperature range (0°C ~ 70°C). This part is suitable for applications where the operating environment remains within this temperature window and tighter frequency tolerance is beneficial.

The ECS-3953M-500-BN-TR (ECS Inc.) and LFSPXO019987 (IQD Frequency Products) both match the full electrical and temperature specifications of the CE3392-50.000, including the -40°C ~ 85°C operating range and ±50ppm frequency stability. Both are direct functional equivalents with identical supply current and package configuration.

Selection between these three substitutes depends on application temperature requirements, desired frequency stability, and supply chain availability. All maintain mechanical compatibility with existing PCB layouts designed for the CE3392-50.000.

Frequently Asked Questions (FAQ)

Q: Can the C3391-50.000 replace the CE3392-50.000 in all applications?

A: The C3391-50.000 is electrically compatible but operates within a narrower temperature range (0°C ~ 70°C versus -40°C ~ 85°C). It is suitable only for applications where the operating environment remains within 0°C to 70°C. Applications requiring the full -40°C ~ 85°C range must use ECS-3953M-500-BN-TR or LFSPXO019987.

Q: Are all substitute parts pin-compatible with the CE3392-50.000?

A: Yes. All substitute parts use the 4-SMD, No Lead package type with identical pinout and surface mount configuration, ensuring direct PCB compatibility without layout modification.

Q: What is the difference between the ECS-3953M-500-BN-TR and LFSPXO019987?

A: Both parts are electrically and functionally equivalent to the CE3392-50.000. The primary difference is physical height: ECS-3953M-500-BN-TR has a maximum seated height of 0.067" (1.70mm), while LFSPXO019987 has a maximum seated height of 0.055" (1.40mm). Selection depends on available PCB clearance and height constraints.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. All substitute parts listed are ROHS3 Compliant and REACH Unaffected, matching the regulatory status of the CE3392-50.000.

Q: What is the significance of Moisture Sensitivity Level (MSL) differences?

A: The CE3392-50.000, C3391-50.000, and ECS-3953M-500-BN-TR all have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The LFSPXO019987 lists MSL as Not Applicable, which also indicates no moisture-related handling constraints. All parts are equivalent in this regard.
