Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SG-615PCG are identified based on the following critical parameters that determine functional compatibility:

Primary Matching Criteria:

• Frequency: 20 MHz (exact match required)
• Package / Case: 4-SOJ, 5.08mm pitch (mechanical compatibility)
• Output Type: CMOS, TTL (signal compatibility)
• Function: Enable/Disable (operational feature)
• Operating Temperature: -40°C ~ 85°C (environmental range)
• Mounting Type: Surface Mount (assembly compatibility)

Secondary Compatibility Factors:

• Supply Voltage: Substitutes may operate at different voltage levels (3.3V or 5V) depending on circuit design requirements
• Frequency Stability: Tolerance variations (±100ppm vs ±200ppm) must be evaluated against application specifications
• Current consumption: Maximum supply current and disable current specifications must not exceed circuit design limits

The ECS-8FMX-200-TR meets all primary matching criteria and operates within the same temperature range and package specification, making it a valid substitute despite differences in supply voltage and frequency stability specifications.

Parameter Comparison

Engineering Selection Recommendations

The ECS-8FMX-200-TR is an active product with confirmed ROHS3 compliance and represents a viable substitute for the obsolete SG-615PCG. Both components share identical mechanical specifications, frequency output, and functional capabilities.

Voltage Consideration: The substitute operates at 5V supply voltage compared to the original 3.3V specification. Circuit design must accommodate this voltage difference through appropriate power supply configuration or voltage regulation.

Frequency Stability: The substitute exhibits ±200ppm stability versus the original ±100ppm specification. Applications requiring tighter frequency tolerance must evaluate whether this variance meets system requirements.

Current Consumption: The substitute draws 23mA maximum supply current, which is lower than the original 28mA specification, providing improved power efficiency.

Compliance Status: Both components maintain ROHS3 compliance and are suitable for applications subject to environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the ECS-8FMX-200-TR directly replace the SG-615PCG without circuit modifications?

A: Direct mechanical and functional replacement is possible due to identical package specifications and pin configuration. However, the 5V supply voltage requirement necessitates circuit design review to ensure power supply compatibility.

Q: What is the impact of the ±200ppm frequency stability on system performance?

A: Frequency stability tolerance depends on application requirements. Applications with strict frequency accuracy specifications must evaluate whether the doubled tolerance range (±200ppm vs ±100ppm) is acceptable for intended use.

Q: Are both components suitable for industrial temperature applications?

A: Yes. Both the SG-615PCG and ECS-8FMX-200-TR operate across the -40°C to 85°C temperature range, supporting industrial and extended commercial applications.

Q: What is the significance of the product status difference?

A: The SG-615PCG is classified as obsolete, indicating discontinued manufacturing and limited availability. The ECS-8FMX-200-TR maintains active product status with confirmed current inventory and ongoing manufacturer support.

Q: Are there packaging format differences between these components?

A: Both components are supplied in 4-SOJ surface mount packages with 5.08mm pitch and identical physical dimensions (14.00mm x 8.65mm x 4.70mm maximum height). The ECS-8FMX-200-TR is available in Tape & Reel (TR) packaging format.

Q: How do the current consumption specifications compare?

A: The ECS-8FMX-200-TR consumes 23mA maximum supply current, which is 5mA lower than the SG-615PCG specification of 28mA. This represents improved power efficiency in the substitute component.
