Key Parameters

Substitute Part Grouping Explanation

Substitution of the FDC500017 is determined by strict equivalence in the following critical parameters:

• Frequency: 125 MHz (exact match required)
• Output Type: CMOS (exact match required)
• Supply Voltage: 2.5V (exact match required)
• Function: Enable/Disable (exact match required)
• Package / Case: 4-SMD, No Lead (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Physical Dimensions: 5.00mm x 3.20mm footprint and 1.30mm maximum height (exact match required)

The FDC500015 qualifies as a direct substitute based on identical values across all critical parameters. Variations in Frequency Stability and Operating Temperature range do not preclude substitution when these parameters fall within application requirements.

Parameter Comparison

Engineering Selection Recommendations

The FDC500015 is a qualified substitute for the FDC500017 in applications where the operating temperature range of -20°C to 70°C and frequency stability of ±25ppm are acceptable. Both parts maintain Active product status and full ROHS3 compliance with REACH Unaffected designation, ensuring regulatory alignment for current and future manufacturing requirements. Selection between these parts should be based on specific application temperature and frequency stability demands rather than electrical or mechanical incompatibility.

Frequently Asked Questions (FAQ)

Q: Can FDC500015 be used as a direct replacement for FDC500017 in all applications?

A: The FDC500015 is electrically and mechanically compatible with the FDC500017. However, application-specific requirements for operating temperature range (-20°C to 70°C vs. -40°C to 85°C) and frequency stability (±25ppm vs. ±50ppm) must be evaluated before substitution.

Q: Are the physical dimensions and mounting characteristics identical?

A: Yes. Both parts use identical 4-SMD, No Lead packaging with 5.00mm x 3.20mm footprint and 1.30mm maximum seated height, ensuring PCB layout and assembly compatibility without modification.

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

A: The FDC500017 specifies ±50ppm frequency stability, while the FDC500015 specifies ±25ppm. The FDC500015 provides tighter frequency tolerance. Selection depends on application clock accuracy requirements.

Q: Do both parts meet current regulatory compliance standards?

A: Yes. Both FDC500017 and FDC500015 are ROHS3 Compliant and REACH Unaffected, meeting current environmental and hazardous substance regulations.

Q: What is the operating temperature difference, and does it affect substitution?

A: The FDC500017 operates from -40°C to 85°C, while the FDC500015 operates from -20°C to 70°C. Substitution is valid only when the application's temperature environment falls within the -20°C to 70°C range.
