Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN5000118 is determined by the following critical parameters:

• Frequency: Must be 50 MHz
• Supply Voltage: Must be 3.3V
• Package / Case: Must be 4-SMD, No Lead
• Function: Must support Enable/Disable
• Output Type: CMOS or LVCMOS (compatible logic families)
• Operating Temperature Range: Must encompass or match the application requirement
• Frequency Stability: ±25ppm or better (lower tolerance values are acceptable)
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: MSL 1 (Unlimited)

The following parts meet these criteria and are qualified substitutes:

• FN5000109 (Diodes Incorporated): LVCMOS output variant with identical frequency, voltage, and package specifications. Operating temperature range is -20°C ~ 70°C.
• FN5000110 (Diodes Incorporated): CMOS output variant with identical frequency, voltage, and package specifications. Frequency stability is ±50ppm (wider tolerance).
• SXO75C3C481-50.000M (Suntsu Electronics, Inc.): CMOS output variant with identical frequency, voltage, and package specifications. Height is 0.063" (1.60mm), which is lower than the main part.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement.

FN5000109 is suitable for applications where LVCMOS output is acceptable and operating temperature does not exceed 70°C. This part offers the same frequency stability as the main part (±25ppm) and identical supply voltage and package specifications.

FN5000110 is suitable for applications where CMOS output is required and operating temperature range matches the main part (-40°C ~ 85°C). This part has a wider frequency stability tolerance (±50ppm) compared to the main part.

SXO75C3C481-50.000M is suitable for applications where a lower profile component is beneficial. This part offers identical frequency stability (±25ppm), CMOS output, and full operating temperature range (-40°C ~ 85°C). The seated height is 0.063" (1.60mm), compared to 0.071" (1.80mm) for the main part.

Frequently Asked Questions (FAQ)

Q: Can FN5000109 replace FN5000118 in all applications?

A: FN5000109 is a direct substitute if the application accepts LVCMOS output logic levels and operates within the temperature range of -20°C ~ 70°C. If the application requires full -40°C ~ 85°C operation or CMOS-specific output characteristics, FN5000109 is not suitable.

Q: What is the difference between CMOS and LVCMOS output on these oscillators?

A: LVCMOS (Low Voltage CMOS) operates at lower voltage levels than standard CMOS. Both are compatible with 3.3V supply, but LVCMOS has different output swing characteristics. Verify receiver input specifications before substituting.

Q: Is FN5000110 a direct replacement for FN5000118?

A: FN5000110 is mechanically and electrically compatible with FN5000118 for CMOS output applications. The frequency stability tolerance is wider (±50ppm vs. ±25ppm). If the application requires ±25ppm stability, FN5000110 may not meet specifications.

Q: Can SXO75C3C481-50.000M be used in space-constrained designs?

A: Yes. SXO75C3C481-50.000M has a lower seated height of 0.063" (1.60mm) compared to 0.071" (1.80mm) for FN5000118, making it suitable for applications with height restrictions. All other mechanical and electrical parameters are compatible.

Q: Are all substitute parts available in the same packaging options?

A: FN5000118 and FN5000110 are available in Bulk packaging. FN5000109 is available in Tape & Reel (TR) packaging. SXO75C3C481-50.000M is available in Bulk packaging. Packaging format may affect procurement and handling procedures.

Q: Do all parts meet the same compliance standards?

A: Yes. All listed parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.
