Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following critical parameters: frequency (50 MHz), output type (CMOS or LVCMOS), supply voltage (3.3V), function (Enable/Disable), package type (4-SMD, No Lead), and physical dimensions (7.00mm x 5.00mm). Frequency stability, operating temperature range, and supply current specifications define performance boundaries within which substitutes remain functionally equivalent.

The FN5000113 accepts three substitute parts:

FN5000109: Upgrade option with improved frequency stability (±25ppm vs ±50ppm) and reduced disable current (10µA vs 100µA). Output type is LVCMOS instead of CMOS. Packaging is Tape & Reel.
FN5000110: Manufacturer-recommended substitute with extended operating temperature range (-40°C ~ 85°C vs -20°C ~ 70°C). Output type and electrical specifications match the main part. Packaging is Bulk.
SXO75C3A271-50.000M: Direct cross-reference from Suntsu Electronics with identical electrical specifications. Slightly reduced height (0.063" vs 0.071"). Packaging is Bulk.

Engineering Selection Recommendations

FN5000109 is suitable when improved frequency stability (±25ppm) and reduced quiescent disable current (10µA) are required. The LVCMOS output type provides lower voltage swing compared to standard CMOS. This part is supplied in Tape & Reel packaging.

FN5000110 is the manufacturer-recommended substitute when extended operating temperature range (-40°C ~ 85°C) is required for industrial or automotive applications. Electrical specifications and CMOS output match the main part. This part is supplied in Bulk packaging.

SXO75C3A271-50.000M is a direct cross-reference from Suntsu Electronics with identical electrical performance. The reduced package height (0.063" vs 0.071") may provide advantages in space-constrained designs. This part is supplied in Bulk packaging.

All substitute parts maintain ROHS3 compliance and Active product status.

Frequently Asked Questions (FAQ)

Q: Can FN5000109 replace FN5000113 in all applications? A: FN5000109 is electrically compatible with improved frequency stability and lower disable current. The LVCMOS output type differs from the CMOS output of FN5000113. Verify that the receiving circuit accepts LVCMOS signal levels before substitution.

Q: What is the primary advantage of FN5000110 over FN5000113? A: FN5000110 extends the operating temperature range to -40°C ~ 85°C, making it suitable for industrial and automotive environments. All other electrical specifications remain equivalent.

Q: Is SXO75C3A271-50.000M a direct replacement for FN5000113? A: Yes. SXO75C3A271-50.000M maintains identical frequency, output type, supply voltage, and electrical specifications. The reduced package height (0.063" vs 0.071") is the only physical difference.

Q: What packaging formats are available for these substitutes? A: FN5000113 and FN5000110 are supplied in Bulk packaging. FN5000109 is supplied in Tape & Reel (TR) packaging. SXO75C3A271-50.000M is supplied in Bulk packaging.

Q: Are all substitute parts ROHS3 compliant? A: Yes. FN5000113, FN5000109, FN5000110, and SXO75C3A271-50.000M are all ROHS3 compliant.

Q: What is the difference between CMOS and LVCMOS output types? A: LVCMOS (Low Voltage CMOS) produces lower voltage swing output signals compared to standard CMOS. Both are compatible with 3.3V supply voltage. Verify receiver circuit specifications before selecting LVCMOS output.
