Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FN2000118 are identified based on strict electrical and mechanical compatibility criteria. The following parameters must match or be compatible:

• Frequency: 20 MHz (exact match required)
• Output Type: CMOS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Package / Case: 4-SMD, No Lead (exact match required)
• Physical Dimensions: 7.00mm x 5.00mm footprint (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match or wider range acceptable)
• RoHS Compliance: ROHS3 Compliant (exact match required)

Parameters that may vary within acceptable tolerances include frequency stability, maximum supply current, and seated height, provided the substitute part maintains functional equivalence and PCB compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts are actively produced and ROHS3 compliant, meeting current regulatory requirements for electronic component manufacturing and use.

FN2000115 (Upgrade Substitute): This Diodes Incorporated part offers improved frequency stability at ±25ppm compared to the FN2000118's ±50ppm specification. It maintains identical electrical and mechanical characteristics, making it a direct upgrade option for applications requiring tighter frequency tolerance. Both parts are from the same manufacturer and series.

SXO75C3A481-20.000M (Direct Substitute): This Suntsu Electronics part provides functional equivalence with identical frequency, output type, supply voltage, function, and package specifications. The maximum supply current is 16mA versus 15mA for the FN2000118, and the seated height is 1.60mm versus 1.80mm. These variations remain within acceptable mechanical and electrical tolerances for PCB integration. This part offers the highest inventory availability among the three options.

Selection between these parts should be based on manufacturer preference, supply chain availability, and specific application requirements regarding frequency stability and current consumption.

Frequently Asked Questions (FAQ)

Q: Can FN2000115 be used as a direct replacement for FN2000118?

A: Yes. FN2000115 is electrically and mechanically compatible with FN2000118. Both parts share identical frequency, output type, supply voltage, function, package, and physical dimensions. FN2000115 offers superior frequency stability (±25ppm vs. ±50ppm).

Q: Is SXO75C3A481-20.000M compatible with FN2000118 in the same PCB layout?

A: Yes. SXO75C3A481-20.000M matches all critical electrical and mechanical parameters. The seated height difference (1.60mm vs. 1.80mm) is within acceptable tolerance for standard PCB assembly processes and does not affect electrical performance or signal integrity.

Q: What are the key parameters that determine substitutability?

A: Frequency (20 MHz), output type (CMOS), supply voltage (3.3V), enable/disable function, 4-SMD No Lead package, 7.00mm x 5.00mm footprint, and -40°C to 85°C operating temperature range must all match exactly. Frequency stability, maximum supply current, and seated height may vary within acceptable tolerances.

Q: Are all three parts ROHS3 compliant?

A: Yes. FN2000118, FN2000115, and SXO75C3A481-20.000M are all ROHS3 compliant, meeting current environmental and regulatory standards.

Q: Which part should I select for new designs?

A: Selection depends on manufacturer preference, supply availability, and application requirements. FN2000115 is recommended if tighter frequency stability is required. SXO75C3A481-20.000M offers high availability and functional equivalence. Consult your supply chain and design specifications to determine the optimal choice.
