FN2400046 Equivalent & Substitute Parts

Part Overview

The FN2400046 is a 24 MHz crystal oscillator manufactured by Diodes Incorporated, part of the SaRonix-eCera™ FN series. This CMOS oscillator operates at 3.3V with enable/disable functionality and is housed in a 4-SMD, No Lead package. The device is actively produced and ROHS3 compliant, making it suitable for modern electronic applications requiring precise frequency generation. Identifying equivalent and substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and optimize component sourcing across manufacturing environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN2400046 is determined by the following critical parameters: frequency (24 MHz), output type (CMOS), supply voltage (3.3V), enable/disable function, package type (4-SMD, No Lead), and physical dimensions (7.00mm x 5.00mm). Parts meeting these core specifications are considered direct substitutes. Frequency stability (±50ppm) and compliance certifications (ROHS3, REACH Unaffected) further validate substitution suitability. Operating temperature range variations do not preclude substitution when the application operates within the overlapping temperature window. Current consumption specifications must remain within or below the stated maximum values to ensure circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both FN2400045 (Diodes Incorporated) and SXO75C3A271-24.000M (Suntsu Electronics) are valid substitutes for the FN2400046 based on electrical and mechanical compatibility. All three parts share identical frequency, output type, supply voltage, function, frequency stability, and package dimensions. All parts maintain ROHS3 compliance and active product status.

The FN2400045 offers an extended operating temperature range (-40°C ~ 85°C) compared to the FN2400046 (-20°C ~ 70°C), providing broader environmental coverage for applications requiring wider temperature operation. The SXO75C3A271-24.000M features a reduced maximum height (1.60mm versus 1.80mm), which may be advantageous for space-constrained designs. The SXO75C3A271-24.000M maximum supply current is specified at 16mA, marginally higher than the 15mA specification of the Diodes parts, remaining within acceptable circuit design tolerances.

Selection between substitutes should be based on application-specific requirements: temperature range demands, physical height constraints, and supply chain availability. All three parts are suitable for direct substitution in circuits designed for the FN2400046 specification.

Frequently Asked Questions (FAQ)

Q: Can FN2400045 replace FN2400046 in existing designs? A: Yes. Both parts share identical frequency (24 MHz), output type (CMOS), supply voltage (3.3V), enable/disable function, frequency stability (±50ppm), and package dimensions (7.00mm x 5.00mm). The FN2400045 features an extended operating temperature range (-40°C ~ 85°C versus -20°C ~ 70°C), making it suitable for applications requiring broader temperature coverage.

Q: Is the SXO75C3A271-24.000M from Suntsu Electronics compatible with FN2400046 designs? A: Yes. The SXO75C3A271-24.000M meets all critical electrical specifications: 24 MHz frequency, CMOS output, 3.3V supply, enable/disable function, ±50ppm stability, and 4-SMD No Lead package with 7.00mm x 5.00mm dimensions. The reduced maximum height (1.60mm) and marginally higher supply current (16mA) do not preclude substitution in standard applications.

Q: What are the key parameters that determine substitution compatibility? A: Substitution compatibility is determined by: frequency (24 MHz), output type (CMOS), supply voltage (3.3V), enable/disable function, frequency stability (±50ppm), package type (4-SMD, No Lead), and package dimensions (7.00mm x 5.00mm). Operating temperature range, maximum supply current, and physical height may vary within acceptable engineering tolerances.

Q: Does operating temperature range affect substitution decisions? A: Operating temperature range does not preclude substitution if the application operates within the overlapping temperature window. The FN2400046 operates -20°C ~ 70°C, while FN2400045 operates -40°C ~ 85°C. Applications requiring operation below -20°C or above 70°C should specify FN2400045. Applications within -20°C ~ 70°C may use either part.

Q: Are all substitute parts ROHS3 compliant? A: Yes. FN2400046, FN2400045, and SXO75C3A271-24.000M are all ROHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the impact of the 1mA current difference between FN2400046 and SXO75C3A271-24.000M? A: The SXO75C3A271-24.000M specifies 16mA maximum supply current versus 15mA for FN2400046. This 1mA difference is negligible in most circuit applications and does not constitute a substitution barrier. Circuit design should accommodate the higher specification to ensure reliable operation.
