The FN2400047 has three qualified substitutes: FN2400045 and FN2400046 from Diodes Incorporated, and SXO75C3C271-24.000M from Suntsu Electronics, Inc. All maintain identical electrical output characteristics and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with the FN2400047. Selection between substitutes depends on application-specific requirements:

FN2400045 provides extended operating temperature range (-40°C ~ 85°C) compared to the FN2400047 (-20°C ~ 70°C), suitable for applications requiring broader thermal performance. Frequency stability is ±50ppm.

FN2400046 matches the FN2400047 operating temperature range (-20°C ~ 70°C) with identical current specifications. Frequency stability is ±50ppm.

SXO75C3C271-24.000M from Suntsu Electronics offers equivalent frequency stability (±25ppm) to the FN2400047 with a lower seated height (0.063" versus 0.071"), beneficial for space-constrained designs. Maximum supply current is 16mA.

All four parts are electrically and mechanically interchangeable within the specified parameter tolerances.

Frequently Asked Questions (FAQ)

Q: Can FN2400045 replace FN2400047 in all applications? A: FN2400045 is electrically compatible. The primary difference is extended operating temperature range (-40°C ~ 85°C versus -20°C ~ 70°C) and relaxed frequency stability (±50ppm versus ±25ppm). Verify application temperature requirements before substitution.

Q: What is the difference between FN2400046 and FN2400047? A: Both parts share identical operating temperature range (-20°C ~ 70°C) and current specifications (15mA max). FN2400046 has ±50ppm frequency stability compared to FN2400047's ±25ppm. Both are mechanically and electrically compatible.

Q: Is SXO75C3C271-24.000M from a different manufacturer compatible? A: Yes. SXO75C3C271-24.000M from Suntsu Electronics maintains all critical electrical parameters and package specifications. The lower seated height (0.063" versus 0.071") may be advantageous in compact designs.

Q: Do all substitutes have the same package dimensions? A: All parts share identical length and width (0.276" L x 0.197" W / 7.00mm x 5.00mm). SXO75C3C271-24.000M has a lower maximum seated height (0.063" versus 0.071"), which may affect PCB layout in height-constrained applications.

Q: Are all parts ROHS3 compliant? A: Yes. FN2400047, FN2400045, FN2400046, and SXO75C3C271-24.000M are all ROHS3 compliant.

Q: What frequency stability should I select? A: FN2400047 and SXO75C3C271-24.000M offer ±25ppm stability. FN2400045 and FN2400046 offer ±50ppm stability. Select based on application timing accuracy requirements.
