Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FD5000032 are classified based on strict electrical and mechanical compatibility. The primary substitution criteria are:

Critical Parameters (Must Match):

• Frequency: 50 MHz
• Output Type: CMOS
• Supply Voltage: 3.3V
• Function: Enable/Disable
• Package / Case: 4-SMD, No Lead
• Mounting Type: Surface Mount
• Operating Temperature Range: -20°C ~ 70°C
• Current - Supply (Max): 25mA

Allowable Variation Parameters:

• Frequency Stability: ±50ppm to ±25ppm (tighter tolerance acceptable)
• Height - Seated (Max): 0.051" to 0.055" (within assembly clearance limits)
• Current - Supply (Disable) (Max): 10µA or unspecified

The FD5000032 has two identified substitutes: FD5000033 (Diodes Incorporated) and SXO53C3A271-50.000M (Suntsu Electronics, Inc.). Both maintain all critical parameters while offering improved or equivalent performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

FD5000033 (Diodes Incorporated): This part is a direct upgrade within the same manufacturer's product line. It maintains identical mechanical and electrical specifications to the FD5000032 while offering improved frequency stability (±25ppm versus ±50ppm). Both parts are Active status with ROHS3 compliance. Selection of FD5000033 is appropriate when tighter frequency tolerance is required without any design modifications.

SXO53C3A271-50.000M (Suntsu Electronics, Inc.): This cross-manufacturer substitute maintains all critical electrical parameters and package dimensions. The maximum seated height is 0.055" (1.40mm) compared to 0.051" (1.30mm) for the FD5000032, representing a 0.10mm increase. This part is suitable for applications where cross-manufacturer sourcing is acceptable and assembly clearance accommodates the minor height difference. ROHS3 compliance and Active product status are maintained.

Frequently Asked Questions (FAQ)

Q: Can FD5000033 be used as a direct replacement for FD5000032? A: Yes. FD5000033 maintains identical electrical and mechanical specifications with improved frequency stability. No circuit modifications are required.

Q: What is the key difference between FD5000032 and FD5000033? A: Frequency stability is the primary difference. FD5000033 offers ±25ppm stability compared to ±50ppm for FD5000032. Both operate identically in all other parameters.

Q: Can SXO53C3A271-50.000M replace FD5000032 in all applications? A: SXO53C3A271-50.000M is electrically compatible and maintains the same frequency, voltage, and output characteristics. The seated height is 0.10mm taller (1.40mm versus 1.30mm). Verify PCB assembly clearance before substitution.

Q: Are all three parts ROHS3 compliant? A: Yes. FD5000032, FD5000033, and SXO53C3A271-50.000M are all ROHS3 compliant.

Q: What is the significance of the 4-SMD, No Lead package? A: This package type indicates a surface mount oscillator with four solder pads and no through-hole leads. All three parts use identical package geometry (5.00mm x 3.20mm), ensuring PCB footprint compatibility.

Q: Does frequency stability affect circuit performance? A: Frequency stability determines long-term frequency accuracy. FD5000033 with ±25ppm provides tighter tolerance than FD5000032 at ±50ppm. Selection depends on application frequency accuracy requirements.

Q: Are there inventory considerations for part selection? A: FD5000032 has 1003 units in stock, FD5000033 has 734 units, and SXO53C3A271-50.000M has 6227 units available. Availability may influence sourcing decisions.
