Substitute Part Grouping Explanation

The FD2500050 is identified as a manufacturer-recommended substitute for the FD2500051. Both parts share identical core specifications across frequency, supply voltage, function, operating temperature range, current consumption, mounting type, package form factor, and compliance certifications. The primary distinction lies in the output logic type: FD2500051 provides CMOS output, while FD2500050 provides LVCMOS output. This substitution is valid when the receiving circuit is compatible with LVCMOS signal levels, which are a subset of CMOS specifications. Both parts maintain the same physical footprint and thermal characteristics, enabling direct board-level substitution without layout modifications.

Parameter Comparison

Engineering Selection Recommendations

Both FD2500051 and FD2500050 are Active status products from Diodes Incorporated with full ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance for industrial and commercial applications. The selection between these parts depends on output logic compatibility: FD2500051 with CMOS output is suitable for circuits requiring standard CMOS signal levels, while FD2500050 with LVCMOS output is appropriate for low-voltage CMOS compatible receivers. The FD2500051 offers tighter frequency stability at ±20ppm compared to FD2500050 at ±50ppm, a factor relevant to applications with stringent timing requirements. Both parts share identical physical dimensions and thermal characteristics, supporting direct substitution at the board level when output logic compatibility is confirmed.

Frequently Asked Questions (FAQ)

Q: Can FD2500050 directly replace FD2500051 in my circuit? A: Direct substitution is possible if your receiving circuit accepts LVCMOS input levels. LVCMOS is a low-voltage variant of CMOS and operates within compatible signal ranges for most CMOS-compatible receivers. Verify your circuit's input specifications before substitution.

Q: What is the difference between CMOS and LVCMOS output? A: CMOS and LVCMOS both provide digital logic outputs at 2.5V supply. LVCMOS is optimized for lower voltage operation and reduced power consumption. Both are compatible with standard logic receivers designed for 2.5V operation.

Q: Does the frequency stability difference affect substitution? A: FD2500051 provides ±20ppm stability while FD2500050 provides ±50ppm. Applications requiring tighter frequency tolerance should use FD2500051. Applications with relaxed timing requirements can use FD2500050.

Q: Are the physical dimensions identical? A: Both parts use 4-SMD, No Lead packaging with identical length and width (5.00mm x 3.20mm). Maximum seated height differs slightly: FD2500051 at 1.30mm and FD2500050 at 1.35mm. This minimal difference does not affect PCB layout or assembly compatibility.

Q: What compliance certifications apply to both parts? A: Both FD2500051 and FD2500050 are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for industrial and commercial electronics applications.
