Substitute Part Grouping Explanation

Substitution eligibility for the FN6250029 is determined by strict equivalence across the following critical parameters:

• Frequency: Must be exactly 62.5 MHz
• Output Configuration: Must be CMOS
• Supply Voltage: Must be 3.3V
• Enable/Disable Function: Must be present
• Package Type: Must be 4-SMD, No Lead
• Physical Dimensions: Must be 7.00mm x 5.00mm with maximum height of 1.80mm
• Frequency Stability: Must meet ±50ppm specification
• Supply Current: Must not exceed 40mA
• Disable Current: Must not exceed 100µA

The FN6250027 qualifies as a direct substitute based on matching all electrical specifications and physical package requirements. Differences in operating temperature range do not affect substitution eligibility for this oscillator category.

Parameter Comparison

Engineering Selection Recommendations

The FN6250027 is a qualified substitute for the FN6250029 based on electrical and mechanical parameter equivalence. Both parts are manufactured by Diodes Incorporated, carry Active product status, and maintain full RoHS3 compliance with unlimited moisture sensitivity rating (MSL 1).

The operating temperature range difference (-40°C ~ 85°C for FN6250029 versus -20°C ~ 70°C for FN6250027) represents a specification variance that does not affect substitution eligibility when the application environment falls within the FN6250027 operating window. Design engineers must confirm that the narrower temperature range of the FN6250027 is acceptable for the intended application before component selection.

Both parts share identical electrical performance characteristics, package configuration, and compliance certifications, ensuring direct functional interchangeability in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can FN6250027 replace FN6250029 in existing designs?

A: Yes, the FN6250027 is electrically and mechanically equivalent to the FN6250029. Both parts deliver identical frequency output (62.5 MHz), supply voltage (3.3V), current characteristics, and package dimensions. The primary consideration is the operating temperature range: FN6250027 operates from -20°C to 70°C, while FN6250029 operates from -40°C to 85°C. Substitution is valid when the application environment remains within the FN6250027 temperature specification.

Q: Are the package dimensions identical?

A: Yes. Both the FN6250029 and FN6250027 use the same 4-SMD, No Lead package with dimensions of 7.00mm x 5.00mm and a maximum seated height of 1.80mm. PCB layout and reflow profiles remain unchanged during substitution.

Q: Do both parts have the same enable/disable functionality?

A: Yes. Both parts feature enable/disable control with identical supply current (40mA maximum) and disable current (100µA maximum) specifications.

Q: What compliance certifications apply to both parts?

A: Both the FN6250029 and FN6250027 are RoHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. ECCN classification is EAR99 for both parts.

Q: Are there any frequency or stability differences?

A: No. Both parts operate at 62.5 MHz with ±50ppm frequency stability and CMOS output configuration.
