Key Parameters

Substitute Part Grouping Explanation

Substitution of the CS325-24.576MABJ-UT is determined by strict equivalence across the following critical parameters:

• Frequency: 24.576 MHz (exact match required)
• Frequency Tolerance: ±30ppm (defines acceptable frequency deviation)
• Load Capacitance: 18pF (determines circuit compatibility)
• ESR: 80 Ohms (affects oscillator startup and stability)
• Operating Mode: Fundamental (defines harmonic content)
• Package Type: 4-SMD, No Lead (ensures mechanical and electrical compatibility)
• Operating Temperature Range: -10°C to 60°C (defines environmental suitability)

The CS325S24576000ABJT meets all these parameters identically and qualifies as a parametric equivalent substitute.
