Substitute Part Grouping Explanation

Substitution eligibility for the ECS-200-18-9 is determined by strict equivalence across the following critical parameters:

• Frequency: 20 MHz (exact match required)
• Frequency Stability: ±50ppm (exact match required)
• Load Capacitance: 18pF (exact match required)
• ESR: 50 Ohms (exact match required)
• Operating Mode: Fundamental (exact match required)
• Operating Temperature Range: -10°C ~ 60°C (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Cylindrical Can, Radial (exact match required)
• Physical Dimensions: 0.126" Dia x 0.354" L (exact match required)

The ECS-200-18-9X meets all substitution criteria as a parametric equivalent with identical electrical specifications and mechanical form factor.
