Substitute Part Grouping Explanation

Substitution for the ECS-110.5-32-1 is determined by strict equivalence across the following critical parameters:

  • Frequency: 11.0592 MHz (exact match required)
  • Load Capacitance: 32pF (exact match required)
  • ESR: 30 Ohms (exact match required)
  • Package / Case: HC-49/U (exact match required)
  • Mounting Type: Through Hole (exact match required)
  • Operating Temperature Range: -10°C ~ 70°C (minimum required)
  • Operating Mode: Fundamental (exact match required)

The substitute part ECS-110.5-32-1X meets all these criteria and is therefore a direct parametric equivalent suitable for replacement in applications requiring the ECS-110.5-32-1.
