Substitute Part Grouping Explanation

Substitution for the ECS-61-32-5P-TR is determined by strict equivalence across the following critical parameters:

• Frequency: 6.144 MHz (exact match required)
• Frequency Tolerance: ±30ppm (exact match required)
• Load Capacitance: 32pF (exact match required)
• ESR: 70 Ohms (exact match required)
• Package / Case: HC-49/US (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -10°C ~ 70°C (exact match required)
• Operating Mode: Fundamental (exact match required)

The substitute part ECS-61-32-5PX-TR meets all these criteria and is therefore a direct parametric equivalent.

Parameter Comparison
