Substitute Part Grouping Explanation

Substitution eligibility for the ECS-.320-12.5-13 is determined by strict equivalence across the following critical parameters:

• Frequency: 32 kHz (exact match required)
• Frequency Tolerance: ±30ppm (exact match required)
• Load Capacitance: 12.5pF (exact match required)
• Operating Mode: Fundamental (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Cylindrical Can, Radial (exact match required)
• Physical Dimensions: 0.083" Dia x 0.244" L / 2.10mm x 6.20mm (exact match required)
• Operating Temperature Range: -10°C ~ 60°C (exact match required)

The ECS-.320-12.5-13X meets all substitution criteria and is therefore a direct equivalent for this application.
