Substitute Part Grouping Explanation

Substitution eligibility for the ECS-40-18-10 is determined by strict equivalence across the following critical parameters:

• Frequency: 4 MHz (exact match required)
• Frequency Stability: ±50ppm (exact match required)
• Load Capacitance: 18pF (exact match required)
• ESR: 150 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 0.413" L (exact match required)

The ECS-40-18-10X meets all substitution criteria as a parametric equivalent. Both parts share identical electrical specifications, mechanical dimensions, and functional characteristics. The primary distinction lies in product status and compliance certifications.
