Substitute Part Grouping Explanation

Substitution eligibility for the ECS-240-20-1 is determined by strict equivalence across the following critical parameters:

• Frequency: 24 MHz (exact match required)
• Frequency Tolerance: ±30ppm (exact match required)
• Load Capacitance: 20pF (exact match required)
• ESR: 20 Ohms (exact match required)
• Operating Mode: Fundamental (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 (exact match required)

The ECS-240-20-1X meets all substitution criteria as a parametric equivalent with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The ECS-240-20-1X is a direct parametric equivalent to the ECS-240-20-1. Both parts are active products from ECS Inc. with identical electrical and mechanical specifications. The primary distinction is RoHS compliance status: the ECS-240-20-1X is ROHS3 compliant, while the ECS-240-20-1 is RoHS non-compliant. Selection between these parts should be based on regulatory requirements and compliance mandates applicable to the end application. Both parts maintain equivalent moisture sensitivity levels and export classifications.

Frequently Asked Questions (FAQ)

Q: Can ECS-240-20-1X be used as a direct replacement for ECS-240-20-1?
