Substitute Part Grouping Explanation
Substitution eligibility for the ECS-200-20-1 is determined by strict equivalence across the following critical parameters:
- Frequency: 20 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)
Parts meeting all these criteria are classified as parametric equivalents and may be used as direct substitutes in applications originally designed for the ECS-200-20-1.

Engineering Selection Recommendations
The ECS-200-20-1X is a parametric equivalent substitute for the ECS-200-20-1. Both parts share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product lifecycle status: the ECS-200-20-1 is designated Not For New Designs, while the ECS-200-20-1X maintains Active status in the manufacturer's current product line.
An additional consideration is regulatory compliance. The ECS-200-20-1X is ROHS3 Compliant, whereas the ECS-200-20-1 is RoHS non-compliant. For applications subject to RoHS requirements, the ECS-200-20-1X is the appropriate selection. Both parts maintain identical REACH and ECCN classifications.
Frequently Asked Questions (FAQ)
Q: Can the ECS-200-20-1X be used as a direct replacement for the ECS-200-20-1?
A: Yes. The ECS-200-20-1X meets all electrical and mechanical parameter requirements for direct substitution. Both parts are manufactured by ECS Inc., share identical frequency, load capacitance, ESR, package type, and operating temperature specifications.
Q: What is the difference between these two part numbers?
