Substitute Part Grouping Explanation

Substitution of the ECS-480-20-5P-TR is determined by strict equivalence across the following critical parameters:

• Frequency: 48 MHz (exact match required)
• Frequency Tolerance: ±30ppm (exact match required)
• Load Capacitance: 20pF (exact match required)
• ESR: 80 Ohms (exact match required)
• Operating Mode: 3rd Overtone (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)
• Physical Dimensions: 0.449" L x 0.189" W, Height 0.169" max (exact match required)

The ECS-480-20-5PX-TR meets all substitution criteria as a parametric equivalent. The primary distinction between these parts is packaging format and product lifecycle status.

Engineering Selection Recommendations

The ECS-480-20-5PX-TR is the direct parametric equivalent for the ECS-480-20-5P-TR. Selection between these parts should be based on the following factors:

Product Lifecycle Status: The ECS-480-20-5P-TR carries a Not For New Designs designation, indicating end-of-life trajectory. The ECS-480-20-5PX-TR maintains Active status, making it the appropriate choice for new circuit designs and long-term production planning.

Regulatory Compliance: The ECS-480-20-5PX-TR is ROHS3 compliant, whereas the main part is RoHS non-compliant. Applications subject to RoHS requirements must use the substitute part.

Packaging Considerations: The main part is supplied in Tape & Reel (TR) format, while the substitute is available in Cut Tape (CT) format. Packaging selection depends on assembly equipment capabilities and order quantity requirements.

Electrical Performance: Both parts are electrically identical across all specified parameters, ensuring direct functional substitution without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the ECS-480-20-5PX-TR be used as a direct replacement for the ECS-480-20-5P-TR?

A: Yes. The ECS-480-20-5PX-TR is a parametric equivalent with identical electrical specifications, physical dimensions, and performance characteristics. No circuit modifications are required.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging supplies components on continuous tape wound on reels, suitable for high-volume automated assembly. Cut Tape packaging provides components on tape segments, typically used for lower volumes or manual assembly processes. Both formats contain the same component.

Q: Why is the main part marked as Not For New Designs?

A: This designation indicates the part is in end-of-life phase. Manufacturers apply this status when transitioning to newer product lines. New designs should specify the active equivalent, ECS-480-20-5PX-TR.

Q: Are there any performance differences between these parts?

A: No. Both parts meet identical electrical and mechanical specifications for frequency, tolerance, load capacitance, ESR, operating temperature, and physical dimensions.

Q: Does RoHS compliance affect electrical performance?

A: RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both parts function identically in circuit applications. RoHS3 compliance of the substitute part ensures regulatory alignment for applications in restricted markets.

Q: What is the significance of the series designation change from CSM-7 to CSM-7X?

A: The series designation reflects the product line evolution. The CSM-7X series represents the current active generation with equivalent electrical performance to the legacy CSM-7 series.
