Substitute Part Grouping Explanation

Substitution between ECS-480-20-5PX-TR and ECS-480-20-5P-TR is based on the following allowed parameters:

• Frequency: Both parts operate at 48 MHz
• Frequency Tolerance: Both maintain ±30ppm tolerance
• Load Capacitance: Both specify 20pF
• ESR: Both have 80 Ohms equivalent series resistance
• Operating Mode: Both use 3rd Overtone mode
• Operating Temperature: Both support -10°C ~ 70°C range
• Package / Case: Both use HC-49/US package
• Mounting Type: Both are surface mount
• MSL Rating: Both have MSL 1 (Unlimited)

The primary differences are packaging format (Cut Tape vs. Tape & Reel) and compliance certifications, which do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

ECS-480-20-5PX-TR is the primary selection for new designs. This part carries Active product status, ensuring long-term availability and manufacturer support. It is RoHS3 compliant, meeting current environmental and regulatory requirements for commercial and industrial applications.

ECS-480-20-5P-TR is electrically and mechanically equivalent but is designated as Not For New Designs and is RoHS non-compliant. This part may be considered only for legacy system maintenance or replacement scenarios where existing inventory constraints require substitution. The Cut Tape packaging of the primary part is suitable for lower-volume applications, while the Tape & Reel format of the substitute supports higher-volume production runs.

Frequently Asked Questions (FAQ)

Q: Are ECS-480-20-5PX-TR and ECS-480-20-5P-TR electrically interchangeable?

A: Yes. Both parts operate at 48 MHz with ±30ppm frequency tolerance, 20pF load capacitance, and 80 Ohms ESR. They are functionally equivalent in circuit applications.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) packaging is supplied in individual strips suitable for lower-volume or manual assembly. Tape & Reel (TR) packaging is supplied on continuous reels for automated pick-and-place assembly in high-volume production. Both formats contain the same component in the same HC-49/US package.

Q: Why is ECS-480-20-5P-TR marked as Not For New Designs?

A: This designation indicates the manufacturer is phasing out this part number. New designs should use ECS-480-20-5PX-TR to ensure long-term availability and support.

Q: Does RoHS compliance affect circuit performance?

A: RoHS compliance relates to material composition and environmental standards, not electrical performance. Both parts meet the same electrical specifications. However, RoHS3 compliance of ECS-480-20-5PX-TR is required for applications subject to current environmental regulations.

Q: Can I use ECS-480-20-5P-TR in a new product design?

A: Not recommended. The Not For New Designs status and RoHS non-compliance make ECS-480-20-5PX-TR the appropriate choice for new product development.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the HC-49/US package with identical dimensions: 0.449" L x 0.189" W (11.40mm x 4.80mm) and maximum seated height of 0.169" (4.30mm).
