Parameter Comparison

Engineering Selection Recommendations

ECS-480-20-33-CKM-TR (Upgrade Substitute)

This part provides improved frequency stability at ±10ppm compared to the main part's ±50ppm specification. All mandatory electrical and mechanical parameters are identical. Both parts maintain identical operating temperature range (-20°C ~ 70°C), ROHS3 compliance, and MSL rating. Selection of this upgrade substitute is appropriate when tighter frequency tolerance is required by the application circuit.

ECS-480-20-33-DU-TR (Similar Substitute)

This part matches all mandatory electrical and mechanical parameters with the main part. The operating temperature range extends to -55°C ~ 125°C, providing broader environmental capability compared to the main part's -20°C ~ 70°C range. Frequency stability is ±100ppm. Both parts maintain ROHS3 compliance and MSL rating of 1. Selection of this similar substitute is appropriate for applications requiring extended temperature operation or when the broader temperature specification provides system-level benefits.

Frequently Asked Questions (FAQ)

Q: Can ECS-480-20-33-CKM-TR replace ECS-480-20-33-TR in existing designs?

A: Yes. The ECS-480-20-33-CKM-TR is electrically and mechanically compatible. It provides identical frequency, load capacitance, ESR, package dimensions, and operating temperature range. The improved frequency stability (±10ppm vs ±50ppm) does not prevent substitution and may benefit circuit performance.

Q: What is the primary difference between ECS-480-20-33-DU-TR and the main part?

A: The ECS-480-20-33-DU-TR extends the operating temperature range to -55°C ~ 125°C compared to -20°C ~ 70°C. All other electrical parameters and physical dimensions remain identical. Frequency stability is ±100ppm.

Q: Are all three parts in the same physical package?

A: Yes. All three parts use 4-SMD, No Lead package with identical dimensions of 0.126" L x 0.098" W (3.20mm x 2.50mm) and maximum seated height of 0.031" (0.80mm). They are mechanically interchangeable on PCB layouts.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry MSL rating of 1 (Unlimited). All are classified as Active status products from ECS Inc.

Q: Which substitute should be selected for high-temperature applications?

A: The ECS-480-20-33-DU-TR supports operating temperatures from -55°C to 125°C, making it suitable for extended temperature environments. The main part and ECS-480-20-33-CKM-TR are limited to -20°C ~ 70°C.
