Engineering Selection Recommendations

The ECS-50-S-5PX-TR is the direct substitute for the ECS-50-S-5P-TR. All electrical and mechanical parameters are identical, ensuring pin-for-pin and functional compatibility in existing circuit designs.

The primary distinction is product lifecycle status: the original part is classified as Not For New Designs, while the substitute is Active. Additionally, the substitute achieves ROHS3 compliance, whereas the original is RoHS non-compliant. For applications requiring RoHS compliance or long-term supply assurance, the ECS-50-S-5PX-TR is the appropriate selection. For legacy system maintenance where the original part specification must be maintained, both parts are electrically and mechanically interchangeable.

Frequently Asked Questions (FAQ)

Q: Can ECS-50-S-5PX-TR replace ECS-50-S-5P-TR in existing designs?

A: Yes. All electrical parameters (frequency, tolerance, stability, ESR, operating mode) and mechanical parameters (package, dimensions, height, mounting type) are identical. Direct substitution is possible without circuit modification.

Q: What is the difference between these two parts?

A: The parts are electrically and mechanically equivalent. The ECS-50-S-5PX-TR represents an updated product line (CSM-7X series) with Active status and ROHS3 compliance, compared to the original CSM-7 series with Not For New Designs status and RoHS non-compliance.

Q: Are the physical footprints identical?

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

Q: Does the substitute part have the same frequency accuracy?

A: Yes. Both parts specify ±30ppm frequency tolerance and ±50ppm frequency stability. Frequency accuracy performance is identical.

Q: What is the ESR specification for both parts?

A: Both parts have 80 Ohms equivalent series resistance. Load capacitance configuration is series for both parts.

Q: Are there any compliance differences?

A: Yes. The ECS-50-S-5PX-TR is ROHS3 compliant, while the ECS-50-S-5P-TR is RoHS non-compliant. Both parts are REACH Unaffected and classified as EAR99 for export control purposes.

Q: What is the operating temperature range?

A: Both parts operate across -10°C to 70°C. Temperature performance specifications are identical.
