Engineering Selection Recommendations

Both the ASDAIG-26.000MHZ-X-K-T and ECS-2520Q-33-260-DP-TR are active production components with identical electrical and mechanical specifications. Both components carry AEC-Q200 automotive-grade ratings and ROHS3 compliance certification. The ECS-2520Q-33-260-DP-TR offers higher inventory availability (3088 pieces versus 650 pieces) and a marginally lower seated height (0.90mm versus 0.95mm), which may provide advantages in space-constrained applications. Selection between these parts should be based on supply chain availability, lead time requirements, and design margin considerations for the seated height differential.

Frequently Asked Questions (FAQ)

Q: Can the ECS-2520Q-33-260-DP-TR be used as a direct replacement for the ASDAIG-26.000MHZ-X-K-T?

A: Yes. Both components share identical electrical specifications (26 MHz frequency, 3.3V supply, HCMOS output, ±30ppm stability, 7mA maximum supply current), identical mechanical package (4-SMD, No Lead, 2.50mm x 2.00mm), and identical functional characteristics (Enable/Disable capability). Both are AEC-Q200 rated and ROHS3 compliant.

Q: Are there any physical differences between these parts?

A: The seated height differs slightly: the ASDAIG-26.000MHZ-X-K-T has a maximum seated height of 0.95mm, while the ECS-2520Q-33-260-DP-TR has a maximum seated height of 0.90mm. This 0.05mm difference is negligible for most applications but should be verified if the design has tight vertical clearance constraints.

Q: Do both parts support enable/disable functionality?

A: Yes. Both the ASDAIG-26.000MHZ-X-K-T and ECS-2520Q-33-260-DP-TR include enable/disable functionality as specified in their product descriptions.

Q: Are both parts suitable for automotive applications?

A: Yes. Both components carry AEC-Q200 automotive-grade ratings, confirming suitability for automotive-grade reliability requirements.

Q: What is the frequency stability specification for both parts?

A: Both parts specify ±30ppm frequency stability across the operating temperature range of -40°C to 105°C.

Q: Are both parts RoHS compliant?

A: Yes. Both the ASDAIG-26.000MHZ-X-K-T and ECS-2520Q-33-260-DP-TR are ROHS3 compliant.
