Parameter Comparison

Engineering Selection Recommendations

All three parts—ASV-10.000MHZ-LCS-T, ECS-3953M-100-BN-TR, and LFSPXO019928—are active production components with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component sourcing.

The ECS-3953M-100-BN-TR offers the highest inventory availability at 10,553 units and features a lower seated height of 0.067" (1.70mm) compared to the primary part. Maximum supply current is 15mA, which is 5mA higher than the ASV part.

The LFSPXO019928 from IQD Frequency Products provides the lowest maximum supply current at 7mA and the lowest seated height at 0.055" (1.40mm), making it suitable for power-constrained or space-limited applications. Inventory availability is 1,387 units.

Selection between these parts should be based on supply chain requirements, inventory availability, and application-specific constraints regarding power consumption and physical height clearance.

Frequently Asked Questions (FAQ)

Q: Can ECS-3953M-100-BN-TR be used as a direct replacement for ASV-10.000MHZ-LCS-T?

A: Yes. Both parts share identical electrical specifications: 10 MHz frequency, HCMOS output, 3.3V supply, enable/disable function, ±50ppm frequency stability, and -40°C to 85°C operating range. Physical dimensions are within acceptable tolerance for standard PCB layouts, with the ECS part being slightly smaller in length and width.

Q: What are the differences in power consumption between these parts?

A: The ASV-10.000MHZ-LCS-T draws a maximum of 10mA during operation. The ECS-3953M-100-BN-TR draws up to 15mA, while the LFSPXO019928 draws only 7mA. Applications with strict power budgets should prioritize the IQD part.

Q: Are there package compatibility concerns?

A: All three parts use 4-SMD, No Lead surface mount packages with identical pinout and function. Physical dimensions vary slightly: the ASV measures 7.00mm x 5.08mm, the ECS measures 7.00mm x 5.00mm, and the IQD measures 7.20mm x 5.20mm. These variations are within standard PCB design tolerances for 0.05" pitch component placement.

Q: Do all parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8542.39.0001.

Q: Which part should be selected for new designs?

A: Selection depends on supply chain strategy and application requirements. The ECS part offers maximum availability. The IQD part offers lowest power consumption and smallest height. The Abracon part is the original specification. All are functionally equivalent for the stated electrical and mechanical parameters.
