A: Yes. ELXV101ETE101MK20S has a maximum seated height of 0.846" (21.50 mm) compared to 0.866" (22.00 mm) for UPS2A101MHD1TO. This 0.020" difference is within typical PCB design tolerances and does not affect functional compatibility.

Q: Which substitute offers the lowest impedance?

A: EKZE101ELL101MK16S offers the lowest impedance at 110 mOhms, followed by ELXV101ETE101MK20S at 150 mOhms. The original UPS2A101MHD1TO and UPW2A101MHD1TO both have 180 mOhms impedance.

Q: Can I use EKZE101ELL101MK16S in place of UPS2A101MHD1TO?

A: Yes. EKZE101ELL101MK16S meets all core electrical and mechanical requirements with identical capacitance, voltage rating, tolerance, package type, and lead spacing. The operating temperature range is -40°C to 105°C (versus -55°C to 105°C for the original), and the height is reduced to 0.689". Verify that the reduced minimum operating temperature (-40°C versus -55°C) is acceptable for your application.
