Frequently Asked Questions (FAQ)

Q: Can UVK2G2R2MPD be replaced with ULD2G2R2MPD? A: Yes. Both parts share identical electrical specifications (2.2 µF, 400 V, ±20%) and physical dimensions (0.138" lead spacing, 0.315" diameter). ULD2G2R2MPD offers improved thermal performance (15000 Hrs @ 105°C vs. 2000 Hrs @ 85°C) and is suitable for direct substitution on existing PCBs.

Q: What is the difference between 400LLE2.2MEFC8X11.5 and 400LLE2R2MEFC8X11.5? A: Both parts are from Rubycon's LLE series with identical electrical and mechanical specifications. The primary difference is inventory availability (1492 Pcs vs. 99967 Pcs). Both provide 15000 hours at 105°C operation and are suitable for direct replacement of UVK2G2R2MPD.

Q: Can UVR2G2R2MPD be used as a substitute? A: UVR2G2R2MPD is not a direct substitute due to different lead spacing (0.197" vs. 0.138") and larger case diameter (0.394" vs. 0.315"). This part requires PCB layout modification and is not recommended for direct replacement applications.

Q: Which substitute part has the longest operational life? A: 400LLE2R2MEFC8X11.5 and 400LLE2.2MEFC8X11.5 from Rubycon both provide 15000 hours at 105°C, the highest lifetime rating among all listed substitutes. Both maintain identical physical dimensions to UVK2G2R2MPD.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the original UVK2G2R2MPD specification.

Q: What is the advantage of selecting an Active product status part? A: Active product status parts (400LEX2.2MEFC8X11.5, 400LLE2.2MEFC8X11.5, 400LLE2R2MEFC8X11.5, MAL214252286E3, ESMG401ELL2R2MHB5D, ESMQ401ELL2R2MHB5D) are in current production and offer long-term supply availability. Not For New Designs parts may face supply discontinuation.

Q: Can substitute parts be used in high-temperature applications? A: Yes. 400LEX2.2MEFC8X11.5 operates to 125°C, and 400LLE2.2MEFC8X11.5, 400LLE2R2MEFC8X11.5, and MAL214252286E3 operate to 105°C, compared to UVK2G2R2MPD's 85°C maximum. Selection depends on application temperature requirements.
