Engineering Selection Recommendations

For Direct Replacement (Same Footprint and Performance): UPM2G100MHD and UPW2G100MHD are Nichicon obsolete-series parts that maintain identical lead spacing (0.197" / 5.00mm) and case diameter (0.492" / 12.50mm) as the UPS2G100MHD. Both offer extended lifetime ratings (5000 Hrs and 7000 Hrs respectively) while preserving the original electrical specifications. These parts are suitable for direct PCB substitution without layout modifications.

For Active Production (Manufacturer Recommended): UCS2W100MHD is the Nichicon manufacturer-recommended substitute. This active-status part operates at 450 V (50 V higher than the original specification), providing additional voltage margin. The 10000-hour lifetime at 105°C significantly exceeds the original 3000-hour rating. Physical dimensions differ slightly in height (0.846" vs. 1.063"), requiring verification of available PCB clearance. This part is suitable for new designs and ongoing production.

For Space-Constrained Applications: UCY2G100MPD and UVY2G100MPD offer reduced physical dimensions (0.394" diameter, 0.689" height) while maintaining the 0.197" lead spacing. Both deliver 10000-hour and 2000-hour lifetimes respectively. These parts require PCB layout verification due to smaller case diameter but fit within the same lead spacing footprint.

For Non-Critical Applications: UAQ2G100MHD and UVZ2G100MHD are active-status Nichicon alternatives with 400 V ratings and 2000-hour lifetimes. These parts are suitable for general-purpose applications where extended lifetime is not required.

For Cross-Manufacturer Sourcing: EKMG401ELL100MJ20S (Chemi-Con KMG series) and EKXG401ELL100MJ20S (Chemi-Con KXG series) provide alternative sourcing from an established manufacturer. Both maintain 400 V ratings, 0.197" lead spacing, and ROHS3 compliance. The KXG variant offers 8000-hour lifetime with active product status.

Parts to Avoid for New Designs: URZ2G100MHD, UVY2G100MPD, and UVZ2G100MHD carry either "Not For New Designs" or legacy status designations. These parts are suitable only for maintenance and repair of existing equipment.

Frequently Asked Questions (FAQ)

Q: Can I use UCS2W100MHD as a direct replacement for UPS2G100MHD? A: UCS2W100MHD is electrically compatible (10 µF, 400 V minimum, ±20% tolerance, polar, radial can package). The 450 V rating provides additional voltage margin. However, the height differs (0.846" vs. 1.063"), requiring verification of available PCB clearance above the component. Lead spacing remains identical at 0.197" (5.00mm).

Q: What is the difference between Nichicon UPM2G100MHD and UPW2G100MHD? A: Both are Nichicon obsolete-series parts with identical electrical specifications (10 µF, 400 V, ±20%). The primary difference is lifetime rating: UPM2G100MHD is rated 5000 hours at 105°C, while UPW2G100MHD is rated 7000 hours. UPW2G100MHD also has a slightly shorter height (0.984" vs. 1.063"). Both maintain the same lead spacing and case diameter as the original UPS2G100MHD.

Q: Are Chemi-Con EKMG401ELL100MJ20S and EKXG401ELL100MJ20S compatible with the UPS2G100MHD? A: Both Chemi-Con parts are electrically compatible (10 µF, 400 V, ±20% tolerance, polar, radial can, 0.197" lead spacing, ROHS3 compliant). The EKMG variant has 1000-hour lifetime, while EKXG has 8000-hour lifetime. Both have reduced case diameter (0.394" vs. 0.492"), which may allow easier PCB routing but requires verification of mechanical fit in the original mounting location.

Q: Why does URZ2G100MHD have different lead spacing? A: URZ2G100MHD uses 0.295" (7.50mm) lead spacing compared to the standard 0.197" (5.00mm) of the UPS2G100MHD. This part is not suitable as a direct replacement without PCB modification. It is listed as an alternative only for applications where lead spacing can be accommodated.

Q: What does "Not For New Designs" mean for UVY2G100MPD and UVZ2G100MHD? A: "Not For New Designs" indicates these parts are in legacy status and may have limited future availability. They are suitable for maintenance and repair of existing equipment but should not be specified for new product development. Active-status alternatives such as UCY2G100MPD or UCS2W100MHD are recommended for new designs.

Q: Can I substitute a 450 V rated capacitor in a 400 V circuit? A: Yes. A higher voltage rating provides additional safety margin and does not degrade circuit performance. The UCS2W100MHD (450 V) is suitable for circuits designed for 400 V operation. The capacitor will operate within its rated specifications.

Q: What is the significance of the 10000-hour lifetime rating in UCY2G100MPD and UCS2W100MHD? A: The 10000-hour lifetime at 105°C indicates extended operational life compared to the original UPS2G100MHD (3000 hours). This translates to improved reliability and longer service intervals in applications subject to sustained elevated temperatures. For general-purpose applications at lower operating temperatures, the practical benefit may be less significant.

Q: Are all listed substitute parts ROHS3 compliant? A: Yes. All substitute parts listed carry ROHS3 compliance certification, matching the original UPS2G100MHD specification. This ensures compatibility with environmental and regulatory requirements.
