Frequently Asked Questions (FAQ)
Q: Can I use UVK1J101MPD as a substitute for UVR1H101MPD? A: No. UVK1J101MPD has a 63 V voltage rating, while UVR1H101MPD is rated 50 V. Although higher voltage ratings provide design margin, this part does not meet the critical parameter match requirement for direct substitution.
Q: What is the difference between UVR1H101MPD and UVR1H101MPD1FA? A: Both parts are electrically and mechanically identical with matching 100 µF capacitance, 50 V rating, and physical dimensions. The primary difference is product status: UVR1H101MPD is "Not For New Designs" while UVR1H101MPD1FA is "Active," indicating current manufacturing and supply availability.
Q: Are Cornell Dubilier parts 107CKH050M and 107KXM050M interchangeable with Nichicon UVR1H101MPD? A: Yes. Both Cornell Dubilier parts meet all critical parameters: 100 µF capacitance, 50 V rating, ±20% tolerance, identical lead spacing (0.138"), case diameter (0.315"), and height (0.512"). Both are Active status products with established supply chains. 107KXM050M offers extended lifetime (3000 Hrs @ 105°C) compared to the original specification.
Q: What packaging options are available? A: UVR1H101MPD1TA is available in Tape & Box (TB) packaging for automated assembly. All other listed substitutes are available in Bulk packaging. Both packaging formats are acceptable for through-hole mounting applications.
Q: Does UHD1H101MPD provide better performance than the original UVR1H101MPD? A: UHD1H101MPD extends the operating temperature range to 105°C and provides 3000 hours lifetime at 105°C versus 2000 hours at 85°C for the original. It also offers higher ripple current capability (506.8 mA @ 120 Hz versus 260 mA). These enhancements provide improved reliability margins while maintaining identical physical dimensions and lead spacing.
Q: Is the Rubycon 50YXF100MEFC8X11.5 a suitable replacement? A: Yes. The Rubycon part meets all critical electrical and mechanical specifications with 100 µF capacitance, 50 V rating, and identical physical dimensions. It offers the highest lifetime rating (7000 Hrs @ 105°C) among available options. Note that this part is classified "Last Time Buy," indicating limited future availability.
Q: Can I substitute parts with different manufacturers? A: Yes. All listed substitutes from Cornell Dubilier and Rubycon meet the critical parameter requirements for the Nichicon UVR1H101MPD. Cross-manufacturer substitution is valid when electrical specifications, mechanical dimensions, and lead spacing match exactly.
Q: What should I verify before implementing a substitute part? A: Verify that the substitute part matches these critical parameters: 100 µF capacitance, 50 V voltage rating, ±20% tolerance, 0.138" lead spacing, 0.315" case diameter, 0.512" height, and through-hole mounting configuration. Confirm RoHS compliance status matches your application requirements.
