Engineering Selection Recommendations

Direct Nichicon Equivalents: UVR2A101MPD1AA is the active-status equivalent within the Nichicon UVR series, maintaining identical electrical and mechanical specifications while offering current availability. UVK2A101MPD provides a Nichicon alternative with reduced height (0.630" vs 0.866"), suitable for space-constrained applications where vertical clearance is limited.

Cross-Manufacturer Substitutes with Equivalent Performance: ECA-2AM101 and ECA-2AM101B (Panasonic) and ESMG101ELL101MJ20S (Chemi-Con) are electrically equivalent with 2000-hour lifetime ratings at 85°C. These parts maintain identical capacitance, voltage, tolerance, and lead spacing. Height variations (0.669" to 0.846") remain within acceptable mechanical compatibility limits for standard through-hole PCB layouts.

Upgraded Performance Alternatives: 100ZLJ100M10X20, 100YXJ100M10X20, and 100ZLH100MEFC10X20 (Rubycon) offer extended lifetime ratings of 10000 hours at 105°C with expanded operating temperature ranges (-40°C to 105°C). These upgrades provide superior reliability for applications requiring enhanced thermal performance and extended service life. ECA-2AHG101 (Panasonic) extends the operating temperature range to -55°C ~ 105°C with 2000-hour lifetime at 105°C, suitable for extreme temperature environments.

All substitute parts listed are ROHS3 compliant and maintain the same polarization, mounting type, and lead spacing as the original UVR2A101MPD.

Frequently Asked Questions (FAQ)

Q: Can UVK2A101MPD replace UVR2A101MPD in all applications? A: UVK2A101MPD is electrically equivalent but has a reduced height of 0.630" compared to 0.866". It is suitable for replacement in applications where vertical space is available. Verify PCB layout clearance before substitution.

Q: What is the difference between the 2000-hour and 10000-hour lifetime ratings? A: The 2000-hour rating applies at 85°C operating temperature, while the 10000-hour rating applies at 105°C. The 10000-hour parts (Rubycon ZLJ and ZLH series) provide extended service life and are suitable for high-reliability applications or environments with elevated ambient temperatures.

Q: Are Rubycon and Panasonic parts direct replacements for Nichicon UVR2A101MPD? A: Yes, when electrical parameters match exactly: 100 µF capacitance, 100 V voltage rating, ±20% tolerance, and 0.197" lead spacing. Mechanical dimensions (case diameter and height) may vary slightly but remain compatible with standard through-hole PCB designs. Verify physical fit in your specific application.

Q: Why does URS2A101MHD have a larger case diameter (0.492" vs 0.394")? A: URS2A101MHD is a similar-performance part from Nichicon with a larger diameter (12.50 mm) but shorter height (0.650"). This geometry may not fit in PCB layouts designed for the original 10.00 mm diameter. Use only if PCB footprint accommodates the larger diameter.

Q: Which substitute offers the best performance upgrade? A: 100ZLJ100M10X20 (Rubycon) and 100ZLH100MEFC10X20 (Rubycon) provide the highest performance with 10000-hour lifetime at 105°C and operating temperature range to 105°C. ECA-2AHG101 (Panasonic) extends the lower temperature limit to -55°C for extreme cold environments.

Q: Are all listed parts ROHS3 compliant? A: All substitute parts listed are ROHS3 compliant, matching the compliance status of the original UVR2A101MPD.

Q: What packaging options are available? A: Most parts are available in Bulk packaging. ECA-2AM101B is available in Cut Tape (CT) packaging for automated assembly processes. Verify packaging availability with your supplier for your specific procurement requirements.
