Substitute parts are grouped into three categories:

Direct Substitutes maintain all core electrical and mechanical parameters identical to the main part. These include UVR2A010MDD, 100YXJ1M5X11, 105CKE100M, 105KXM100M, 515D105M100JA6AE3, and SK010M100ST.

Upgrade Substitutes offer improved performance characteristics while maintaining full compatibility. These include UKL2A010KDD (tighter ±10% tolerance), EKYA101ELL1R0ME11D (5000 Hrs @ 105°C lifetime), ESH105M100AC3AA (2000 Hrs @ 105°C lifetime), and ESL105M100AC3AA (8000 Hrs @ 105°C lifetime with lower ESR).

All substitute parts comply with RoHS3 and REACH requirements, ensuring regulatory compatibility for modern applications.

Engineering Selection Recommendations

For Direct Replacement (Obsolete Status Mitigation): UVR2A010MDD is the primary direct substitute, offering identical electrical and mechanical specifications with RoHS3 compliance. This part maintains the same Nichicon UVR series characteristics while addressing regulatory requirements.

For Extended Lifetime Applications: EKYA101ELL1R0ME11D (Chemi-Con KYA series) and ESL105M100AC3AA (KEMET ESL series) provide 5000 and 8000 hour lifetimes respectively at 105°C, compared to the original 2000 hours at 85°C. These upgrades are suitable for applications requiring enhanced reliability and extended operational life.

For Improved Tolerance: UKL2A010KDD offers ±10% tolerance versus the original ±20%, providing tighter capacitance control for precision applications while maintaining Nichicon manufacturing heritage.

For Active Product Status: 100YXJ1M5X11, 105CKE100M, 105KXM100M, EKYA101ELL1R0ME11D, ESH105M100AC3AA, ESL105M100AC3AA, and SK010M100ST are all active products with current manufacturing support and established supply chains.

All recommended substitutes are RoHS3 compliant and REACH unaffected, meeting modern regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can UVR2A010MDA be replaced with any 1 µF, 100 V capacitor? A: No. Substitutes must match the exact package type (Radial, Can), lead spacing (0.079" / 2.00 mm), mounting type (Through Hole), and polarization (Polar). Capacitance and voltage ratings must be exact matches.

Q: What is the difference between direct substitutes and upgrade substitutes? A: Direct substitutes maintain all original specifications. Upgrade substitutes improve specific parameters—such as tolerance (UKL2A010KDD at ±10%), lifetime (EKYA101ELL1R0ME11D at 5000 Hrs @ 105°C), or ESR characteristics (ESL105M100AC3AA)—while remaining fully compatible.

Q: Is the UVR2A010MDD a drop-in replacement? A: Yes. UVR2A010MDD is electrically and mechanically identical to UVR2A010MDA, with the addition of RoHS3 compliance. It requires no circuit modifications.

Q: Why do some substitutes have higher operating temperature ranges? A: Upgrade substitutes from manufacturers like Rubycon, Cornell Dubilier, Chemi-Con, and KEMET are rated to 105°C instead of 85°C, extending usable temperature range and lifetime at elevated temperatures.

Q: What does "Obsolete" product status mean for the original part? A: Obsolete status indicates the UVR2A010MDA is no longer manufactured. Active substitute parts ensure continued availability for production and maintenance applications.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts carry RoHS3 compliance certification, meeting current regulatory requirements for electronic components.

Q: Can I use SK010M100ST as a substitute despite its slightly taller height (0.512" vs. 0.492")? A: SK010M100ST is mechanically compatible with identical lead spacing and diameter. The 0.020" height difference must be evaluated against specific PCB layout constraints and clearance requirements in your application.
