UVR2A2R2MDA Equivalent & Substitute Parts

Part Overview

The UVR2A2R2MDA is a 2.2 µF, 100 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is rated for 2000 hours at 85°C and is classified as obsolete. Due to its obsolete status, equivalent and substitute parts from active manufacturers or upgraded series are necessary for new designs and ongoing production requirements.

Substitute Part Grouping Explanation

Substitution for the UVR2A2R2MDA is determined by the following mandatory parameters:

Capacitance: 2.2 µF (exact match required)
Voltage Rating: 100 V (exact match required)
Tolerance: ±20% (acceptable; ±10% represents improved tolerance)
Package: Radial, Can with 0.079" (2.00 mm) lead spacing
Mounting: Through Hole
Polarization: Polar

Substitute parts are grouped into three categories:

Direct Substitutes (Packaging Variant): Parts with identical electrical specifications and physical dimensions but different packaging or RoHS compliance status.

Upgrade Substitutes: Parts with improved specifications such as higher temperature ratings (105°C vs. 85°C), tighter tolerance (±10% vs. ±20%), or extended lifetime ratings, while maintaining the same capacitance, voltage, and package footprint.

Similar Substitutes: Parts from alternative manufacturers meeting the same core electrical and mechanical requirements with minor variations in ripple current or impedance characteristics.

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): UVR2A2R2MDD is the direct substitute from Nichicon, offering identical electrical and mechanical specifications with ROHS3 compliance. Both parts are obsolete; however, UVR2A2R2MDD has higher inventory availability (3738 pcs vs. 979 pcs).

For Improved Tolerance: UKL2A2R2KDD provides ±10% tolerance versus the original ±20%, maintaining the same 2000-hour lifetime at 85°C. This part is suitable for applications requiring tighter capacitance tolerance while preserving thermal characteristics.

For Extended Temperature Range and Lifetime: UPJ2A2R2MDD and UPM2A2R2MDD both extend the operating temperature range to -55°C ~ 105°C with 2000-hour lifetime at 105°C. UPM2A2R2MDD carries AEC-Q200 automotive qualification, making it suitable for automotive applications. Both are ROHS3 compliant.

For Active Product Status with Extended Lifetime: 100YXJ2.2M5X11 (Rubycon) and EKYA101ELL2R2ME11D (Chemi-Con) are active products with 5000-hour lifetime ratings at 105°C, providing superior reliability for long-term applications. Both are ROHS3 compliant and maintain identical package footprints.

For Alternative Manufacturers: 225CKE100M and 225KXM100M (Cornell Dubilier / Illinois Capacitor) and ECA-2AM2R2 (Panasonic) are active alternatives meeting the same electrical specifications. SK2R2M100ST (CDE) is also active but features a slightly taller package (0.512" vs. 0.492"), requiring PCB layout verification.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with ±10% tolerance instead of ±20%? A: Yes. UKL2A2R2KDD offers ±10% tolerance, which is tighter than the original ±20%. Tighter tolerance does not create compatibility issues; it provides improved capacitance accuracy.

Q: What is the difference between parts rated at 85°C and 105°C? A: The temperature rating indicates the maximum operating temperature at which the part maintains its specified lifetime. Parts rated at 105°C (UPJ2A2R2MDD, UPM2A2R2MDD, 100YXJ2.2M5X11, EKYA101ELL2R2ME11D, 225CKE100M, 225KXM100M) are suitable for higher-temperature environments. The original UVR2A2R2MDA is rated at 85°C.

Q: Does RoHS compliance affect electrical performance? A: No. ROHS3 compliance indicates the absence of restricted substances (lead, cadmium, mercury, etc.) but does not alter electrical characteristics. The original UVR2A2R2MDA is RoHS non-compliant; all substitutes listed are ROHS3 compliant.

Q: Are there height differences I need to consider for PCB layout? A: Yes. Most substitutes maintain the 0.492" (12.50 mm) height of the original part. However, UKL2A2R2KDD, UPJ2A2R2MDD, and ECA-2AM2R2 are 0.472" (12.00 mm) tall, and SK2R2M100ST is 0.512" (13.00 mm) tall. Verify PCB clearance before selection.

Q: What does "active" product status mean? A: Active products are currently manufactured and available from the supplier. Obsolete products are no longer in production. For new designs, active products (100YXJ2.2M5X11, 225CKE100M, 225KXM100M, EKYA101ELL2R2ME11D, ECA-2AM2R2, SK2R2M100ST) are recommended for long-term supply chain stability.

Q: Can I use a part with higher ripple current rating? A: Yes. Higher ripple current ratings indicate the part can handle greater AC current without exceeding temperature limits. This is a beneficial characteristic and does not create compatibility issues.

Q: Is AEC-Q200 qualification important for my application? A: AEC-Q200 qualification is required only for automotive applications. UPM2A2R2MDD carries this certification. For non-automotive applications, this qualification is not necessary.
