Frequently Asked Questions (FAQ)

Q: Can UVR1H2R2MDD be used as a direct replacement for UVR1H2R2MDA? A: Yes. UVR1H2R2MDD is a direct equivalent with identical capacitance (2.2 µF), voltage rating (50 V), tolerance (±20%), lifetime (2000 Hrs @ 85°C), and physical dimensions. The primary difference is RoHS3 compliance and higher inventory availability.

Q: What is the difference between UPJ1H2R2MDD and UPM1H2R2MDD? A: Both parts share identical electrical specifications (2.2 µF, 50 V, ±20%, 2000 Hrs @ 105°C, -55°C ~ 105°C). UPM1H2R2MDD carries AEC-Q200 automotive certification and has lower impedance (5 Ohms vs. 6.5 Ohms), making it suitable for automotive applications.

Q: Can I use a 100 V rated capacitor in place of a 50 V rated capacitor? A: Yes. Higher voltage ratings are acceptable substitutes for lower voltage applications, provided all other parameters (capacitance, tolerance, package, lead spacing, physical dimensions) match. UVR2A2R2MDD, UKL2A2R2KDD, UPJ2A2R2MDD, UPM2A2R2MDD, 100YXJ2.2M5X11, and 225CKE100M all provide this upgrade path.

Q: What is the advantage of UPV1H2R2MFD over UPJ1H2R2MDD? A: UPV1H2R2MFD offers extended lifetime (5000 Hrs @ 105°C vs. 2000 Hrs @ 105°C) while maintaining the same voltage rating (50 V), capacitance (2.2 µF), and operating temperature range (-55°C ~ 105°C). This provides improved reliability for long-life applications.

Q: Are cross-manufacturer parts (Rubycon, Cornell Dubilier) compatible with Nichicon parts? A: Yes, provided electrical specifications and physical dimensions match. 100YXJ2.2M5X11 (Rubycon) and 225CKE100M (Cornell Dubilier) maintain identical capacitance (2.2 µF), voltage (100 V), tolerance (±20%), lead spacing (0.079" / 2.00 mm), and package type (Radial, Can). Cross-manufacturer substitution requires verification of application-specific requirements.

Q: Which substitute offers the best long-term supply availability? A: 100YXJ2.2M5X11 (Rubycon) and 225CKE100M (Cornell Dubilier) have Active product status, ensuring ongoing manufacturing and supply chain continuity. All Nichicon substitutes listed are classified as Obsolete.

Q: Can I use UKL2A2R2KDD as a substitute if I need tighter tolerance? A: Yes. UKL2A2R2KDD provides ±10% tolerance compared to ±20% for the original part, with identical 2.2 µF capacitance and 100 V rating. However, this is a voltage upgrade (100 V vs. 50 V) and should be verified for application compatibility.

Q: What is the impact of operating temperature range differences? A: The original UVR1H2R2MDA operates from -40°C ~ 85°C. Substitutes with extended range (-55°C ~ 105°C) such as UPJ, UPM, and UPV series provide wider environmental tolerance. For applications within the original temperature range, both original and extended-range parts are functionally equivalent.
