Substitute Part Grouping Explanation
Substitution for the UVR2F101MHD is determined by the following criteria:
Primary Compatibility Requirements:
- Capacitance: 100 µF (exact match required)
- Tolerance: ±20% (acceptable range)
- Voltage Rating: Equal to or greater than 315 V
- Lead Spacing: 0.295" (7.50mm) (exact match required for PCB compatibility)
- Case Diameter: 0.709" (18.00mm) (exact match required for mechanical fit)
- Mounting Type: Through Hole Radial (exact match required)
- Polarization: Polar (exact match required)
Secondary Considerations:
- Operating temperature range must encompass the application's thermal requirements
- Lifetime rating and ripple current specifications should meet or exceed application demands
- RoHS3 compliance and REACH status must align with regulatory requirements
Substitute parts are grouped into two categories: direct upgrades (higher voltage or improved thermal performance) and equivalent alternatives (same or similar electrical characteristics with different manufacturers).

Engineering Selection Recommendations
Nichicon UAS2G101MHD is the primary recommended upgrade path. It maintains Nichicon series continuity, carries Active product status, and provides 400 V rating with extended operating temperature range to 105°C. This part is suitable for new designs and offers improved thermal performance over the original UVR2F101MHD.
Rubycon 450BXW100MEFR18X35 offers the highest voltage margin (450 V) and exceptional lifetime rating (12000 Hrs @ 105°C), making it suitable for demanding applications requiring extended service life. Note the height is 1.457" versus the original 1.476", which may require PCB layout verification.
Vishay MAL215256101E3 provides automotive-grade qualification (AEC-Q200) with 400 V rating and 4000-hour lifetime at 105°C, suitable for automotive and industrial applications requiring higher reliability standards.
Chemi-Con EKMQ401ELL101MMP1S and ESMQ401ELL101MMP1S are Active alternatives with 400 V rating. The EKMQ variant supports 105°C operation, while ESMQ is rated to 85°C. Both feature reduced height (1.457") compared to the original part.
Rubycon 350PX100KEFC18X35.5 provides tighter tolerance (±10% versus ±20%) at 350 V rating with Active status, suitable for applications where capacitance precision is critical.
All substitute parts maintain RoHS3 compliance and REACH Unaffected status, ensuring regulatory alignment with the original component.
Frequently Asked Questions (FAQ)
Q: Can I use a substitute part with higher voltage rating than the original UVR2F101MHD?
A: Yes. A higher voltage rating is a direct upgrade. The 315 V original part can be replaced with 350 V, 400 V, or 450 V rated alternatives without circuit modification, provided all other parameters (capacitance, tolerance, lead spacing, case diameter, mounting type) remain compatible.
Q: What is the significance of the "Not For New Designs" status?
A: This designation indicates the part has been superseded by newer alternatives in the manufacturer's product line. While existing inventory remains available, the manufacturer recommends using Active-status parts for new circuit designs. For legacy system support, the original part remains functional and available.
Q: Are there mechanical compatibility concerns when substituting parts with different heights?
A: Yes. The original UVR2F101MHD has a maximum seated height of 1.476". Some substitutes (Rubycon BXW series, Chemi-Con KMQ and SMQ series, Vishay 142 RHS series) have heights of 1.457". This 0.019" difference is typically accommodated in standard PCB layouts, but clearance verification is required for applications with tight vertical constraints or specific mechanical requirements.
Q: Which substitute offers the best thermal performance?
A: The Rubycon 450BXW100MEFR18X35 provides the highest thermal rating with 12000 hours lifetime at 105°C, compared to the original 2000 hours at 85°C. This represents a significant improvement for applications operating at elevated temperatures or requiring extended service intervals.
Q: Can I substitute the UVR2F101MHD with a part having ±10% tolerance instead of ±20%?
A: Yes. The Rubycon 350PX100KEFC18X35.5 offers ±10% tolerance, which is tighter than the original ±20%. This provides improved capacitance accuracy and is a direct upgrade for applications where capacitance precision is required.
Q: What is the ripple current significance when selecting a substitute?
A: Ripple current rating determines the maximum AC current the capacitor can safely handle without exceeding temperature limits. The original UVR2F101MHD is rated for 560 mA @ 120 Hz and 896 mA @ 10 kHz. Substitutes with equal or higher ripple current ratings are suitable for the same application. The Rubycon 450BXW100MEFR18X35 provides significantly higher ripple current (835 mA @ 120 Hz, 1.879 A @ 100 kHz), making it suitable for high-ripple applications.
Q: Are all substitute parts RoHS3 compliant?
A: Yes. All listed substitute parts carry RoHS3 Compliant status and REACH Unaffected designation, matching the regulatory compliance of the original UVR2F101MHD.
Q: Which substitute is best for automotive applications?
A: The Vishay MAL215256101E3 carries AEC-Q200 automotive qualification and is specifically rated for automotive applications. It provides 400 V rating, 4000-hour lifetime at 105°C, and meets automotive reliability standards.
