Tolerance: Must be ±20%
Polarization: Must be Polar
Mounting Type: Must be Through Hole
Package Type: Must be Radial, Can
Operating Temperature Range: Must support -40°C ~ 105°C minimum

Substitute parts are grouped into three categories based on mechanical compatibility and performance characteristics:

Category 1 - Same Footprint (Lead Spacing 0.197" / 5.00mm): UCS2D101MND9, UCY2D101MHD, UAS2D101MHD6 (partial match). These parts maintain identical lead spacing and are direct mechanical replacements with varying lifetime ratings and ripple current capabilities.

Category 2 - Alternate Footprint (Lead Spacing 0.295" / 7.50mm): UAS2D101MHD6, UCY2D101MHD3, UPJ2D101MHD, UPW2D101MHD, URZ2D101MHD, UVY2D101MHD, UVZ2D101MHD, EKXG201ELL101ML20S. These parts require PCB layout modification due to different lead spacing and physical dimensions but maintain electrical equivalence.

Category 3 - Cross-Manufacturer (Chemi-Con): EKXG201ELL101ML20S. Non-Nichicon equivalent with identical electrical specifications and enhanced lifetime rating.

Engineering Selection Recommendations

For Direct Mechanical Replacement (Same Footprint - 5.00mm Lead Spacing)

UCS2D101MND9 is the primary substitute when identical PCB layout is required. This part maintains the 0.197" (5.00mm) lead spacing of the UAS2D101MHD while providing extended lifetime (10000 hours at 105°C versus 2000 hours) and superior ripple current handling. Both parts are Active status and ROHS3 compliant. The UCS2D101MND9 is suitable for applications requiring enhanced reliability without layout modification.

UCY2D101MHD provides 12000-hour lifetime at 105°C with the same lead spacing and maintains Active product status. This part offers the highest ripple current capability (695 mA @ 120 Hz, 1.39 A @ 100 kHz) among same-footprint options. REACH Status is Affected for this part.

For Alternate Footprint Applications (7.50mm Lead Spacing)

UAS2D101MHD6 maintains identical electrical specifications and lifetime rating (2000 hours at 105°C) as the primary part but requires 7.50mm lead spacing accommodation. This part is Active status and ROHS3 compliant, suitable for designs where physical space constraints necessitate a larger diameter can (16.00mm) with reduced height (22.00mm).

UCY2D101MHD3 offers 12000-hour lifetime with 7.50mm lead spacing and Active product status. This part provides the highest ripple current among alternate-footprint options (710 mA @ 120 Hz, 1.42 A @ 100 kHz). REACH Status is Affected.

EKXG201ELL101ML20S (Chemi-Con KXG series) provides 10000-hour lifetime with 7.50mm lead spacing and represents a cross-manufacturer equivalent. This part is Active status, ROHS3 compliant, and REACH Unaffected. It offers the most compact height (20.00mm) among 7.50mm lead spacing options.

For Obsolete or Legacy Applications

UPJ2D101MHD and UPW2D101MHD are classified as Obsolete and should not be selected for new designs. These parts are listed for reference only when servicing existing equipment.

UVY2D101MHD and UVZ2D101MHD are classified as Not For New Designs and should not be selected for new product development.

URZ2D101MHD is Active status but provides only 1000-hour lifetime at 105°C, making it unsuitable for applications requiring extended operational life.

Frequently Asked Questions (FAQ)

Q: Can UCS2D101MND9 be used as a direct replacement for UAS2D101MHD without PCB modification?

A: Yes. Both parts share identical lead spacing (0.197" / 5.00mm) and through-hole radial can package. The UCS2D101MND9 can be installed in the same PCB footprint. The primary difference is extended lifetime (10000 hours versus 2000 hours at 105°C) and improved ripple current handling, making it a superior substitute without layout changes.

Q: What is the difference between 5.00mm and 7.50mm lead spacing?

A: Lead spacing refers to the distance between the two radial leads on the capacitor. A 5.00mm spacing requires PCB holes drilled 5.00mm apart, while 7.50mm spacing requires holes 7.50mm apart. These are not interchangeable without PCB redesign. Verify your PCB layout before selecting a substitute with different lead spacing.

Q: Why do some substitutes have longer lifetimes?

A: Lifetime rating (measured in hours at 105°C) indicates the expected operational duration before capacitance degradation reaches specified limits. Different Nichicon series (UAS, UCS, UCY, UPJ, UPW, URZ, UVY, UVZ) employ different internal designs and materials. Higher lifetime ratings reflect enhanced internal construction and are suitable for applications requiring extended reliability.

Q: Is EKXG201ELL101ML20S from Chemi-Con electrically equivalent to the Nichicon UAS2D101MHD?

A: Yes. The EKXG201ELL101ML20S matches all core electrical parameters: 100 µF capacitance, 200 V rating, ±20% tolerance, polar configuration, and -40°C to 105°C operating range. It requires 7.50mm lead spacing accommodation. The Chemi-Con part offers 10000-hour lifetime and is REACH Unaffected, making it suitable for applications with extended reliability requirements and REACH compliance needs.

Q: Can I use URZ2D101MHD as a substitute?

A: URZ2D101MHD is electrically equivalent but provides only 1000-hour lifetime at 105°C compared to UAS2D101MHD's 2000 hours. This part is suitable only for applications with minimal thermal stress or short operational duration. For standard applications, higher-lifetime alternatives (UCS2D101MND9, UCY2D101MHD, UCY2D101MHD3) are recommended.

Q: Should I use parts marked as "Not For New Designs"?

A: UVY2D101MHD and UVZ2D101MHD are marked "Not For New Designs" and should be avoided for new product development. These parts are listed for reference when servicing or repairing existing equipment only. For new designs, select from Active status parts: UCS2D101MND9, UCY2D101MHD, UCY2D101MHD3, or EKXG201ELL101ML20S.

Q: What does ROHS3 Compliant mean?

A: ROHS3 (Restriction of Hazardous Substances Directive 3) compliance indicates the component meets European Union restrictions on hazardous materials including lead, mercury, cadmium, and certain flame retardants. All listed substitutes are ROHS3 compliant, ensuring regulatory compliance for EU market applications.

Q: How do I determine which substitute is best for my application?

A: Evaluate three factors: (1) PCB layout constraints—if lead spacing cannot be modified, select 5.00mm spacing parts (UCS2D101MND9, UCY2D101MHD); (2) Reliability requirements—if extended lifetime is needed, select 10000+ hour parts (UCS2D101MND9, UCY2D101MHD, UCY2D101MHD3, EKXG201ELL101ML20S); (3) Ripple current demands—if high-frequency ripple current handling is required, select parts with higher ripple current ratings (UCY series, UCS2D101MND9, EKXG201ELL101ML20S).
