Tolerance: ±20% (standard tolerance match)
Mounting Type: Through Hole (mechanical compatibility)
Package Type: Radial, Can (form factor requirement)
Lead Spacing: 0.098" (2.50mm) preferred for direct PCB compatibility
Case Diameter: 0.248" (6.30mm) preferred for space constraints
Operating Temperature: -40°C ~ 105°C minimum (full range match)
RoHS Compliance: ROHS3 Compliant (regulatory requirement)

Parts are grouped into three categories:

Direct Equivalent: UVZ2D010MED (Nichicon) — identical electrical specifications with minor lifetime variance (1000 Hrs vs. 2000 Hrs @ 105°C).

Upgrade Substitute: 517D105M250AA6AE3 (Vishay Sprague) — higher voltage rating (250 V) with equivalent lifetime (2000 Hrs @ 105°C), suitable for applications requiring voltage margin.

Compatible Alternatives: MAL214232108E3, MAL214252108E3, MAL214272108E3 (Vishay Beyschlag/Draloric/BC Components) and SEK010M200ST (Cornell Dubilier Electronics) — all meet electrical specifications with extended lifetime (2500 Hrs or 2000 Hrs @ 105°C) but feature dimensional variations in lead spacing and case diameter.

Engineering Selection Recommendations

For Direct Replacement (Minimal Design Change)

UVZ2D010MED offers the closest electrical and mechanical match to UPW2D010MED. Both are Nichicon products with identical capacitance, voltage, tolerance, and form factor. The primary difference is reduced lifetime (1000 Hrs vs. 2000 Hrs @ 105°C). This substitute is suitable for applications where the original 2000-hour specification is not critical. Both parts are obsolete; inventory availability should be confirmed before selection.

For Voltage Margin Enhancement

517D105M250AA6AE3 (Vishay Sprague) provides a 250 V rating while maintaining 2000-hour lifetime and identical mechanical dimensions. This upgrade is appropriate for designs requiring additional voltage safety margin or operating in environments with voltage transients. The part is obsolete but maintains full electrical compatibility.

For Active Production Support

MAL214252108E3 and MAL214272108E3 (Vishay Beyschlag/Draloric/BC Components) and SEK010M200ST (Cornell Dubilier Electronics) are active products with extended lifetime ratings (2500 Hrs or 2000 Hrs @ 105°C). These alternatives provide long-term supply continuity and regulatory compliance. MAL214252108E3 and SEK010M200ST maintain the original 0.098" (2.50mm) lead spacing and 0.248" (6.30mm) case diameter, enabling direct PCB compatibility. MAL214232108E3 and MAL214272108E3 feature larger case diameters (0.197" / 5.00mm) and require PCB layout verification before implementation.

All substitute parts maintain ROHS3 compliance and operate across the full -40°C to 105°C temperature range.

Frequently Asked Questions (FAQ)

Q: Can UVZ2D010MED be used as a direct replacement for UPW2D010MED?

A: Yes, UVZ2D010MED is electrically and mechanically compatible. Both share identical capacitance (1 µF), voltage rating (200 V), tolerance (±20%), lead spacing (0.098" / 2.50mm), case diameter (0.248" / 6.30mm), and operating temperature range (-40°C ~ 105°C). The primary difference is lifetime: UVZ2D010MED is rated for 1000 hours at 105°C compared to 2000 hours for UPW2D010MED. Substitution is valid if the application does not require the extended 2000-hour specification.

Q: What is the advantage of using 517D105M250AA6AE3?

A: 517D105M250AA6AE3 provides a higher voltage rating (250 V vs. 200 V) while maintaining the same 2000-hour lifetime and identical mechanical form factor. This upgrade is beneficial for applications operating near the voltage limit or subject to voltage transients, as it provides additional safety margin without requiring PCB redesign.

Q: Why do MAL214232108E3 and MAL214272108E3 have different lead spacing?

A: MAL214232108E3 features 0.197" (5.00mm) lead spacing, while MAL214272108E3 maintains 0.098" (2.50mm) lead spacing matching the original UPW2D010MED. Both have larger case diameters (0.197" / 5.00mm vs. 0.248" / 6.30mm). Lead spacing and case diameter determine PCB hole positioning and component footprint. MAL214272108E3 is preferred if PCB layout cannot be modified.

Q: Are active product substitutes available?

A: Yes. MAL214252108E3, MAL214272108E3 (Vishay Beyschlag/Draloric/BC Components), and SEK010M200ST (Cornell Dubilier Electronics) are active products. MAL214252108E3 and SEK010M200ST maintain the original 0.098" (2.50mm) lead spacing and 0.248" (6.30mm) case diameter, enabling direct PCB compatibility. All three offer extended lifetime (2500 Hrs or 2000 Hrs @ 105°C) and ensure long-term supply availability.

Q: What is the impact of case diameter differences?

A: Case diameter affects component footprint and available board space. UPW2D010MED, UVZ2D010MED, 517D105M250AA6AE3, and SEK010M200ST all use 0.248" (6.30mm) diameter. MAL214232108E3, MAL214252108E3, and MAL214272108E3 use 0.197" (5.00mm) diameter, requiring verification that the smaller diameter is compatible with the PCB layout and mechanical clearances.

Q: Do all substitutes meet RoHS compliance?

A: Yes. All listed substitutes are ROHS3 compliant, meeting regulatory requirements for hazardous substance restrictions.

Q: What is the difference between ripple current specifications?

A: Ripple current capacity varies slightly among substitutes. UPW2D010MED specifies 27.2 mA @ 10 kHz. UVZ2D010MED specifies 25.6 mA @ 10 kHz. 517D105M250AA6AE3 specifies 27.2 mA @ 10 kHz. Vishay and Cornell Dubilier parts specify 27 mA @ 10 kHz. These variations are within acceptable tolerance for general-purpose applications but should be confirmed if the design operates at maximum ripple current limits.
