UVR2D100MPA Equivalent & Substitute Parts

Part Overview

The UVR2D100MPA is a 10 µF, 200 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete, making substitute parts necessary for ongoing maintenance, repair, and legacy system support. The part operates across a temperature range of -40°C to 85°C with a rated lifetime of 2000 hours at 85°C, serving general-purpose applications requiring stable capacitance and ripple current handling.

Substitute Part Grouping Explanation

Substitute parts for the UVR2D100MPA are qualified based on the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

Capacitance: 10 µF (exact match required)
Voltage Rating: 200 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Lifetime: 2000 Hrs @ 85°C (exact match required)

Mechanical Compatibility Criteria:

Package Type: Radial, Can (exact match required)
Mounting Type: Through Hole (exact match required)
Lead Spacing: 0.197" (5.00mm) (exact match required)
Diameter: 0.394" (10.00mm) (exact match required)
Height: Physical dimensions must accommodate PCB layout constraints

Substitutes are classified as either direct manufacturer equivalents (same manufacturer, different product status) or similar cross-manufacturer alternatives (different manufacturer, identical electrical and mechanical specifications).

Engineering Selection Recommendations

UVR2D100MPD (Direct Nichicon Substitute): This part is the direct manufacturer equivalent from Nichicon, maintaining identical electrical specifications and mechanical dimensions as the UVR2D100MPA. The UVR2D100MPD carries ROHS3 compliance, addressing regulatory requirements where the original part does not. Product status is listed as "Not For New Designs," indicating it remains available for legacy system support and maintenance applications. This substitute is preferred for direct replacement in existing assemblies where Nichicon component continuity is required.

SK100M200ST (Cross-Manufacturer Alternative): The SK100M200ST from Cornell Dubilier Electronics meets all core electrical parameters (10 µF, 200 V, ±20%, 2000 Hrs @ 85°C) and maintains identical lead spacing and diameter. This part carries Active product status and ROHS3 compliance. The physical height is 0.591" (15.00mm) compared to 0.492" (12.50mm) for the main part, requiring verification of PCB layout clearance. The operating temperature minimum is -25°C versus -40°C for the original part. Ripple current specifications are lower (70 mA @ 120 Hz versus 95 mA), which may impact performance in high-ripple applications. This substitute is suitable for applications where cross-manufacturer sourcing is acceptable and physical height constraints permit the additional 0.099" (2.50mm).

Frequently Asked Questions (FAQ)

Q: Can UVR2D100MPD be used as a direct replacement for UVR2D100MPA?

A: Yes. The UVR2D100MPD is electrically and mechanically identical to the UVR2D100MPA, with matching capacitance (10 µF), voltage rating (200 V), tolerance (±20%), lifetime (2000 Hrs @ 85°C), and physical dimensions. The primary difference is improved RoHS3 compliance and different product status classification.

Q: What are the limitations of using SK100M200ST as a substitute?

A: The SK100M200ST introduces two design considerations: (1) Physical height is 0.591" (15.00mm) versus 0.492" (12.50mm), requiring PCB layout verification for clearance; (2) Operating temperature minimum is -25°C instead of -40°C, which may not be suitable for applications requiring full -40°C operation; (3) Ripple current ratings are lower (70 mA @ 120 Hz and 98 mA @ 1 kHz), which may be insufficient for high-ripple current applications.

Q: Are all substitutes through-hole mounted?

A: Yes. All listed substitutes maintain through-hole mounting with 0.197" (5.00mm) lead spacing, ensuring PCB footprint compatibility with the original UVR2D100MPA design.

Q: What is the difference between "Obsolete" and "Not For New Designs" product status?

A: Obsolete status indicates the part is no longer manufactured or available from the original manufacturer. "Not For New Designs" indicates the manufacturer continues limited production for legacy support but does not recommend the part for new circuit designs. Both statuses necessitate substitute part identification for ongoing system maintenance.

Q: Do all substitutes meet RoHS compliance?

A: The original UVR2D100MPA is RoHS non-compliant. Both substitute parts (UVR2D100MPD and SK100M200ST) are ROHS3 compliant, addressing regulatory requirements for applications subject to RoHS directives.
