UPS2D3R3MPD Equivalent & Substitute Parts

Part Overview

The UPS2D3R3MPD is a 3.3 µF, 200 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete and is no longer recommended for new designs. The UPS series represents an earlier generation of general-purpose aluminum electrolytic capacitors with a rated lifetime of 2000 hours at 105°C.

Due to its obsolete status, identifying equivalent and substitute parts is essential for ongoing maintenance, repair, and legacy system support. Substitutes are selected based on matching or exceeding the electrical and mechanical specifications while maintaining through-hole radial mounting compatibility.

Tolerance: ±20% (exact match required)
Voltage Rating: 200 V minimum (higher voltage ratings are acceptable as they provide design margin)
Operating Temperature Range: -40°C to 105°C minimum (extended ranges are acceptable)
Polarization: Polar (exact match required)

Mechanical Parameters (Must Match or Be Compatible):

Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)
Lead Spacing: 0.138" (4.60 mm) (exact match required for PCB compatibility)
Case Diameter: 0.315" (8.00 mm) (exact match or smaller acceptable)
Height: Physical height must not exceed available board space

Compliance & Status:

RoHS3 Compliance required
Product status (Active, Obsolete, or Not For New Designs) noted for procurement planning

Substitutes are grouped into three categories: Direct equivalents (same voltage rating), manufacturer-recommended alternatives (higher voltage ratings), and upgraded options (extended lifetime or higher voltage ratings from alternative manufacturers).

Engineering Selection Recommendations

Direct Equivalent (Same Voltage Rating): UPS2D3R3MPD1TD is the direct equivalent with identical electrical specifications and mechanical dimensions. This part maintains the 200 V rating and 2000-hour lifetime. Selection is appropriate when exact specification matching is required and the higher inventory level (1045 pcs) supports availability.

Same Voltage, Enhanced Lifetime: UPW2D3R3MPD provides the same 200 V rating with improved lifetime (3000 hours vs. 2000 hours at 105°C). The reduced height (0.453" vs. 0.512") may provide space advantages in compact layouts. Both parts are obsolete but suitable for legacy system maintenance.

Higher Voltage Rating (Manufacturer-Recommended): UVY2V3R3MPD operates at 350 V, providing increased voltage margin over the original 200 V specification. This part is suitable for applications where voltage transient protection is beneficial. The reduced ripple current rating (30 mA vs. 36 mA at 120 Hz) should be verified against circuit requirements.

Upgraded Performance (Higher Voltage & Extended Lifetime): ULD2G3R3MPD (Nichicon) and 400LLE3R3MEFC8X11.5 (Rubycon) both provide 400 V rating with significantly extended lifetime (15000 hours at 105°C). These parts offer the highest reliability margin and are recommended for critical applications. The ULD2G3R3MPD has slightly increased height (0.531" vs. 0.512"), requiring PCB space verification.

Active Product Status (Recommended for New Designs): 400LLE3R3MEFC8X11.5 (Rubycon, Active status) is the preferred long-term substitute. It provides 400 V rating, 15000-hour lifetime at 105°C, and maintains identical lead spacing and case diameter. Exceptional inventory availability (223,420 pcs) ensures supply continuity. All parts are ROHS3 compliant and REACH unaffected.

Alternative Manufacturer (Active Status): EKXE401ELL3R3MHB5D (Chemi-Con, Active status) provides 400 V rating with 10000-hour lifetime at 105°C. Higher ripple current capability (50 mA @ 120 Hz, 125 mA @ 100 kHz) supports applications with elevated AC stress. Slightly increased height (0.531") requires board space confirmation.

Frequently Asked Questions (FAQ)

Q: Can UPS2D3R3MPD be directly replaced with a higher voltage rating part? A: Yes. Higher voltage-rated capacitors (350 V or 400 V) are direct substitutes for 200 V applications. The higher voltage rating provides design margin and does not affect circuit operation. Mechanical compatibility (lead spacing, case diameter, mounting type) must remain unchanged.

Q: What is the difference between UPS2D3R3MPD and UPS2D3R3MPD1TD? A: Both parts are electrically and mechanically identical with 3.3 µF, 200 V, ±20% tolerance, and 2000-hour lifetime at 105°C. The primary difference is packaging: UPS2D3R3MPD is supplied in standard packaging, while UPS2D3R3MPD1TD is supplied in cut tape (CT). Both are suitable for direct substitution.

Q: Why is UVZ2D3R3MED not recommended as a direct substitute? A: While UVZ2D3R3MED matches the 3.3 µF, 200 V, ±20% specification, it has different mechanical dimensions. The lead spacing is 0.098" (2.50 mm) instead of 0.138" (4.60 mm), and the case diameter is 0.248" (6.30 mm) instead of 0.315" (8.00 mm). These differences prevent direct PCB mounting without layout modification.

Q: What is the advantage of selecting 400LLE3R3MEFC8X11.5 over ULD2G3R3MPD? A: 400LLE3R3MEFC8X11.5 (Rubycon) has Active product status, ensuring long-term availability and supply continuity. It provides identical electrical performance (3.3 µF, 400 V, 15000-hour lifetime at 105°C) with superior inventory (223,420 pcs vs. 3,410 pcs). Both parts maintain identical lead spacing and case diameter.

Q: Can the UPS2D3R3MPD be used in applications requiring higher ripple current? A: The UPS2D3R3MPD is rated for 36 mA ripple current at 120 Hz. For applications exceeding this specification, upgraded parts such as EKXE401ELL3R3MHB5D (50 mA @ 120 Hz, 125 mA @ 100 kHz) or 400LLE3R3MEFC8X11.5 (47 mA @ 120 Hz, 94 mA @ 100 kHz) provide higher ripple current capability.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All substitute parts listed are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the impact of selecting a part with extended lifetime (15000 hours vs. 2000 hours)? A: Extended lifetime parts (ULD2G3R3MPD, 400LLE3R3MEFC8X11.5) provide improved reliability and reduced failure risk over the system operational life. These parts are suitable for applications requiring high availability or extended service intervals. The higher voltage rating (400 V) provides additional design margin.

Q: Can UPW2D3R3MPD be used as a drop-in replacement? A: UPW2D3R3MPD is mechanically compatible with identical lead spacing (0.138", 4.60 mm) and case diameter (0.315", 8.00 mm). The reduced height (0.453" vs. 0.512") provides space advantage. The improved lifetime (3000 hours vs. 2000 hours at 105°C) makes it a suitable upgrade for the original UPS2D3R3MPD.
