UPW2D4R7MPD Equivalent & Substitute Parts

Part Overview

The UPW2D4R7MPD is a 4.7 µF, 200 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete and rated for 5000 hours at 105°C. Due to its obsolete status, equivalent and substitute parts from active manufacturers or alternative series are necessary for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the UPW2D4R7MPD is determined by the following criteria:

Primary Substitution Parameters:

• Capacitance: 4.7 µF (exact match required)
• Voltage Rating: 200 V minimum (equal or higher acceptable)
• Tolerance: ±20% (standard for this category)
• Polarization: Polar (required for electrolytic type)
• Mounting Type: Through Hole (required for PCB compatibility)
• Package Type: Radial, Can (required for form factor compatibility)
• Operating Temperature: -40°C ~ 105°C (minimum requirement)

Secondary Considerations:

• Lead Spacing: 0.197" (5.00mm) preferred for direct PCB fit
• Case Diameter: 0.394" (10.00mm) preferred for space constraints
• Lifetime @ 105°C: 5000 Hrs preferred; lower ratings acceptable if application permits
• RoHS3 Compliance: Required for regulatory compliance

Substitutes are grouped by their relationship to the main part: MFR Recommended (higher voltage rating), Upgrade (same series, higher voltage), and Similar (alternative manufacturers or series with compatible electrical and mechanical parameters).

Parameter Comparison

Engineering Selection Recommendations

For Direct PCB Replacement (Preferred): UPW2E4R7MPD (Nichicon) maintains identical lead spacing (0.197", 5.00mm) and case diameter (0.394", 10.00mm) as the original UPW2D4R7MPD. This part is from the same UPW series and provides 5000 hours lifetime at 105°C with 250 V rating, exceeding the original 200 V specification. Product status is obsolete; however, inventory availability is confirmed.

For Active Product Status: MAL214232478E3 or MAL214252478E3 (Vishay Beyschlag/Draloric/BC Components) are active products meeting all electrical specifications. Both are 142 RHS series aluminum electrolytic capacitors with 4.7 µF, 200 V, ±20% tolerance, and 2500 hours lifetime at 105°C. Lead spacing differs (0.197" or 0.138" depending on variant), requiring PCB layout verification.

For Higher Voltage Margin: UVZ2V4R7MPD (Nichicon) provides 350 V rating with identical lead spacing and case diameter. Lifetime is reduced to 2000 hours at 105°C; this part is not recommended for new designs but remains available.

For Compact Form Factor: UVY2D4R7MED (Nichicon) offers reduced case diameter (0.248", 6.30mm) and lead spacing (0.098", 2.50mm) for space-constrained applications. Lifetime is 1000 hours at 105°C; PCB layout modification is required.

All recommended substitutes are ROHS3 compliant and operate within -40°C to 105°C temperature range.

Frequently Asked Questions (FAQ)

Q: Can UPW2E4R7MPD directly replace UPW2D4R7MPD on existing PCBs? A: Yes. UPW2E4R7MPD maintains identical lead spacing (0.197", 5.00mm) and case diameter (0.394", 10.00mm). The 250 V rating exceeds the original 200 V specification and is electrically compatible. Both are through-hole radial can packages.

Q: What is the difference between MAL214232478E3 and MAL214252478E3? A: Both are Vishay 142 RHS series, 4.7 µF, 200 V, ±20% tolerance capacitors with 2500 hours lifetime at 105°C. The primary difference is lead spacing: MAL214232478E3 has 0.197" (5.00mm) spacing, while MAL214252478E3 has 0.138" (4.60mm) spacing. Case diameter is 0.315" (8.00mm) for both. PCB layout must accommodate the selected lead spacing.

Q: Why is UVZ2V4R7MPD marked "Not For New Designs"? A: UVZ2V4R7MPD is from an obsolete series. Although it meets electrical specifications with 350 V rating and identical mechanical dimensions, Nichicon has discontinued this line. For new designs, active alternatives such as MAL214232478E3 or MAL214252478E3 are preferred.

Q: Can UVY2D4R7MED be used as a substitute despite lower lifetime rating? A: UVY2D4R7MED provides 1000 hours at 105°C compared to the original 5000 hours. Substitution is possible only if application duty cycle and thermal environment permit reduced lifetime. Lead spacing (0.098", 2.50mm) and case diameter (0.248", 6.30mm) differ significantly, requiring PCB redesign.

Q: Are all substitutes ROHS3 compliant? A: Yes. All listed substitutes are ROHS3 compliant and suitable for applications requiring regulatory compliance.

Q: What is the impact of different lead spacings on PCB compatibility? A: Lead spacing determines through-hole pad positioning on the PCB. UPW2D4R7MPD and UPW2E4R7MPD both use 0.197" (5.00mm) spacing and are directly interchangeable. Alternatives with 0.138" (4.60mm) or 0.098" (2.50mm) spacing require PCB layout modification or new board design.
