UPJ2C4R7MPD Equivalent & Substitute Parts

Part Overview

The UPJ2C4R7MPD is a 4.7 µF, 160 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 part features a 5000-hour lifetime rating at 105°C and is suitable for general-purpose applications requiring polar capacitive filtering.

Due to its obsolete status, equivalent and substitute parts are necessary for ongoing maintenance, repair, and legacy system support. Suitable alternatives are available across multiple manufacturers with varying electrical characteristics and reliability ratings.

Engineering Selection Recommendations

Direct Replacement (Same Voltage, Same Lead Spacing):

UVZ2V4R7MPD is the manufacturer-recommended substitute. It maintains identical lead spacing (0.197", 5.00 mm) and case diameter (0.394", 10.00 mm) for direct PCB compatibility. The higher voltage rating (350 V vs. 160 V) provides additional safety margin. However, the reduced lifetime rating (2000 Hrs vs. 5000 Hrs at 105°C) must be evaluated against application requirements.

Enhanced Reliability Upgrades (Higher Voltage, Extended Lifetime):

ULD2G4R7MPD and 400LLE4R7MEFC10X12.5 both offer 400 V ratings with significantly extended lifetimes (15000 Hrs at 105°C). Both maintain the preferred lead spacing and case diameter. ULD2G4R7MPD is a Nichicon product, while 400LLE4R7MEFC10X12.5 is manufactured by Rubycon and carries Active product status. The 400LLE4R7MEFC10X12.5 is preferred for new applications due to its Active status and proven availability.

Compact Form Factor Alternatives (Reduced Physical Dimensions):

UPS2C4R7MPD, UPW2C4R7MPD, UVZ2C4R7MED, and SEK4R7M160ST feature reduced lead spacing (0.098" to 0.138", 2.50 to 4.60 mm) and smaller case diameters (0.248" to 0.315", 6.30 to 8.00 mm). These are suitable only if PCB layout permits the modified footprint. SEK4R7M160ST is the only Active product in this category and is manufactured by Cornell Dubilier Electronics.

Compliance Considerations:

All listed parts are ROHS3 compliant. The ULD2G4R7MPD is REACH Affected; all others are REACH Unaffected. For applications requiring REACH compliance, select from UVZ2V4R7MPD, 400LEX4.7MEFC10X12.5, 400LLE4R7MEFC10X12.5, or SEK4R7M160ST.

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage-rated capacitor as a substitute?

A: Yes. A capacitor rated for higher voltage (e.g., 350 V or 400 V) can replace a 160 V part in the same circuit. The higher voltage rating provides additional safety margin and does not degrade circuit performance. The capacitance value (4.7 µF) and tolerance (±20%) must remain identical.

Q: What is the impact of reduced lifetime rating on substitution?

A: Lifetime rating indicates the expected operational duration at maximum rated temperature (105°C). A part with reduced lifetime (e.g., 2000 Hrs vs. 5000 Hrs) may require more frequent replacement in high-temperature applications. For room-temperature or moderate-temperature operation, the impact is minimal. Evaluate application temperature profiles before selecting a lower-lifetime substitute.

Q: Can I use a substitute with different lead spacing?

A: Lead spacing changes require PCB layout modification. The UPJ2C4R7MPD uses 0.197" (5.00 mm) lead spacing. Substitutes with 0.138" (4.60 mm) or 0.098" (2.50 mm) spacing require new PCB drilling or rework. Direct PCB compatibility is maintained only with substitutes using identical 0.197" (5.00 mm) lead spacing: UVZ2V4R7MPD, ULD2G4R7MPD, 400LEX4.7MEFC10X12.5, and 400LLE4R7MEFC10X12.5.

Q: What is the difference between Nichicon and Rubycon substitutes?

A: Both manufacturers produce equivalent 4.7 µF, 400 V radial aluminum electrolytic capacitors with identical electrical specifications. Rubycon's 400LLE4R7MEFC10X12.5 offers Active product status and extended 15000-hour lifetime at 105°C. Nichicon's ULD2G4R7MPD is classified as Not For New Designs. For new applications, Rubycon is preferred; for legacy system maintenance, either manufacturer is acceptable if inventory is available.

Q: Is the UVZ2V4R7MPD suitable for direct replacement?

A: Yes, UVZ2V4R7MPD is the manufacturer-recommended substitute with identical lead spacing and case diameter. It is electrically compatible and provides higher voltage rating (350 V). The reduced lifetime (2000 Hrs vs. 5000 Hrs at 105°C) is the primary trade-off. For applications operating below 105°C, this reduction has minimal practical impact.

Q: Which substitute offers the best long-term reliability?

A: 400LLE4R7MEFC10X12.5 (Rubycon) and ULD2G4R7MPD (Nichicon) both offer 15000-hour lifetime ratings at 105°C, representing a threefold improvement over the original UPJ2C4R7MPD. The 400LLE4R7MEFC10X12.5 is preferred due to Active product status and higher inventory availability (44011 units in stock).

Q: Can I use SEK4R7M160ST as a substitute?

A: SEK4R7M160ST is electrically equivalent (4.7 µF, 160 V, ±20%) and is manufactured by Cornell Dubilier Electronics with Active product status. However, it uses 0.098" (2.50 mm) lead spacing and 0.248" (6.30 mm) case diameter, requiring PCB modification. Use only if layout constraints permit the compact form factor.
