Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalent): UVZ2C4R7MED is the parametric equivalent with identical 160 V voltage rating and matching electrical characteristics. This part maintains the original design specifications while providing ROHS3 compliance and is suitable for direct substitution in existing designs.

For Upgraded Performance: Active-status alternatives from Rubycon and Chemi-Con offer higher voltage ratings (200 V or 250 V) with improved reliability metrics. The Rubycon 200LLE series provides extended lifetime (12000 Hrs @ 105°C) compared to the original 1000-hour rating. These upgrades are electrically compatible and physically fit within the same PCB footprint, with maximum height of 0.512" (13.00 mm) remaining within typical board clearance tolerances.

For Immediate Availability: Active-status parts with current production ensure supply chain continuity. Rubycon 200LEX4.7MEFC6.3X11 and 200LLE4R7MEFC6.3X11 offer the highest inventory levels (3439 and 7792 units respectively) with ROHS3 compliance and proven reliability in general-purpose applications.

All recommended substitutes maintain identical lead spacing (0.098" / 2.50 mm), case diameter (0.248" / 6.30 mm), and through-hole mounting compatibility with the original MALREKB05BA147M00K design.

Frequently Asked Questions (FAQ)

Q: Can I use a 200 V rated capacitor in place of the 160 V original? A: Yes. Higher voltage-rated capacitors are electrically compatible and provide design margin. All 200 V and 250 V substitutes listed maintain identical physical dimensions and lead spacing, ensuring PCB compatibility without layout modifications.

Q: What is the difference between the Rubycon LEX and LLE series? A: Both are 4.7 µF 200 V radial capacitors with identical physical dimensions. The LLE series provides extended lifetime (12000 Hrs @ 105°C) compared to LEX (4000 Hrs @ 125°C). Selection depends on application lifetime requirements.

Q: Are obsolete-status parts acceptable for new designs? A: Obsolete parts (UVY2D4R7MED, UVY2E4R7MED, UVZ2C4R7MED) have limited future availability. For new production designs, active-status alternatives from Rubycon (200LEX, 200LLE, 200PX series) or Chemi-Con (EKMQ series) are recommended to ensure long-term supply continuity.

Q: Will the substitute parts fit my existing PCB without modification? A: Yes. All substitute parts maintain the same lead spacing (0.098" / 2.50 mm) and case diameter (0.248" / 6.30 mm). Maximum height is 0.512" (13.00 mm), which accommodates standard through-hole PCB designs. No layout changes are required.

Q: What is the significance of the ±20% tolerance specification? A: The ±20% tolerance applies to all listed substitutes and the original part. This tolerance is standard for aluminum electrolytic capacitors in general-purpose applications and does not affect substitution compatibility.

Q: How do I select between multiple active substitutes? A: Selection criteria include: (1) voltage rating requirement (160 V minimum), (2) lifetime specification (1000 Hrs minimum @ 105°C), (3) ripple current capability (34 mA minimum @ 120 Hz), and (4) inventory availability. Rubycon 200LLE4R7MEFC6.3X11 offers the best combination of extended lifetime and current availability.
