Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following parameters:

Capacitance: 4.7 µF (exact match required)
Voltage Rating: 400 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Package Type: Radial, Can (exact match required)
Mounting Type: Through Hole (exact match required)
Lead Spacing: 0.197" (5.00 mm) (exact match required)
Case Diameter: 0.394" (10.00 mm) (exact match required)

All listed substitute parts meet these core electrical and mechanical parameters. Variations in lifetime rating, operating temperature range, ripple current specifications, and product status are secondary considerations that do not affect basic substitutability.

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance)

UVY2G4R7MPD (Nichicon) provides parametric equivalence with identical lifetime rating and operating temperature range. This part maintains the same physical footprint and electrical characteristics as the original UAS2G4R7MPD.

For Extended Reliability

ULD2G4R7MPD (Nichicon) and 400LLE4R7MEFC10X12.5 (Rubycon) offer 15000-hour lifetime ratings at 105°C, providing significantly improved reliability over the original 2000-hour specification. Both parts are RoHS3 compliant and maintain the required electrical parameters.

For Active Product Status

400PX4R7M10X12.5, 400PX4R7MEFCT810X12.5 (Rubycon), and all MAL series parts (Vishay Beyschlag/Draloric/BC Components) carry active product status. The Rubycon PX series maintains 2000-hour lifetime, while Vishay MAL series offers 2500 to 3000-hour ratings. Vishay MAL215296473E3, MAL215296475E3, and MAL215296476E3 include AEC-Q200 automotive qualification.

For Enhanced Temperature Performance

400LEX4.7MEFC10X12.5 (Rubycon) extends the operating temperature range to 125°C with 5000-hour lifetime at that temperature, suitable for applications requiring higher thermal margins.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different case height?

A: Case height variation is acceptable provided the lead spacing (0.197" / 5.00 mm) and case diameter (0.394" / 10.00 mm) remain unchanged. Height differences of ±0.02" are within acceptable PCB layout tolerances for through-hole radial capacitors. Verify clearance in your specific application.

Q: What is the difference between Nichicon ULD and UVY series?

A: Both maintain 4.7 µF, 400 V specifications. ULD offers 15000-hour lifetime at 105°C with RoHS3 compliance and REACH affected status. UVY provides 2000-hour lifetime with REACH unaffected status. ULD is preferred for extended-life applications.

Q: Are the Rubycon LEX and LLE series interchangeable?

A: Both are electrically equivalent at 4.7 µF, 400 V. LEX operates to 125°C with 5000-hour lifetime at that temperature. LLE operates to 105°C with 15000-hour lifetime. Selection depends on thermal requirements and desired operational life.

Q: Do Vishay MAL automotive parts require special handling?

A: Vishay MAL215296473E3, MAL215296475E3, and MAL215296476E3 carry AEC-Q200 automotive qualification. They meet automotive reliability standards but do not require special handling beyond standard ESD precautions for electrolytic capacitors.

Q: What is the impact of ripple current differences between parts?

A: Ripple current specifications indicate the maximum AC current the capacitor can handle at specified frequencies. Higher ripple current ratings provide design margin. All listed parts meet or exceed the original UAS2G4R7MPD ripple current specifications at their respective frequency ratings.

Q: Can I substitute based on lifetime rating alone?

A: No. Lifetime rating is a secondary parameter. Substitution requires exact match of capacitance, voltage, tolerance, polarization, package type, mounting type, lead spacing, and case diameter. Lifetime rating and operating temperature range are performance enhancements, not substitution criteria.
