Engineering Selection Recommendations

Preferred Substitutes (Nichicon Active Status):

URS2A470MPD, UVR2A470MPD1AA, and UVR2A470MPD1CM are direct Nichicon replacements with Active product status. These parts maintain identical electrical and mechanical specifications to the original UVR2A470MPD, ensuring drop-in compatibility. All three carry ROHS3 compliance and are suitable for applications requiring current manufacturer support and traceability.

Alternative Manufacturer Options (Active Status, Enhanced Performance):

476CKE100M (Cornell Dubilier / Illinois Capacitor) and 476KBM100MGU (Cornell Dubilier / Illinois Capacitor) are Active products with identical capacitance, voltage, and tolerance ratings. Both feature extended operating temperature ranges (-40°C ~ 105°C) and higher lifetime ratings (2000 Hrs @ 105°C and 7000 Hrs @ 105°C respectively), providing enhanced thermal performance. Mechanical footprint is identical. Both are ROHS3 compliant.

B41821B9476M000 (EPCOS - TDK Electronics) is an Active product with matching electrical specifications and ROHS3 compliance. Height is 0.531" (14.60 mm), which is 0.020" shorter than the original, allowing for tighter PCB layouts. Operating temperature range matches the original (-40°C ~ 85°C).

Mechanical Compatibility Considerations:

UKL2A470MPD has a height of 0.846" (21.50 mm), significantly taller than the original 0.551" (14.00 mm). This part is suitable only if PCB layout permits increased vertical clearance.

UVK2A470MPD has reduced lead spacing (0.138" vs. 0.197") and smaller case diameter (0.315" vs. 0.394"). This part requires PCB footprint modification and is not a direct drop-in replacement.

Obsolete Status Consideration:

100ZL47MEFC10X12.5 (Rubycon) carries Obsolete status and should be avoided for new procurement unless existing inventory is available and acceptable for legacy system support.

Frequently Asked Questions (FAQ)

Q: Can I substitute URS2A470MPD for UVR2A470MPD in my circuit?

A: Yes. URS2A470MPD is a direct Nichicon replacement with identical capacitance (47 µF), voltage rating (100 V), tolerance (±20%), operating temperature range (-40°C ~ 85°C), and mechanical footprint (0.197" lead spacing, 0.394" case diameter, 0.551" height). The primary difference is product status: URS2A470MPD is Active, while UVR2A470MPD is Not For New Designs. Both are ROHS3 compliant.

Q: What is the difference between UVR2A470MPD1AA, UVR2A470MPD1CM, and UVR2A470MPD1CV?

A: All three are Nichicon UVR series variants with identical electrical specifications (47 µF, 100 V, ±20%, 2000 Hrs @ 85°C) and mechanical dimensions. The suffix designations (1AA, 1CM, 1CV) indicate internal manufacturing or packaging variations. UVR2A470MPD1AA and UVR2A470MPD1CM carry Active status, while UVR2A470MPD1CV is Not For New Designs. All are mechanically and electrically interchangeable.

Q: Can I use 476KBM100MGU instead of UVR2A470MPD?

A: Yes, with performance advantages. 476KBM100MGU (Cornell Dubilier / Illinois Capacitor) matches all critical parameters: 47 µF capacitance, 100 V voltage rating, ±20% tolerance, identical mechanical footprint (0.197" lead spacing, 0.394" case diameter, 0.551" height), and Through Hole mounting. It exceeds the original in lifetime rating (7000 Hrs @ 105°C vs. 2000 Hrs @ 85°C) and operating temperature range (-40°C ~ 105°C vs. -40°C ~ 85°C). Both are ROHS3 compliant. This is a direct drop-in replacement with enhanced thermal performance.

Q: Why is UKL2A470MPD not recommended as a direct substitute?

A: While UKL2A470MPD matches all electrical specifications, its height is 0.846" (21.50 mm) compared to the original 0.551" (14.00 mm). This 0.295" difference requires verification of available PCB clearance above the component. If vertical space is constrained, this part will not fit without PCB redesign or component relocation.

Q: Is B41821B9476M000 a suitable replacement?

A: Yes. B41821B9476M000 (EPCOS - TDK Electronics) is an Active product with matching capacitance, voltage, tolerance, and operating temperature range. Its height is 0.531" (14.60 mm), which is 0.020" shorter than the original, allowing for tighter PCB layouts without clearance issues. Mechanical footprint is compatible. ROHS3 compliant.

Q: Can I use UVK2A470MPD as a substitute?

A: UVK2A470MPD is not a direct drop-in replacement. While it matches electrical specifications, it has reduced lead spacing (0.138" vs. 0.197") and smaller case diameter (0.315" vs. 0.394"). PCB footprint modification is required. Use only if PCB redesign is acceptable.

Q: What does "Not For New Designs" status mean?

A: "Not For New Designs" indicates the part has been superseded in the manufacturer's product line. It remains available for existing inventory and legacy system support but is not recommended for new circuit designs. For new designs, select Active status alternatives such as URS2A470MPD, UVR2A470MPD1AA, or UVR2A470MPD1CM.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts carry ROHS3 compliance, matching the original UVR2A470MPD. This ensures compatibility with environmental and regulatory requirements.
