Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters:

Capacitance value: 47 µF (exact match required)
Voltage rating: 250 V (exact match required)
Tolerance: ±20% (exact match required)
Mounting type: Through Hole (exact match required)
Package type: Radial, Can (exact match required)
Operating temperature range: -25°C ~ 105°C (exact match required)

Substitute parts are grouped into two categories based on physical dimensions and lead spacing compatibility:

Category A (Direct Footprint Match): Parts with 0.197" (5.00mm) lead spacing and 0.492" (12.50mm) case diameter. These parts maintain identical PCB hole positioning and can be used as direct replacements without layout modifications.

Category B (Alternate Footprint): Parts with 0.295" (7.50mm) lead spacing and 0.630" (16.00mm) case diameter. These parts require PCB layout verification before substitution due to different hole spacing and case dimensions.

Engineering Selection Recommendations

For Direct Footprint Replacement (0.197" Lead Spacing, 0.492" Case Diameter):

EEU-ED2E470 and EEU-ED2E470B are the primary substitutes. Both are active products with ROHS3 compliance and offer extended lifetime (10000 hours at 105°C) compared to the original 5000-hour rating. These parts maintain identical lead spacing and case diameter, requiring no PCB layout modifications. EEU-ED2E470B is available in Cut Tape packaging, while EEU-ED2E470 is supplied in bulk.

EEU-EB2E470 provides an alternative with 5000-hour lifetime matching the original part specification. This part is active and ROHS3 compliant with slightly higher ripple current capability (710 mA at 100 kHz versus 700 mA).

ECA-2EHG470 and ECA-2EHG470B are active Panasonic alternatives with identical physical dimensions. These parts carry a reduced lifetime specification (2000 hours at 105°C) and lower ripple current ratings (345 mA at 100 kHz). Selection of these parts requires application review to confirm lifetime adequacy.

For Alternate Footprint (0.295" Lead Spacing, 0.630" Case Diameter):

UCA2E470MHD6 is a Nichicon alternative with extended lifetime (12000 hours at 105°C) and improved ripple current performance. This part requires PCB layout verification due to different hole spacing and larger case diameter.

EEU-EB2E470S and EEU-ED2E470S/EEU-ED2E470SB are Panasonic alternatives with the same alternate footprint. EEU-ED2E470S and EEU-ED2E470SB offer 10000-hour lifetime with superior ripple current ratings (990 mA at 100 kHz).

For Constrained Ripple Current Applications:

UPT2E470MPD is an active Nichicon product with direct footprint compatibility but reduced ripple current capability (432 mA at 10 kHz). This part is suitable only for applications with lower ripple current demands.

Frequently Asked Questions (FAQ)

Q: Can I use EEU-ED2E470 as a direct replacement for UPB2E470MHD?

A: Yes. Both parts share identical lead spacing (0.197" / 5.00mm), case diameter (0.492" / 12.50mm), capacitance (47 µF), voltage rating (250 V), tolerance (±20%), and operating temperature range (-25°C to 105°C). EEU-ED2E470 is an active product with ROHS3 compliance and extended lifetime (10000 hours at 105°C). No PCB modifications are required.

Q: What is the difference between EEU-ED2E470 and EEU-ED2E470B?

A: Both parts are electrically and mechanically identical. The difference is packaging: EEU-ED2E470 is supplied in bulk, while EEU-ED2E470B is supplied in Cut Tape (CT) format. Selection depends on procurement and assembly process requirements.

Q: Why do some substitutes have different case diameters?

A: Parts with 0.295" (7.50mm) lead spacing and 0.630" (16.00mm) case diameter represent an alternate footprint. These parts require PCB layout verification before use, as hole spacing and component placement differ from the original design. Verify PCB hole positioning and clearances before substitution.

Q: Can I use ECA-2EHG470 if my application requires 5000-hour lifetime?

A: No. ECA-2EHG470 and ECA-2EHG470B are rated for 2000 hours at 105°C, which does not meet the 5000-hour requirement of the original part. Use EEU-EB2E470, EEU-ED2E470, or equivalent parts with matching or extended lifetime specifications.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts carry ROHS3 compliance certification. The original UPB2E470MHD is classified as REACH Unaffected. Verify compliance requirements for your specific application and regulatory jurisdiction.

Q: What is the impact of different ripple current ratings?

A: Ripple current rating indicates the maximum AC current the capacitor can handle at specified frequency without exceeding temperature limits. Parts with lower ripple current ratings (such as ECA-2EHG470 at 345 mA at 100 kHz) are suitable only for applications with lower ripple current demands. For applications requiring the original 700 mA ripple current at 100 kHz, use EEU-EB2E470 (710 mA) or EEU-ED2E470 (920 mA).

Q: Can I use UPT2E470MPD as a substitute?

A: UPT2E470MPD maintains direct footprint compatibility and is an active product with ROHS3 compliance. However, its ripple current capability (432 mA at 10 kHz) is significantly lower than the original part (700 mA at 100 kHz). Use this part only if your application operates at lower ripple current levels.
