EEU-ED2E470B Equivalent & Substitute Parts

Part Overview

The EEU-ED2E470B is a 47 µF, 250 V aluminum electrolytic capacitor in radial configuration manufactured by Panasonic Electronic Components. This part operates across a temperature range of -25°C to 105°C with a rated lifetime of 10,000 hours at 105°C, designed for general-purpose applications requiring stable capacitance and ripple current handling. The part is currently active in production and ROHS3 compliant.

Equivalent and substitute parts are necessary when the original part becomes unavailable, when packaging requirements change, or when design specifications allow for alternative components with compatible electrical and mechanical characteristics. Substitutes must maintain the same capacitance value, voltage rating, tolerance, and physical mounting compatibility while meeting application ripple current and thermal requirements.

Engineering Selection Recommendations

For Direct Replacement (No PCB Modification Required):

EEU-ED2E470 is the primary direct substitute. It maintains identical electrical specifications and lead spacing with the original part. The height difference (0.984" vs. 1.063") is within typical PCB clearance tolerances for most applications. This part is Active in production status and ROHS3 compliant.

EEU-EE2E470 provides equivalent electrical performance with superior ripple current handling (1.29 A @ 100 kHz vs. 920 mA). It maintains identical lead spacing and case diameter, making it a direct mechanical fit. This part is Active in production and ROHS3 compliant.

For Applications Requiring Extended Lifetime:

UCY2V470MHD1TO (Nichicon) offers 12,000-hour lifetime at 105°C with a higher 350 V voltage rating. This part maintains identical lead spacing and case diameter. It is Active in production status and ROHS3 compliant. The higher voltage rating provides additional design margin without affecting physical compatibility.

UCA2E470MHD1TO (Nichicon) provides 12,000-hour lifetime at 250 V with identical lead spacing and case diameter. However, this part is marked "Not For New Designs," limiting its suitability for new product development.

For Applications with Reduced Lifetime Requirements:

ECA-2EHG470 and ECA-2EHG470B are suitable for applications where 2,000-hour lifetime at 105°C is acceptable. Both maintain identical lead spacing and case diameter. These parts are Active in production and ROHS3 compliant. Ripple current ratings are reduced (230 mA @ 120 Hz, 345 mA @ 100 kHz), requiring verification against application requirements.

For Applications Requiring PCB Layout Modification:

EEU-ED2E470S, EEU-EB2E470S, and UCA2E470MHD6 feature different lead spacing (0.295" vs. 0.197") and larger case diameter (0.630" vs. 0.492"). These parts require PCB footprint redesign and are suitable only when physical space constraints are not limiting factors. EEU-ED2E470S and EEU-EB2E470S are Active in production; UCA2E470MHD6 is Obsolete.

Parts Not Recommended for New Designs:

UCA2E470MHD1TO carries "Not For New Designs" status and should be avoided in new product development. UCA2E470MHD6 is Obsolete and should not be used. UPT2E470MPD has reduced ripple current capability (270 mA @ 120 Hz, 432 mA @ 10 kHz) and different case diameter, limiting its applicability.

Frequently Asked Questions (FAQ)

Q: Can EEU-ED2E470 replace EEU-ED2E470B directly without PCB modification?

A: Yes. Both parts have identical capacitance (47 µF), voltage rating (250 V), tolerance (±20%), lead spacing (0.197" / 5.00mm), and case diameter (0.492" / 12.50mm). The height difference (0.984" vs. 1.063") is typically accommodated within standard PCB clearance specifications. Verify clearance in your specific application.

Q: What is the difference between "Direct," "Similar," and "Upgrade" substitute classifications?

A: Direct substitutes maintain identical electrical and mechanical specifications with only packaging differences. Similar substitutes share the same capacitance, voltage, and tolerance but may differ in lifetime, ripple current, or physical dimensions. Upgrade substitutes offer improved specifications (higher voltage rating, extended lifetime) while maintaining mechanical compatibility.

Q: Can I use ECA-2EHG470 in place of EEU-ED2E470B?

A: Mechanical compatibility is confirmed (identical lead spacing and case diameter). However, electrical performance differs: ECA-2EHG470 has 2,000-hour lifetime versus 10,000 hours, and reduced ripple current ratings (230 mA @ 120 Hz vs. 368 mA). Use only if your application tolerates reduced lifetime and lower ripple current specifications.

Q: Why do some substitutes have different lead spacing and case diameter?

A: Parts with 0.295" (7.50mm) lead spacing and 0.630" (16.00mm) case diameter belong to different physical form factors within the same capacitance and voltage family. These require PCB footprint redesign and are suitable only when layout constraints permit larger component spacing.

Q: Is UCY2V470MHD1TO a suitable upgrade for EEU-ED2E470B?

A: Yes, for applications where higher voltage margin is beneficial. UCY2V470MHD1TO maintains identical lead spacing (0.197" / 5.00mm) and case diameter (0.492" / 12.50mm), with 350 V rating versus 250 V. It offers extended lifetime (12,000 hrs) and superior ripple current handling (1.02 A @ 100 kHz). The higher voltage rating does not affect physical compatibility or electrical performance in 250 V applications.

Q: What does "Not For New Designs" status mean for UCA2E470MHD1TO?

A: This designation indicates the manufacturer is discontinuing the part and recommends against using it in new product development. While the part may still be available in inventory, it should not be selected for designs with long production lifecycles or future revisions.

Q: Can I use UPT2E470MPD as a substitute?

A: UPT2E470MPD maintains identical lead spacing (0.197" / 5.00mm) but has a smaller case diameter (0.394" vs. 0.492"). More critically, ripple current ratings are significantly reduced (270 mA @ 120 Hz vs. 368 mA, and 432 mA @ 10 kHz vs. 920 mA @ 100 kHz). Use only if your application requires lower ripple current and can accommodate the smaller case diameter.

Q: Are all listed substitutes ROHS3 compliant?

A: Yes. All parts listed carry ROHS3 compliance certification. Compliance status is consistent across the substitute list.
