EEU-ED2W100 Equivalent & Substitute Parts

Part Overview

The EEU-ED2W100 is a 10 µF, 450 V aluminum electrolytic capacitor in radial, can package manufactured by Panasonic Electronic Components. This part is rated for 10,000 hours at 105°C and is classified as Active product status. Substitute parts become necessary when the EEU-ED2W100 reaches end-of-life inventory, when design flexibility is required for cost optimization, or when alternative manufacturers' components meet the same electrical and mechanical specifications for your application.

Lead Spacing: 0.197" (5.00 mm)
Case Diameter: 0.492" (12.50 mm)
Mounting Type: Through Hole
Package Type: Radial, Can
Operating Temperature Range: -25°C to 105°C

Engineering Selection Recommendations

For Active Product Status (Recommended for New Designs):

EEU-EE2W100 (Panasonic) is the primary substitute. It matches all critical electrical parameters and maintains the 10,000-hour lifetime rating. The height increase from 0.787" to 0.866" requires PCB layout verification but does not affect electrical performance.

EEU-EB2W100 (Panasonic) is acceptable when cost reduction is prioritized and application lifetime requirements permit 5,000-hour operation. All other parameters remain compatible.

EKMG451ELL100MK20S (Chemi-Con) is acceptable for general-purpose applications where 2,000-hour lifetime is sufficient. This part carries Active status and ROHS3 compliance.

For Obsolete or Legacy Designs:

UCA2W100MHD (Nichicon) offers extended 12,000-hour lifetime but is classified Obsolete. Use only when existing inventory is available and no Active alternatives meet design constraints.

EKXG451ELL100MK20S (Chemi-Con) provides 10,000-hour lifetime with identical case dimensions to the EEU-ED2W100 but is Obsolete. Suitable only for legacy system maintenance.

Not Recommended for New Designs:

UPW2W100MHD, UVY2W100MPD, and UVZ2W100MHD carry either Obsolete or Not For New Designs status. These parts present supply chain risk and should be avoided in new product development.

All substitute candidates maintain ROHS3 compliance and REACH Unaffected status, matching the original part's regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can EEU-EE2W100 replace EEU-ED2W100 directly on the PCB?

A: Electrical substitution is direct. The height difference (0.866" vs. 0.787") requires PCB layout verification. If the PCB has sufficient clearance above the capacitor location, physical substitution is feasible. Verify lead spacing (both 0.197") and case diameter (both 0.492") match your footprint.

Q: What is the impact of reduced lifetime ratings (5,000 or 2,000 hours vs. 10,000 hours)?

A: Lifetime rating indicates the expected operational duration at maximum rated temperature (105°C) before capacitance degradation exceeds tolerance limits. Applications operating continuously at elevated temperatures require matching or exceeding the original lifetime. For intermittent or room-temperature operation, lower lifetime ratings may be acceptable. Consult your thermal analysis and duty cycle requirements.

Q: Why is UPW2W100MHD listed as a substitute if its lead spacing differs?

A: UPW2W100MHD has 0.295" (7.50 mm) lead spacing versus the standard 0.197" (5.00 mm). This part is included in the substitute list but requires PCB redesign and is not a drop-in replacement. It is classified Obsolete and should not be selected for new designs.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed maintain ROHS3 compliance and REACH Unaffected status, matching the regulatory profile of the EEU-ED2W100.

Q: Which substitute offers the best performance upgrade?

A: UCA2W100MHD (Nichicon) provides 12,000-hour lifetime, exceeding the original 10,000-hour rating. However, it is classified Obsolete. For Active products, EEU-EE2W100 maintains the 10,000-hour rating with current availability.

Q: Can I use EKMG451ELL100MK20S in a high-reliability application?

A: EKMG451ELL100MK20S carries only 2,000-hour lifetime at 105°C. High-reliability applications typically require minimum 10,000-hour ratings. This part is suitable only for general-purpose applications with lower lifetime demands.

Q: What is the difference between "Obsolete" and "Not For New Designs" status?

A: Obsolete parts have reached end-of-life and may have limited remaining inventory. Not For New Designs indicates the manufacturer no longer recommends the part for new product development but may still maintain limited stock. Both statuses present supply chain risk for production quantities.
