EEU-ED2W150B Equivalent & Substitute Parts

Part Overview

The EEU-ED2W150B is a 15 µF, 450 V aluminum electrolytic capacitor in radial configuration manufactured by Panasonic Electronic Components. This through-hole component is rated for 10,000 hours at 105°C and is designed for general-purpose applications requiring stable capacitance and ripple current handling. The part is Active status and ROHS3 compliant. Substitute parts may be required due to inventory constraints, packaging preferences, or application-specific performance requirements such as extended lifetime or higher voltage ratings.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters: capacitance value (15 µF), rated voltage (450 V minimum), tolerance (±20%), lead spacing (5.00 mm), mounting type (through hole), and package configuration (radial can). Parts are grouped into three categories:

Direct Substitutes maintain identical electrical specifications and physical dimensions, differing only in packaging format (tape & box versus bulk).

Similar Substitutes share core electrical ratings but may vary in secondary performance characteristics such as ripple current capacity or lifetime rating, while maintaining mechanical compatibility.

Upgrade Substitutes exceed the original specifications in voltage rating or lifetime, providing enhanced performance margins while maintaining physical and electrical compatibility.

Engineering Selection Recommendations

EEU-ED2W150 (Direct Substitute): Select this part when packaging format flexibility is acceptable. Identical electrical and thermal specifications to the main part with equivalent performance. Bulk packaging may offer cost advantages for high-volume applications. Height difference of 0.079" (2.00 mm) is negligible for most PCB layouts.

EEU-EE2W150 (Similar Substitute): This Panasonic alternative maintains all critical electrical parameters and physical compatibility. Higher ripple current capacity (273 mA @ 120 Hz and 780 mA @ 100 kHz versus 224 mA and 560 mA respectively) provides additional performance margin. Suitable for applications with elevated ripple current demands. Moisture Sensitivity Level is Not Applicable, indicating enhanced environmental stability.

UCY2H150MHD1TO (Upgrade Substitute): This Nichicon part offers enhanced specifications with 500 V rated voltage (50 V higher than original) and extended lifetime of 12,000 hours at 105°C. Extended operating temperature range (-40°C to 105°C) accommodates broader environmental conditions. REACH Affected status requires compliance verification for specific applications. Recommended for designs requiring higher voltage margins or extended service life.

UPT2W150MPD (Similar Substitute): This Nichicon option maintains voltage and capacitance ratings but features reduced lifetime (5,000 hours at 105°C) and lower ripple current specifications. Physical dimensions differ: 0.394" diameter (10.00 mm) and 1.299" height (33.00 mm). Select only when space constraints permit increased height and reduced ripple current handling is acceptable.

Frequently Asked Questions (FAQ)

Q: Can EEU-ED2W150B be replaced with EEU-ED2W150? A: Yes. Both parts share identical electrical specifications (15 µF, 450 V, ±20%, 10,000 Hrs @ 105°C) and mechanical compatibility (5.00 mm lead spacing, 12.50 mm diameter). The only difference is packaging format (tape & box versus bulk). Height varies by 2.00 mm, which is typically inconsequential for PCB design.

Q: What is the advantage of UCY2H150MHD1TO over the original part? A: The Nichicon UCY2H150MHD1TO provides two performance enhancements: 50 V higher rated voltage (500 V versus 450 V) and 2,000 additional hours of lifetime at 105°C (12,000 versus 10,000 hours). These upgrades provide greater safety margins and extended operational life. Operating temperature range extends to -40°C, supporting colder environments.

Q: Is UPT2W150MPD suitable as a direct replacement? A: UPT2W150MPD is mechanically compatible but exhibits reduced performance. Lifetime is halved (5,000 versus 10,000 hours at 105°C), and ripple current capacity is significantly lower (150 mA @ 120 Hz versus 224 mA). Physical dimensions differ substantially: 10.00 mm diameter and 33.00 mm height. Use only when application requirements permit reduced lifetime and ripple current handling, and when increased height fits the PCB layout.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance. UCY2H150MHD1TO carries REACH Affected status, requiring compliance verification for specific regulatory jurisdictions or end-use applications.

Q: What is the impact of different packaging formats? A: Packaging format (tape & box, bulk, or cut tape) affects supply chain logistics and component handling but does not alter electrical or mechanical performance. Selection depends on assembly process requirements and inventory management preferences.
