Engineering Selection Recommendations

The EEU-ED2W150 is the qualified substitute for the KXG450VB15RM12X25LL based on the following factors:

Product Status: The KXG450VB15RM12X25LL is obsolete, while the EEU-ED2W150 maintains active product status, ensuring long-term availability and supply chain continuity.

Compliance: The EEU-ED2W150 is ROHS3 compliant, whereas the original part is RoHS non-compliant. This compliance difference is significant for applications subject to RoHS regulations.

Electrical Equivalence: Both parts share identical capacitance (15 µF), voltage rating (450 V), tolerance (±20%), operating temperature range (-25°C ~ 105°C), and lifetime rating (10,000 Hrs @ 105°C).

Mechanical Compatibility: Lead spacing, diameter, height, and mounting type are identical, ensuring direct board-level compatibility without PCB redesign.

Ripple Current: The EEU-ED2W150 exhibits slightly lower ripple current ratings (224 mA @ 120 Hz and 560 mA @ 100 kHz) compared to the original part (240 mA @ 120 Hz and 600 mA @ 100 kHz). These differences remain within acceptable operational margins for general-purpose applications.

Frequently Asked Questions (FAQ)

Q: Can the EEU-ED2W150 be used as a direct replacement for the KXG450VB15RM12X25LL?

A: Yes. The EEU-ED2W150 meets all specified electrical and mechanical parameters. Both parts are 15 µF, 450 V, ±20% tolerance aluminum electrolytic capacitors with identical physical dimensions and through-hole radial mounting configuration.

Q: What is the difference in ripple current between these parts?

A: The KXG450VB15RM12X25LL is rated for 240 mA @ 120 Hz and 600 mA @ 100 kHz. The EEU-ED2W150 is rated for 224 mA @ 120 Hz and 560 mA @ 100 kHz. Both ratings are suitable for general-purpose applications.

Q: Does the RoHS compliance difference affect substitution?

A: The EEU-ED2W150 is ROHS3 compliant while the KXG450VB15RM12X25LL is RoHS non-compliant. For applications subject to RoHS regulations, the EEU-ED2W150 is the appropriate choice. For legacy systems without RoHS requirements, both parts are functionally equivalent.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical lead spacing (0.197" / 5.00 mm), diameter (0.492" / 12.50 mm), and height (0.984" / 25.00 mm). No PCB modifications are required for substitution.

Q: What is the product status difference?

A: The KXG450VB15RM12X25LL is obsolete and no longer manufactured. The EEU-ED2W150 is an active product with ongoing manufacturing and supply availability.

Q: Are the operating temperature ranges the same?

A: Yes. Both parts operate across the identical temperature range of -25°C to 105°C with a rated lifetime of 10,000 hours at 105°C.
