Engineering Selection Recommendations

EKXG451ELL220ML20S (Chemi-Con KXG Series)

This substitute is a direct parametric equivalent from the same manufacturer and series as the main part. All electrical and mechanical specifications are identical. The EKXG451ELL220ML20S carries Active product status and is ROHS3 compliant, providing improved regulatory alignment compared to the obsolete main part. Inventory availability is 2,100 units. This part is the preferred substitute when maintaining design continuity within the Chemi-Con KXG product family.

EEU-ED2W220S (Panasonic Electronic Components ED Series)

This substitute meets all required electrical and mechanical parameters and is manufactured by Panasonic Electronic Components. The EEU-ED2W220S is Active and ROHS3 compliant. Ripple current specifications are slightly lower (272 mA @ 120 Hz and 680 mA @ 100 kHz compared to 290 mA and 725 mA respectively), remaining within acceptable operating margins for general-purpose applications. Inventory availability is 4,400 units. This part is suitable for applications where cross-manufacturer substitution is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the EKXG451ELL220ML20S be used as a direct replacement for the KXG450VB22RM16X20LL?

A: Yes. The EKXG451ELL220ML20S matches all electrical parameters (22 µF, 450 V, ±20% tolerance, 10,000 Hrs @ 105°C) and mechanical parameters (lead spacing, case diameter, height, through-hole mounting). Both are Chemi-Con products in the KXG series.

Q: What is the difference in ripple current between the main part and the EEU-ED2W220S?

A: The EEU-ED2W220S has lower ripple current ratings: 272 mA @ 120 Hz (versus 290 mA) and 680 mA @ 100 kHz (versus 725 mA). These differences are within acceptable operating margins for general-purpose applications with identical voltage and capacitance ratings.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both EKXG451ELL220ML20S and EEU-ED2W220S are ROHS3 compliant, whereas the main part KXG450VB22RM16X20LL is RoHS non-compliant. This represents an improvement in regulatory compliance.

Q: Can I use either substitute interchangeably?

A: Both substitutes meet the specified electrical and mechanical parameters. Selection between them depends on manufacturer preference, inventory availability, and application-specific ripple current requirements. The EKXG451ELL220ML20S maintains the same manufacturer and series as the original part.

Q: What is the lead spacing for these capacitors?

A: All three parts (main and both substitutes) have identical lead spacing of 0.295" (7.50 mm), ensuring compatibility with existing PCB layouts designed for the KXG450VB22RM16X20LL.

Q: Are there inventory considerations for these parts?

A: The main part KXG450VB22RM16X20LL has 811 units in stock. The EKXG451ELL220ML20S has 2,100 units available, and the EEU-ED2W220S has 4,400 units available, providing multiple sourcing options.
