Engineering Selection Recommendations

The EKXG401ELL100MJ20S is a direct parametric equivalent to the KXG400VB10RM10X20LL. All electrical and mechanical specifications are identical, ensuring functional compatibility in circuit applications.

The primary distinction between these parts is product status and regulatory compliance. The KXG400VB10RM10X20LL is obsolete, while the EKXG401ELL100MJ20S maintains active product status from Chemi-Con. Additionally, the EKXG401ELL100MJ20S is ROHS3 compliant, whereas the original part is RoHS non-compliant. For new designs or systems requiring regulatory compliance with modern environmental standards, the EKXG401ELL100MJ20S is the appropriate selection.

Both parts are manufactured by Chemi-Con within the KXG series and share identical electrical performance characteristics, thermal ratings, and physical dimensions. Selection between these parts should be based on supply availability, compliance requirements, and product lifecycle considerations.

Frequently Asked Questions (FAQ)

Q: Can the EKXG401ELL100MJ20S be used as a direct replacement for the KXG400VB10RM10X20LL?

A: Yes. The EKXG401ELL100MJ20S is a parametric equivalent with identical capacitance (10 µF), voltage rating (400 V), tolerance (±20%), thermal lifetime (8000 Hrs @ 105°C), operating temperature range (-40°C ~ 105°C), ripple current specifications, and physical dimensions. Both are through-hole radial can packages with 5.00 mm lead spacing, 10.00 mm diameter, and 20.00 mm height. Direct substitution is supported.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and RoHS compliance. The KXG400VB10RM10X20LL is obsolete and RoHS non-compliant. The EKXG401ELL100MJ20S is an active product and ROHS3 compliant. All electrical and mechanical parameters are identical.

Q: Are there any compatibility concerns with PCB layout or circuit design?

A: No. Both parts share identical lead spacing (5.00 mm), package dimensions (10.00 mm diameter, 20.00 mm height), and mounting type (through-hole radial). PCB footprints and circuit designs require no modification.
