Substitute Part Grouping Explanation

Substitution of the KXG350VB22RM12X20LL is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters for Substitution:

Capacitance value: 22 µF (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Lead spacing: 0.197" (5.00 mm) (exact match required)
Case diameter: 0.492" (12.50 mm) (exact match required)
Height: 0.787" (20.00 mm) (exact match required)
Mounting type: Through Hole (exact match required)
Package type: Radial, Can (exact match required)
Operating temperature range: -40°C ~ 105°C (exact match required)
Lifetime: 10,000 Hrs @ 105°C (exact match required)
Ripple current specifications: 260 mA @ 120 Hz and 650 mA @ 100 kHz (exact match required)

Voltage Rating Substitution Logic: Substitute parts may have equal or higher voltage ratings than the original part. A 350 V rated capacitor can be replaced with a 400 V rated capacitor of identical capacitance and all other electrical and mechanical parameters, as the higher voltage rating provides equivalent or superior performance in circuits designed for 350 V operation.

Engineering Selection Recommendations

EKXG401ELL220MK20S (Upgrade Substitute): This part is classified as an upgrade substitute due to its higher voltage rating of 400 V compared to the original 350 V specification. All electrical and mechanical parameters remain identical to the main part. The EKXG401ELL220MK20S carries Active product status and is ROHS3 compliant, providing improved regulatory compliance and long-term availability. This part is suitable for direct replacement in applications where the circuit design permits operation at the higher voltage rating.

EKXG351ELL220MK20S (Parametric Equivalent): This part is a parametric equivalent with identical voltage rating of 350 V and all other electrical and mechanical specifications matching the original KXG350VB22RM12X20LL. The EKXG351ELL220MK20S carries Active product status and is ROHS3 compliant. This part provides the most direct functional replacement while offering improved availability and regulatory compliance.

Both substitute parts are manufactured by Chemi-Con within the same KXG series, ensuring design consistency and performance reliability. Selection between the upgrade and equivalent substitute depends on circuit voltage requirements and design specifications.

Frequently Asked Questions (FAQ)

Q: Can the EKXG401ELL220MK20S (400 V) be used in place of the KXG350VB22RM12X20LL (350 V)?

A: Yes. The EKXG401ELL220MK20S is a valid substitute with a higher voltage rating. A capacitor with a higher voltage rating can be used in circuits designed for lower voltage operation without performance degradation. All other electrical and mechanical parameters are identical.

Q: What is the difference between the upgrade substitute and the parametric equivalent?

A: The EKXG401ELL220MK20S (upgrade) has a 400 V rating, while the EKXG351ELL220MK20S (equivalent) maintains the original 350 V rating. Both parts are electrically and mechanically identical in all other specifications. Selection depends on whether the circuit design can accommodate the higher voltage rating.

Q: Are the substitute parts physically compatible with the original PCB layout?

A: Yes. Both substitute parts maintain identical mechanical specifications: 0.197" (5.00 mm) lead spacing, 0.492" (12.50 mm) case diameter, and 0.787" (20.00 mm) seated height. Through-hole mounting configuration and radial lead orientation are identical, ensuring direct PCB compatibility.

Q: Why is the original KXG350VB22RM12X20LL marked as obsolete?

A: The KXG350VB22RM12X20LL is classified as obsolete by the manufacturer. Active substitute parts within the same KXG series are available to support ongoing production requirements and provide improved regulatory compliance.

Q: Do the substitute parts meet current RoHS requirements?

A: Yes. Both EKXG401ELL220MK20S and EKXG351ELL220MK20S are ROHS3 compliant, whereas the original KXG350VB22RM12X20LL is RoHS non-compliant. This provides improved compliance for new designs and manufacturing processes.

Q: Are the electrical performance characteristics identical between all three parts?

A: Yes, with the exception of voltage rating. Capacitance (22 µF), tolerance (±20%), lifetime (10,000 Hrs @ 105°C), operating temperature range (-40°C ~ 105°C), and ripple current specifications (260 mA @ 120 Hz and 650 mA @ 100 kHz) are identical across all three parts.
