Key Parameters

Substitute Part Grouping Explanation

Substitution of the KXG200VB331M18X35LL is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Parameters (Must Match):

• Capacitance: 330 µF
• Voltage Rating: 200 V
• Tolerance: ±20%
• Lifetime: 10,000 Hrs @ 105°C
• Operating Temperature Range: -40°C ~ 105°C
• Polarization: Polar

Mechanical Parameters (Must Match):

• Lead Spacing: 0.295" (7.50 mm)
• Case Diameter: 0.709" (18.00 mm)
• Mounting Type: Through Hole
• Package Type: Radial, Can

Substitute parts are grouped into two categories:

Parametric Equivalent (Same Manufacturer): EKXG201ELL331MMP1S from Chemi-Con maintains identical electrical specifications and mechanical dimensions. This part is active and RoHS3 compliant, providing a direct upgrade path from the obsolete KXG200VB331M18X35LL.

Direct Manufacturer Equivalent (Alternative Manufacturer): UCS2D331MHD from Nichicon meets all electrical and mechanical requirements with minor variations in ripple current specifications and maximum seated height (37.00 mm vs. 35.50 mm). This part is active and RoHS3 compliant.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Manufacturer): EKXG201ELL331MMP1S is the primary substitute for KXG200VB331M18X35LL. Both parts are manufactured by Chemi-Con and share identical electrical and mechanical specifications. EKXG201ELL331MMP1S is active in production and RoHS3 compliant, making it suitable for new designs and legacy system replacements where manufacturer continuity is preferred.

For Cross-Manufacturer Substitution: UCS2D331MHD from Nichicon is a qualified alternative when Chemi-Con parts are unavailable. This Nichicon part meets all core electrical requirements and maintains compatible mechanical dimensions for through-hole PCB mounting. The maximum seated height of UCS2D331MHD is 1.457" (37.00 mm) compared to 1.398" (35.50 mm) for the original part; verify clearance in space-constrained applications. UCS2D331MHD is active and RoHS3 compliant.

Compliance Considerations: Both substitute parts are RoHS3 compliant, whereas the original KXG200VB331M18X35LL is non-compliant. For applications subject to RoHS regulations, substitution with either EKXG201ELL331MMP1S or UCS2D331MHD is required.

Frequently Asked Questions (FAQ)

Q: Can EKXG201ELL331MMP1S be used as a direct drop-in replacement for KXG200VB331M18X35LL?

A: Yes. EKXG201ELL331MMP1S is electrically and mechanically identical to KXG200VB331M18X35LL. Both parts have 330 µF capacitance, 200 V rating, identical lead spacing (7.50 mm), case diameter (18.00 mm), and maximum seated height (35.50 mm). No PCB modifications are required.

Q: What is the difference between EKXG201ELL331MMP1S and UCS2D331MHD?

A: Both parts meet the electrical specifications of the original KXG200VB331M18X35LL. The primary differences are: (1) Manufacturer—EKXG201ELL331MMP1S is Chemi-Con; UCS2D331MHD is Nichicon; (2) Maximum seated height—EKXG201ELL331MMP1S is 35.50 mm; UCS2D331MHD is 37.00 mm; (3) Ripple current at 120 Hz—EKXG201ELL331MMP1S is 1.43 A; UCS2D331MHD is 1.61 A. All other parameters are equivalent.

Q: Will the increased height of UCS2D331MHD (37.00 mm vs. 35.50 mm) cause PCB assembly issues?

A: The height difference is 1.50 mm. Verify available clearance above the component location on the PCB. If the design has tight vertical constraints, EKXG201ELL331MMP1S is preferred due to its lower profile matching the original part exactly.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both EKXG201ELL331MMP1S and UCS2D331MHD are RoHS3 compliant. The original KXG200VB331M18X35LL is RoHS non-compliant. Substitution with either part satisfies RoHS regulatory requirements.

Q: Can I use these substitutes in high-ripple-current applications?

A: Both substitute parts are rated for ripple current handling equivalent to or exceeding the original part. EKXG201ELL331MMP1S matches the original ripple current specifications exactly (1.43 A @ 120 Hz; 3.2175 A @ 100 kHz). UCS2D331MHD provides slightly higher ripple current capability (1.61 A @ 120 Hz; 3.22 A @ 100 kHz). Both are suitable for general-purpose power supply and filtering applications.

Q: What is the lead spacing for all three parts?

A: All three parts—KXG200VB331M18X35LL, EKXG201ELL331MMP1S, and UCS2D331MHD—have identical lead spacing of 0.295" (7.50 mm), ensuring compatibility with existing PCB footprints.

Q: Is inventory availability a factor in selecting a substitute?

A: Inventory levels are subject to change. EKXG201ELL331MMP1S (805 Pcs) and UCS2D331MHD (4,350 Pcs) are both in stock. Verify current availability with your supplier before finalizing component selection.
