Substitute Part Grouping Explanation

Substitution of the KXG400VB47RM16X25LL is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Parameters:

• Capacitance: 47 µF (exact match required)
• Voltage Rating: 400 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime: 10,000 Hrs @ 105°C (exact match required)
• Operating Temperature Range: -40°C ~ 105°C (exact match required)
• Ripple Current @ 120 Hz: 470 mA (exact match required)
• Ripple Current @ 100 kHz: 1.175 A (exact match required)

Mechanical Parameters:

• Lead Spacing: 0.295" (7.50 mm) (exact match required)
• Diameter: 0.630" (16.00 mm) (exact match required)
• Height: 0.984" (25.00 mm) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package: Radial, Can (exact match required)

Substitute parts must satisfy all parameters listed above to ensure functional and physical compatibility with the original design.

Parameter Comparison

Engineering Selection Recommendations

The EKXG401ELL470ML25S is a direct parametric equivalent to the KXG400VB47RM16X25LL across all electrical and mechanical specifications. Both components are manufactured by Chemi-Con within the KXG series and share identical capacitance, voltage rating, tolerance, thermal lifetime, operating temperature range, ripple current ratings, and physical dimensions.

The primary distinction between these parts is product status and compliance certification. The KXG400VB47RM16X25LL is obsolete and RoHS non-compliant, while the EKXG401ELL470ML25S is an active product with ROHS3 compliance. For new designs and production applications, the EKXG401ELL470ML25S is the appropriate selection. For legacy system repairs where RoHS compliance is not a requirement, the EKXG401ELL470ML25S remains functionally equivalent and provides superior component availability.

Frequently Asked Questions (FAQ)

Q: Can EKXG401ELL470ML25S be used as a direct replacement for KXG400VB47RM16X25LL?

A: Yes. The EKXG401ELL470ML25S is a direct parametric equivalent. All electrical parameters (capacitance, voltage rating, tolerance, thermal lifetime, operating temperature, ripple current) and mechanical parameters (lead spacing, diameter, height, mounting type, package) are identical. Physical and functional compatibility is confirmed.

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

A: The primary differences are product status and regulatory compliance. The KXG400VB47RM16X25LL is obsolete and RoHS non-compliant. The EKXG401ELL470ML25S is an active product with ROHS3 compliance. All technical specifications are equivalent.

Q: Are there any packaging differences?

A: Both components use radial, can package with through-hole mounting. Physical dimensions are identical: 0.630" diameter (16.00 mm), 0.984" height (25.00 mm), and 0.295" lead spacing (7.50 mm). The EKXG401ELL470ML25S is supplied in bulk packaging, while the original part number does not specify packaging type in the available data.

Q: Will the EKXG401ELL470ML25S work in circuits designed for the KXG400VB47RM16X25LL?

A: Yes. Identical electrical specifications (47 µF, 400 V, ±20% tolerance, 10,000 Hrs @ 105°C) and mechanical compatibility ensure functional equivalence in all applications where the original part was specified.

Q: Is RoHS3 compliance important for my application?

A: RoHS3 compliance is required for products sold in the European Union and many other regulated markets. If your application or end-market requires RoHS compliance, the EKXG401ELL470ML25S is the appropriate selection. For legacy systems or non-regulated applications, both parts are functionally equivalent.
