KXG200VB47RM12X20LL Equivalent & Substitute Parts

Part Overview

The KXG200VB47RM12X20LL is a 47 µF, 200 V aluminum electrolytic capacitor in radial, can package manufactured by Chemi-Con. This component is classified as obsolete, indicating discontinued production and limited availability. The part operates across a temperature range of -40°C to 105°C with a rated lifetime of 10,000 hours at 105°C, suitable for general-purpose applications requiring stable capacitance and ripple current handling.

Due to obsolete status and limited inventory (1,048 pieces), identifying equivalent and substitute parts is necessary for design continuity, procurement reliability, and long-term product support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of aluminum electrolytic capacitors is determined by strict equivalence in the following parameters:

Critical Parameters (Must Match):

• Capacitance: 47 µF
• Tolerance: ±20%
• Operating Temperature Range: -40°C to 105°C
• Lifetime @ 105°C: 10,000 hours
• Mounting Type: Through Hole
• Package / Case: Radial, Can
• Lead Spacing: 5.00 mm
• Physical Dimensions: 12.50 mm diameter, 20.00 mm height
• Polarization: Polar

Voltage Rating Consideration: Substitute parts may have equal or higher voltage ratings than the original 200 V specification. A higher voltage rating maintains backward compatibility while providing additional design margin.

Compliance Consideration: RoHS status and REACH compliance are documented for each part but do not prevent substitution; they indicate manufacturing compliance standards.

Two substitute parts are identified:

1. EKXG251ELL470MK20S (Upgrade): Identical electrical and mechanical parameters with 250 V rating (higher voltage margin) and active product status with ROHS3 compliance.

2. EKXG201ELL470MK20S (Parametric Equivalent): Identical electrical and mechanical parameters with matching 200 V rating and ROHS3 compliance, though also obsolete.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: EKXG251ELL470MK20S

This part is the preferred substitute based on the following factors:

• Product Status: Active production status ensures long-term availability and supply chain continuity.
• Compliance: ROHS3 compliant, meeting current environmental and manufacturing standards.
• Voltage Rating: 250 V rating provides additional design margin above the original 200 V specification while maintaining full backward compatibility.
• Inventory: Significantly higher stock level (68,374 pieces) compared to the original part, reducing procurement risk.
• Electrical Equivalence: All critical electrical parameters (capacitance, tolerance, ripple current, lifetime, temperature range) are identical to the original part.
• Mechanical Compatibility: Identical physical dimensions and lead spacing ensure direct PCB mounting compatibility without layout modifications.

Secondary Recommendation: EKXG201ELL470MK20S

This part provides parametric equivalence with matching 200 V voltage rating:

• Electrical Match: Identical voltage rating to the original part.
• Compliance: ROHS3 compliant.
• Limitation: Obsolete product status limits long-term availability.

Selection Criteria Summary:

For new designs or long-term production: Use EKXG251ELL470MK20S.

For applications requiring exact voltage matching with existing inventory: Use EKXG201ELL470MK20S as interim solution.

Frequently Asked Questions (FAQ)

Q1: Can EKXG251ELL470MK20S be used as a direct replacement for KXG200VB47RM12X20LL?

A: Yes. The 250 V rated EKXG251ELL470MK20S is a direct substitute. All electrical parameters (capacitance, tolerance, ripple current, lifetime, temperature range) are identical. The higher voltage rating (250 V vs. 200 V) provides additional design margin and is fully backward compatible in applications designed for 200 V operation.

Q2: What is the difference between the two substitute parts?

A: Both EKXG251ELL470MK20S and EKXG201ELL470MK20S are electrically and mechanically identical to the original part. The primary difference is voltage rating: EKXG251ELL470MK20S is rated 250 V (upgrade), while EKXG201ELL470MK20S is rated 200 V (parametric equivalent). EKXG251ELL470MK20S has active product status and higher inventory availability.

Q3: Are there any PCB layout changes required when substituting these parts?

A: No. All substitute parts have identical lead spacing (5.00 mm), diameter (12.50 mm), and height (20.00 mm). Direct PCB mounting compatibility is maintained without layout modifications.

Q4: Why is the original part obsolete?

A: The KXG200VB47RM12X20LL is classified as obsolete, indicating discontinued production by Chemi-Con. Substitute parts from the same KXG series with active production status are available.

Q5: Does the higher voltage rating of EKXG251ELL470MK20S affect circuit performance?

A: No. In capacitor applications, a higher voltage rating does not alter capacitance, ripple current handling, or frequency response. The higher rating only increases the voltage stress margin, providing additional safety in the circuit.

Q6: Are the substitute parts RoHS compliant?

A: Yes. Both EKXG251ELL470MK20S and EKXG201ELL470MK20S are ROHS3 compliant. The original KXG200VB47RM12X20LL is RoHS non-compliant, reflecting its obsolete status and earlier manufacturing date.

Q7: What is the lead spacing specification, and why is it important?

A: Lead spacing is 5.00 mm (0.197 inches) for all three parts. This specification determines PCB hole pitch and is critical for ensuring mechanical fit without modification to existing circuit board designs.

Q8: Can these parts be used in high-frequency applications?

A: Yes. All parts support ripple current of 975 mA at 100 kHz, indicating suitability for high-frequency switching applications within the specified current limits.
