KMG63VB47RM6X11LL Equivalent & Substitute Parts

Part Overview

The KMG63VB47RM6X11LL is a 47 µF, 63 V aluminum electrolytic capacitor in radial, can package manufactured by Chemi-Con. This component is classified as obsolete product status. The part operates across a temperature range of -55°C to 105°C with a rated lifetime of 1000 hours at 105°C, suitable for general-purpose applications requiring stable capacitance and ripple current handling.

Due to obsolete product status, equivalent substitute parts from active product lines are necessary to ensure continued component availability and supply chain reliability for new designs and production runs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KMG63VB47RM6X11LL is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 47 µF
• Voltage Rating: 63 V
• Tolerance: ±20%
• Polarization: Polar
• Mounting Type: Through Hole
• Package Type: Radial, Can
• Lead Spacing: 0.098" (2.50mm)
• Size / Dimension: 0.248" Dia (6.30mm)
• Operating Temperature Range: -55°C ~ 105°C
• Lifetime @ Temperature: 1000 Hrs @ 105°C
• Ripple Current @ Low Frequency: 120 mA @ 120 Hz

All substitute parts listed meet these mandatory parameters. Variations in height, ESR specifications, and ripple current at high frequency do not disqualify substitution when all primary electrical and mechanical parameters align.

Engineering Selection Recommendations

Primary Recommendation: EKMG630ELL470MF11D

EKMG630ELL470MF11D is the preferred substitute. Manufactured by Chemi-Con, it maintains the same series lineage (KMG) as the original part. This part carries active product status and ROHS3 compliance certification. The increased height of 0.492" (12.50mm) versus the original 0.433" (11.00mm) requires PCB layout verification. Higher ripple current capability at 100 kHz (216 mA) provides enhanced performance margin. Bulk packaging is available with 9100 units in stock.

Secondary Recommendation: ECA-1JHG470

ECA-1JHG470 from Panasonic Electronic Components is an active product with ROHS3 compliance. Height of 0.480" (12.20mm) represents a minimal increase from the original specification. Ripple current at 100 kHz matches the original part at 180 mA. This part offers the largest inventory availability at 15093 units in stock, supporting extended production requirements.

Alternative Option: UVZ1J470MED

UVZ1J470MED from Nichicon meets all mandatory electrical and mechanical parameters. Although classified as obsolete, it carries ROHS3 compliance. Ripple current capability at 10 kHz reaches 240 mA. This part is suitable only when active product alternatives are unavailable and existing inventory is confirmed.

Frequently Asked Questions (FAQ)

Q: Can EKMG630ELL470MF11D be used as a direct replacement for KMG63VB47RM6X11LL?

A: Yes. Both parts share identical electrical specifications: 47 µF capacitance, 63 V rating, ±20% tolerance, and 1000 hour lifetime at 105°C. The primary difference is height: 0.492" (12.50mm) versus 0.433" (11.00mm). PCB layout must accommodate the increased height. Lead spacing and diameter remain identical at 0.098" (2.50mm) and 0.248" (6.30mm) respectively.

Q: What is the significance of the height difference between substitute parts?

A: Height variation ranges from 0.433" (11.00mm) for the original to 0.492" (12.50mm) for EKMG630ELL470MF11D and UVZ1J470MED. ECA-1JHG470 measures 0.480" (12.20mm). These differences affect PCB clearance, component stacking, and enclosure fit. Design verification is required before implementation.

Q: Are all substitute parts RoHS compliant?

A: EKMG630ELL470MF11D and ECA-1JHG470 carry ROHS3 compliance certification. UVZ1J470MED also meets ROHS3 standards. The original KMG63VB47RM6X11LL is RoHS non-compliant. Compliance requirements for your application determine which substitute is appropriate.

Q: What is the difference between ripple current specifications at different frequencies?

A: Ripple current capacity varies by frequency. All substitute parts maintain 120 mA at 120 Hz, matching the original specification. At higher frequencies: EKMG630ELL470MF11D provides 216 mA @ 100 kHz, ECA-1JHG470 provides 180 mA @ 100 kHz, and UVZ1J470MED provides 240 mA @ 10 kHz. Higher ripple current capability indicates better performance under AC stress conditions.

Q: Which substitute offers the best long-term availability?

A: ECA-1JHG470 from Panasonic Electronic Components is recommended for long-term availability. It carries active product status with 15093 units currently in stock. EKMG630ELL470MF11D also maintains active status with 9100 units available. Both manufacturers support ongoing production and supply chain continuity.

Q: Can UVZ1J470MED be used despite its obsolete status?

A: UVZ1J470MED meets all mandatory electrical and mechanical parameters and carries ROHS3 compliance. However, obsolete product status indicates discontinued manufacturing. This part is suitable only when active alternatives are unavailable and existing inventory is confirmed for your production timeline.

Q: Are there any thermal performance differences between substitute parts?

A: All parts share identical thermal specifications: -55°C to 105°C operating range and 1000 hour lifetime at 105°C. ESR (Equivalent Series Resistance) data is not provided for substitute parts, preventing direct thermal performance comparison. Thermal behavior under specific ripple current conditions may vary due to different ESR values.
