MVK6.3VC47RME55TP Equivalent & Substitute Parts

Part Overview

The MVK6.3VC47RME55TP is a 47 µF, 6.3 V aluminum electrolytic capacitor manufactured by Chemi-Con in surface mount radial can package. This component is classified as Obsolete, indicating discontinuation from active production. The part operates across a temperature range of -40°C to 105°C with a rated lifetime of 1000 hours at 105°C, suitable for general-purpose applications requiring stable capacitance and low equivalent series resistance.

Identification of equivalent and substitute parts is necessary due to the obsolete status of the MVK6.3VC47RME55TP. Substitute components must maintain electrical compatibility through matching capacitance, voltage rating, tolerance, and physical dimensions while accommodating variations in ESR, ripple current handling, and operating temperature ranges.

Engineering Selection Recommendations

Primary Recommendation - Direct Replacement (Same Height):

EMVY6R3ARA470ME55G (Chemi-Con MVY series) is the preferred substitute. This part maintains identical physical dimensions (5.20mm height) to the reference MVK6.3VC47RME55TP, eliminating PCB clearance concerns. The EMVY6R3ARA470ME55G is Active status with ROHS3 compliance, providing long-term supply assurance and regulatory alignment. Extended operating temperature range (-55°C to 105°C) provides additional margin for temperature-sensitive applications.

Secondary Recommendation - Extended Temperature Range:

UWT0J470MCL1GB (Nichicon UWT series) offers Active product status with extended lower temperature limit (-55°C). Height of 5.40mm requires verification of PCB clearance. This part is suitable for applications requiring broader temperature operation while maintaining identical electrical specifications.

Alternative Recommendation - Higher Ripple Current Capability:

AVEZ476M06C12T-F (Cornell Dubilier AVEZ series) provides significantly elevated ripple current capacity (88 mA @ 120Hz) compared to the reference specification (36 mA). This part is Active status with ROHS3 compliance. Height of 5.50mm requires PCB clearance verification. Selection is appropriate for applications with elevated AC ripple current stress.

Not Recommended for New Designs:

EEE-FC0J470R and EEE-HA0J470R (Panasonic FC and HA series) carry "Not For New Designs" status. While electrically compatible, these parts should not be selected for new circuit development due to discontinued design support.

Obsolete Status Consideration:

EMVE6R3ARA470ME55G (Chemi-Con MVE series) and parts with Last Time Buy status (Rubycon SKV and SZV series) are approaching or have reached end-of-life. These parts are acceptable for replacement applications but should not be selected for new designs requiring long-term supply continuity.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different height (5.40mm or 5.50mm) instead of the original 5.20mm?

A: Height variation is allowable only if PCB layout provides sufficient clearance above the component. Verify that the increased height does not interfere with adjacent components, solder bridges, or conformal coatings. Rubycon SKV and SZV series (5.50mm) and Panasonic FC/HA series (5.40mm) are mechanically compatible if clearance exists.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: RoHS Compliant indicates compliance with the original Restriction of Hazardous Substances directive. ROHS3 Compliant indicates compliance with the updated RoHS 3 directive (2015/863/EU), which includes additional restricted substances. ROHS3 Compliant parts are preferred for new designs and applications subject to current regulatory requirements.

Q: The reference part is RoHS non-compliant. Can I substitute it with a ROHS3 Compliant part?

A: Yes. ROHS3 Compliant substitutes are electrically and mechanically equivalent and provide improved regulatory alignment. This substitution is appropriate for applications where regulatory compliance is required or preferred.

Q: Does the ripple current specification affect my circuit design?

A: Ripple current rating determines the maximum AC current the capacitor can safely handle without excessive temperature rise. If your circuit requires ripple current exceeding 36 mA @ 120Hz, select a substitute with higher ripple current rating such as AVEZ476M06C12T-F (88 mA) or 6.3SZV47M5X5.5 (66.5 mA). Exceeding the rated ripple current reduces component lifetime.

Q: What is ESR and why does it vary among substitutes?

A: Equivalent Series Resistance (ESR) represents the internal resistance of the capacitor at a specified frequency. Lower ESR reduces heat generation and improves high-frequency performance. The reference part specifies 10.58 Ohm @ 120Hz. Substitutes with unspecified ESR may vary; if ESR is critical to your application, select AVES476M06C12T-F (10.6 Ohm @ 120Hz) for comparable performance.

Q: Can I use a substitute with an extended temperature range (e.g., -55°C to 105°C) in place of the original (-40°C to 105°C)?

A: Yes. Extended lower temperature limits provide additional operational margin without affecting circuit compatibility. This substitution is appropriate for applications operating in cold environments or requiring enhanced temperature margin.

Q: What packaging options are available for these substitutes?

A: The reference part is supplied in standard packaging. Substitutes are available in Tape & Reel (TR), Cut Tape (CT), and Digi-Reel formats. Verify packaging compatibility with your procurement and assembly processes. Tape & Reel is standard for automated assembly; Cut Tape is suitable for manual or small-volume assembly.

Q: Is the Chemi-Con EMVY6R3ARA470ME55G the best substitute?

A: EMVY6R3ARA470ME55G is the recommended primary substitute due to identical physical dimensions, Active product status, and ROHS3 compliance. It eliminates PCB redesign risk and provides long-term supply assurance. Selection of alternative substitutes depends on specific application requirements regarding temperature range, ripple current capacity, or regulatory compliance.
