6SEPC470MX Equivalent & Substitute Parts

Part Overview

The 6SEPC470MX is a 470 µF, 6.3 V aluminum polymer capacitor manufactured by Panasonic Electronic Components in the OS-CON™ SEPC series. This through-hole radial can capacitor is designed for general-purpose applications requiring low equivalent series resistance and extended operational life. The part is currently active in production with 3,702 units in stock. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to component availability, supply chain considerations, or design flexibility within the same performance envelope.

Engineering Selection Recommendations

Both the 6SEPC470MX and RL80J471MDNASQ are active production components with full regulatory compliance. Selection between these parts should be based on:

• Availability: The 6SEPC470MX has 3,702 units in stock; the RL80J471MDNASQ has 937 units in stock
• Ripple Current Performance: The RL80J471MDNASQ provides higher ripple current capability at low frequency (570 mA @ 120 Hz versus 285 mA @ 120 Hz), while both deliver identical performance at high frequency (5.7 A @ 100 kHz)
• Regulatory Compliance: Both parts meet ROHS3 and REACH requirements, ensuring compatibility with current environmental standards
• Mechanical Compatibility: Identical footprint, lead spacing, and case dimensions ensure direct board-level substitution without layout modifications

Frequently Asked Questions (FAQ)

Q: Can the RL80J471MDNASQ directly replace the 6SEPC470MX in existing designs?

A: Yes. Both parts share identical electrical ratings (470 µF, 6.3 V, 8 mOhm ESR, 5000 Hrs @ 105°C), operating temperature range (-55°C to 105°C), and mechanical specifications (through-hole radial can, 0.138" lead spacing, 0.315" diameter, 0.354" height). Direct substitution is supported at the board level without design modifications.

Q: What is the difference in ripple current capability?

A: At low frequency (120 Hz), the RL80J471MDNASQ is rated for 570 mA compared to the 6SEPC470MX at 285 mA. At high frequency (100 kHz), both parts are rated identically at 5.7 A. Selection should consider the specific ripple current requirements of the application.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the 6SEPC470MX and RL80J471MDNASQ are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the tolerance specification for these capacitors?

A: Both parts maintain a tolerance of ±20%, meaning the actual capacitance value will fall within the range of 376 µF to 564 µF at rated conditions.

Q: Are these parts suitable for high-temperature applications?

A: Yes. Both parts are rated for operation up to 105°C and maintain a 5000-hour lifetime at this temperature, making them suitable for applications requiring extended thermal performance.
