16SEPC470M Equivalent & Substitute Parts

Part Overview

The 16SEPC470M is a 470 µF, 16 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 ROHS3 compliance and REACH unaffected status. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory constraints, supply chain considerations, or application-specific performance needs.

Engineering Selection Recommendations

Both the 16SEPC470M and PLS1C471MDO1 are active production parts with identical ROHS3 compliance and REACH unaffected status. Selection between these parts is determined by availability and application-specific requirements. The PLS1C471MDO1 offers a marginal ESR advantage (9 mOhm versus 10 mOhm), which may provide improved performance in ripple current-sensitive applications. Both parts satisfy general-purpose capacitor requirements with equivalent mechanical fit and thermal performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the PLS1C471MDO1 be used as a direct replacement for the 16SEPC470M?

A: Yes. Both parts share identical capacitance (470 µF), voltage rating (16 V), tolerance (±20%), lifetime (5000 Hrs @ 105°C), operating temperature range (-55°C ~ 105°C), and mechanical dimensions (lead spacing, case diameter, height). Through-hole radial can packaging is identical.

Q: What is the difference in ESR between these parts?

A: The 16SEPC470M has an ESR of 10 mOhm, while the PLS1C471MDO1 has an ESR of 9 mOhm. This 1 mOhm difference is negligible for general-purpose applications.

Q: Are both parts compliant with environmental regulations?

A: Yes. Both the 16SEPC470M and PLS1C471MDO1 are ROHS3 compliant and REACH unaffected.

Q: Do these parts have identical physical dimensions?

A: Yes. Both parts have a 0.394" (10.00 mm) case diameter, 0.512" (13.00 mm) seated height, and 0.197" (5.00 mm) lead spacing. They are mechanically interchangeable in through-hole PCB applications.

Q: What applications are these capacitors suitable for?

A: Both parts are rated for general-purpose applications. The aluminum polymer construction and low ESR make them suitable for applications requiring stable capacitance over extended operational life at elevated temperatures.
