The Panasonic EEU-TA1J471S is a through-hole aluminum electrolytic capacitor engineered for general-purpose applications requiring stable bulk energy storage and ripple current handling in moderate-temperature environments. With a capacitance of 470 µF at 63 V DC working voltage and ±20% tolerance, this component serves filtering, decoupling, and power supply smoothing functions across industrial controls, consumer electronics, and power conversion circuits.
This radial leaded capacitor measures 0.709 inches (18.00mm) in diameter with a maximum seated height of 1.063 inches (27.00mm), utilizing a 0.295-inch (7.50mm) lead spacing configuration compatible with standard PCB through-hole mounting. The cylindrical can package facilitates manual assembly and automated insertion processes while maintaining mechanical stability under vibration and thermal cycling conditions typical of industrial equipment.
The TA series construction provides an operational temperature range from -40°C to 125°C with a rated lifetime of 2000 hours at maximum temperature, reflecting the component's aluminum electrolyte chemistry and internal construction. Ripple current capability reaches 1.493 A at 120 Hz and extends to 1.99 A at 100 kHz, addressing both line-frequency and switching-frequency noise suppression requirements in power electronics. The 60 milliohm impedance at rated frequency contributes to effective voltage stabilization in supply rails carrying dynamic loads.
As a polar component, the EEU-TA1J471S requires correct polarity orientation during installation. The general-purpose classification indicates suitability for commercial-grade equipment where cost-effectiveness and reliability balance against specialized high-performance requirements. The radial through-hole format provides serviceable connections in prototypes, field-replaceable assemblies, and designs prioritizing ease of inspection over board space optimization.
Compliance with RoHS3 directives and REACH unaffected status confirms material composition meets current environmental regulations for mainstream manufacturing and international distribution. The bulk packaging format supports volume production while the active product status ensures ongoing availability for new designs and maintenance stock. This 63V 470µF aluminum electrolytic capacitor addresses standard voltage rails in 48V telecom power systems, motor drive DC buses, and audio amplifier supply filtering where the 2000-hour endurance specification aligns with typical service intervals and replacement cycles.

A valid EEU-TA1J471S replacement is not determined by capacitance and voltage alone. The most relevant checks are ripple current capability, operating temperature rating, impedance or ESR behavior, can diameter, height, lead spacing, polarity, lifetime rating, and the thermal environment around the capacitor. A part that fits the PCB footprint may still be unsuitable if its ripple current rating or temperature endurance is lower than required.
What the Panasonic EEU-TA1J471S TA Series Capacitor Defines for Replacement Selection
| Parameter | Panasonic EEU-TA1J471S Value | Replacement Impact |
|---|---|---|
| Manufacturer | Panasonic Electronic Components | Same-brand alternatives may reduce qualification effort |
| Series | TA | Establishes the original temperature and endurance class |
| Capacitance | 470 µF | Replacement should normally match 470 µF unless circuit tolerance allows adjustment |
| Capacitance tolerance | ±20% | Common for aluminum electrolytic capacitors; most alternatives match this |
| Rated voltage | 63 VDC | Replacement voltage should be 63 V or higher, subject to size and ripple trade-offs |
| Operating temperature | -40°C to +125°C | Lower-temperature alternatives require thermal derating review |
| Lifetime | 2000 hours at 125°C | Must be compared using actual capacitor core temperature, not only ambient temperature |
| Ripple current | 1.493 A at 120 Hz; 1.99 A at 100 kHz | Replacement must handle application ripple frequency and RMS ripple current |
| Impedance | 60 mΩ | Useful benchmark for power supply filtering and ripple heating |
| Mounting type | Through-hole | SMD capacitors are not drop-in replacements without PCB changes |
| Package | Radial can | Replacement must match PCB layout and clearance envelope |
| Diameter | 18.00 mm | Affects mechanical fit, airflow, and spacing to nearby parts |
| Height | 27.00 mm max | Taller parts may conflict with enclosure or heat sinks |
| Lead spacing | 7.50 mm | One of the main drop-in compatibility checks |
| Polarity | Polar | Incorrect polarity substitution is not acceptable |
| Compliance | RoHS3 compliant, REACH unaffected | Relevant for production and regional compliance |
The Panasonic EEU-TA1J471S is generally used where high ripple handling, elevated temperature capability, and through-hole mechanical robustness are needed. Typical applications include AC-DC power supplies, DC bus filtering, industrial controls, motor-drive auxiliary rails, lighting power modules, and general-purpose energy storage where the capacitor may be exposed to warm operating conditions.
For replacement work, the 125°C rating is a major differentiator. A 105°C capacitor can sometimes replace the EEU-TA1J471S if the measured operating temperature is moderate and the calculated lifetime remains acceptable. However, in compact power supplies, sealed enclosures, automotive-adjacent equipment, or high-ripple rails, another 125°C part is usually the safer engineering direction.
