EEE-FPJ470UAR Equivalent & Substitute Parts

Part Overview

The EEE-FPJ470UAR is a 47 µF, 6.3 V aluminum electrolytic capacitor in surface mount radial can package manufactured by Panasonic Electronic Components. This part is classified as Active and meets AEC-Q200 automotive qualification standards. The component is designed for automotive applications requiring reliable energy storage and filtering in circuits operating at 6.3 V nominal voltage.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design requirements necessitate upgraded electrical performance characteristics such as higher voltage ratings or improved ESR specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the EEE-FPJ470UAR is determined by the following criteria:

Direct Substitutes maintain identical electrical specifications: 47 µF capacitance, 6.3 V voltage rating, ±20% tolerance, 2000 Hrs @ 105°C lifetime, and identical physical package dimensions (0.157" diameter, 0.228" height, 4.30 mm x 4.30 mm land size). These parts are interchangeable without circuit redesign.

Upgrade Substitutes increase the voltage rating from 6.3 V to 16 V while maintaining 47 µF capacitance, ±20% tolerance, and 2000 Hrs @ 105°C lifetime. These parts occupy identical or compatible physical footprints and provide enhanced voltage margin. Upgrade substitutes are suitable for circuits where higher voltage headroom is beneficial or required.

Similar Substitutes maintain the same capacitance and voltage rating but differ in physical dimensions or ESR characteristics. These parts require PCB layout verification to confirm mechanical compatibility.

Cross-Manufacturer Substitutes from alternative manufacturers (Rubycon) meet identical electrical and mechanical specifications, AEC-Q200 automotive qualification, and RoHS3 compliance.

Engineering Selection Recommendations

For Direct Replacement (No Circuit Modification Required): EEE-FKJ470UAR and 6.3TZV47M4X6.1 are direct electrical equivalents. Both maintain 47 µF capacitance, 6.3 V voltage rating, and 2000 Hrs @ 105°C lifetime. EEE-FKJ470UAR is a Panasonic part with Active product status. The Rubycon 6.3TZV47M4X6.1 provides cross-manufacturer equivalence with identical AEC-Q200 and RoHS3 compliance. Height difference (0.240" vs. 0.228") requires PCB layout verification for mechanical clearance.

For Voltage Margin Enhancement: EEE-FT1C470AR provides an upgrade path with 16 V rating while maintaining 47 µF capacitance, 850 mOhm ESR, and Active product status. This part is suitable for applications requiring higher voltage headroom. Physical footprint compatibility is confirmed (identical land size and case diameter). EEE-FK1C470SR offers similar voltage upgrade but carries "Not For New Designs" status and should be avoided for new product development.

For ESR Optimization: EEE-FP0J470AR features reduced ESR (360 mOhm vs. 850 mOhm) at the cost of increased physical dimensions (0.197" diameter, 5.30 mm x 5.30 mm land size). This part is suitable only if PCB layout accommodates the larger footprint and lower ESR is a circuit requirement.

Compliance Verification: All substitute parts maintain AEC-Q200 automotive qualification, RoHS3 compliance, and Moisture Sensitivity Level 1 (Unlimited). Selection should prioritize Active product status parts for new designs.

Frequently Asked Questions (FAQ)

Q: Can EEE-FKJ470UAR replace EEE-FPJ470UAR directly on the PCB? A: Yes, electrically. Both parts are 47 µF, 6.3 V, ±20% tolerance with identical land size (4.30 mm x 4.30 mm). However, EEE-FKJ470UAR is 0.012" (0.30 mm) taller (0.240" vs. 0.228"). Verify PCB clearance above the component before substitution.

Q: What is the advantage of using EEE-FT1C470AR instead of the original part? A: EEE-FT1C470AR increases voltage rating to 16 V, providing additional voltage margin in the circuit. It maintains identical ESR (850 mOhm), capacitance (47 µF), and footprint compatibility. This upgrade is suitable for circuits where higher voltage headroom improves reliability or design flexibility.

Q: Is the Rubycon 6.3TZV47M4X6.1 suitable for automotive applications? A: Yes. The Rubycon part meets AEC-Q200 automotive qualification, RoHS3 compliance, and identical electrical specifications (47 µF, 6.3 V, 2000 Hrs @ 105°C). Cross-manufacturer substitution is valid for automotive use.

Q: Why is EEE-FK1C470SR marked "Not For New Designs"? A: Parts with this status are in mature or declining production phases. While electrically functional, Panasonic recommends EEE-FT1C470AR as the preferred 16 V upgrade alternative for new product development.

Q: Can EEE-FP0J470AR be used as a drop-in replacement? A: No. While electrically equivalent (47 µF, 6.3 V), EEE-FP0J470AR has a larger physical footprint (0.197" diameter, 5.30 mm x 5.30 mm land size vs. 4.00 mm diameter, 4.30 mm x 4.30 mm land size). PCB redesign is required for mechanical compatibility.

Q: What does ESR specification mean for capacitor selection? A: ESR (Equivalent Series Resistance) affects ripple current handling and heat dissipation. Lower ESR (360 mOhm in EEE-FP0J470AR) reduces heat generation under AC ripple current. Higher ESR (850 mOhm in EEE-FPJ470UAR) is acceptable for lower ripple current applications. Selection depends on circuit ripple current requirements.
