EEU-FS1J331L Equivalent & Substitute Parts

Part Overview

The EEU-FS1J331L is a 330 µF, 63 V aluminum electrolytic capacitor in radial configuration manufactured by Panasonic Electronic Components. This through-hole component is rated for 10,000 hours at 105°C and is designed for general-purpose applications requiring stable capacitance and ripple current handling. The part maintains Active product status with full RoHS3 compliance. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Substitute Part Grouping Explanation

Substitution eligibility for the EEU-FS1J331L is determined by strict equivalence across the following parameters: capacitance value (330 µF), voltage rating (63 V), tolerance (±20%), polarization (Polar), mounting type (Through Hole), and package configuration (Radial, Can). The substitute part must maintain identical lead spacing (5.00 mm) and case diameter (10.00 mm) to ensure mechanical compatibility with existing PCB layouts. Lifetime rating of 10,000 hours at 105°C and operating temperature range of -40°C to 105°C are required specifications. RoHS3 compliance and equivalent regulatory status (REACH Unaffected, EAR99 classification) are mandatory for direct substitution in compliant applications.

The Rubycon 63ZLH330MEFC10X23 meets all substitution criteria through identical electrical ratings, mechanical dimensions, thermal specifications, and regulatory compliance.

Engineering Selection Recommendations

Both the EEU-FS1J331L and 63ZLH330MEFC10X23 maintain Active product status and full regulatory compliance (RoHS3, REACH Unaffected, EAR99). The Rubycon substitute provides equivalent electrical performance with identical capacitance, voltage rating, tolerance, and thermal specifications. The seated height difference of 0.5 mm (25.50 mm vs. 25.00 mm) is within typical PCB clearance tolerances for through-hole radial capacitors and does not affect functional compatibility. Selection between these parts may be based on inventory availability, supply chain logistics, or design flexibility requirements, as both components satisfy the specified electrical and mechanical requirements.

Frequently Asked Questions (FAQ)

Q: Can the Rubycon 63ZLH330MEFC10X23 be used as a direct replacement for the Panasonic EEU-FS1J331L?

A: Yes. Both components share identical capacitance (330 µF), voltage rating (63 V), tolerance (±20%), lead spacing (5.00 mm), case diameter (10.00 mm), and thermal specifications (10,000 Hrs @ 105°C). Mechanical compatibility is confirmed through matching through-hole mounting configuration and radial can package type.

Q: What is the significance of the 0.5 mm height difference?

A: The Panasonic part measures 25.50 mm seated height while the Rubycon part measures 25.00 mm. This difference is negligible for through-hole PCB applications and does not impact electrical performance or mechanical fit within standard component clearance specifications.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the EEU-FS1J331L and 63ZLH330MEFC10X23 are RoHS3 compliant, REACH Unaffected, and classified as EAR99 for export control purposes.

Q: What parameters must remain constant for substitution eligibility?

A: Capacitance value, voltage rating, tolerance, polarization, lead spacing, case diameter, mounting type, package configuration, and thermal lifetime rating must be identical. Operating temperature range and regulatory compliance status must also match.

Q: Can these parts be used interchangeably in production?

A: Yes, provided the PCB layout accommodates the maximum seated height of 25.50 mm. Both components are rated for identical electrical and thermal performance in general-purpose applications.
