EEU-TA1J331S Equivalent & Substitute Parts

Part Overview

The EEU-TA1J331S is a 330 µF, 63 V aluminum electrolytic capacitor in radial through-hole configuration, manufactured by Panasonic Electronic Components. This capacitor is rated for 2000 hours at 125°C and is designed for general-purpose applications. The part is currently active in production with 1102 units in stock.

Substitute parts are identified when equivalent capacitance and tolerance values are maintained while voltage ratings, ESR characteristics, or operational lifetime may be upgraded to meet enhanced system requirements or improve component availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EEU-TA1J331S is determined by the following criteria:

• Capacitance value must equal 330 µF
• Tolerance must be ±20%
• Voltage rating must be equal to or greater than 63 V
• Mounting type must be Through Hole
• Package type must be Radial, Can
• Lead spacing must be 0.295" (7.50mm)
• Physical dimensions (diameter and height) must be compatible with PCB layout constraints

The EGXF101ELL331MM20S qualifies as a substitute part because it maintains the required capacitance, tolerance, and physical form factor while providing an upgraded voltage rating of 100 V and extended operational lifetime of 3000 hours at 125°C.

Parameter Comparison

Engineering Selection Recommendations

Both the EEU-TA1J331S and EGXF101ELL331MM20S are active production parts with full regulatory compliance. The EEU-TA1J331S is suitable for applications requiring a 63 V rated capacitor with general-purpose specifications. The EGXF101ELL331MM20S provides an upgraded voltage rating of 100 V and extended lifetime of 3000 hours at 125°C, making it applicable to automotive environments where AEC-Q200 qualification is required.

Selection between these parts depends on system voltage requirements and operational lifetime expectations. The substitute part's higher voltage rating provides additional design margin in circuits operating near the 63 V threshold. The extended lifetime rating of the substitute part supports applications requiring enhanced reliability over extended operational periods.

Frequently Asked Questions (FAQ)

Q: Can the EGXF101ELL331MM20S replace the EEU-TA1J331S in any application?

A: The EGXF101ELL331MM20S is electrically and mechanically compatible with the EEU-TA1J331S. Both parts share identical capacitance (330 µF), tolerance (±20%), lead spacing (0.295"), and physical diameter (0.709"). The substitute part's 100 V rating is suitable for circuits designed for 63 V operation. Height difference is 0.020" (0.50mm), which is negligible for most PCB layouts.

Q: What are the key differences between these parts?

A: The primary differences are voltage rating (63 V vs. 100 V), operational lifetime (2000 hours vs. 3000 hours at 125°C), and manufacturer (Panasonic vs. Chemi-Con). The substitute part includes specified ESR of 69 mOhm at 100 kHz, while the main part does not provide this specification. The substitute part carries AEC-Q200 automotive qualification.

Q: Are both parts RoHS compliant?

A: Yes. The EEU-TA1J331S is ROHS3 Compliant, and the EGXF101ELL331MM20S is RoHS Compliant. Both parts are REACH Unaffected.

Q: Does the height difference affect PCB compatibility?

A: The substitute part is 0.020" (0.50mm) shorter than the main part (0.846" vs. 0.866" seated height). This difference is within typical PCB design tolerances and does not affect mechanical compatibility for through-hole mounting applications.

Q: Which part should be selected for automotive applications?

A: The EGXF101ELL331MM20S is qualified to AEC-Q200 automotive standards and is the appropriate selection for automotive circuit designs. The EEU-TA1J331S is designated for general-purpose applications.
