EEE-TP1C331AP Equivalent & Substitute Parts

Part Overview

The EEE-TP1C331AP is a 330 µF, 16 V aluminum electrolytic capacitor in surface mount radial can package manufactured by Panasonic Electronic Components. This component is rated for automotive applications and high temperature reflow processes with a 3000-hour lifetime at 125°C. The part is Active status and ROHS3 compliant with AEC-Q200 automotive qualification.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the allowed parameter tolerances for this product category. Alternatives may be required due to inventory availability, voltage rating upgrades for design margin, or series-level improvements in electrical characteristics.

Substitutes are grouped by voltage rating upgrade (16 V to 25 V) and manufacturer series variation while maintaining all mechanical and compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

EEE-TP1E331AP (Panasonic TP Series, 25 V)

Direct upgrade within the same manufacturer series. Maintains AEC-Q200 automotive qualification and Active product status. Voltage rating increase from 16 V to 25 V provides design margin without changing mechanical footprint or electrical performance envelope. Identical ripple current ratings and lifetime specifications. Recommended for new designs requiring automotive-grade reliability.

EEE-TK1C331UP (Panasonic TK Series, 16 V)

Same voltage rating and capacitance as the main part. Panasonic series variant with specified ESR of 200mOhm @ 100kHz. Ripple current ratings are lower than the main part (175.5 mA @ 120 Hz vs. 325 mA). Active product status. Does not carry AEC-Q200 automotive qualification; rated for general purpose applications. Suitable for non-automotive designs where ripple current requirements are within specification.

25THV330M10X10.5 (Rubycon THV Series, 25 V)

Voltage upgrade to 25 V with AEC-Q200 automotive qualification. Rubycon manufacturer alternative. Height dimension is 0.413" (10.50mm), which exceeds the main part's 0.402" (10.20mm) maximum by 0.011". Mechanical compatibility must be verified for height-constrained applications. Ripple current ratings match the main part at 500 mA @ 100 kHz. Active product status.

UCZ1E331MCL1GS (Nichicon UCZ Series, 25 V)

Voltage upgrade to 25 V. Nichicon manufacturer alternative. Lowest ESR specification at 150mOhm. Height dimension is 0.394" (10.00mm), which is within specification. Product status is Not For New Designs; this part is suitable only for legacy system maintenance or replacement applications. Ripple current ratings match the main part at 500 mA @ 100 kHz.

Frequently Asked Questions (FAQ)

Q: Can EEE-TP1E331AP be used as a direct replacement for EEE-TP1C331AP?

A: Yes. Both parts are Panasonic TP series with identical capacitance (330 µF), tolerance (±20%), mechanical dimensions, and lifetime specifications (3000 Hrs @ 125°C). The EEE-TP1E331AP has a higher voltage rating (25 V vs. 16 V), which is compatible with 16 V circuit designs and provides additional design margin. Both carry AEC-Q200 automotive qualification and Active product status.

Q: What is the difference between the Panasonic TP and TK series?

A: Both series maintain the same 330 µF capacitance, ±20% tolerance, and 3000-hour lifetime at 125°C. The TK series (EEE-TK1C331UP) specifies ESR at 200mOhm @ 100kHz and has lower ripple current ratings (175.5 mA @ 120 Hz vs. 325 mA for TP series). The TP series carries AEC-Q200 automotive qualification; the TK series is rated for general purpose applications.

Q: Can I use the Rubycon 25THV330M10X10.5 in a height-constrained PCB layout?

A: The Rubycon part has a maximum seated height of 0.413" (10.50mm), which is 0.011" taller than the EEE-TP1C331AP specification of 0.402" (10.20mm). Mechanical compatibility must be verified for applications with height restrictions. The Nichicon UCZ1E331MCL1GS at 0.394" (10.00mm) is the most compact option.

Q: Why is the Nichicon UCZ1E331MCL1GS marked as Not For New Designs?

A: The UCZ1E331MCL1GS carries a Not For New Designs product status, indicating that Nichicon has discontinued this series for new applications. This part is suitable only for replacement or maintenance of existing systems. For new designs, select from Active status alternatives: EEE-TP1E331AP, EEE-TK1C331UP, or 25THV330M10X10.5.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (EEE-TP1E331AP, EEE-TK1C331UP, 25THV330M10X10.5, and UCZ1E331MCL1GS) are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the main part's compliance profile.

Q: Which substitute part has the lowest ESR?

A: The Nichicon UCZ1E331MCL1GS specifies the lowest ESR at 150mOhm. The Rubycon 25THV330M10X10.5 and Panasonic EEE-TK1C331UP both specify 200mOhm @ 100kHz. The Panasonic EEE-TP1C331AP and EEE-TP1E331AP do not provide ESR specifications in the available data.

Q: What is the maximum ripple current for each substitute?

A: EEE-TP1E331AP and EEE-TP1C331AP: 500 mA @ 100 kHz. EEE-TK1C331UP: 270 mA @ 100 kHz. 25THV330M10X10.5: 500 mA @ 100 kHz. UCZ1E331MCL1GS: 500 mA @ 100 kHz. Applications requiring ripple current above 270 mA should avoid the EEE-TK1C331UP.
