EEE-TPA331UAP Equivalent & Substitute Parts

Part Overview

The EEE-TPA331UAP is a 330 µF, 10 V aluminum electrolytic capacitor in surface mount radial can package manufactured by Panasonic Electronic Components. This component is rated for automotive and high temperature reflow applications with AEC-Q200 compliance and a 2000-hour lifetime at 125°C. The part is currently active in production and available in Tape & Reel packaging. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the allowed parameter range for this capacitor category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EEE-TPA331UAP is determined by strict equivalence in the following parameters:

• Capacitance: 330 µF (exact match required)
• Voltage Rating: 10 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package / Case: Radial, Can - SMD (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Size / Dimension: 0.315" Dia (8.00mm) (exact match required)
• Height - Seated (Max): 0.402" (10.20mm) (exact match required)
• Surface Mount Land Size: 0.327" L x 0.327" W (8.30mm x 8.30mm) (exact match required)
• Operating Temperature Range: -40°C ~ 125°C (exact match required)
• Polarization: Polar (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Variations in series designation, ESR specifications, ripple current ratings, lifetime at temperature, and packaging format (Tape & Reel vs. Cut Tape) do not disqualify substitution when all primary electrical and mechanical parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

EEE-TG1A331UP and EEE-TK1A331UP are direct substitutes for the EEE-TPA331UAP in applications where mechanical fit and electrical specifications are the primary selection criteria. Both parts maintain identical capacitance, voltage rating, tolerance, package dimensions, and land size. EEE-TG1A331UP carries AEC-Q200 automotive qualification matching the original part. EEE-TK1A331UP provides extended lifetime (3000 hours at 125°C versus 2000 hours) but does not carry AEC-Q200 rating and is designated for general purpose applications.

EEE-TP1A331AP is not a direct substitute due to dimensional incompatibility. This part features a larger case size (0.394" diameter versus 0.315" diameter) and larger land size (0.406" x 0.406" versus 0.327" x 0.327"), which prevents direct board-level replacement without PCB redesign.

For automotive applications requiring AEC-Q200 compliance, EEE-TG1A331UP is the appropriate substitute. For general purpose applications where extended lifetime is beneficial and automotive qualification is not required, EEE-TK1A331UP is suitable. All substitute parts maintain ROHS3 compliance and unlimited moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can EEE-TP1A331AP replace EEE-TPA331UAP on the same PCB?

A: No. EEE-TP1A331AP has a larger case diameter (0.394" versus 0.315") and larger land size (0.406" x 0.406" versus 0.327" x 0.327"). Direct substitution on existing PCB layouts is not possible without redesign.

Q: What is the difference between EEE-TG1A331UP and EEE-TK1A331UP?

A: Both parts are mechanically and electrically equivalent to EEE-TPA331UAP. EEE-TG1A331UP carries AEC-Q200 automotive qualification and is packaged in Cut Tape & Digi-Reel format. EEE-TK1A331UP offers extended lifetime (3000 hours at 125°C) but lacks AEC-Q200 rating and is designated for general purpose applications. Selection depends on application requirements and qualification needs.

Q: Are packaging format differences (Tape & Reel vs. Cut Tape) significant for substitution?

A: Packaging format affects handling and supply chain logistics but does not impact electrical or mechanical compatibility. EEE-TG1A331UP in Cut Tape & Digi-Reel format is functionally equivalent to EEE-TPA331UAP in Tape & Reel format for board-level assembly.

Q: Does the difference in ripple current ratings affect substitution suitability?

A: Ripple current specifications indicate the maximum AC current the capacitor can handle at specified frequencies. EEE-TP1A331AP has higher ripple current ratings (325 mA @ 120 Hz, 500 mA @ 100 kHz) compared to EEE-TPA331UAP (
