Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the EEE-TP1A331AV are qualified based on the following critical 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)
• Physical Dimensions: 0.394" Dia (10.00 mm) with compatible height and land size
• Operating Temperature Range: -40°C ~ 125°C (exact match required)
• Polarization: Polar (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Compliance: AEC-Q200, ROHS3, MSL 1

Substitutes are grouped into two categories:

Direct Manufacturer Substitutes: Parts with identical electrical specifications and mechanical compatibility, differing only in series designation or minor height variations within acceptable PCB assembly tolerances.

Parametric Equivalents: Parts meeting all critical electrical and mechanical parameters with enhanced ripple current ratings, providing superior performance margins in the same package footprint.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status and full AEC-Q200 automotive qualification. Selection between the main part and substitutes is determined by application-specific ripple current requirements and available inventory.

EEE-TC1A331P and EEE-TC1A331V provide 50% higher ripple current capacity (487.5 mA @ 120 Hz, 750 mA @ 100 kHz) compared to the main part, suitable for applications requiring enhanced thermal margin or higher AC stress tolerance. Height variation of 0.012" (0.30 mm) is within standard PCB assembly tolerances.

EEE-TP1A331AP maintains identical ripple current specifications to the main part with the same TP series designation. Height is reduced by 0.023" (0.60 mm), providing additional clearance in space-constrained layouts. ESR specification is not provided for this variant.

All parts comply with ROHS3, maintain MSL 1 rating, and are suitable for high-temperature reflow processes in automotive applications.

Frequently Asked Questions (FAQ)

Q: Can EEE-TC1A331P or EEE-TC1A331V be used as direct replacements for EEE-TP1A331AV?

A: Yes. Both parts meet all critical electrical parameters (330 µF, 10 V, ±20%, 3000 Hrs @ 125°C, AEC-Q200). The TC series variants offer higher ripple current ratings in identical package footprint with compatible land size (0.406" x 0.406"). Height difference of 0.012" is within standard SMD assembly tolerances.

Q: What is the difference between the TP and TC series?

A: Both series are Panasonic aluminum electrolytic capacitors with identical core electrical specifications for this part number. The TC series in these substitutes provides enhanced ripple current performance. Series designation does not affect mechanical compatibility or PCB assembly.

Q: Is EEE-TP1A331AP suitable if my design has height constraints?

A: Yes. EEE-TP1A331AP has a maximum seated height of 0.402" (10.20 mm), compared to 0.425" (10.80 mm) for the main part. This 0.023" reduction provides additional clearance. Ripple current specifications remain identical to the main part.

Q: Are all substitutes qualified for automotive applications?

A: Yes. All substitute parts carry AEC-Q200 rating and are specified for automotive and high-temperature reflow applications, matching the main part's qualification level.

Q: What is the significance of the Anti-Vibration designation?

A: Anti-Vibration indicates enhanced mechanical robustness for applications subject to vibration stress. EEE-TP1A331AV and EEE-TC1A331V both carry this designation. EEE-TC1A331P and EEE-TP1A331AP do not specify this feature but maintain full AEC-Q200 compliance.

Q: Can I substitute based on ripple current alone?

A: No. Substitution must be based on all critical parameters: capacitance, voltage rating, tolerance, package type, physical dimensions, operating temperature range, and compliance ratings. Ripple current is a secondary consideration for applications requiring enhanced thermal margin.

Q: Are there inventory considerations for these substitutes?

A: Yes. Current inventory levels are: EEE-TP1A331AV (1176 Pcs), EEE-TC1A331P (2099 Pcs), EEE-TP1A331AP (1114 Pcs), EEE-TC1A331V (1362 Pcs). Availability may influence selection for high-volume production.
