EEU-TA1V331B Equivalent & Substitute Parts

Part Overview

The EEU-TA1V331B is a 330 µF, 35 V aluminum electrolytic capacitor in radial 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 and ROHS3 compliant.

Substitute parts are identified when equivalent electrical specifications (capacitance, voltage rating, tolerance, and polarization) are maintained while offering alternative performance characteristics such as extended lifetime ratings, improved temperature ranges, or enhanced ripple current handling. Identifying qualified substitutes ensures design flexibility and supply chain resilience.

Substitute Part Grouping Explanation

Substitution eligibility for the EEU-TA1V331B is determined by the following mandatory parameters:

Capacitance: 330 µF (exact match required)
Voltage Rating: 35 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Package Type: Radial, Can (exact match required)
Mounting Type: Through Hole (exact match required)
Lead Spacing: 0.197" (5.00 mm) (exact match required)
Size / Dimension: 0.394" Dia (10.00 mm) (exact match required)

All three substitute parts meet these mandatory criteria. Secondary parameters such as lifetime rating, operating temperature range, ripple current capacity, and impedance may vary and are documented for engineering selection purposes.

Engineering Selection Recommendations

All three substitute parts maintain full electrical equivalence to the EEU-TA1V331B across mandatory parameters. Selection among substitutes is based on application requirements and compliance certifications:

EEU-TP1V331B offers extended lifetime (3000 hours at 125°C) and expanded operating temperature range (-40°C to 135°C) with AEC-Q200 automotive qualification. This part is suitable for automotive applications requiring enhanced thermal performance.

EGXL350ETD331MJ20S provides the highest lifetime rating (5000 hours at 125°C) and superior high-frequency ripple current capacity (1.3 A at 100 kHz) with AEC-Q200 automotive qualification. This part is suitable for demanding automotive applications with extended service life requirements.

UBW1V331MPD1TD extends the operating temperature range to -55°C to 135°C and offers the lowest impedance (75 mOhms) among all options. This part is suitable for applications requiring extreme temperature operation. REACH status is affected for this part.

All parts are ROHS3 compliant and currently in active production status.

Frequently Asked Questions (FAQ)

Q: Can EEU-TP1V331B replace EEU-TA1V331B in any application?

A: Yes, provided the application does not require the specific packaging format (Tape & Box). EEU-TP1V331B is supplied in Cut Tape format. All electrical and mechanical parameters are compatible.

Q: What is the primary difference between the substitute parts?

A: The primary differences are lifetime rating at temperature, operating temperature range, and ripple current capacity. EEU-TP1V331B offers 3000-hour lifetime; EGXL350ETD331MJ20S offers 5000-hour lifetime; UBW1V331MPD1TD extends the lower temperature limit to -55°C.

Q: Are all substitute parts suitable for automotive applications?

A: EEU-TP1V331B and EGXL350ETD331MJ20S carry AEC-Q200 automotive qualification. UBW1V331MPD1TD does not carry AEC-Q200 rating but is designated for automotive applications. The original EEU-TA1V331B is designated for general-purpose applications.

Q: Does the height difference between EGXL350ETD331MJ20S (0.846") and other parts (0.866") affect compatibility?

A: The 0.020" (0.50 mm) height difference is within typical PCB design tolerances for through-hole radial capacitors. Verify clearance in your specific board layout.

Q: What does ROHS3 compliance mean?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting the use of specific hazardous materials in electrical and electronic equipment.

Q: Can I use UBW1V331MPD1TD in applications requiring REACH compliance?

A: UBW1V331MPD1TD has REACH status listed as affected. Verify REACH compliance requirements for your specific application and regulatory jurisdiction before selection.
