Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Electrical Parameters (Must Match or Exceed):

• Capacitance: 330 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: 25 V minimum (higher ratings acceptable as upgrades)
• Operating Temperature: Must support -40°C to 125°C minimum

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole
• Package / Case: Radial, Can
• Lead Spacing: 0.197" (5.00mm)
• Size / Dimension: 0.394" Dia (10.00mm)

Performance Parameters (Acceptable Variations):

• Lifetime @ 125°C: 2000 Hrs minimum (higher values acceptable)
• Ripple Current: Higher values acceptable
• Impedance: Variations acceptable if electrical performance maintained

Three substitute parts meet these criteria with enhanced performance characteristics in specific areas.

Parameter Comparison

Engineering Selection Recommendations

EEU-TP1E331 (Panasonic TP-A Series): This substitute provides extended lifetime (3000 Hrs @ 125°C) and elevated maximum operating temperature (135°C). It carries AEC-Q200 automotive qualification and is suitable for applications requiring enhanced thermal performance. Height increases from 17.00mm to 17.50mm; verify PCB layout clearance.

EGXL250ELL331MJ16S (Chemi-Con GXL Series): This substitute delivers the highest lifetime rating (5000 Hrs @ 125°C) and highest ripple current capacity (1.05 A @ 100 kHz). It holds AEC-Q200 automotive qualification. Height increases to 17.50mm; verify PCB layout clearance.

MAL214650331E3 (Vishay Beyschlag 146 RTI Series): This substitute features elevated voltage rating (35 V) and extended operating temperature range (-55°C to 125°C). It carries AEC-Q200 automotive qualification and 2500-hour lifetime at 125°C. Height increases to 17.50mm; verify PCB layout clearance. The higher voltage rating provides additional design margin in applications with voltage transients.

All substitute parts maintain RoHS3 compliance and Active product status. Selection depends on specific application requirements for thermal performance, lifetime, voltage margin, and temperature range.

Frequently Asked Questions (FAQ)

Q: Can EEU-TP1E331 replace EEU-TA1E331 in all applications? A: EEU-TP1E331 is electrically and mechanically compatible. It provides superior lifetime (3000 vs 2000 hours) and higher maximum operating temperature (135°C vs 125°C). The height difference (17.50mm vs 17.00mm) requires PCB layout verification. Applications benefit from extended thermal performance.

Q: What is the voltage rating difference between EEU-TA1E331 and MAL214650331E3? A: EEU-TA1E331 is rated 25 V; MAL214650331E3 is rated 35 V. Both operate at 25 V in the same circuit. The higher rating in MAL214650331E3 provides additional voltage margin and is suitable for applications with potential transient overvoltage conditions.

Q: Are all substitute parts automotive-qualified? A: EEU-TP1E331, EGXL250ELL331MJ16S, and MAL214650331E3 all carry AEC-Q200 automotive qualification. EEU-TA1E331 is general-purpose without automotive rating.

Q: What is the maximum height constraint for PCB layout? A: EEU-TA1E331 seated height is 17.00mm. All three substitutes have 17.50mm seated height. Verify 0.50mm additional clearance in PCB design before substitution.

Q: Which substitute offers the longest operational lifetime? A: EGXL250ELL331MJ16S provides 5000 hours at 125°C, compared to 2000 hours for EEU-TA1E331, 3000 hours for EEU-TP1E331, and 2500 hours for MAL214650331E3.

Q: Are all parts RoHS3 compliant? A: Yes. EEU-TA1E331, EEU-TP1E331, EGXL250ELL331MJ16S, and MAL214650331E3 are all RoHS3 compliant.
