Substitute Part Grouping Explanation

Substitution eligibility for the UBT1V331MPD8 is determined by strict equivalence across the following critical parameters:

• Capacitance value: 330 µF (exact match required)
• Rated voltage: 35 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Lead spacing: 0.197" (5.00mm) (exact match required)
• Physical dimensions: 0.394" Dia (10.00mm) (exact match required)
• Mounting type: Through Hole (exact match required)
• Package type: Radial, Can (exact match required)
• Operating temperature range: -40°C ~ 125°C (exact match required)
• Lifetime rating: 5000 Hrs @ 125°C (exact match required)

The substitute part EGXL350ELL331MJ20S from Chemi-Con meets all critical electrical and mechanical parameters, confirming direct substitutability in the same application context.

Parameter Comparison

Engineering Selection Recommendations

Both UBT1V331MPD8 and EGXL350ELL331MJ20S are active production parts with ROHS3 compliance. The Chemi-Con EGXL350ELL331MJ20S carries AEC-Q200 automotive qualification, meeting stringent automotive reliability standards. The substitute part exhibits higher ripple current ratings and is suitable for applications requiring enhanced thermal performance. The height difference of 0.02" (0.50mm) is within typical PCB layout tolerances for through-hole radial capacitors. Both parts are electrically and mechanically interchangeable for the specified application requirements.

Frequently Asked Questions (FAQ)

Q: Can EGXL350ELL331MJ20S replace UBT1V331MPD8 in existing designs?

A: Yes. Both parts share identical capacitance, voltage rating, tolerance, operating temperature range, lifetime rating, lead spacing, and physical diameter. The height difference of 0.02" (0.50mm) is negligible for through-hole mounting and does not affect PCB layout compatibility.

Q: What are the key differences between these parts?

A: The substitute part features higher ripple current capability (650 mA @ 120 Hz vs. 475 mA; 1.3 A @ 100 kHz vs. 950 mA) and carries AEC-Q200 automotive qualification. Impedance differs slightly (94 mOhms vs. 75 mOhms). These differences do not affect substitutability for equivalent electrical performance.

Q: Are both parts suitable for automotive applications?

A: Yes. Both parts are rated for automotive use. The Chemi-Con part carries explicit AEC-Q200 certification, confirming compliance with automotive reliability and qualification requirements.

Q: What is the impact of the impedance difference?

A: The impedance difference (75 mOhms vs. 94 mOhms) is within acceptable variation for aluminum electrolytic capacitors of this class and does not compromise circuit performance in standard automotive applications.

Q: Are there any compliance or regulatory differences?

A: Both parts are ROHS3 compliant. The Chemi-Con part is REACH Unaffected, while the Nichicon part is REACH Affected. Both carry EAR99 ECCN classification and share the same HTSUS code (8532.22.0020).
