Substitute Part Grouping Explanation

Substitution eligibility for the UBT1E331MPD8 is determined by strict equivalence across the following critical parameters:

• Capacitance value: 330 µF (exact match required)
• Voltage rating: 25 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)
• Physical dimensions: 0.394" Dia (10.00 mm) (exact match required)
• Operating temperature range: -40°C ~ 125°C (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

The EGXL250ELL331MJ16S manufactured by Chemi-Con meets all critical electrical and mechanical parameters for direct substitution. This part maintains identical capacitance, voltage rating, tolerance, polarization, package configuration, and mounting specifications. Physical dimensions remain compatible with existing PCB layouts and mechanical assemblies.

Parameter Comparison

Engineering Selection Recommendations

Both the UBT1E331MPD8 and EGXL250ELL331MJ16S are active production parts with ROHS3 compliance, suitable for automotive applications. The EGXL250ELL331MJ16S carries AEC-Q200 qualification, which provides additional assurance for automotive-grade reliability. The seated height difference of 0.020" (0.50 mm) is within typical PCB layout tolerances for through-hole radial capacitors. Both parts satisfy the specified electrical and mechanical requirements for direct substitution in automotive circuit designs.

Frequently Asked Questions (FAQ)

Q: Can EGXL250ELL331MJ16S replace UBT1E331MPD8 in existing designs?

A: Yes. Both parts share identical capacitance (330 µF), voltage rating (25 V), tolerance (±20%), polarization (polar), package type (radial can), mounting method (through hole), and lead spacing (5.00 mm). Physical dimensions are compatible with existing PCB layouts.

Q: What is the significance of the AEC-Q200 rating on the EGXL250ELL331MJ16S?

A: AEC-Q200 is an automotive electronics qualification standard. This certification indicates the part meets automotive industry reliability and quality requirements. The UBT1E331MPD8 does not carry this designation.

Q: Are there differences in electrical performance between these parts?

A: The EGXL250ELL331MJ16S exhibits higher ripple current ratings (525 mA @ 120 Hz and 1.05 A @ 100 kHz) compared to the UBT1E331MPD8 (472.5 mA @ 120 Hz and 945 mA @ 100 kHz). The UBT1E331MPD8 has lower impedance (75 mOhms versus 120 mOhms). Both parts meet the specified 5000-hour lifetime at 125°C.

Q: Will the height difference affect PCB assembly?

A: The EGXL250ELL331MJ16S seated height is 0.689" (17.50 mm) versus 0.709" (18.00 mm) for the UBT1E331MPD8. This 0.020" (0.50 mm) difference is within standard through-hole component tolerances and does not require PCB layout modifications.

Q: Are both parts suitable for automotive applications?

A: Yes. Both parts are designated for automotive applications and maintain ROHS3 compliance. The EGXL250ELL331MJ16S includes AEC-Q200 qualification for enhanced automotive reliability assurance.
