Substitute Part Grouping Explanation

Substitution of the UKL1A331MPDANATD is determined by the following critical parameters:

Capacitance Value: All substitutes maintain 330 µF
Voltage Rating: Substitutes operate at 16 V, 25 V, or higher, providing voltage margin above the original 10 V specification
Tolerance: All substitutes maintain ±20% tolerance
Physical Compatibility: Lead spacing (5.00 mm), case diameter (10.00 mm), and mounting type (Through Hole, Radial) are preserved across all substitutes
Polarization: All substitutes are polar aluminum electrolytic capacitors
Operating Temperature: All substitutes support the -40°C ~ 105°C range or extended range (-55°C ~ 105°C)

Substitutes are grouped by voltage rating and product status. Higher voltage ratings provide design margin and improved reliability. Active product status indicates current manufacturing availability.

Engineering Selection Recommendations

For Direct Replacement (Minimum Voltage Margin): ELXY160ETD331MJC5S provides the closest voltage specification at 16 V while maintaining full physical and electrical compatibility. This part is Active status and ROHS3 compliant. Operating temperature extends to -55°C, providing enhanced low-temperature performance.

For Enhanced Reliability (Increased Voltage Margin): EKZE250ETD331MJC5S and ELXZ250ETD331MJC5S both operate at 25 V, providing 2.5× voltage margin over the original specification. EKZE250ETD331MJC5S is manufactured by Chemi-Con with Active product status. ELXZ250ETD331MJC5S offers the longest lifetime rating at 5000 Hrs @ 105°C and extended operating temperature range (-55°C ~ 105°C), with AEC-Q200 automotive qualification.

For Nichicon Continuity: UHD1E331MPD6TD maintains Nichicon manufacturing while upgrading to 25 V rating and 4000 Hrs lifetime. Physical dimensions increase by 0.020" in height (14.00 mm vs. 14.60 mm), which must be verified for PCB clearance.

All substitutes are ROHS3 compliant and maintain the 5.00 mm lead spacing and 10.00 mm case diameter, ensuring PCB footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can ELXZ250ETD331MJC5S directly replace UKL1A331MPDANATD on the PCB? A: Yes. Both parts share identical lead spacing (5.00 mm), case diameter (10.00 mm), and Through Hole mounting. The height difference is 0.020" (0.50 mm), which does not affect standard PCB layouts. Verify clearance above the component if space is constrained.

Q: Why do substitute parts have higher voltage ratings? A: Higher voltage ratings provide design margin and improve capacitor reliability and lifetime. A 10 V capacitor operating at 10 V is at maximum stress; substitutes at 16 V or 25 V operate with reduced electrical stress, extending service life.

Q: What is the difference between EKZE250ETD331MJC5S and ELXZ250ETD331MJC5S? A: Both are 330 µF, 25 V, Radial, Can packages with identical physical dimensions. ELXZ250ETD331MJC5S offers superior lifetime (5000 Hrs vs. 4000 Hrs @ 105°C), extended operating temperature (-55°C ~ 105°C vs. -40°C ~ 105°C), and AEC-Q200 automotive qualification. EKZE250ETD331MJC5S is standard industrial grade.

Q: Is ELXY160ETD331MJC5S suitable for automotive applications? A: Yes. ELXY160ETD331MJC5S carries AEC-Q200 qualification and is rated for automotive use. It provides 16 V rating with 3000 Hrs lifetime @ 105°C and -55°C ~ 105°C operating range.
