Substitute Part Grouping Explanation

The LGN2E331MELA25 qualifies as a direct substitute for the LKX2E331MESA25 based on the following matching parameters:

• Capacitance: 330 µF (identical)
• Voltage Rating: 250 V (identical)
• Tolerance: ±20% (identical)
• Package Type: Radial, Can - Snap-In (identical)
• Lead Spacing: 0.394" (10.00 mm) (identical)
• Physical Dimensions: 0.984" Dia × 1.063" Height (identical)
• Mounting Type: Through Hole (identical)
• Operating Temperature Range: -40°C to 105°C (identical)
• Ripple Current Ratings: 1.2 A @ 120 Hz, 1.8 A @ 50 kHz (identical)
• RoHS3 Compliance: Confirmed for both parts

The primary distinction between these parts is the rated lifetime specification, where the substitute part offers extended operational life.

Parameter Comparison

Engineering Selection Recommendations

Both the LKX2E331MESA25 and LGN2E331MELA25 are active production parts from Nichicon with full RoHS3 and REACH compliance. The LGN2E331MELA25 provides extended lifetime rating (3000 hours at 105°C versus 2000 hours), making it suitable for applications requiring longer operational life under thermal stress. Both parts maintain identical electrical performance, mechanical compatibility, and regulatory certifications. Selection between these parts depends on application lifetime requirements and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the LGN2E331MELA25 be used as a direct replacement for the LKX2E331MESA25?

A: Yes. Both parts share identical capacitance (330 µF), voltage rating (250 V), tolerance (±20%), package configuration (radial snap-in), physical dimensions, lead spacing, mounting type, and ripple current specifications. They are mechanically and electrically interchangeable.

Q: What is the difference between these two parts?

A: The primary difference is the rated lifetime at 105°C. The LKX2E331MESA25 is rated for 2000 hours, while the LGN2E331MELA25 is rated for 3000 hours. Both parts operate across the same temperature range (-40°C to 105°C) and maintain identical performance characteristics.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the LKX2E331MESA25 and LGN2E331MELA25 are ROHS3 compliant and REACH unaffected.

Q: Will the substitute part fit in the same PCB footprint?

A: Yes. Both parts have identical lead spacing (0.394" / 10.00 mm), diameter (0.984" / 25.00 mm), and seated height (1.063" / 27.00 mm). They are mechanically compatible with the same through-hole PCB layout.

Q: Which part should I select for long-term reliability applications?

A: The LGN2E331MELA25 offers extended lifetime (3000 hours at 105°C) compared to the LKX2E331MESA25 (2000 hours at 105°C). For applications requiring extended operational life under thermal conditions, the LGN2E331MELA25 is the appropriate selection.
