Substitute Part Grouping Explanation

Substitution eligibility for the LKX2D331MESY35 is determined by the following critical parameters:

Capacitance value: 330 µF (exact match required)
Tolerance: ±20% (exact match required)
Voltage rating: Equal to or greater than 200 V
Package type: Radial, Can - Snap-In (exact match required)
Lead spacing: 10.00 mm (exact match required)
Physical dimensions: 20.00 mm diameter, 37.00 mm height maximum (exact match required)
Mounting type: Through Hole (exact match required)
Polarization: Polar (exact match required)
Operating temperature range: -40°C ~ 105°C (exact match required)

The substitute part LGN2E331MELY35 meets all substitution criteria with identical electrical and mechanical specifications, with the exception of an elevated voltage rating (250 V versus 200 V) and extended lifetime rating (3000 Hrs @ 105°C versus 2000 Hrs @ 105°C).

Engineering Selection Recommendations

Both the LKX2D331MESY35 and LGN2E331MELY35 maintain Active product status and are RoHS3 compliant. The LGN2E331MELY35 substitute provides equivalent electrical performance with identical capacitance, tolerance, ripple current ratings, and operating temperature specifications. The elevated voltage rating of 250 V in the substitute part provides additional voltage margin over the 200 V requirement of the main part. The extended lifetime rating of 3000 hours at 105°C in the substitute part exceeds the 2000-hour specification of the main part. Both parts are manufactured by Nichicon and share identical mechanical dimensions and through-hole mounting configuration, ensuring direct board-level compatibility.

Frequently Asked Questions (FAQ)

Q: Can LGN2E331MELY35 be used as a direct replacement for LKX2D331MESY35?

A: Yes. The LGN2E331MELY35 meets all mechanical and electrical substitution criteria. Identical capacitance (330 µF), tolerance (±20%), ripple current ratings, operating temperature range, lead spacing, and physical dimensions ensure direct compatibility. The higher voltage rating and extended lifetime are additional benefits that do not compromise compatibility.

Q: What is the significance of the voltage rating difference between the two parts?

A: The LGN2E331MELY35 is rated for 250 V compared to the 200 V rating of the LKX2D331MESY35. In circuit applications operating at or below 200 V, the higher voltage rating of the substitute part provides additional safety margin and does not negatively impact performance.

Q: Are the physical dimensions identical between the main part and substitute?

A: Yes. Both parts share identical lead spacing (10.00 mm), diameter (20.00 mm), and maximum seated height (37.00 mm). Both are packaged as radial, can snap-in components with through-hole mounting, ensuring identical PCB footprint compatibility.

Q: What does the lifetime rating difference indicate?

A: The LGN2E331MELY35 is rated for 3000 hours at 105°C compared to 2000 hours for the LKX2D331MESY35. This indicates extended operational life under thermal stress conditions. For applications requiring extended service life or operating in elevated temperature environments, the substitute part provides improved reliability.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the LKX2D331MESY35 and LGN2E331MELY35 are RoHS3 compliant and meet environmental regulatory requirements for electronic component manufacturing and use.
