LAK2D331MELB25 Equivalent & Substitute Parts

Part Overview

The LAK2D331MELB25 is a 330 µF, 200 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by Nichicon. This component is rated for 2000 hours at 105°C and is designed for general-purpose applications requiring through-hole mounting. The part is currently active in production with ROHS3 compliance and REACH unaffected status. Substitute parts are identified when design requirements allow for higher voltage ratings, extended operational lifetime, or improved ripple current handling while maintaining identical physical dimensions and electrical capacitance values.

Parameter Comparison

Engineering Selection Recommendations

The LGR2E331MELB25 is a direct mechanical and electrical substitute for the LAK2D331MELB25. Both parts are manufactured by Nichicon, maintain identical physical dimensions and lead spacing, and are ROHS3 compliant with REACH unaffected status. The substitute part offers higher voltage rating (250 V vs. 200 V), extended operational lifetime (10000 Hrs vs. 2000 Hrs at 105°C), and improved ripple current handling across frequency ranges. Both parts are active in production status. Selection between these parts depends on circuit voltage requirements and expected operational lifetime specifications.

Frequently Asked Questions (FAQ)

Q: Can the LGR2E331MELB25 be used in place of the LAK2D331MELB25?

A: Yes. Both parts share identical capacitance (330 µF), tolerance (±20%), physical dimensions (1.181" diameter, 1.063" height), lead spacing (10.00mm), and package type (radial, can snap-in). The substitute part is mechanically and electrically compatible for through-hole mounting applications.

Q: What are the key differences between these parts?

A: The LGR2E331MELB25 provides higher voltage rating (250 V vs. 200 V), longer operational lifetime (10000 Hrs vs. 2000 Hrs at 105°C), extended lower temperature operating range (-40°C vs. -25°C minimum), and higher ripple current capacity at both low and high frequencies.

Q: Are both parts compliant with environmental regulations?

A: Yes. Both the LAK2D331MELB25 and LGR2E331MELB25 are ROHS3 compliant and REACH unaffected.

Q: Do these parts require different PCB footprints?

A: No. Both parts have identical lead spacing (10.00mm) and physical dimensions, requiring no PCB layout modifications for substitution.

Q: Which part should be selected for new designs?

A: Selection is based on circuit voltage requirements and expected operational lifetime. If the circuit operates at or below 200 V and 2000-hour lifetime is acceptable, either part is suitable. If higher voltage margin or extended lifetime is required, the LGR2E331MELB25 is the appropriate choice.
