Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LGN2Z331MELY25 is determined by strict equivalence across the following critical parameters:

Electrical equivalence requires identical capacitance (330 µF), tolerance (±20%), and rated voltage (180 V). All substitute parts must maintain the same lifetime specification (3000 Hrs @ 105°C) and operating temperature range (-40°C ~ 105°C) to ensure functional compatibility in the target application.

Mechanical compatibility is established through matching lead spacing (0.394" / 10.00 mm), mounting type (Through Hole), and package classification (Radial, Can - Snap-In). Physical dimensions (diameter and height) may vary within the snap-in package envelope without affecting electrical performance, provided the component fits within the PCB layout constraints.

Compliance requirements mandate that all substitute parts maintain ROHS3 compliance and REACH unaffected status to meet regulatory standards.

The identified substitute parts LGU2Z331MELY and LGU2Z331MELZ meet all electrical and mechanical substitution criteria. Both components are manufactured by Nichicon, share identical electrical specifications, and are classified as Active product status.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain Active product status and full compliance with ROHS3 and REACH requirements, ensuring regulatory alignment with the original component.

LGU2Z331MELY is electrically and mechanically equivalent to LGN2Z331MELY25 with identical diameter (20.00 mm) and lead spacing. The height difference (30.00 mm vs. 27.00 mm) represents a 3 mm increase in seated height. This dimension variance is acceptable for applications where vertical clearance permits the additional height within the snap-in package envelope.

LGU2Z331MELZ is electrically equivalent with identical electrical specifications and lead spacing. Physical dimensions differ in both diameter (22.00 mm vs. 20.00 mm) and height (25.00 mm vs. 27.00 mm). The increased diameter requires verification of radial clearance on the PCB, while the reduced height provides improved vertical fit for space-constrained layouts.

Selection between substitute parts depends on available PCB layout space and mechanical constraints. Both substitutes are manufactured by Nichicon and carry identical electrical performance ratings.

Frequently Asked Questions (FAQ)

Q: Can LGU2Z331MELY be used as a direct replacement for LGN2Z331MELY25?

A: Yes. Both components share identical electrical specifications (330 µF, 180 V, ±20% tolerance, 3000 Hrs @ 105°C) and lead spacing (10.00 mm). The seated height difference (30.00 mm vs. 27.00 mm) requires verification that the additional 3 mm vertical clearance is available on the PCB.

Q: What are the mechanical differences between the substitute parts?

A: LGU2Z331MELY maintains the same diameter as the main part (20.00 mm) but increases height to 30.00 mm. LGU2Z331MELZ reduces height to 25.00 mm but increases diameter to 22.00 mm. Both maintain the same lead spacing (10.00 mm) and snap-in package type.

Q: Are all parts compliant with current regulatory standards?

A: Yes. The main part and both substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: Do the substitute parts have the same ripple current ratings?

A: Yes. All three parts are rated for 1.2 A ripple current at 120 Hz and 1.8 A ripple current at 50 kHz, ensuring equivalent performance in AC ripple applications.

Q: What is the lead spacing for all parts?

A: All parts, including the main component and substitutes, have a lead spacing of 0.394 inches (10.00 mm), ensuring compatibility with standard PCB hole patterns designed for this spacing.

Q: Can physical dimension differences affect circuit performance?

A: No. The electrical performance of aluminum electrolytic capacitors is determined by capacitance, voltage rating, tolerance, and temperature specifications. Physical dimension variations within the snap-in package envelope do not affect electrical characteristics, provided the component physically fits within the PCB layout constraints.
