Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LGN2P331MELY35 is determined by the following critical parameters:

Primary Substitution Criteria:

• Capacitance: 330 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Package / Case: Radial, Can - Snap-In (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lead Spacing: 0.394" (10.00 mm) (exact match required)
• Operating Temperature Range: -40°C ~ 105°C (exact match required)
• RoHS Status: RoHS3 Compliant (exact match required)

Secondary Substitution Criteria (Allowable Variations):

• Voltage - Rated: Equal to or greater than 220 V
• Physical Dimensions (Diameter, Height): Variations permitted within mechanical envelope constraints
• Ripple Current: Variations permitted if application requirements are met
• Series Designation: May differ (LGN, LGU, LGW series acceptable)

Substitute parts must maintain identical electrical performance at rated specifications while accommodating minor physical dimension variations that do not compromise mechanical fit in the target application.

Parameter Comparison

Engineering Selection Recommendations

LGN2E331MELY35 (Upgrade Substitute)

The LGN2E331MELY35 is classified as an upgrade substitute due to its elevated voltage rating of 250 V compared to the 220 V specification of the main part. This part maintains identical capacitance, tolerance, package configuration, and thermal specifications. The higher voltage rating provides increased design margin in applications where the 220 V rating is sufficient. Both parts carry Active product status and full RoHS3 compliance. Selection of this part is appropriate when higher voltage headroom is beneficial to system reliability.

LGN2P331MELZ25 (Similar Substitute)

The LGN2P331MELZ25 is classified as a similar substitute, matching the main part in all critical electrical parameters including capacitance, tolerance, voltage rating, and thermal performance. Physical dimensions differ, with increased diameter (0.866" vs. 0.787") and reduced height (1.063" vs. 1.457"). This part is suitable for applications where the smaller height envelope is advantageous, provided the increased diameter does not create mechanical conflicts. Both parts maintain Active status and RoHS3 compliance.

LGU2P331MELZ (Similar Substitute)

The LGU2P331MELZ is classified as a similar substitute from the LGU series, matching all critical electrical specifications of the main part. Physical dimensions show increased diameter (0.866" vs. 0.787") and slightly reduced height (1.378" vs. 1.457"). Ripple current specifications are marginally lower but remain within acceptable operational parameters. This part carries Active product status and RoHS3 compliance, making it suitable for general-purpose applications with identical electrical requirements.

All substitute parts maintain compliance with RoHS3 and REACH requirements, ensuring regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can LGN2E331MELY35 be used as a direct replacement for LGN2P331MELY35?

A: Yes. The LGN2E331MELY35 is electrically compatible as a direct replacement. The 250 V rating exceeds the 220 V requirement of the main part, providing additional voltage margin. All other critical parameters—capacitance, tolerance, package type, lead spacing, and thermal specifications—are identical. Physical dimensions are also identical, ensuring mechanical compatibility.

Q: What is the difference between LGN2P331MELZ25 and the main part LGN2P331MELY35?

A: Both parts share identical electrical specifications: 330 µF capacitance, ±20% tolerance, 220 V rating, and 3000 Hrs @ 105°C lifetime. The primary differences are physical dimensions. The LGN2P331MELZ25 has a larger diameter (0.866" vs. 0.787") but shorter height (1.063" vs. 1.457"). Selection depends on available space in the target application. Both maintain identical lead spacing (0.394") and mounting type (Through Hole).

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed—LGN2E331MELY35, LGN2P331MELZ25, and LGU2P331MELZ—carry RoHS3 compliance certification identical to the main part LGN2P331MELY35. All parts are also REACH unaffected.

Q: Can I use LGU2P331MELZ if the application requires higher ripple current?

A: The LGU2P331MELZ has slightly lower ripple current specifications (1.25 A @ 120 Hz and 1.875 A @ 50 kHz) compared to the main part (1.26 A @ 120 Hz and 1.89 A @ 50 kHz). If the application requires the higher ripple current values of the main part, LGU2P331MELZ may not be suitable. Verify application ripple current requirements before selection.

Q: What does "snap-in" package mean for these capacitors?

A: Snap-in refers to the mechanical mounting method. These radial, can-style capacitors feature leads spaced 0.394" (10.00 mm) apart for through-hole PCB mounting. The snap-in designation indicates the component is designed for secure mechanical retention on the PCB through the lead configuration.

Q: Are there any physical dimension constraints I should consider when selecting a substitute?

A: Yes. While all parts maintain identical lead spacing (0.394"), physical dimensions vary. The main part and LGN2E331MELY35 share identical diameter (0.787") and height (1.457"). The LGN2P331MELZ25 has larger diameter (0.866") but shorter height (1.063"). The LGU2P331MELZ has larger diameter (0.866") and intermediate height (1.378"). Verify available PCB space before selecting a substitute with different dimensions.

Q: What is the operating temperature range for all these parts?

A: All substitute parts operate across the identical temperature range: -40°C to 105°C. Lifetime rating is 3000 hours at the maximum operating temperature of 105°C for all parts.
