Key Parameters

Substitute Part Grouping Explanation

Substitution relationships for the LGUW6820MELY are determined by the following criteria:

Direct Substitutes maintain identical electrical specifications (82 µF, 420 V, ±20% tolerance, 3000 Hrs @ 105°C) with allowable variations in physical dimensions and series designation. These parts are interchangeable in applications where the original footprint and height constraints are not restrictive.

Upgrade Substitutes increase the voltage rating to 450 V while maintaining all other electrical parameters (82 µF, ±20% tolerance, 3000 Hrs @ 105°C). These parts provide enhanced voltage margin and are suitable for applications where the circuit can accommodate higher voltage-rated components without redesign.

Similar Substitutes maintain the same electrical specifications but may have different physical dimensions (diameter and height). These parts are suitable when PCB layout allows for dimensional variation.

All substitute parts share the following mandatory parameters with the main part:

• Capacitance: 82 µF
• Tolerance: ±20%
• Polarization: Polar
• Mounting Type: Through Hole
• Package / Case: Radial, Can - Snap-In
• Lead Spacing: 0.394" (10.00mm)
• Lifetime @ Temperature: 3000 Hrs @ 105°C
• Operating Temperature: -25°C ~ 105°C

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, meeting the same regulatory and environmental standards as the main part LGUW6820MELY.

For direct replacement in existing designs: LGNW6820MELY25 provides identical electrical performance with reduced height (27.00 mm vs. 35.00 mm), suitable for space-constrained applications. LGUW6820MELZ offers the same electrical specifications with different physical dimensions (22.00 mm diameter, 25.00 mm height).

For voltage margin enhancement: LGN2W820MELY30 and LGU2W820MELY both upgrade the voltage rating to 450 V while maintaining the 82 µF capacitance and ±20% tolerance. LGU2W820MELY preserves the original height of 35.00 mm, while LGN2W820MELY30 reduces height to 32.00 mm.

For inventory and availability: All substitute parts are available in stock quantities ranging from 828 to 1037 pieces.

Frequently Asked Questions (FAQ)

Q: Can LGNW6820MELY25 be used as a direct replacement for LGUW6820MELY?

A: Yes. Both parts share identical electrical specifications (82 µF, 420 V, ±20% tolerance, 3000 Hrs @ 105°C) and the same lead spacing (10.00 mm). The primary difference is height: LGNW6820MELY25 is 27.00 mm tall versus 35.00 mm for LGUW6820MELY. Verify PCB clearance before substitution.

Q: What is the advantage of upgrading to 450 V rated parts?

A: The 450 V rated substitutes (LGN2W820MELY30 and LGU2W820MELY) provide additional voltage margin above the original 420 V specification. These parts are suitable for applications where circuit voltage may approach or occasionally exceed 420 V, or where design margin is required.

Q: Are there dimensional constraints when selecting a substitute?

A: Yes. The main part LGUW6820MELY has a diameter of 20.00 mm and height of 35.00 mm. LGNW6820MELY25 reduces height to 27.00 mm. LGUW6820MELZ increases diameter to 22.00 mm and reduces height to 25.00 mm. Verify PCB layout and component clearance before substitution.

Q: Do all substitute parts have the same lead spacing?

A: Yes. All listed parts maintain 0.394" (10.00 mm) lead spacing, ensuring compatibility with existing PCB footprints.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant and meet the same environmental and regulatory standards as the main part.
