Key Parameters

Substitute Part Grouping Explanation

Substitution relationships for the LGU2P471MELZ are determined by the following critical parameters: capacitance value (470 µF), tolerance (±20%), polarization (Polar), lead spacing (10.00 mm), package type (Radial, Can - Snap-In), and mounting configuration (Through Hole). All substitute parts maintain these core electrical and mechanical specifications.

Substitute parts are grouped into two categories:

Upgrade Category: LGW2E471MELZ40 provides voltage rating elevation from 220 V to 250 V while maintaining identical capacitance, tolerance, lead spacing, and package configuration. This part is suitable for applications requiring higher voltage margin.

Equivalent Category: LGN2P471MELY45, LGU2P471MELA, and LGU2P471MELB maintain the 220 V voltage rating and all core electrical parameters. These parts differ in physical dimensions (diameter and height) while preserving the 10.00 mm lead spacing and snap-in package type. Selection among equivalent parts depends on available board space and mounting clearance requirements.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status with full RoHS3 compliance and REACH unaffected certification, ensuring regulatory alignment with the original LGU2P471MELZ specification.

LGW2E471MELZ40 is selected when circuit design permits operation at 250 V rated voltage. This upgrade provides enhanced voltage margin while maintaining identical capacitance, tolerance, lead spacing, and package configuration. Electrical performance parameters including ripple current ratings are proportionally increased.

LGN2P471MELY45, LGU2P471MELA, and LGU2P471MELB are selected based on available printed circuit board space and mounting clearance. All three maintain the 220 V voltage rating and identical electrical specifications. Physical dimension differences accommodate varying board layout constraints:

LGN2P471MELY45 features the smallest diameter (20.00 mm) with maximum height (47.00 mm), suitable for compact radial footprints with vertical clearance available.

LGU2P471MELA provides mid-range diameter (25.00 mm) with reduced height (35.00 mm), balancing footprint area with vertical space requirements.

LGU2P471MELB offers maximum diameter (30.00 mm) with minimum height (25.00 mm), appropriate for applications with limited vertical clearance and available horizontal board space.

Frequently Asked Questions (FAQ)

Q: Can LGW2E471MELZ40 be used as a direct replacement for LGU2P471MELZ?

A: Yes. LGW2E471MELZ40 maintains identical capacitance (470 µF), tolerance (±20%), lead spacing (10.00 mm), and package configuration (Radial, Can - Snap-In). The rated voltage increases from 220 V to 250 V, which is compatible with circuits designed for 220 V operation. Physical dimensions remain identical.

Q: What is the primary difference between LGN2P471MELY45, LGU2P471MELA, and LGU2P471MELB?

A: All three parts maintain identical electrical specifications (470 µF, ±20%, 220 V, 3000 Hrs @ 105°C). The differences are physical dimensions. LGN2P471MELY45 has a 20.00 mm diameter and 47.00 mm height. LGU2P471MELA has a 25.00 mm diameter and 35.00 mm height. LGU2P471MELB has a 30.00 mm diameter and 25.00 mm height. Selection depends on available board space and mounting clearance.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (LGW2E471MELZ40, LGN2P471MELY45, LGU2P471MELA, and LGU2P471MELB) are RoHS3 compliant and REACH unaffected, matching the compliance status of the original LGU2P471MELZ.

Q: Can substitute parts be used interchangeably on the same printed circuit board?

A: Substitution depends on physical dimensions and available board space. LGW2E471MELZ40 maintains identical dimensions to LGU2P471MELZ and can be used interchangeably. LGN2P471MELY45, LGU2P471MELA, and LGU2P471MELB have different diameter and height specifications and require verification of available mounting clearance before substitution.

Q: What is the lead spacing for all substitute parts?

A: All substitute parts maintain 0.394" (10.00 mm) lead spacing, identical to the original LGU2P471MELZ. This ensures compatibility with existing through-hole mounting patterns.

Q: Do substitute parts have the same operating temperature range?

A: Yes. All substitute parts operate across the -40°C to 105°C temperature range with 3000 hours rated lifetime at 105°C, matching the original LGU2P471MELZ specification.
