Substitute Part Grouping Explanation

Substitution for the LGGW6331MELA45 is determined by the following criteria:

Electrical Parameters (Must Match or Exceed):

Capacitance: 330 µF (±20% tolerance)
Voltage Rating: 420 V minimum
Operating Temperature Range: -25°C ~ 105°C
Polarization: Polar

Mechanical Parameters (Must Match):

Package Type: Radial, Can - Snap-In
Mounting Type: Through Hole
Lead Spacing: 0.394" (10.00 mm)

Compliance Parameters (Must Match):

RoHS Status: ROHS3 Compliant
REACH Status: REACH Unaffected

Substitute parts are grouped into two categories: Upgrade (higher voltage rating) and Similar (same voltage rating with enhanced lifetime or dimensional variations).

Engineering Selection Recommendations

LGL2W331MELA45 (Upgrade Option): This part provides identical mechanical dimensions and lead spacing to the LGGW6331MELA45 while offering a 30 V higher voltage rating (450 V vs. 420 V). Both parts maintain ROHS3 compliance and identical lifetime specifications. This substitution is suitable for applications requiring increased voltage margin without PCB layout modifications.

LGUW6331MELB and LGUW6331MELC (Similar Options): Both parts maintain the 420 V voltage rating and 330 µF capacitance of the original part while providing extended lifetime (3000 Hrs @ 105°C vs. 2000 Hrs). These parts differ in physical dimensions (diameter and height), requiring verification of available PCB space. Lead spacing remains constant at 0.394" (10.00 mm). Both maintain ROHS3 compliance and are suitable for applications where increased thermal endurance is beneficial.

All substitute parts are Active status products with full ROHS3 and REACH compliance matching the original specification.

Frequently Asked Questions (FAQ)

Q: Can LGL2W331MELA45 be used as a direct replacement for LGGW6331MELA45?

A: Yes. The LGL2W331MELA45 maintains identical capacitance (330 µF), tolerance (±20%), lead spacing (10.00 mm), and physical dimensions. The 450 V rating exceeds the 420 V requirement, providing additional voltage margin. No PCB modifications are required.

Q: What is the difference between the upgrade and similar substitute categories?

A: The upgrade category (LGL2W331MELA45) provides higher voltage rating with identical physical dimensions. The similar category (LGUW6331MELB and LGUW6331MELC) maintains the same voltage rating but offers extended lifetime and different physical dimensions. Selection depends on application voltage requirements and available PCB space.

Q: Do LGUW6331MELB and LGUW6331MELC have different mechanical compatibility?

A: Both maintain the same lead spacing (10.00 mm) and mounting type (Through Hole, Radial Can - Snap-In). However, they differ in diameter and height. LGUW6331MELB is 1.181" diameter × 1.772" height, while LGUW6331MELC is 1.378" diameter × 1.378" height. PCB layout verification is required before selection.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts (LGL2W331MELA45, LGUW6331MELB, LGUW6331MELC) maintain ROHS3 compliance and REACH Unaffected status, matching the original LGGW6331MELA45 specification.

Q: What determines whether a part can substitute for LGGW6331MELA45?

A: Substitution is determined by: matching capacitance (330 µF ±20%), voltage rating of 420 V or higher, identical lead spacing (10.00 mm), compatible package type (Radial, Can - Snap-In), Through Hole mounting, and maintained RoHS3 compliance. Physical dimensions must be verified against available PCB space.
