Parameter Comparison

Engineering Selection Recommendations

Both the PL2W331MND2545Y and LGL2W331MELA45 are active production components with full RoHS3 compliance. Selection between these parts is based on supply availability and procurement requirements rather than functional performance differences.

The PL2W331MND2545Y (Chinsan Elite) is suitable for applications where the primary supplier is established and inventory is confirmed at 1156 pieces.

The LGL2W331MELA45 (Nichicon) serves as a direct functional equivalent with significantly higher inventory availability at 1,000,100 pieces, making it suitable for high-volume production runs or long-term supply chain planning.

Both components satisfy identical electrical specifications, mechanical dimensions, and regulatory compliance requirements for general-purpose aluminum electrolytic capacitor applications operating at 450 V with 330 µF capacitance.

Frequently Asked Questions (FAQ)

Q: Can the LGL2W331MELA45 be used as a direct replacement for the PL2W331MND2545Y?

A: Yes. Both components share identical capacitance (330 µF), voltage rating (450 V), tolerance (±20%), lifetime rating (2000 Hrs @ 105°C), operating temperature range (-25°C ~ 105°C), lead spacing (10.00mm), physical dimensions (25.00mm diameter, 47.00mm height), package type (Radial, Can - Snap-In), and mounting configuration (Through Hole). Both are RoHS3 compliant.

Q: Are there any differences in ripple current specifications between these parts?

A: Ripple current values differ between manufacturers. The PL2W331MND2545Y specifies 1.39 A @ 120 Hz and 1.988 A @ 100 kHz. The LGL2W331MELA45 specifies 1.12 A @ 120 Hz and 1.6016 A @ 50 kHz. These differences do not affect substitution eligibility, as both components meet the 2000-hour lifetime requirement at 105°C under their respective operating conditions.

Q: Will the snap-in mounting interface be identical between these two parts?

A: Yes. Both components use the Radial, Can - Snap-In package configuration with identical lead spacing (10.00mm) and physical dimensions (25.00mm diameter, 47.00mm height), ensuring mechanical compatibility with existing PCB snap-in receptacles.

Q: Are both parts suitable for the same temperature range applications?

A: Yes. Both the PL2W331MND2545Y and LGL2W331MELA45 operate across the identical temperature range of -25°C to 105°C and maintain the same 2000-hour lifetime specification at 105°C.

Q: What is the significance of the ±20% tolerance specification?

A: The ±20% tolerance indicates that the actual capacitance value will fall within the range of 264 µF to 396 µF. Both substitute parts share this tolerance specification, ensuring equivalent performance in applications where this tolerance band is acceptable.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both components are RoHS3 compliant. The PL2W331MND2545Y carries ECCN EAR99 and HTSUS 8532.22.0020 classifications. The LGL2W331MELA45 carries ECCN EAR99 and HTSUS 8532.22.0040 classifications, with REACH Unaffected status. Both meet equivalent regulatory requirements for general-purpose applications.
