Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LNT2G221MSECBN is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters for Substitution:

• Capacitance value: 220 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Package / Case: Radial, Can - Screw Terminals (exact match required)
• Mounting Type: Chassis Mount (exact match required)
• Lead Spacing: 0.500" (12.70mm) (exact match required)
• Physical Dimensions: 1.378" Dia (35.00mm) and 3.268" Height (exact match required)
• Operating Temperature Range: -25°C ~ 105°C (exact match required)
• Lifetime @ Temperature: 5000 Hrs @ 105°C (exact match required)

Allowable Variation Parameters:

• Voltage - Rated: May be equal to or higher than 400 V
• Ripple Current: May be equal to or higher than specified values

The LNT2W221MSEC qualifies as a direct substitute because it maintains all critical parameters while providing an upgraded voltage rating (450 V vs. 400 V) and enhanced ripple current specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the LNT2G221MSECBN and LNT2W221MSEC are active products with ROHS3 compliance and REACH compliance status. The LNT2W221MSEC provides a direct mechanical and electrical substitute with the following characteristics:

The upgraded voltage rating of 450 V in the LNT2W221MSEC provides additional voltage margin over the 400 V specification of the main part. This higher voltage rating does not affect circuit compatibility in applications designed for 400 V operation, as the substitute part maintains identical capacitance, tolerance, physical dimensions, and thermal characteristics.

The enhanced ripple current specifications (1.8 A @ 120 Hz and 2.52 A @ 10 kHz) in the LNT2W221MSEC represent improved performance headroom compared to the main part specifications (1.6 A @ 120 Hz and 2.24 A @ 10 kHz).

Both parts share identical mechanical mounting requirements, lead spacing, and package configuration, ensuring direct board-level compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can the LNT2W221MSEC be used as a direct replacement for the LNT2G221MSECBN?

A: Yes. The LNT2W221MSEC maintains identical capacitance (220 µF), tolerance (±20%), physical dimensions (1.378" diameter, 3.268" height), lead spacing (0.500"), package type (Radial, Can - Screw Terminals), and mounting configuration
