Substitute Part Grouping Explanation

Substitution of the LHT2W331MELC35 is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters establish the substitution criteria:

Electrical Parameters:

• Capacitance: 330 µF (exact match required)
• Voltage Rating: 450 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime: 3000 Hrs @ 125°C (exact match required)
• Operating Temperature Range: -40°C ~ 125°C (exact match required)
• Ripple Current @ 120 Hz: 1.51 A (exact match required)
• Ripple Current @ 50 kHz: 2.1593 A (exact match required)

Mechanical Parameters:

• Lead Spacing: 10.00 mm (exact match required)
• Diameter: 35.00 mm (exact match required)
• Height - Seated (Max): 37.50 mm (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can - Snap-In (exact match required)
• Polarization: Polar (exact match required)

Substitute parts must satisfy all parameters listed above to ensure direct compatibility in circuit design, PCB layout, and assembly processes without modification.

Parameter Comparison

Engineering Selection Recommendations

Both the LHT2W331MELC35 (Nichicon) and EGXA451VSN331MA35L (Chemi-Con) are active products with full ROHS3 compliance and identical electrical and mechanical specifications. Selection between these parts is based on the following engineering criteria:
