Substitute Part Grouping Explanation

Substitution of the LHT2W561MELC50 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 560 µF (exact match required)
• Voltage rating: 450 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime specification: 3000 Hrs @ 125°C (exact match required)
• Operating temperature range: -40°C ~ 125°C (exact match required)
• Ripple current ratings: 2.13 A @ 120 Hz and 3.0459 A @ 50 kHz (exact match required)

Mechanical Parameters:

• Lead spacing: 0.394" (10.00 mm) (exact match required)
• Case diameter: 1.378" (35.00 mm) (exact match required)
• Height (seated): 2.067" (52.50 mm) (exact match required)
• Mounting type: Through Hole (exact match required)
• Package style: Radial, Can - Snap-In (exact match required)

Compliance Parameters:

• RoHS3 compliance status (required for equivalent substitution)
• ECCN and HTSUS classifications (required for regulatory equivalence)

Only components matching all electrical, mechanical, and compliance parameters are classified as parametric equivalents. The EGXA451VSN561MA50L from Chemi-Con meets all substitution criteria.
