LHT2W271MELC30 Equivalent & Substitute Parts

Part Overview

The LHT2W271MELC30 is a 270 µF, 450 V aluminum electrolytic capacitor manufactured by Nichicon in the LHT series. This radial, can-style snap-in capacitor is designed for general-purpose applications requiring high voltage energy storage and filtering. The component features a rated lifetime of 3000 hours at 125°C and operates across a temperature range of -40°C to 125°C. As an active product with ROHS3 compliance, equivalent substitute parts are available to support procurement flexibility, supply chain continuity, and design redundancy in applications where component availability or lead times require alternative sourcing.

Substitute Part Grouping Explanation

Substitution of the LHT2W271MELC30 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 270 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: 1.34 A @ 120 Hz and 1.9162 A @ 50 kHz (exact match required)

Mechanical Parameters:

• Package type: Radial, Can - Snap-In (exact match required)
• Mounting type: Through Hole (exact match required)
• Lead spacing: 0.394" (10.00 mm) (exact match required)
• Physical dimensions: 1.378" Dia × 1.280" Height (exact match required)

Compliance Parameters:

• RoHS3 compliance status
• ECCN and HTSUS classifications

Substitute parts must satisfy all electrical, mechanical, and compliance parameters without deviation. The EGXA451VSN271MA30L from Chemi-Con meets these criteria as a parametric equivalent.
