Substitute Part Grouping Explanation

Substitution eligibility for the LLS2W820MELZ is determined by strict equivalence across the following critical parameters:

• Capacitance value: 82 µF (exact match required)
• Voltage rating: 450 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Package type: Radial, Can - Snap-In (exact match required)
• Mounting type: Through Hole (exact match required)
• Lead spacing: 0.394" (10.00mm) (exact match required)
• Diameter: 0.866" (22.00mm) (exact match required)
• Lifetime specification: 3000 Hrs @ 85°C (exact match required)
• Operating temperature range: -25°C ~ 85°C (exact match required)
• Regulatory compliance: ROHS3 Compliant (exact match required)

The substitute part 380LX820M450H022 meets all critical electrical and mechanical parameters. Variations in height, ESR specifications, and ripple current ratings at specific frequencies do not disqualify substitution when the core functional parameters align.

Parameter Comparison

Engineering Selection Recommendations

The 380LX820M450H022 from Cornell Dubilier Electronics qualifies as a direct substitute for the LLS2W820MELZ based on electrical and mechanical equivalence. Both components are ROHS3 compliant, REACH unaffected, and classified under the same HTSUS code, confirming regulatory and trade compliance alignment.

The primary design consideration is the height difference: the CDE part measures 1.260" (32.00mm) seated height compared to 0.984" (25.00mm) for the Nichicon part. This 7mm increase must be evaluated against available PCB clearance and enclosure constraints. The identical lead spacing (10.00mm) and diameter (22.00mm) ensure mechanical compatibility with snap-in mounting hardware.

Both parts maintain equivalent ripple current performance within their specified frequency ranges and support the same thermal and operational envelope. Selection between these parts should be based on physical space availability, supply chain status, and cost considerations.

Frequently Asked Questions (FAQ)

Q: Can the 380LX820M450H022 be used as a direct replacement for the LLS2W820MELZ?

A: Yes, the 380LX820M450H022 meets all critical electrical specifications: 82 µF capacitance, 450 V rating, ±20% tolerance, 3000 Hrs @ 85°C lifetime, and identical operating temperature range. Both use the same radial snap-in package with 10.00mm lead spacing and 22.00mm diameter. Physical space must accommodate the 32.00mm height of the CDE part versus 25.00mm for the Nichicon part.

Q: What is the significance of the height difference between these parts?

A: The 380LX820M450H022 is 7mm taller when seated. This difference is critical for applications with limited vertical clearance. PCB layout and enclosure design must be evaluated to confirm the taller component fits within available space. The identical lead spacing and diameter do not change mounting compatibility.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the LLS2W820MELZ and 380LX820M450H022 are ROHS3 compliant and REACH unaffected. Both are classified under HTSUS code 8532.22.0040 and carry EAR99 export classification.

Q: How do the ripple current ratings compare?

A: The LLS2W820MELZ specifies 800 mA @ 120 Hz and 1.144 A @ 50 kHz. The 380LX820M450H022 specifies 830 mA @ 120 Hz and 1.16 A @ 20 kHz. Both parts support equivalent ripple current performance within their respective frequency specifications. The frequency difference reflects manufacturer test methodology and does not indicate functional incompatibility.

Q: What does the ESR specification mean for the CDE part?

A: The 380LX820M450H022 specifies 2 Ohm ESR @ 120 Hz. The LLS2W820MELZ does not provide an ESR specification in the available data. ESR affects heat dissipation and filtering performance at specific frequencies. Applications sensitive to ESR characteristics should confirm the 2 Ohm specification meets circuit requirements.

Q: Are there any inventory or availability differences?

A: The LLS2W820MELZ has 1349 units in stock. The 380LX820M450H022 has 2172 units in stock. Both are active production parts with established supply availability.
