Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LLS2W820MELY is determined by the following criteria:

Primary Matching Parameters:

• Capacitance value: 82 µF (exact match required)
• Voltage rating: 450 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package configuration: Radial, Can - Snap-In (exact match required)
• Lead spacing: 0.394" (10.00 mm) (exact match required)
• Mounting type: Through Hole (exact match required)

Secondary Compatibility Factors:

• Operating temperature range and lifetime ratings may vary within acceptable industrial standards
• Physical dimensions (diameter and height) may differ while maintaining the same lead spacing and package footprint
• Ripple current ratings and ESR specifications may vary based on manufacturer design
• RoHS and REACH compliance status must be maintained

The identified substitute parts meet all primary matching parameters and maintain compatibility with the original circuit design and PCB layout.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain Active product status and full compliance with ROHS3 and REACH regulations. Selection among equivalent parts should be based on the following factors:

LGU2W820MELY (Nichicon): This substitute offers an extended operating temperature range (-25°C to 105°C) compared to the main part, providing enhanced thermal performance for applications requiring operation at elevated ambient temperatures. The part maintains identical lead spacing and package footprint while accommodating higher temperature environments.

LLS2W820MELZ (Nichicon): This substitute is from the same LLS series as the main part and provides identical electrical performance characteristics. Physical dimensions differ (0.866" diameter, 0.984" height), requiring verification of available PCB space. This part offers higher inventory availability.

380LX820M450H022 (Cornell Dubilier Electronics): This substitute from an alternative manufacturer provides equivalent electrical specifications with documented ESR of 2 Ohm @ 120 Hz. Physical dimensions differ (0.866" diameter, 1.260" height), requiring PCB layout verification. This part offers the highest inventory availability among substitutes.

All substitute parts are suitable for direct replacement in applications where the original LLS2W820MELY is specified, provided that physical dimensions are accommodated within the circuit board design.

Frequently Asked Questions (FAQ)

Q: Can LGU2W820MELY be used as a direct replacement for LLS2W820MELY?

A: Yes. Both parts share identical capacitance (82 µF), voltage rating (450 V), tolerance (±20%), lead spacing (10.00 mm), and package type (Radial, Can - Snap-In). The LGU2W820MELY offers extended temperature operation to 105°C versus 85°C for the LLS2W820MELY. Physical dimensions are identical, ensuring PCB compatibility.

Q: What are the physical dimension differences between substitute parts?

A: The main part LLS2W820MELY and LGU2W820MELY both measure 0.787" diameter × 1.378" height. The LLS2W820MELZ and 380LX820M450H022 both measure 0.866" diameter but differ in height (0.984" and 1.260" respectively). Lead spacing remains constant at 0.394" (10.00 mm) across all parts.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts carry ROHS3 Compliant status and REACH Unaffected designation, maintaining regulatory compliance with the original part specification.

Q: How do ripple current ratings compare across substitute parts?

A: The main part LLS2W820MELY and substitute LLS2W820MELZ both support 800 mA @ 120 Hz and 1.144 A @ 50 kHz. The LGU2W820MELY supports 640 mA @ 120 Hz and 915.2 mA @ 50 kHz. The 380LX820M450H022 supports 830 mA @ 120 Hz and 1.16 A @ 20 kHz. Selection should be based on circuit ripple current requirements.

Q: Can substitute parts from different manufacturers be intermixed in the same application?

A: Yes, provided all electrical parameters (capacitance, voltage, tolerance) and mechanical specifications (lead spacing, package type, mounting) match the circuit requirements. All identified substitutes meet these criteria and maintain equivalent regulatory compliance.
