Substitute Part Grouping Explanation

Substitution eligibility for the LLS2V102MELC is determined by the following critical parameters:

• Capacitance Value: 1000 µF (exact match required)
• Voltage Rating: 350 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package Configuration: Radial, Can - Snap-In (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lead Spacing: 0.394" (10.00 mm) (exact match required)
• Diameter: 1.378" (35.00 mm) (exact match required)
• Operating Temperature Range: -25°C to 85°C (exact match required)
• Polarization: Polar (exact match required)

The substitute part ESMQ351VSN102MA50S meets all critical electrical and mechanical parameters, confirming functional equivalence for direct replacement in applications where the LLS2V102MELC is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the LLS2V102MELC and ESMQ351VSN102MA50S are active production parts with full RoHS compliance and REACH unaffected status. The primary distinction between these parts is the rated lifetime at 85°C: the LLS2V102MELC provides 3000 hours while the ESMQ351VSN102MA50S provides 2000 hours. Selection should be based on application lifetime requirements and thermal operating conditions. Both parts are suitable for general-purpose applications and are mechanically and electrically interchangeable within the specified operating parameters. The 2 mm height difference (52 mm versus 50 mm) must be verified against PCB layout constraints and enclosure clearances.

Frequently Asked Questions (FAQ)

Q: Can ESMQ351VSN102MA50S replace LLS2V102MELC in all applications?

A: Yes, provided that the application does not require the extended 3000-hour lifetime rating at 85°C. The ESMQ351VSN102MA50S is rated for 2000 hours at 85°C. Both parts are electrically and mechanically equivalent for all other parameters.

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

A: The LLS2V102MELC has a seated height of 2.047" (52.00 mm) while the ESMQ351VSN102MA50S has a seated height of 1.969" (50.00 mm). This 2 mm difference must be evaluated against PCB layout, component clearances, and enclosure dimensions to ensure mechanical fit.

Q: Are both parts RoHS compliant?

A: Yes. The LLS2V102MELC is ROHS3 compliant and the ESMQ351VSN102MA50S is RoHS compliant. Both meet regulatory requirements for hazardous substance restrictions.

Q: What are the ripple current specifications for these capacitors?

A: The LLS2V102MELC is rated for 3.6 A at 120 Hz and 5.148 A at 50 kHz. The ESMQ351VSN102MA50S is rated for 4.64 A at 120 Hz and 5.062 A at 50 kHz. Both specifications are suitable for general-purpose applications within their respective thermal and voltage operating ranges.

Q: Can these capacitors be used interchangeably on the same PCB?

A: Yes, provided that the 2 mm height difference does not create mechanical interference with adjacent components or enclosure constraints. Lead spacing, diameter, and mounting type are identical, ensuring direct PCB compatibility.
