Engineering Selection Recommendations

LLS2Z102MELZ (Nichicon): This substitute maintains identical capacitance, tolerance, and package specifications as the main part. The voltage rating is increased to 180 V, providing higher voltage margin in the application circuit. Physical dimensions differ slightly in height (50.00mm vs. 45.00mm), requiring verification of available board space. Ripple current performance is marginally improved. All compliance certifications match the main part.

SLPX102M160E3P3 (Cornell Dubilier Electronics): This substitute maintains identical capacitance, tolerance, voltage rating, and package specifications as the main part. Physical dimensions differ significantly in both diameter (30.00mm vs. 22.00mm) and height (30.00mm vs. 45.00mm), requiring mechanical compatibility assessment for the target application. ESR is specified at 199mOhm @ 120Hz. All compliance certifications match the main part.

Selection between substitutes depends on mechanical space constraints and ripple current requirements specific to the application circuit.

Frequently Asked Questions (FAQ)

Q: Can LLS2Z102MELZ be used as a direct replacement for LLS2C102MELZ?

A: LLS2Z102MELZ qualifies as a functional substitute based on matching capacitance, tolerance, package type, and mounting specifications. The higher voltage rating (180 V vs. 160 V) is acceptable for applications designed for 160 V operation. Physical height difference (50.00mm vs. 45.00mm) must be verified against available board space before implementation.

Q: What are the mechanical constraints when substituting SLPX102M160E3P3?

A: SLPX102M160E3P3 has significantly different physical dimensions: diameter of 30.00mm (vs. 22.00mm) and height of 30.00mm (vs. 45.00mm). Board layout and component spacing must accommodate these dimensional changes. Lead spacing remains compatible at 0.394" (10.00mm).

Q: Are all substitute parts RoHS compliant?

A: Yes. LLS2Z102MELZ, SLPX102M160E3P3, and the main part LLS2C102MELZ are all ROHS3 Compliant.

Q: Do substitute parts maintain the same operating temperature range?

A: Yes. All parts operate within -40°C ~ 85°C and maintain 3000 Hrs @ 85°C lifetime specification.

Q: Which substitute offers the best ripple current performance?

A: LLS2Z102MELZ provides the highest ripple current at high frequency (4.65 A @ 50 kHz). SLPX102M160E3P3 provides 4.35 A @ 20 kHz. Selection depends on the specific frequency characteristics of the application circuit.
