Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LLS2D221MELY is determined by the following critical parameters:

• Capacitance Value: Must be 220 µF (exact match required)
• Tolerance: Must be ±20% (exact match required)
• Package Type: Must be Radial, Can - Snap-In (exact match required)
• Lead Spacing: Must be 0.394" (10.00mm) (exact match required)
• Mounting Type: Must be Through Hole (exact match required)
• Series: Must be LLS (exact match required)
• Voltage Rating: May be equal to or higher than 200 V (uprating permitted)
• Operating Temperature Range: Must support -40°C ~ 85°C minimum
• Lifetime: Must meet or exceed 3000 Hrs @ 85°C

The substitute part LLS2E221MELZ meets all mandatory parameters with an uprated voltage specification of 250 V, which is permissible in applications designed for 200 V operation.

Parameter Comparison

Engineering Selection Recommendations

Both the LLS2D221MELY and LLS2E221MELZ are Active status components manufactured by Nichicon and certified ROHS3 compliant. The LLS2E221MELZ provides a higher voltage rating (250 V versus 200 V) while maintaining identical capacitance, tolerance, lead spacing, and mounting configuration. Selection between these parts depends on circuit voltage requirements and available board space. The LLS2E221MELZ has a larger diameter (22.00mm versus 20.00mm), which must be verified against PCB layout constraints. Both parts support the same operating temperature range and thermal lifetime specification.

Frequently Asked Questions (FAQ)

Q: Can LLS2E221MELZ replace LLS2D221MELY in a 200 V circuit?

A: Yes. The LLS2E221MELZ is rated for 250 V, which exceeds the 200 V circuit requirement. Voltage uprating is permissible and does not degrade circuit performance.

Q: Are the lead spacings identical between these parts?

A: Yes. Both parts have 0.394" (10.00mm) lead spacing, ensuring PCB footprint compatibility.

Q: What is the physical size difference?

A: The LLS2D221MELY has a 0.787" (20.00mm) diameter, while the LLS2E221MELZ has a 0.866" (22.00mm) diameter. Both share the same 0.984" (25.00mm) height. Board layout must accommodate the larger diameter of the substitute part.

Q: Do both parts meet the same thermal lifetime specification?

A: Yes. Both parts are rated for 3000 Hrs @ 85°C and support the operating temperature range of -40°C ~ 85°C.

Q: Are there compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99.

Q: What is the ripple current difference?

A: The LLS2E221MELZ has slightly higher ripple current ratings: 1.24 A @ 120 Hz (versus 1.19 A) and 1.86 A @ 50 kHz (versus 1.785 A). This reflects the higher voltage rating and larger physical size.
