Substitute Part Grouping Explanation

Substitution of the Nichicon LLS2Z561MELY is permissible with the Nichicon LLS2D561MELY based on the following criteria:

Matching Parameters (Substitution Basis):

• Capacitance: 560 µF (identical)
• Tolerance: ±20% (identical)
• Lifetime @ Temperature: 3000 Hrs @ 85°C (identical)
• Operating Temperature Range: -40°C ~ 85°C (identical)
• Polarization: Polar (identical)
• Lead Spacing: 0.394" (10.00mm) (identical)
• Size / Dimension: 0.787" Dia (20.00mm) (identical)
• Height - Seated (Max): 1.575" (40.00mm) (identical)
• Mounting Type: Through Hole (identical)
• Package / Case: Radial, Can - Snap-In (identical)
• RoHS Status: ROHS3 Compliant (identical)

Differing Parameter:

• Voltage - Rated: LLS2Z561MELY is 180 V; LLS2D561MELY is 200 V

The substitute part LLS2D561MELY provides a higher voltage rating (200 V vs. 180 V) while maintaining all other electrical and mechanical specifications. This represents an upgrade path for applications requiring additional voltage margin.

Parameter Comparison

Engineering Selection Recommendations

Both the LLS2Z561MELY and LLS2D561MELY are Active status components with ROHS3 compliance and REACH unaffected status. Selection between these parts depends on circuit voltage requirements:

• LLS2Z561MELY (180 V): Select when the application circuit operates at or below 180 V and component cost optimization is prioritized.
• LLS2D561MELY (200 V): Select when the application circuit requires voltage margin above 180 V or when operating conditions demand higher voltage headroom. The 200 V rating provides additional safety margin in designs with voltage transients or tolerance stack-up considerations.

Both parts maintain identical physical dimensions, lead spacing, and mounting configuration, ensuring direct PCB compatibility. Ripple current specifications are equivalent across both frequency ranges (120 Hz and 50 kHz), confirming functional interchangeability within their respective voltage ratings.

Frequently Asked Questions (FAQ)

Q: Can LLS2D561MELY replace LLS2Z561MELY in any application?

A: Yes, the LLS2D561MELY can replace the LLS2Z561MELY in any application designed for 180 V operation. The higher 200 V rating of the substitute part is backward compatible with lower voltage designs. Physical dimensions and electrical characteristics remain identical.

Q: What is the primary difference between these two parts?

A: The sole difference is the voltage rating: LLS2Z561MELY is rated 180 V, while LLS2D561MELY is rated 200 V. All other parameters—capacitance, tolerance, temperature range, ripple current, and physical dimensions—are identical.

Q: Are these parts pin-compatible?

A: Yes. Both parts feature identical lead spacing (0.394" / 10.00mm), identical physical dimensions (0.787" diameter, 1.575" height), and the same radial, can snap-in package configuration. They are direct PCB replacements.

Q: Do both parts meet the same compliance standards?

A: Yes. Both LLS2Z561MELY and LLS2D561MELY are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Q: What is the temperature performance of these capacitors?

A: Both parts are rated for 3000 hours of operation at 85°C and support an operating temperature range of -40°C to 85°C. Thermal performance is identical between the two models.
