Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LLS2C561MELZ is determined by strict alignment with the following critical parameters:

• Capacitance value: 560 µF (exact match required)
• Voltage rating: 160 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package type: Radial, Can - Snap-In (exact match required)
• Mounting type: Through Hole (exact match required)
• Lead spacing: 0.394" (10.00mm) (exact match required)
• Operating temperature range: -40°C ~ 85°C (minimum requirement)
• Polarization: Polar (exact match required)
• RoHS compliance: ROHS3 Compliant (minimum requirement)

The LPX561M160C3P3 from Cornell Dubilier Electronics meets all mandatory substitution criteria. Physical dimensions vary within acceptable mechanical tolerances for snap-in mounting applications. Electrical performance characteristics including ESR, ripple current ratings, and lifetime specifications differ but remain within functional parameters for general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

Both the LLS2C561MELZ and LPX561M160C3P3 maintain Active product status and satisfy ROHS3 compliance and REACH unaffected requirements. Selection between these parts should be based on:

• PCB layout constraints: The LLS2C561MELZ features a smaller diameter (22.00mm) compared to the LPX561M160C3P3 (25.00mm). Verify available board space accommodates the selected substitute.
• Inventory availability: The LPX561M160C3P3 currently maintains higher stock levels (1174 units) versus the LLS2C561MELZ (982 units).
• Electrical performance requirements: Both parts operate within the specified temperature range and voltage rating. Differences in ESR and ripple current ratings are documented but do not affect general-purpose application suitability.

Frequently Asked Questions (FAQ)

Q: Can the LPX561M160C3P3 be used as a direct replacement for the LLS2C561MELZ?

A: Yes. Both parts share identical capacitance (560 µF), voltage rating (160 V), tolerance (±20%), operating temperature range (-40°C ~ 85°C), package type (Radial, Can - Snap-In), mounting type (Through Hole), and lead spacing (0.394" / 10.00mm). Physical diameter differs by 3.00mm, requiring PCB layout verification.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer origin, series designation, physical diameter, ESR characteristics, ripple current ratings, and lifetime specifications. All differences remain within acceptable parameters for general-purpose applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the LLS2C561MELZ and LPX561M160C3P3 are ROHS3 Compliant and REACH Unaffected.

Q: Does the larger diameter of the LPX561M160C3P3 affect compatibility?

A: The 3.00mm diameter increase (from 22.00mm to 25.00mm) does not affect electrical compatibility. Physical board space must be verified to accommodate the larger can diameter. Lead spacing and height remain identical.

Q: Can these parts be used interchangeably in existing designs?

A: Electrical interchangeability is confirmed. Mechanical interchangeability requires verification that PCB layout accommodates the dimensional differences, specifically the can diameter variation.
