SLPX561M160C3P3 Equivalent & Substitute Parts

Part Overview

The SLPX561M160C3P3 is a 560 µF, 160 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in a radial, can snap-in package. This component is rated for general-purpose applications with an operating temperature range of -40°C to 85°C and a lifetime specification of 3000 hours at 85°C. The part is Active in product status and ROHS3 compliant.

Equivalent and substitute parts are identified when design requirements permit tolerance in specific electrical or thermal parameters while maintaining core functional compatibility. Substitutes are necessary when the primary part becomes unavailable, when thermal performance upgrades are required, or when voltage margin improvements are needed for circuit reliability.

Substitute Part Grouping Explanation

Substitution logic for the SLPX561M160C3P3 is based on the following criteria:

Direct Electrical Compatibility: All substitute parts maintain 560 µF capacitance and ±20% tolerance. Voltage ratings must equal or exceed 160 V to ensure safe operation within the original circuit design margin.

Mechanical Compatibility: All substitutes retain the radial, can snap-in package with identical lead spacing (10.00mm), diameter (25.00mm), and maximum seated height (30.00mm). Through-hole mounting type is preserved across all alternatives.

Thermal Performance: The original part specifies 3000 hours at 85°C. Substitute parts may offer extended lifetime at higher temperatures (105°C) or reduced lifetime at the same temperature, depending on series and manufacturer.

Polarization and Compliance: All substitutes maintain polar configuration and ROHS3 compliance status.

Key Differentiators for Selection:

• Voltage rating (160 V, 180 V, or 200 V)
• Manufacturer (Cornell Dubilier Electronics vs. Nichicon)
• Series designation (SLPX, LPX, LGU, LGW)
• Lifetime specification at rated temperature
• ESR and ripple current ratings

Parameter Comparison

Engineering Selection Recommendations

Same Voltage, Same Manufacturer (CDE LPX561M160C3P3): This part maintains identical electrical specifications and mechanical form factor. The primary difference is reduced lifetime (1000 hours at 85°C versus 3000 hours). Selection is appropriate for applications where the original 3000-hour specification is not required and cost optimization is a priority. Product status is Active and ROHS3 compliant.

Same Voltage, Upgraded Manufacturer (Nichicon LGU2C561MELA): This Nichicon part matches the 160 V rating and 560 µF capacitance while extending operating temperature to 105°C and maintaining 3000-hour lifetime at the higher temperature. Mechanical compatibility is preserved. Selection is appropriate when thermal margin improvement is required without changing voltage rating. Product status is Active and ROHS3 compliant.

Elevated Voltage, Nichicon LGU Series (LGU2D561MELA or LGU2Z561MELA): These parts provide voltage ratings of 200 V (LGU2D561MELA) or 180 V (LGU2Z561MELA) while maintaining 560 µF capacitance and 3000-hour lifetime at 105°C. Mechanical dimensions are identical. Selection is appropriate when circuit design permits higher voltage rating for increased safety margin. Both parts are Active and ROHS3 compliant.

Elevated Voltage, Nichicon LGW Series (LGW2D561MELA30): This part provides 200 V rating with enhanced ripple current capability (2.3 A @ 120 Hz and 3.45 A @ 50 kHz compared to 1.67 A and 2.505 A in LGU series). Mechanical compatibility is maintained. Selection is appropriate for high-ripple-current applications requiring voltage margin. Product status is Active and ROHS3 compliant.

Frequently Asked Questions (FAQ)

Q: Can LPX561M160C3P3 be used as a direct replacement for SLPX561M160C3P3?

A: LPX561M160C3P3 is mechanically and electrically compatible with identical voltage, capacitance, tolerance, and package specifications. The difference is lifetime rating: 1000 hours at 85°C versus 3000 hours. Substitution is valid only if the application does not require the extended 3000-hour lifetime specification.

Q: What is the advantage of Nichicon LGU2C561MELA over the original SLPX561M160C3P3?

A: LGU2C561MELA extends the operating temperature range to 105°C and maintains 3000-hour lifetime at this higher temperature, compared to the original 85°C maximum. All mechanical and electrical parameters remain compatible. This upgrade is beneficial for applications in elevated ambient temperature environments.

Q: Can I use LGU2D561MELA (200 V) in place of SLPX561M160C3P3 (160 V)?

A: Yes. LGU2D561MELA is mechanically identical and provides a higher voltage rating (200 V), which is compatible with circuits designed for 160 V operation. The higher voltage rating provides additional safety margin. All other parameters including capacitance, tolerance, and package are matched.

Q: What is the difference between LGU2D561MELA and LGW2D561MELA30?

A: Both parts are 560 µF, 200 V, Nichicon-manufactured capacitors with identical mechanical dimensions and 3000-hour lifetime at 105°C. The primary difference is ripple current capability: LGW2D561MELA30 provides higher ripple current ratings (2.3 A @ 120 Hz and 3.45 A @ 50 kHz) compared to LGU2D561MELA (1.67 A @ 120 Hz and 2.505 A @ 50 kHz). Selection depends on circuit ripple current requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed maintain ROHS3 compliance status, ensuring compatibility with regulatory requirements.

Q: Do all substitutes have the same lead spacing and mounting footprint?

A: Yes. All substitute parts maintain 10.00 mm lead spacing, 25.00 mm diameter, and 30.00 mm maximum seated height. Through-hole mounting type is consistent across all alternatives, ensuring PCB compatibility without layout modification.

Q: Can I substitute based on ESR (Equivalent Series Resistance) values?

A: The original SLPX561M160C3P3 specifies 355 mOhm ESR at 120 Hz. Nichicon substitute parts do not provide ESR specifications in the available data. ESR-critical applications should verify Nichicon specifications through the manufacturer before substitution.

Q: What is the inventory status for each substitute part?

A: Current inventory levels are: SLPX561M160C3P3 (877 pcs), LPX561M160C3P3 (1174 pcs), LGU2C561MELA (1037 pcs), LGU2D561MELA (1954 pcs), LGU2Z561MELA (770 pcs), and LGW2D561MELA30 (1010 pcs). Inventory status is subject to change and should be verified at time of procurement.
