Engineering Selection Recommendations

Direct Equivalent Substitution: The 380LQ561M250J022 (Cornell Dubilier Electronics, 380LQ series) functions as a direct equivalent with identical electrical specifications and extended operational lifetime (2000 Hrs @ 85°C versus 1000 Hrs). Physical dimensions differ slightly (25 mm diameter, 32 mm height versus 35 mm diameter, 25 mm height), requiring verification of available PCB space. This part maintains full RoHS3 compliance and REACH unaffected status.

Enhanced Performance Substitution: The SLPX561M250C5P3 (Cornell Dubilier Electronics, SLPX series) provides further extended lifetime (3000 Hrs @ 85°C) with marginally improved ripple current handling (2.35 A @ 120 Hz). Physical dimensions are 25 mm diameter and 35 mm height. This part is suitable for applications requiring extended service intervals within the 85°C thermal envelope.

Cross-Manufacturer Substitution: The LLS2E561MELB (Nichicon, LLS series) offers equivalent electrical performance with 3000 Hrs @ 85°C lifetime and maintains identical lead spacing and mounting type. Physical dimensions are 30 mm diameter and 25 mm height. ESR specification is not provided in technical documentation. This part is suitable for applications where cross-manufacturer sourcing is acceptable.

Thermal Upgrade Substitution: The LGU2E561MELC (Nichicon, LGU series) represents a thermal upgrade option with extended operating temperature range (-40°C to 105°C) and 3000 Hrs @ 105°C lifetime rating. Physical dimensions match the main part (35 mm diameter, 25 mm height). This part is specified for applications requiring enhanced thermal performance or operation in elevated temperature environments. Ripple current ratings are lower (1.8 A @ 120 Hz), requiring circuit analysis for compatibility.

Selection Criteria:

All substitute parts maintain Active product status
All substitute parts are RoHS3 compliant and REACH unaffected
Physical envelope constraints must be verified against PCB layout
Thermal requirements determine selection between 85°C and 105°C rated options
Extended lifetime options (2000 Hrs or 3000 Hrs) are suitable for reliability-critical applications

Frequently Asked Questions (FAQ)

Q: Can the LPX561M250H1P3 be replaced with the 380LQ561M250J022?

A: Yes. Both parts share identical capacitance (560 µF), voltage rating (250 V), tolerance (±20%), ESR (355 mOhm @ 120Hz), lead spacing (10 mm), and RoHS3 compliance. The 380LQ561M250J022 provides extended lifetime (2000 Hrs @ 85°C). Physical dimensions differ: 380LQ is 25 mm diameter × 32 mm height versus LPX at 35 mm diameter × 25 mm height. Verify available PCB space before substitution.

Q: What is the difference between the SLPX561M250C5P3 and LLS2E561MELB?

A: Both parts provide 3000 Hrs @ 85°C lifetime and identical electrical core parameters. The SLPX is manufactured by Cornell Dubilier Electronics (CDE) with 25 mm diameter × 35 mm height.

A: Yes. The LGU2E561MELC extends the operating temperature range to -40°C to 105°C with 3000 Hrs @ 105°C lifetime rating. This part is specified for applications requiring thermal performance beyond the standard 85°C envelope. Physical dimensions match the main part (35 mm diameter × 25 mm height). Note that ripple current rating is lower (1.8 A @ 120 Hz) compared to the main part (2.1 A @ 120 Hz), requiring circuit verification.

Q: Do all substitute parts maintain the same lead spacing?

A: Yes. All substitute parts maintain 10.00 mm lead spacing, ensuring PCB footprint compatibility. Physical diameter and height vary across substitute options, requiring verification of available vertical and horizontal space in the component mounting area.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts (380LQ561M250J022, SLPX561M250C5P3, LLS2E561MELB, and LGU2E561MELC) are RoHS3 compliant and REACH unaffected, maintaining regulatory compliance with the main part.

Q: Which substitute part offers the longest operational lifetime?

A: The SLPX561M250C5P3, LLS2E561MELB, and LGU2E561MELC all provide 3000 Hrs operational lifetime. The SLPX and LLS are rated at 85°C, while the LGU is rated at 105°C. Selection depends on thermal operating conditions and manufacturer preference.

Q: Can the LPX561M250H1P3 be used in applications requiring 105°C operation?

A: No. The LPX561M250H1P3 is rated for -40°C to 85°C operation. For applications requiring 105°C thermal performance, the LGU2E561MELC (Nichicon, LGU series) is the appropriate substitute with -40°C to 105°C operating range and 3000 Hrs @ 105°C lifetime.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: capacitance (560 µF exact), voltage rating (250 V exact), tolerance (±20% exact), ESR (355 mOhm @ 120Hz exact), lead spacing (10 mm exact), package type (Radial, Can - Snap-In exact), mounting type (Through Hole exact), and RoHS3 compliance (exact). Physical dimensions (diameter and height) may vary within mechanical envelope constraints. Lifetime and operating temperature range may exceed minimum specifications.
