Engineering Selection Recommendations

Electrical Compatibility: All substitute parts maintain identical capacitance (560 µF), tolerance (±20%), and rated voltage (250 V) specifications. All components are polar aluminum electrolytic capacitors with matching operating temperature ranges (-40°C to 105°C) and lead spacing (10.00 mm). Electrical substitution is valid across all identified parts.

Regulatory Compliance: All substitute parts carry ROHS3 Compliant and REACH Unaffected certifications, matching the regulatory status of the LP561M250H3P3. No compliance barriers exist for cross-substitution.

Physical Fit Considerations: The LP561M250H3P3, 381LX561M250A012, and LGU2E561MELC share identical diameter (35.00 mm) and similar height profiles, making them direct mechanical substitutes in space-constrained applications. The 381LQ561M250J032 features a smaller diameter (25.00 mm) but greater height (37.00 mm), requiring verification of available board space. The 381LR561M250K022 presents intermediate dimensions (30.00 mm diameter, 32.00 mm height).

Performance Characteristics: The 381LR561M250K022 offers the lowest ESR (266 mOhm @ 120Hz) and highest ripple current capacity (2.14 A @ 120 Hz, 3.05 A @ 20 kHz), along with extended lifetime (3000 hours @ 105°C). The LGU2E561MELC provides equivalent lifetime (3000 hours @ 105°C) with ripple current performance (1.8 A @ 120 Hz) matching the original LP561M250H3P3. The 381LQ561M250J032 offers improved ESR (296 mOhm) and doubled lifetime (2000 hours) in a compact form factor.

Product Status: All substitute parts maintain Active product status, ensuring continued availability and manufacturing support.
