Key Parameters

Substitute Part Grouping Explanation

Substitution for the ECO-S1CP393DA is determined by strict equivalence across the following parameters: capacitance value (39000 µF), voltage rating (16 V), tolerance (±20%), package configuration (radial, can snap-in), lead spacing (10.00mm), case diameter (1.181"), mounting type (through hole), and thermal rating (3000 Hrs @ 85°C). All identified substitutes maintain these core electrical and mechanical specifications, ensuring direct functional compatibility in the original application circuit.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active products with current manufacturing status, providing supply continuity for the obsolete ECO-S1CP393DA. SLPX393M016E4P3 and 380LX393M016K452 from Cornell Dubilier Electronics, and LLS1C393MELB from Nichicon all meet ROHS3 compliance requirements. The SLPX393M016E4P3 offers the lowest ESR at 17 mOhm and a reduced height of 45.00 mm, which may provide performance advantages in ripple current applications. The 380LX393M016K452 maintains identical height and ESR characteristics closest to the original part at 22 mOhm. The LLS1C393MELB from Nichicon provides an alternative manufacturer source with equivalent mechanical and electrical specifications. Selection should be based on supply availability, compliance requirements for the end application, and any specific ESR or height constraints in the circuit design.

Frequently Asked Questions (FAQ)

Q: Can SLPX393M016E4P3 be used as a direct replacement for ECO-S1CP393DA? A: Yes. Both parts share identical capacitance (39000 µF), voltage rating (16 V), tolerance (±20%), lead spacing (10.00 mm), case diameter (30.00 mm), and thermal rating (3000 Hrs @ 85°C). The SLPX393M016E4P3 has a reduced height of 45.00 mm compared to 47.00 mm, which is compatible with standard PCB layouts designed for snap-in radial capacitors.

Q: What is the difference between the three substitute parts? A: All three substitutes maintain electrical and mechanical equivalence. Primary differences are ESR values (SLPX393M016E4P3 at 17 mOhm is lowest; 380LX393M016K452 at 22 mOhm is closest to original; LLS1C393MELB ESR not specified) and height (SLPX393M016E4P3 at 45.00 mm versus 47.00 mm for the others). Manufacturer sourcing differs: Cornell Dubilier Electronics supplies two variants, Nichicon supplies one.

Q: Are all substitutes RoHS compliant? A: Yes. SLPX393M016E4P3, 380LX393M016K452, and LLS1C393MELB are all ROHS3 compliant, whereas the original ECO-S1CP393DA is RoHS non-compliant.

Q: Does the 2 mm height difference of SLPX393M016E4P3 affect compatibility? A: No. The 45.00 mm height of SLPX393M016E4P3 is within standard mechanical tolerances for snap-in radial capacitor installations. PCB layouts designed for 47.00 mm height accommodate this variation.

Q: Which substitute has the best ripple current performance? A: 380LX393M016K452 provides the highest ripple current at high frequency (8 A @ 20 kHz) and low frequency (6.95 A @ 120 Hz), making it suitable for applications requiring maximum ripple current handling.
