ECO-S2AP392DA Equivalent & Substitute Parts

Part Overview

The ECO-S2AP392DA is a 3900 µF, 100 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by Panasonic Electronic Components. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations. The part operates across a temperature range of -40°C to 85°C with a rated lifetime of 3000 hours at 85°C, serving general-purpose applications requiring high-capacitance energy storage.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following parameters:

Capacitance value: 3900 µF (exact match required)
Voltage rating: 100 V or higher (equal or greater)
Tolerance: ±20% (matching specification)
Package type: Radial, Can - Snap-In (mechanical compatibility)
Lead spacing: 0.394" (10.00 mm) (PCB layout compatibility)
Mounting type: Through Hole (assembly process compatibility)
Operating temperature range: -40°C minimum, 85°C minimum upper limit
Polarization: Polar (electrical compatibility)

Substitute parts are grouped into two categories: direct equivalents (matching all critical parameters including physical dimensions) and similar parts (matching electrical parameters with acceptable dimensional variations within the snap-in package envelope).

Engineering Selection Recommendations

Direct Equivalents (Identical Physical Dimensions)

SLPX392M100E4P3 is the primary direct equivalent. It matches the original part's case diameter (30.00 mm) and height (45.00 mm) exactly, with identical lead spacing and snap-in package configuration. The part features lower ESR (68 mOhm versus 77 mOhm), improved electrical performance, and active product status with RoHS3 compliance.

Mechanical Compatibility Considerations

Parts with dimensional variations require PCB layout verification:

380LX392M100K452: Height increased to 47.00 mm (2 mm taller). Verify clearance above component.
SLPX392M100H5P3: Case diameter increased to 35.00 mm, height reduced to 35.00 mm. Verify PCB footprint accommodation.
100MXG3900MEFCSN30X45: Height 47.00 mm. Verify vertical clearance.
380LX392M100A032: Case diameter 35.00 mm, height 37.00 mm. Verify footprint fit.

Voltage Derating Consideration

80USG3900MEFCSN30X35 and 80VXG3900MEFC30X45 are rated at 80 V. These parts are suitable only for applications where the circuit operates at 80 V or below. Do not use in 100 V circuits.

Compliance and Availability

All active substitute parts carry RoHS3 compliance and REACH unaffected status. SLPX392M100E4P3 and SLPX392M100H5P3 offer the lowest ESR values (68 mOhm), beneficial for high-ripple-current applications. Rubycon parts (100MXG3900MEFCSN30X45, 80VXG3900MEFC30X45) provide extended lifetime ratings at elevated temperatures (5000 hours at 105°C for VXG series).

Frequently Asked Questions (FAQ)

Q: Can SLPX392M100H5P3 be used as a direct replacement for ECO-S2AP392DA?

A: SLPX392M100H5P3 is electrically equivalent but has different physical dimensions. The case diameter is 35.00 mm (versus 30.00 mm) and height is 35.00 mm (versus 45.00 mm). PCB layout must accommodate the larger diameter. Lead spacing remains compatible at 0.394" (10.00 mm).

Q: What is the difference between 380LX392M100K452 and 380LX392M100A032?

A: Both are Cornell Dubilier 380LX series parts with identical electrical specifications (3900 µF, 100 V, 80 mOhm ESR). The primary difference is physical size: 380LX392M100K452 is 30.00 mm diameter × 47.00 mm height, while 380LX392M100A032 is 35.00 mm diameter × 37.00 mm height. Select based on available PCB space.

Q: Can 80USG3900MEFCSN30X35 replace the original part in a 100 V circuit?

A: No. 80USG3900MEFCSN30X35 is rated at 80 V maximum. Using it in a 100 V circuit exceeds its voltage rating and will cause premature failure. Use only in circuits operating at 80 V or below.

Q: Which substitute offers the best performance for high-ripple-current applications?

A: SLPX392M100E4P3 and SLPX392M100H5P3 both feature 68 mOhm ESR at 120 Hz, the lowest among available substitutes. Lower ESR reduces heat generation under ripple current stress. SLPX392M100E4P3 maintains the original case diameter (30.00 mm), making it the preferred choice if PCB space is constrained.

Q: Are all substitute parts RoHS compliant?

A: All active substitute parts listed are RoHS3 compliant. The original ECO-S2AP392DA (obsolete) does not carry RoHS certification in the provided data.

Q: What is the significance of the 3000 Hrs @ 85°C lifetime specification?

A: This indicates the capacitor's expected operational life under rated voltage and temperature conditions. All 100 V rated substitutes maintain this specification. Rubycon VXG series (80VXG3900MEFC30X45) extends to 5000 hours at 105°C, offering longer service life in elevated-temperature environments.

Q: Can parts with different case diameters be used interchangeably on the same PCB?

A: No. Case diameter determines the physical footprint on the PCB. Parts with 30.00 mm diameter fit the original footprint; parts with 35.00 mm diameter require a larger pad pattern. Verify PCB layout compatibility before substitution.
