Engineering Selection Recommendations

Direct Manufacturer Substitutes (Highest Compatibility):

380LX332M080K022 (Cornell Dubilier Electronics) and 80USG3300MEFCSN30X30 (Rubycon) are direct manufacturer equivalents with active product status. Both maintain identical electrical specifications to the ECO-S1KP332DA, including 3000-hour lifetime at 85°C and matching ESR characteristics. Both are ROHS3 compliant. The 380LX series offers 851 units in stock, while the Rubycon USG series provides 969 units in stock.

Parametric Equivalent (Acceptable Alternative):

SLPX332M080E3P3 (Cornell Dubilier Electronics) is a parametric equivalent with active product status and ROHS3 compliance. This part maintains identical capacitance, voltage, tolerance, and lifetime specifications. The ESR is 101 mOhm at 120Hz, which is 16 mOhm higher than the original specification but remains within acceptable operating parameters for general-purpose applications. Height is 1.181" (30.00 mm), matching the original dimension exactly. Inventory availability is 9173 units.

Secondary Alternative (Reduced Lifetime):

B41231C0338M000 (EPCOS - TDK Electronics) is mechanically and electrically compatible with one exception: the rated lifetime is 2000 hours at 85°C, compared to 3000 hours for the original part. This part is ROHS3 compliant and active. Selection of this part is appropriate only when the reduced lifetime specification meets application requirements. Inventory availability is 1271 units.

Mechanical Clearance Consideration:

Three substitute parts (380LX332M080K022, 80USG3300MEFCSN30X30, and B41231C0338M000) have a seated height of 1.260" (32.00 mm), which is 0.079" (2.00 mm) taller than the original ECO-S1KP332DA. Verify available vertical clearance in the target application before selection.

Frequently Asked Questions (FAQ)

Q: Can I use SLPX332M080E3P3 as a direct replacement for ECO-S1KP332DA?

A: Yes. SLPX332M080E3P3 meets all core substitution criteria: identical capacitance (3300 µF), voltage rating (80 V), tolerance (±20%), lead spacing (10.00 mm), case diameter (30.00 mm), and operating temperature range (-40°C to 85°C). The ESR is 101 mOhm versus 85 mOhm in the original, which is an acceptable variation for general-purpose applications. Lifetime is 3000 hours at 85°C, matching the original specification.

Q: What is the difference between direct manufacturer substitutes and parametric equivalents?

A: Direct manufacturer substitutes (380LX332M080K022 and 80USG3300MEFCSN30X30) are functionally identical to the original part with matching ESR and lifetime specifications. Parametric equivalents (SLPX332M080E3P3) meet all critical electrical and mechanical parameters but may have minor variations in secondary characteristics such as ESR. Both categories are electrically and mechanically compatible.

Q: Why is B41231C0338M000 listed if it has a shorter lifetime?

A: B41231C0338M000 is listed as a secondary alternative because it meets all core substitution criteria except lifetime. The rated lifetime is 2000 hours at 85°C instead of 3000 hours. This part is suitable only for applications where the reduced lifetime specification is acceptable. Verify application requirements before selection.

Q: Will the taller height of some substitute parts cause installation problems?

A: Three substitute parts have a maximum seated height of 1.260" (32.00 mm) compared to 1.181" (30.00 mm) for the original ECO-S1KP332DA. This 0.079" (2.00 mm) difference may affect mechanical clearance in space-constrained applications. Verify available vertical clearance in your circuit board layout before selection. SLPX332M080E3P3 maintains the original 1.181" (30.00 mm) height.

Q: Are all substitute parts RoHS compliant?

A: All active substitute parts listed (380LX332M080K022, 80USG3300MEFCSN30X30, B41231C0338M000, and SLPX332M080E3P3) are ROHS3 compliant. The original ECO-S1KP332DA RoHS status is not specified in available documentation.

Q: Which substitute part has the best inventory availability?

A: SLPX332M080E3P3 has the highest inventory availability with 9173 units in stock. 80USG3300MEFCSN30X30 has 969 units, 380LX332M080K022 has 851 units, and B41231C0338M000 has 1271 units available.

Q: Can I mix different substitute parts in the same circuit board?

A: All listed substitute parts are electrically and mechanically compatible with the ECO-S1KP332DA and with each other. Mixing different manufacturers or part numbers in the same design is acceptable from an electrical standpoint. However, verify that your procurement and quality assurance processes support multiple part numbers for the same function.
