Engineering Selection Recommendations

All three substitute parts satisfy the core electrical and mechanical substitution criteria for the ECO-S1KP182BA. Selection should be based on the following factors:

380LX182M080H032 (Cornell Dubilier Electronics): This part provides the closest electrical match with identical ESR (147 mOhm @ 120 Hz) and lifetime rating (3000 Hrs @ 85°C). It is ROHS3 compliant and currently in active production status. Physical height is 1.457" (37.00 mm), which is 0.079" taller than the original part. This difference must be verified against available board space.

B41231A0188M000 (EPCOS - TDK Electronics): This part offers the most compact physical profile at 1.260" (32.00 mm) height, providing 0.118" clearance advantage over the original design. However, the lifetime rating is reduced to 2000 Hrs @ 85°C, and ESR is not specified. ROHS3 compliance is confirmed. This option is suitable for space-constrained applications where the reduced lifetime rating is acceptable.

SLP182M080A5P3 (Cornell Dubilier Electronics): This part features an extended operating temperature range (-40°C to 105°C) and maintains the 3000-hour lifetime rating at the higher temperature. ESR is slightly elevated at 184 mOhm @ 120 Hz. Physical dimensions match the original part exactly. ROHS3 compliance is confirmed. This option is recommended for applications requiring enhanced thermal performance.

Frequently Asked Questions (FAQ)

Q: Can the 380LX182M080H032 be used as a direct replacement for the ECO-S1KP182BA?

A: Yes. The 380LX182M080H032 meets all critical electrical and mechanical substitution parameters: 1800 µF capacitance, 80 V rating, ±20% tolerance, identical ESR, matching lead spacing, and snap-in package configuration. The physical height difference of 0.079" must be verified against available PCB clearance.

Q: What is the primary difference between the B41231A0188M000 and the other substitutes?

A: The B41231A0188M000 provides the smallest physical footprint (1.260" height) but operates with a reduced lifetime specification of 2000 Hrs @ 85°C compared to 3000 Hrs for the other options. This trade-off between size and operational longevity must be evaluated against system requirements.

Q: Why does the SLP182M080A5P3 have a higher ESR value?

A: The SLP182M080A5P3 is specified with an extended operating temperature range (-40°C to 105°C) and maintains its 3000-hour lifetime at 105°C. The slightly elevated ESR (184 mOhm @ 120 Hz versus 147 mOhm) reflects design optimization for thermal performance rather than a functional limitation.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three substitute parts are ROHS3 compliant. The original ECO-S1KP182BA is RoHS non-compliant, making these substitutes suitable for applications requiring regulatory compliance.

Q: What is the impact of the height differences on PCB layout?

A: The 380LX182M080H032 is 0.079" taller than the original part, while the B41231A0188M000 is 0.118" shorter. The SLP182M080A5P3 matches the original height exactly. Physical clearance verification is required before final component selection to ensure compatibility with surrounding circuit elements and enclosure constraints.
