Engineering Selection Recommendations

All listed substitute parts meet the core electrical and mechanical requirements for direct substitution. Selection should be based on the following factors:

Product Status: The ECO-S1KP152BA is obsolete. All substitute parts listed are active products with ongoing manufacturing support and availability.

Compliance: All substitute parts carry ROHS3 compliance certification, ensuring regulatory alignment for new designs and production environments.

Physical Fit: The 380LX152M080H022, 80USG1500MEFCSN22X30, and B41231A158M have a maximum seated height of 1.260" (32.00 mm), compared to the original part's 1.181" (30.00 mm). Verify PCB layout clearance before selection. The SLP152M080A3P3 and SLPX152M080A3P3 maintain the original 1.181" (30.00 mm) height.

ESR Characteristics: The 380LX152M080A3P3 matches the original ESR specification of 177 mOhm @ 120Hz. The SLP152M080A3P3 and SLPX152M080A3P3 have higher ESR at 221 mOhm @ 120Hz. The 80USG1500MEFCSN22X30 and B41231A158M do not specify ESR values.

Lifetime Rating: The 380LX152M080H022, 80USG1500MEFCSN22X30, SLP152M080A3P3, and SLPX152M080A3P3 all provide 3000-hour lifetime at 85°C, matching the original specification. The B41231A158M provides 2000-hour lifetime at 85°C.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different height? A: Height differences must be evaluated against your specific PCB layout and mechanical constraints. The 380LX152M080H022, 80USG1500MEFCSN22X30, and B41231A158M are 0.079" (2.00 mm) taller than the original. Verify clearance in your assembly before selection.

Q: What does ESR mean and why does it matter? A: Equivalent Series Resistance (ESR) affects the capacitor's ability to handle ripple current and influences circuit performance at high frequencies. The 380LX152M080H022 matches the original ESR specification. Higher ESR values in alternative parts may impact performance in ripple-current-sensitive applications.

Q: Are all substitute parts RoHS compliant? A: Yes, all listed substitute parts carry ROHS3 compliance certification, suitable for applications requiring regulatory compliance.

Q: What is the difference between direct and parametric equivalents? A: Direct equivalents (380LX152M080H022, 80USG1500MEFCSN22X30, B41231A158M, SLP152M080A3P3) are manufacturer-specified substitutes. The SLPX152M080A3P3 is a parametric equivalent, meeting all core electrical and mechanical specifications but not formally designated as a direct substitute by the original manufacturer.

Q: Does operating temperature range affect substitution? A: The SLP152M080A3P3 operates to 105°C, exceeding the original specification of 85°C. This provides additional thermal margin but does not disqualify substitution for applications operating within the original -40°C to 85°C range.

Q: Which substitute offers the best overall compatibility? A: The 380LX152M080H022 provides the closest electrical match with identical ESR and lifetime specifications. The SLPX152M080A3P3 maintains the original height while offering extended thermal performance. Selection depends on your specific application requirements and PCB constraints.
