Engineering Selection Recommendations

For Direct Replacement with Identical Footprint: Select 381LX152M100A012. This part maintains the exact physical dimensions of the ECO-S2AA152EA (1.378" diameter, 1.063" height) and requires no PCB layout modifications. The part is active and RoHS3 compliant, ensuring long-term availability and regulatory compliance.

For Space-Constrained Applications: Select SLP152M100A7P3 (smallest diameter at 0.866") or SLP152M100E1P3 (compact height at 0.984"). These alternatives provide electrical equivalence with reduced footprint requirements. Both are active products with RoHS3 compliance.

For Standard PCB Layouts: Select SLP152M100C5P3 or SLP152M100E3P3. Both maintain moderate dimensions (0.984" to 1.181" diameter, 1.181" to 1.378" height) and are active products with full RoHS3 compliance.

All substitute parts are manufactured by Cornell Dubilier Electronics, an established supplier with active product status, ensuring supply chain continuity and regulatory compliance across all options.

Frequently Asked Questions (FAQ)

Q: Can SLP152M100A7P3 be used as a direct replacement for ECO-S2AA152EA?

A: SLP152M100A7P3 is electrically equivalent with matching capacitance (1500 µF), voltage (100 V), tolerance (±20%), lead spacing (10.00 mm), and thermal specifications (3000 Hrs @ 105°C). However, it has a smaller diameter (0.866" vs. 1.378") and greater height (1.575" vs. 1.063"), requiring PCB layout verification before implementation.

Q: What is the difference between the SLP series and 381LX series substitutes?

A: The SLP series (SLP152M100A7P3, SLP152M100C5P3, SLP152M100E1P3, SLP152M100E3P3) offers multiple dimensional variants while maintaining electrical equivalence. The 381LX series (381LX152M100A012) provides an exact dimensional match to the original part. Both series meet all electrical and thermal requirements.

Q: Why does 381LX152M100A012 not specify ESR?

A: ESR specification is not provided in the available data for 381LX152M100A012. The original ECO-S2AA152EA specifies 122 mOhm @ 120 Hz, while SLP series parts specify 177 mOhm @ 120 Hz. ESR values should be confirmed with the manufacturer if this parameter is critical for the application.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts (SLP152M100A7P3, SLP152M100C5P3, SLP152M100E1P3, SLP152M100E3P3, and 381LX152M100A012) are RoHS3 compliant. The original ECO-S2AA152EA does not specify RoHS status.

Q: What is the lead spacing requirement, and do all substitutes meet it?

A: Lead spacing is 0.394" (10.00 mm) for the ECO-S2AA152EA. All substitute parts maintain this identical lead spacing, ensuring compatibility with existing PCB designs without modification.

Q: Can I use multiple substitute parts interchangeably in the same design?

A: All substitute parts meet the same electrical specifications (1500 µF, 100 V, ±20%, 3000 Hrs @ 105°C). However, physical dimensions vary. If PCB layout accommodates the dimensional variations, parts are interchangeable. If space is constrained, select the specific part matching your available footprint.
