Frequently Asked Questions (FAQ)

Q: Can 380LX153M035A022 be used as a direct replacement for 159LBA035M2EE?

A: Yes. Both parts share identical capacitance (15000 µF), voltage rating (35 V), tolerance (±20%), package style (Radial, Can - Snap-In), lead spacing (10.00mm), and diameter (35.00mm). The 380LX series offers improved ESR (36 mOhm vs. 44.21 mOhm) and extended lifetime (3000 Hrs vs. 2000 Hrs) at 85°C. The reduced height (30.00mm vs. 37.00mm) must be verified for mechanical fit in the application.

Q: What is the difference between the 381LX153M035A032 and 159LBA035M2EE?

A: Both parts are mechanically and electrically identical except for thermal performance. The 381LX series extends the operating temperature range to 105°C (vs. 85°C) and provides 3000-hour lifetime at 105°C. Physical dimensions are identical. This upgrade is suitable for applications requiring operation or storage at temperatures above 85°C.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the regulatory requirements of the 159LBA035M2EE.

Q: Which substitute offers the lowest ESR?

A: The 380LX153M035A022 provides the lowest specified ESR at 36 mOhm @ 120Hz, compared to 44.21 mOhm for the 159LBA035M2EE. Lower ESR reduces heat generation and improves efficiency in ripple current applications.

Q: Can I use LGU1V153MELC in an application limited to 85°C operation?

A: Yes. The LGU1V153MELC is rated for -40°C ~ 105°C operation, which encompasses the 85°C requirement. The extended temperature rating does not restrict use in lower-temperature applications. All other electrical and mechanical parameters are compatible.

Q: What is the physical height difference between 380LX153M035A022 and 159LBA035M2EE?

A: The 380LX153M035A022 has a maximum seated height of 1.181" (30.00mm), while the 159LBA035M2EE is 1.457" (37.00mm). This 7mm reduction must be verified for mechanical clearance in the application before substitution.

Q: Which substitute has the highest ripple current rating at 120Hz?

A: The B41231B7159M000 provides the highest ripple current rating at 5.88 A @ 120Hz, compared to 5 A for the 159LBA035M2EE. This indicates superior current handling capability in low-frequency ripple applications.

Q: Are there inventory considerations for these substitutes?

A: Inventory levels vary by part number. The 380LX153M035A022 has the highest stock (2923 pcs), while LGU1V153MELC has the lowest (723 pcs). Availability should be confirmed for production planning.
