Engineering Selection Recommendations

All three parts—SLP153M035H5P3, 381LX153M035A032, and 381LX153M035K452—maintain Active product status and full ROHS3 compliance with REACH Unaffected classification. Selection between these parts is determined by physical space constraints and ripple current requirements specific to the application circuit.

SLP153M035H5P3 is the primary reference part with specified ESR of 35 mOhm @ 120 Hz and ripple current capability of 4.88 A @ 20 kHz. This part is suitable for applications with moderate to high-frequency ripple current demands.

381LX153M035A032 provides equivalent electrical performance with matching ripple current at 120 Hz (3.9 A) and slightly reduced ripple current at 20 kHz (4.5 A). Physical dimensions are nearly identical to the main part, with a maximum seated height of 1.457" (37.00mm) compared to 1.378" (35.00mm). This part is suitable for applications where the additional 0.079" height is accommodated within PCB layout constraints.

381LX153M035K452 offers the same electrical specifications with reduced diameter (1.181" vs. 1.378") and increased height (1.850" maximum seated). This configuration is suitable for applications with horizontal space limitations but adequate vertical clearance. The smaller diameter may provide layout advantages in compact designs.

All substitute parts maintain the critical 0.394" (10.00mm) lead spacing required for PCB compatibility and snap-in mounting functionality.

Frequently Asked Questions (FAQ)

Q: Can 381LX153M035A032 be used as a direct replacement for SLP153M035H5P3?

A: Yes. Both parts share identical capacitance (15000 µF), voltage rating (35 V), tolerance (±20%), operating temperature range (-40°C to 105°C), and lifetime rating (3000 Hrs @ 105°C). Lead spacing is identical at 0.394" (10.00mm). The primary difference is seated height: 1.457" versus 1.378". Verify that the additional 0.079" height is accommodated in your PCB layout before substitution.

Q: What is the difference between 381LX153M035A032 and 381LX153M035K452?

A: Both parts are electrically equivalent with identical capacitance, voltage, tolerance, and temperature specifications. The key differences are physical dimensions. The 381LX153M035A032 has a diameter of 1.378" (35.00mm) and height of 1.457" (37.00mm). The 381LX153M035K452 has a smaller diameter of 1.181" (30.00mm) but greater height of 1.850" (47.00mm). Select based on available PCB space: use 381LX153M035A032 if horizontal space is available, or 381LX153M035K452 if vertical space is available but horizontal space is constrained.

Q: Are all three parts RoHS compliant?

A: Yes. SLP153M035H5P3, 381LX153M035A032, and 381LX153M035K452 are all ROHS3 Compliant with REACH Unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: Does ripple current capacity differ between these parts?

A: Ripple current at 120 Hz is identical across all three parts at 3.9 A. At 20 kHz, the SLP153M035H5P3 is rated for 4.88 A, while both 381LX substitutes are rated for 4.5 A. For applications with high-frequency ripple current demands exceeding 4.5 A @ 20 kHz, the SLP153M035H5P3 is required. For applications within 4.5 A @ 20 kHz, all three parts are suitable.

Q: What is the significance of lead spacing in substitution?

A: Lead spacing of 0.394" (10.00mm) is critical for PCB compatibility. All three parts maintain this identical spacing, ensuring that PCB footprints and through-hole mounting positions remain unchanged during substitution. This parameter is non-negotiable for direct replacement.

Q: Can these parts be used interchangeably in production?

A: Yes, provided that physical dimensions are verified against PCB layout constraints. All three parts are Active status from Cornell Dubilier Electronics with identical electrical specifications, regulatory compliance, and lead spacing. Production substitution is valid when the specific part's physical dimensions fit within the available PCB space.
