Engineering Selection Recommendations

SLPX332M080C7P3 (Cornell Dubilier Electronics - CDE):

This part qualifies as a direct manufacturer substitute. Both the 338LBB080M2CF and SLPX332M080C7P3 originate from Cornell Dubilier, ensuring consistent manufacturing standards and quality control protocols. The SLPX332M080C7P3 maintains identical electrical specifications (3300 µF, 80 V, ±20% tolerance) and mechanical compatibility (radial snap-in package, 10.00mm lead spacing, 25.00mm diameter). The ESR specification of 101 mOhm at 120 Hz represents a measurable increase from the primary part's 75.36 mOhm, which may impact ripple current handling in high-frequency applications but remains within acceptable parameters for general-purpose use. The seated height of 1.575" (40.00mm) is 0.079" lower than the primary part, providing improved clearance in space-constrained designs. Both parts are ROHS3 compliant and carry Active product status.

LLS1K332MELA (Nichicon):

This part qualifies as a parametric equivalent from an alternative manufacturer. The Nichicon LLS1K332MELA matches all critical electrical parameters (3300 µF, 80 V, ±20% tolerance, 3000 Hrs @ 85°C) and mechanical specifications (radial snap-in package, 10.00mm lead spacing, 25.00mm diameter). The ESR specification is not provided in available documentation. The seated height of 1.654" (42.00mm) matches the primary part exactly. Ripple current at 120 Hz is specified at 3.29 A, compared to 3.21 A for the primary part. The part is ROHS3 compliant and carries Active product status. Selection of this substitute is appropriate when Cornell Dubilier sourcing is unavailable and Nichicon supply chain access is established.

All three parts are suitable for direct substitution in applications where the 338LBB080M2CF is specified, provided that design margins accommodate the documented performance variations.

Frequently Asked Questions (FAQ)

Q: Can SLPX332M080C7P3 be used as a direct replacement for 338LBB080M2CF?

A: Yes. Both parts are manufactured by Cornell Dubilier and share identical capacitance (3300 µF), voltage rating (80 V), tolerance (±20%), package type (radial snap-in), lead spacing (10.00mm), and diameter (25.00mm). The ESR difference (101 mOhm vs. 75.36 mOhm) and height difference (1.575" vs. 1.654") are within acceptable substitution parameters for general-purpose applications.

Q: What is the significance of the ESR difference between 338LBB080M2CF and SLPX332M080C7P3?

A: ESR (Equivalent Series Resistance) affects ripple current handling and heat dissipation. The SLPX332M080C7P3 has higher ESR (101 mOhm vs. 75.36 mOhm), which results in slightly increased power loss under ripple current conditions. Applications with high ripple current requirements should verify that the SLPX332M080C7P3 ripple current rating (3.29 A @ 120 Hz) meets design specifications.

Q: Is the height difference between SLPX332M080C7P3 (1.575") and 338LBB080M2CF (1.654") significant?

A: The SLPX332M080C7P3 is 0.079" shorter, which provides additional clearance in space-constrained designs. This difference is not a compatibility issue; it represents an advantage in applications with vertical space limitations. PCB footprint and lead spacing remain identical.

Q: Can LLS1K332MELA from Nichicon be used interchangeably with 338LBB080M2CF?

A: Yes. The Nichicon LLS1K332MELA meets all critical electrical and mechanical specifications: 3300 µF capacitance, 80 V voltage rating, ±20% tolerance, 3000 Hrs @ 85°C lifetime, radial snap-in package, 10.00mm lead spacing, and 25.00mm diameter. The seated height (1.654") matches the primary part exactly. Selection of this substitute is appropriate when Cornell Dubilier parts are unavailable.

Q: Are all three parts RoHS3 compliant?

A: Yes. The 338LBB080M2CF, SLPX332M080C7P3, and LLS1K332MELA are all ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: What is the lead spacing specification, and why is it important?

A: All three parts have identical lead spacing of 0.394" (10.00mm). This specification determines PCB footprint compatibility. Identical lead spacing ensures that all three parts can be mounted on the same printed circuit board without modification to pad layout or hole positioning.

Q: Do all substitute parts have the same operating temperature range?

A: Yes. All three parts operate across the identical temperature range of -40°C to 85°C, ensuring thermal compatibility in applications with variable environmental conditions.

Q: What does "Snap-In" package type mean?

A: Snap-In refers to the mechanical mounting method where the capacitor's leads are inserted into PCB holes and secured by a snap-fit mechanism, as opposed to solder-only attachment. All three parts use this mounting type, ensuring mechanical compatibility.
