Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Electrical Match: Capacitance (3300 µF), voltage rating (100 V), and tolerance (±20%) must be identical
Thermal Performance: Lifetime rating of 3000 hours at 85°C is required
Operating Range: Temperature range of -40°C to 85°C must be maintained
Mechanical Compatibility: Radial, can snap-in package with through-hole mounting and 10.00 mm lead spacing
Compliance: ROHS3 compliance and REACH unaffected status required

All four substitute parts meet these criteria. Variations in physical dimensions (diameter and height) and ESR values are within acceptable ranges for this product category and do not affect functional substitution.

Engineering Selection Recommendations

All four substitute parts are active products with ROHS3 compliance and REACH unaffected status, matching the regulatory requirements of the primary part LLS2A332MELC.

The 380LX series (380LX332M100J052 and 380LX332M100K042) from Cornell Dubilier Electronics maintain identical electrical specifications with specified ESR values of 90 mOhm at 120 Hz. These parts differ in physical dimensions, with the J052 variant featuring a 0.984" diameter and 2.047" height, while the K042 variant has a 1.181" diameter and 1.654" height.

The SLPX series (SLPX332M100C9P3 and SLPX332M100E7P3) from Cornell Dubilier Electronics provide lower ESR values of 80 mOhm at 120 Hz and higher ripple current ratings at high frequency. The C9P3 variant has a 0.984" diameter and 1.969" height, while the E7P3 variant has a 1.181" diameter and 1.575" height.

Selection between substitute parts should be based on physical space constraints within the application and ESR performance requirements. All parts maintain the required 10.00 mm lead spacing for PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the LLS2A332MELC?

A: Yes, all four substitute parts meet the core electrical and mechanical specifications. However, physical dimensions vary. Verify that the selected substitute fits within the available PCB space and mounting constraints of your application.

Q: What is the significance of ESR differences between the parts?

A: ESR (Equivalent Series Resistance) affects ripple current handling and heat dissipation. The SLPX series offers lower ESR (80 mOhm) compared to the 380LX series (90 mOhm), resulting in improved high-frequency ripple current performance. Select based on your circuit's ripple current requirements.

Q: Are there physical dimension constraints I should consider?

A: Yes. The LLS2A332MELC has a diameter of 1.378" and height of 1.457". Substitute parts range from 0.984" to 1.181" in diameter and 1.575" to 2.047" in height. Verify that the selected substitute fits within your PCB layout and enclosure constraints.

Q: Do all substitute parts maintain the same lead spacing?

A: Yes. All parts, including the primary LLS2A332MELC and all four substitutes, maintain a 10.00 mm lead spacing, ensuring PCB footprint compatibility.

Q: Are there compliance or certification differences?

A: No. All parts are ROHS3 compliant and REACH unaffected, matching the regulatory status of the primary part.
