Engineering Selection Recommendations

Both the SLPX471M350E5P3 and LLS2V471MELB are Active product status components with full ROHS3 and REACH compliance. Selection between these equivalents is based on inventory availability and sourcing lead times. The Nichicon LLS2V471MELB demonstrates significantly higher inventory availability (273,882 pcs in stock versus 665 pcs for the Cornell Dubilier part), making it suitable for high-volume applications where supply chain continuity is critical.

Frequently Asked Questions (FAQ)

Q: Can the LLS2V471MELB be used as a direct replacement for the SLPX471M350E5P3?

A: Yes. Both parts are parametric equivalents with identical capacitance (470 µF), voltage rating (350 V), tolerance (±20%), physical dimensions, lead spacing, mounting type, operating temperature range, and lifetime specifications.

Q: What are the mechanical compatibility requirements for substitution?

A: The substitute part must maintain identical through-hole lead spacing of 0.394" (10.00mm), radial can snap-in package configuration, and maximum seated height of 1.457" (37.00mm). Both parts meet these requirements.

Q: Are there differences in ripple current specifications between the two parts?

A: At 120 Hz, both parts specify 2.53 A ripple current. At higher frequencies, the Nichicon part specifies 3.6179 A @ 50 kHz, while the original part specifies 3.72 A @ 20 kHz. These differences do not disqualify substitution as both support the specified operating conditions.

Q: Do compliance certifications differ between the two parts?

A: No. Both parts are ROHS3 compliant and REACH Unaffected with identical ECCN (EAR99) and HTSUS (8532.22.0040) classifications.
