Engineering Selection Recommendations

Primary Part: SLPX102M350H9P3 (Cornell Dubilier Electronics)

The SLPX102M350H9P3 is the specified component with confirmed inventory of 794 pieces in stock. This part carries Active product status, full RoHS3 compliance, and REACH unaffected designation, meeting all regulatory requirements for current applications.

Substitute Part: LLS2V102MELC (Nichicon)

The LLS2V102MELC qualifies as a direct parametric equivalent based on matching electrical specifications (1000 µF, 350 V, ±20% tolerance, 3000 Hrs @ 85°C), identical mechanical dimensions (35.00 mm diameter, 52.00 mm height, 10.00 mm lead spacing), and identical package configuration (radial, can snap-in, through-hole mounting). Both parts maintain Active product status with RoHS3 compliance and REACH unaffected status.

The substitute part demonstrates significantly higher inventory availability (273,782 pieces) compared to the primary part, providing supply chain flexibility. Selection between these parts should be based on procurement lead time, cost considerations, and existing design validation history.

Frequently Asked Questions (FAQ)

Q: Can the LLS2V102MELC replace the SLPX102M350H9P3 in existing circuit designs?

A: Yes. The LLS2V102MELC meets all specified electrical and mechanical parameters required for direct substitution. Both parts share identical capacitance (1000 µF), voltage rating (350 V), tolerance (±20%), lifetime specification (3000 Hrs @ 85°C), operating temperature range (-25°C to 85°C), and physical dimensions (35.00 mm diameter, 52.00 mm height, 10.00 mm lead spacing). Both employ identical radial, can snap-in package configuration with through-hole mounting.

Q: Are there differences in performance between these two parts?

A: The primary documented difference is ESR specification. The SLPX102M350H9P3 specifies 199 mOhm ESR @ 120 Hz, while the LLS2V102MELC does not provide ESR data in the available specifications. Both parts deliver equivalent ripple current performance at low frequency (3.6 A @ 120 Hz). High-frequency ripple current specifications differ slightly due to different measurement frequencies (5.29 A @ 20 kHz for SLPX versus 5.148 A @ 50 kHz for LLS).

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the SLPX102M350H9P3 and LLS2V102MELC carry RoHS3 compliance and REACH unaffected designation, meeting current regulatory standards for electronic component manufacturing and use.

Q: What are the physical installation considerations?

A: Both parts are identical in physical configuration. Lead spacing is 10.00 mm, diameter is 35.00 mm, and maximum seated height is 52.00 mm. Both employ through-hole mounting with snap-in can package design. PCB footprint and mounting hardware requirements are identical.

Q: Which part should be selected for new designs?

A: Selection should be based on procurement availability, cost, and supply chain considerations. Both parts carry Active product status and meet all specified requirements. The LLS2V102MELC offers significantly higher inventory availability (273,782 pieces versus 794 pieces), which may provide supply chain advantages for high-volume production.
