Engineering Selection Recommendations

All three substitute parts maintain Active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment with the original SLP223M035H4P3.

SLP223M035H9P3 demonstrates the highest electrical parameter alignment with the main part, sharing identical ESR specification (24 mOhm @ 120Hz) and series designation (SLP0712TE 750W). Height variation of 5.00 mm (50.00 mm vs. 45.00 mm seated height) requires mechanical envelope verification in target applications. Inventory availability is 3402 units.

381LX223M035A052 provides qualified substitution with mechanical compatibility across all critical dimensions except seated height (52.00 mm vs. 45.00 mm). ESR specification is not provided for this part. Lead spacing and diameter match the original specification. Inventory availability is 3115 units.

383LX223M035A052 qualifies as a substitute with the distinction of a 4-lead snap-in configuration versus the standard 2-lead design. Seated height is 52.00 mm. Lead spacing is not specified. This configuration requires verification of PCB footprint compatibility. Inventory availability is 1179 units.

Selection between substitute parts should prioritize mechanical envelope constraints of the target application, particularly seated height limitations. All parts satisfy electrical performance requirements for general-purpose applications.

Frequently Asked Questions (FAQ)

Q: Can SLP223M035H9P3 be used as a direct replacement for SLP223M035H4P3?

A: Yes. SLP223M035H9P3 meets all mandatory equivalence criteria including capacitance (22000 µF), voltage rating (35 V), tolerance (±20%), ESR (24 mOhm @ 120Hz), lifetime (3000 Hrs @ 105°C), operating temperature range (-40 to 105°C), and package configuration (Radial, Can - Snap-In). The seated height difference of 5.00 mm (50.00 mm vs. 45.00 mm) requires verification that the target application PCB layout and enclosure accommodate this dimension.

Q: What is the difference between 381LX223M035A052 and 383LX223M035A052?

A: Both parts share identical electrical specifications (22000 µF, 35 V, ±20%, 3000 Hrs @ 105°C) and mechanical diameter (35.00 mm). The primary distinction is package configuration: 381LX223M035A052 is a standard 2-lead radial snap-in design, while 383LX223M035A052 is a 4-lead radial snap-in design. Additionally, 383LX223M035A052 has a seated height of 52.00 mm compared to 381LX223M035A052 at 52.00 mm. The 4-lead configuration of 383LX223M035A052 requires PCB footprint compatibility verification.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts (381LX223M035A052, 383LX223M035A052, SLP223M035H9P3) are ROHS3 Compliant, matching the compliance status of the original SLP223M035H4P3.

Q: What is the impact of seated height variation on substitution?

A: Seated height variation affects mechanical fit within the target application. The original SLP223M035H4P3 has a maximum seated height of 45.00 mm. Substitute parts 381LX223M035A052 and 383LX223M035A052 have seated heights of 52.00 mm (7.00 mm taller), while SLP223M035H9P3 has a seated height of 50.00 mm (5.00 mm taller). Applications with tight vertical clearance constraints must verify that the substitute part height does not exceed available space on the PCB or within the enclosure.

Q: Do all substitute parts have the same ESR specification?

A: No. SLP223M035H9P3 specifies ESR at 24 mOhm @ 120Hz, matching the original SLP223M035H4P3. Parts 381LX223M035A052 and 383LX223M035A052 do not provide ESR specifications in the available data. Applications requiring specific ESR performance should prioritize SLP223M035H9P3 or request ESR data from the manufacturer for the 381LX and 383LX series.

Q: Is lead spacing identical across all parts?

A: Lead spacing is specified as 10.00 mm for SLP223M035H4P3, 381LX223M035A052, and SLP223M035H9P3. Lead spacing is not specified for 383LX223M035A052. PCB footprint compatibility should be verified before selecting 383LX223M035A052, particularly given its 4-lead configuration.

Q: Can these parts be used interchangeably in high-ripple-current applications?

A: Ripple current ratings vary across the parts. SLP223M035H4P3 specifies 5.24 A @ 120 Hz and 6.55 A @ 20 kHz. 381LX223M035A052 specifies 5 A @ 120 Hz and 5.8 A @ 20 kHz. SLP223M035H9P3 ripple current specifications are not provided in the available data. Applications with specific ripple current requirements should verify that the selected substitute part meets or exceeds the thermal and electrical demands of the circuit.
