Part Overview

The SLPX223M025C9P3 is a 22000 µF, 25 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in a radial, can snap-in package. This component is designed for general-purpose applications requiring high capacitance values in through-hole mounting configurations. The part is Active in product status and fully compliant with RoHS3 and REACH regulations. Alternative equivalent parts become necessary when inventory constraints exist, when specific mechanical dimensions must accommodate board layout requirements, or when ESR characteristics require optimization for particular circuit performance parameters.

Substitute Part Grouping Explanation

Substitution eligibility for the SLPX223M025C9P3 is determined by strict electrical and mechanical parameter matching. All substitute parts must maintain identical capacitance (22000 µF), voltage rating (25 V), and tolerance (±20%). The operating temperature range (-40°C to 85°C) and lifetime specification (3000 Hrs @ 85°C) are non-negotiable for equivalent functionality.

Mechanical compatibility requires identical lead spacing (10.00 mm) and mounting type (Through Hole, Radial Can Snap-In). Variations in physical dimensions (diameter and height) are permissible only when the substitute part fits within the available board space and does not interfere with adjacent components.

ESR characteristics at 120 Hz may vary within acceptable limits. The main part specifies 27 mOhm; substitute parts with 30 mOhm ESR remain functionally equivalent as this difference does not exceed typical component tolerance ranges and does not compromise ripple current handling for general-purpose applications.

All substitute parts must maintain Active product status and comply with RoHS3 and REACH regulations to ensure long-term availability and regulatory compliance.

Engineering Selection Recommendations

All three substitute parts—SLPX223M025E7P3, 380LX223M025J052, and 380LX223M025K042—are electrically equivalent to the SLPX223M025C9P3 and maintain full compliance with RoHS3 and REACH regulations. Selection among these alternatives depends on mechanical space constraints and inventory availability.

SLPX223M025E7P3 is the closest electrical match, featuring identical ESR (27 mOhm) and the same SLPX series designation. This part has the largest available inventory (5740 Pcs) and a reduced height profile (40.00 mm vs. 50.00 mm), making it suitable for space-constrained applications. The increased diameter (30.00 mm) must be verified against board layout constraints.

380LX223M025J052 maintains the original diameter (25.00 mm) of the main part, simplifying PCB footprint compatibility. However, it features slightly higher ESR (30 mOhm) and increased height (52.00 mm). This part is appropriate when diameter constraints are critical and height accommodation is available.

380LX223M025K042 offers a balanced profile with reduced height (42.00 mm) and increased diameter (30.00 mm). It also features 30 mOhm ESR. This configuration suits applications where vertical space is limited but horizontal board area permits larger component diameter.

Selection should prioritize mechanical fit within the specific PCB layout, followed by inventory availability and ESR performance requirements for the target application.

Frequently Asked Questions (FAQ)

Q: Can SLPX223M025E7P3 be used as a direct replacement for SLPX223M025C9P3?

A: Yes. Both parts share identical electrical specifications: 22000 µF capacitance, 25 V rating, ±20% tolerance, 27 mOhm ESR, and 3000 Hrs @ 85°C lifetime. The primary difference is physical dimension: SLPX223M025E7P3 has a 30.00 mm diameter and 40.00 mm height compared to 25.00 mm diameter and 50.00 mm height. Verify that the larger diameter and reduced height accommodate your PCB layout.

Q: What is the significance of the ESR difference between 27 mOhm and 30 mOhm?

A: ESR (Equivalent Series Resistance) affects ripple current handling and heat dissipation. The 3 mOhm difference between SLPX223M025C9P3 (27 mOhm) and the 380LX series (30 mOhm) represents approximately an 11% increase. For general-purpose applications, this variation remains within acceptable performance margins. Applications with stringent ripple current requirements should prioritize parts with lower ESR values.

Q: Are the 380LX223M025J052 and 380LX223M025K042 interchangeable?

A: Both parts are electrically identical (22000 µF, 25 V, ±20%, 30 mOhm ESR, 3000 Hrs @ 85°C) and belong to the same 380LX series. They differ only in physical dimensions: 380LX223M025J052 is 25.00 mm diameter × 52.00 mm height; 380LX223M025K042 is 30.00 mm diameter × 42.00 mm height. Selection depends on available board space. They are not interchangeable if PCB footprint constraints are strict.

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

A: Yes. All substitute parts maintain 10.00 mm lead spacing, ensuring PCB footprint compatibility at the connection points. Differences in diameter and height do not affect lead spacing and do not require PCB redesign for through-hole mounting.

Q: What compliance certifications apply to all substitute parts?

A: All parts—SLPX223M025C9P3, SLPX223M025E7P3, 380LX223M025J052, and 380LX223M025K042—are RoHS3 Compliant and REACH Unaffected. All maintain Active product status, ensuring continued availability and regulatory compliance for new designs and production runs.

Q: Which substitute part has the best inventory availability?

A: SLPX223M025E7P3 has the highest inventory level at 5740 Pcs, followed by 380LX223M025J052 at 3125 Pcs. The original SLPX223M025C9P3 has 1004 Pcs in stock. Inventory levels should be verified at the time of procurement, as availability may change.

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

A: All parts support ripple current specifications. SLPX223M025C9P3 and SLPX223M025E7P3 (27 mOhm ESR) handle 5.29–5.33 A @ 120 Hz and 6.61–6.66 A @ 20 kHz. The 380LX series (30 mOhm ESR) handles 6.1 A @ 120 Hz and 7 A @ 20 kHz. Selection should match the application's ripple current requirements and thermal management capabilities.
