LP223M016E7P3 Aluminum Electrolytic Capacitor - Equivalent & Substitute Parts

Part Overview

The LP223M016E7P3 is a 22000 µF, 16 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in the LP series. This radial, can-style snap-in capacitor is designed for general-purpose applications requiring high capacitance values in compact form factors. The part is currently active in production with 678 units in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters allow direct replacement in circuit applications. Substitution becomes necessary due to component availability, supply chain constraints, or design optimization requirements while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for aluminum electrolytic capacitors is determined by strict equivalence in the following parameters:

Primary Electrical Parameters:

• Capacitance value: 22000 µF (exact match required)
• Rated voltage: 16 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)

Mechanical Parameters:

• Mounting type: Through Hole (exact match required)
• Package style: Radial, Can - Snap-In (exact match required)
• Lead spacing: 0.394" (10.00mm) (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The substitute part 381LX223M016J452 meets all primary electrical, mechanical, and compliance requirements for direct substitution. Secondary performance parameters such as ESR, ripple current ratings, and lifetime specifications may vary within acceptable engineering tolerances for general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

Both LP223M016E7P3 and 381LX223M016J452 are active production parts manufactured by Cornell Dubilier Electronics with full ROHS3 compliance and unlimited moisture sensitivity rating. Selection between these parts is based on application-specific requirements:

LP223M016E7P3 Selection Criteria:

• Applications requiring compact radial can diameter (30.00mm)
• Designs with height constraints limited to 40.00mm maximum
• Specified ESR performance at 120 Hz (30 mOhm)

381LX223M016J452 Selection Criteria:

• Applications benefiting from extended lifetime rating (3000 Hrs @ 105°C versus 1000 Hrs)
• Designs accommodating larger height envelope (47.00mm maximum)
• Designs with smaller diameter footprint requirement (25.00mm)

Both parts satisfy identical electrical specifications (22000 µF, 16 V, ±20% tolerance) and mechanical mounting requirements (through-hole, snap-in package, 10.00mm lead spacing). Substitution is valid for general-purpose applications where the dimensional and lifetime variations do not conflict with circuit board layout or reliability requirements.

Frequently Asked Questions (FAQ)

Q: Can 381LX223M016J452 directly replace LP223M016E7P3 on existing PCBs?

A: Direct replacement is electrically valid. However, physical board layout compatibility must be verified. The 381LX series has a smaller diameter (25.00mm vs. 30.00mm) but greater height (47.00mm vs. 40.00mm). Confirm that the PCB mounting holes align with the 10.00mm lead spacing and that the increased height does not interfere with adjacent components or enclosure constraints.

Q: Are there differences in ripple current handling between these parts?

A: Yes. LP223M016E7P3 specifies 3.53 A @ 120 Hz and 3.883 A @ 100 kHz. 381LX223M016J452 specifies 3.8 A @ 120 Hz and 4.4 A @ 20 kHz. Applications with specific ripple current requirements must reference the appropriate part's datasheet to confirm suitability.

Q: What is the significance of the lifetime rating difference?

A: LP223M016E7P3 is rated for 1000 hours at 105°C, while 381LX223M016J452 is rated for 3000 hours at 105°C. For applications requiring extended operational life or operating continuously at elevated temperatures, the 381LX series provides superior reliability margin. For general-purpose applications with moderate duty cycles, both ratings are acceptable.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both LP223M016E7P3 and 381LX223M016J452 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the lead spacing tolerance, and does it affect interchangeability?

A: Both parts specify 0.394" (10.00mm) lead spacing. This dimension is the primary mechanical parameter determining PCB footprint compatibility. Identical lead spacing ensures that both parts fit the same mounting holes without modification.
