Substitute Part Grouping Explanation

Substitute parts for the SLP223M016C4P3 are identified based on strict electrical and mechanical parameter matching. The substitution logic requires exact alignment across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Capacitance: 22000 µF
• Voltage Rating: 16 V
• Tolerance: ±20%
• Polarization: Polar
• Operating Temperature Range: -40°C ~ 105°C
• Lifetime: 3000 Hrs @ 105°C

Mechanical Parameters (Must Match Exactly):

• Package Type: Radial, Can - Snap-In
• Lead Spacing: 0.394" (10.00mm)
• Mounting Type: Through Hole
• Diameter: 0.984" (25.00mm)

Compliance Parameters (Must Match):

• RoHS3 Compliant
• REACH Unaffected
• MSL Rating: 1 (Unlimited)

The 381LX223M016J452 qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Minor variations in physical height (1.850" vs 1.772") and ripple current specifications at high frequency remain within acceptable tolerance for general-purpose applications while maintaining identical core functionality.

Engineering Selection Recommendations

Primary Selection: SLP223M016C4P3

The SLP223M016C4P3 is the specified component and should be selected when available. This part carries full Active product status with documented ESR specification (30 mOhm @ 120 Hz) and higher ripple current capacity at high frequency (4.75 A @ 20 kHz). RoHS3 compliance and REACH unaffected status confirm regulatory alignment for current and future applications.

Substitute Selection: 381LX223M016J452

The 381LX223M016J452 qualifies as a direct electrical and mechanical substitute. Both components are manufactured by Cornell Dubilier Electronics and share identical capacitance, voltage rating, tolerance, package configuration, lead spacing, and thermal specifications. The substitute maintains RoHS3 compliance and REACH unaffected designation.

Selection Criteria:

1. Inventory Availability: Select the 381LX223M016J452 when SLP223M016C4P3 inventory is unavailable or lead times exceed project requirements.

2. Physical Space Constraints: The 381LX223M016J452 has a maximum seated height of 1.850" (47.00mm) compared to 1.772" (45.00mm) for the SLP223M016C4P3. Verify PCB clearance and enclosure dimensions before substitution in space-constrained applications.

3. High-Frequency Ripple Current: The SLP223M016C4P3 supports 4.75 A @ 20 kHz versus 4.4 A @ 20 kHz for the 381LX223M016J452. For applications with significant high-frequency ripple current demands, the SLP223M016C4P3 provides additional thermal margin.

4. Regulatory Compliance: Both parts satisfy RoHS3 and REACH requirements. No compliance differentiation exists between the two options.

5. Thermal Performance: Both components specify 3000 Hrs @ 105°C lifetime and identical operating temperature range (-40°C ~ 105°C). Thermal performance is equivalent.

Frequently Asked Questions (FAQ)

Q: Can the 381LX223M016J452 be used as a direct replacement for the SLP223M016C4P3 in all applications?

A: The 381LX223M016J452 is electrically and mechanically compatible for general-purpose applications. However, verify two parameters: (1) PCB clearance for the additional 2.00mm height, and (2) high-frequency ripple current requirements. If your application demands the full 4.75 A @ 20 kHz ripple current capacity, the SLP223M016C4P3 is the appropriate selection.

Q: What is the significance of the height difference between these two parts?

A: The 381LX223M016J452 has a maximum seated height of 1.850" (47.00mm) versus 1.772" (45.00mm) for the SLP223M016C4P3, a difference of 0.078" (2.00mm). This variation may impact PCB layout in applications with tight vertical clearance constraints, such as compact enclosures or stacked component arrangements. Verify available space before substitution.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the SLP223M016C4P3 and 381LX223M016J452 carry RoHS3 Compliant designation and REACH Unaffected status. No regulatory differentiation exists between the two options.

Q: What does the ±20% tolerance specification mean?

A: The ±20% tolerance indicates that the actual capacitance value may vary between 17600 µF and 26400 µF from the nominal 22000 µF specification. Both substitute parts share this identical tolerance specification, ensuring equivalent circuit behavior within the tolerance band.

Q: Why is the ripple current specification provided at two different frequencies?

A: Ripple current specifications at 120 Hz (low frequency) and 20 kHz (high frequency) characterize the capacitor's thermal performance under different operating conditions. The 120 Hz specification represents typical industrial power supply ripple, while 20 kHz represents switching power supply ripple. Both parts specify 3.8 A @ 120 Hz identically. The SLP223M016C4P3 provides higher capacity at 20 kHz (4.75 A vs 4.4 A), indicating superior high-frequency thermal performance.

Q: Can these capacitors be used in DC circuits only, or are they suitable for AC applications?

A: These are polar aluminum electrolytic capacitors designed for DC circuits with AC ripple current superimposed. They are not suitable for pure AC applications or circuits where polarity reversal occurs. The polar designation indicates that the positive and negative leads must be correctly oriented in the circuit.

Q: What does MSL Rating 1 (Unlimited) mean?

A: MSL (Moisture Sensitivity Level) Rating 1 indicates the lowest moisture sensitivity classification. These components can be stored indefinitely without special moisture control measures and do not require baking before soldering. This simplifies inventory management and assembly processes.

Q: Are both parts available in the same packaging format?

A: Yes. Both the SLP223M016C4P3 and 381LX223M016J452 are supplied in Bulk packaging as radial, can snap-in through-hole components with identical lead spacing (0.394" / 10.00mm) and diameter (0.984" / 25.00mm). They are mechanically interchangeable from a PCB footprint perspective, subject to height clearance verification.
