Substitute Part Grouping Explanation

Substitution of the SLP682M050C4P3 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance: 6800 µF (exact match)
• Voltage Rating: 50 V (exact match)
• Tolerance: ±20% (exact match)
• Lifetime: 3000 Hrs @ 105°C (exact match)
• Operating Temperature Range: -40°C ~ 105°C (exact match)
• Ripple Current @ 120 Hz: 3.3 A (exact match)
• Polarization: Polar (exact match)

Mechanical Compatibility Requirements:

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

Compliance Requirements:

• RoHS3 Compliant (exact match)
• REACH Unaffected (exact match)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match)

The substitute part 381LX682M050A022 meets all electrical and mechanical equivalence criteria. Physical dimensions (can diameter and height) may vary within the snap-in package design while maintaining lead spacing and mounting compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the SLP682M050C4P3 and 381LX682M050A022 are Active products manufactured by Cornell Dubilier Electronics and carry identical RoHS3 and REACH compliance certifications. Selection between these parts is based on the following factors:

SLP682M050C4P3 Selection Criteria:

• Compact form factor with 25.00mm diameter and 45.00mm height
• Higher ripple current capability at 20 kHz (4.13 A versus 3.8 A)
• Specified ESR of 68mOhm @ 120Hz for thermal performance calculations
• Applications requiring minimal board space with high-frequency ripple current handling

381LX682M050A022 Selection Criteria:

• Larger diameter (35.00mm) with reduced height (32.00mm) for specific PCB layout requirements
• Equivalent electrical performance at fundamental operating parameters
• Higher inventory availability (4910 Pcs versus 1063 Pcs)
• Applications where vertical space is constrained but horizontal space is available

Both parts satisfy identical electrical specifications for capacitance, voltage rating, tolerance, lifetime, operating temperature range, and low-frequency ripple current. The 381LX series exhibits 0.33 A lower ripple current at 20 kHz, which is a design consideration for high-frequency switching applications.

Frequently Asked Questions (FAQ)

Q: Can the 381LX682M050A022 be used as a direct replacement for the SLP682M050C4P3?

A: The 381LX682M050A022 is electrically equivalent for all fundamental parameters including capacitance, voltage rating, tolerance, lifetime, and operating temperature range. Both parts use identical lead spacing (10.00mm) and through-hole snap-in mounting. Physical dimensions differ: the substitute has a larger diameter (35.00mm versus 25.00mm) and smaller height (32.00mm versus 45.00mm). PCB layout compatibility must be verified before substitution.

Q: What is the difference in ripple current handling between these parts?

A: At 120 Hz, both parts handle 3.3 A ripple current identically. At 20 kHz, the SLP682M050C4P3 handles 4.13 A while the 381LX682M050A022 handles 3.8 A. For applications with significant high-frequency ripple current, the SLP682M050C4P3 provides higher current capacity. The difference is 0.33 A at 20 kHz.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the SLP682M050C4P3 and 381LX682M050A022 are ROHS3 Compliant and REACH Unaffected. Both carry Moisture Sensitivity Level 1 (Unlimited).

Q: What is the lead spacing for both parts?

A: Both parts have identical lead spacing of 0.394" (10.00mm), ensuring PCB footprint compatibility for through-hole mounting.

Q: Which part should be selected for space-constrained applications?

A: The SLP682M050C4P3 is more compact with a 25.00mm diameter and 45.00mm height. The 381LX682M050A022 has a larger diameter (35.00mm) but reduced height (32.00mm). Selection depends on whether vertical or horizontal space is the limiting factor in the PCB layout.

Q: Is ESR (Equivalent Series Resistance) specified for the substitute part?

A: The SLP682M050C4P3 specifies ESR of 68mOhm @ 120Hz. The 381LX682M050A022 does not provide ESR specification in the available data. For applications where ESR is a critical design parameter, the SLP682M050C4P3 is the specified choice.

Q: What is the product status of both parts?

A: Both parts are Active in product status, indicating current manufacturing and availability from Cornell Dubilier Electronics.
