Key Parameters

Substitute Part Grouping Explanation

Substitution of the LP682M063H9P3 is determined by strict adherence to the following critical parameters:

Core Electrical Parameters (Non-negotiable):

• Capacitance: 6800 µF (exact match required)
• Voltage Rating: 63 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Operating Temperature Range: -40°C to 105°C (must be met or exceeded)

Core Mechanical Parameters (Non-negotiable):

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

Secondary Parameters (Allow Variations):

• Lifetime @ Temperature: Substitutes with extended lifetime (1000 hrs minimum at 105°C) are acceptable
• ESR (Equivalent Series Resistance): Variations are acceptable provided the part meets electrical performance requirements
• Physical Dimensions (Diameter and Height): Variations within the snap-in can format are acceptable provided board layout permits

All identified substitute parts meet these criteria and maintain full electrical and mechanical compatibility with the original component.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts (381LX682M063A042, 381LX682M063K052, SLP682M063E9P3, and SLP682M063H7P3) carry Active product status from Cornell Dubilier Electronics and meet ROHS3 Compliant and REACH Unaffected regulatory requirements, matching the original LP682M063H9P3 component.

Selection among substitute parts should be based on:

Extended Lifetime Models: The 381LX and SLP series substitutes provide 3000 Hrs @ 105°C rated lifetime, compared to 1000 Hrs @ 105°C for the original LP series. These extended-lifetime alternatives are suitable for applications requiring enhanced thermal stability over extended operational periods.

Physical Dimensions: While all parts maintain the critical 0.394" (10.00 mm) lead spacing required for board compatibility, substitute parts exhibit variations in diameter and height:

• 381LX682M063A042 and SLP682M063H7P3: 1.378" (35.00 mm) diameter, matching the original
• 381LX682M063K052: 1.181" (30.00 mm) diameter (smaller footprint)
• SLP682M063E9P3: 1.181" (30.00 mm) diameter (smaller footprint)

Physical space availability in the target PCB assembly should dictate selection when footprint optimization is required.

ESR Considerations: The SLP series (SLP682M063E9P3 and SLP682M063H7P3) specify 59 mOhm ESR, compared to 37 mOhm for the original LP682M063H9P3. The 381LX series does not specify ESR values. Higher ESR introduces additional heat dissipation and may impact applications sensitive to impedance characteristics at operating frequencies.

Frequently Asked Questions (FAQ)

Q: Can I use substitute parts interchangeably with the LP682M063H9P3?

A: All identified substitute parts are electrical and mechanical equivalents. The 6800 µF capacitance, 63 V voltage rating, ±20% tolerance, and 0.394" (10.00 mm) lead spacing are identical across all parts. Interchangeability is determined by physical space constraints on the printed circuit board assembly. Verify that the diameter and height of the selected substitute do not exceed available board clearance before installation.

Q: Which substitute part offers the longest operational lifetime?

A: The 381LX682M063A042, 381LX682M063K052, SLP682M063E9P3, and SLP682M063H7P3 all provide 3000 Hrs @ 105°C lifetime, exceeding the original LP682M063H9P3 rating of 1000 Hrs @ 105°C. Selection among these four parts should be based on PCB layout constraints and ESR requirements for the specific application circuit.

Q: Does ESR variation between substitute parts affect circuit performance?

A: ESR differences exist among the substitute parts. The original LP682M063H9P3 specifies 37 mOhm @ 120 Hz, while the SLP series substitutes specify 59 mOhm. ESR impacts impedance characteristics and thermal behavior within the capacitor. Applications sensitive to high-frequency ripple current filtering or low-impedance power delivery may exhibit different performance characteristics depending on which substitute is selected. Confirm that circuit specifications permit the ESR range of the chosen alternative.

Q: Are all substitute parts RoHS compliant?

A: Yes, all identified substitute parts (381LX682M063A042, 381LX682M063K052, SLP682M063E9P3, and SLP682M063H7P3) are ROHS3 Compliant and REACH Unaffected, matching the original LP682M063H9P3 environmental status.

Q: Can I use a smaller diameter capacitor if board space is limited?

A: The 381LX682M063K052 and SLP682M063E9P3 offer reduced diameter (1.181" / 30.00 mm) compared to the original (1.378" / 35.00 mm) while maintaining identical capacitance, voltage rating, and lead spacing. Physical fit on the target PCB assembly must be confirmed. Height variation between these alternatives may also affect clearance requirements; compare all three physical dimensions against available board space before selection.
