Parameter Comparison

Engineering Selection Recommendations

Substitution Validity:

Both 381LX682M050A022 and LGU1H682MELB are valid direct substitutes for LP682M050E7P3 based on electrical and mechanical parameter equivalence. All three parts maintain identical capacitance (6800 µF), voltage rating (50 V), tolerance (±20%), polarization (Polar), mounting configuration (Through Hole, Radial Can - Snap-In), and lead spacing (0.394" / 10.00mm).

Compliance Alignment:

All three parts are ROHS3 Compliant and REACH Unaffected, satisfying regulatory requirements for industrial and commercial applications. Product status is Active for all variants, ensuring continued availability and manufacturing support.

Operational Characteristics:

The substitute parts 381LX682M050A022 and LGU1H682MELB provide extended operational lifetime (3000 Hrs @ 105°C versus 1000 Hrs @ 105°C for the main part) and equivalent or superior ripple current handling. These characteristics represent performance enhancements rather than deviations from the original specification.

Physical Compatibility Considerations:

The 381LX682M050A022 exhibits increased diameter (1.378" / 35.00mm) and reduced height (1.260" / 32.00mm) compared to the main part. The LGU1H682MELB maintains identical diameter (1.181" / 30.00mm) with slightly reduced height (1.457" / 37.00mm). PCB layout verification is required to confirm mechanical fit within the intended application.

Inventory and Availability:

Current stock levels: LP682M050E7P3 (847 Pcs), 381LX682M050A022 (4910 Pcs), LGU1H682MELB (1777 Pcs). Selection may be influenced by delivery requirements and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can LP682M050E7P3 be directly replaced with 381LX682M050A022 or LGU1H682MELB without circuit modification?

A: Yes. Both substitute parts maintain identical electrical specifications (6800 µF, 50 V, ±20% tolerance) and mounting configuration (Through Hole, Radial Can - Snap-In with 0.394" lead spacing). No circuit modification is required. Physical dimensions must be verified against PCB layout constraints.

Q: What is the primary difference between the main part and the substitute parts?

A: The main part LP682M050E7P3 specifies 1000 Hrs operational lifetime at 105°C. Both substitute parts provide 3000 Hrs lifetime at the same temperature, representing extended operational durability. Ripple current ratings are also equivalent or superior in the substitute parts.

Q: Are there any compliance or regulatory differences between these three parts?

A: No. All three parts are ROHS3 Compliant and REACH Unaffected. Environmental and regulatory compliance is identical across LP682M050E7P3, 381LX682M050A022, and LGU1H682MELB.

Q: Does the physical size difference between 381LX682M050A022 and the other parts affect substitution?

A: Physical dimensions are variable parameters in substitution. The 381LX682M050A022 has a larger diameter (1.378" vs. 1.181") but shorter height (1.260" vs. 1.575"). PCB layout must accommodate these dimensional changes. Lead spacing (0.394" / 10.00mm) remains constant across all parts.

Q: Which substitute part should be selected if PCB space is limited?

A: The LGU1H682MELB maintains the same diameter as the main part (1.181" / 30.00mm) with comparable height (1.457" / 37.00mm), making it the preferred choice for space-constrained applications. The 381LX682M050A022 requires verification of increased diameter clearance.

Q: Are ESR (Equivalent Series Resistance) specifications available for the substitute parts?

A: ESR data is not provided for 381LX682M050A022 or LGU1H682MELB in the available specifications. The main part LP682M050E7P3 specifies 49 mOhm @ 120Hz. Ripple current ratings are provided for all parts and serve as functional performance indicators.

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

A: Yes. All three parts support equivalent or superior ripple current ratings. The main part specifies 3.16 A @ 120 Hz and 3.476 A @ 100 kHz. Substitute parts provide 3.3-3.39 A @ 120 Hz and 3.8-3.8985 A at higher frequencies, supporting high-ripple-current circuit requirements.

Q: What is the significance of the "Snap-In" package configuration?

A: Snap-In configuration indicates mechanical mounting through snap-fit terminals on the PCB, eliminating the need for solder connections at the capacitor leads. This configuration is identical across all three parts, ensuring mechanical compatibility with snap-in socket designs.

Q: Are there any manufacturer-specific considerations when selecting between CDE and Nichicon alternatives?

A: Both manufacturers are established suppliers of aluminum electrolytic capacitors. Selection may be based on supply chain preferences, inventory availability, or existing qualification requirements. Electrical and mechanical specifications are equivalent across all three parts.
