Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LP821M100E1P3 is determined by strict equivalence in the following parameters:

Critical Matching Parameters:

• Capacitance: 820 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: 100 V (exact match required)
• Polarization: Polar (exact match required)
• Package Type: Radial, Can - Snap-In (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lead Spacing: 10.00 mm (exact match required)
• Operating Temperature Range: -40°C to 105°C (exact match required)

Allowable Variation Parameters:

• ESR (Equivalent Series Resistance): May vary based on series design
• Lifetime @ Temperature: May vary; higher ratings provide extended service life
• Ripple Current Capacity: May vary; higher ratings provide additional margin
• Physical Dimensions (Diameter, Height): Minor variations permitted within mechanical compatibility constraints
• Packaging Format: Bulk or standard packaging acceptable

The substitute part 381LX821M100J012 meets all critical matching parameters and is therefore qualified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

LP821M100E1P3 Selection Criteria:

• Standard lifetime requirement of 1000 hours at 105°C
• Ripple current demands within 980 mA @ 120 Hz specification
• Space-constrained applications where 30.00 mm diameter is acceptable
• Applications where ESR specification of 300 mOhm @ 120Hz is required

381LX821M100J012 Selection Criteria:

• Extended lifetime requirement of 3000 hours at 105°C
• Higher ripple current capacity (1.4 A @ 120 Hz, 1.8 A @ 20 kHz)
• Space-constrained applications where 25.00 mm diameter provides advantage
• Applications where compact form factor is prioritized
• Applications where ESR specification is not critical

Both parts maintain Active product status and full RoHS3 compliance. Selection between these equivalents depends on specific application requirements for lifetime, ripple current handling, and physical dimensions. The 381LX821M100J012 offers superior performance in lifetime and ripple current capacity with a more compact diameter, while the LP821M100E1P3 provides a standard performance profile with specified ESR characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 381LX821M100J012 directly replace the LP821M100E1P3 in existing designs?

A: Yes. Both parts share identical capacitance (820 µF), voltage rating (100 V), tolerance (±20%), polarization (Polar), package type (Radial, Can - Snap-In), mounting type (Through Hole), and lead spacing (10.00 mm). The 381LX821M100J012 is mechanically and electrically compatible for direct substitution.

Q: What are the physical dimension differences between these parts?

A: The LP821M100E1P3 has a diameter of 30.00 mm and height of 25.00 mm. The 381LX821M100J012 has a diameter of 25.00 mm and height of 27.00 mm. The 381LX is more compact in diameter but slightly taller. Verify PCB layout clearance before substitution.

Q: Why does the 381LX821M100J012 have a longer lifetime rating?

A: The 381LX series is rated for 3000 hours at 105°C compared to 1000 hours for the LP series. This reflects different internal design characteristics and material composition within the same electrical specifications. Both are qualified for the same operating temperature range.

Q: Are there ripple current differences between these parts?

A: Yes. The LP821M100E1P3 is rated for 980 mA @ 120 Hz and 1.176 A @ 100 kHz. The 381LX821M100J012 is rated for 1.4 A @ 120 Hz and 1.8 A @ 20 kHz. The 381LX provides higher ripple current capacity across frequency ranges.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the LP821M100E1P3 and 381LX821M100J012 are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Both carry Moisture Sensitivity Level 1 (Unlimited).

Q: What is the lead spacing specification, and is it identical for both parts?

A: Both parts have a lead spacing of 10.00 mm (0.394 inches). This specification is identical and ensures compatibility with standard PCB pad layouts designed for either part.

Q: Is ESR specification available for the 381LX821M100J012?

A: ESR specification is not provided for the 381LX821M100J012. The LP821M100E1P3 specifies 300 mOhm @ 120Hz. If ESR specification is a critical design requirement, the LP821M100E1P3 is the appropriate selection.
