Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MALIEYN07LU512C02K is determined by strict equivalence in the following parameters:

• Capacitance: 12000 µF (exact match required)
• Voltage Rating: 10 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package / Case: Radial, Can - Snap-In (exact match required)
• Lead Spacing: 0.394" (10.00mm) (exact match required)
• Physical Dimensions: 0.866" Dia × 1.063" Height (exact match required)
• Mounting Type: Through Hole (exact match required)
• Polarization: Polar (exact match required)

All substitute parts listed meet these core electrical and mechanical parameters. Variations in ESR, ripple current, lifetime ratings, and operating temperature ranges are secondary considerations that do not disqualify substitution but may affect performance characteristics in specific applications.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—381LQ123M010H012, 381LX123M010H012, and B41231A3129M000—are functionally equivalent to the obsolete MALIEYN07LU512C02K based on core electrical and mechanical parameters. Selection among these alternatives should be based on the following criteria:

For applications requiring extended operational life at elevated temperatures: The 381LX123M010H012 offers 3000 hours lifetime at 105°C, compared to 2000 hours at 85°C for the original part. The 381LQ123M010H012 provides 2000 hours at 105°C, extending temperature tolerance without sacrificing rated lifetime.

For applications with strict ripple current requirements: The B41231A3129M000 and original MALIEYN07LU512C02K both support 3.31 A ripple current at 120 Hz. The CDE alternatives (381LQ123M010H012 and 381LX123M010H012) support 2.2 A ripple current, which may be limiting in high-frequency switching or high-current ripple environments.

For applications with ESR-sensitive designs: The original part specifies 44 mOhm ESR at 120 Hz. The CDE alternatives specify 76 mOhm ESR. The B41231A3129M000 does not specify ESR, requiring verification against design requirements.

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility with the original design.

Frequently Asked Questions (FAQ)

Q: Can I use 381LQ123M010H012 or 381LX123M010H012 as direct replacements for MALIEYN07LU512C02K?

A: Yes. Both CDE parts meet all core substitution criteria: 12000 µF capacitance, 10 V rating, ±20% tolerance, identical physical dimensions, lead spacing, and snap-in package configuration. They are mechanically and electrically compatible for through-hole PCB mounting.

Q: What is the difference between 381LQ123M010H012 and 381LX123M010H012?

A: Both parts are manufactured by Cornell Dubilier Electronics with identical electrical and mechanical specifications. The primary difference is lifetime rating: 381LQ123M010H012 provides 2000 hours at 105°C, while 381LX123M010H012 provides 3000 hours at 105°C. Both support operating temperatures from -40°C to 105°C.

Q: Why does B41231A3129M000 not specify ESR?

A: ESR specification is not provided in the available technical data for the EPCOS B41231A3129M000. Applications requiring specific ESR values should contact the manufacturer or consult detailed datasheets for confirmation.

Q: Are there any PCB layout considerations when substituting these parts?

A: No. All substitute parts maintain identical lead spacing (0.394" / 10.00mm), physical diameter (0.866" / 22.00mm), and height (1.063" / 27.00mm). PCB footprints and mounting holes require no modification.

Q: Which substitute part should I choose for a new design?

A: Selection depends on application requirements. For standard general-purpose filtering with moderate ripple current, any substitute is acceptable. For extended thermal operation, choose 381LX123M010H012 or 381LQ123M010H012. For applications matching the original ripple current specification (3.31 A), choose B41231A3129M000 or verify CDE ripple current tolerance.

Q: Are all substitute parts currently in stock?

A: According to available inventory data, 381LQ123M010H012 has 667 units, 381LX123M010H012 has 798 units, and B41231A3129M000 has 687 units in stock as new original components.
