Parameter Comparison

Engineering Selection Recommendations

Both Nichicon substitute parts (MABA024400KJL and MABA024400KJS) provide direct parametric equivalence to the obsolete Cornell Dubilier 405MABA02KJS across all electrical, mechanical, and environmental specifications. The primary distinction between the two Nichicon alternatives is product status classification; both are currently active in production.

Selection Basis:

The substitution is valid based on:

• Identical capacitance, voltage ratings, and tolerance specifications
• Matching dielectric material composition and metallization technology
• Equivalent physical dimensions and lead spacing for PCB compatibility
• Identical operating temperature range and thermal performance envelope
• Equivalent RoHS3 compliance and regulatory classification (ECCN: EAR99, HTSUS: 8532.25.0070)
• Confirmed through-hole radial package compatibility with existing circuit board layouts

Both Nichicon parts are suitable for direct replacement in motor run applications where the original 405MABA02KJS was specified.

Frequently Asked Questions (FAQ)

Q: Can MABA024400KJL and MABA024400KJS be used interchangeably with 405MABA02KJS?

A: Yes. Both Nichicon parts meet all parametric requirements for direct substitution. They share identical electrical ratings (4 µF, 600V DC, 320V AC, ±10% tolerance), dielectric composition (polypropylene metallized), physical dimensions (42.50mm × 17.00mm, 28.00mm height), lead spacing (37.50mm), and operating temperature range (-40°C to 100°C). All three parts are ROHS3 compliant and rated for motor run applications.

Q: What is the difference between MABA024400KJL and MABA024400KJS?

A: Both parts are electrically and mechanically identical. The difference is in product status: MABA024400KJL and MABA024400KJS are both active production parts from Nichicon. Selection between them should be based on availability and supply chain requirements.

Q: Will these substitute parts fit existing PCB layouts designed for 405MABA02KJS?

A: Yes. The substitute parts maintain identical physical dimensions (42.50mm length, 17.00mm width, 28.00mm seated height) and lead spacing (37.50mm). They are packaged as through-hole radial components with PC pin termination, ensuring direct compatibility with existing circuit board designs.

Q: Are there any compliance or regulatory differences between the original and substitute parts?

A: No. All three parts share identical compliance classifications: ROHS3 compliant, ECCN EAR99, and HTSUS code 8532.25.0070. There are no regulatory barriers to substitution.

Q: What is the operating temperature range for these capacitors?

A: All three parts operate across the identical temperature range of -40°C to 100°C, ensuring equivalent thermal performance in motor run applications.
