Substitute Part Grouping Explanation

Substitution for the 405MABA02KHL is determined by the following critical parameters:

Parametric Equivalents (Full Compatibility): Substitute parts MABA024400KHL and MABA024400KHS from Nichicon are parametric equivalents. These parts match all essential electrical and mechanical specifications: 4 µF capacitance, ±10% tolerance, 600V DC rating, 320V AC rating, polypropylene metallized dielectric, -40°C to 100°C operating temperature, radial through-hole mounting, identical physical dimensions (1.260" L x 0.709" W, 32.00mm x 18.00mm), and 1.083" (27.50mm) lead spacing. Both parts are active products with ROHS3 compliance.

Similar Substitute (Reduced Voltage Rating): Part 953BXW4KSF-F from Cornell Dubilier Electronics (CDE) shares the same capacitance (4 µF), tolerance (±10%), dielectric material (polypropylene metallized), and mounting type (through-hole radial). However, this part has a reduced voltage rating of 275V AC with no DC rating specified, larger physical dimensions (1.634" L x 0.945" W, 41.50mm x 24.00mm), and increased lead spacing (1.476", 37.50mm). This part is suitable only for applications where the lower voltage rating is acceptable and physical space permits the larger footprint.

Engineering Selection Recommendations

Primary Substitutes (Recommended for Direct Replacement):

MABA024400KHL and MABA024400KHS from Nichicon are the preferred substitutes for the obsolete 405MABA02KHL. Both parts are active products with full parametric equivalence, matching all electrical specifications (4 µF, ±10%, 600V DC, 320V AC), identical physical dimensions, and matching lead spacing. Both are ROHS3 compliant. Selection between these two Nichicon variants should be based on availability and specific termination requirements, as both provide identical electrical and mechanical compatibility.

Secondary Substitute (Conditional Use):

The 953BXW4KSF-F from Cornell Dubilier Electronics may be used only in applications where the reduced voltage rating (275V AC) is acceptable and the larger physical footprint (1.634" L x 0.945" W) can be accommodated on the circuit board. This part is not suitable for direct replacement in circuits requiring the full 600V DC or 320V AC rating of the original component. The lower operating temperature maximum (85°C versus 100°C) must also be evaluated against application requirements.

Frequently Asked Questions (FAQ)

Q: Can MABA024400KHL and MABA024400KHS be used interchangeably with 405MABA02KHL?

A: Yes. Both Nichicon parts are parametric equivalents with identical electrical ratings (4 µF, ±10%, 600V DC, 320V AC), dielectric material (polypropylene metallized), physical dimensions (32.00mm x 18.00mm), and lead spacing (27.50mm). Both are active products with ROHS3 compliance and are suitable for direct replacement in motor run applications.

Q: Why is 953BXW4KSF-F listed as a substitute if it has a lower voltage rating?

A: The 953BXW4KSF-F shares the same capacitance, tolerance, dielectric material, and mounting type as the original part. However, its 275V AC rating (with no DC rating specified) is lower than the original 600V DC / 320V AC rating. This part is a substitute only for applications where the lower voltage specification is acceptable and physical space permits the larger 41.50mm x 24.00mm footprint.

Q: Will the larger dimensions of 953BXW4KSF-F affect circuit board layout?

A: Yes. The 953BXW4KSF-F measures 1.634" L x 0.945" W (41.50mm x 24.00mm) compared to the original 1.260" L x 0.709" W (32.00mm x 18.00mm). Additionally, the lead spacing is 1.476" (37.50mm) versus 1.083" (27.50mm). Physical board layout verification is required before selecting this part.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The 405MABA02KHL, MABA024400KHL, MABA024400KHS, and 953BXW4KSF-F are all ROHS3 compliant and REACH unaffected.

Q: What is the difference between MABA024400KHL and MABA024400KHS?

A: Both parts are Nichicon MAB series 4 µF film capacitors with identical electrical and mechanical specifications. The difference lies in the termination designation (KHL versus KHS). Selection should be based on specific termination requirements and availability from your supplier.

Q: Can 953BXW4KSF-F be used in a motor run application?

A: The original 405MABA02KHL is specified for motor run applications. The 953BXW4KSF-F is specified for EMI and RFI suppression applications. While both are polypropylene film capacitors, the application difference and reduced voltage rating indicate that 953BXW4KSF-F is not the optimal choice for motor run circuits designed for the original part's 600V DC rating.
