505MABA04KHS Film Capacitor Equivalent & Substitute Parts

Part Overview

The 505MABA04KHS is a 5 µF film capacitor manufactured by Cornell Dubilier / Illinois Capacitor, rated for 370V DC operation with polypropylene metallized dielectric construction. This component is classified as obsolete, necessitating identification of active equivalent and substitute parts for ongoing procurement and system maintenance. The radial through-hole configuration and motor run application profile define the functional requirements for suitable alternatives.

Substitute Part Grouping Explanation

Substitute parts for the 505MABA04KHS are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents maintain identical or equivalent electrical specifications and physical dimensions, enabling direct replacement without circuit modification:

• Capacitance: 5 µF (exact match)
• Voltage Rating - DC: 370V (exact match)
• Voltage Rating - AC: 160V (exact match)
• Dielectric: Polypropylene (PP), Metallized (exact match)
• Operating Temperature: -40°C ~ 100°C (exact match)
• Lead Spacing: 1.083" (27.50mm) (exact match)
• Mounting: Through Hole Radial (exact match)

Functional Substitutes provide equivalent capacitance and dielectric material with enhanced voltage ratings, suitable for applications where higher voltage margin is acceptable:

• Capacitance: 5 µF (exact match)
• Voltage Rating - DC: 500V (higher rating)
• Voltage Rating - AC: 250V (higher rating)
• Dielectric: Polypropylene (PP), Metallized (exact match)
• Lead Spacing: 1.083" (27.50mm) (exact match)
• Mounting: Through Hole Radial (exact match)

Substitution eligibility is determined by matching capacitance value, dielectric material type, lead spacing, mounting configuration, and voltage rating compatibility (equal or higher DC voltage rating).

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalents):

The MABA044500KHL and MABA044500KHS manufactured by Nichicon are parametric equivalents to the 505MABA04KHS. Both parts maintain identical electrical specifications (5 µF, 370V DC, 160V AC, ±10% tolerance) and physical dimensions (lead spacing 1.083", radial through-hole configuration). Both are ROHS3 compliant and active products with established supply availability. Selection between these two Nichicon variants should be based on packaging requirements and internal design specifications.

For Enhanced Voltage Margin (Functional Substitute):

The B32754C2505K000 manufactured by EPCOS - TDK Electronics provides a functional substitute with elevated voltage ratings (500V DC, 250V AC) while maintaining the same 5 µF capacitance and polypropylene metallized dielectric. This part is suitable for applications where higher voltage stress margin is required or beneficial. Physical dimensions differ slightly (height 1.260" vs. 1.102" for the main part), requiring verification of available board space. Lead spacing remains compatible at 1.083" (27.50mm). This part is active with substantial inventory availability and ROHS3 compliance.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance status. The B32754C2505K000 carries REACH Unaffected certification matching the main part specification. Selection should prioritize active product status to ensure long-term supply continuity.

Frequently Asked Questions (FAQ)

Q: Can MABA044500KHL and MABA044500KHS be used interchangeably with 505MABA04KHS?

A: Yes. Both Nichicon parts are parametric equivalents with identical electrical ratings (5 µF, 370V DC, 160V AC, ±10% tolerance) and physical dimensions (lead spacing 1.083", radial configuration, 28.00mm seated height). Direct substitution is supported without circuit modification.

Q: What is the primary difference between parametric equivalents and the functional substitute?

A: Parametric equivalents (MABA044500KHL, MABA044500KHS) maintain identical voltage ratings (370V DC, 160V AC). The functional substitute (B32754C2505K000) provides higher voltage ratings (500V DC, 250V AC) with the same capacitance and dielectric material. The functional substitute is suitable when elevated voltage margin is acceptable or required.

Q: Does the B32754C2505K000 fit the same PCB footprint?

A: Lead spacing is compatible (1.083" / 27.50mm). However, the seated height differs: B32754C2505K000 measures 1.260" (32.00mm) versus 1.102" (28.00mm) for the main part. Verify available vertical clearance on the PCB before selection.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The 505MABA04KHS, MABA044500KHL, MABA044500KHS, and B32754C2505K000 are all ROHS3 compliant. The B32754C2505K000 and main part carry REACH Unaffected certification.

Q: Which substitute part offers the best supply availability?

A: The B32754C2505K000 (EPCOS - TDK Electronics) has the highest inventory level at 5889 pieces. Nichicon parametric equivalents (MABA044500KHL: 868 pcs, MABA044500KHS: 941 pcs) provide adequate availability with active product status.

Q: Can the 500V rated B32754C2505K000 be used in a 370V application?

A: Yes. Higher voltage-rated capacitors are suitable for lower voltage applications. The 500V rating provides additional stress margin. Verify that circuit design does not depend on specific voltage derating characteristics of the original 370V part.

Q: What is the operating temperature range for substitute parts?

A: Parametric equivalents (MABA044500KHL, MABA044500KHS) maintain the original range of -40°C ~ 100°C. The B32754C2505K000 extends to -40°C ~ 105°C, providing 5°C additional high-temperature margin.
