305MABA02KIS Film Capacitor - Equivalent & Substitute Parts

Part Overview

The 305MABA02KIS is a 3 µF polypropylene film capacitor rated for 600V DC operation, manufactured by Cornell Dubilier / Illinois Capacitor. This radial-lead component is designed for motor run applications with a metallized polypropylene dielectric. The part is currently listed with obsolete product status. Due to the discontinued classification of the primary part number, qualified substitutes provide continuity for maintenance, repair, and ongoing production requirements while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 305MABA02KIS is based on the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Capacitance value: 3 µF (exact match)
• Tolerance: ±10% (exact match)
• Dielectric material: Polypropylene (PP), Metallized
• Mounting type: Through Hole Radial configuration
• Termination: PC Pins
• Operating temperature range: Minimum -40°C to 100°C

Grouping Structure:

The substitute parts are classified into two categories based on electrical performance:

1. Parametric Equivalent (MABA024300KIL): Matches all primary electrical specifications (3 µF, ±10% tolerance, 600V DC, 320V AC) and mechanical dimensions precisely. Identical physical footprint with 35.00mm lead spacing enables direct replacement without board layout modifications.

2. Similar Manufacturer Part (B32754C4305K000): Provides enhanced voltage rating (800V DC, 400V AC) with identical capacitance and tolerance specifications. Mechanical package differs (27.50mm lead spacing, different case dimensions), requiring verification of space constraints and lead compatibility in the target application.

Parameter Comparison

Engineering Selection Recommendations

MABA024300KIL (Nichicon) is the preferred substitute for direct replacement of the 305MABA02KIS. This part maintains identical electrical specifications (3 µF, ±10%, 600V DC, 320V AC) and physical dimensions, ensuring compatibility without circuit board layout modification. Both parts are ROHS3 compliant and available in production quantities. The parametric equivalence of this part number provides maximum design certainty for maintenance and repair applications.

B32754C4305K000 (EPCOS - TDK Electronics) is suitable when circuit design permits utilization of the higher voltage rating (800V DC, 400V AC). This part provides additional safety margin in high-voltage applications but requires board-level verification due to different physical footprint (27.50mm lead spacing versus 35.00mm) and increased height (36.50mm seated height). Active product status and ROHS3 compliance confirm ongoing manufacturing support. The enhanced operating temperature range (-40°C to 105°C) supports extended operating environments.

Both substitute options are ROHS3 compliant, REACH unaffected, and EAR99 classified, supporting regulatory requirements for replacement component selection.

Frequently Asked Questions (FAQ)

Q: Can MABA024300KIL be directly substituted for 305MABA02KIS without circuit board modifications?

A: Yes. The MABA024300KIL provides identical electrical specifications and mechanical footprint, including 35.00mm lead spacing and matching physical dimensions. Direct replacement is possible without board layout changes.

Q: What are the key differences between the two substitute options?

A: The MABA024300KIL matches all specifications of the original part identically. The B32754C4305K000 offers higher voltage rating (800V DC versus 600V DC) but requires board-level verification due to different lead spacing (27.50mm versus 35.00mm) and increased seated height (36.50mm versus 26.00mm).

Q: Are both substitute parts ROHS3 compliant?

A: Yes. Both MABA024300KIL and B32754C4305K000 carry ROHS3 compliance certification, supporting regulatory requirements for electronic component selection.

Q: Does the higher voltage rating of B32754C4305K000 affect circuit performance?

A: No. The higher voltage rating provides additional electrical margin without altering the 3 µF capacitance or ±10% tolerance specifications. Circuit performance remains equivalent for applications operating at or below the original 600V DC rating.

Q: What is the lead spacing requirement for PCB layout compatibility?

A: The 305MABA02KIS and MABA024300KIL both require 35.00mm (1.378") lead spacing. The B32754C4305K000 uses 27.50mm (1.083") spacing and cannot be substituted without board modification or adapters.

Q: Are both substitute parts in active production?

A: Yes. Both MABA024300KIL (Nichicon) and B32754C4305K000 (EPCOS - TDK Electronics) carry active product status with confirmed inventory availability, ensuring long-term supply reliability for production applications.
