155MABA02KHS Film Capacitor Equivalent & Substitute Parts

Part Overview

The 155MABA02KHS is a 1.5 µF film capacitor rated for 600V DC operation with polypropylene metallized dielectric. Manufactured by Cornell Dubilier / Illinois Capacitor in the MAB series, this component is designed for motor run applications with ±10% capacitance tolerance and through-hole radial mounting. The part is currently obsolete, requiring identification of equivalent and substitute components for ongoing system support and new design implementations. Substitute parts must maintain electrical and mechanical compatibility within specified parameters while meeting current product availability requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 155MABA02KHS are classified based on strict adherence to the following critical electrical and mechanical parameters:

Core Electrical Parameters (Non-Negotiable):

• Capacitance Value: 1.5 µF (exact match required)
• DC Voltage Rating: minimum 600V
• AC Voltage Rating: minimum 320V
• Dielectric Material: Polypropylene (PP), Metallized
• Mounting Configuration: Through-hole Radial

Mechanical Compatibility Parameters:

• Lead Spacing: 1.083" (27.50 mm) nominal
• Package Type: Radial configuration
• Termination: PC Pins
• Overall dimensions permitting board-level installation without design modification

Acceptable Variance Parameters:

• Capacitance Tolerance: ±10% or tighter (±5% acceptable)
• Operating Temperature Range: may extend beyond original range
• Product Status: Active or Obsolete (availability dependent)
• Certification Compliance: ROHS3 Compliant minimum

The substitution logic identifies parts meeting all core electrical parameters and mechanical compatibility criteria. Secondary performance enhancements (improved tolerance, extended temperature range, additional certifications) may be present in active substitute parts.

Engineering Selection Recommendations

MABA024150KHL (Nichicon) - Parametric Equivalent

This part represents the closest parametric equivalent to the 155MABA02KHS. It matches all core electrical specifications (1.5 µF, 600V DC, 320V AC, ±10% tolerance) and maintains identical mechanical dimensions and lead spacing. The part is currently Active in product status with ROHS3 compliance. No design modifications are required for direct substitution in applications originally specified for 155MABA02KHS.

R76PR415050H3J (KEMET) - Compatible Substitute

This part meets core electrical requirements with equal capacitance and exceeds voltage ratings (630V DC, 400V AC). It features improved tolerance specification (±5%) and extended operating temperature range (-55°C to +125°C), with ROHS3 and AEC-Q200 compliance. The maximum seated height exceeds the original specification (1.461" vs. 0.866"), requiring physical space verification on target PCB layout. Lead spacing matches at 1.083" (27.50 mm). The part is currently Active with broader application range including automotive and high-frequency circuits.

Both substitutes are ROHS3 compliant and currently available. Selection between them depends on physical space constraints and extended performance requirements. The Nichicon option provides direct dimensional compatibility, while the KEMET option offers enhanced specifications at the cost of increased board footprint height.

Frequently Asked Questions (FAQ)

Q: Can R76PR415050H3J be used as a direct replacement for 155MABA02KHS?

A: R76PR415050H3J meets all core electrical requirements with matching lead spacing (27.50 mm). However, the maximum seated height is 1.461" compared to the original 0.866". Board layout verification is required to confirm clearance above the PCB. Electrical performance is fully compatible.

Q: Is MABA024150KHL a direct substitute without design modification?

A: Yes. MABA024150KHL matches all electrical and mechanical specifications of 155MABA02KHS, including identical capacitance, voltage ratings, tolerance, operating temperature range, and physical dimensions. No design modifications are required.

Q: What is the difference between the two substitute parts?

A: MABA024150KHL provides parametric equivalence with identical dimensions and specifications. R76PR415050H3J offers enhanced electrical performance (±5% tolerance, higher voltage ratings, extended temperature range, AEC-Q200 automotive compliance) but requires larger board space (37.10 mm height vs. 22.00 mm).

Q: Are both substitute parts RoHS compliant?

A: Yes. Both MABA024150KHL and R76PR415050H3J are ROHS3 Compliant, meeting environmental compliance requirements equivalent to the original part.

Q: Which substitute is recommended for new designs?

A: Selection depends on application requirements. For motor run applications with space constraints, MABA024150KHL provides direct parametric equivalence. For automotive or high-frequency applications requiring extended performance specifications, R76PR415050H3J is appropriate if board space permits the 37.10 mm seated height.

Q: Can these parts be used in applications beyond motor run circuits?

A: Both parts support motor run applications. R76PR415050H3J carries automotive qualification (AEC-Q200) and supports high-frequency switching and high pulse DV/DT applications. MABA024150KHL specifications align with motor run circuit requirements.
