315MABA03KHS Film Capacitor Equivalent & Substitute Parts

Part Overview

The 315MABA03KHS is a 3.15 µF film capacitor manufactured by Cornell Dubilier / Illinois Capacitor, designed for motor run applications. This radial polypropylene metallized film capacitor operates at 500V DC / 250V AC with ±10% tolerance and is rated for -40°C to 100°C operating temperature range. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain identical electrical and mechanical specifications for continued system support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 315MABA03KHS is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 3.15 µF (exact match required)
• Tolerance: ±10% (identical tolerance band)
• Voltage rating: 500V DC / 250V AC (minimum ratings must be met or exceeded)
• Dielectric material: Polypropylene (PP), Metallized (material type must match)

Mechanical Parameters:

• Mounting type: Through Hole (PCB assembly compatibility)
• Package configuration: Radial (lead orientation and spacing)
• Physical dimensions: 1.260" L x 0.591" W, height 0.965", lead spacing 1.083" (board layout fit)
• Termination: PC Pins (solder connection compatibility)

Environmental & Compliance Parameters:

• Operating temperature range: -40°C to 100°C (thermal performance envelope)
• RoHS3 compliance (regulatory requirement)

Substitute parts must demonstrate identical or superior performance across all listed parameters with no deviations in electrical ratings, physical footprint, or environmental specifications.

Parameter Comparison

Engineering Selection Recommendations

Both Nichicon substitute parts (MABA034315KHL and MABA034315KHS) are direct parametric equivalents to the obsolete 315MABA03KHS. Selection between alternatives is based on the following engineering criteria:

Product Status: The original Cornell Dubilier part is classified as obsolete. Both Nichicon alternatives maintain active product status, ensuring long-term availability and supply chain continuity for motor run applications.

Compliance Certification: All three parts maintain ROHS3 compliance, satisfying regulatory requirements for electronic component procurement and assembly.

Electrical Performance: The substitute parts deliver identical electrical specifications: 3.15 µF capacitance, ±10% tolerance, 500V DC / 250V AC voltage ratings, and polypropylene metallized dielectric material. Operating temperature range (-40°C to 100°C) is maintained across all variants.

Mechanical Compatibility: Physical dimensions, lead spacing, and radial through-hole configuration are identical across all parts, ensuring direct PCB layout compatibility without redesign or rework.

Inventory Availability: MABA034315KHL (1115 Pcs) and MABA034315KHS (781 Pcs) both demonstrate adequate stock levels for production requirements.

Frequently Asked Questions (FAQ)

Q: Can the Nichicon MABA034315KHL or MABA034315KHS be used as direct replacements for the obsolete 315MABA03KHS?

A: Yes. Both Nichicon parts are parametric equivalents meeting all electrical and mechanical specifications. Capacitance (3.15 µF), voltage ratings (500V DC / 250V AC), tolerance (±10%), dielectric material (polypropylene metallized), operating temperature range (-40°C to 100°C), physical dimensions, lead spacing, and termination type are identical. Direct substitution is supported without circuit modification or PCB redesign.

Q: What is the difference between MABA034315KHL and MABA034315KHS?

A: Both parts are electrically and mechanically identical. The difference lies in the Moisture Sensitivity Level (MSL) designation: MABA034315KHL is listed as Not Applicable, while MABA034315KHS is also listed as Not Applicable. Both parts are suitable for motor run applications with identical performance characteristics.

Q: Are the physical dimensions and lead spacing identical to the original part?

A: Yes. All substitute parts maintain the same radial package configuration with dimensions of 1.260" L x 0.591" W (32.00mm x 15.00mm), seated height of 0.965" (24.50mm), and lead spacing of 1.083" (27.50mm). No PCB layout modifications are required.

Q: Do the substitute parts meet RoHS compliance requirements?

A: Yes. Both Nichicon alternatives are ROHS3 compliant, matching the compliance status of the original 315MABA03KHS. All parts satisfy current regulatory requirements for electronic component procurement.

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

A: The operating temperature range is -40°C to 100°C for all parts, including the original and both Nichicon substitutes. Thermal performance is equivalent across all variants.

Q: Are the substitute parts suitable for motor run applications?

A: Yes. Both Nichicon parts are rated for motor run applications, identical to the original 315MABA03KHS. Electrical specifications and dielectric material (polypropylene metallized) are optimized for this application class.
