226MABA03KJS Film Capacitor - Equivalent & Substitute Parts

Part Overview

The 226MABA03KJS is a 22 µF film capacitor rated for 500VDC operation, manufactured by Cornell Dubilier / Illinois Capacitor. This polypropylene metallized radial capacitor is designed for motor run applications with an operating temperature range of -40°C to 100°C. The product is classified as obsolete, making identification of functional equivalent parts essential for design continuity and component availability in production environments.

Key Parameters

Substitute Part Grouping Explanation

Equivalent substitutes for the 226MABA03KJS are identified through matching of critical electrical and mechanical parameters:

Critical matching parameters:

• Capacitance value: 22 µF (±10% tolerance)
• Voltage ratings: 500VDC / 250VAC minimum
• Dielectric material: Polypropylene (PP), metallized
• Package type: Radial through-hole
• Physical dimensions: 42.50mm L × 30.00mm W with 37.50mm lead spacing
• Termination: PC pins
• Operating temperature: -40°C to 100°C

The substitutes are organized into two categories:

Parametric Equivalents match all critical electrical parameters and physical footprint dimensions, ensuring direct interchange capability without design modifications.

Similar Manufacturer Parts share the capacitance, tolerance, and dielectric material but may differ in voltage rating, physical size, lead count, or operating temperature range, requiring design review before implementation.

Parameter Comparison

Engineering Selection Recommendations

Parametric Equivalents - Primary Selection:

MABA035220KJL and MABA035220KJS (both Nichicon) are the preferred substitutes for the obsolete 226MABA03KJS. Both parts satisfy all critical electrical and mechanical parameters with identical package footprints and physical dimensions. Both manufacturers' parts are active products with ROHS3 compliance and full operational temperature range matching (-40°C to 100°C). These parts enable direct circuit board interchange without design modification or PCB layout changes. Nichicon parts offer superior availability with 720 and 1133 units respectively in stock.

Alternative Substitute - Design Review Required:

953BQW22KSF-F (Cornell Dubilier Electronics) matches capacitance, tolerance, and dielectric material with equivalent voltage and temperature specifications for most applications. However, this part features different physical dimensions (57.50mm × 35.00mm vs. 42.50mm × 30.00mm), increased height (51.00mm vs. 45.00mm), wider lead spacing (52.50mm vs. 37.50mm), and four leads versus two leads. Implementation of this substitute requires PCB layout revision and mechanical clearance validation. The reduced maximum operating temperature (85°C vs. 100°C) must be evaluated against application thermal requirements. This substitute is suitable only when design flexibility exists for physical package changes.

Frequently Asked Questions (FAQ)

Q: Can MABA035220KJL or MABA035220KJS be used as direct replacements without PCB modification?

A: Yes. Both Nichicon parametric equivalents maintain identical physical dimensions (42.50mm × 30.00mm), height (45.00mm), and lead spacing (37.50mm) as the original 226MABA03KJS. Direct component substitution on existing PCBs is possible without layout changes.

Q: What is the key difference between the parametric equivalents from Nichicon?

A: MABA035220KJL and MABA035220KJS are both Nichicon MAB series film capacitors with identical electrical specifications and package dimensions. The selection between these two parts depends on packaging format availability and procurement requirements, as both are ROHS3 compliant active products.

Q: Why is 953BQW22KSF-F listed as a substitute if it has different dimensions?

A: 953BQW22KSF-F matches the core electrical parameters (capacitance, tolerance, dielectric material, and voltage rating) but requires design review due to package differences. This substitute is included for applications where physical size constraints are flexible or where the larger package offers manufacturing or thermal management benefits.

Q: Are there temperature rating differences between substitutes?

A: The parametric equivalents (Nichicon parts) maintain the full operating range of -40°C to 100°C. The 953BQW22KSF-F has a reduced maximum temperature rating of 85°C. Applications operating above 85°C require selection of the Nichicon parametric equivalents.

Q: Do all substitutes comply with RoHS regulations?

A: Yes. All listed substitutes—MABA035220KJL, MABA035220KJS, and 953BQW22KSF-F—are ROHS3 compliant, satisfying environmental and regulatory requirements equivalent to the original part.

Q: How do lead count differences affect circuit compatibility?

A: The main part and parametric equivalents are two-lead radial designs suitable for standard through-hole PCB applications. The 953BQW22KSF-F features four leads, which may require PCB routing adjustments or modified footprint patterns. Lead count and spacing compatibility must be verified before implementation.

Q: What inventory considerations apply to these substitutes?

A: MABA035220KJS offers the highest stock availability (1133 units), followed by 953BQW22KSF-F (973 units) and MABA035220KJL (720 units). For production continuity with the obsolete 226MABA03KJS (778 units remaining), the Nichicon parametric equivalents are recommended as primary alternatives given their immediate availability and full compatibility.
