Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 805MABA03KJS are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

Electrical Parameters (Must Match):

• Capacitance: 8 µF
• Tolerance: ±10%
• Voltage Rating - DC: 500V
• Voltage Rating - AC: 250V
• Dielectric Material: Polypropylene (PP), Metallized

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole
• Package / Case: Radial
• Lead Spacing: 1.476" (37.50mm)
• Termination: PC Pins

Compliance Parameters (Must Match):

• RoHS3 Compliant

Substitute parts are grouped into two categories: Similar Manufacturer Parts (alternative sources with equivalent specifications) and Parametric Equivalents (parts from different manufacturers with identical electrical and mechanical characteristics).

Parameter Comparison

Engineering Selection Recommendations

Parametric Equivalents - Nichicon MABA034800KJL and MABA034800KJS:

The Nichicon parts MABA034800KJL and MABA034800KJS are parametric equivalents to the 805MABA03KJS. Both components share identical electrical specifications (8 µF, ±10%, 500V DC, 250V AC), dielectric material (polypropylene metallized), physical dimensions (1.673" L x 0.866" W, 42.50mm x 22.00mm), and lead spacing (1.476" / 37.50mm). Both are active products with ROHS3 compliance and are suitable for direct replacement in motor run applications. The Nichicon parts maintain the same operating temperature range (-40°C ~ 100°C) and mounting configuration as the original component.

Similar Manufacturer Part - EPCOS B32756C2805K000:

The EPCOS B32756C2805K000 is a similar manufacturer part that meets all critical electrical parameters (8 µF, ±10%, 500V DC, 250V AC) and maintains the same lead spacing (1.476" / 37.50mm) and through-hole radial mounting configuration. This part features an extended operating temperature range (-40°C ~ 105°C) and is an active product with ROHS3 compliance. Physical dimensions differ slightly: the EPCOS part measures 1.654" L x 0.709" W (42.00mm x 18.00mm) with a maximum seated height of 1.280" (32.50mm), compared to the original 1.673" L x 0.866" W with 1.181" maximum height. These dimensional differences require verification of available board space and component clearance in the target application.

Product Status Consideration:

The original 805MABA03KJS is obsolete. All three substitute parts are active products with current manufacturing support and availability, ensuring long-term supply chain reliability for new production and field replacement scenarios.

Frequently Asked Questions (FAQ)

Q: Can the Nichicon MABA034800KJL and MABA034800KJS be used interchangeably with the 805MABA03KJS?

A: Yes. Both Nichicon parts are parametric equivalents with identical capacitance (8 µF), tolerance (±10%), voltage ratings (500V DC / 250V AC), dielectric material (polypropylene metallized), physical dimensions (1.673" L x 0.866" W), lead spacing (1.476"), and operating temperature range (-40°C ~ 100°C). Direct substitution is supported for motor run applications.

Q: What are the dimensional differences between the EPCOS B32756C2805K000 and the original 805MABA03KJS?

A: The EPCOS part is narrower (0.709" W vs. 0.866" W) and taller (1.280" height vs. 1.181" height). The length is slightly shorter (1.654" vs. 1.673"). Lead spacing remains identical at 1.476". These differences require verification of available PCB space and component clearance before substitution.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The Nichicon MABA034800KJL, Nichicon MABA034800KJS, and EPCOS B32756C2805K000 are all ROHS3 compliant, matching the compliance status of the original 805MABA03KJS.

Q: What is the operating temperature difference between the EPCOS part and the original?

A: The EPCOS B32756C2805K000 operates from -40°C to 105°C, while the original 805MABA03KJS and Nichicon equivalents operate from -40°C to 100°C. The EPCOS part provides a 5°C higher maximum operating temperature.

Q: Are the lead spacing and termination type identical across all parts?

A: Yes. All substitute parts maintain the same lead spacing (1.476" / 37.50mm) and PC pin termination as the original 805MABA03KJS, ensuring compatibility with existing PCB layouts designed for through-hole radial mounting.

Q: Which substitute part is recommended for direct replacement without PCB modification?

A: The Nichicon MABA034800KJL and MABA034800KJS are recommended for direct replacement without PCB modification, as they maintain identical physical dimensions and all electrical specifications of the original 805MABA03KJS.
