Key Parameters

Substitute Part Grouping Explanation

Substitution of the 475MABA03KJS is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Capacitance value: 4.7 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating - DC: minimum 500V
• Dielectric Material: Polypropylene (PP), Metallized
• Mounting Type: Through Hole
• Package / Case: Radial
• Termination: PC Pins

Secondary Compatibility Factors:

• Operating temperature range: -40°C minimum to 100°C minimum
• Lead spacing: 1.476" (37.50mm) preferred for direct PCB compatibility
• RoHS3 compliance required for regulatory alignment

Substitute parts are classified into two categories: Parametric Equivalents (identical electrical and mechanical specifications) and Similar Substitutes (matching core parameters with acceptable voltage rating elevation).

Parameter Comparison

Engineering Selection Recommendations

Parametric Equivalents (Preferred for Direct Replacement):

MABA034470KJL and MABA034470KJS, both manufactured by Nichicon, are parametric equivalents to the 475MABA03KJS. These components match all electrical specifications (4.7 µF, ±10%, 500V DC, 250V AC) and mechanical dimensions (1.673" L x 0.669" W, 1.476" lead spacing). Both parts are ROHS3 compliant and active in production status. The distinction between KJL and KJS variants relates to packaging and internal construction specifications not affecting functional equivalence. These parts provide direct PCB compatibility without layout modifications.

Similar Substitute (Elevated Voltage Rating):

The R46KR447050M2K manufactured by KEMET is classified as a similar substitute. This component maintains identical capacitance (4.7 µF), tolerance (±10%), and dielectric material (polypropylene metallized). The voltage rating is elevated to 560V DC and 275V AC, exceeding the original 500V DC / 250V AC specification. The operating temperature range extends to 110°C, providing enhanced thermal margin. However, the lead spacing is reduced to 1.083" (27.50mm) and overall dimensions are smaller (1.260" L x 0.709" W), requiring PCB layout verification before implementation. This part is ROHS3 compliant and active in production.

Selection Basis:

For applications requiring direct drop-in replacement without PCB modification, select MABA034470KJL or MABA034470KJS. For applications where elevated voltage rating and extended temperature range provide system benefits and PCB layout permits lead spacing adjustment, R46KR447050M2K is acceptable. All substitute options maintain ROHS3 compliance and active production status, ensuring long-term availability.

Frequently Asked Questions (FAQ)

Q: Can MABA034470KJL and MABA034470KJS be used interchangeably with 475MABA03KJS?

A: Yes. Both Nichicon parts are parametric equivalents with identical electrical ratings (4.7 µF, ±10%, 500V DC, 250V AC) and mechanical dimensions (1.673" L x 0.669" W, 1.476" lead spacing). They provide direct PCB compatibility without layout modifications.

Q: What is the difference between MABA034470KJL and MABA034470KJS?

A: Both parts are functionally equivalent with identical electrical and mechanical specifications. Differences relate to internal construction and packaging designations specified by Nichicon. Selection between these variants depends on specific procurement and packaging requirements.

Q: Can R46KR447050M2K replace 475MABA03KJS directly on the PCB?

A: R46KR447050M2K requires PCB layout verification before implementation. While electrically compatible, the lead spacing is reduced from 1.476" to 1.083" (27.50mm), and physical dimensions are smaller. PCB hole spacing must accommodate the 27.50mm lead pitch. If the original PCB is designed for 37.50mm spacing, layout modification is required.

Q: Does the elevated voltage rating of R46KR447050M2K (560V DC vs. 500V DC) affect circuit operation?

A: No. The elevated voltage rating of R46KR447050M2K provides additional safety margin in the circuit. The capacitor operates at the circuit's applied voltage, not at its rated maximum. The higher rating does not alter capacitance value, tolerance, or functional performance.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The 475MABA03KJS and all identified substitutes (MABA034470KJL, MABA034470KJS, R46KR447050M2K) are ROHS3 compliant, meeting current regulatory requirements for hazardous substance restrictions.

Q: What is the lead spacing significance for PCB compatibility?

A: Lead spacing determines the distance between component pins on the PCB. The original 475MABA03KJS and Nichicon equivalents use 1.476" (37.50mm) spacing. The KEMET R46KR447050M2K uses 1.083" (27.50mm) spacing. PCB hole patterns must match the component's lead spacing for proper insertion and soldering. Mismatched spacing prevents correct component placement.

Q: Can I use R46KR447050M2K if my PCB is designed for 37.50mm lead spacing?

A: No. The R46KR447050M2K lead spacing of 27.50mm is incompatible with PCB hole patterns designed for 37.50mm spacing. Direct substitution would result in misalignment and failed assembly. Use MABA034470KJL or MABA034470KJS for PCBs with 37.50mm hole spacing.
