Substitute Part Grouping Explanation

Substitute parts for the F871DO474M330Z are identified based on strict electrical and mechanical parameter matching. The substitution logic is based on the following criteria:

Electrical Parameters (Must Match):

• Capacitance value: 0.47 µF
• Tolerance: ±20%
• AC voltage rating: 330V minimum
• Dielectric material: Polypropylene (PP), Metallized
• Application rating: X1 (EMI/RFI Suppression)

Mechanical Parameters (Must Match):

• Mounting type: Through Hole, Radial
• Lead spacing: 0.886" (22.50mm)
• Termination type: PC Pins

Environmental & Compliance (Must Maintain):

• Operating temperature range: -40°C to 110°C minimum
• RoHS3 compliance
• REACH compliance status

Substitute parts may have additional specifications (such as higher DC voltage ratings or slightly different physical dimensions) provided they do not compromise the core electrical and mechanical requirements for the intended application.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: F871DO474M330Z (KEMET)

Use the original KEMET F871DO474M330Z when:

• Exact physical dimensions are critical for PCB layout
• KEMET supply chain is preferred
• Inventory availability is confirmed

Substitute Part: B32913A3474M000 (EPCOS - TDK Electronics)

The B32913A3474M000 is electrically and functionally equivalent to the F871DO474M330Z. Both parts meet the following criteria:

• Identical capacitance (0.47 µF) and tolerance (±20%)
• Identical AC voltage rating (330V)
• Identical dielectric material (Polypropylene, Metallized)
• Identical operating temperature range (-40°C to 110°C)
• Identical mounting configuration (Through Hole, Radial)
• Identical lead spacing (22.50mm)
• Identical application rating (X1 for EMI/RFI Suppression)
• Equivalent compliance status (ROHS3 Compliant, REACH Unaffected)

Physical Dimension Consideration:

The B32913A3474M000 has slightly larger physical dimensions (0.5mm longer and 0.5mm wider) compared to the F871DO474M330Z. Both parts maintain the same seated height (18.50mm). Verify PCB layout clearances before substitution if space constraints exist.

Additional Capability:

The B32913A3474M000 includes a 760V DC voltage rating, which exceeds the AC application requirement and provides additional design margin for DC-biased or transient overvoltage conditions.

Frequently Asked Questions (FAQ)

Q: Can B32913A3474M000 be used as a direct replacement for F871DO474M330Z?

A: Yes. Both parts have identical electrical specifications (0.47 µF, ±20%, 330V AC, Polypropylene metallized dielectric, X1 rating) and identical mechanical specifications (Through Hole Radial, 22.50mm lead spacing, PC Pins). Physical dimensions differ by 0.5mm in length and width; verify PCB layout clearances.

Q: What is the significance of the 760V DC rating on the B32913A3474M000?

A: The F871DO474M330Z does not specify a DC voltage rating. The B32913A3474M000 specifies 760V DC, which provides additional design margin and may be beneficial in applications with DC bias or transient overvoltage conditions. This does not affect AC-only applications.

Q: Are the lead spacing and mounting footprint identical?

A: Yes. Both parts have 0.886" (22.50mm) lead spacing and identical seated height (0.728" / 18.50mm). PCB footprints are compatible. The B32913A3474M000 body is 0.5mm longer and 0.5mm wider; verify clearances around the component.

Q: Do both parts meet the same compliance standards?

A: Yes. Both F871DO474M330Z and B32913A3474M000 are ROHS3 Compliant and REACH Unaffected. Both are rated for -40°C to 110°C operating temperature range.

Q: What is the X1 application rating?

A: X1 rating indicates the capacitor is suitable for EMI and RFI suppression applications, which is the intended use for both parts.

Q: Are there inventory differences between the two parts?

A: Yes. F871DO474M330Z has 1,090 units in stock. B32913A3474M000 has 17,387 units in stock. The substitute part offers significantly higher availability.

Q: Can these parts be used interchangeably in existing designs?

A: Electrical interchangeability is confirmed. Mechanical interchangeability requires verification of PCB layout clearances due to the 0.5mm dimensional differences in length and width.
