Substitute Part Grouping Explanation

Substitute parts for the R46KF247040N0M are identified within the KEMET R46 series based on the following substitution criteria:

Primary Matching Parameters:

• Capacitance value: 0.047 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Dielectric material: Polypropylene (PP), Metallized (exact match required)
• Mounting type: Through Hole Radial (exact match required)
• Physical dimensions: 0.512" L x 0.197" W with 0.394" lead spacing (exact match required)
• Termination: PC Pins (exact match required)
• Operating temperature range: -40°C ~ 110°C (exact match required)

Allowable Variation Parameter:

• Voltage rating: DC voltage may be equal or higher; AC voltage may be equal or higher

Substitutes are grouped into two categories: direct equivalents with identical voltage ratings and parametric equivalents with higher voltage ratings that maintain all other electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

R46KF247040N0M (Main Part): Select this part number when the circuit design specifies 560V DC / 275V AC operation. All three parts maintain Active product status and ROHS3 compliance, ensuring regulatory conformance for current manufacturing standards.

R463F247040N0M (Parametric Equivalent - Higher Voltage Rating): This substitute provides 630V DC / 310V AC rating while maintaining identical capacitance, tolerance, physical dimensions, and mounting configuration. Selection is appropriate when higher voltage margin is required or when circuit voltage specifications exceed 560V DC. The increased voltage rating does not affect form factor or PCB compatibility.

R46KF247000N0M (Direct Equivalent - Identical Voltage Rating): This substitute matches the main part across all electrical and mechanical parameters, including 560V DC / 275V AC rating. Selection is appropriate for direct replacement in existing designs or when voltage specifications are identical to the original circuit requirement.

All three parts are Active products with ROHS3 compliance and REACH Unaffected status, supporting equivalent regulatory and environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can R463F247040N0M replace R46KF247040N0M in a 560V DC circuit?

A: Yes. The R463F247040N0M is rated for 630V DC, which exceeds the 560V DC requirement. Higher voltage rating does not degrade performance in lower voltage applications. All other electrical and mechanical parameters are identical.

Q: Are the physical dimensions identical across all three parts?

A: Yes. All three parts share identical dimensions of 0.512" L x 0.197" W (13.00mm x 5.00mm) with 0.394" (10.00mm) lead spacing and 0.437" (11.10mm) maximum seated height. PCB footprints and mounting holes are interchangeable.

Q: What is the difference between R46KF247040N0M and R46KF247000N0M?

A: Both parts are identical in capacitance (0.047 µF), tolerance (±20%), voltage rating (560V DC / 275V AC), and all mechanical specifications. The difference lies in the base product number designation (R46KF vs. R46KF), which reflects internal KEMET manufacturing or packaging variations. Electrical performance and substitution compatibility are equivalent.

Q: Are all three parts suitable for EMI and RFI suppression applications?

A: Yes. All three parts carry X2 ratings and are specified for EMI and RFI suppression. Capacitance, tolerance, and dielectric material are identical across all variants.

Q: Do these parts require any special handling or storage considerations?

A: Moisture Sensitivity Level (MSL) is Not Applicable for all three parts, indicating standard handling and storage conditions are sufficient. No special desiccant or controlled environment storage is required.

Q: Can I use R46KF247000N0M as a substitute if R46KF247040N0M is unavailable?

A: Yes. R46KF247000N0M is a direct equivalent with identical electrical ratings and mechanical specifications. Substitution is valid for direct component replacement without circuit redesign.
