Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the R46KI322000M2K are identified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Capacitance: 0.22 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Dielectric Material: Polypropylene (PP), Metallized (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Operating Temperature Range: -40°C ~ 110°C (exact match required)
• Termination: PC Pins (exact match required)

Allowable Variation Parameters:

• Voltage Rating - DC: 560V or higher (substitutes may exceed original rating)
• Voltage Rating - AC: 275V or higher (substitutes may exceed original rating)
• Lead Spacing: 0.591" (15.00mm) or 0.630" (16.00mm) (minor variations permitted for board layout compatibility)

All identified substitutes maintain identical physical dimensions (0.709" L x 0.295" W, 18.00mm x 7.50mm) and maximum seated height (0.535" / 13.60mm), ensuring mechanical compatibility in existing PCB designs.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and full RoHS3 compliance, ensuring regulatory alignment with the original R46KI322000M2K component.

R463I322000M2K and R463I322050M2K: These substitutes feature elevated voltage ratings (630V DC / 310V AC) compared to the main part (560V DC / 275V AC). Both components are suitable for applications where higher voltage margin is required or where circuit design specifications permit higher-rated components. The R463I base product number indicates a different internal construction variant within the KEMET R46 series.

R46KI322050M2K: This substitute maintains identical voltage ratings (560V DC / 275V AC) to the main part while sharing the same R46KI base product number. The "50" designation in the part number indicates a minor specification variation. This component provides direct functional equivalence with identical electrical performance characteristics.

All substitutes maintain identical physical dimensions, lead spacing, and thermal operating range, ensuring direct mechanical and thermal compatibility in existing circuit board designs.

Frequently Asked Questions (FAQ)

Q: Can R463I322000M2K replace R46KI322000M2K in my application?

A: Yes, provided your circuit design accommodates the higher voltage rating (630V DC vs. 560V DC). The R463I322000M2K maintains all other critical parameters: 0.22 µF capacitance, ±10% tolerance, polypropylene dielectric, identical physical dimensions, and -40°C to 110°C operating range. The higher voltage rating does not degrade performance in lower-voltage applications.

Q: What is the difference between R46KI322050M2K and R46KI322000M2K?

A: Both components share identical electrical specifications (0.22 µF, ±10%, 560V DC, 275V AC) and physical dimensions. The "50" designation in R46KI322050M2K indicates a minor specification variant within the KEMET R46KI product line. Both are functionally equivalent for EMI/RFI suppression applications.

Q: Are all substitute parts mechanically compatible with the original PCB design?

A: Yes. All substitute parts maintain identical physical dimensions (18.00mm x 7.50mm), maximum seated height (13.60mm), and lead spacing (15.00mm). Direct board-level substitution is supported without PCB layout modifications.

Q: Do the substitute parts meet the same compliance standards as the main part?

A: Yes. All listed substitutes are ROHS3 compliant and maintain X2 ratings identical to the R46KI322000M2K. REACH status is consistent across all parts.

Q: Which substitute should I select if voltage margin is critical?

A: R463I322000M2K or R463I322050M2K provide 630V DC rating, offering 70V additional margin over the main part's 560V rating. Both are suitable for applications requiring enhanced voltage headroom.

Q: Can I use these substitutes interchangeably in production?

A: Yes, all listed parts are functionally equivalent within the specified parameter ranges. Selection should be based on voltage rating requirements, lead spacing compatibility, and inventory availability.
