Substitute Part Grouping Explanation

Substitute parts for the R46KN410040N2M are classified into two distinct groups based on voltage rating capability:

Group 1: Same Voltage Rating (560V DC / 275V AC) Parts R46KN410000N2M, R46KN410000P0M, R46KN410040P0M, R46KN410045N2M, and R46KN4100JHN2M maintain identical voltage specifications. These substitutes differ only in internal construction codes (suffix designations N2M versus P0M) or lead configuration variants, which do not affect electrical performance or mechanical fit. These parts are direct functional equivalents.

Group 2: Higher Voltage Rating (630V DC / 310V AC) Parts R463N410000N2M, R463N410040N2M, and R463N410050N2M operate at elevated voltage ratings while maintaining the same 1 µF capacitance, ±20% tolerance, polypropylene dielectric, radial package, physical dimensions, lead spacing, and operating temperature range. These parts belong to the R463N base series rather than R46KN. Higher voltage rating provides additional safety margin in applications where the 560V specification may be marginal.

All substitute parts share the following critical parameters with the main part:

Capacitance: 1 µF
Tolerance: ±20%
Dielectric: Polypropylene (PP), Metallized
Mounting: Through Hole Radial
Dimensions: 26.50mm × 10.00mm
Lead Spacing: 22.50mm
Temperature Range: -40°C to 110°C
Application Rating: X2
RoHS3 Compliance

Frequently Asked Questions (FAQ)

Q: Can R463N series parts (630V rating) be used in place of R46KN series parts (560V rating)? A: Yes. The R463N parts operate at higher voltage ratings while maintaining identical capacitance (1 µF), tolerance (±20%), dielectric material (polypropylene metallized), physical dimensions (26.50mm × 10.00mm), lead spacing (22.50mm), and operating temperature range (-40°C to 110°C). Higher voltage rating does not degrade performance in circuits designed for 560V operation.

Q: What is the difference between R46KN410040N2M and R46KN410000N2M? A: Both parts share identical electrical specifications (1 µF, ±20%, 560V DC, 275V AC) and mechanical properties. The difference lies in internal construction codes embedded in the part number suffix. Both are functionally equivalent for circuit applications.

Q: Are P0M and N2M suffix designations interchangeable? A: Yes. Parts designated with P0M (R46KN410000P0M, R46KN410040P0M) and N2M (R46KN410040N2M, R46KN410000N2M, R46KN410045N2M, R46KN4100JHN2M) suffixes are electrically and mechanically equivalent. Suffix variations indicate internal construction or packaging method differences that do not affect performance or fit.

Q: Will R463N410000N2M fit the same PCB footprint as R46KN410040N2M? A: Yes. Both parts share identical physical dimensions (26.50mm length × 10.00mm width), lead spacing (22.50mm), and radial through-hole mounting configuration. PCB layout compatibility is maintained.

Q: Which substitute part has the best inventory availability? A: R463N410000N2M offers the highest inventory level at 41,767 pcs. For same-voltage (560V) substitutes, R46KN410045N2M provides the largest stock at 25,399 pcs.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All substitute parts listed maintain ROHS3 compliance and REACH Unaffected status, matching the regulatory profile of the original R46KN410040N2M component.

Q: Can I use a 630V rated capacitor in a 560V circuit? A: Yes. Operating a higher-rated component in a lower-voltage application is standard engineering practice. The R463N series (630V) parts function correctly in circuits specified for 560V operation, providing additional voltage safety margin.
