CM6350-473 Equivalent & Substitute Parts

Part Overview

The CM6350-473 is a 47 µH @ 10 kHz, 2-line common mode choke for surface mount applications, rated for 5A maximum current with 8mOhm DC resistance. This component is designed for power line filtering and EMI suppression in two-line configurations. The part is Active in product status and RoHS non-compliant. Substitute parts may be required for applications demanding RoHS3 compliance, higher current ratings, or alternative inductance specifications while maintaining the same mechanical footprint and mounting characteristics.

Substitute Part Grouping Explanation

Substitution for the CM6350-473 is determined by matching the following critical parameters:

Primary Substitution Criteria:

Inductance specification (47 µH @ 10 kHz)
Number of lines (2-line configuration)
Maximum current rating (equal to or greater than 5A)
DC resistance (equal to or less than 8mOhm)
Mechanical footprint (0.360" x 0.360" x 0.210" max)
Mounting type (Surface Mount, Horizontal, 4 PC Pad)
Operating temperature range (-55°C ~ 105°C)

Secondary Substitution Criteria:

RoHS compliance status (where application requirements permit upgrades to RoHS3)
Packaging compatibility (Bulk)

The CM6350R-473 serves as a direct substitute with identical electrical and mechanical specifications but with RoHS3 compliance. The CM6350R-333 functions as a parametric equivalent with lower inductance (33 µH), higher current capacity (5.5A), and reduced DC resistance (7mOhm), suitable for applications where inductance reduction and improved current handling are acceptable trade-offs.

Engineering Selection Recommendations

CM6350R-473: Select this part for direct replacement of the CM6350-473 when RoHS3 compliance is required by application standards or procurement specifications. This substitute maintains all electrical and mechanical specifications while meeting RoHS3 environmental requirements. The CM6350R-473 is available with higher inventory (1477 Pcs) compared to the original part (979 Pcs), providing improved supply availability.

CM6350R-333: Select this part where the application permits a 30% reduction in inductance (from 47 µH to 33 µH) and can benefit from improved current margin (5.5A versus 5A) and lower DC resistance (7mOhm versus 8mOhm). This parametric equivalent is suitable for designs where the lower inductance does not compromise filtering performance and where enhanced current capacity provides design margin. The CM6350R-333 is also RoHS3 compliant and offers strong supply availability (1457 Pcs).

Frequently Asked Questions (FAQ)

Q: Can CM6350R-473 be used directly in place of CM6350-473?

A: Yes. The CM6350R-473 provides identical electrical specifications (47 µH @ 10 kHz, 5A, 8mOhm DCR) and mechanical compatibility (same footprint, height, and mounting configuration). The primary difference is RoHS3 compliance. Direct PCB layout compatibility is maintained.

Q: When should CM6350R-333 be used instead of the direct substitute?

A: Use CM6350R-333 when the application circuit design accommodates a lower inductance value (33 µH instead of 47 µH) and when the increased current rating (5.5A) provides beneficial design margin. Circuit simulation or design analysis is necessary to confirm that the reduced inductance does not degrade filtering performance in the target application.

Q: Are all three parts pin-compatible?

A: Yes. All three parts share identical mounting type (Surface Mount), package configuration (Horizontal, 4 PC Pad), and footprint dimensions (0.360" x 0.360" x 0.210" max). No PCB redesign is required for substitution.

Q: What is the impact of RoHS3 compliance on electrical performance?

A: RoHS3 compliance affects material composition but does not alter the specified electrical parameters. The CM6350R series maintains identical inductance, current rating, and DC resistance specifications as the non-compliant CM6350-473.

Q: Are there moisture sensitivity concerns with these parts?

A: All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity precautions are required during storage or handling. Standard component handling practices apply.

Q: What is the operating temperature compatibility across all three parts?

A: All three parts are rated for identical operating temperature range of -55°C to 105°C, ensuring thermal compatibility in equivalent operating environments.
