CM6350-474 Common Mode Choke Equivalent & Substitute Parts

Part Overview

The CM6350-474 is a 470 µH, 2-line common mode choke designed for surface mount applications in power line filtering. Manufactured by API Delevan Inc., this component operates at 1.5A maximum current with 60mOhm DC resistance and is rated for -55°C to 105°C operating temperature range. The part is currently active in production with 653 pieces available in stock.

Identifying equivalent and substitute parts becomes necessary when the primary part number is unavailable, when supply chain constraints occur, or when design revisions require components with improved compliance status. The CM6350-474 is RoHS non-compliant, making substitutes with updated compliance certifications valuable for new designs and manufacturing environments with stricter regulatory requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CM6350-474 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following categories:

Electrical Parameters:

• Inductance value: 470 µH @ 10 kHz
• Current rating: 1.5A maximum
• DC resistance: 60mOhm maximum
• Number of lines: 2-line configuration
• Filter type: Power line

Mechanical Parameters:

• Mounting type: Surface mount
• Package dimensions: 0.360" L x 0.360" W (9.14mm x 9.14mm)
• Maximum height: 0.210" (5.33mm)
• Package configuration: Horizontal, 4 PC Pad

Environmental Parameters:

• Operating temperature range: -55°C ~ 105°C
• Moisture sensitivity level: 1 (Unlimited)

The CM6350R-474 meets all these criteria and qualifies as a direct substitute based on parameter equivalence.

Engineering Selection Recommendations

Primary Part: CM6350-474

The CM6350-474 remains suitable for applications where RoHS non-compliance is acceptable and legacy component specifications are required. This part is active in production with adequate stock availability.

Substitute Part: CM6350R-474

The CM6350R-474 is the direct electrical and mechanical equivalent of the CM6350-474 with the following distinctions:

1. Compliance Status: The CM6350R-474 is ROHS3 compliant, whereas the CM6350-474 is RoHS non-compliant. This makes the CM6350R-474 the preferred choice for new designs, manufacturing environments subject to RoHS regulations, and applications requiring compliance documentation.

2. Inventory Availability: The CM6350R-474 has significantly higher stock availability (2437 pieces versus 653 pieces), reducing lead time risk and supply chain uncertainty.

3. Electrical and Mechanical Equivalence: All critical parameters—inductance, current rating, DC resistance, dimensions, package configuration, and operating temperature range—are identical between both parts.

4. Series Relationship: Both parts belong to the CM6350 family from API Delevan Inc., confirming design continuity and manufacturing consistency.

For new designs and procurement cycles, the CM6350R-474 is the recommended selection based on improved compliance status and superior inventory position. For existing designs locked to the CM6350-474, the CM6350R-474 provides a direct substitution path without circuit redesign or performance compromise.

Frequently Asked Questions (FAQ)

Q: Can the CM6350R-474 be used as a direct replacement for the CM6350-474 in existing designs?

A: Yes. The CM6350R-474 is electrically and mechanically identical to the CM6350-474. All critical parameters—inductance (470 µH @ 10 kHz), current rating (1.5A), DC resistance (60mOhm), dimensions (0.360" x 0.360" x 0.210"), and operating temperature range (-55°C to 105°C)—are equivalent. No circuit modifications are required.

Q: What is the primary difference between these two parts?

A: The CM6350R-474 is ROHS3 compliant, while the CM6350-474 is RoHS non-compliant. Both parts are otherwise identical in electrical performance and mechanical specifications. The CM6350R-474 also has higher inventory availability.

Q: Are the package dimensions and mounting footprints identical?

A: Yes. Both parts use the same surface mount package: Horizontal, 4 PC Pad configuration with dimensions of 0.360" L x 0.360" W (9.14mm x 9.14mm) and maximum height of 0.210" (5.33mm). PCB layouts and assembly processes require no modification.

Q: Which part should be specified for new product designs?

A: The CM6350R-474 is recommended for new designs due to ROHS3 compliance and higher stock availability. This part meets current regulatory requirements and reduces supply chain risk.

Q: Are both parts manufactured by the same company?

A: Yes. Both the CM6350-474 and CM6350R-474 are manufactured by API Delevan Inc. and are both active in production.

Q: What is the moisture sensitivity level for both parts?

A: Both parts have Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life and no special moisture control requirements during storage or handling.

Q: Can these parts be used interchangeably in power line filtering applications?

A: Yes. Both parts are classified as power line filter components with identical 2-line common mode choke specifications. They are functionally interchangeable in all power line filtering applications within the specified current and temperature ratings.
