CM6460R-754 Equivalent & Substitute Parts

Part Overview

The CM6460R-754 is a 750 µH 2-line common mode choke (CMC) in surface mount configuration, manufactured by API Delevan Inc. This component is designed for electromagnetic interference (EMI) filtering applications requiring dual-line filtering with a maximum current rating of 2.7A and DC resistance of 35mOhm. The part is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical performance can be maintained within the specified parameter tolerances while accommodating different application constraints such as increased current capacity or modified package dimensions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CM6460R-754 is determined by the following critical parameters:

Core Electrical Parameters (Must Match):

• Inductance value: 750 µH @ 10 kHz
• Number of lines: 2-line configuration
• Mounting type: Surface Mount
• Operating temperature range: -55°C to 105°C
• Compliance certifications: RoHS3, REACH Unaffected, EAR99

Allowable Variation Parameters:

• Current rating: May exceed the 2.7A specification of the main part
• DC resistance: May be lower than 35mOhm maximum
• Package dimensions: May differ while maintaining 4 PC Pad horizontal configuration
• Inventory status: Independent of substitution eligibility

The CM6560R-754 qualifies as a parametric equivalent because it maintains identical inductance, line count, temperature range, and compliance status while providing enhanced current capacity (3A vs. 2.7A) and marginally improved DC resistance (34mOhm vs. 35mOhm). The larger package footprint (16.00mm x 16.00mm vs. 13.46mm x 13.46mm) represents a physical trade-off that may require PCB layout verification.

Parameter Comparison

Engineering Selection Recommendations

CM6460R-754 Selection Criteria:

• Applications with space constraints requiring compact 13.46mm x 13.46mm footprint
• Designs where maximum current demand does not exceed 2.7A
• PCB layouts with height limitations below 7.62mm
• Existing designs with validated CM6460R-754 performance

CM6560R-754 Selection Criteria:

• Applications requiring current capacity up to 3.0A
• Designs where slightly improved DC resistance (34mOhm) provides thermal or efficiency benefits
• PCB layouts accommodating 16.00mm x 16.00mm footprint and 8.13mm height
• New designs where enhanced current margin provides design flexibility

Both parts maintain identical RoHS3 compliance, REACH unaffected status, and EAR99 export classification. Both are manufactured by API Delevan Inc. and carry active product status with unlimited moisture sensitivity rating. Selection between these parts depends solely on application current requirements and available PCB real estate.

Frequently Asked Questions (FAQ)

Q: Can CM6560R-754 be used as a direct replacement for CM6460R-754 in existing designs?

A: Electrical substitution is valid because inductance, line count, temperature range, and compliance certifications are identical. However, physical substitution requires PCB layout verification. The CM6560R-754 requires 2.54mm additional length, 2.54mm additional width, and 0.51mm additional height. Verify that the larger footprint (16.00mm x 16.00mm vs. 13.46mm x 13.46mm) and increased height (8.13mm vs. 7.62mm) do not conflict with component placement, trace routing, or clearance requirements.

Q: What is the significance of the current rating difference between these parts?

A: The CM6460R-754 is rated for maximum 2.7A continuous current, while the CM6560R-754 is rated for 3.0A. If your application requires current above 2.7A, the CM6460R-754 cannot be used. The CM6560R-754 provides 0.3A additional capacity. If your application operates below 2.7A, both parts are electrically equivalent for current handling.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical RoHS3 compliance, REACH unaffected status, MSL 1 (unlimited) moisture sensitivity rating, and EAR99 export classification. Both are manufactured by API Delevan Inc. and maintain active product status.

Q: What does the identical 750 µH inductance specification mean for substitution?

A: The 750 µH inductance value measured at 10 kHz is the primary filtering characteristic. Identical inductance ensures equivalent EMI filtering performance in the target frequency range. This parameter is non-negotiable for substitution eligibility.

Q: How does the DC resistance difference affect circuit performance?

A: The CM6560R-754 has 34mOhm maximum DCR compared to 35mOhm for the CM6460R-754. This 1mOhm difference is negligible for most applications. At 2.7A, the voltage drop difference is approximately 27µV, which is insignificant in typical EMI filter circuits. The lower DCR of the substitute part provides marginal thermal benefit.

Q: Can I use CM6460R-754 in place of CM6560R-754?

A: Electrical substitution is not recommended. The CM6460R-754 has lower current rating (2.7A vs. 3.0A) and larger DC resistance (35mOhm vs. 34mOhm). If the original design specified CM6560R-754, it likely requires the higher current capacity. Using the lower-rated part may result in thermal stress or performance degradation.
