CM6460-504 Common Mode Choke Equivalent & Substitute Parts

Part Overview

The CM6460-504 is a 500 µH 2-line common mode choke manufactured by API Delevan Inc., designed for surface mount applications with a maximum current rating of 3.3A and DC resistance of 24mOhm. This component is classified as Active product status and is available in bulk packaging with 1012 pieces in stock.

Substitute parts become necessary when the primary part number experiences supply constraints, extended lead times, or when design requirements permit alternative configurations within the same electrical and mechanical specifications. The CM6460-504 has one direct equivalent substitute that maintains identical functional parameters while offering improved compliance status.

Substitute Part Grouping Explanation

Substitution eligibility for the CM6460-504 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

Inductance value: 500 µH @ 10 kHz
Current rating: 3.3A maximum
DC resistance: 24mOhm maximum

Mechanical Parameters:

Number of lines: 2
Mounting type: Surface Mount
Package configuration: Horizontal, 4 PC Pad
Physical dimensions: 0.530" L x 0.530" W (13.46mm x 13.46mm)
Maximum height: 0.300" (7.62mm)

Environmental Parameters:

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

The CM6460R-504 qualifies as a direct substitute because it maintains identical values across all electrical, mechanical, and environmental parameters listed above. Series designation differences (CM6460 versus CM6460R) reflect manufacturing or compliance variations that do not affect functional equivalence within the specified parameter set.

Engineering Selection Recommendations

CM6460-504 Selection Criteria: The CM6460-504 is suitable for applications where RoHS compliance is not a design requirement. Current inventory of 1012 pieces supports immediate procurement for standard lead-time projects.

CM6460R-504 Selection Criteria: The CM6460R-504 is the preferred selection for designs requiring ROHS3 compliance. This substitute maintains all electrical and mechanical equivalence while meeting enhanced environmental standards. Higher inventory availability (4042 pieces) provides superior supply chain flexibility and reduced procurement risk.

Compliance Consideration: The primary distinction between these parts is RoHS compliance status. The CM6460R-504 meets ROHS3 requirements, whereas the CM6460-504 does not. Both parts maintain identical REACH Unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can CM6460R-504 be used as a direct replacement for CM6460-504 in existing designs?

A: Yes. The CM6460R-504 is electrically and mechanically identical to the CM6460-504 across all specified parameters: 500 µH inductance, 3.3A current rating, 24mOhm DCR, 2-line configuration, surface mount package, and identical physical dimensions. PCB layout and circuit performance remain unchanged.

Q: What is the difference between CM6460 and CM6460R series designations?

A: Series designation differences reflect manufacturing or compliance variations. The CM6460R series incorporates ROHS3 compliance, while the CM6460 series does not. Electrical and mechanical specifications remain identical.

Q: Are there any package or footprint differences between these parts?

A: No. Both parts use identical Horizontal, 4 PC Pad package configuration with matching dimensions of 0.530" L x 0.530" W (13.46mm x 13.46mm) and maximum height of 0.300" (7.62mm). PCB footprints are interchangeable.

Q: Which part should be selected for new designs?

A: For new designs, CM6460R-504 is recommended due to ROHS3 compliance status and higher inventory availability (4042 pieces versus 1012 pieces). This selection aligns with current environmental standards and provides superior supply chain security.

Q: Do these parts have different operating temperature ranges?

A: No. Both CM6460-504 and CM6460R-504 operate across the identical temperature range of -55°C to 105°C with MSL rating of 1 (Unlimited).

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

A: Both parts carry MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
