Substitute Part Grouping Explanation

Substitution eligibility for the CM1011-105 is determined by the following critical parameters:

Electrical Equivalence Criteria:

• Inductance value of 1 mH (measurement frequency may vary within industry tolerance)
• 2-line configuration for common mode filtering
• Current rating of 5.7A or greater
• DC resistance of 18 mOhm or less
• Operating temperature range of -55°C to 125°C or broader

Mechanical Compatibility Criteria:

• Through-hole mounting type
• Horizontal orientation, 4-pin package configuration
• Physical dimensions within 27.90mm x 27.90mm footprint tolerance
• Pin spacing compatible with standard PCB layouts

The CMF4-1004HCLF manufactured by Gowanda Electronics meets all electrical and mechanical substitution criteria for the CM1011-105.

Engineering Selection Recommendations

CM1011-105 Selection Basis: The CM1011-105 remains the primary component choice when RoHS non-compliant specifications are acceptable within the application requirements. This part is actively produced with robust inventory levels of 837 pieces.

CMF4-1004HCLF Selection Basis: The CMF4-1004HCLF serves as a direct electrical and mechanical substitute when ROHS3 compliance is required. This component maintains identical electrical performance across all critical parameters: 1 mH inductance, 5.7A current rating, and 18 mOhm DC resistance. The reduced height of 0.610" (15.49mm) compared to 0.731" (18.56mm) provides additional PCB layout flexibility. Moisture sensitivity level of 1 (Unlimited) indicates no special storage or handling requirements.

Both components are active products with confirmed inventory availability and share identical footprint dimensions and pin configurations.

Frequently Asked Questions (FAQ)

Q: Can the CMF4-1004HCLF replace the CM1011-105 in existing designs?

A: Yes. Both components share identical electrical specifications (1 mH inductance, 5.7A current rating, 18 mOhm DC resistance), identical operating temperature range (-55°C to 125°C), and identical mechanical footprint (27.90mm x 27.90mm). The CMF4-1004HCLF has a lower profile height (0.610" vs 0.731"), which may provide additional clearance in space-constrained layouts.

Q: What is the difference in inductance measurement frequency between these parts?

A: The CM1011-105 specifies inductance at 1 kHz, while the CMF4-1004HCLF specifies inductance at 10 kHz. Both deliver 1 mH inductance at their respective measurement frequencies. This difference reflects manufacturer test methodology and does not affect functional equivalence in common mode choke applications.

Q: Are there compliance differences between these substitutes?

A: Yes. The CMF4-1004HCLF is ROHS3 compliant, while the CM1011-105 is RoHS non-compliant. The CMF4-1004HCLF has a moisture sensitivity level of 1 (Unlimited), indicating no special moisture control requirements during storage or handling.

Q: Do these components have identical pin configurations?

A: Yes. Both the CM1011-105 and CMF4-1004HCLF use horizontal, 4-pin package configurations with identical footprints of 27.90mm x 27.90mm, ensuring direct PCB compatibility.

Q: Which part should be selected for new designs?

A: Selection depends on compliance requirements. For applications requiring ROHS3 compliance, specify the CMF4-1004HCLF. For applications without RoHS requirements, either component is acceptable based on availability and supply chain considerations.
