CM6350-683 Equivalent & Substitute Parts

Part Overview

The CM6350-683 is a 68 µH, 2-line common mode choke (CMC) for surface mount applications, rated at 4.2A maximum current with 10mOhm DC resistance. Designed for power line filtering in EMI suppression circuits, this component operates across the temperature range of -55°C to 105°C. The part is currently active in production and available in bulk packaging.

Substitute parts may be required due to packaging format availability, compliance requirements, or parametric optimization for specific circuit conditions while maintaining functional compatibility within the CM6350 series.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the CM6350 series is determined by the following critical parameters:

Direct Substitutes (Identical Electrical & Mechanical Specifications):

• Inductance value: 68 µH @ 10 kHz
• Current rating: 4.2A
• DC resistance: 10mOhm maximum
• Physical footprint: 0.360" x 0.360" x 0.210" (9.14mm x 9.14mm x 5.33mm)
• Package configuration: Horizontal, 4 PC Pad

Parametric Equivalents (Different Electrical Specifications):

• Same physical footprint and mounting type
• Different inductance and current ratings
• Suitable for applications with relaxed inductance requirements or higher current capacity

Parameter Comparison

Engineering Selection Recommendations

CM6350R-683 (Direct Substitute): This part is electrically and mechanically identical to the CM6350-683, differing only in packaging format (Tape & Reel vs. Bulk) and compliance status. CM6350R-683 is ROHS3 compliant, making it suitable for applications requiring RoHS certification. Select this substitute when tape and reel packaging is required for automated assembly or when RoHS3 compliance is mandatory.

CM6350R-473 (Parametric Equivalent): This part maintains identical physical dimensions and mounting characteristics but offers reduced inductance (47 µH vs. 68 µH) and increased current capacity (5A vs. 4.2A) with lower DC resistance (8mOhm vs. 10mOhm). Select this substitute only when circuit design permits lower inductance values and higher current handling is beneficial. This part is also ROHS3 compliant.

Frequently Asked Questions (FAQ)

Q: Can CM6350R-683 be used as a direct replacement for CM6350-683? A: Yes. CM6350R-683 is electrically and mechanically identical. The primary differences are packaging format (Tape & Reel vs. Bulk) and RoHS3 compliance status. Both parts share the same 68 µH inductance, 4.2A current rating, and 10mOhm DC resistance.

Q: Is CM6350R-473 compatible with CM6350-683 applications? A: Compatibility depends on circuit requirements. CM6350R-473 has lower inductance (47 µH vs. 68 µH) and higher current capacity (5A vs. 4.2A). Use this substitute only if the application can tolerate reduced inductance filtering characteristics.

Q: What is the difference between bulk and tape & reel packaging? A: Bulk packaging is suitable for manual assembly or small-volume applications. Tape & Reel (TR) packaging is designed for automated pick-and-place assembly equipment. Both formats contain the same component.

Q: Does RoHS compliance affect electrical performance? A: No. RoHS3 compliance relates to material composition and environmental standards, not electrical specifications. ROHS3 compliant parts (CM6350R-683 and CM6350R-473) perform identically to non-compliant versions in electrical function.

Q: Are all substitute parts from the same manufacturer? A: Yes. All parts listed (CM6350-683, CM6350R-683, CM6350R-473) are manufactured by API Delevan Inc. and belong to the CM6350 series family.
