Key Parameters

Substitute Part Grouping Explanation

Substitution of the CM6350-333 is based on strict equivalence of the following critical parameters:

• Inductance Value: 33 µH @ 10 kHz
• Current Rating: 5.5A maximum
• DC Resistance: 7mOhm maximum
• Number of Lines: 2-line configuration
• Mounting Type: Surface Mount
• Package Footprint: Horizontal, 4 PC Pad with dimensions 0.360" L x 0.360" W (9.14mm x 9.14mm)
• Height: 0.210" (5.33mm) maximum
• Operating Temperature Range: -55°C to 105°C
• Filter Type: Power Line

The CM6350R-333 qualifies as a direct substitute because it maintains identical electrical specifications and mechanical dimensions while offering improved compliance status.

Parameter Comparison

Engineering Selection Recommendations

The CM6350R-333 is a direct functional and mechanical equivalent to the CM6350-333. Both parts are manufactured by API Delevan Inc. and maintain active product status. The primary distinction is regulatory compliance: the CM6350R-333 achieves ROHS3 compliance, whereas the CM6350-333 is RoHS non-compliant. For applications subject to RoHS3 requirements or environmental regulations, the CM6350R-333 is the appropriate selection. Both parts share identical electrical performance characteristics, mechanical footprints, and thermal operating ranges, ensuring interchangeability at the circuit level. Selection between these parts should be determined by applicable compliance mandates and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can the CM6350R-333 be used as a direct replacement for the CM6350-333 in existing designs?

A: Yes. The CM6350R-333 maintains identical inductance (33 µH @ 10 kHz), current rating (5.5A), DC resistance (7mOhm), mechanical dimensions (0.360" x 0.360" x 0.210"), and operating temperature range (-55°C to 105°C). No circuit modifications are required.
