• Identical test frequency: 10 kHz

Matching Mechanical Specifications:

• Identical mounting type: Through Hole
• Identical package configuration: Radial, Vertical Cylinder
• Identical physical dimensions: 0.630" Dia (16.00mm), 0.830" Height (21.08mm)

Core Construction Difference: The DC630R-682M utilizes a drum core ferrite construction, while the DC630-682M uses an unshielded wirewound design. Both configurations deliver identical electrical performance across all specified parameters.

Parameter Comparison

Engineering Selection Recommendations

DC630-682M: Suitable for applications where RoHS non-compliant components are acceptable or required by legacy design specifications. Active product status ensures continued availability through standard procurement channels.

DC630R-682M: Preferred for new designs and applications requiring RoHS3 compliance. The drum core ferrite construction provides an alternative implementation path while maintaining electrical equivalence. Higher inventory levels (2,451 pieces) indicate stronger supply chain availability. Active product status confirms ongoing manufacturability.

Both components share identical electrical performance and mechanical compatibility, making selection dependent on regulatory compliance requirements and supply chain considerations rather than technical performance.

Frequently Asked Questions (FAQ)

Q: Can DC630R-682M directly replace DC630-682M in existing designs? A: Yes. Both components are electrically and mechanically equivalent across all specified parameters, including inductance, current rating, DC resistance, operating temperature range, and physical dimensions. The substitution is valid based on matching core specifications.

Q: What is the difference between the DC630-682M and DC630R-682M? A: The primary difference is core construction: the DC630-682M uses a wirewound design, while the DC630R-682M employs a drum core ferrite construction. This structural difference does not affect electrical performance, as both deliver identical inductance values, current ratings, and DC resistance specifications.

Q: Are there compliance differences between these parts? A: Yes. The DC630R-682M is ROHS3 compliant, while the DC630-682M is RoHS non-compliant. For applications requiring RoHS compliance, the DC630R-682M is the appropriate selection.

Q: Do these components have the same physical footprint? A: Yes. Both the DC630-682M and DC630R-682M share identical physical dimensions of 0.630" diameter (16.00mm) and 0.830" height (21.08mm) in radial, vertical cylinder configuration. They are mechanically interchangeable in through-hole PCB designs.

Q: Which part should I specify for new designs? A: The DC630R-682M is recommended for new designs due to ROHS3 compliance and higher inventory availability. However, either component may be specified if RoHS compliance is not a design constraint.
