Key Parameters

Substitute Part Grouping Explanation

Substitution of the DC630-183K is limited to components matching the following electrical and mechanical parameters:

• Inductance value: 18 µH (±10% tolerance)
• Current rating: 7 A minimum
• Saturation current: 16 A
• DC resistance: 20mOhm maximum
• Operating temperature range: -55°C ~ 125°C minimum
• Inductance test frequency: 10 kHz
• Mounting type: Through hole
• Package configuration: Radial, vertical cylinder
• Physical dimensions: 0.630" diameter (16.00mm), 0.830" max height (21.08mm)

The DC630R-183K satisfies all electrical and mechanical substitution criteria. Core material differences (ferrite drum core versus standard wirewound) do not alter the specified performance parameters within the allowed tolerance range.

Parameter Comparison

Engineering Selection Recommendations

Both the DC630-183K and DC630R-183K are active products with equivalent electrical and mechanical specifications. Selection between these components is determined by regulatory and compliance requirements:

The DC630-183K is suitable for applications without RoHS3 compliance mandates. The DC630R-183K is required for applications subject to ROHS3 regulations or customer specifications requiring compliant components. Both parts are REACH Unaffected and classified as EAR99 under export control regulations.

Inventory availability supports procurement of either component: the DC630-183K maintains 1014 pcs in stock, while the DC630R-183K maintains 1368 pcs.

Frequently Asked Questions (FAQ)

Q: Can DC630R-183K replace DC630-183K in any circuit? A: Yes. Both components meet identical electrical specifications: 18 µH inductance, 7 A rating, 20mOhm maximum DCR, and identical operating temperature range. The physical package, mounting type, and dimensions are identical.

Q: What is the difference between DC630-183K and DC630R-183K? A: The primary difference is RoHS compliance status. DC630-183K is RoHS non-compliant; DC630R-183K is ROHS3 compliant. The DC630R-183K uses a ferrite drum core construction versus standard wirewound construction in the DC630-183K. Core material differences do not affect the specified inductance, current rating, or DC resistance values.

Q: Are the physical dimensions identical between these parts? A: Yes. Both components are packaged as radial, vertical cylinder with 0.630" diameter (16.00mm) and 0.830" maximum seated height (21.08mm).

Q: When should DC630R-183K be selected over DC630-183K? A: Select DC630R-183K when RoHS3 compliance is required by regulation or customer specification. Select DC630-183K when RoHS compliance is not mandated and non-compliant components are acceptable.

Q: Are these parts suitable for high-frequency applications? A: Inductance values for both parts are tested at 10 kHz. Frequency-dependent behavior beyond the specified test frequency is not provided in the documented parameters.
