Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DC630-473K is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Inductance value: 47 µH at ±10% tolerance
• Current rating: 3.98 A minimum continuous current capacity
• Saturation current: 10 A minimum
• DC resistance: 62 mOhm maximum
• Inductance test frequency: 10 kHz

Mechanical Equivalence Criteria:

• Mounting type: Through hole only
• Package configuration: Radial, vertical cylinder orientation
• Physical dimensions: 0.630" diameter (16.00 mm) and 0.830" maximum seated height (21.08 mm)
• Operating temperature range: -55°C to 125°C minimum

Functional Equivalence Criteria:

• Unshielded configuration
• Wirewound construction type

The DC630R-473K qualifies as a direct substitute because it maintains all electrical parameters, mechanical dimensions, mounting configuration, and operating temperature specifications identical to the DC630-473K while utilizing a ferrite drum core construction instead of standard wirewound core material.

Parameter Comparison

Engineering Selection Recommendations

DC630-473K Selection: Select the DC630-473K when the application circuit design specifically requires the original wirewound core construction without ferrite material. This part maintains active production status and has adequate inventory availability. However, this part carries RoHS non-compliant status, which may restrict use in applications subject to RoHS3 regulatory requirements.

DC630R-473K Selection: The DC630R-473K substitute provides identical electrical performance and mechanical compatibility while offering ROHS3 compliance certification. This part is suitable for applications requiring regulatory compliance with RoHS3 standards. Both parts maintain equivalent current ratings, inductance values, DC resistance specifications, and physical dimensions. The ferrite drum core construction in the DC630R-473K does not alter the electrical performance parameters specified at 10 kHz test frequency. Inventory availability is equivalent between both parts.

Compliance Consideration: Applications subject to RoHS3 regulatory frameworks should utilize the DC630R-473K substitute due to its ROHS3 compliant status. The DC630-473K remains suitable for applications without RoHS3 compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the DC630R-473K directly replace the DC630-473K in existing circuit designs?

A: Yes. The DC630R-473K maintains identical inductance (47 µH ±10%), current rating (3.98 A), saturation current (10 A), DC resistance (62 mOhm max), and physical dimensions (0.630" diameter, 0.830" height). Through-hole mounting configuration and operating temperature range (-55°C to 125°C) are identical. No circuit design modification is required.

Q: What is the difference between the DC630-473K and DC630R-473K?

A: The primary difference is core material construction. The DC630-473K uses standard wirewound construction with unspecified core material. The DC630R-473K uses ferrite drum core construction. Both maintain identical electrical specifications at the 10 kHz test frequency. The DC630R-473K additionally carries ROHS3 compliance certification, while the DC630-473K is RoHS non-compliant.

Q: Are the physical dimensions identical between both parts?

A: Yes. Both parts share identical dimensions: 0.630" diameter (16.00 mm) and 0.830" maximum seated height (21.08 mm). Both use radial, vertical cylinder package configuration. PCB footprint and mounting hole spacing are identical.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring ROHS3 compliance, select DC630R-473K. For applications without RoHS3 compliance requirements, either part is suitable based on inventory and supply chain considerations.

Q: Do both parts operate across the same temperature range?

A: Yes. Both the DC630-473K and DC630R-473K operate across the identical temperature range of -55°C to 125°C.

Q: Is the inductance tolerance identical?

A: Yes. Both parts maintain ±10% inductance tolerance at the 10 kHz test frequency.

Q: What is the current handling capacity of both parts?

A: Both parts are rated for 3.98 A continuous current with 10 A saturation current (Isat) maximum.
