DC630-334K Equivalent & Substitute Parts Reference

Part Overview

The DC630-334K is a 330 µH unshielded wirewound inductor manufactured by API Delevan Inc., rated for 1.72 A continuous current with a maximum DC resistance of 315 mOhm. This through-hole radial component operates across the temperature range of -55°C to 125°C and is specified for inductance measurement at 10 kHz. The part is currently active in production with 624 units in stock. Substitute parts are identified when electrical parameters, mechanical dimensions, and mounting characteristics remain within specification tolerances, enabling direct replacement in circuit applications.

Substitute Part Grouping Explanation

Substitution eligibility for the DC630-334K is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Inductance value: 330 µH at ±10% tolerance
• Current rating: 1.72 A minimum
• Saturation current: 3.8 A minimum
• DC resistance: 315 mOhm maximum
• Shielding configuration: Unshielded

Mechanical Equivalence Criteria:

• Mounting type: Through hole
• Package configuration: Radial, vertical cylinder
• Physical dimensions: 0.630" diameter (16.00 mm), 0.830" maximum seated height (21.08 mm)

Environmental Equivalence Criteria:

• Operating temperature range: -55°C to 125°C minimum

The DC630R-334K qualifies as a direct substitute because it maintains identical electrical specifications, mechanical form factor, and environmental ratings while utilizing a ferrite drum core construction instead of the standard wirewound core design.

Engineering Selection Recommendations

DC630-334K Selection:

• Use when RoHS non-compliant components are acceptable for the application
• Select when inventory availability of 624 units meets project lead time requirements
• Appropriate for legacy system maintenance and retrofit applications where original specifications must be preserved

DC630R-334K Selection:

• Use when ROHS3 compliance is required by design standards or regulatory requirements
• Select when higher inventory availability (1465 units) supports accelerated procurement timelines
• Appropriate for new designs and applications requiring modern environmental compliance certifications
• Ferrite drum core construction provides equivalent electrical performance with improved compliance posture

Both parts maintain identical electrical performance, mechanical compatibility, and environmental operating specifications. Selection between them is determined by compliance requirements and inventory availability rather than functional performance differences.

Frequently Asked Questions (FAQ)

Q: Can DC630R-334K replace DC630-334K in existing circuit designs?

A: Yes. The DC630R-334K provides identical electrical specifications (330 µH inductance, 1.72 A rating, 315 mOhm DCR) and mechanical form factor (through-hole radial, 0.630" diameter, 0.830" height). Direct substitution is electrically and mechanically compatible.

Q: What is the difference between the wirewound and drum core constructions?

A: The DC630-334K uses standard wirewound construction, while the DC630R-334K uses ferrite drum core construction. Both deliver identical inductance, current rating, and DC resistance specifications. The core material difference does not affect electrical performance within the specified parameters.

Q: Does the RoHS compliance difference affect circuit performance?

A: No. RoHS compliance status reflects manufacturing process and material sourcing standards, not electrical or mechanical performance. Both parts operate identically within the specified -55°C to 125°C temperature range and deliver the same 330 µH inductance at 10 kHz.

Q: Are the physical dimensions identical between both parts?

A: Yes. Both parts share identical mechanical specifications: 0.630" diameter (16.00 mm), 0.830" maximum seated height (21.08 mm), radial vertical cylinder package, and through-hole mounting configuration. PCB layout and mechanical clearance requirements are identical.

Q: Which part should be selected for new product designs?

A: The DC630R-334K is recommended for new designs due to ROHS3 compliance certification, which aligns with current environmental and regulatory standards. The higher inventory level (1465 units) also supports production scaling.

Q: Can these parts be used interchangeably in the same PCB assembly?

A: Yes. Identical through-hole lead configuration, radial package geometry, and electrical specifications enable direct PCB footprint compatibility. No design modifications are required for substitution.
