DC630R-223K Equivalent & Substitute Parts

Part Overview

The DC630R-223K is a 22 µH unshielded drum core wirewound inductor manufactured by API Delevan Inc. This through-hole component is designed for applications requiring fixed inductance with a current rating of 6.26 A and maximum DC resistance of 25 mOhm. The part is currently active in production with 870 pieces in stock. Equivalent and substitute parts are identified when design requirements permit relaxation of specific electrical parameters while maintaining core functional characteristics such as inductance value, core type, and mounting configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DC630R-223K is permissible when the following conditions are satisfied:

Fixed Requirements (No Deviation Allowed):

• Inductance value: 22 µH
• Inductance tolerance: ±10%
• Core type: Ferrite drum core, unshielded
• Mounting type: Through hole, radial vertical cylinder configuration
• RoHS compliance: ROHS3 Compliant

Flexible Parameters (Application-Dependent):

• Current rating: Substitute must equal or exceed the application's maximum current requirement
• DC resistance: Lower values are acceptable; higher values require thermal analysis
• Operating temperature range: Substitute range must encompass application operating conditions
• Physical dimensions: Minor variations acceptable if PCB layout permits

The substitute part 1110-220K-RC (Bourns Inc.) satisfies all fixed requirements and is grouped as an equivalent when application current requirements do not exceed 5.5 A and operating temperature does not exceed 105°C.

Parameter Comparison

Engineering Selection Recommendations

DC630R-223K (API Delevan Inc.) - Primary Selection:

• Use when application current requirement is 5.5 A to 6.26 A
• Use when operating temperature may reach 125°C
• Use when PCB layout is constrained to 0.630" diameter maximum
• Product status: Active with 870 pieces in stock

1110-220K-RC (Bourns Inc.) - Substitute Selection:

• Use when application current requirement does not exceed 5.5 A
• Use when operating temperature does not exceed 105°C
• Use when slightly larger footprint (0.660" diameter, 0.840" height) is acceptable
• Use when lower DC resistance (20 mOhm vs. 25 mOhm) provides thermal benefit
• Product status: Active with 972 pieces in stock
• Regulatory compliance: ROHS3 and REACH requirements met

Both parts maintain identical inductance specifications, core construction, and mounting configuration. Selection between primary and substitute depends on application current and temperature requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1110-220K-RC substitute for the DC630R-223K in all applications?

A: No. The 1110-220K-RC has a lower current rating (5.5 A vs. 6.26 A) and narrower operating temperature range (-55°C to 105°C vs. -55°C to 125°C). Substitution is valid only when the application's maximum current does not exceed 5.5 A and operating temperature does not exceed 105°C.

Q: What is the impact of the lower DC resistance in the substitute part?

A: The 1110-220K-RC has 20 mOhm maximum DC resistance compared to 25 mOhm in the DC630R-223K. Lower DC resistance reduces resistive power dissipation (I²R losses), resulting in lower operating temperature and improved efficiency. This is a beneficial characteristic for substitution.

Q: Are there physical compatibility concerns with the substitute part?

A: The 1110-220K-RC is slightly larger: 0.660" diameter (vs. 0.630") and 0.840" height (vs. 0.830"). PCB layout must accommodate these dimensions. Both parts use identical through-hole radial vertical cylinder mounting, so footprint spacing is compatible if board space permits the larger diameter.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both DC630R-223K and 1110-220K-RC are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic components.

Q: What is the inductance test frequency difference between these parts?

A: The DC630R-223K is tested at 10 kHz, while the 1110-220K-RC is tested at 1 kHz. Both parts are specified at 22 µH with ±10% tolerance. The different test frequencies reflect manufacturer measurement standards but do not affect functional equivalence at the specified inductance value.

Q: Can the DC630R-223K be used as a substitute for the 1110-220K-RC?

A: Yes. The DC630R-223K exceeds the electrical specifications of the 1110-220K-RC (higher current rating and wider temperature range) and is therefore compatible with any application designed for the 1110-220K-RC, subject to PCB layout accommodation of the slightly smaller footprint.
