Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DC630R-564K is determined by the following criteria:

Primary Matching Parameters:

• Inductance value: 560 µH
• Inductance tolerance: ±10%
• Core material: Ferrite
• Core type: Drum core, wirewound
• Shielding configuration: Unshielded
• Mounting type: Through hole
• Package style: Radial, vertical cylinder

Secondary Compatibility Factors:

• Current rating must not exceed the application requirement
• DC resistance must be within acceptable circuit performance limits
• Operating temperature range must cover the application environment
• Regulatory compliance (ROHS3, REACH)

The substitute part 1110-561K-RC from Bourns Inc. matches the primary inductance, core material, shielding, mounting, and package parameters. However, the current rating (800 mA) is lower than the main part (1.52 A), and the DC resistance (696 mOhm) is higher. These differences require circuit-level evaluation for specific applications.

Engineering Selection Recommendations

DC630R-564K (Primary Part):

• Recommended for applications requiring 1.52 A continuous current capacity
• Supports extended operating temperature range to 125°C
• Lower DC resistance (408 mOhm) minimizes power dissipation
• ROHS3 and REACH compliant for regulated markets

1110-561K-RC (Substitute Part):

• Suitable for applications with current requirements up to 800 mA
• Operating temperature range limited to 105°C maximum
• Higher DC resistance (696 mOhm) results in increased power dissipation
• ROHS3 and REACH compliant for regulated markets
• Identical inductance and package configuration enable mechanical interchangeability in through-hole PCB designs

Selection between these parts depends on circuit current requirements and thermal operating conditions. The DC630R-564K provides superior current handling and temperature performance. The 1110-561K-RC serves as an alternative for lower-current applications where the reduced current rating and higher resistance are acceptable.

Frequently Asked Questions (FAQ)

Q: Can the 1110-561K-RC replace the DC630R-564K in all applications?

A: No. The 1110-561K-RC has a maximum current rating of 800 mA compared to the DC630R-564K's 1.52 A rating. Substitution is valid only for circuits operating at or below 800 mA. Additionally, the operating temperature range is limited to 105°C for the substitute part versus 125°C for the main part.

Q: What is the impact of the higher DC resistance in the 1110-561K-RC?

A: The 1110-561K-RC exhibits 696 mOhm maximum DC resistance versus 408 mOhm for the DC630R-564K. This 70% increase in resistance results in higher power dissipation (I²R losses) at equivalent current levels, potentially affecting circuit efficiency and thermal performance.

Q: Are both parts mechanically compatible with the same PCB footprint?

A: Both parts use radial, vertical cylinder package configurations with through-hole mounting. Physical dimensions are similar (DC630R-564K: 0.630" diameter, 0.830" height; 1110-561K-RC: 0.660" diameter, 0.840" height). Mechanical compatibility depends on specific PCB hole spacing and clearance requirements.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the DC630R-564K and 1110-561K-RC are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations.

Q: What inductance tolerance applies to both parts?

A: Both parts are specified with ±10% inductance tolerance at their respective test frequencies (DC630R-564K at 10 kHz; 1110-561K-RC at 1 kHz). This tolerance must be considered in circuit design calculations.
