DFK-25-0001 Equivalent & Substitute Parts

Part Overview

The DFK-25-0001 is a 2-line common mode choke (CMC) designed for through-hole mounting applications requiring 1A current handling capability. Manufactured by SCHURTER Inc., this component operates across a temperature range of -25°C to 100°C and maintains ROHS3 compliance. The part is currently active in production with 946 units in stock. Substitute parts may be required due to inventory constraints, application-specific size requirements, or procurement lead time considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DFK-25-0001 is determined by the following critical parameters:

• Number of Lines: Must equal 2
• Current Rating (Max): Must equal or exceed 1A
• Mounting Type: Must be Through Hole
• Operating Temperature Range: Must encompass -25°C ~ 100°C
• Manufacturer: SCHURTER Inc.
• Series: DFK
• RoHS Status: ROHS3 Compliant

The DFK-20-0002 qualifies as a parametric equivalent substitute. While it features a reduced physical footprint (20mm vs. 25mm), it maintains identical electrical specifications for current rating, line configuration, temperature range, and regulatory compliance. The lower DC resistance (500mOhm vs. 510mOhm) represents an improvement in electrical performance.

Parameter Comparison

Engineering Selection Recommendations

Both the DFK-25-0001 and DFK-20-0002 are active products manufactured by SCHURTER Inc. and maintain identical ROHS3 compliance status. Selection between these parts should be based on:

DFK-25-0001: Select when the 25mm footprint is required by PCB layout constraints or when the higher DC resistance specification is acceptable for the application.

DFK-20-0002: Select when board space is limited and the compact 20mm footprint is advantageous. The lower DC resistance (500mOhm) provides improved electrical efficiency compared to the main part.

Both parts satisfy the same regulatory and compliance requirements (ROHS3, REACH Unaffected, EAR99 classification).

Frequently Asked Questions (FAQ)

Q: Can DFK-20-0002 be used as a direct replacement for DFK-25-0001?

A: Yes, provided that the 20mm footprint is compatible with your PCB layout. All electrical parameters, current ratings, temperature ranges, and compliance certifications are equivalent or superior.

Q: What is the difference in DC resistance between these parts?

A: The DFK-25-0001 has a maximum DC resistance of 510mOhm, while the DFK-20-0002 has a maximum of 500mOhm. The lower resistance in the substitute part represents improved performance.

Q: Are both parts suitable for the same temperature operating range?

A: Yes. Both parts operate across -25°C to 100°C, making them functionally equivalent for thermal applications.

Q: Does the size difference affect electrical performance?

A: No. The size reduction from 25mm to 20mm does not compromise electrical specifications. Both parts maintain identical current ratings (1A), line configuration (2-line), and temperature performance.

Q: Are both parts RoHS compliant?

A: Yes. Both DFK-25-0001 and DFK-20-0002 are ROHS3 compliant and REACH unaffected.
