DKLP-0329-0804 Equivalent & Substitute Parts

Part Overview

The DKLP-0329-0804 is a 3-line common mode choke (CMC) designed for through-hole mounting with an 8A current rating and 22mOhm maximum DC resistance. Manufactured by SCHURTER Inc., this component is currently in active product status with 726 units available in stock. Common mode chokes are essential filtering components in three-phase power distribution systems, providing electromagnetic interference (EMI) suppression across multiple conductor lines. Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design revisions require alternative form factors while maintaining electrical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the DKLP-0329-0804 is determined by strict equivalence across the following critical parameters:

• Number of Lines: Must equal 3 (three-phase configuration)
• Current Rating (Max): Must equal or exceed 8A
• DC Resistance (DCR) (Max): Must not exceed 22mOhm
• Voltage Rating - DC: Must equal or exceed 760V
• Voltage Rating - AC: Must equal or exceed 540V
• Operating Temperature Range: Must encompass -25°C to 100°C
• Mounting Type: Must be Through Hole
• Approval Agency: Must include UR certification

The DKLL-0346-0804 meets all electrical and mechanical substitution criteria. Dimensional differences (50.00mm vs. 48.00mm) represent a minor form factor variation that does not affect electrical performance or functional compatibility in standard PCB layouts with adequate spacing.

Parameter Comparison

Engineering Selection Recommendations

The DKLP-0329-0804 is the preferred selection for new designs due to its active product status and ongoing manufacturer support. The DKLL-0346-0804 serves as a functional equivalent for legacy system maintenance or inventory contingency scenarios. Both components carry identical electrical specifications and UR approval certification, ensuring compliance with applicable safety and performance standards. The DKLL-0346-0804's obsolete status indicates limited future availability; however, current inventory levels (835 units) support near-term procurement requirements. PCB layout modifications may be necessary to accommodate the 2mm dimensional increase (50.00mm vs. 48.00mm) when substituting the DKLL-0346-0804 in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the DKLL-0346-0804 be used as a direct replacement for the DKLP-0329-0804?

A: Yes. Both components meet identical electrical specifications: 3-line configuration, 8A current rating, 22mOhm DCR, 760V DC / 540V AC voltage ratings, and -25°C to 100°C operating temperature range. Both are UR-approved and ROHS3 compliant. The primary difference is dimensional (50.00mm vs. 48.00mm) and product status (obsolete vs. active).

Q: What are the implications of the DKLL-0346-0804's obsolete status?

A: Obsolete status indicates the manufacturer no longer actively produces this component. While 835 units are currently in stock, future procurement may become unavailable. For new designs, the active DKLP-0329-0804 is recommended to ensure long-term supply chain continuity.

Q: Will the 2mm size difference affect PCB compatibility?

A: The DKLL-0346-0804 requires 2mm additional space in both length and width (50.00mm vs. 48.00mm). PCB layouts with adequate clearance margins will accommodate this substitution without modification. Designs with tight spacing constraints may require layout revision.

Q: Are both components certified for the same applications?

A: Yes. Both components carry UR approval and are ROHS3 compliant, meeting identical regulatory and compliance requirements for three-phase EMI filtering applications.
