• Current Rating (Max): 8A (load capacity specification)
• DC Resistance (DCR) (Max): 22mOhm (electrical performance specification)
• Voltage Rating - DC: 760V (insulation and safety requirement)
• Voltage Rating - AC: 540V (insulation and safety requirement)
• Operating Temperature Range: -25°C to 100°C (environmental compatibility)
• Mounting Type: Through Hole (PCB assembly compatibility)
• RoHS Status: ROHS3 Compliant (regulatory compliance)
• Approval Agency: UR (safety certification)

The DKLL-0346-0804 has one identified parametric equivalent that meets all critical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The DKLP-0329-0804 is the identified parametric equivalent for the obsolete DKLL-0346-0804. Both components are manufactured by SCHURTER Inc. and share identical electrical specifications across all critical parameters: 3-line configuration, 8A current rating, 22mOhm DCR, 760V DC / 540V AC voltage ratings, and -25°C to 100°C operating temperature range.

The DKLP-0329-0804 holds active product status, ensuring ongoing availability and supply chain continuity. Both parts maintain ROHS3 compliance and UR approval certification, satisfying regulatory and safety requirements.

The dimensional difference (50.00mm vs. 48.00mm) represents a minor footprint reduction in the substitute part. PCB layout verification is necessary to confirm that the smaller footprint accommodates existing through-hole mounting patterns and clearance requirements in the target application.

Frequently Asked Questions (FAQ)

Q: Can the DKLP-0329-0804 directly replace the DKLL-0346-0804 in existing designs?

A: The DKLP-0329-0804 matches all electrical specifications of the DKLL-0346-0804. However, the substitute part has a smaller physical footprint (48.00mm vs. 50.00mm). PCB layout compatibility must be verified before implementation to ensure the reduced dimensions do not conflict with existing mounting hole patterns or component spacing.

Q: What makes the DKLP-0329-0804 a suitable substitute?

A: The substitute part meets all critical electrical parameters: identical 3-line configuration, 8A current rating, 22mOhm DCR, voltage ratings (760V DC / 540V AC), and operating temperature range (-25°C to 100°C). Both components share the same manufacturer, mounting type (through-hole), and regulatory certifications (ROHS3, UR approval).

Q: Why is the DKLL-0346-0804 obsolete?

A: The DKLL-0346-0804 is classified as obsolete. The DKLP-0329-0804 is the active equivalent from SCHURTER Inc., ensuring continued product support and supply availability.

Q: Are there any compliance differences between the two parts?

A: No. Both the DKLL-0346-0804 and DKLP-0329-0804 are ROHS3 compliant, REACH unaffected, and hold UR approval certification. Compliance status is identical.

Q: What is the primary consideration when switching from DKLL-0346-0804 to DKLP-0329-0804?

A: The primary consideration is the dimensional footprint reduction from 50.00mm to 48.00mm. Verify that PCB through-hole spacing and component clearances accommodate the smaller package dimensions.
