Key Parameters

Substitute Part Grouping Explanation

The DKLL-0346-0330 has one parametric equivalent identified: DKLP-0329-0330. Substitution eligibility is determined by the following critical parameters that must remain constant:

• Number of Lines: 3
• Current Rating (Max): 3A
• DC Resistance (DCR) (Max): 130mOhm
• Voltage Rating - DC: 760V
• Voltage Rating - AC: 540V
• Operating Temperature Range: -25°C to 100°C
• Mounting Type: Through Hole
• Approval Agency: UR
• RoHS Status: ROHS3 Compliant

The substitute part maintains electrical equivalence across all specified parameters while differing in physical dimensions and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The DKLP-0329-0330 is the direct parametric equivalent for the obsolete DKLL-0346-0330. Both components are manufactured by SCHURTER Inc. and maintain identical electrical specifications across all critical parameters: 3-line configuration, 3A current rating, 130mOhm DCR, 760V DC / 540V AC voltage ratings, and -25°C to 100°C operating temperature range.

The primary distinction is product status: DKLP-0329-0330 is classified as active, ensuring ongoing availability and supply chain continuity. Both parts carry ROHS3 compliance and UR approval certification, meeting regulatory requirements for equivalent applications.

Physical dimensions differ slightly (50.00mm vs. 48.00mm), requiring verification of PCB layout compatibility during design transition. The substitute part is supplied in bulk packaging format.

Frequently Asked Questions (FAQ)
