Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DMNF1-63FIB-3K is determined by strict equivalence across the following critical parameters:

• Tab Width: 0.250" (6.35mm) — ensures mechanical fit with mating connectors
• Tab Thickness: 0.032" (0.81mm) — maintains contact pressure and electrical performance
• Wire Gauge Compatibility: 18-22 AWG — preserves termination integrity
• Insulation Classification: Fully Insulated — maintains electrical safety and isolation
• Termination Method: Crimp — ensures compatibility with existing assembly processes
• Terminal Type: Standard — confirms functional equivalence
• Gender: Female — maintains connector polarity

The substitute part DNF18-250FIB-3K meets all these criteria, establishing direct functional equivalence despite minor variations in overall length and contact material specifications.

Parameter Comparison

Engineering Selection Recommendations

The DNF18-250FIB-3K is the direct substitute for the obsolete DMNF1-63FIB-3K. Both components are manufactured by Panduit Corp and share identical electrical and mechanical specifications across all critical parameters.

The substitute part offers the advantage of Active product status, ensuring continued availability and supply chain reliability. The DNF18-250FIB-3K carries ROHS3 compliance and REACH Unaffected certification, meeting current environmental and regulatory requirements.

The minor difference in overall length (0.038" / 0.96mm shorter) does not affect functional compatibility, as this variation falls within typical mechanical tolerances for quick connect terminal applications and does not impact mating connector engagement or electrical performance.

Frequently Asked Questions (FAQ)

Q: Can DNF18-250FIB-3K be used as a direct replacement for DMNF1-63FIB-3K?
