Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for ring terminal connectors is determined by strict equivalence across the following parameters:

• Wire gauge compatibility (1/0 AWG)
• Stud size specification (1/4 inch)
• Terminal geometry (flat sided, tubular configuration)
• Termination method (crimp)
• Insulation classification (non-insulated)
• Mounting configuration (free hanging, in-line)
• Regulatory compliance (ROHS3)

The substitute part Molex 0192210422 maintains identical specifications across all critical electrical and mechanical parameters. Dimensional variations within manufacturing tolerance (thickness 0.110", width 0.728" vs. 0.725", length 1.844" vs. 1.830") do not affect functional compatibility in standard applications.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0192210422 is the direct functional equivalent for the obsolete 0192210439. Both components are ROHS3 compliant and belong to the same 19221 series. The substitute part is currently in active production status with significantly higher inventory availability (5135 pcs vs. 1062 pcs), ensuring supply chain continuity.

The 0192210422 is specified with copper contact material and tin finish, providing documented corrosion resistance and electrical conductivity characteristics suitable for high-current battery and power distribution applications. Dimensional tolerances between the two parts fall within standard manufacturing ranges for this connector category and do not introduce compatibility issues in standard mounting configurations.

Frequently Asked Questions (FAQ)

Q: Can the 0192210422 be used as a direct replacement for the 0192210439?
