Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0191930321 is determined by strict equivalence across the following critical parameters:

• Wire Gauge: 2 AWG (electrical current capacity requirement)
• Stud/Tab Size: 3/8 Stud (mechanical mounting interface)
• Terminal Type: Circular (form factor and connection geometry)
• Termination Method: Crimp (assembly process compatibility)
• Insulation Type: Non-Insulated (electrical and thermal characteristics)
• Contact Material: Copper (electrical conductivity and corrosion resistance)
• Contact Finish: Tin (surface protection and solderability)
• Features: Brazed Seam (structural integrity and reliability)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

The substitute part Molex 0191930298 maintains equivalence across all critical electrical and mechanical parameters. Dimensional variations in width and length do not affect functional compatibility when the stud size, wire gauge, and termination method remain constant.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0191930298 is the direct functional equivalent for the discontinued Molex 0191930321. Both parts maintain identical electrical and mechanical specifications across wire gauge, stud size, termination method, contact material, and finish. The substitute part carries Active product status, ensuring continued availability and supply chain reliability.

Both parts satisfy ROHS3 compliance requirements and carry MSL Rating 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling. The dimensional differences between the main part and substitute (width and length) do not affect functional performance in applications where the 3/8 stud interface and 2 AWG wire capacity are the determining factors.

Selection of the Molex 0191930298 is appropriate for direct replacement in applications currently specified for the 0191930321, with no additional qualification or testing required beyond standard assembly procedures.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0191930298 directly replace the Molex 0191930321 in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: 2 AWG wire gauge, 3/8 stud connection, circular terminal type, crimp termination, copper contact with tin finish, and brazed seam construction. The dimensional differences do not affect functional compatibility.

Q: What is the significance of the Last Time Buy status for the 0191930321?

A: Last Time Buy indicates that the manufacturer has discontinued production of this part number. The Molex 0191930298 is the recommended active alternative for continued procurement and future applications.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 compliant and carry identical MSL Rating 1 (Unlimited). No additional certifications or qualifications are required when transitioning from the main part to the substitute.

Q: Do the dimensional differences (width and length) affect stud compatibility?

A: No. The 3/8 stud size is identical on both parts. Dimensional variations in the ring body do not impact the mechanical interface or electrical performance at the stud connection point.

Q: What packaging format is available for the Molex 0191930298?

A: The substitute part is supplied in Bulk packaging, consistent with the original part specification.
