Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0190710164 is determined by strict equivalence across the following critical parameters:

• Wire Gauge: 8 AWG (fixed requirement)
• Stud/Tab Size: 5/8 Stud (fixed requirement)
• Terminal Type: Circular (fixed requirement)
• Termination Method: Crimp (fixed requirement)
• Contact Material: Copper (fixed requirement)
• Contact Finish: Tin (fixed requirement)
• Insulation: Insulated PVC (fixed requirement)
• Series: InsulKrimp (manufacturer series designation)

The substitute part Molex 0190710173 maintains all critical electrical and mechanical parameters required for functional equivalence. Dimensional variations in outer width and overall length do not affect the core electrical connection or stud interface compatibility. Both parts are manufactured by Molex within the same InsulKrimp series and share identical wire gauge, stud size, and contact specifications.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0190710173 is the manufacturer-recommended substitute for the discontinued Molex 0190710164. Both parts maintain identical electrical specifications, contact geometry, wire gauge compatibility, and stud interface dimensions. The substitute part carries Active product status, ensuring continued availability and supply chain reliability.

Compliance certifications are equivalent across both parts: ROHS3 compliance, REACH unaffected status, and MSL Level 1 rating. The dimensional increases in outer width and overall length of the substitute part do not compromise functional compatibility in standard 8 AWG ring terminal applications with 5/8 inch studs.

Selection of the 0190710173 substitute is appropriate for new procurement, system redesigns, and maintenance applications where the original 0190710164 specification is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0190710173 be used as a direct replacement for the 0190710164 in existing assemblies?

A: Yes. Both parts share identical wire gauge (8 AWG), stud size (5/8 inch), terminal type (circular), and contact specifications. The dimensional differences in outer width and length do not affect the electrical connection or stud interface compatibility.

Q: What is the significance of the Last Time Buy status on the 0190710164?

A: Last Time Buy indicates that Molex has discontinued production of this part number. The 0190710173 is the active substitute within the same InsulKrimp series and should be used for all future procurement.

Q: Are there any compliance differences between these two part numbers?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical MSL Level 1 ratings. Regulatory and environmental compliance requirements are met by both parts.

Q: Does the larger overall length of the 0190710173 affect installation?

A: The increased length and width are dimensional characteristics of the substitute design. Compatibility depends on the specific application space and stud configuration. Standard 8 AWG ring terminal applications with 5/8 inch studs accommodate both part geometries.

Q: What is the base product number relationship between these parts?

A: Both the 0190710164 and 0190710173 share the base product number 019071, confirming they are part of the same product family within the InsulKrimp series.
