Substitute Part Grouping Explanation

Substitution of the Molex 0191930549 is determined by the following critical parameters:

Primary Substitution Criteria:

• Manufacturer: Molex (same manufacturer ensures design compatibility)
• Series: VersaKrimp (maintains design family consistency)
• Terminal Type: Circular (functional form factor requirement)
• Termination Method: Crimp (assembly process compatibility)
• Insulation Type: Non-Insulated (electrical and mechanical interface requirement)
• Base Product Number: 019193 (common platform designation)

The substitute part Molex 0191930296 satisfies all primary criteria while offering an active product status, ensuring continued availability and support. This part operates within the same VersaKrimp platform and maintains electrical and mechanical compatibility through shared design parameters.

Engineering Selection Recommendations

The Molex 0191930296 is the designated substitute for the obsolete Molex 0191930549. Selection of this substitute is supported by the following factors:

Product Status: The 0191930296 maintains active product status with Molex, ensuring ongoing manufacturing support, quality assurance, and supply availability. The 0191930549 is classified as obsolete and subject to discontinuation.

Regulatory Compliance: Both parts share identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications, confirming equivalent export control and tariff treatment. The substitute part carries RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements.

Design Platform: Both components operate within the VersaKrimp series architecture, maintaining design consistency and assembly process compatibility. Shared base product number (019193) confirms platform alignment.

Electrical and Mechanical Compatibility: Circular terminal type, crimp termination method, and non-insulated construction are preserved across both parts, ensuring functional equivalence in ring terminal applications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0191930296 directly replace the 0191930549 in existing assemblies?

A: The 0191930296 functions as a substitute within the VersaKrimp series. Both parts share identical terminal type (circular), termination method (crimp), and insulation characteristics (non-insulated). However, the stud size differs (1/2 stud versus 12 stud), which affects mechanical fit. Application-specific validation is required to confirm stud compatibility with existing hardware.

Q: What is the significance of the different stud sizes between these parts?

A: Stud size determines the physical fit of the ring terminal onto the connection post. The 0191930549 is designed for 12 stud applications, while the 0191930296 accommodates 1/2 stud connections. Selection must align with the stud diameter of the target assembly.

Q: Are there compliance differences between the main part and substitute?

A: Both parts share identical ECCN and HTSUS classifications. The substitute carries RoHS3 compliance and REACH unaffected status, meeting current regulatory standards. No compliance barriers exist for substitution.

Q: What wire gauge does the substitute part support?

A: The Molex 0191930296 is specified for 2 AWG wire gauge. Wire gauge compatibility must be confirmed against application requirements.

Q: Why is the main part classified as obsolete?

A: Obsolescence indicates that Molex has discontinued manufacturing of the 0191930549. The substitute part (0191930296) represents the active equivalent within the VersaKrimp platform, ensuring continued access to functionally compatible ring terminal connectors.
