Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0191420003 is determined by the following critical parameters:

• Stud/Tab Size: Must be 6 Stud to ensure mechanical fit with mating connectors
• Wire Gauge Range: Must accommodate 18-22 AWG minimum; wider ranges (16-22 AWG) are acceptable as they encompass the original specification
• Termination Method: Must be Crimp to maintain compatibility with existing assembly processes
• Insulation Type: Must be Insulated (PVC) for electrical safety and environmental protection
• Color: Red designation for circuit identification
• Contact Material: Copper for electrical conductivity and corrosion resistance
• Compliance: ROHS3 compliance required for regulatory alignment

The substitute part TE Connectivity AMP Connectors 2-320665-1 meets all critical substitution criteria. It maintains the 6 stud configuration, supports the required wire gauge range (16-22 AWG), uses crimp termination, features PVC insulation, and is ROHS3 compliant.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0191420003 and TE Connectivity 2-320665-1 are active products with ROHS3 compliance and MSL 1 ratings, confirming their suitability for current applications. Selection between these parts should be based on:

• Inventory Availability: TE Connectivity 2-320665-1 shows higher stock levels (37,431 pcs vs. 1,456 pcs)
• Packaging Format: Molex is supplied in Bulk; TE Connectivity is supplied in Cut Tape (CT), which may affect assembly line integration
• Wire Gauge Flexibility: TE Connectivity's 16-22 AWG range provides broader accommodation for wire sizes below 18 AWG if future design flexibility is required
• Dimensional Tolerance: Both parts maintain compatible tongue opening dimensions (0.146" vs. 0.145"), ensuring proper mating with 6 stud connectors

Both parts satisfy the electrical and mechanical requirements for direct substitution in applications requiring insulated red 6 stud spade terminals with crimp termination.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 2-320665-1 be used as a direct replacement for Molex 0191420003?

A: Yes. Both parts share identical stud size (6 Stud), termination method (Crimp), insulation type (PVC), color (Red), and contact material (Copper). The TE Connectivity part's wire gauge range (16-22 AWG) encompasses the Molex specification (18-22 AWG), and both maintain compatible tongue opening dimensions for proper connector mating.

Q: What is the significance of the wire gauge range difference?

A: The Molex part specifies 18-22 AWG, while the TE Connectivity substitute accommodates 16-22 AWG. This wider range in the substitute part does not compromise compatibility with 18-22 AWG applications; it simply provides additional flexibility for wire sizes below 18 AWG if needed in future designs.

Q: Does packaging format affect substitution eligibility?

A: Packaging format (Bulk vs. Cut Tape) does not affect electrical or mechanical compatibility. However, it may impact assembly line processes. Bulk packaging suits high-volume manual assembly, while Cut Tape is optimized for automated pick-and-place equipment. Verify your assembly process requirements before selecting based on packaging alone.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the Molex 0191420003 and TE Connectivity 2-320665-1 are ROHS3 compliant and carry MSL 1 (Unlimited) ratings, confirming compliance with current environmental and moisture sensitivity requirements.

Q: What dimensional parameters ensure proper connector mating?

A: The tongue inside opening dimension is critical for mating with 6 stud connectors. Both parts maintain compatible dimensions: Molex at 0.146" (3.71mm) and TE Connectivity at 0.145" (3.68mm). These values ensure proper electrical contact and mechanical retention with standard 6 stud connectors.
