Molex 0190170044 Quick Connect Female Crimp Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0190170044 is a 0.205" (5.21mm) quick connect female crimp connector designed for 14-16 AWG wire termination with non-mating end insulation. This terminal is part of the InsulKrimp series and is classified as a standard quick connect receptacle for free-hanging in-line applications. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling direct replacement in applications where the core functional requirements remain unchanged.

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0190170044 is determined by strict alignment of the following critical parameters:

• Tab width: 0.205" (5.21mm) — ensures mechanical fit in mating connectors
• Tab thickness: 0.032" (0.81mm) — maintains contact pressure and electrical performance
• Tab length: 0.250" (6.35mm) — defines insertion depth and retention
• Wire gauge range: 14-16 AWG — establishes current-carrying capacity and crimp barrel sizing
• Gender: Female receptacle — defines mating interface
• Termination: Crimp — specifies wire attachment method
• Insulation: Non-mating end insulated — provides electrical safety at the wire termination point
• Contact material: Brass — ensures corrosion resistance and conductivity
• RoHS3 compliance — meets environmental regulatory requirements
• MSL 1 rating — confirms unlimited moisture tolerance

The TE Connectivity AMP Connectors part 640915-1 meets all substitution criteria within these parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0190170044 and TE Connectivity 640915-1 are active production parts with ROHS3 compliance and MSL 1 ratings. The critical mechanical parameters—tab width, thickness, length, and wire gauge—are identical, ensuring functional equivalence in quick connect receptacle applications. The overall length variance of 0.011" (0.28mm) falls within standard manufacturing tolerances and does not affect mating performance. The insulation diameter difference reflects design variation between manufacturers but does not compromise the non-mating end insulation function. Both parts are suitable for direct substitution in 14-16 AWG quick connect applications requiring female crimp terminals with non-mating end insulation.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the Molex 0190170044?

A: Substitution requires identical tab width (0.205"), tab thickness (0.032"), tab length (0.250"), wire gauge range (14-16 AWG), gender (female), termination method (crimp), insulation type (non-mating end insulated), and contact material (brass). All these parameters must match exactly.

Q: Is the TE Connectivity 640915-1 a direct replacement?

A: Yes. The 640915-1 meets all critical substitution parameters. The minor differences in overall length (0.011" variance) and insulation diameter are within acceptable engineering tolerances and do not affect functional performance in quick connect applications.

Q: Does the contact finish difference (Electro-Tin vs. Tin) affect compatibility?

A: No. Both finishes provide equivalent corrosion resistance and electrical conductivity for this application. Tin and electro-tin are functionally equivalent surface treatments for brass quick connect terminals.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the Molex 0190170044 and TE Connectivity 640915-1 carry ROHS3 compliance certification, meeting current environmental regulatory requirements.

Q: What is the significance of MSL 1 rating?

A: MSL 1 indicates unlimited moisture sensitivity, meaning the part requires no special moisture control during storage, handling, or assembly. Both parts carry this rating.

Q: Can I use these parts interchangeably in existing assemblies?

A: Yes, provided the mating connector accepts 0.205" tab width quick connect receptacles. The mechanical and electrical specifications are equivalent, enabling direct substitution.
