Molex 0945120111 Quick Connect Female Terminal - Equivalent & Substitute Parts
Part Overview
The Molex 0945120111 is a 0.250" (6.35mm) Quick Connect Female crimp connector terminal rated for 18-24 AWG wire gauges. This non-insulated terminal is designed for free-hanging in-line applications with steel contact material and nickel finish. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain compatibility with the 0.250" tab width, crimp termination method, and female gender configuration while accommodating the specified wire gauge range.

Substitute Part Grouping Explanation
Substitution eligibility is determined by the following critical parameters that must align with the Molex 0945120111:
- Tab Width: Must be 0.250" (6.35mm) for mechanical compatibility with mating connectors
- Tab Thickness: Must be 0.032" (0.81mm) to ensure proper contact pressure and electrical performance
- Gender: Must be Female to maintain circuit function
- Termination Method: Must be Crimp to use existing assembly equipment
- Mounting Type: Must be Free Hanging (In-Line) for application fit
- Wire Gauge Compatibility: Substitute wire gauge range must overlap with or encompass the 18-24 AWG specification
All nine substitute parts listed meet these core mechanical and electrical requirements. Wire gauge ranges vary among substitutes (12-22 AWG, 17-22 AWG, or 18-22 AWG), with all options accommodating the critical 18-22 AWG overlap band. Contact material differs (brass vs. steel) and contact finish differs (tin vs. nickel), representing material-level variations that do not affect mechanical substitution eligibility.

Engineering Selection Recommendations
All nine TE Connectivity AMP Connector substitutes are mechanically and electrically compatible with the Molex 0945120111 based on matching tab width, thickness, gender, termination method, and mounting configuration. All substitute parts carry Active product status, ensuring long-term availability and supply chain stability compared to the obsolete Molex part.
For applications requiring strict RoHS3 compliance certification, select from: TE 175020-1, TE 2238173-3, TE 280095-2, TE 41772, TE 41772-1, TE 444334-2, TE 63609-2, or TE 735212-2. TE 42743-2 carries RoHS Compliant status (not ROHS3 specific), and TE 60878-2 carries Not Applicable RoHS status.
For applications where wire gauge 24 AWG must be supported, note that all TE substitutes specify maximum 22 AWG. The Molex 0945120111 supports 18-24 AWG, while all substitutes support 18-22 AWG or broader ranges (12-22 AWG or 17-22 AWG). Wire gauge 23-24 AWG applications require evaluation of whether the 22 AWG maximum of substitutes is acceptable for the circuit design.
Contact material and finish differ across all substitutes (brass with tin finish vs. original steel with nickel finish). These material differences do not affect mechanical substitution but may influence electrical resistance characteristics and corrosion performance in specific environmental conditions.
Frequently Asked Questions (FAQ)
Q: Can TE 2238173-3 (12-22 AWG) substitute for the Molex 0945120111 (18-24 AWG)?
A: TE 2238173-3 is mechanically compatible and supports the critical 18-22 AWG overlap range. However, it does not support wire gauges 23-24 AWG. Substitution is valid only if your application does not require 23-24 AWG wire termination.
Q: Why do all TE substitutes use brass contact material instead of steel?
A: Contact material is not a substitution-limiting parameter for this terminal category. Brass with tin finish is a standard material combination in TE Faston and Fastin-Faston series terminals. Both materials provide adequate electrical conductivity and contact performance for quick-connect applications.
Q: What is the difference between TE 41772 and TE 41772-1?
A: Both parts are mechanically identical (0.250" tab width, 0.032" thickness, 18-22 AWG wire gauge, crimp termination). The primary difference is overall length: TE 41772 is 0.790" (20.06mm) while TE 41772-1 is 0.750" (19.05mm). Select based on your connector cavity depth requirements.
Q: Are all substitutes available in the same packaging as the Molex 0945120111?
A: The Molex 0945120111 packaging is not specified in the provided data. TE substitutes are available in Cut Tape (CT) packaging (most parts) or Bulk packaging (TE 60878-2). Verify packaging requirements with your procurement process.
Q: Which substitute has the highest inventory availability?
A: TE 41772-1 has the highest inventory at 54,809 pieces, followed by TE 42743-2 at 58,157 pieces. Both are suitable for high-volume applications requiring immediate availability.
Q: Do all substitutes meet REACH compliance?
A: REACH status varies. TE 2238173-3 and TE 60878-2 show REACH Unaffected status. Most other substitutes show Vendor Undefined REACH status. Verify REACH compliance requirements with your supply chain or TE Connectivity directly for applications subject to REACH regulations.
