TE Connectivity 3-640442-5 to Molex 51146-0500 5-Pin Mixed-Pitch - Custom Wire Harness
- Engineered as a highly specialized asymmetrical signal bridge, securely terminating a 5-position TE Connectivity MTA-100 series IDC receptacle (2.54mm pitch) to a 5-position Molex PanelMate series low-profile receptacle (1.25mm pitch).
- The TE MTA-100 interface (3-640442-5) utilizes rapid Insulation Displacement Contact (IDC) mass-termination technology, visually color-coded (blue housing) for precision compatibility with AWG #26 discrete wiring.
- The Molex 51146-0500 interface utilizes an ultra-low-profile crimp-and-poke architecture, accommodating precision phosphor-bronze crimp terminals to achieve secure mating in severely space-constrained flat-panel displays and consumer electronics.
- Constructed to resolve extreme density transitions, seamlessly stepping down from a standard industrial 2.54mm (0.100") board header to a miniaturized 1.25mm (0.049") logic board input using strictly controlled, highly flexible discrete wiring.
- Features robust mechanical retention mechanisms intrinsic to both architectures—including the TE friction-locking ramp and the Molex ultra-thin friction lock—actively preventing misinsertion and guaranteeing connection integrity under vibration.

We specialize in custom sourcing and manufacturing. Upload your spec sheet or drawing, and our engineering team will provide a quote within 24 hours.
What information do you need to provide a quote for a custom wire harness?
To provide an accurate quote and lead time, please provide:
- Technical Drawing or Diagram: Showing pinouts, lengths, and tolerances.
- Bill of Materials (BOM): Listing specific connectors (MPN) and wire gauges (AWG).
- Estimated Annual Usage (EAU): Helping us optimize pricing for your volume. Note: If you do not have a formal drawing, our engineering team can help create one based on your physical sample.
Can you suggest cost-saving alternatives for expensive connectors (e.g., TE, Molex, JST)?
Yes. We offer variety of alternative components.
We have extensive supply chain relationships in Taiwan and can suggest"Functionally Equivalent"alternatives that are fully compatible with major brands like TE, Molex, or JST but at a significantly lower cost. We will provide datasheets and samples of the alternative components for your approval before production.
How do you ensure quality control for custom cable assemblies?
Every single cable assembly undergoes rigorous testing before leaving our Taiwan facility. Our standard QC process includes:
- 100% Continuity Testing: Ensuring no opens, shorts, or miswires.
- Pull Force Testing: Verifying crimp strength.
- Visual Inspection: Checking for cosmetic defects and label accuracy.
- Hi-Pot Testing: Available upon request for high-voltage applications to ensure insulation integrity.
