Why Choose Our Modular Jack?
Taiwan-Made Precision Engineering
Unlike generic commodity connectors, our jacks are engineered in Taiwan with high-precision stamping and molding to ensure consistent mechanical stability.
Comprehensive Range (ISO 9001 Certified)
From standard Cat5e discrete jacks to complex 10G PoE++ integrated modules, we manufacture the entire spectrum of RJ45 solutions in our Taiwan facilities.
Direct Cross-Reference Capabilities
We provide pin-to-pin compatible replacements for TE Connectivity, Amphenol, Pulse, Belfuse, and Molex, helping you secure your supply chain and reduce BOM costs.
Customization Expert
We support custom modifications including LED color changes, selective gold plating (up to 50u"), special EMI finger configurations, and custom pinouts.
Technical FAQs
Common questions from procurement and engineering teams.
What types of Modular Jack Connectors do you manufacture?
We manufacture a complete range of PCB-mount modular jacks, including Integrated (MagJack), Discrete (Non-Integrated), Vertical (Top Entry), Multi-port (Ganged/Stacked), Low-Profile (Sunk), and RJ45+USB Combo jacks. We support speeds from 10/100 Base-T to 10G Base-T.
Can you cross-reference major brands like TE, Amphenol, or Pulse?
Yes. A core part of our service is providing high-quality, Taiwan-made alternatives to major brands. We can cross-reference part numbers from TE Connectivity, Amphenol, Molex, Pulse Electronics, Belfuse, and Wurth, often offering shorter lead times and better cost structures.
Do you offer custom RJ45 configurations for specific LED or shielding requirements?
Absolutely. We offer customization for LED colors, housing dimensions, gold plating thickness (up to 50u"), shield EMI finger configurations, and specific internal magnetic schematics to match your PHY chip requirements.
Do you offer samples for testing and validation?
Yes, we support OEM/ODM projects with samples for engineering validation. For standard "catalogue" parts, samples can often be shipped within 48 hours. For custom specifications (e.g., specific LED colors or magnetics), we can produce prototypes quickly due to our in-house engineering in Taiwan.
What is the standard lead time for modular jacks?
For standard stock items, we can ship immediately. For volume production orders, our typical lead time is 4-6 weeks, which is significantly faster than the current industry average for major brands. Expedited services are available for urgent NPI builds.
