Modular Connectors

Compare modular connectors by mating interface and contact arrangement, including 4P4C, RJ11, RJ12 and RJ45 options. Check port layout, mounting, shielding and LED details for the selected part, then match its footprint and mating-plug clearance to your assembly.

Features

The range includes single-port and multi-port layouts, straight and right-angle orientations, and a 45° option. Compare shielded and unshielded configurations, with or without LEDs. Through-hole, DIP and SMT mounting details vary by part; use the selected connector drawing to compare its footprint and position on the board.

Selection Guidance

First match the plug interface and contact arrangement. Next compare the port count and row layout with the enclosure opening, then check the PCB footprint and mating-plug clearance. Confirm shielding and LED details for the selected part. State any required data rate, PoE or integrated magnetics separately so those requirements can be checked before selection.

Frequently Asked Questions

Can connectors with the same port count use the same PCB footprint?

Check the selected part drawings. Port count alone does not establish the row arrangement, spacing, mounting holes or connector position relative to the board.

What should I confirm for a connector with LEDs?

Confirm the LED colors and pin connections required by your design. A listing marked with LEDs does not by itself specify those details; request the selected part drawing if they are not shown.

What if the contact arrangement or drawing is unclear?

Identify the product and request its contact layout or mechanical drawing before finalizing the footprint. Include the mating-plug reference so the interface can be checked.

Need a configuration not shown?

Include the part number, mating connector, key dimensions and required quantity in your inquiry.
