E55150700 5521 6P Unflanged Socket with 1.2PCB
Model:E55150700
The 5521 is a 6-pin unflanged RJ45 socket designed for 1.2mm PCB mounting, with a clean, flush-mount profile that suits low-profile enclosure designs. Rated at 1.5A and 150V AC, it maintains an insulation resistance of 1000 MΩ minimum for dependable signal integrity. Commonly found in compact networking devices, set-top boxes, and consumer electronics with tight chassis tolerances.
Key Features
- Unflanged flush-mount profile minimizes panel protrusion for clean enclosure aesthetics
- 6-pin configuration supports RJ11/RJ12 telephony and low-speed data interfaces
- 1.2mm PCB compatibility enables use in slim, lightweight product designs
- 1.5A / 150V AC rating covers standard telephony and low-power data circuits
- No flange design reduces mechanical stress on PCB during mating cycles
Key Specifications

Frequently Asked Questions
What is the advantage of an unflanged design over a flanged RJ45 socket?
An unflanged socket sits flush with or slightly recessed into the PCB, reducing overall connector height and eliminating the mechanical flange that typically anchors the part to a panel. This suits internal board-mount applications where panel alignment is handled by the enclosure design.
Does the 5521 require a specific PCB footprint for 1.2mm boards?
Yes. The pin length and body geometry are optimized for 1.2mm PCB thickness. Using a standard 1.6mm PCB footprint may result in insufficient solder joint depth. CZT provides recommended footprint drawings — request the datasheet for exact dimensions.
Can the 5521 be used in high-vibration industrial environments?
The unflanged design relies primarily on solder joints for mechanical retention. In high-vibration environments, additional adhesive or mechanical support may be needed. For demanding industrial applications, consider CZT's flanged or panel-mount variants with enhanced retention.
