Description
42878-6362 is a low-profile vertical modular jack connector from Molex, designed for PCB mounting with a 1.27 mm (0.050″) pitch. It supports a 6-position, 4-contact (6P4C) configuration, commonly used in telecom and data interfaces. The connector features selective gold and tin plating for reliable signal integrity and durability, and is optimized for compact, flush-mounted designs.
Features
- 6P4C (6 positions, 4 contacts) modular jack configuration
- Low-profile vertical PCB mounting
- 1.27 mm (0.050″) contact pitch
- Selective gold plating on contacts for improved conductivity and wear resistance
- Tin-plated terminals for reliable soldering
- Flush mount, flangeless design for compact integration
- Supports standard modular plug interfaces (RJ-type)
- Designed for 2 PCB thickness mounting compatibility

Design Notes
- Ensure PCB footprint matches Molex SDA-42878 series drawings for proper alignment
- Selective gold plating thickness should be considered for mating cycle requirements
- Maintain controlled impedance if used for data/communication lines
- Mechanical reinforcement may be required in high insertion-cycle applications
- Verify panel clearance for flush-mount installation
How to Choose This Part
