LPJK0071CNL Gigabit Tab-Up RJ45 Connector ( 1×1, Tab Up, Non-PoE, THT, EMI Tabs)

The LINK-PP LPJK0071CNL is a high-performance single-port (1×1) Gigabit Integrated Connector Module (ICM) designed for pure data 1000BASE-T networks. Engineered with a Tab-Up (Latch Up) orientation, LED-less front bezel, and a rugged nickel-plated copper alloy shield with EMI spring fingers, it provides ultra-low -1.0 dB max insertion loss and 1500 Vrms dielectric isolation.

It serves as a direct, footprint-compatible 1:1 drop-in replacement for Würth Elektronik 7499111000A, Bel Fuse 0826-1G1T-00-F, and Pulse J0G-0009NL.

Engineering Layout Benefits of LPJK0071CNL:

1. Cleaner Edge Routing: By eliminating the 4 LED signal pins found in standard MagJacks, the LPJK0071CNL frees up valuable routing channels on top and bottom PCB layers.
2. Superior RF Passband: Achieves -1.0 dB max insertion loss (outperforming standard -1.2 dB specifications), minimizing insertion attenuation over long Cat5e/Cat6 cable runs.
3. Universal PHY Compatibility: Center taps on channels 1–4 are individually isolated, allowing compatibility with both voltage-mode and current-mode PHY transceivers.

LPJK0071CNL can be evaluated for:

• Gigabit Ethernet switches
• routers
• gateways
• embedded motherboards
• network firewalls
• smart meters
• Ethernet control equipment
• communication terminals
• industrial controllers operating within the specified temperature range
• systems using separate status LEDs

FAQs About LPJK0071CNL Gigabit RJ45 MagJack

Q1: Can LINK-PP LPJK0071CNL directly replace Würth 7499111000A?

Yes. LPJK0071CNL is a 100% drop-in, pin-to-pin, footprint-compatible alternative to Würth Elektronik 7499111000A. Both parts share identical 1000BASE-T electrical topologies, 12-pin signal hole patterns without LED holes, Tab-Up latch orientations, and EMI shield spring finger designs.

Q2: What is the main application for the "Without LED" LPJK0071CNL?

LPJK0071CNL is engineered for equipment utilizing external light pipes (fiber optics) routed to front bezel panels, systems with multi-port status indicator panels, or designs that require maximum PCB edge routing density by eliminating LED drive traces.

Q3: Does LPJK0071CNL support PoE?

No. It is a Non-PoE connector designed purely for high-speed Gigabit data communication. If Power over Ethernet is required, please select LINK-PP PoE models such as LPJK1014A8NL (PoE 15.4W) or LPJK6003AONL (PoE+ 30W).
