TW1131AINL 10/100 Base-T PoE RJ45 MagJack, Tab Up, Yellow&Green/Green LED

The TeleWire Technology TW1131AINL is a 10/100 Base-T RJ45 MagJack with integrated magnetics and PoE support, EMI-finger shielded, with Yellow&Green / Green status LEDs. Manufactured in Taiwan.

Cross Reference

  • Pulse JK0-0020NL — the TW1131AINL is a Taiwan-manufactured equivalent.
  • LINK-PP LPJK0020AINL — same footprint, sourced outside mainland China.

Selection Notes

  • PoE, IEEE 802.3af — up to 15.4 W at the PSE over the data pairs.
  • Integrated magnetics — isolation on all four pairs, short routing to the PHY.
  • Yellow&Green and Green LEDs — two indicators driven by the host design.
  • Tab-up latch, right-angle body — front-panel exit from an upright board.

Typical application: PoE-powered edge devices such as IP cameras, VoIP handsets and wireless access points.

Pricing for the TW1131AINL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

Validate the TW1131AINL on your board first. Samples are available for design validation, and the mechanical drawing gives the footprint before you commit a layout. Request a sample or quotation.

What is a Taiwan-made alternative to the Pulse JK0-0020NL?
The TW1131AINL from TeleWire Technology cross-references to the Pulse JK0-0020NL and to LINK-PP LPJK0020AINL. It is manufactured in Taiwan, giving buyers a supply route outside mainland China for the same footprint. Send the footprint you are designing against and TeleWire Technology will confirm compatibility.
Can the TW1131AINL be built to a different configuration?
Yes. The standard TW1131AINL ships with Yellow&Green/ Green LEDs and a tab-up latch. TeleWire Technology can change LED colour, latch direction, contact plating thickness (Gold Flash through 50 microinch) and tray or reel packaging against your drawing, while holding the footprint that matches Pulse JK0-0020NL.
How do I qualify the TW1131AINL as a second source?
Request a sample of the TW1131AINL and the mechanical drawing from TeleWire Technology, then check the footprint against the Pulse JK0-0020NL on your board. TeleWire Technology builds in Taiwan under an ISO 9001 quality system, and its engineering team will review your drawing before you commit.
