TW27553AENL 10/100/1000 Base-T RJ45 MagJack, Tab Up, Green/ Yellow LED

The TeleWire Technology TW27553AENL is a 10/100/1000 Base-T EMI-finger shielded RJ45 MagJack with integrated magnetics. Manufactured in Taiwan.

Cross Reference

  • Pulse JXD1-9015NL — the TW27553AENL cross-references to this part.
  • Pulse JXD1-9025NL — a further published equivalent on the same footprint.
  • LINK-PP LPJG16442AENL — same footprint, sourced outside mainland China.

Selection Notes

  • 10/100/1000 Base-T — matched magnetics for this line rate, no external transformer.
  • Green/ Yellow LEDs — indicated condition set by the host PHY design.
  • −40 °C to +85 °C — the range asked for in outdoor and factory-floor housings.
  • Integrated magnetics — isolation and common-mode choke inside the connector, not on the PCB.

Typical application: industrial gigabit switching in cabinets that see the full temperature swing.

Pricing for the TW27553AENL ranges from $0.50 to $3.00 USD depending on order quantity and configuration, with volume tiers available on request.

What is a Taiwan-made alternative to the Pulse JXD1-9015NL?
The TW27553AENL from TeleWire Technology cross-references to the Pulse JXD1-9015NL and to LINK-PP LPJG16442AENL. 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.
Which manufacturers' parts does the TW27553AENL replace?
The TW27553AENL cross-references to Pulse JXD1-9015NL; Pulse JXD1-9025NL, and to LINK-PP LPJG16442AENL. TeleWire Technology publishes the full cross-reference so a sourcing engineer can qualify one Taiwan-built part against several incumbents at once.
How do I qualify the TW27553AENL as a second source?
Request a sample of the TW27553AENL and the mechanical drawing from TeleWire Technology, then check the footprint against the Pulse JXD1-9015NL 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.
