TW26S78648A58NL 10/100/1000 Base-T 2x6 Port RJ45 MagJack, Tab Both, Yellow&Green/ Yellow&Green LED

The TeleWire Technology TW26S78648A58NL is a 10/100/1000 Base-T 2x6 EMI-finger shielded RJ45 MagJack with integrated magnetics. Manufactured in Taiwan.

Cross Reference

  • TE Connectivity 1840921-1 — the TW26S78648A58NL cross-references to this part.
  • UDE RM7-ZZ-0002 — a further published equivalent on the same footprint.
  • LINK-PP LPJG67537A47NL — same footprint, sourced outside mainland China.

Selection Notes

  • 2x6 port array — 12 ports on one shell, saving panel width.
  • 10/100/1000 Base-T — the rate the internal transformer is wound for.
  • Yellow&Green/ Yellow&Green LEDs — indicated condition set by the host PHY design.
  • −40 °C to +85 °C — rated for unheated cabinets across the seasonal swing.

Typical application: switch and router line cards, where port density per panel inch drives the design.

Pricing for the TW26S78648A58NL 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 TE Connectivity 1840921-1?
The TW26S78648A58NL from TeleWire Technology cross-references to the TE Connectivity 1840921-1 and to LINK-PP LPJG67537A47NL. 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 TW26S78648A58NL replace?
The TW26S78648A58NL cross-references to TE Connectivity 1840921-1; UDE RM7-ZZ-0002, and to LINK-PP LPJG67537A47NL. 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 TW26S78648A58NL as a second source?
Request a sample of the TW26S78648A58NL and the mechanical drawing from TeleWire Technology, then check the footprint against the TE Connectivity 1840921-1 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.
