TW7125AHNL 10/100 Base-T RJ45 MagJack, Tab Up, Green/ Yellow LED

The TeleWire Technology TW7125AHNL is a 10/100 Base-T EMI-finger shielded RJ45 MagJack with integrated magnetics. Manufactured in Taiwan.

Cross Reference

  • Bel Fuse SI-55004-F — the TW7125AHNL cross-references to this part.
  • Molex 0480251190 — a further published equivalent on the same footprint.
  • Molex 48025-1190 — a further published equivalent on the same footprint.

Selection Notes

  • 10/100 Base-T — the interface rate the magnetics are matched to.
  • Green/ Yellow LEDs — indicated condition set by the host PHY design.
  • −40 °C to +85 °C — rated for unheated cabinets across the seasonal swing.
  • Integrated magnetics — isolation on all four pairs, short routing to the PHY.

Typical application: industrial gateways and factory-floor equipment rated beyond the commercial range.

Pricing for the TW7125AHNL 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 Bel Fuse SI-55004-F?
The TW7125AHNL from TeleWire Technology cross-references to the Bel Fuse SI-55004-F and to LINK-PP LPJ6014AHNL. 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 TW7125AHNL replace?
The TW7125AHNL cross-references to Bel Fuse SI-55004-F; Molex 0480251190; Molex 48025-1190; Pulse JP009SX88X2XXXXX-024-G; Würth Elektronik 74990112116A, and to LINK-PP LPJ6014AHNL. 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 TW7125AHNL as a second source?
Request a sample of the TW7125AHNL and the mechanical drawing from TeleWire Technology, then check the footprint against the Bel Fuse SI-55004-F 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.
