How to confirm a drop-in replacement
Check the footprint, magnetics schematic, speed grade, PoE tier, LEDs, latch and shielding against the TeleWire Technology mechanical drawing, then validate a sample on your board. The 8-point drop-in checklist on the RJ45 modular jack hub explains each check.
Manufacturer names and part numbers are used to identify the parts TeleWire Technology products replace. TeleWire Technology is not affiliated with or endorsed by these manufacturers. Confirm footprint, magnetics and LED configuration against the mechanical drawing before release to production.
Can't find your part, or need it validated?
TeleWire Technology's engineering team replies within 24 hours with the drop-in equivalent, its mechanical drawing and sample availability.
Confirm the footprint before layout
Request the mechanical drawing and a sample of any TeleWire Technology equivalent, then check footprint, magnetics, LEDs and shielding on your own board.
Request a sample & drawingSecond source, end-of-life or allocation
Send one part number or a whole BOM. We return a cross-reference with a Taiwan-made drop-in replacement for each line.
Share your part number or drawingTechnical FAQs
Common questions from procurement and engineering teams.
What is an RJ45 jack cross-reference?
An RJ45 jack cross-reference maps a manufacturer's part number to an equivalent jack from another supplier with the same footprint, pinout, magnetics, speed, PoE class, LEDs and shielding. The TeleWire Technology RJ45 cross-reference covers 3,703 RJ45 jack and MagJack part numbers from 32 manufacturers, each matched to a Taiwan-made drop-in replacement.
How do I find a drop-in replacement for a Bel Fuse, Halo or Pulse RJ45 jack?
Type the part number into the search box above, for example SI-60078-F, HFJ11-2450E or J00-0061NL. Punctuation does not matter. The table shows the TeleWire Technology equivalent with its ports, speed, PoE, mounting and shielding. Filter by manufacturer to browse every Bel Fuse, Halo, Pulse, TE Connectivity or Würth Elektronik part.
Which manufacturers' RJ45 part numbers can I cross-reference?
The cross-reference covers 32 manufacturers, including Bel Fuse, Halo Electronics, Pulse Electronics, TE Connectivity, Würth Elektronik, UDE, Hanrun, YDS, XMultiple, Bothhand, XFMRS, Amphenol, Molex and Stewart Connector. LINK-PP LPJ part numbers are searchable too. 1,241 of the 3,703 part numbers link directly to a TeleWire Technology jack in the online catalogue.
What is the typical lead time for custom prototypes?
Standard lead times for custom cable assembly prototypes are typically 1-2 weeks, depending on component availability and design complexity.
Can I cross-reference MagJacks with integrated magnetics and PoE?
Yes. Most entries are MagJacks: RJ45 jacks with the Ethernet isolation transformer and common-mode chokes built in. They cover 10/100 Base-T, Gigabit, 2.5G, 5G and 10GBase-T, and PoE (IEEE 802.3af), PoE+ (802.3at) and PoE++ (802.3bt). Use the Speed and PoE filters to narrow the table to your interface.
What if my RJ45 part number is not in the cross-reference?
TeleWire Technology makes more RJ45 jacks and MagJacks than are listed online. Send the part number or the datasheet drawing with "Share your part number or drawing". The engineering team replies within 24 hours with a drop-in equivalent and its mechanical drawing, including for obsolete and end-of-life parts.
What does "drawing on request" mean?
or these part numbers, TeleWire Technology supplies a drop-in equivalent that is not yet listed in the online catalogue. Select "Request drawing" on the row. The engineering team sends the mechanical drawing and the equivalent part number so you can confirm the footprint and request samples for design validation.
Why second-source RJ45 jacks from a Taiwan manufacturer?
A second source protects a program when the original RJ45 jack is discontinued, on allocation or on long lead times. TeleWire Technology jacks are made in Taiwan, giving procurement a qualified source outside mainland China, with US sales and technical support in Diamond Bar, California.
