Looking at the Teltonika RUT950?
Here is the LINBLENET T300-390 side by side.

A factual comparison for system integrators: what carries over, what to check, and how to run a 1-unit evaluation before you commit to anything.

Competitor specifications as published by the vendor; confirm the exact SKU on your BOM, as regional variants differ.

What carries over from your existing design

Same wiring, same job

  • RJ45 on the LAN side, terminal block for field wiring, wide DC input
  • 4 Ethernet ports on the RUT950 → 5 on the T300-390 — one extra port for the device you were about to add a mini-switch for
  • DIN-rail / panel mounting options

Two SIM slots, same idea

  • Dual-SIM with automatic failover, like for like
  • One practical note: both SIMs should ride different carriers — failover between two SIMs on the same network gains you little

What you gain

  • A serial port the RUT950 doesn't have — RS-232/485 configurable per unit, one SKU instead of two order variants
  • Solder-down (chip) SIM support for high-vibration and unattended sites
  • MOQ 1 — run a real evaluation without a project-size commitment

What to check honestly

  • Cloud platform: Teltonika RMS is mature. If remote fleet management is central to your offer, evaluate both platforms
  • GNSS: not a standard feature on the T300-390 — confirm for your configuration before specifying
  • Enclosure size: check your cabinet cut-out against the datasheet before calling anything a drop-in
The second-source way to try it: keep the RUT950 where it works. Take one T300-390 unit, run your own protocol test on your own bench, and keep it as a fallback for the weeks your main supplier's lead time slips. MOQ is 1 unit and stock ships in 5–7 working days — the industry norm is 4–8 weeks. Nothing to lose, something to fall back on.

Certificate numbers are verifiable with the issuing bodies. Need a certificate in your own company name? That is an OEM / private-label conversation — we do that from 1 unit.

Run your own test — 1 unit is enough

Tell us the model on your BOM and the market you deploy in. We will confirm the matching configuration, band plan and lead time in writing.
