Product details
Overview
44200R from Echelon Corporation is a passive bus-topology electrical terminator module for TP/XF-78 and TP/XF-1250 twisted-pair LonWorks networks. It provides 78 Ω impedance matching, operates from –40°C to +85°C, features flying wire leads (2 orange, 1 green earth ground), and requires no power supply. It is used at both ends of bus-configured LON channels in building automation control systems.
For engineers reviewing the 44200R datasheet, 44200R pinout, 44200R application, or 44200R equivalent, this page delivers verified termination resistance value, RoHS compliance status, UL/cUL/CE certifications, physical dimensions, and precise topology compatibility-critical for LON network commissioning and BOM validation.
Technical Context
The 44200R is designed exclusively for bus topology segments using TP/XF-78 (78 Ω characteristic impedance) and TP/XF-1250 (1250 kbps) physical layers. It functions as a passive resistive load with no active circuitry, requiring zero power and offering no signal regeneration or protocol handling.
Unlike free-topology terminators (e.g., 44100R), the 44200R is specified only for end-point placement on linear bus segments and must be installed in pairs-one at each physical end-to prevent signal reflections and ensure reliable LON message transmission at up to 1250 kbps.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus-topology LON network termination applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 44200 | Identical electrical specs and mechanical form factor; non-RoHS version (pre-2006 production) | Not compliant with EU RoHS Directive 2002/95/EC; restricted for new designs in EU markets | Select 44200R for all new deployments requiring RoHS conformance and global regulatory acceptance. |
| 44101R | Designed for TP/FT-10 (78 Ω, 78 kbps); lacks XF-1250 speed support and has different thermal rating (–25°C to +70°C) | Only suitable for legacy FT-10 bus segments-not interoperable with XF-78/XF-1250 physical layer signaling | Choose 44101R only for brownfield FT-10 upgrades; 44200R is mandatory for XF-78/XF-1250 deployments. |
Compared with 44200 and 44101R, the 44200R uniquely supports both TP/XF-78 and TP/XF-1250 bus topologies with full RoHS compliance and extended temperature range, making it the sole qualified terminator for new high-speed LON building automation installations.

FAQ
What is the exact termination resistance value of the 44200R?
The 44200R provides a precision 78 Ω differential termination impedance, matched to the characteristic impedance of TP/XF-78 and TP/XF-1250 twisted-pair media. This value is fixed and non-adjustable, ensuring consistent signal reflection suppression across all compliant bus segments where the 44200R is deployed.
Can the 44200R be used on a free-topology TP/FT-10 network?
No-the 44200R is explicitly designated for bus topology TP/XF-78 and TP/XF-1250 channels only. Free-topology TP/FT-10 segments require Model 44100R terminators. Using 44200R on free-topology networks violates Echelon's specification and may cause communication failures due to incorrect impedance placement and topology mismatch.
Does the 44200R require a power supply or generate heat during operation?
No-the 44200R is a fully passive device containing only precision resistors and insulated wire leads. It draws zero current, produces no heat, and requires no voltage rails or thermal derating. Its operation is purely resistive, making it safe for installation in sealed enclosures or behind base plates without ventilation concerns.
What certifications does the 44200R hold, and where are they applicable?
The 44200R carries UL Recognized, cUL Recognized, and CE Mark certifications. These validate its safety for use in commercial building systems worldwide-including HVAC, lighting, and fire alarm subsystems-under NEC Article 725, CSA C22.2 No. 205, and EN 60950-1 requirements.
Is the 44200R compatible with shielded twisted-pair cable?
No-Echelon explicitly states that the 44200R (and all listed terminators) must not be used with shielded cables. The design assumes unshielded twisted pair (UTP). For shielded media, Echelon provides separate schematic guidance; using 44200R with shielded cable risks ground loops, noise coupling, and non-compliant emissions.
