XTR114U Equivalent & Substitute Parts

Part Overview

The XTR114U is a current transmitter interface integrated circuit manufactured by Texas Instruments in a 14-SOIC surface mount package. This component converts voltage input signals to voltage output signals and operates with a 20 mA supply current across the temperature range of -40°C to 85°C. The XTR114U is classified as an obsolete product, making identification of functionally equivalent alternatives essential for ongoing system support, legacy design maintenance, and component procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the XTR114U is determined by the following critical parameters:

• Functional Type: Current transmitter with voltage input and voltage output capability
• Supply Current: 20 mA operation
• Operating Temperature Range: -40°C to 85°C minimum coverage
• Package Compatibility: 14-SOIC surface mount form factor
• Electrical Interface: Voltage-to-voltage signal conversion

The XTR112U qualifies as a substitute based on matching functional classification as a 4-20mA current transmitter, compatible supply current specifications, and equivalent package requirements. Both components serve the same interface function within industrial measurement and control applications.

Engineering Selection Recommendations

The XTR112U represents the primary substitute for the obsolete XTR114U. Selection between these components should be based on the following factors:

XTR114U (Original): Suitable for existing inventory management and legacy system repairs where original component specifications are required. ROHS3 compliance is verified. Product status is obsolete, limiting new procurement options.

XTR112U (Substitute): Recommended for new designs and ongoing production support due to active product status. Manufactured by Burr Brown, this component maintains functional equivalence as a 4-20mA current transmitter. Both components share identical ECCN and HTSUS classifications, confirming regulatory alignment. The 14-SOIC package format ensures mechanical and electrical compatibility with existing PCB layouts designed for the XTR114U.

Frequently Asked Questions (FAQ)

Q: Can the XTR112U directly replace the XTR114U in existing designs?

A: Yes. Both components are 14-SOIC surface mount current transmitters with 20 mA supply current specifications. The XTR112U maintains functional equivalence for voltage input to voltage output signal conversion applications. PCB layout and footprint compatibility is preserved.

Q: Why is the XTR114U listed as obsolete?

A: Obsolete status indicates the component is no longer manufactured by Texas Instruments. The XTR112U by Burr Brown provides continued availability for equivalent functionality.

Q: Are there compliance differences between the XTR114U and XTR112U?

A: Both components share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications. The XTR114U specifies ROHS3 compliance; RoHS status for the XTR112U is not provided in available documentation.

Q: What is the moisture sensitivity level for these components?

A: The XTR114U has MSL 3 rating (168 hours). Moisture sensitivity data for the XTR112U is not specified in the provided parameters.

Q: Are both components suitable for -40°C to 85°C operating temperature applications?

A: The XTR114U explicitly covers -40°C to 85°C. Operating temperature specifications for the XTR112U are not provided in the available data.
