HTB 100-TP Current Sensor Hall Effect Equivalent & Substitute Parts

Part Overview

The HTB 100-TP is an active Hall Effect current sensor manufactured by LEM USA Inc., designed for AC/DC current measurement applications requiring 100A sensing capacity. This open-loop, bidirectional module operates with a single pass-through conductor configuration and delivers ratiometric voltage output. The product maintains Active status with RoHS compliance and REACH unaffected certification. Substitute parts are identified when application requirements permit operation at reduced current sensing ranges while maintaining compatibility across electrical, mechanical, and environmental parameters.

Substitute Part Grouping Explanation

Substitution of the HTB 100-TP is limited to the HTB 50-TP based on strict parametric compatibility within the HTB series. The substitute relationship is valid when the application current measurement requirement does not exceed 50A. Both parts share identical electrical characteristics across all parameters except current sensing capacity: identical sensor technology (Hall Effect, Open Loop), output configuration (Ratiometric Voltage), frequency response (DC ~ 50kHz), accuracy (±1%), linearity (±1%), supply voltage (±12V ~ 15V), response time (3µs), operating temperature range (-40°C ~ 80°C), polarization (Bidirectional), and mechanical configuration (Through Hole, Module, Single Pass Through).

The HTB 50-TP functions as a parametric equivalent when current sensing requirements are 50A or below. No other substitutes are provided in the reference data.

Engineering Selection Recommendations

Selection between HTB 100-TP and HTB 50-TP is determined by application current measurement requirements. The HTB 100-TP is the primary selection for applications requiring 50A to 100A current sensing. The HTB 50-TP serves as a substitute only when the maximum current to be measured does not exceed 50A.

Both parts maintain Active product status and carry identical compliance certifications: RoHS Compliant, REACH Unaffected, and EAR99 ECCN classification. Both are packaged in Bulk format and utilize identical Through Hole mounting configuration with Module, Single Pass Through mechanical design.

Electrical performance characteristics are identical across both parts: ±1% accuracy, ±1% linearity, 3µs response time, DC to 50kHz frequency response, and ±12V to 15V supply voltage operation. Operating temperature range spans -40°C to 80°C for both variants.

Frequently Asked Questions (FAQ)

Q: When is HTB 50-TP a valid substitute for HTB 100-TP?
