HAC 300-S Hall Effect Current Sensor Equivalent & Substitute Parts

Part Overview

The HAC 300-S is an active Hall Effect current sensor manufactured by LEM USA Inc., designed for bidirectional AC/DC current measurement applications. This open-loop module provides ratiometric voltage output with a 300A sensing range and operates across industrial temperature ranges. The part is currently in active production status with full RoHS compliance and REACH unaffected classification. Substitute parts are identified when equivalent electrical and mechanical parameters allow direct functional replacement within system designs, particularly when inventory availability or application-specific current rating requirements necessitate alternative models from the same product series.

Substitute Part Grouping Explanation

Substitution eligibility for the HAC 300-S is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Sensor Type: Hall Effect, Open Loop
• Output Type: Ratiometric, Voltage
• Number of Channels: 1
• Frequency Response: DC ~ 50kHz
• Linearity: ±1%
• Accuracy: ±1%
• Supply Voltage: ±15V
• Response Time: 7µs
• Maximum Supply Current: 18mA
• Operating Temperature Range: -10°C ~ 80°C
• Polarization: Bidirectional
• Mounting Type: Chassis Mount
• Package Type: Module
• RoHS Status: RoHS Compliant
• Manufacturer: LEM USA Inc.
• Series: HAC

Variable Parameter (Substitution Basis):

• Current Sensing Range: 300A (main part) vs. 200A (substitute)

The HAC 200-S qualifies as a parametric equivalent substitute because it maintains identical electrical characteristics, mechanical form factor, and compliance certifications. The reduced current sensing range (200A vs. 300A) represents the only technical difference and is application-dependent. This substitution is valid for applications requiring current measurement within the 200A maximum range.

Parameter Comparison

Engineering Selection Recommendations

Both the HAC 300-S and HAC 200-S are active production components manufactured by LEM USA Inc. with identical RoHS compliance and REACH unaffected status. Selection between these parts is determined solely by the maximum current measurement requirement of the application.

HAC 300-S Selection Criteria:

• Applications requiring current measurement up to 300A
• Systems where future current capacity expansion is anticipated
• Designs with no current range constraints

HAC 200-S Selection Criteria:

• Applications with maximum current requirements up to 200A
• Cost-optimized designs where 200A capacity is sufficient
• Systems where inventory availability of the 200A variant is advantageous

Both parts share identical electrical performance characteristics, mechanical mounting interfaces, and environmental operating specifications. The substitution decision is application-specific and based on the maximum current measurement range required by the system design.

Frequently Asked Questions (FAQ)

Q: Can the HAC 200-S replace the HAC 300-S in all applications?

A: The HAC 200-S is a parametric equivalent substitute only for applications where the maximum measured current does not exceed 200A. If the application requires current measurement capability above 200A, the HAC 300-S is the appropriate selection. All other electrical and mechanical characteristics are identical.

Q: Are the output voltage signals compatible between HAC 300-S and HAC 200-S?

A: Both parts provide ratiometric voltage output with identical linearity (±1%) and accuracy (±1%) specifications. The output voltage scaling differs proportionally to the current sensing range. System signal conditioning and calibration must account for the specific current range of the selected part.

Q: Do both parts require identical power supply specifications?

A: Yes. Both the HAC 300-S and HAC 200-S require ±15V supply voltage with maximum supply current of 18mA. Power supply design and filtering requirements are identical for both parts.

Q: Are the mounting interfaces identical between these parts?

A: Yes. Both parts are chassis mount modules with identical package types. Mechanical mounting and PCB layout considerations are identical.

Q: What is the frequency response capability of both sensors?

A: Both the HAC 300-S and HAC 200-S provide DC to 50kHz frequency response with 7µs response time, enabling measurement of AC and DC currents across industrial frequency ranges.

Q: Are both parts suitable for bidirectional current measurement?

A: Yes. Both parts feature bidirectional polarization, allowing measurement of current flow in both directions without modification to the circuit design.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the HAC 300-S and HAC 200-S are RoHS compliant and REACH unaffected, meeting identical regulatory requirements for industrial and commercial applications.
