Key Parameters

Substitute Part Grouping Explanation

Substitution of the ACS754SCB-200-PFF is determined by the following critical parameters:

• Current Rating: 200A sensing capability
• Sensor Technology: Hall Effect, Open Loop topology
• Output Configuration: Ratiometric voltage output at 10mV/A sensitivity
• Polarization: Bidirectional current measurement
• Package: 5-CB Formed Leads, PFF mechanical compatibility
• Mounting: Through Hole configuration

The ACS758ECB-200B-PFF-T meets these core substitution criteria while offering enhanced specifications and active product status. Both components share identical current sensing capacity, output type, sensitivity, polarization, and package form factor, establishing direct functional equivalence for circuit-level replacement.

Parameter Comparison

Engineering Selection Recommendations

The ACS758ECB-200B-PFF-T is the direct substitute for the obsolete ACS754SCB-200-PFF. Both components maintain identical current sensing capacity, output topology, sensitivity, polarization, and mechanical package specifications, enabling direct circuit-level replacement without redesign.

The ACS758ECB-200B-PFF-T offers the following advantages:

• Active product status with ongoing manufacturer support and availability
• ROHS3 compliance, meeting current environmental regulations
• AEC-Q100 automotive qualification for applications requiring automotive-grade reliability
• Extended operating temperature range (-40°C to 85°C versus -20°C to 85°C)
• Wider supply voltage tolerance (3V to 5.5V versus fixed 5V)
• Improved response time (4µs versus 11µs)
• Extended frequency bandwidth (DC to 120kHz versus DC to 35kHz)

Design considerations for substitution include verification that the slightly higher maximum supply current (14.6mA versus 10mA) and marginally relaxed accuracy specification (±1.2% versus ±1%) are acceptable within the application's power budget and measurement requirements.

Frequently Asked Questions (FAQ)

Q: Can the ACS758ECB-200B-PFF-T be used as a direct replacement for the ACS754SCB-200-PFF?

A: Yes. Both components share identical current sensing capacity (200A), Hall Effect open-loop topology, ratiometric voltage output (10mV/A sensitivity), bidirectional polarization, and 5-CB Formed Leads PFF package configuration. Direct substitution is supported at the circuit level without modification.

Q: What are the key differences between these two parts?

A: The primary differences are product status, compliance certifications, and performance specifications. The ACS758ECB-200B-PFF-T is an active product with ROHS3 compliance and AEC-Q100 automotive qualification. Performance improvements include extended frequency bandwidth (120kHz versus 35kHz), faster response time (4µs versus 11µs), wider supply voltage range (3V-5.5V versus 5V fixed), and extended low-temperature operating range (-40°C versus -20°C minimum).

Q: Are there any compatibility concerns with the package or mounting?

A: No. Both components use identical Through Hole mounting with 5-CB Formed Leads, PFF package specification. PCB footprints and mechanical interfaces are fully compatible.

Q: Does the substitute part require any circuit modifications?

A: No circuit modifications are required. The substitute maintains the same output sensitivity (10mV/A), supply voltage nominal value (5V), and ratiometric output behavior. The wider supply voltage tolerance of the substitute (3V-5.5V) provides additional design flexibility but does not mandate changes to existing supply circuits.

Q: What compliance advantages does the substitute offer?

A: The ACS758ECB-200B-PFF-T is ROHS3 compliant and carries AEC-Q100 automotive qualification. The original ACS754SCB-200-PFF is RoHS non-compliant and carries no specified qualification. For applications subject to environmental or automotive standards, the substitute meets current regulatory requirements.
