Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSNR151-002 is determined by strict equivalence across the following critical parameters:

• Sensor Type: Hall Effect, Closed Loop technology
• Current Rating: 200A sensing capability
• Channel Configuration: Single channel
• Measurement Type: AC/DC bidirectional
• Output Characteristics: Ratiometric, Current output
• Electrical Specifications: ±12V ~ 15V supply voltage, ±0.5% accuracy, 0.5µs response time, 14mA maximum supply current
• Environmental Compliance: RoHS Compliant, MSL 1 (Unlimited)
• Physical Form: Through-hole module with single pass-through configuration

The CSNR161 meets all substitution criteria as an active product within the same CSN series, maintaining identical electrical performance parameters and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The CSNR161 is the direct equivalent substitute for the obsolete CSNR151-002. Both components are manufactured by Honeywell Sensing and Productivity Solutions within the CSN series and maintain complete electrical and mechanical parameter equivalence. The CSNR161 holds active product status, ensuring ongoing availability and manufacturer support.

Selection of the CSNR161 is appropriate for:

• Direct replacement in existing designs currently using CSNR151-002
• New designs requiring 200A Hall Effect closed-loop current sensing with AC/DC measurement capability
• Applications requiring RoHS compliance and MSL 1 moisture sensitivity rating
• Systems operating within -40°C to 85°C temperature range with ±12V to ±15V supply voltage

The packaging difference (CSNR151-002 supplied in standard packaging versus CSNR161 in bulk packaging) does not affect electrical or mechanical compatibility. Both components are through-hole mounted modules with identical single pass-through configurations.
