Parameter Comparison

Engineering Selection Recommendations

The CSNB121 is the direct parametric equivalent substitute for the obsolete CSNB131. All electrical specifications, mechanical configurations, and compliance certifications are identical between the two parts.

Selection Basis:

The CSNB121 differs from the CSNB131 only in product status: the CSNB121 is classified as Active, whereas the CSNB131 is Obsolete. This distinction is significant for supply chain planning and long-term availability assurance.

Both parts are manufactured by Honeywell Sensing and Productivity Solutions within the CSN series and maintain identical performance characteristics across all measured parameters: 100A current sensing capacity, Hall Effect closed-loop technology, AC/DC bidirectional measurement, ratiometric current output, DC to 150kHz frequency response, ±0.1% linearity, ±0.5% accuracy, ±15V supply voltage, 1µs response time, and through-hole module packaging.

Both parts carry RoHS Compliant certification and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring regulatory compliance and handling compatibility.

For new designs or production continuity, the CSNB121 is the appropriate selection due to its active product status and guaranteed long-term availability.
