Parameter Comparison

Engineering Selection Recommendations

The CGSSL1R01J is the direct equivalent substitute for the obsolete SL1R01J. Both components are manufactured by TE Connectivity Passive Product and share identical electrical, mechanical, and material specifications.

Selection Basis:

The CGSSL1R01J is recommended for new designs and production continuity because it maintains active product status with TE Connectivity, ensuring long-term availability and supply chain stability. The component carries identical RoHS3 compliance and environmental certifications as the original part.

The primary distinction between the two parts is packaging format. The SL1R01J is supplied in standard packaging, while the CGSSL1R01J is supplied in Tape & Reel (TR) format, which is standard for high-volume manufacturing operations. This packaging difference does not affect electrical or mechanical performance.

Both parts are suitable for current sense applications requiring precision measurement in the 10 milliohm range with 1-watt power dissipation capability.
