Key Parameters

Substitute Part Grouping Explanation

Substitution of the SL1R068J is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part CGSSL1R068J maintains identical specifications in resistance value, tolerance, power rating, composition, package configuration, temperature coefficient, and moisture resistance characteristics. Both parts conform to the same physical dimensions (0.255" L x 0.150" W, 6.48mm x 3.81mm) and height specifications (0.112" maximum seated height, 2.84mm). The substitution is valid based on matching these core parameters: 68 mOhm resistance, ±5% tolerance, 1W power rating, metal foil construction, 2615 J-Lead package, ±100 ppm/°C temperature coefficient, and moisture-resistant design. Both parts are RoHS3 compliant and carry MSL Level 1 rating.

Engineering Selection Recommendations

The CGSSL1R068J is the direct equivalent substitute for the obsolete SL1R068J. Selection of the CGSSL1R068J is appropriate for all applications requiring a 68 milliohm, 1-watt current sense resistor with metal foil construction and moisture-resistant characteristics. The substitute part maintains full electrical and mechanical compatibility while offering active product status, ensuring long-term supply chain viability. Both parts are manufactured by TE Connectivity Passive Product and carry identical RoHS3 compliance and MSL Level 1 ratings. The primary distinction is packaging format: the substitute is supplied in Tape & Reel configuration, which is standard for high-volume production environments. No electrical performance degradation or functional compromise results from this substitution.

Frequently Asked Questions (FAQ)

Q: Can CGSSL1R068J be used as a direct replacement for SL1R068J in existing designs?

A: Yes. The CGSSL1R068J is electrically and mechanically identical to the SL1R068J across all specified parameters, including resistance value, tolerance, power rating, package dimensions, and temperature coefficient. Direct substitution is valid without design modification.

Q: What is the primary reason for substituting the SL1R068J?

A: The SL1R068J is classified as obsolete. The CGSSL1R068J provides an active equivalent part, ensuring continued availability and supply chain reliability for new production and design continuity.

Q: Are there differences in packaging between these parts?

A: The SL1R068J is supplied in standard packaging, while the CGSSL1R068J is supplied in Tape & Reel (TR) format. This difference affects handling and assembly processes but does not impact electrical or mechanical performance. Tape & Reel packaging is standard for automated assembly environments.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the SL1R068J and CGSSL1R068J are RoHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity ratings. Both are classified as EAR99 for export control purposes.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution is determined by matching resistance value (68 mOhms), tolerance (±5%), power rating (1W), composition (metal foil), package type (2615 J-Lead), temperature coefficient (±100 ppm/°C), and moisture-resistant features. All these parameters are identical between the main part and substitute.

Q: Can the CGSSL1R068J be used in current sense applications?

A: Yes. Both parts are designated as current sense resistors with identical specifications. The CGSSL1R068J maintains the same current sensing capability and accuracy characteristics as the SL1R068J.
