CS3FR010 Equivalent & Substitute Parts

Part Overview

The CS3FR010 is a 10 mOhms ±1% 3W through-hole resistor in 4-SIP package configuration, designed for current sense applications. It features a non-inductive metal element construction with moisture resistance and operates across -55°C to 150°C. The CS3FR010 is classified as obsolete, making identification of suitable substitutes essential for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CS3FR010 is determined by strict equivalence across the following parameters:

• Resistance value: 10 mOhms
• Tolerance: ±1%
• Power rating: 3W
• Package configuration: 4-SIP
• Composition: Metal Element
• Temperature coefficient: ±60ppm/°C
• Operating temperature range: -55°C to 150°C
• Functional features: Current sense, moisture resistant, non-inductive

The CS3FR010E meets all substitution criteria as a direct equivalent from the same manufacturer (Ohmite) within the CS3 series. The primary distinction is product status and compliance certification, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The CS3FR010E is the direct substitute for the obsolete CS3FR010. Both components are electrically and mechanically identical across all specified parameters. The CS3FR010E is classified as active product status, ensuring continued availability and supply chain support.

The CS3FR010E carries ROHS3 compliance certification, whereas the CS3FR010 is RoHS non-compliant. Both maintain REACH Unaffected status and identical ECCN/HTSUS classifications. Selection between these parts should be based on regulatory requirements and supply chain continuity needs.

Frequently Asked Questions (FAQ)
