CSR0603FKR160 Equivalent & Substitute Parts

Part Overview

The CSR0603FKR160 is a 160 mOhms ±1% thick film chip resistor in 0603 (1608 Metric) package rated for 0.125W (1/8W) power dissipation. Manufactured by Stackpole Electronics Inc, this current sense resistor is designed for precision low-resistance applications requiring tight tolerance and stable performance across industrial temperature ranges. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent parts are identified to support supply chain continuity, design flexibility, and inventory optimization when the primary part becomes unavailable or when alternative sourcing is preferred.

• Tolerance: ±1% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Package: 0603 (1608 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Current sense functionality (exact match required)
• Temperature coefficient: ±300ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Termination count: 2 (exact match required)
• Physical dimensions: 0.063" L x 0.031" W / 1.60mm x 0.80mm (exact match required)
• Height seated maximum: 0.022" / 0.55mm (exact match required)

The RLP73N1JR16FTDF from TE Connectivity Passive Product meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison
