CSR0805FTR910 Equivalent & Substitute Parts

Part Overview

The CSR0805FTR910 is a 910 mOhms ±1% 0.25W thick film chip resistor in 0805 (2012 Metric) package 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. Substitute parts are identified when original inventory is unavailable or when supply chain requirements necessitate alternative sourcing from qualified manufacturers meeting identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the CSR0805FTR910 is determined by strict equivalence across the following critical parameters:

• Resistance value: 910 mOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Package: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Current sense functionality (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• RoHS3 compliance (exact match required)
• Moisture sensitivity level: 1 (Unlimited) (exact match required)

The RLP73K2AR91FTDF from TE Connectivity Passive Product meets all substitution criteria and is classified as a direct equivalent.
