Substitute Part Grouping Explanation

Substitution eligibility for the CSR0805FKR274 is determined by strict equivalence across the following critical parameters:

• Resistance value: 274 mOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The substitute part CSR0805FTR274 maintains identical electrical and mechanical specifications. The only distinction is the packaging format: the main part uses Tape & Reel (TR) packaging with 738 pieces in stock, while the substitute uses Tape & Reel (TR) packaging with 1753 pieces in stock. Both parts are manufactured by Stackpole Electronics Inc and carry Active product status.

Parameter Comparison

Engineering Selection Recommendations

Both CSR0805FKR274 and CSR0805FTR274 are functionally equivalent for circuit applications requiring 274 mOhms ±1% current sense resistors in 0805 package format. Selection between these parts should be based on inventory availability and supply chain requirements. Both parts maintain Active product status, ROHS3 compliance, and REACH unaffected designation, ensuring regulatory compatibility in manufacturing environments subject to these standards. The CSR0805FTR274 offers higher inventory availability at 1753 pieces compared to 738 pieces for the CSR0805FKR274, which may influence procurement decisions for volume production schedules.
