Key Parameters

Substitute Part Grouping Explanation

The CSR0805FKR200 qualifies as a direct substitute based on identical electrical and mechanical parameters. Substitution is valid when all of the following criteria are met:

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

The CSR0805FKR200 meets all these criteria and is manufactured by the same supplier, ensuring functional and mechanical interchangeability in circuit applications.
