Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CSR0805JTR910 are qualified based on the following electrical and mechanical parameters:

Critical Parameters for Substitution:

• Resistance value: 910 mOhms (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Power rating: 0.25W minimum
• Composition: Thick Film
• Features: Current Sense capability
• Temperature Coefficient: ±200ppm/°C
• Operating Temperature Range: -55°C ~ 155°C minimum
• RoHS Status: ROHS3 Compliant

Tolerance Consideration: Tolerance is a parameter that may vary between the main part and substitutes. The main part specifies ±5% tolerance. Substitute parts with tighter tolerance (±1%) are considered upgrades and are fully compatible, as they meet or exceed the electrical requirements of the original specification.

Two substitute parts are identified:

1. RLP73K2AR91JTD - Direct equivalent with matching ±5% tolerance
2. RLP73K2AR91FTDF - Upgrade option with tighter ±1% tolerance
