Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CSR1206FT24L0 are qualified based on the following critical parameters:

• Resistance value: 24 mOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.5W / 1/2W (exact match required)
• Package: 1206 (3216 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Features: Current Sense (exact match required)
• Operating temperature range: -55°C ~ 155°C (minimum requirement)
• RoHS3 compliance (required for regulatory equivalence)
• Moisture Sensitivity Level: 1 (Unlimited) (required for storage and handling equivalence)

The RLP73M2BR024FTDF from TE Connectivity Passive Product meets all mandatory substitution criteria. Dimensional variations within manufacturing tolerances and temperature coefficient differences do not affect functional equivalence for current sense applications within specified operating conditions.

Parameter Comparison

Engineering Selection Recommendations

Both the CSR1206FT24L0 and RLP73M2BR024FTDF are Active products with full RoHS3 compliance and REACH unaffected status. Selection between these parts is based on availability and supply chain requirements rather than functional differences. The CSR1206FT24L0 features a lower temperature coefficient (±100ppm/°C) compared to the RLP73M2BR024FTDF (±400ppm/°C); however, both remain within acceptable performance parameters for current sense applications across the specified operating temperature range of -55°C to 155°C. Dimensional differences (0.05mm in length) fall within standard PCB layout tolerances for 1206 package footprints. Both parts maintain identical electrical specifications for resistance, tolerance, power rating, and package configuration, ensuring direct functional equivalence in circuit applications.

Frequently Asked Questions (FAQ)
