CSR1206FT75L0 Equivalent & Substitute Parts

Part Overview

The CSR1206FT75L0 is a 75 milliohm, ±1% tolerance, 0.5W thick film chip resistor in 1206 (3216 Metric) package manufactured by Stackpole Electronics Inc. This current sense resistor is designed for precision low-resistance applications requiring stable performance across industrial temperature ranges. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and compliance certifications align with the original component, enabling direct replacement in circuit designs without performance degradation.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment of the following parameters:

Resistance value: 75 mOhms
Tolerance: ±1%
Power rating: 0.5W
Package: 1206 (3216 Metric)
Composition: Thick Film
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C to 155°C

Engineering Selection Recommendations

CSR1206FK75L0 provides direct substitution with identical specifications and dimensions. Both parts are manufactured by Stackpole Electronics Inc and maintain Active product status with full RoHS3 compliance.

RCWE120675L0FKEA serves as an upgrade substitute for applications requiring automotive-grade reliability. This part carries AEC-Q200 qualification and includes moisture-resistant features. Dimensional variations are minor: length increases by 0.002" (0.05mm), width by 0.002" (0.05mm), and height by 0.002" (0.05mm). These tolerances remain within standard PCB layout margins for 1206 package footprints. Selection of this part is appropriate for automotive, industrial, or high-reliability applications where enhanced environmental protection is specified.

Frequently Asked Questions (FAQ)
