CSR0805FTR100 Equivalent & Substitute Parts

Part Overview

The CSR0805FTR100 is a 100 mOhms ±1% 0.25W thick film chip resistor in 0805 (2012 Metric) package manufactured by Stackpole Electronics Inc. This current sense resistor is designed for precision low-resistance applications requiring tight tolerance and stable performance across industrial temperature ranges. The part is Active status and ROHS3 compliant. Substitute parts are necessary when primary inventory is unavailable, when design requirements demand enhanced automotive qualification, or when higher power dissipation capability is required for thermal margin.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following mandatory parameters:

• Resistance value: 100 mOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Features: Current Sense (required)
• Operating Temperature Range: Minimum -55°C, Maximum ≥155°C
• RoHS Status: ROHS3 Compliant (required)
• Moisture Sensitivity Level: 1 (Unlimited) (required)

Power rating may vary within acceptable limits for the application. Temperature coefficient and automotive qualification (AEC-Q200) are secondary parameters that may differ between substitutes. All substitute parts listed meet the core electrical and mechanical requirements for direct substitution in standard applications.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are Active status products with ROHS3 compliance and MSL 1 rating, meeting the core requirements for direct substitution with the CSR0805FTR100.

CSR0805FKR100 (Stackpole Electronics Inc) provides identical electrical and mechanical specifications as the main part, differing only in packaging designation. This is the primary direct substitute.

ERJ-6BWFR100V (Panasonic Electronic Components) offers increased power dissipation at 0.5W with AEC-Q200 automotive qualification. Select this part when thermal margin is required or when automotive-grade reliability is specified.

ERJ-L06KF10CV (Panasonic Electronic Components) provides AEC-Q200 automotive qualification with improved temperature coefficient (±100ppm/°C) but operates to 125°C maximum. Select only when maximum operating temperature does not exceed 125°C and automotive qualification is required.

PT0805FR-7W0R1L (YAGEO) combines 0.25W power rating with AEC-Q200 automotive qualification and moisture-resistant composition. Operating temperature extends to 155°C. Select when automotive qualification and moisture resistance are required.

UCR10EVHFLR100 (Rohm Semiconductor) provides intermediate power rating (0.333W) with AEC-Q200 automotive qualification and extended temperature coefficient range (0 / +150ppm/°C). Select when moderate power margin and automotive qualification are needed.

Frequently Asked Questions (FAQ)

Q: Can CSR0805FKR100 replace CSR0805FTR100 without design changes?

A: Yes. Both parts share identical resistance (100 mOhms), tolerance (±1%), power rating (0.25W), package (0805), composition (Thick Film), operating temperature range (-55°C ~ 155°C), and compliance ratings (ROHS3, MSL 1). The difference is packaging designation only.

Q: When should I select ERJ-6BWFR100V instead of the main part?

A: Select ERJ-6BWFR100V when your circuit requires higher power dissipation capability (0.5W vs 0.25W) or when AEC-Q200 automotive qualification is mandatory. All other electrical parameters remain compatible.

Q: Is ERJ-L06KF10CV suitable for applications requiring 155°C operation?

A: No. ERJ-L06KF10CV operates to 125°C maximum, which is below the CSR0805FTR100 specification of 155°C. Use this part only when maximum operating temperature does not exceed 125°C.

Q: What is the difference between temperature coefficient specifications?

A: Temperature coefficient indicates resistance change per degree Celsius. CSR0805FTR100 specifies ±200ppm/°C. Substitutes with lower coefficients (±100ppm/°C or 0/+150ppm/°C) provide better stability across temperature extremes. Higher coefficients are acceptable for applications with moderate temperature variation.

Q: Do all substitute parts maintain the same physical dimensions?

A: All parts use 0805 (2012 Metric) package with identical length (0.079" / 2.00mm) and width (0.049" / 1.25mm). Height varies slightly: CSR0805FTR100 and PT0805FR-7W0R1L at 0.026" (0.65mm), ERJ-L06KF10CV at 0.028" (0.70mm), ERJ-6BWFR100V at 0.030" (0.75mm), and UCR10EVHFLR100 at 0.026" (0.65mm). These variations are within standard PCB assembly tolerances.

Q: Which substitute offers the best overall compatibility?

A: CSR0805FKR100 provides identical specifications to the main part. For applications requiring automotive qualification, PT0805FR-7W0R1L offers the most balanced feature set with AEC-Q200 rating, 0.25W power, and full 155°C operating range.

Q: Are all parts available in Tape & Reel packaging?

A: CSR0805FTR100, CSR0805FKR100, ERJ-6BWFR100V, ERJ-L06KF10CV, and UCR10EVHFLR100 are supplied in Tape & Reel (TR). PT0805FR-7W0R1L is supplied in Cut Tape (CT) & Digi-Reel®. Verify packaging requirements for your procurement process.
