Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CSR0603FKR110 are qualified based on the following criteria:

Electrical Parameters: Resistance value of 110 mOhms with ±1% tolerance, power rating of 0.125W (1/8W), and temperature coefficient of ±300ppm/°C must be maintained.

Mechanical Compatibility: Package type 0603 (1608 Metric) with identical physical dimensions (0.063" L x 0.031" W, height 0.022" max) ensures PCB footprint compatibility.

Composition & Application: Thick film construction with current sense feature designation.

Environmental Compliance: RoHS3 compliance, MSL Level 1, and REACH Unaffected status must be preserved.

Operating Conditions: Temperature range -55°C ~ 155°C must be supported.

The identified substitute RLP73N1JR11FTDF from TE Connectivity Passive Product meets all these criteria and is qualified for direct replacement.

Parameter Comparison

Engineering Selection Recommendations

The RLP73N1JR11FTDF from TE Connectivity Passive Product is a direct electrical and mechanical equivalent to the CSR0603FKR110. Both components maintain Active product status and satisfy identical compliance requirements including ROHS3, REACH Unaffected, and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can RLP73N1JR11FTDF replace CSR0603FKR110 in existing designs?

A: Yes. Both parts share identical electrical specifications (110 mOhms ±1%, 0.125W, ±300ppm/°C), mechanical dimensions (0603 package, 1.60mm x 0.80mm), and environmental compliance ratings. PCB footprint compatibility is guaranteed.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging (CSR0603FKR110) is supplied on continuous tape for automated assembly processes. Cut Tape packaging (RLP73N1JR11FTDF) is supplied in shorter tape segments for manual or lower-volume assembly. Electrical and mechanical specifications remain identical.

Q: Are both parts suitable for current sense applications?

A: Yes. Both the CSR0603FKR110 and RLP73N1JR11FTDF are designated for current sense applications with matching thick film composition and temperature coefficient specifications.

Q: Do both parts meet RoHS and REACH requirements?

A: Yes. Both components are ROHS3 Compliant and REACH Unaffected, meeting environmental and regulatory standards for industrial and commercial applications.

Q: What is the operating temperature range for these parts?

A: Both parts operate across -55°C to 155°C, supporting applications in extended temperature environments.
