CSR0603FKR360 Equivalent & Substitute Parts

Part Overview

The CSR0603FKR360 is a 360 mOhms ±1% thick film chip resistor in 0603 (1608 Metric) package rated for 0.125W (1/8W) power dissipation. Manufactured by Stackpole Electronics Inc, this current sense resistor operates across -55°C to 155°C with a temperature coefficient of ±300ppm/°C. The part is ROHS3 compliant and carries MSL 1 (Unlimited) moisture sensitivity rating. As an active product with 803 units in stock, equivalent substitutes may be required for supply chain continuity, design flexibility, or regional availability considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSR0603FKR360 is determined by strict equivalence across the following critical parameters:

• Resistance value: 360 mOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0603 (1608 Metric)
• Composition: Thick Film
• Current sense functionality
• Temperature coefficient: ±300ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3
• Moisture sensitivity: MSL 1

Only parts matching all these parameters across electrical, thermal, mechanical, and environmental specifications qualify as direct substitutes. Manufacturer differences do not affect substitution validity when all parameters align.

Parameter Comparison

Engineering Selection Recommendations

The RLP73N1JR36FTDF manufactured by TE Connectivity Passive Product is a direct equivalent to the CSR0603FKR360. Both parts maintain identical electrical specifications, thermal performance, mechanical dimensions, and regulatory compliance. Selection between these parts may be based on supply availability, lead time, or procurement preferences. The RLP73N1JR36FTDF currently has 1330 units in stock compared to 803 units for the CSR0603FKR360. Both parts are active products with ROHS3 compliance and REACH Unaffected status, suitable for applications requiring current sensing in the 360 mOhms range across extended temperature environments.

Frequently Asked Questions (FAQ)

Q: Can the RLP73N1JR36FTDF replace the CSR0603FKR360 in my design?

A: Yes. The RLP73N1JR36FTDF is a direct substitute. All electrical parameters (360 mOhms ±1%), power rating (0.125W), package dimensions (0603), thermal characteristics (±300ppm/°C, -55°C ~ 155°C), and regulatory certifications (ROHS3, REACH Unaffected) are identical.

Q: Are there any mechanical compatibility concerns?

A: No. Both parts share identical package specifications: 0603 (1608 Metric) with dimensions of 0.063" L x 0.031" W (1.60mm x 0.80mm) and maximum seated height of 0.022" (0.55mm). PCB footprints and assembly processes remain unchanged.

Q: What determines substitution eligibility for this resistor?

A: Substitution requires matching across all parameters: 360 mOhms resistance, ±1% tolerance, 0.125W power rating, 0603 package, thick film composition, current sense functionality, ±300ppm/°C temperature coefficient, -55°C ~ 155°C operating range, and ROHS3 compliance. Deviation in any parameter disqualifies a part as a direct substitute.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both the CSR0603FKR360 and RLP73N1JR36FTDF carry MSL 1 (Unlimited) moisture sensitivity level, indicating no moisture-related handling restrictions.

Q: Are there supply or availability differences?

A: The RLP73N1JR36FTDF has higher current inventory (1330 units) compared to the CSR0603FKR360 (803 units). Both are active products with standard Tape & Reel packaging.
