RLP73N1JR36FTDF Equivalent & Substitute Parts

Part Overview

The RLP73N1JR36FTDF is a 360 mOhms ±1% thick film chip resistor manufactured by TE Connectivity Passive Product, rated at 0.125W (1/8W) in a 0603 (1608 Metric) surface mount package. This component is designed for current sensing applications and is classified as Active product status. The part is RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained within the allowed specifications for this product category. Substitutes must match the core resistance value, tolerance, package form factor, and functional application while meeting or exceeding the original part's performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RLP73N1JR36FTDF are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 360 mOhms
• Tolerance: ±1%
• Composition: Thick Film
• Application: Current Sense

Mechanical Parameters (Must Match):

• Package / Case: 0603 (1608 Metric)
• Number of Terminations: 2
• Supplier Device Package: 0603

Environmental & Compliance Parameters (Must Match or Exceed):

• Operating Temperature Range: -55°C ~ 155°C (minimum)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

Power Rating Consideration: Substitute parts with equal or higher power ratings (0.125W or greater) are acceptable. The identified substitutes feature 0.2W (1/5W) ratings, which exceed the original specification and provide enhanced thermal performance margin.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain full electrical and mechanical compatibility with the RLP73N1JR36FTDF while providing enhanced performance characteristics.

RCWE0603R360FKEA (Vishay Dale): This substitute offers a 0.2W power rating with improved temperature coefficient performance (±100ppm/°C versus ±300ppm/°C). The part includes Automotive AEC-Q200 qualification and moisture-resistant thick film construction. All compliance requirements are met: ROHS3 compliant, MSL 1, and REACH unaffected. This part is suitable for applications requiring automotive-grade reliability and enhanced thermal margin.

UCR03EVPFLR360 (Rohm Semiconductor): This substitute provides a 0.2W power rating with superior temperature coefficient performance (0/+150ppm/°C). Automotive AEC-Q200 qualification is included. All compliance requirements are satisfied: ROHS3 compliant, MSL 1, and REACH unaffected. This part is appropriate for applications requiring automotive-grade qualification and tighter temperature stability.

Both substitutes are Active status products with established supply availability. Selection between substitutes depends on specific application requirements regarding temperature coefficient performance and automotive qualification needs.

Frequently Asked Questions (FAQ)

Q: Can RCWE0603R360FKEA or UCR03EVPFLR360 be used as direct replacements for RLP73N1JR36FTDF?

A: Yes. Both substitute parts maintain identical resistance (360 mOhms), tolerance (±1%), package form factor (0603), and current sense application. All three parts operate across the same temperature range (-55°C ~ 155°C) and meet ROHS3 compliance and MSL 1 requirements. The substitutes feature higher power ratings (0.2W versus 0.125W), which provide additional thermal performance margin without affecting circuit operation.

Q: What is the difference in temperature coefficient between these parts?

A: The RLP73N1JR36FTDF has a temperature coefficient of ±300ppm/°C. The RCWE0603R360FKEA offers ±100ppm/°C, and the UCR03EVPFLR360 provides 0/+150ppm/°C. Lower temperature coefficients indicate better resistance stability across temperature variations. Applications requiring tighter resistance tolerance over temperature should prioritize substitutes with lower temperature coefficient values.

Q: Are the physical dimensions compatible for PCB layout?

A: All three parts use the 0603 (1608 Metric) package with identical length (0.063" / 1.60mm). Width and height dimensions vary slightly: RLP73N1JR36FTDF is 0.031" W × 0.022" H; RCWE0603R360FKEA is 0.033" W × 0.024" H; UCR03EVPFLR360 is 0.034" W × 0.024" H. These dimensional variations are within standard 0603 package tolerances and do not affect PCB footprint compatibility.

Q: Do the substitute parts have automotive qualification?

A: Both RCWE0603R360FKEA and UCR03EVPFLR360 carry Automotive AEC-Q200 qualification. The original RLP73N1JR36FTDF does not list AEC-Q200 qualification. Applications requiring automotive-grade components should use one of the qualified substitutes.

Q: What is the moisture sensitivity rating for all three parts?

A: All three parts have MSL 1 (Unlimited) moisture sensitivity level, indicating no moisture sensitivity restrictions. These parts can be stored and handled without special moisture control measures.

Q: Are all parts RoHS3 compliant?

A: Yes. RLP73N1JR36FTDF, RCWE0603R360FKEA, and UCR03EVPFLR360 are all ROHS3 compliant and REACH unaffected, meeting current environmental regulations for electronic components.
