Key Parameters

Substitute Part Grouping Explanation

Substitution of the RLP73M1JR075FTDF is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 75 mOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0603 (1608 Metric)
• Composition: Thick Film
• Features: Current Sense
• Operating temperature range: -55°C to 155°C
• Termination count: 2

Allowable Variation Parameters:

• Temperature coefficient: Substitute parts may vary within the range of ±300ppm/°C to ±400ppm/°C
• RoHS compliance status: Substitutes may differ in RoHS certification level
• Manufacturer identity: Different manufacturers producing equivalent specifications

The identified substitute part CSR0603FK75L0 meets all mandatory matching parameters and operates within the allowable temperature coefficient variation.

Parameter Comparison

Engineering Selection Recommendations

RLP73M1JR075FTDF (TE Connectivity Passive Product): This part is suitable for applications where RoHS non-compliance is acceptable or where legacy design specifications require TE Connectivity sourcing. The part maintains active production status and is available in inventory.

CSR0603FK75L0 (Stackpole Electronics Inc): This substitute part is suitable for applications requiring ROHS3 compliance. The CSR0603FK75L0 provides equivalent electrical performance with a lower temperature coefficient (±300ppm/°C versus ±400ppm/°C), which may provide improved stability in temperature-sensitive applications. This part maintains active production status and is available in inventory.

Both parts are functionally interchangeable within the specified electrical and mechanical parameters. Selection between them should be based on compliance requirements and sourcing preferences.

Frequently Asked Questions (FAQ)

Q: Can CSR0603FK75L0 be used as a direct replacement for RLP73M1JR075FTDF?

A: Yes. Both parts share identical resistance (75 mOhms), tolerance (±1%), power rating (0.125W), package (0603), composition (thick film), and operating temperature range (-55°C to 155°C). The parts are mechanically and electrically interchangeable.

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

A: The RLP73M1JR075FTDF has a temperature coefficient of ±400ppm/°C, while the CSR0603FK75L0 has ±300ppm/°C. Both values fall within acceptable ranges for current sense resistor applications. The lower coefficient of the Stackpole part provides marginally improved temperature stability.

Q: Are there compliance differences between these parts?

A: Yes. The RLP73M1JR075FTDF is RoHS non-compliant, while the CSR0603FK75L0 is ROHS3 compliant. Both parts are REACH unaffected and carry the same ECCN (EAR99) and HTSUS (8533.21.0030) classifications.

Q: Do these parts have identical physical dimensions?

A: Yes. Both parts measure 0.063" L x 0.031" W (1.60mm x 0.80mm) with a maximum seated height of 0.022" (0.55mm). They are pin-compatible and require no PCB layout modifications.

Q: What is the moisture sensitivity level for both parts?

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.

Q: Are both parts currently in production?

A: Yes. Both the RLP73M1JR075FTDF and CSR0603FK75L0 maintain active product status with current inventory availability.
