Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSRN2512FTR300 is determined by strict equivalence across the following critical parameters:

• Resistance value: 300 mOhms
• Tolerance: ±1%
• Power rating: 2W
• Package: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

The RLP73K3AR30FTDF from TE Connectivity Passive Product meets all these electrical and mechanical requirements and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the CSRN2512FTR300 and RLP73K3AR30FTDF are active production parts with equivalent electrical specifications and regulatory compliance. The CSRN2512FTR300 carries AEC-Q200 automotive qualification, while the RLP73K3AR30FTDF is specified as a current sense thick film resistor without explicit AEC-Q200 designation in the provided data. Selection between these parts should be based on application-specific automotive requirements and supply availability. The RLP73K3AR30FTDF has greater inventory availability (6939 pieces versus 1041 pieces). Both parts are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements. The seated height difference of 0.005" (0.14mm) between the two parts is within typical PCB assembly tolerances for 2512 package components.

Frequently Asked Questions (FAQ)

Q: Can the RLP73K3AR30FTDF replace the CSRN2512FTR300 in automotive applications?

A: The RLP73K3AR30FTDF meets all electrical and mechanical specifications equivalent to the CSRN2512FTR300. However, the CSRN2512FTR300 carries explicit AEC-Q200 automotive qualification. Verify that your application requirements permit substitution with a part lacking explicit AEC-Q200 designation.

Q: Are there any physical compatibility issues between these two parts?

A: Both parts use the 2512 (6432 Metric) package with identical length and width dimensions (0.250" x 0.124"). The seated height differs by 0.005" (0.14mm), which is within standard PCB assembly tolerances and should not cause compatibility issues in typical applications.

Q: Do both parts meet environmental compliance requirements?

A: Both the CSRN2512FTR300 and RLP73K3AR30FTDF are ROHS3 compliant and REACH unaffected. Both carry moisture sensitivity level 1 (unlimited), indicating no special moisture handling requirements.

Q: What are the key parameters that must match for substitution?

A: Critical parameters for substitution are resistance value (300 mOhms), tolerance (±1%), power rating (2W), package type (2512), composition (thick film), temperature coefficient (±200ppm/°C), and operating temperature range (-55°C ~ 155°C).

Q: Is the tolerance specification identical between both parts?

A: Both parts specify ±1% tolerance, ensuring equivalent accuracy in current sensing applications.
