Substitute Part Grouping Explanation

Substitution eligibility for the CSRN2512FKR240 is determined by strict equivalence across the following parameters:

• Resistance value: 240 mOhms
• Tolerance: ±1%
• Power rating: 2W
• Package: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1 (Unlimited)

The substitute part RLP73K3AR24FTDF manufactured by TE Connectivity Passive Product meets all these electrical and mechanical parameters, qualifying it as a direct equivalent for the CSRN2512FKR240.

Parameter Comparison

Engineering Selection Recommendations

Both the CSRN2512FKR240 and RLP73K3AR24FTDF are active production parts with ROHS3 compliance and REACH unaffected status. The RLP73K3AR24FTDF is available in significantly higher inventory (56,794 pieces) compared to the CSRN2512FKR240 (989 pieces), making it suitable for high-volume applications or extended lead time mitigation. Both parts meet identical electrical specifications and automotive AEC-Q200 qualification requirements. The maximum seated height difference of 0.005" (0.14mm) between the two parts is within typical PCB design tolerances for 2512 package applications.

Frequently Asked Questions (FAQ)

Q: Can RLP73K3AR24FTDF be used as a direct replacement for CSRN2512FKR240 in automotive applications?

A: Yes. Both parts meet AEC-Q200 qualification, share identical electrical parameters (240 mOhms ±1%, 2W, ±200ppm/°C), and are packaged in the 2512 (6432 Metric) form factor. Both are ROHS3 compliant with MSL 1 rating.

Q: What is the significance of the height difference between these parts?

A: The CSRN2512FKR240 has a maximum seated height of 0.028" (0.70mm), while the RLP73K3AR24FTDF measures 0.033" (0.84mm). This 0.005" (0.14mm) difference is within standard PCB design clearances for 2512 package applications and does not affect functional compatibility.

Q: Are both parts suitable for current sense applications?

A: The CSRN2512FKR240 is explicitly rated for current sense applications. The RLP73K3AR24FTDF is also designed for current sense applications. Both parts are thick film composition resistors with identical temperature coefficients suitable for precision current measurement circuits.
