Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSRN2512FKR430 is determined by strict alignment of the following parameters:

• Resistance value: 430 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

The RLP73K3AR43FTDF from TE Connectivity Passive Product meets all these electrical and mechanical specifications, making it a direct substitute for the CSRN2512FKR430.

Parameter Comparison

Engineering Selection Recommendations

Both the CSRN2512FKR430 and RLP73K3AR43FTDF are active production parts with ROHS3 compliance and MSL 1 rating. The RLP73K3AR43FTDF is available in higher inventory (2934 pieces) compared to the CSRN2512FKR430 (980 pieces). The maximum seated height differs by 0.005" (0.14mm), with the TE Connectivity part measuring 0.033" versus the Stackpole part at 0.028". This dimensional variance must be evaluated against specific PCB layout and assembly constraints. Both parts carry identical electrical specifications and temperature performance characteristics suitable for automotive current sense applications.

Frequently Asked Questions (FAQ)

Q: Can RLP73K3AR43FTDF replace CSRN2512FKR430 in automotive applications?

A: Yes. Both parts meet AEC-Q200 requirements, carry ROHS3 compliance, and share identical electrical specifications including 430 mOhms resistance, ±1% tolerance, 2W power rating, and ±200ppm/°C temperature coefficient across the -55°C to 155°C operating range.

Q: What is the difference in physical dimensions between these parts?

A: Both parts use the 2512 (6432 Metric) package with identical length (0.250") and width (0.124"). The maximum seated height differs: CSRN2512FKR430 is 0.028" (0.70mm) and RLP73K3AR43FTDF is 0.033" (0.84mm). This 0.005" difference may impact PCB clearance in space-constrained designs.
