Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSR2512FTR470 is determined by the following parameters:

• Resistance value: 470 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

Two substitute parts meet these criteria. CSRN2512FKR470 is a Stackpole Electronics variant with identical electrical specifications and adds AEC-Q200 automotive qualification. RLP73K3AR47FTDF is manufactured by TE Connectivity Passive Product with matching electrical and thermal characteristics.

Parameter Comparison

Engineering Selection Recommendations

All three parts are active products with ROHS3 compliance and identical electrical specifications. Selection between them depends on application context:

CSRN2512FKR470 includes AEC-Q200 automotive qualification, making it suitable for automotive and high-reliability applications requiring enhanced qualification standards. This part carries higher inventory availability (79,436 pcs).

RLP73K3AR47FTDF from TE Connectivity Passive Product provides an alternative source for supply chain diversification. It maintains all electrical and thermal specifications with equivalent performance characteristics.

CSR2512FTR470 remains the baseline specification for general industrial applications without automotive requirements.

Frequently Asked Questions (FAQ)

Q: Can CSRN2512FKR470 replace CSR2512FTR470 in non-automotive applications?

A: Yes. CSRN2512FKR470 meets all electrical, thermal, and compliance specifications of CSR2512FTR470. The AEC-Q200 qualification is an additional feature that does not restrict use in non-automotive circuits.

Q: Are there mechanical compatibility differences between these parts?

A: All three parts use the 2512 (6432 Metric) package. Dimensional variations exist within tolerance: CSR2512FTR470 measures 0.252" L x 0.126" W with 0.026" max height; CSRN2512FKR470 measures 0.250" L x 0.124" W with 0.028" max height; RLP73K3AR47FTDF measures 0.250" L x 0.124" W with 0.033" max height. These differences fall within standard PCB footprint tolerances for 2512 packages.

Q: Do all parts have identical temperature performance?

A: Yes. All three parts share ±200ppm/°C temperature coefficient and -55°C to 155°C operating range, ensuring equivalent thermal performance in circuit applications.

Q: What is the moisture sensitivity implication?

A: All parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage practices apply without special desiccant requirements.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes, provided the PCB footprint accommodates the maximum dimensional variations listed. Verify footprint compatibility with the specific height and length specifications of the selected substitute before assembly.
