Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSRN2512FT30L0 is determined by the following critical parameters:

• Resistance value: 30 mOhms
• Tolerance: ±1%
• Power rating: 2W
• Package footprint: 2512 (6432 Metric)
• Termination count: 2
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

The PR2512FKE7W0R03Z from YAGEO meets all these core electrical and mechanical requirements. While composition differs (metal element vs. thick film) and temperature coefficient is superior (±50ppm/°C vs. ±200ppm/°C), the substitute maintains functional equivalence for current sense applications within the specified operating temperature range of -55°C to 170°C.

Parameter Comparison

Engineering Selection Recommendations

Both CSRN2512FT30L0 and PR2512FKE7W0R03Z are active production parts with ROHS3 compliance and unlimited moisture sensitivity ratings. The CSRN2512FT30L0 carries AEC-Q200 automotive qualification, while the PR2512FKE7W0R03Z does not list this certification in the provided specifications. Selection between these parts should be based on specific automotive qualification requirements for the application. The YAGEO substitute offers improved temperature coefficient performance and extended upper operating temperature limit, which may provide advantages in high-temperature environments. Dimensional variations are minimal and within typical PCB layout tolerances for 2512 package footprints.

Frequently Asked Questions (FAQ)

Q: Can PR2512FKE7W0R03Z replace CSRN2512FT30L0 in automotive applications?

A: Both parts share identical electrical specifications (30 mOhms, ±1%, 2W) and package footprint (2512). However, the CSRN2512FT30L0 carries AEC-Q200 certification while the PR2512FKE7W0R03Z does not list this qualification. Substitution in automotive applications requires verification that AEC-Q200 compliance is not a mandatory requirement for your specific design.

Q: What are the dimensional differences between these parts?

A: The CSRN2512FT30L0 measures 0.250" L x 0.124" W with 0.028" maximum seated height. The PR2512FKE7W0R03Z measures 0.252" L x 0.126" W with 0.041" maximum seated height. These differences are within standard PCB layout tolerances for 2512 packages but should be confirmed for space-constrained designs.

Q: How do the temperature coefficients compare?

A: The CSRN2512FT30L0 has a temperature coefficient of ±200ppm/°C, while the PR2512FKE7W0R03Z offers ±50ppm/°C. The YAGEO part provides superior temperature stability across the operating range.

Q: Are both parts RoHS compliant?

A: Yes, both CSRN2512FT30L0 and PR2512FKE7W0R03Z are ROHS3 compliant with unlimited moisture sensitivity levels (MSL 1).

Q: What is the difference between thick film and metal element composition?

A: The CSRN2512FT30L0 uses thick film construction while the PR2512FKE7W0R03Z uses metal element construction. Both compositions achieve the specified 30 mOhms resistance and ±1% tolerance. Metal element construction typically provides better temperature stability, as reflected in the lower temperature coefficient of the YAGEO part.
