Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CSR2512FT75L0 are qualified based on the following criteria:

Electrical Parameters: Resistance value (75 mOhms), tolerance (±1%), power rating (2W), temperature coefficient (±200ppm/°C), and operating temperature range (-55°C ~ 155°C) must be identical.

Mechanical Parameters: Package type (2512 / 6432 Metric), number of terminations (2), and physical dimensions must be compatible within standard PCB assembly tolerances.

Compliance & Certifications: RoHS3 compliance and MSL rating (1) are maintained across all qualified substitutes.

The CSRN2512FK75L0 meets all substitution criteria while adding automotive-grade AEC-Q200 qualification, making it suitable for applications requiring enhanced reliability standards.

Frequently Asked Questions (FAQ)

Q: Can CSRN2512FK75L0 be used as a direct replacement for CSR2512FT75L0?

A: Yes. The CSRN2512FK75L0 meets all electrical and mechanical specifications of the CSR2512FT75L0. The primary difference is the addition of AEC-Q200 automotive qualification in the CSRN variant, which does not restrict its use in non-automotive applications.

Q: What is the significance of the AEC-Q200 rating on the CSRN2512FK75L0?

A: AEC-Q200 is an automotive industry standard qualification that certifies the component has undergone rigorous environmental stress testing, temperature cycling, and reliability validation. This rating is required for automotive applications but is not mandatory for general industrial use.

Q: Are the physical dimensions identical between these parts?

A: Both parts use the 2512 (6432 Metric) package. Minor dimensional variations exist within manufacturing tolerances: CSR2512FT75L0 is 0.252" L x 0.126" W (6.40mm x 3.20mm) with 0.026" max height, while CSRN2512FK75L0 is 0.250" L x 0.124" W (6.35mm x 3.15mm) with 0.028" max height. These differences are within standard PCB assembly tolerances and do not affect interchangeability.

Q: Do both parts have the same temperature coefficient and operating range?

A: Yes. Both parts have a temperature coefficient of ±200ppm/°C and operate across the identical temperature range of -55°C to 155°C.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level). Both carry EAR99 export classification and HTSUS code 8533.21.0030.
