Frequently Asked Questions (FAQ)

Q: Can CSRN2512FK68L0 be used as a direct replacement for CSR2512FT68L0?

A: Yes. Both parts share identical electrical specifications (68 mOhms ±1%, 2W, ±200ppm/°C) and mechanical package configuration (2512 / 6432 Metric). The CSRN variant includes additional AEC-Q200 automotive qualification but does not alter core performance parameters.

Q: What is the difference between CSR and CSRN series designations?

A: The CSRN series includes automotive AEC-Q200 qualification. Both series use identical thick film composition and thermal characteristics. The series designation reflects qualification level rather than electrical performance differences.

Q: Are the physical dimensions identical between these parts?

A: Both parts use the 2512 (6432 Metric) package. Minor dimensional variations exist within manufacturing tolerance: CSR2512FT68L0 is 0.252" L x 0.126" W with 0.026" max height; CSRN2512FK68L0 is 0.250" L x 0.124" W with 0.028" max height. These variations remain within standard PCB footprint specifications for 2512 packages.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For automotive applications or designs requiring AEC-Q200 compliance, specify CSRN2512FK68L0. For general industrial applications, either part is acceptable based on availability and cost considerations.

Q: Are both parts RoHS compliant?

A: Yes. Both CSR2512FT68L0 and CSRN2512FK68L0 are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).
