Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSR2512FT15L0 is determined by strict equivalence across the following parameters: resistance value (15 mOhms), tolerance (±1%), power rating (2W), package type (2512), composition (thick film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, REACH Unaffected). The identified substitute parts CSRN2512FK15L0 and CSRN2512FT15L0 maintain all critical electrical specifications and mechanical compatibility. Both substitute parts are manufactured by Stackpole Electronics Inc and carry AEC-Q200 automotive qualification, which represents an enhanced reliability rating beyond the base CSR2512FT15L0 specification.

Parameter Comparison

Engineering Selection Recommendations

The CSR2512FT15L0 and its substitute parts CSRN2512FK15L0 and CSRN2512FT15L0 are electrically and mechanically interchangeable for applications requiring 15 mOhms ±1% current sense resistors in 2512 package format. All three parts maintain Active product status and full ROHS3 compliance. The CSRN series substitutes carry AEC-Q200 automotive qualification, indicating enhanced reliability screening and qualification per automotive standards. Selection between the base CSR2512FT15L0 and CSRN variants depends on application requirements: use CSR2512FT15L0 for general industrial applications, or specify CSRN2512FK15L0 or CSRN2512FT15L0 when automotive-grade reliability and qualification documentation are required. Dimensional variations between parts (CSR: 0.252" L x 0.126" W vs. CSRN: 0.250" L x 0.124" W) fall within standard PCB layout tolerances for 2512 package footprints.

Frequently Asked Questions (FAQ)

Q: Are CSRN2512FK15L0 and CSRN2512FT15L0 functionally identical? A: Both CSRN variants maintain identical electrical specifications (15 mOhms ±1%, 2W, ±200ppm/°C, -55°C to 155°C). Both carry AEC-Q200 automotive qualification. The primary difference is packaging format: FK denotes one tape configuration while FT denotes another, both supplied as Tape & Reel (TR).

Q: Can CSR2512FT15L0 be replaced with CSRN2512FT15L0 in existing designs? A: Yes. Both parts share identical electrical parameters, tolerance, power rating, temperature range, and package designation (2512). The CSRN variant provides equivalent or enhanced performance with automotive-grade qualification. Dimensional tolerances are within standard PCB footprint specifications.

Q: What is the significance of AEC-Q200 rating on substitute parts? A: AEC-Q200 is an automotive industry qualification standard indicating the component has undergone enhanced reliability testing and screening. Parts carrying this rating are suitable for automotive applications requiring documented quality assurance. Non-automotive applications can use either CSR or CSRN variants.

Q: Are there mechanical compatibility concerns when substituting between CSR2512FT15L0 and CSRN variants? A: Minor dimensional differences exist (height: CSR 0.026" max vs. CSRN 0.028" max; length/width within 0.002" tolerance). These variations are within standard 2512 package specifications and do not affect PCB layout or soldering processes.

Q: Do all three parts meet the same compliance requirements? A: Yes. CSR2512FT15L0, CSRN2512FK15L0, and CSRN2512FT15L0 all comply with ROHS3, carry REACH Unaffected status, and share identical ECCN (EAR99) and HTSUS (8533.21.0030) classifications.
