Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSRN2512FT50L0 is determined by strict equivalence across the following critical parameters:

• Resistance value: 50 mOhms
• Tolerance: ±1%
• Power rating: 2W
• Package type: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 155°C
• Number of terminations: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

The CSR2512FK50L0 meets all these criteria and is classified as a direct substitute. Minor dimensional variations within standard manufacturing tolerances do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both the CSRN2512FT50L0 and CSR2512FK50L0 are active production parts manufactured by Stackpole Electronics Inc with ROHS3 compliance and AEC-Q200 qualification (primary part). Selection between these parts should be based on inventory availability and supply chain requirements. The CSR2512FK50L0 offers higher stock levels at 2431 units compared to 1108 units for the CSRN2512FT50L0. Both parts satisfy identical electrical and mechanical specifications for current sense applications in automotive environments.

Frequently Asked Questions (FAQ)

Q: Can CSR2512FK50L0 be used as a direct replacement for CSRN2512FT50L0?

A: Yes. Both parts share identical resistance, tolerance, power rating, package type, temperature coefficient, and operating temperature range. The parts are mechanically and electrically interchangeable.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist within standard manufacturing tolerances. CSRN2512FT50L0 measures 0.250" L x 0.124" W with 0.028" maximum seated height. CSR2512FK50L0 measures 0.252" L x 0.126" W with 0.026" maximum seated height. These variations are within acceptable PCB layout tolerances for 2512 package footprints.

Q: Do both parts meet automotive qualification requirements?

A: The CSRN2512FT50L0 carries AEC-Q200 qualification. The CSR2512FK50L0 specification does not explicitly list AEC-Q200 in the provided data. Verify AEC-Q200 status with the manufacturer if automotive qualification is a design requirement.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are both parts RoHS compliant?

A: Yes. Both CSRN2512FT50L0 and CSR2512FK50L0 are ROHS3 compliant.
