Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSR2010FK75L0 is determined by the following critical parameters:

• Resistance value: 75 mOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 1W (exact match required)
• Package: 2010 (5025 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Features: Current Sense (exact match required)
• Operating temperature range: -55°C ~ 155°C (minimum requirement)
• RoHS compliance: ROHS3 Compliant (required)

The CSRN2010FK75L0 meets all substitution criteria. Variations in temperature coefficient and physical dimensions within supplier tolerances do not affect functional equivalence for current sense applications.

Parameter Comparison

Engineering Selection Recommendations

Both CSR2010FK75L0 and CSRN2010FK75L0 are Active status components manufactured by Stackpole Electronics Inc and maintain ROHS3 compliance. Selection between these parts should be based on:

• Inventory availability and lead time requirements
• PCB layout constraints related to dimensional tolerances (width and height variations)
• Application sensitivity to temperature coefficient performance (±100ppm/°C vs ±250ppm/°C)
• Packaging format requirements (both supplied in Tape & Reel format)

Both parts satisfy the core electrical specifications for 75 mOhm, ±1%, 1W current sense applications within the -55°C to 155°C operating range.

Frequently Asked Questions (FAQ)

Q: Can CSRN2010FK75L0 be used as a direct replacement for CSR2010FK75L0?

A: Yes, within the constraints of your application's temperature coefficient tolerance. Both parts share identical resistance, tolerance, power rating, package type, and operating temperature range. The CSRN series has a higher temperature coefficient (±250ppm/°C vs ±100ppm/°C), which may affect accuracy in temperature-sensitive current measurement circuits.

Q: Are there physical compatibility concerns between these parts?

A: Minor dimensional variations exist. The CSRN2010FK75L0 is 0.003" narrower (2.45mm vs 2.54mm) and 0.004" taller (0.75mm vs 0.65mm) when seated. Verify PCB pad spacing and component clearance before substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both CSR2010FK75L0 and CSRN2010FK75L0 are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Q: What is the primary difference between these substitute parts?

A: The temperature coefficient specification differs. CSR2010FK75L0 specifies ±100ppm/°C, while CSRN2010FK75L0 specifies ±250ppm/°C. All other electrical and mechanical parameters remain equivalent.

Q: Are both parts available in the same packaging format?

A: Yes. Both parts are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.
