CSRN2010FK1R00 Equivalent & Substitute Parts

Part Overview

The CSRN2010FK1R00 is a 1 Ohm ±1% 1W chip resistor in 2010 (5025 Metric) package manufactured by Stackpole Electronics Inc. This current sense thick film resistor is designed for precision applications requiring low resistance values with tight tolerance specifications. The part is active in production with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified to provide design flexibility, inventory alternatives, and supply chain continuity while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution for the CSRN2010FK1R00 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part CSRN2010FT1R00 qualifies as a direct equivalent based on the following criteria:

• Identical resistance value: 1 Ohms
• Identical tolerance: ±1%
• Identical power rating: 1W
• Identical package: 2010 (5025 Metric)
• Identical composition: Thick Film
• Identical current sense feature designation
• Identical temperature coefficient: ±250ppm/°C
• Identical operating temperature range: -55°C ~ 155°C
• Identical physical dimensions and height specifications
• Identical RoHS3 compliance status
• Identical MSL rating: 1 (Unlimited)

The only difference between these parts is the packaging designation (FK vs FT), which refers to different tape and reel configurations from the same manufacturer. Both are supplied in Tape & Reel (TR) format and are functionally and mechanically interchangeable.

Parameter Comparison

Engineering Selection Recommendations

Both CSRN2010FK1R00 and CSRN2010FT1R00 are active production parts from Stackpole Electronics Inc with full ROHS3 compliance and identical electrical performance specifications. Selection between these parts is based on packaging tape and reel configuration availability and inventory status rather than functional differences. Both parts meet the same regulatory requirements (ROHS3 Compliant, REACH Unaffected, EAR99 classification) and carry identical reliability ratings for current sense applications. The choice between FK and FT designations should be determined by your assembly equipment compatibility and procurement lead times.

Frequently Asked Questions (FAQ)

Q: Are CSRN2010FK1R00 and CSRN2010FT1R00 electrically identical?

A: Yes. Both parts have identical electrical specifications: 1 Ohm resistance, ±1% tolerance, 1W power rating, ±250ppm/°C temperature coefficient, and -55°C to 155°C operating range.

Q: What is the difference between FK and FT packaging designations?

A: FK and FT refer to different tape and reel configurations for the same 2010 (5025 Metric) package. Both are supplied in Tape & Reel (TR) format. The difference relates to reel specifications and assembly equipment compatibility, not component performance.

Q: Can I use CSRN2010FT1R00 as a direct replacement for CSRN2010FK1R00 on my PCB?

A: Yes. The parts are mechanically and electrically interchangeable. Both have identical dimensions (0.197" L x 0.097" W, 5.00mm x 2.45mm), height (0.030" max), and termination specifications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both CSRN2010FK1R00 and CSRN2010FT1R00 are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes.

Q: Which part should I specify for new designs?

A: Either part is suitable for new designs. Selection should be based on your assembly equipment's tape and reel compatibility and current inventory availability from your supplier.
