Key Parameters

Substitute Part Grouping Explanation

Substitution for the CSRF2010FK5L00 is determined by strict equivalence across the following critical parameters:

• Resistance value: 5 mOhms
• Tolerance: ±1%
• Power rating: 1W
• Package type: 2010 (5025 Metric)
• Composition: Metal Foil
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 125°C
• Features: Current Sense, Moisture Resistant

The CSRF2010FT5L00 meets all these criteria and is classified as a direct substitute. The primary distinction between these parts is packaging format: the main part uses standard packaging while the substitute is supplied in Tape & Reel (TR) format. This difference does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The CSRF2010FT5L00 is a direct electrical and mechanical equivalent to the CSRF2010FK5L00. Both parts maintain identical electrical specifications, physical dimensions, and compliance certifications. The CSRF2010FT5L00 is currently in active production status, whereas the original part is obsolete.

Selection between these parts should be based on procurement and assembly requirements. The CSRF2010FT5L00 in Tape & Reel format is suitable for automated pick-and-place assembly operations. Both parts satisfy ROHS3 compliance and REACH requirements, ensuring regulatory compatibility in current manufacturing environments.

Frequently Asked Questions (FAQ)

Q: Can CSRF2010FT5L00 be used as a direct replacement for CSRF2010FK5L00?

A: Yes. Both parts are electrically and mechanically identical. They share the same resistance value (5 mOhms), tolerance (±1%), power rating (1W), package dimensions (2010/5025 Metric), and operating specifications. The only difference is packaging format.

Q: What is the difference between the standard packaging and Tape & Reel format?

A: Tape & Reel (TR) packaging is designed for automated assembly processes using pick-and-place equipment. Standard packaging is typically used for manual assembly or smaller volume applications. The electrical and mechanical properties of the component remain unchanged.

Q: Are there any compliance or certification differences between these parts?

A: No. Both CSRF2010FK5L00 and CSRF2010FT5L00 carry identical RoHS3 compliance, REACH unaffected status, and Moisture Sensitivity Level 1 (Unlimited) ratings.

Q: Why is the original part listed as obsolete?

A: Product obsolescence is determined by the manufacturer based on market demand and production decisions. The CSRF2010FT5L00 remains in active production and provides full functional equivalence.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.197" L x 0.098" W (5.00mm x 2.50mm) with a maximum seated height of 0.037" (0.95mm). They are pin-compatible and footprint-compatible.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes, provided the assembly process accommodates the packaging format. If the design uses automated assembly with tape-fed components, the CSRF2010FT5L00 is the appropriate choice. Both parts are electrically and mechanically interchangeable at the component level.
