Substitute Part Grouping Explanation

The CSRN2010FKR500 qualifies as a direct substitute based on the following criteria:

Matching Parameters:

• Resistance value: 500 mOhms (identical)
• Power rating: 1W (identical)
• Package / Case: 2010 (5025 Metric) (identical)
• Composition: Thick Film (identical)
• Temperature coefficient: ±250ppm/°C (identical)
• Operating temperature range: -55°C ~ 155°C (identical)
• Current sense feature (identical)
• RoHS3 compliance (identical)
• MSL rating: 1 (Unlimited) (identical)

Tolerance Upgrade: The substitute part features ±1% tolerance compared to the main part's ±5% tolerance. This represents an improvement in precision while maintaining all other electrical and mechanical specifications. The tighter tolerance does not restrict application compatibility; it expands the range of applications where this component can be used.

Parameter Comparison

Engineering Selection Recommendations

Both CSRN2010JTR500 and CSRN2010FKR500 are active production parts with identical regulatory compliance profiles. Both achieve ROHS3 compliance, REACH unaffected status, and EAR99 export classification. The substitute part CSRN2010FKR500 provides improved tolerance specification (±1% versus ±5%) while maintaining all other electrical characteristics, mechanical dimensions, and environmental ratings. Selection between these parts depends on application tolerance requirements and design specifications rather than compliance or availability constraints.

Frequently Asked Questions (FAQ)

Q: Can CSRN2010FKR500 replace CSRN2010JTR500 in existing designs?

A: Yes. The substitute part maintains identical resistance value, power rating, package dimensions, and operating temperature range. The improved tolerance specification does not create compatibility issues with existing circuit designs.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use the 2010 (5025 Metric) package with identical length (0.197" / 5.00mm), width (0.097" / 2.45mm), and maximum seated height (0.030" / 0.75mm). PCB footprints and assembly processes remain unchanged.

Q: What is the significance of the tolerance difference?

A: CSRN2010JTR500 carries ±5% tolerance, while CSRN2010FKR500 carries ±1% tolerance. The tighter tolerance of the substitute part provides greater precision in current sensing applications where resistance accuracy is critical.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, carry MSL rating 1 (unlimited moisture sensitivity), and share identical operating temperature range (-55°C to 155°C) and temperature coefficient (±250ppm/°C).

Q: Are there inventory or lead time considerations between these parts?

A: Inventory levels differ between parts. Specific availability should be confirmed with the supplier for current project requirements.
