Substitute Part Grouping Explanation

The CSRN2010FK25L0 qualifies as a direct substitute based on the following criteria:

Electrical equivalence is maintained across all critical parameters: resistance value (25 mOhms), power rating (1W), temperature coefficient (±250ppm/°C), and operating temperature range (-55°C ~ 155°C). The package specification remains identical at 2010 (5025 Metric) with matching physical dimensions and termination count.

The primary distinction is tolerance specification. The substitute part CSRN2010FK25L0 provides ±1% tolerance compared to the ±5% tolerance of the main part. This represents an upgrade in precision capability while maintaining full mechanical and thermal compatibility. Both parts share identical composition (Thick Film), features (Current Sense), and compliance certifications (ROHS3, REACH Unaffected).

Parameter Comparison

Engineering Selection Recommendations

Both CSRN2010JK25L0 and CSRN2010FK25L0 maintain Active product status with full ROHS3 compliance and REACH Unaffected certification. Selection between these parts depends on tolerance requirements for the application circuit. The CSRN2010JK25L0 with ±5% tolerance is suitable for applications where standard precision current sensing is acceptable. The CSRN2010FK25L0 with ±1% tolerance provides enhanced accuracy for precision measurement circuits requiring tighter tolerance control. Both parts are mechanically and thermally interchangeable within the specified operating range.

Frequently Asked Questions (FAQ)

Q: Can CSRN2010FK25L0 replace CSRN2010JK25L0 in existing designs?

A: Yes. The CSRN2010FK25L0 is mechanically and electrically compatible. It occupies the same 2010 (5025 Metric) package footprint with identical dimensions and termination configuration. The ±1% tolerance of the substitute part is tighter than the ±5% specification of the original part, making it a direct upgrade without circuit modification.

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

A: The tolerance specification differs. CSRN2010JK25L0 provides ±5% tolerance while CSRN2010FK25L0 provides ±1% tolerance. All other electrical parameters including resistance value, power rating, temperature coefficient, and operating temperature range are identical.

Q: Are there any thermal or environmental differences?

A: No. Both parts operate across -55°C to 155°C with identical ±250ppm/°C temperature coefficient. Moisture sensitivity level is 1 (Unlimited) for both parts, indicating no special handling requirements.

Q: Do these parts have different compliance certifications?

A: No. Both CSRN2010JK25L0 and CSRN2010FK25L0 are ROHS3 Compliant and REACH Unaffected with identical regulatory status.

Q: Which part should be selected for new designs?

A: Selection depends on circuit tolerance requirements. For applications requiring standard precision, either part is acceptable. For circuits requiring tighter tolerance control, CSRN2010FK25L0 with ±1% tolerance is the appropriate choice.
