Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSRN2010FTR910 is determined by strict alignment of the following parameters:

• Resistance value: 910 mOhms
• Tolerance: ±1%
• Power rating: 1W
• Package type: 2010 (5025 Metric)
• Composition: Thick Film
• Operating temperature range: -55°C ~ 155°C minimum
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1 or better

The RCWE2010R910FKEA from Vishay Dale meets all substitution criteria. This part maintains identical electrical specifications and package dimensions while offering enhanced features including AEC-Q200 automotive qualification and moisture-resistant construction.

Parameter Comparison

Engineering Selection Recommendations

Both the CSRN2010FTR910 and RCWE2010R910FKEA are Active status components with ROHS3 compliance and identical core electrical specifications. The RCWE2010R910FKEA offers improved temperature coefficient performance (±100ppm/°C versus ±250ppm/°C) and includes AEC-Q200 automotive qualification with moisture-resistant construction. Dimensional compatibility is maintained across both parts with negligible height variation (0.75mm versus 0.70mm). Selection between these parts depends on application requirements for automotive qualification and temperature stability performance.

Frequently Asked Questions (FAQ)

Q: Can RCWE2010R910FKEA replace CSRN2010FTR910 in existing designs?

A: Yes. Both parts share identical resistance (910 mOhms), tolerance (±1%), power rating (1W), package type (2010), and operating temperature range (-55°C ~ 155°C). Dimensional compatibility is confirmed with maximum height variation of 0.05mm.

Q: What is the significance of the temperature coefficient difference?

A: The RCWE2010R910FKEA exhibits ±100ppm/°C versus ±250ppm/°C for the CSRN2010FTR910. This represents improved temperature stability in the Vishay Dale part, resulting in more predictable resistance variation across the operating temperature range.

Q: Does AEC-Q200 qualification affect substitution eligibility?

A: AEC-Q200 is an additional qualification present on the RCWE2010R910FKEA. This automotive standard does not restrict substitution but indicates enhanced reliability testing and qualification for automotive applications.

Q: Are there packaging differences between these parts?

A: Both parts are supplied in Tape & Reel (TR) packaging. Dimensional differences are minimal: width tolerance of 0.05mm (2.45mm versus 2.50mm) and height difference of 0.05mm (0.75mm versus 0.70mm). These variations remain within standard PCB assembly tolerances.

Q: What does MSL 1 (Unlimited) mean for storage and handling?

A: MSL 1 indicates unlimited shelf life without moisture baking requirements. Both parts can be stored at standard conditions without time-based moisture sensitivity constraints.
