Key Parameters

Substitute Part Grouping Explanation

The RCWE2010R620FKEA qualifies as a direct substitute based on the following alignment of critical parameters:

Electrical specifications match exactly: 620 mOhms resistance, ±1% tolerance, and 1W power rating ensure functional equivalence in current sensing circuits. Both parts utilize thick film composition and maintain identical package designation (2010/5025 Metric).

Environmental compatibility is confirmed through matching operating temperature range (-55°C ~ 155°C) and RoHS3 compliance status. The substitute part achieves superior temperature coefficient performance (±100ppm/°C versus ±250ppm/°C), providing enhanced stability without compromising substitution eligibility.

Mechanical dimensions remain within acceptable variation: length 5.00mm (both parts), width 2.45mm to 2.50mm differential, and height 0.75mm to 0.70mm differential. These minor dimensional variations do not affect PCB footprint compatibility or assembly processes for 2010 package specifications.

The substitute part carries AEC-Q200 automotive qualification and moisture-resistant features, representing an upgrade path for applications requiring enhanced reliability without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain Active product status and ROHS3 compliance, confirming ongoing manufacturing support and regulatory alignment. The CSRN2010FTR620 serves as the primary specification reference for existing designs.

The RCWE2010R620FKEA represents a qualified upgrade option. Selection of the Vishay Dale substitute is appropriate when:

Automotive-grade reliability is required, as evidenced by AEC-Q200 certification on the substitute part. Enhanced temperature coefficient performance (±100ppm/°C) provides superior measurement accuracy in precision current sensing applications compared to the original specification (±250ppm/°C). Moisture-resistant features on the substitute part offer additional environmental protection without requiring circuit modifications.

Direct substitution is electrically and mechanically valid for standard industrial applications where automotive qualification is not mandated. Component selection should align with application requirements and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can RCWE2010R620FKEA replace CSRN2010FTR620 in existing designs without PCB modification?

A: Yes. Both parts share identical 2010 (5025 Metric) package designation and footprint specifications. Minor dimensional variations (width 2.45mm to 2.50mm, height 0.75mm to 0.70mm) fall within standard PCB design tolerances for this package class and do not require layout changes.

Q: What is the significance of the temperature coefficient difference between these parts?

A: The substitute part (±100ppm/°C) exhibits superior temperature stability compared to the original (±250ppm/°C). This means the resistance value changes less with temperature fluctuations, resulting in more stable current measurement accuracy across the -55°C to 155°C operating range. This represents a performance improvement, not a limitation.

Q: Are both parts suitable for current sensing applications?

A: Yes. Both parts are specified as current sense thick film resistors with matching 620 mOhms resistance and ±1% tolerance. The electrical characteristics required for precision current measurement are identical between the two parts.

Q: What does AEC-Q200 certification on the substitute part indicate?

A: AEC-Q200 is an automotive industry standard qualification demonstrating the part meets stringent reliability, temperature cycling, and environmental stress testing requirements. This certification is relevant for automotive and high-reliability applications but does not affect substitution validity for general industrial use.

Q: Are there any moisture sensitivity concerns with either part?

A: No. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity limitations. Standard handling and storage practices apply without special moisture control requirements.

Q: Can the substitute part be used in high-temperature applications near 155°C?

A: Yes. Both parts are rated for continuous operation to 155°C. The superior temperature coefficient of the substitute part (±100ppm/°C) provides enhanced measurement stability at elevated temperatures compared to the original specification.
