Key Parameters

Substitute Part Grouping Explanation

The RW2R0DAR050FE qualifies as a direct substitute for the RW2R0DAR050F based on identical electrical and mechanical parameters. Substitution eligibility is determined by the following criteria:

• Resistance value: 50 mOhms
• Tolerance specification: ±1%
• Power rating: 2W
• Package type: 4524 J-Lead
• Operating temperature range: -55°C to 150°C
• Termination count: 2
• Composition: Wirewound
• Application feature: Current Sense

The RW2R0DAR050FE maintains all critical electrical characteristics and physical dimensions required for direct replacement. The primary distinction lies in packaging format (Bulk versus standard packaging) and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RW2R0DAR050F and RW2R0DAR050FE are electrically and mechanically interchangeable for current sense applications requiring 50 mOhm ±1% 2W wirewound resistors in 4524 J-Lead packages.

The RW2R0DAR050FE offers ROHS3 compliance, making it the preferred selection for applications subject to RoHS3 regulatory requirements. The RW2R0DAR050F remains suitable for applications where RoHS compliance is not mandated. Both parts maintain identical electrical performance, thermal characteristics, and physical dimensions.

Selection between these parts should be based on compliance requirements and packaging format preferences. The RW2R0DAR050FE is available in Bulk packaging, while the RW2R0DAR050F uses standard packaging. Both maintain Active product status with adequate inventory availability.

Frequently Asked Questions (FAQ)

Q: Can RW2R0DAR050FE replace RW2R0DAR050F in existing designs?

A: Yes. The RW2R0DAR050FE is a direct substitute. Both parts share identical resistance values (50 mOhms), tolerance (±1%), power rating (2W), package type (4524 J-Lead), operating temperature range (-55°C to 150°C), and physical dimensions. No circuit modifications are required.

Q: What is the primary difference between these two part numbers?

A: The RW2R0DAR050FE is ROHS3 compliant, while the RW2R0DAR050F is RoHS non-compliant. Packaging format also differs: RW2R0DAR050FE uses Bulk packaging. Electrical and mechanical specifications are identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.455" L x 0.240" W (11.56mm x 6.10mm) with a maximum seated height of 0.231" (5.87mm). Both use SMD J-Lead, Recessed termination style and are housed in 4524 J-Lead packages.

Q: Which part should be selected for RoHS-compliant applications?

A: The RW2R0DAR050FE is ROHS3 compliant and is the appropriate selection for applications requiring RoHS compliance. The RW2R0DAR050F is non-compliant and should not be used in RoHS-regulated environments.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both the RW2R0DAR050F and RW2R0DAR050FE carry Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.

Q: Are there inventory differences between these parts?

A: Yes. The RW2R0DAR050F has 678 units in stock, while the RW2R0DAR050FE has 946 units available. Both maintain adequate inventory for production requirements.
