RW2S0DAR005J Equivalent & Substitute Parts

Part Overview

The RW2S0DAR005J is a 5 mOhms ±5% 2W wirewound chip resistor manufactured by Ohmite, designed for current sense applications. This component features a 4524 J-Lead package with SMD pedestal termination and operates across a temperature range of -55°C to 150°C. The part is currently in active production status with 903 units available in inventory. Substitute parts are identified to address packaging variations, compliance requirements, and supply chain flexibility while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RW2S0DAR005J is determined by strict equivalence across the following critical parameters:

• Resistance value: 5 mOhms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Wirewound
• Package type: 4524 J-Lead
• Operating temperature range: -55°C to 150°C
• Physical dimensions: 0.455" L x 0.240" W (11.56mm x 6.10mm)
• Termination count: 2

The identified substitute part RW2R0DAR005JE meets all electrical and mechanical requirements. The primary difference lies in the supplier device package configuration (SMD J-Lead Recessed versus Pedestal) and RoHS compliance status, which do not affect functional equivalence in current sense applications.

Parameter Comparison

Engineering Selection Recommendations

Both RW2S0DAR005J and RW2R0DAR005JE are active production components from Ohmite with identical electrical performance and mechanical compatibility. Selection between these parts should be based on the following criteria:

RW2S0DAR005J is suitable for applications where RoHS non-compliance is acceptable and pedestal termination geometry is required for specific PCB layout constraints.

RW2R0DAR005JE is the appropriate choice for applications requiring ROHS3 compliance and where recessed J-Lead termination is compatible with board design. This part also carries REACH Unaffected status.

Both components are functionally equivalent for current sense applications and maintain identical resistance, tolerance, power rating, and operating temperature specifications.

Frequently Asked Questions (FAQ)

Q: Can RW2R0DAR005JE be used as a direct replacement for RW2S0DAR005J?

A: Yes. Both parts are electrically and mechanically equivalent with identical resistance (5 mOhms ±5%), power rating (2W), package dimensions (4524 J-Lead, 11.56mm x 6.10mm), and operating temperature range (-55°C to 150°C). The primary difference is the J-Lead termination style (recessed versus pedestal) and RoHS compliance status.

Q: What is the difference between SMD J-Lead Pedestal and SMD J-Lead Recessed?

A: The termination style affects the component's seating profile on the PCB. Pedestal termination (RW2S0DAR005J) provides a raised mounting surface, while recessed termination (RW2R0DAR005JE) sits lower. Verify PCB layout compatibility before substitution.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS3 compliance in RW2R0DAR005JE does not alter electrical characteristics. Compliance status is a regulatory and material composition consideration, not a functional parameter.

Q: Are both parts suitable for current sense applications?

A: Yes. Both RW2S0DAR005J and RW2R0DAR005JE are designated for current sense applications with identical wirewound composition and low resistance specifications.

Q: What is the inventory status for these parts?

A: RW2S0DAR005J has 903 units in stock. RW2R0DAR005JE has 823 units in stock. Both are available as new original components.
