Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RW2R0DAR005J 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 with SMD J-Lead recessed termination
• Physical dimensions: 0.455" L x 0.240" W (11.56mm x 6.10mm)
• Height seated maximum: 0.231" (5.87mm)
• Operating temperature range: -55°C ~ 150°C
• Number of terminations: 2
• Moisture sensitivity level: 1 (Unlimited)

The RW2R0DAR005JE qualifies as a direct substitute based on complete alignment with all electrical and mechanical parameters. Packaging configuration differences (Bulk versus standard packaging) do not affect functional equivalence or circuit performance.

Parameter Comparison

Engineering Selection Recommendations

The RW2R0DAR005JE serves as a direct functional equivalent to the RW2R0DAR005J. Both components are manufactured by Ohmite and maintain active product status with identical electrical specifications and mechanical dimensions.

A key distinction exists in regulatory compliance: the RW2R0DAR005JE achieves ROHS3 compliance, while the RW2R0DAR005J is RoHS non-compliant. For applications subject to RoHS directives or procurement policies requiring RoHS compliance, the RW2R0DAR005JE is the appropriate selection. The RW2R0DAR005JE also carries REACH Unaffected status, providing additional regulatory clarity for European market applications.

Both parts share identical electrical performance characteristics, package geometry, and thermal operating range. Selection between these parts should be based on regulatory requirements and supply chain availability rather than technical performance considerations.

Frequently Asked Questions (FAQ)

Q: Can the RW2R0DAR005JE replace the RW2R0DAR005J in existing designs?

A: Yes. The RW2R0DAR005JE is electrically and mechanically equivalent. Both components feature identical resistance values, tolerance, power ratings, package dimensions, and operating temperature ranges. Direct substitution is possible without circuit redesign.

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

A: The primary differences are packaging configuration (Bulk versus standard) and regulatory compliance status. The RW2R0DAR005JE is ROHS3 compliant and REACH Unaffected, while the RW2R0DAR005J is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns with the 4524 J-Lead package?

A: No. Both parts use the identical 4524 J-Lead SMD package with recessed termination. Physical dimensions, height, and termination count are identical, ensuring PCB layout and assembly compatibility.

Q: Which part should I select for new designs?

A: For new designs, the RW2R0DAR005JE is recommended due to its ROHS3 compliance status, which aligns with current regulatory standards and future-proofs the design against evolving compliance requirements.

Q: Do these parts have different thermal or electrical performance?

A: No. Both components maintain identical operating temperature ranges (-55°C ~ 150°C), power ratings (2W), and resistance specifications (5 mOhms ±5%). Thermal and electrical performance are equivalent.
