Substitute Part Grouping Explanation

Substitute parts for the RW2R0DAR020J are qualified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

• Resistance value: 20 mOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 2W (exact match required)
• Composition: Wirewound (exact match required)
• Package / Case: 4524 J-Lead (exact match required)
• Supplier Device Package: SMD J-Lead, Recessed (exact match required)
• Operating temperature range: -55°C ~ 150°C (exact match required)
• Number of terminations: 2 (exact match required)
• Application feature: Current Sense (exact match required)

The RW2R0DAR020JE qualifies as a direct substitute, meeting all electrical and mechanical specifications while differing only in packaging format and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The RW2R0DAR020JE serves as a direct electrical and mechanical equivalent to the RW2R0DAR020J. Both parts are manufactured by Ohmite and maintain identical specifications for resistance, tolerance, power rating, composition, package type, and operating temperature range.

The primary distinction between these parts is compliance certification. The RW2R0DAR020JE carries ROHS3 compliance and REACH Unaffected status, whereas the RW2R0DAR020J is RoHS non-compliant. Selection between these parts should be based on regulatory requirements applicable to the end application and target markets.

Both parts maintain MSL 1 (Unlimited) moisture sensitivity classification and identical ECCN and HTSUS codes, indicating equivalent handling and regulatory treatment for export purposes.

Frequently Asked Questions (FAQ)

Q: Can RW2R0DAR020JE be used as a direct replacement for RW2R0DAR020J?

A: Yes. The RW2R0DAR020JE meets all electrical and mechanical specifications of the RW2R0DAR020J, including resistance value, tolerance, power rating, package type, and operating temperature range. Substitution is valid from a functional standpoint.

Q: What is the difference between these two parts?

A: The RW2R0DAR020JE is ROHS3 compliant and REACH Unaffected, while the RW2R0DAR020J is RoHS non-compliant. Electrical and mechanical specifications are identical. Packaging format differs (Bulk for RW2R0DAR020JE versus standard for RW2R0DAR020J).

Q: Are there any package or dimensional differences?
