Substitute Part Grouping Explanation

Substitute parts for the 92J3R0 are identified based on strict parametric equivalence across the following critical criteria:

• Resistance value: 3 Ohms
• Tolerance: ±5%
• Power rating: 2.25W
• Composition: Wirewound
• Package: Axial through-hole
• Physical dimensions: 0.220" Dia x 0.406" L (5.60mm x 10.30mm)
• Temperature coefficient: ±100ppm/°C
• Features: Flame retardant coating and safety construction

The 92J3R0E is classified as a parametric equivalent substitute. It maintains all electrical and mechanical specifications identical to the main part while differing in packaging format (bulk versus standard) and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 92J3R0 and 92J3R0E are electrically and mechanically identical, with selection determined by compliance and packaging requirements:

• 92J3R0: Select when RoHS non-compliant components are acceptable for the application and standard packaging is required.
• 92J3R0E: Select when ROHS3 compliance is mandated or when bulk packaging is preferred. This variant offers higher inventory availability (1087 units versus 775 units) and REACH compliance certification.

Both parts are active products from Ohmite's Series 90 line and are suitable for direct substitution in through-hole circuit designs requiring 3 Ohm, 2.25W wirewound resistors with flame retardant construction.

Frequently Asked Questions (FAQ)

Q: Can the 92J3R0E replace the 92J3R0 in existing designs?

A: Yes. The 92J3R0E is a parametric equivalent with identical electrical and mechanical specifications. The only differences are packaging format (bulk versus standard) and compliance certifications. Direct substitution is valid for all through-hole applications.

Q: What is the difference between standard and bulk packaging?

A: Standard packaging refers to the manufacturer's default distribution format, while bulk packaging typically indicates larger quantity containers. Both contain the same component with identical specifications. Bulk packaging may be preferred for high-volume production or when inventory consolidation is beneficial.

Q: Does the RoHS compliance difference affect circuit performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both parts deliver identical 3 Ohm resistance, 2.25W power rating, and ±5% tolerance. Selection between RoHS-compliant and non-compliant variants depends on regulatory requirements for the end application.

Q: Are the physical dimensions identical between both parts?

A: Yes. Both the 92J3R0 and 92J3R0E measure 0.220" diameter by 0.406" length (5.60mm x 10.30mm) and are axial through-hole components. They are mechanically interchangeable on PCBs designed for this form factor.

Q: What does REACH Unaffected mean for the 92J3R0E?

A: REACH Unaffected indicates that the component is not subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) restrictions. This certification is relevant for applications in regulated markets, particularly in Europe.
