Key Parameters

Substitute Part Grouping Explanation

The Ohmite 92J20RE qualifies as a parametric equivalent to the 92J20R based on the following criteria:

• Identical resistance value: 20 Ohms
• Matching tolerance: ±5%
• Identical power rating: 2.25W
• Same composition: Wirewound
• Identical package type: Axial
• Matching temperature coefficient: ±30ppm/°C
• Identical physical dimensions: 0.220" Dia x 0.406" L (5.60mm x 10.30mm)
• Same series designation: 90
• Identical features: Flame Retardant Coating, Safety

The primary difference between these parts is packaging format and RoHS compliance status. The 92J20RE is supplied in bulk packaging and meets ROHS3 compliance, whereas the 92J20R is non-compliant.

Parameter Comparison

Engineering Selection Recommendations

Both the 92J20R and 92J20RE are active production components from Ohmite's Series 90 wirewound resistor line. Selection between these parts should be based on regulatory and compliance requirements:

• Use 92J20R when RoHS non-compliant components are acceptable or required by legacy design specifications.
• Use 92J20RE when ROHS3 compliance is mandated by application requirements, environmental regulations, or customer specifications.

Both parts are electrically and mechanically interchangeable within the same circuit design. Packaging format (standard versus bulk) may influence procurement decisions based on order quantity and inventory management practices.

Frequently Asked Questions (FAQ)

Q: Are the 92J20R and 92J20RE electrically identical?

A: Yes. Both parts have identical resistance (20 Ohms), tolerance (±5%), power rating (2.25W), temperature coefficient (±30ppm/°C), and composition (wirewound). They are direct electrical equivalents.

Q: Can I substitute 92J20RE for 92J20R in an existing design?

A: Yes, provided your application permits ROHS3 compliant components. The physical dimensions, package type, and electrical characteristics are identical, ensuring direct mechanical and electrical compatibility.

Q: What is the difference between these two parts?

A: The primary differences are RoHS compliance status (92J20R is non-compliant; 92J20RE is ROHS3 compliant) and packaging format (92J20R is standard; 92J20RE is bulk). All electrical and mechanical specifications are identical.

Q: Which part should I use for new designs?

A: For new designs, 92J20RE is recommended due to ROHS3 compliance, which aligns with current environmental and regulatory standards. However, if legacy specifications require non-compliant components, 92J20R remains available.

Q: Are the physical dimensions the same?

A: Yes. Both parts have identical dimensions of 0.220" Dia x 0.406" L (5.60mm x 10.30mm) and use the same axial package type, ensuring identical PCB footprint and mounting compatibility.
