Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Ohmite 20JR33 is determined by the following critical parameters:

• Resistance Value: 330 mOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Power Rating: 10W (exact match required)
• Composition: Wirewound (exact match required)
• Package Type: Axial (exact match required)
• Physical Dimensions: 0.394" Dia x 1.858" L / 10.00mm x 47.20mm (exact match required)
• Features: Flame Retardant Coating, Safety (exact match required)

The substitute part 20JR33E meets all electrical and mechanical parameters specified above. The primary distinction between the main part and its substitute is the packaging format and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 20JR33 and 20JR33E are functionally equivalent for circuit applications requiring a 330 mOhms ±5% 10W axial wirewound resistor. Selection between these parts should be based on the following criteria:

20JR33: Select this part number when standard packaging is required and RoHS non-compliant components are acceptable for your application.

20JR33E: Select this part number when ROHS3 compliance is mandated by design specifications, regulatory requirements, or procurement policies. This variant is supplied in bulk packaging format.

Both parts share identical electrical characteristics, physical dimensions, and safety features. The choice between them is determined by compliance requirements and packaging preferences rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Are the 20JR33 and 20JR33E electrically interchangeable?

A: Yes. Both parts have identical resistance values (330 mOhms), tolerance (±5%), power rating (10W), composition (wirewound), and physical dimensions (0.394" Dia x 1.858" L). They are direct electrical equivalents.

Q: What is the difference between 20JR33 and 20JR33E?

A: The primary differences are packaging format (standard vs. bulk) and RoHS compliance status. The 20JR33 is RoHS non-compliant, while the 20JR33E is ROHS3 compliant. All electrical and mechanical specifications are identical.

Q: Can I use 20JR33E as a direct replacement for 20JR33 in my circuit board design?

A: Yes. The parts are mechanically and electrically identical. No circuit modifications or PCB layout changes are required. The substitution is valid for both new designs and existing assemblies.

Q: Does RoHS compliance affect the performance of the resistor?

A: No. RoHS compliance status reflects the materials and manufacturing process used but does not alter the electrical performance, power rating, or reliability characteristics of the component.

Q: Are there any packaging considerations when switching between these part numbers?

A: The 20JR33E is supplied in bulk packaging, while the 20JR33 uses standard packaging. Verify that your procurement and inventory management systems support the bulk format before ordering the 20JR33E.

Q: What is the temperature coefficient for these resistors?

A: Temperature coefficient data is not provided in the component specifications for either part number.
