Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Ohmite 33J100 is determined by strict equivalence across the following parameters:

• Resistance value: 100 Ohms
• Tolerance: ±5%
• Power rating: 3W
• Composition: Wirewound
• Package configuration: Axial
• Physical dimensions: 0.217" Dia x 0.594" L (5.50mm x 15.10mm)
• Termination count: 2

The substitute part 33J100E meets all these criteria. Variations in packaging format (Bulk versus standard packaging) and RoHS compliance status do not affect electrical or mechanical interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 33J100 and 33J100E are Active status components suitable for direct substitution in circuit designs requiring a 100 Ohm, 3W axial wirewound resistor. Selection between these parts should be based on compliance requirements and packaging needs:

The 33J100E offers ROHS3 compliance, making it the appropriate choice for applications subject to RoHS regulations. The 33J100 remains suitable for applications where RoHS compliance is not mandated. Both parts share identical electrical and mechanical specifications, ensuring functional equivalence in all circuit applications. Packaging format differences (Bulk for 33J100E versus standard for 33J100) affect procurement and handling but do not impact circuit performance.

Frequently Asked Questions (FAQ)

Q: Can the 33J100E replace the 33J100 in existing designs?

A: Yes. The 33J100E is electrically and mechanically equivalent to the 33J100. Both components have identical resistance (100 Ohms), tolerance (±5%), power rating (3W), composition (Wirewound), package type (Axial), and physical dimensions (0.217" Dia x 0.594" L). Direct substitution is valid for all circuit applications.

Q: What is the difference between the 33J100 and 33J100E?

A: The primary differences are packaging format and RoHS compliance status. The 33J100E is supplied in Bulk packaging and is ROHS3 compliant, while the 33J100 uses standard packaging and is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Which part should I select for RoHS-regulated applications?

A: The 33J100E is ROHS3 compliant and is the appropriate selection for applications subject to RoHS directives. The 33J100 is not RoHS compliant and should not be used in regulated environments.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both the 33J100 and 33J100E have identical dimensions of 0.217" Dia x 0.594" L (5.50mm x 15.10mm), ensuring compatibility with existing PCB layouts and mechanical assemblies.

Q: Can I use these parts interchangeably in my circuit?

A: Yes, provided compliance requirements are met. If RoHS compliance is not required, either part is suitable. If RoHS compliance is mandated, use the 33J100E exclusively.
