Substitute Part Grouping Explanation

Substitution for the Ohmite 33J15R is determined by strict equivalence across the following critical parameters:

• Resistance value: 15 Ohms
• Tolerance: ±5%
• Power rating: 3W
• Composition: Wirewound
• Package / Case: Axial
• Physical dimensions: 0.217" Dia x 0.594" L (5.50mm x 15.10mm)
• Number of terminations: 2
• Series classification: High Energy Wirewound

The substitute part 33J15RE meets all electrical and mechanical requirements for direct substitution. Differences in packaging format (Bulk vs. standard) and compliance certifications do not affect functional compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 33J15R and 33J15RE are Active status components suitable for direct substitution in axial wirewound resistor applications. Selection between these parts should be based on the following criteria:

• 33J15R: Select when RoHS non-compliant components are acceptable for the application and standard packaging is required.
• 33J15RE: Select when RoHS compliance is mandated by design specifications or regulatory requirements. This part offers identical electrical and mechanical performance with enhanced environmental compliance certification.

Both parts carry the same ECCN classification (EAR99) and are suitable for general commercial applications.

Frequently Asked Questions (FAQ)

Q: Can the 33J15RE be used as a direct replacement for the 33J15R in existing designs?

A: Yes. The 33J15RE is electrically and mechanically equivalent to the 33J15R. Both components share identical resistance (15 Ohms), tolerance (±5%), power rating (3W), composition (Wirewound), package type (Axial), and physical dimensions (0.217" Dia x 0.594" L). No circuit modifications are required.

Q: What is the primary difference between these two parts?

A: The primary difference is RoHS compliance status. The 33J15RE is RoHS Compliant, while the 33J15R is RoHS non-compliant. Electrically and mechanically, both parts are identical.

Q: Are there any packaging differences that affect installation?

A: The 33J15RE is supplied in Bulk packaging, while the 33J15R uses standard packaging. Both parts maintain identical physical dimensions and axial lead configuration, ensuring compatibility with standard through-hole PCB layouts and assembly processes.

Q: Which part should be selected for new designs?

A: Selection depends on compliance requirements. For designs requiring RoHS compliance, specify the 33J15RE. For applications without RoHS mandates, either part is acceptable based on availability and procurement preferences.

Q: Are both parts currently in stock?

A: Yes. The 33J15R has 1066 Pcs available, and the 33J15RE has 934 Pcs available as new original inventory.
