Key Parameters

Substitute Part Grouping Explanation

The Ohmite 93J47RE qualifies as a parametric equivalent to the 93J47R based on the following criteria:

• Identical resistance value: 47 Ohms
• Identical tolerance: ±5%
• Identical power rating: 3.25W
• Identical composition: Wirewound
• Identical package type: Axial
• Identical temperature coefficient: ±30ppm/°C
• Identical features: Flame Retardant Coating, Safety
• Identical number of terminations: 2
• Equivalent physical dimensions: 0.233" Dia x 0.579" L (5.90mm x 14.70mm)

The primary difference between these parts is packaging format (Box versus Bulk) and RoHS compliance status. Both parts maintain full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Selection between the 93J47R and 93J47RE should be based on the following criteria:

93J47R (Box Packaging): Select this part when RoHS non-compliant components are acceptable for the application and box packaging is preferred for inventory management or distribution requirements.

93J47RE (Bulk Packaging): Select this part when ROHS3 compliance is mandated by design specifications, regulatory requirements, or customer standards. The bulk packaging format is suitable for high-volume manufacturing environments. Both parts are Active status with current inventory availability.

The electrical and mechanical performance of both parts is identical, ensuring direct interchangeability in circuit applications without performance degradation.

Frequently Asked Questions (FAQ)

Q: Are the 93J47R and 93J47RE electrically identical? A: Yes. Both parts have identical resistance (47 Ohms), tolerance (±5%), power rating (3.25W), temperature coefficient (±30ppm/°C), and composition (Wirewound). They are fully interchangeable from an electrical standpoint.

Q: What is the difference between these two parts? A: The primary differences are packaging format (Box versus Bulk) and RoHS compliance status (non-compliant versus ROHS3 compliant). Physical dimensions are equivalent within tolerance.

Q: Can I substitute 93J47RE for 93J47R in my design? A: Yes, provided your application does not have specific packaging requirements. The 93J47RE offers the additional benefit of ROHS3 compliance if that is a design requirement.

Q: Can I substitute 93J47R for 93J47RE? A: Substitution is possible only if RoHS non-compliance is acceptable for your application. Verify compliance requirements before making this substitution.

Q: Are the physical dimensions identical? A: The dimensions are equivalent. The 93J47R is 0.232" Dia x 0.579" L, and the 93J47RE is 0.233" Dia x 0.579" L. These minor variations fall within standard manufacturing tolerances for axial wirewound resistors and do not affect PCB layout or mechanical fit.

Q: What does the Series 90 designation indicate? A: Series 90 is the Ohmite product line classification for these wirewound resistors. Both substitute parts belong to the same series, confirming their design compatibility.

Q: Are both parts currently available? A: Yes. The 93J47R has 848 Pcs in stock, and the 93J47RE has 849 Pcs in stock, both listed as New Original inventory.
