Key Parameters

Substitute Part Grouping Explanation

The 93J8R2E qualifies as a parametric equivalent based on the following criteria:

Electrical Parameters (Identical):

• Resistance: 8.2 Ohms
• Tolerance: ±5%
• Power Rating: 3.25W
• Temperature Coefficient: ±100ppm/°C
• Composition: Wirewound

Mechanical Parameters (Identical):

• Package Type: Axial
• Size/Dimension: 0.233" Dia x 0.579" L (5.90mm x 14.70mm)
• Number of Terminations: 2
• Series: 90

Differentiation: The primary distinction between the main part and substitute is packaging format: 93J8R2 is supplied in Box packaging, while 93J8R2E is supplied in Bulk packaging. Additionally, 93J8R2E carries ROHS3 compliance certification, whereas the main part is RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

93J8R2 (Box Packaging): Select this part number when box packaging is required for inventory management, component traceability, or specific procurement workflows. This configuration is suitable for applications without RoHS3 compliance mandates.

93J8R2E (Bulk Packaging): Select this part number when bulk packaging is acceptable and ROHS3 compliance is required. This variant is appropriate for high-volume production environments and applications subject to RoHS3 regulatory requirements. The negligible dimensional variance (0.001" difference in diameter) does not affect circuit board layout or mechanical fit.

Both parts are active products from Ohmite's Series 90 line and are electrically and mechanically interchangeable within the specified parameters.

Frequently Asked Questions (FAQ)

Q: Are 93J8R2 and 93J8R2E electrically identical? A: Yes. Both parts have identical resistance (8.2 Ohms), tolerance (±5%), power rating (3.25W), temperature coefficient (±100ppm/°C), and composition (wirewound). They are direct electrical equivalents.

Q: What is the difference between Box and Bulk packaging? A: Box packaging typically provides individual component packaging with documentation and traceability labels, suitable for smaller orders and component tracking. Bulk packaging supplies components in larger quantities without individual packaging, reducing material waste and cost for high-volume applications.

Q: Can I use 93J8R2E as a direct replacement for 93J8R2 on a circuit board? A: Yes. The dimensional difference (0.001" in diameter) is negligible and does not affect PCB layout, hole sizing, or mechanical fit. Both parts use identical axial termination and are mechanically interchangeable.

Q: Does RoHS3 compliance matter for my application? A: RoHS3 compliance is required if your application or end-market is subject to European Union Restriction of Hazardous Substances regulations. If RoHS3 compliance is mandatory, use 93J8R2E. If not required, either part is acceptable.

Q: Are there any performance differences between the two part numbers? A: No. Both parts have identical electrical performance characteristics, including temperature coefficient, power dissipation capability, and tolerance specifications. Performance is equivalent across all operating conditions within the specified temperature range.
