Parameter Comparison

Engineering Selection Recommendations

Both the 93J39R and 93J39RE are active production components from Ohmite with identical electrical and mechanical specifications. Selection between these parts should be based on the following criteria:

93J39R is appropriate for applications where RoHS non-compliant components are acceptable or required by design specifications.

93J39RE is the preferred choice for applications requiring ROHS3 compliance. This substitute part maintains full electrical and thermal equivalence while meeting current regulatory requirements for restricted substances.

Both parts are suitable for direct substitution in through-hole circuit board applications requiring 39 Ohm, 3.25W axial wirewound resistors with flame retardant coating.

Frequently Asked Questions (FAQ)

Q: Can the 93J39RE be used as a direct replacement for the 93J39R?

A: Yes. The 93J39RE is electrically and mechanically equivalent to the 93J39R. Both components have identical resistance, tolerance, power rating, temperature coefficient, and physical dimensions. The primary difference is packaging format (bulk vs. standard) and RoHS compliance status.

Q: What is the difference between the packaging formats?

A: The 93J39R is supplied in standard packaging, while the 93J39RE is supplied in bulk packaging. Both formats contain the same component with identical specifications. Packaging format selection depends on order quantity requirements and inventory management practices.

Q: Are there any thermal or electrical performance differences between these parts?

A: No. Both parts have identical power ratings (3.25W), temperature coefficients (±30ppm/°C), and resistance values (39 Ohms ±5%). They perform identically in circuit applications.

Q: Which part should be selected for new designs?

A: For new designs, the 93J39RE is recommended due to ROHS3 compliance, which aligns with current regulatory standards and supply chain requirements. The 93J39R remains available for legacy designs or applications with specific non-compliant component requirements.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical axial dimensions of 0.233" diameter by 0.579" length (5.90mm x 14.70mm), ensuring identical PCB footprint and mounting compatibility.
