Substitute Part Grouping Explanation

Substitute parts for the Ohmite 93J7R5 are identified based on electrical and mechanical parameter equivalence. The primary substitution criterion is parametric matching across the following key specifications:

• Resistance value: 7.5 Ohms
• Tolerance: ±5%
• Power rating: 3.25W
• Composition: Wirewound
• Package configuration: Axial
• Temperature coefficient: ±100ppm/°C
• Physical dimensions: 0.233" Dia x 0.579" L (5.90mm x 14.70mm)
• Termination count: 2

The Ohmite 93J7R5E meets all electrical and mechanical parameters required for direct substitution. Packaging differences (Bulk versus standard) do not affect functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the Ohmite 93J7R5 and 93J7R5E are Active status components suitable for circuit applications requiring 7.5 Ohm 3.25W axial wirewound resistors. Selection between these parts should consider regulatory compliance requirements:

The 93J7R5E offers ROHS3 compliance, making it the preferred choice for applications subject to RoHS regulations. The 93J7R5 is RoHS non-compliant and should be selected only when RoHS compliance is not a requirement.

Both parts share identical electrical specifications, mechanical dimensions, and thermal characteristics. Packaging format (Bulk for 93J7R5E versus standard for 93J7R5) does not affect functional performance in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the 93J7R5E directly replace the 93J7R5 in existing designs?

A: Yes. The 93J7R5E is a parametric equivalent with identical resistance value (7.5 Ohms), tolerance (±5%), power rating (3.25W), composition (Wirewound), package type (Axial), and physical dimensions (0.233" Dia x 0.579" L). Both components are from the Ohmite 90 series and share the same electrical and mechanical characteristics.

Q: What is the difference between the 93J7R5 and 93J7R5E?

A: The primary difference is RoHS compliance status. The 93J7R5E is ROHS3 compliant, while the 93J7R5 is RoHS non-compliant. Both parts are otherwise electrically and mechanically identical. Packaging format also differs (Bulk for 93J7R5E).

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

A: No. Both parts have identical temperature coefficients (±100ppm/°C), power ratings (3.25W), and all other electrical specifications. Thermal and electrical performance is equivalent.

Q: Which part should I select for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS compliance, select the 93J7R5E. For applications without RoHS requirements, either part is suitable based on availability and procurement preferences.

Q: Are the physical dimensions identical?

A: Yes. Both the 93J7R5 and 93J7R5E have identical dimensions of 0.233" Dia x 0.579" L (5.90mm x 14.70mm) and are both axial package configuration, ensuring identical PCB layout compatibility.
