Substitute Part Grouping Explanation

Substitute parts for the 93J91R are identified based on strict parametric equivalence. The following criteria determine substitutability:

• Resistance value: 91 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 3.25W (exact match required)
• Composition: Wirewound (exact match required)
• Package type: Axial (exact match required)
• Physical dimensions: 0.233" Dia x 0.579" L (exact match required)
• Temperature coefficient: ±30ppm/°C (exact match required)
• Features: Flame retardant coating and safety characteristics (exact match required)

The 93J91RE meets all parametric requirements for direct substitution with the 93J91R. The primary difference is packaging format (Bulk versus standard packaging) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 93J91R and 93J91RE are Active status components manufactured by Ohmite with identical electrical and mechanical specifications. Selection between these parts is determined by compliance and packaging requirements:

The 93J91R is suitable for applications where RoHS non-compliant components are acceptable and standard packaging is required.

The 93J91RE is the appropriate selection for applications requiring ROHS3 compliance. This substitute provides higher inventory availability (1053 pieces versus 813 pieces) and is supplied in Bulk packaging format.

Both parts carry identical ECCN (EAR99) and HTSUS (8533.21.0080) classifications.

Frequently Asked Questions (FAQ)

Q: Can the 93J91RE replace the 93J91R in all applications?

A: The 93J91RE is a parametric equivalent with identical electrical and mechanical specifications. The primary difference is RoHS3 compliance status. Substitution is valid where compliance requirements permit or require the ROHS3 compliant version.

Q: What is the difference between standard and Bulk packaging?

A: Packaging format affects order quantity and handling. Standard packaging is the original format for the 93J91R. Bulk packaging for the 93J91RE accommodates larger quantity orders. Both formats contain the same component with identical specifications.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both the 93J91R and 93J91RE share identical dimensions of 0.233" Dia x 0.579" L (5.90mm x 14.70mm), ensuring mechanical compatibility in PCB layouts and through-hole applications.

Q: What does the temperature coefficient ±30ppm/°C indicate?

A: The temperature coefficient specifies the resistance change per degree Celsius. A ±30ppm/°C rating indicates the resistance value will vary by a maximum of 30 parts per million for each degree of temperature change, within the specified operating range.

Q: Why would I choose the 93J91R over the 93J91RE if both are equivalent?

A: Selection depends on specific project requirements. The 93J91R may be chosen if RoHS non-compliant components are acceptable or required by legacy system specifications. The 93J91RE is selected when ROHS3 compliance is mandatory.
