Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following critical parameters across all candidates:

• Resistance value: 33 Ohms
• Tolerance: ±5%
• Power rating: 3.25W
• Composition: Wirewound
• Package: Axial
• Temperature coefficient: ±30ppm/°C
• Termination count: 2
• HTSUS classification: 8533.21.0080

All identified substitutes meet these core electrical and mechanical specifications. Variations in physical dimensions, protective coatings, and compliance certifications are noted but do not affect functional interchangeability within the specified parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

93J33RE (Ohmite): This part is a parametric equivalent to the 93J33R with identical electrical specifications and physical dimensions. The primary distinction is RoHS3 compliance status. Selection of 93J33RE is appropriate for applications subject to RoHS3 regulatory requirements or when compliance documentation is mandated. Inventory availability is higher at 1132 units.

CW02C33R00JE70 (Vishay Dale): This part meets all core electrical parameters and is RoHS3 compliant. Physical dimensions are slightly smaller (0.218" Dia x 0.500" L versus 0.233" Dia x 0.579" L), which may be advantageous in space-constrained layouts. The operating temperature range is specified as -65°C to 350°C. This part is suitable for applications where dimensional optimization or extended temperature documentation is required. Inventory availability is highest at 1579 units.

Selection between these substitutes should be based on compliance requirements, available inventory, and physical space constraints within the target application.

Frequently Asked Questions (FAQ)

Q: Can 93J33RE be used as a direct replacement for 93J33R?

A: Yes. Both parts share identical electrical specifications (33 Ohms, ±5%, 3.25W, ±30ppm/°C) and physical dimensions (0.233" Dia x 0.579" L). The primary difference is RoHS3 compliance status. Functional interchangeability is complete.

Q: What is the difference between the Ohmite and Vishay Dale options?

A: All three parts meet the core electrical requirements. The Vishay Dale CW02C33R00JE70 has slightly smaller physical dimensions (0.218" Dia x 0.500" L) and includes an explicit operating temperature range specification (-65°C to 350°C). Both Vishay Dale and the 93J33RE are RoHS3 compliant, while the original 93J33R is not.

Q: Are there any dimensional compatibility concerns when substituting the Vishay Dale part?

A: The Vishay Dale CW02C33R00JE70 is approximately 0.079" shorter in length and 0.015" smaller in diameter. In most through-hole applications, this size reduction presents no compatibility issues. However, designs with tight mechanical constraints or specific lead-length requirements should verify fit before implementation.

Q: Which substitute offers the best inventory availability?

A: The Vishay Dale CW02C33R00JE70 has the highest inventory level at 1579 units, followed by the Ohmite 93J33RE at 1132 units.

Q: Do all substitutes carry the same certifications?

A: The 93J33R is RoHS non-compliant. Both 93J33RE and CW02C33R00JE70 are RoHS3 compliant. All three parts carry EAR99 ECCN classification and share the same HTSUS code (8533.21.0080).
