Substitute Part Grouping Explanation

Substitution of the OX332K is based on strict equivalence across the following critical parameters:

• Resistance value: 3.3 kOhms
• Tolerance: ±10%
• Power rating: 1W
• Composition: Ceramic
• Package configuration: Axial
• Physical dimensions: 0.217" Dia x 0.650" L (5.50mm x 16.50mm)
• Operating temperature range: -40°C ~ 220°C
• Functional features: Moisture Resistant, Pulse Withstanding

The OX332KE meets all substitution criteria as a direct equivalent manufactured by Ohmite with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The OX332KE is the direct substitute for the obsolete OX332K. Both components are manufactured by Ohmite and share identical electrical and mechanical specifications. The primary distinction is product status: the OX332K is obsolete while the OX332KE is active and currently available.

The OX332KE provides an additional compliance advantage: it is ROHS3 compliant, whereas the OX332K is RoHS non-compliant. For applications requiring regulatory compliance with modern environmental standards, the OX332KE is the appropriate selection. Both components maintain REACH Unaffected status and EAR99 ECCN classification.

Frequently Asked Questions (FAQ)

Q: Can the OX332KE be used as a direct replacement for the OX332K?

A: Yes. The OX332KE is electrically and mechanically equivalent to the OX332K. Both components have identical resistance values (3.3 kOhms), tolerance (±10%), power rating (1W), package type (Axial), and physical dimensions (0.217" Dia x 0.650" L). They are interchangeable in circuit applications.

Q: What is the primary reason to substitute the OX332K?

A: The OX332K is classified as obsolete. The OX332KE is the active equivalent part from the same manufacturer, ensuring continued availability and supply chain reliability.

Q: Are there any compliance differences between these parts?

A: Yes. The OX332KE is ROHS3 compliant, while the OX332K is RoHS non-compliant. For applications subject to RoHS regulations, the OX332KE is required. Both parts maintain REACH Unaffected status.

Q: Do the physical dimensions match exactly?

A: Yes. Both the OX332K and OX332KE have identical dimensions of 0.217" Dia x 0.650" L (5.50mm x 16.50mm), ensuring compatibility with existing PCB layouts and mechanical assemblies.

Q: What is the operating temperature range for these resistors?

A: Both components operate across the temperature range of -40°C to 220°C, with a temperature coefficient of -1000/-1600ppm/°C.

Q: Are moisture and pulse withstanding characteristics maintained in the substitute?

A: Yes. The OX332KE retains the moisture resistant and pulse withstanding features of the OX332K, maintaining functional equivalence for applications requiring these characteristics.
