OX332KE Equivalent & Substitute Parts

Part Overview

The OX332KE is a 3.3 kOhms ±10% 1W through-hole resistor in axial configuration, manufactured by Ohmite. This ceramic composition resistor is designed for applications requiring moisture resistance and pulse withstanding capability. The part is currently active in production and maintains full inventory availability. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when packaging requirements differ.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OX332KE is determined by the following critical parameters:

• Electrical Specifications: Resistance value (3.3 kOhms), tolerance (±10%), and power rating (1W) must be identical
• Package Configuration: Axial through-hole package type is required for mechanical compatibility
• Composition: Ceramic composition maintains performance characteristics
• Compliance: RoHS3 compliance and REACH unaffected status must be maintained

The OC1K332E-TR qualifies as a manufacturer-recommended substitute based on matching all critical electrical and mechanical parameters within the allowed specification range.

Parameter Comparison

Engineering Selection Recommendations

Both the OX332KE and OC1K332E-TR are active production parts from Ohmite with ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

• Packaging Requirements: OX332KE is supplied in bulk packaging, while OC1K332E-TR is supplied in cut tape format. Choose based on assembly process requirements.
• Temperature Operating Range: OC1K332E-TR provides an extended operating temperature range (-55°C ~ 230°C) compared to OX332KE (-40°C ~ 220°C). Select OC1K332E-TR for applications requiring operation below -40°C or above 220°C.
• Inventory Availability: Both parts maintain active inventory status with sufficient stock levels for production requirements.

Frequently Asked Questions (FAQ)

Q: Can OC1K332E-TR be used as a direct replacement for OX332KE?

A: Yes. Both parts share identical electrical specifications (3.3 kOhms, ±10%, 1W), ceramic composition, axial package configuration, and compliance certifications. The primary difference is packaging format (bulk versus cut tape) and operating temperature range.

Q: What is the difference in physical dimensions between these parts?

A: OX332KE has a diameter of 0.217" (5.50mm), while OC1K332E-TR has a diameter of 0.311" (7.90mm). Both maintain the same 0.650" (16.50mm) length. Verify PCB layout compatibility before substitution.

Q: Are there any feature differences between OX332KE and OC1K332E-TR?

A: OX332KE features moisture resistance and pulse withstanding capability. OC1K332E-TR features high voltage and pulse withstanding capability. Both are ceramic composition resistors suitable for their respective application requirements.

Q: Which part should be selected for high-temperature applications?

A: OC1K332E-TR supports operation up to 230°C, compared to OX332KE at 220°C. For applications requiring maximum temperature margin, OC1K332E-TR is the appropriate selection.

Q: Do both parts meet the same compliance standards?

A: Yes. Both OX332KE and OC1K332E-TR are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.
