OX33GK Equivalent & Substitute Parts

Part Overview

The OX33GK is a 3.3 Ohms ±10% 1W through-hole resistor with axial leads, manufactured by Ohmite. This ceramic composition resistor features moisture-resistant and pulse-withstanding characteristics, designed for applications requiring reliable performance across the -40°C to 220°C operating temperature range. The part is currently classified as obsolete, necessitating identification of suitable alternatives for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution of the OX33GK is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical resistance value (3.3 Ohms), tolerance (±10%), power rating (1W), composition (ceramic), package configuration (axial), physical dimensions (0.217" Dia x 0.650" L), operating temperature range (-40°C ~ 220°C), and functional features (moisture resistant, pulse withstanding).

The OX33GKE qualifies as a direct substitute based on complete parameter alignment with the OX33GK. Both parts share identical electrical specifications, physical dimensions, and performance characteristics. The primary distinction is product status and compliance certification.

Engineering Selection Recommendations

The OX33GKE is the direct substitute for the obsolete OX33GK. Both parts are electrically and mechanically identical across all specified parameters. Selection between these parts should be based on product status and regulatory compliance requirements.

The OX33GK remains available in limited inventory (802 pieces) but carries obsolete status with RoHS non-compliance certification. The OX33GKE is actively manufactured, offers significantly higher inventory availability (15685 pieces), and meets ROHS3 compliance standards. For new designs and ongoing production requiring regulatory compliance, the OX33GKE is the appropriate selection. For legacy system maintenance where RoHS compliance is not a requirement, either part provides equivalent electrical and mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can OX33GKE be used as a direct replacement for OX33GK in existing designs?

A: Yes. The OX33GKE provides complete electrical and mechanical equivalence to the OX33GK. All critical parameters including resistance, tolerance, power rating, package type, dimensions, and operating temperature range are identical. Direct substitution is possible without circuit modification.

Q: What is the primary difference between OX33GK and OX33GKE?

A: The OX33GKE is the active production variant of the OX33GK. The main differences are product status (active vs. obsolete), RoHS compliance (ROHS3 compliant vs. non-compliant), and packaging designation (bulk vs. unspecified). Electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns when substituting OX33GKE for OX33GK?

A: No compatibility concerns exist. Both parts share identical axial package configuration, physical dimensions (0.217" Dia x 0.650" L), and two-termination design. PCB footprints and circuit layouts require no modification.

Q: Which part should be selected for new production?

A: The OX33GKE should be selected for new production. It is actively manufactured, offers superior inventory availability, and meets current ROHS3 compliance requirements. The OX33GK is obsolete and should be reserved for legacy system maintenance only.

Q: Are the temperature coefficients identical between both parts?

A: Yes. Both OX33GK and OX33GKE maintain identical temperature coefficient specifications of -1000 / -1600 ppm/°C and operate across the same temperature range of -40°C to 220°C.
