OY33GK Equivalent & Substitute Parts

Part Overview

The OY33GK is a 3.3 Ohms ±10% 2W 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 a wide operating temperature range of -40°C to 220°C. The part is currently classified as obsolete, making identification of suitable substitutes essential for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OY33GK is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must match the following criteria:

• Resistance value: 3.3 Ohms
• Tolerance: ±10%
• Power rating: 2W
• Composition: Ceramic
• Package configuration: Axial with 2 terminations
• Physical dimensions: 0.276" Dia x 0.748" L (7.00mm x 19.00mm)
• Operating temperature range: -40°C to 220°C
• Temperature coefficient: -1000/-1600 ppm/°C
• Features: Moisture resistant and pulse withstanding

The OY33GKE meets all these parameters and is classified as an active product, providing continuity for applications currently using the obsolete OY33GK.

Parameter Comparison

Engineering Selection Recommendations

The OY33GKE is the direct equivalent substitute for the obsolete OY33GK. Both parts are manufactured by Ohmite within the OY series and share identical electrical specifications and physical dimensions. The primary distinction is product status: the OY33GK is obsolete while the OY33GKE remains in active production.

For new designs and ongoing production requiring 3.3 Ohms ±10% 2W axial ceramic resistors, the OY33GKE is the appropriate selection. The OY33GKE provides improved compliance status, being ROHS3 compliant compared to the non-compliant OY33GK, while maintaining full electrical and mechanical compatibility. Inventory availability of the OY33GKE (13,654 pieces) ensures supply continuity for production requirements.

Frequently Asked Questions (FAQ)

Q: Can the OY33GKE be used as a direct replacement for the OY33GK?

A: Yes. The OY33GKE is electrically and mechanically identical to the OY33GK. Both parts have the same resistance value (3.3 Ohms), tolerance (±10%), power rating (2W), physical dimensions (0.276" Dia x 0.748" L), operating temperature range (-40°C to 220°C), and ceramic composition with moisture-resistant and pulse-withstanding features.

Q: What is the difference between OY33GK and OY33GKE?

A: The primary differences are product status and compliance. The OY33GK is obsolete, while the OY33GKE is an active product. The OY33GKE is ROHS3 compliant, whereas the OY33GK is RoHS non-compliant. All electrical and mechanical specifications are identical.

Q: Are there any package or lead configuration differences?

A: No. Both parts use identical axial package configuration with 2 terminations and the same physical dimensions of 0.276" Dia x 0.748" L (7.00mm x 19.00mm).

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

A: Both the OY33GK and OY33GKE operate across a temperature range of -40°C to 220°C with a temperature coefficient of -1000/-1600 ppm/°C.

Q: Is the OY33GKE suitable for moisture-sensitive applications?

A: Yes. The OY33GKE features moisture-resistant characteristics and is rated as Not Applicable for Moisture Sensitivity Level (MSL), indicating it does not require special moisture protection during storage or handling.
