OY39GK Equivalent & Substitute Parts

Part Overview

The OY39GK is a 3.9 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 maintenance and repair operations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OY39GK is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must match the following criteria:

• Resistance value: 3.9 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 OY39GKE meets all these requirements and is identified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The OY39GKE is the direct equivalent substitute for the obsolete OY39GK. Both parts are manufactured by Ohmite and share identical electrical specifications and physical dimensions. The primary distinction is product status: the OY39GK is obsolete while the OY39GKE remains in active production.

The OY39GKE offers an additional advantage in regulatory compliance. It meets ROHS3 requirements, whereas the OY39GK is non-compliant. For applications subject to RoHS regulations, the OY39GKE is the appropriate selection. Both parts maintain REACH unaffected status and carry the same ECCN and HTSUS classifications.

Frequently Asked Questions (FAQ)

Q: Can the OY39GKE be used as a direct replacement for the OY39GK?

A: Yes. The OY39GKE is electrically and mechanically identical to the OY39GK. All critical parameters—resistance, tolerance, power rating, composition, package type, dimensions, and operating temperature range—are equivalent.

Q: What is the difference between OY39GK and OY39GKE?

A: The OY39GK is obsolete, while the OY39GKE is in active production. The OY39GKE also meets ROHS3 compliance standards, whereas the OY39GK does not. Functionally and electrically, they are identical.

Q: Are there any physical differences between these parts?

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

Q: Does the OY39GKE work across the same temperature range?

A: Yes. The OY39GKE operates across the full temperature range of -40°C to 220°C with the same temperature coefficient of -1000/-1600 ppm/°C as the OY39GK.

Q: What packaging options are available for the OY39GKE?

A: The OY39GKE is available in bulk packaging. The OY39GK packaging specification was not provided in the available data.
