OX39GK Equivalent & Substitute Parts

Part Overview

The OX39GK is a 3.9 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 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 design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the OX39GK is determined by strict equivalence across the following electrical and mechanical parameters:

• Resistance value: 3.9 Ohms
• Tolerance: ±10%
• Power rating: 1W
• Composition: Ceramic
• Package configuration: Axial with 2 terminations
• Physical dimensions: 0.217" Dia x 0.650" L (5.50mm x 16.50mm)
• Operating temperature range: -40°C ~ 220°C
• Temperature coefficient: -1000 / -1600 ppm/°C
• Features: Moisture Resistant, Pulse Withstanding

The OX39GKE meets all these criteria and is classified as a direct equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The OX39GKE is the direct equivalent substitute for the obsolete OX39GK. Both components are manufactured by Ohmite within the same OX series and share identical electrical specifications and physical dimensions. The primary distinction is product status: the OX39GK is obsolete while the OX39GKE remains in active production.

For new designs or component replenishment, the OX39GKE is the appropriate selection. The OX39GKE provides the additional advantage of ROHS3 compliance, whereas the OX39GK is RoHS non-compliant. Both components carry the same ECCN (EAR99) and HTSUS (8533.21.0090) classifications.

Frequently Asked Questions (FAQ)

Q: Can the OX39GKE directly replace the OX39GK in existing designs?

A: Yes. The OX39GKE is electrically and mechanically identical to the OX39GK. Both components feature the same 3.9 Ohm resistance, ±10% tolerance, 1W power rating, ceramic composition, axial package configuration, and operating temperature range. Physical dimensions are identical at 0.217" Dia x 0.650" L (5.50mm x 16.50mm).

Q: What is the difference between OX39GK and OX39GKE?

A: The primary differences are product status and regulatory compliance. The OX39GK is classified as obsolete, while the OX39GKE is in active production. The OX39GKE is ROHS3 compliant, whereas the OX39GK is RoHS non-compliant. All electrical and mechanical parameters are identical.

Q: Are there any packaging differences between these parts?

A: The OX39GK packaging designation is listed as "-" (unspecified), while the OX39GKE is supplied in Bulk packaging. Both components maintain the same axial lead configuration and physical dimensions.

Q: What certifications apply to both parts?

A: Both the OX39GK and OX39GKE carry ECCN classification EAR99 and HTSUS code 8533.21.0090. The OX39GKE additionally meets ROHS3 compliance requirements. Both are REACH Unaffected and have Moisture Sensitivity Level (MSL) classified as Not Applicable.

Q: Why is the OX39GK marked as obsolete?

A: The OX39GK has been superseded by the OX39GKE within Ohmite's product line. The OX39GKE provides equivalent performance with the added benefit of active production status and improved regulatory compliance.
