Substitute Part Grouping Explanation

Substitution of the OX68GK is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications for resistance value, tolerance, power rating, composition type, and physical dimensions to ensure direct compatibility in existing circuit designs and PCB layouts.

The OX68GKE qualifies as a direct substitute based on the following criteria:

• Identical resistance value: 6.8 Ohms
• Identical tolerance: ±10%
• Identical power rating: 1W
• Identical composition: Ceramic
• Identical package type: Axial
• Identical physical dimensions: 0.217" Dia x 0.650" L (5.50mm x 16.50mm)
• Identical operating temperature range: -40°C ~ 220°C
• Identical temperature coefficient: -1000 / -1600 ppm/°C
• Identical features: Moisture Resistant, Pulse Withstanding
• Identical number of terminations: 2

Parameter Comparison

Engineering Selection Recommendations

The OX68GKE is the direct equivalent substitute for the obsolete OX68GK. Both components are manufactured by Ohmite and share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: the OX68GK is obsolete while the OX68GKE maintains active production status.

For new designs and ongoing production requiring this component specification, the OX68GKE is the appropriate selection. The OX68GKE additionally provides ROHS3 compliance, offering improved environmental and regulatory alignment compared to the non-compliant OX68GK. Both components maintain REACH Unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can the OX68GKE directly replace the OX68GK in existing applications?

A: Yes. The OX68GKE is electrically and mechanically identical to the OX68GK across all specified parameters, including resistance value, tolerance, power rating, physical dimensions, and operating temperature range. Direct substitution is appropriate for circuit designs and PCB layouts originally specified for the OX68GK.

Q: What is the primary reason to transition from OX68GK to OX68GKE?

A: The OX68GK is classified as obsolete, while the OX68GKE maintains active production status. The OX68GKE ensures continued component availability and supply chain reliability for applications requiring this specification.

Q: Are there packaging differences between OX68GK and OX68GKE?

A: The OX68GKE is supplied in bulk packaging, while the OX68GK packaging designation is not specified. Both components maintain identical physical dimensions and axial lead configuration, ensuring compatibility with existing PCB designs and assembly processes.

Q: Does the OX68GKE offer improved compliance compared to the OX68GK?

A: The OX68GKE is ROHS3 compliant, whereas the OX68GK is RoHS non-compliant. Both components maintain REACH Unaffected status. Applications subject to RoHS requirements should specify the OX68GKE.

Q: Are the electrical characteristics identical between OX68GK and OX68GKE?

A: Yes. Both components share identical resistance value (6.8 Ohms), tolerance (±10%), power rating (1W), temperature coefficient (-1000 / -1600 ppm/°C), and operating temperature range (-40°C ~ 220°C).
