Substitute Part Grouping Explanation

The OY68GKE is classified as a direct substitute for the OY68GK based on strict parameter equivalence. Substitution is valid when the following criteria are met:

• Resistance value: 6.8 Ohms (exact match)
• Tolerance: ±10% (exact match)
• Power rating: 2W (exact match)
• Composition: Ceramic (exact match)
• Package type: Axial (exact match)
• Physical dimensions: 0.276" Dia x 0.748" L / 7.00mm x 19.00mm (exact match)
• Operating temperature range: -40°C ~ 220°C (exact match)
• Temperature coefficient: -1000 / -1600 ppm/°C (exact match)
• Features: Moisture Resistant, Pulse Withstanding (exact match)
• Number of terminations: 2 (exact match)

The OY68GKE maintains full electrical and mechanical compatibility with the OY68GK across all specified parameters.

Parameter Comparison

Engineering Selection Recommendations

The OY68GKE is the appropriate selection for applications currently specified with the OY68GK. The substitute part maintains complete electrical and mechanical equivalence across all defined parameters. The transition from OY68GK to OY68GKE is supported by the active product status of the substitute, ensuring long-term availability and supply chain continuity.

The OY68GKE offers improved compliance status, meeting ROHS3 requirements compared to the non-compliant OY68GK. This compliance improvement supports modern procurement standards and regulatory requirements without altering the component's functional performance in the circuit.

Frequently Asked Questions (FAQ)

Q: Can OY68GKE be used as a direct replacement for OY68GK in existing designs?

A: Yes. The OY68GKE provides complete electrical and mechanical equivalence. All critical parameters including resistance value, tolerance, power rating, package dimensions, and operating temperature range are identical. Direct substitution is valid without circuit modification.

Q: What is the difference between OY68GK and OY68GKE?
