Substitute Part Grouping Explanation

Substitution eligibility for the AW68GK is determined by strict equivalence across the following critical parameters:

• Resistance value: 6.8 Ohms
• Tolerance: ±10%
• Power rating: 2.5W
• Composition: Ceramic
• Package configuration: Radial Lead
• Operating temperature range: -55°C ~ 150°C
• Physical dimensions: 0.787" L x 0.512" W with maximum seated height of 0.866"
• Feature set: Flame Retardant Coating, Moisture Resistant, Non-Inductive, Pulse Withstanding, Safety

The AW68GKE meets all substitution criteria as a direct equivalent within the same PulsEater® A series, maintaining identical electrical specifications and mechanical form factor.

Parameter Comparison

Engineering Selection Recommendations

The AW68GKE is the direct functional equivalent of the AW68GK. Both parts are manufactured by Ohmite within the same PulsEater® A series and share identical electrical and mechanical specifications. The primary distinction is product status: the AW68GK is obsolete while the AW68GKE remains in active production.

For new designs or ongoing system support, the AW68GKE is the appropriate selection. The AW68GKE provides ROHS3 compliance, whereas the AW68GK is RoHS non-compliant. Both parts maintain equivalent performance across all specified electrical parameters, operating temperature range, and physical form factor, ensuring direct interchangeability in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the AW68GKE be used as a direct replacement for the AW68GK?
