Parameter Comparison

Engineering Selection Recommendations

The AY33GKE is the direct substitute for the obsolete AY33GK. Both components are manufactured by Ohmite within the PulsEater® A series and maintain identical electrical specifications and physical dimensions. The AY33GKE offers the advantage of active product status, ensuring continued availability and supply chain reliability. Additionally, the AY33GKE achieves ROHS3 compliance, whereas the AY33GK is RoHS non-compliant. Both components maintain REACH Unaffected status and EAR99 ECCN classification. Selection of the AY33GKE is appropriate for applications requiring equivalent performance with improved regulatory compliance and product lifecycle support.

Frequently Asked Questions (FAQ)

Q: Can the AY33GKE be used as a direct replacement for the AY33GK?

A: Yes. The AY33GKE is a direct equivalent. Both components share identical resistance (3.3 Ohms), tolerance (±10%), power rating (4.5W), composition (ceramic), operating temperature range (-55°C ~ 150°C), and physical dimensions (0.984" L x 0.827" W, height 1.102" max). Radial lead configuration and feature set are identical.

Q: What is the primary difference between these two parts?

A: The AY33GK is obsolete, while the AY33GKE maintains active product status. The AY33GKE also achieves ROHS3 compliance, whereas the AY33GK is RoHS non-compliant.

Q: Are there any mechanical compatibility concerns when substituting the AY33GKE for the AY33GK?

A: No. Both components are radial lead resistors with identical dimensions and height specifications. PCB footprint and mounting requirements are equivalent.

Q: Does the AY33GKE maintain the same feature set as the AY33GK?

A: Yes. Both components include flame retardant coating, moisture resistance, non-inductive design, pulse withstanding capability, and safety features.

Q: What packaging options are available for the AY33GKE?

A: The AY33GKE is supplied in bulk packaging, whereas the AY33GK packaging specification was not provided in the original documentation.
