Key Parameters

Substitute Part Grouping Explanation

Substitution of the GKG30066-07 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance range: 6.5–30pF (exact match required)
• Voltage rating: 100V (minimum requirement)
• Dielectric material: Ceramic (functional requirement)
• Q factor @ 1MHz: 300 (performance specification)

Mechanical Parameters:

• Adjustment type: Top (design constraint)
• Mounting type: Surface Mount (assembly requirement)
• Footprint dimensions: 0.177" L × 0.157" W / 4.50mm × 4.00mm (PCB layout constraint)
• Operating temperature range: –25°C to +85°C (environmental requirement)

Compliance Parameters:

• Moisture Sensitivity Level: 1 (Unlimited) (handling and storage requirement)
• ECCN: EAR99 (export compliance)

The GKG30086-05 meets all critical electrical and mechanical parameters and is classified as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

GKG30086-05 as Primary Substitute:

The GKG30086-05 is a direct parametric equivalent to the GKG30066-07. Both components share identical electrical specifications (capacitance range, voltage rating, dielectric material, and Q factor), identical mechanical mounting characteristics (surface mount, top adjustment, footprint dimensions), and identical compliance classifications (MSL 1, ECCN EAR99).

The only dimensional variation is seated height: GKG30066-07 specifies 0.106" (2.70mm) maximum, while GKG30086-05 specifies 0.118" (3.00mm) maximum. This 0.012" (0.30mm) difference must be evaluated against PCB clearance requirements and assembly constraints specific to the application.

Both parts are obsolete. Current inventory availability is 1,116 units for GKG30066-07 and 935 units for GKG30086-05. Selection should prioritize application-specific height constraints and inventory requirements.

Frequently Asked Questions (FAQ)

Q: Can GKG30086-05 be used as a direct replacement for GKG30066-07?

A: Yes, provided that the seated height difference of 0.012" (0.30mm) does not violate PCB clearance or assembly constraints. All electrical and mechanical parameters are identical.

Q: What is the significance of the height variation between these parts?

A: The GKG30086-05 has a maximum seated height of 0.118" (3.00mm) compared to 0.106" (2.70mm) for the GKG30066-07. This difference must be verified against PCB layout, component clearance zones, and assembly equipment specifications to ensure compatibility.

Q: Are both parts subject to the same handling and storage requirements?

A: Yes. Both components carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions for handling, storage, or shelf life.

Q: What compliance certifications apply to both parts?

A: Both GKG30066-07 and GKG30086-05 are classified under ECCN EAR99 and are REACH Unaffected. Export and regulatory compliance requirements are identical.

Q: Why are both parts classified as obsolete?

A: Obsolete status indicates that these components are no longer in active production by Sprague-Goodman. Substitution is necessary for ongoing supply requirements. Current inventory availability should be confirmed with authorized distributors.

Q: Are there any performance differences between these parts?

A: No. Both parts specify identical Q factor (300 @ 1MHz), operating temperature range (–25°C to +85°C), and all electrical parameters. Performance is equivalent.
