AT10N Trimmer Capacitor Equivalent & Substitute Parts

Part Overview

The AT10N is a 1–10pF trimmer capacitor rated for 250V operation with top panel mount adjustment. Manufactured by Knowles Voltronics, this air dielectric component is designed for general-purpose applications requiring precision capacitance tuning in high-voltage circuits. The part is currently active in production. Substitute parts may be required due to inventory constraints, regional availability, or design flexibility in component sourcing.

Substitute Part Grouping Explanation

Substitution eligibility for the AT10N is determined by strict equivalence across the following critical parameters:

• Capacitance range: 1–10pF (exact match required)
• Voltage rating: 250V (exact match required)
• Adjustment type: Top (exact match required)
• Dielectric material: Air (exact match required)
• Mounting type: Panel Mount (exact match required)
• Operating temperature range: –65°C to 125°C (exact match required)
• Q factor @ 100MHz: 5000 (exact match required)

The GAA10001 manufactured by Sprague-Goodman meets all electrical and mechanical substitution criteria. Physical dimensions vary slightly (0.236" diameter vs. 0.300" diameter for the main part), but both components maintain identical height when seated (0.500"), ensuring compatibility in panel mount applications where radial space may be constrained.

Parameter Comparison

Engineering Selection Recommendations

The AT10N is the primary specification for new designs. The GAA10001 is a qualified substitute when the AT10N is unavailable. Both parts satisfy identical electrical performance requirements and operate across the same temperature envelope.

The GAA10001 carries an Obsolete product status, indicating that Sprague-Goodman has discontinued this line. Designs utilizing the GAA10001 should transition to the AT10N for long-term supply chain stability.

Both parts are RoHS compliant and carry identical ECCN (EAR99) and HTSUS (8532.30.0090) classifications, supporting equivalent regulatory and export compliance.

Frequently Asked Questions (FAQ)

Q: Can the GAA10001 replace the AT10N in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: capacitance range, voltage rating, adjustment type, dielectric material, mounting configuration, and operating temperature range. The GAA10001 has a smaller diameter (0.236" vs. 0.300"), which may provide layout advantages in space-constrained applications.

Q: What is the significance of the product status difference?

A: The AT10N is Active (in production), while the GAA10001 is Obsolete (discontinued). New designs should specify the AT10N. Existing designs using the GAA10001 should plan for transition to the AT10N to ensure long-term component availability.

Q: Are there packaging differences between these parts?

A: The AT10N is supplied in standard packaging, while the GAA10001 is supplied in Bulk packaging. Confirm packaging requirements with your procurement department before ordering.

Q: Do both parts meet the same compliance standards?

A: Both parts are RoHS compliant and carry identical ECCN and HTSUS classifications. The AT10N specifies RoHS3 compliance, while the GAA10001 specifies RoHS compliance. Both satisfy regulatory requirements for the stated application.

Q: What inventory levels are available?

A: The AT10N has 872 pieces in stock. The GAA10001 has 1,148 pieces in stock. Verify current availability with your supplier before finalizing component orders.
