GAA6R005 Trimmer Capacitor: Equivalent & Substitute Parts

Part Overview

The GAA6R005 is a 0.6–6pF air dielectric trimmer capacitor manufactured by Sprague-Goodman, rated for 250V operation with side adjustment. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning. The part operates across a wide temperature range of –65°C to 125°C and is housed in a compact 0.240" diameter package with a maximum seated height of 0.480".

Key Parameters

Substitute Part Grouping Explanation

Based on the provided substitute list, part number 5718 from Adafruit Industries LLC has been identified as a listed alternative. However, a critical incompatibility exists between the main part and this substitute:

GAA6R005 is a trimmer capacitor (passive component for capacitance adjustment in RF and tuning circuits).

5718 is a general-purpose relay (electromechanical switching device with SPDT contact form, 5–24VDC coil, 12A contact rating).

These components serve fundamentally different functions and operate on different physical principles. The substitute relationship cannot be validated based on electrical or mechanical compatibility. No valid substitution logic exists between a capacitive tuning element and a relay switching device.

Parameter Comparison

Engineering Selection Recommendations

The listed substitute (5718) cannot be applied as a functional replacement for the GAA6R005 due to fundamental category mismatch. The GAA6R005 serves as a variable capacitive element for frequency tuning, impedance matching, and circuit calibration in RF applications. The 5718 is an electromechanical relay designed for load switching and control logic.

For applications requiring the GAA6R005 functionality, alternative trimmer capacitors with equivalent specifications must be sourced from active manufacturers offering:

• Capacitance range: 0.6–6pF
• Voltage rating: 250V minimum
• Air dielectric construction
• Side adjustment mechanism
• Operating temperature range: –65°C to 125°C minimum
• RoHS compliance certification

Current product status (Obsolete) indicates this component is no longer manufactured. Procurement should prioritize identifying active-status trimmer capacitors from current manufacturers with matching electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can the 5718 relay replace the GAA6R005 trimmer capacitor in my circuit?

A: No. The 5718 is a relay (switching device), while the GAA6R005 is a trimmer capacitor (tuning element). These components have different electrical functions and cannot substitute for one another.

Q: Why is the GAA6R005 listed as obsolete?

A: Obsolete status indicates the manufacturer (Sprague-Goodman) has discontinued production. Existing inventory may be available through authorized distributors, but long-term sourcing requires identification of active-status alternatives.

Q: What parameters must an alternative trimmer capacitor match?

A: Critical parameters include capacitance range (0.6–6pF), voltage rating (250V), dielectric type (air), adjustment mechanism (side), temperature range (–65°C to 125°C), and physical dimensions (0.240" diameter, 0.480" max height).

Q: Is the GAA6R005 RoHS compliant?

A: Yes, the GAA6R005 is RoHS compliant. Replacement components should maintain this compliance status for regulatory consistency.

Q: What is the Q factor significance for this trimmer capacitor?

A: The Q factor of 5000 @ 100MHz indicates low-loss performance suitable for high-frequency RF tuning applications. Substitute components should maintain comparable Q characteristics for equivalent circuit performance.

Q: Are there packaging considerations for the GAA6R005?

A: The component is supplied in bulk packaging with a compact footprint (0.240" diameter, 0.480" seated height). Space-constrained applications must verify dimensional compatibility with alternative components.
