GAA14004 Trimmer Capacitor Equivalent & Substitute Parts

Part Overview

The GAA14004 is a 1–14pF air dielectric trimmer capacitor manufactured by Sprague-Goodman, rated for 250V operation with side adjustment. This component is classified as obsolete, making identification of functional equivalents essential for ongoing maintenance, repair, and legacy system support. The AIRTRIM® GAA series was designed for general-purpose applications requiring precision capacitance adjustment in high-voltage environments.

Due to its obsolete status, sourcing direct replacements from the original manufacturer is no longer feasible. Equivalent substitute parts must satisfy the same electrical performance envelope and physical mounting constraints to ensure drop-in compatibility.

Substitute Part Grouping Explanation

Substitution of the GAA14004 is based on functional equivalence within the trimmer capacitor category. The substitute part identified is the Knowles Johanson Manufacturing model 5401, classified as a direct manufacturer equivalent.

Substitution Logic:

The 5401 is grouped as a direct substitute because it belongs to the same functional category (trimmer capacitor) and carries identical regulatory classifications (ECCN: EAR99; HTSUS: 8532.30.0090). Both components share Moisture Sensitivity Level 1 (Unlimited), indicating compatible handling requirements.

Critical Parameters for Substitution Matching:

• Capacitance range compatibility (1–14pF envelope)
• Voltage rating adequacy (≥250V)
• Dielectric type (air dielectric preferred for stability)
• Adjustment mechanism (side adjustment for mechanical interface)
• Physical dimensions (diameter and height within tolerance)
• Operating temperature range overlap (–65°C to 125°C minimum)
• RoHS compliance status

The 5401 substitute part is listed with incomplete technical specifications in available documentation. Verification of dimensional and electrical parameters against the GAA14004 baseline is required before final selection.

Parameter Comparison

Engineering Selection Recommendations

Regulatory and Compliance Status:

Both the GAA14004 and the 5401 substitute carry identical regulatory designations (ECCN: EAR99; HTSUS: 8532.30.0090), confirming compatibility within export control and tariff classification frameworks. Both components meet Moisture Sensitivity Level 1 (Unlimited), eliminating special handling constraints.

Product Status Consideration:

The GAA14004 is classified as obsolete, while the 5401 is in active production. Selection of the 5401 provides access to current manufacturing and supply chain continuity. However, the incomplete technical specification data for the 5401 in available documentation creates a gap in direct parameter verification.

Selection Basis:

The 5401 is identified as a direct manufacturer equivalent based on functional category alignment and regulatory compliance matching. The substitute is suitable for applications where the original GAA14004 specifications can be confirmed to align with the 5401 electrical and mechanical envelope through manufacturer datasheets or technical documentation review.

Frequently Asked Questions (FAQ)

Q: Why is the GAA14004 being replaced?

A: The GAA14004 is classified as obsolete by the original manufacturer, Sprague-Goodman. Continued sourcing from original inventory is limited. The 5401 substitute is in active production, ensuring long-term availability.

Q: What makes the 5401 a suitable substitute for the GAA14004?

A: Both components are trimmer capacitors with identical regulatory classifications (ECCN: EAR99; HTSUS: 8532.30.0090) and moisture sensitivity levels (MSL 1). The 5401 is designated as a direct manufacturer equivalent within the trimmer capacitor category.

Q: Are the physical dimensions identical between the GAA14004 and 5401?

A: The GAA14004 specifies a diameter of 0.303" (7.62mm) and maximum seated height of 0.500" (12.70mm). The 5401 technical specifications for these parameters are not provided in available documentation. Dimensional verification against manufacturer datasheets is necessary before final selection.

Q: Will the 5401 operate at 250V like the GAA14004?

A: The GAA14004 is rated for 250V operation. The voltage rating for the 5401 is not specified in available documentation. Confirmation of voltage rating adequacy is required through manufacturer technical data.

Q: Does the 5401 have the same capacitance range as the GAA14004?

A: The GAA14004 covers 1–14pF. The capacitance range for the 5401 is not specified in available documentation. Verification of capacitance range compatibility is necessary before substitution.

Q: What is the adjustment mechanism for the 5401?

A: The GAA14004 features side adjustment. The adjustment type for the 5401 is not specified in available documentation. Confirmation of side adjustment compatibility is required.

Q: Are both parts RoHS compliant?

A: The GAA14004 is RoHS compliant. RoHS compliance status for the 5401 is not explicitly stated in available documentation, though both share identical HTSUS classification, suggesting regulatory alignment.

Q: What is the operating temperature range for the 5401?

A: The GAA14004 operates from –65°C to 125°C. The operating temperature range for the 5401 is not specified in available documentation. Temperature range verification is necessary for environmental specification matching.

Q: Can the 5401 be used as a direct drop-in replacement?

A: The 5401 is classified as a direct manufacturer equivalent. However, due to incomplete technical specification data, physical and electrical parameter verification against the GAA14004 baseline is required before confirming drop-in compatibility.

Q: What packaging is available for the 5401?

A: The 5401 is available in bulk packaging. The GAA14004 packaging specification is listed as user-defined. Packaging format should be confirmed based on assembly requirements.
