AC10 Trimmer Capacitor 1-10pF 250V Through Hole Equivalent & Substitute Parts

Part Overview

The AC10 is a 1-10pF trimmer capacitor rated for 250V with top adjustment and through-hole mounting. Manufactured by Knowles Voltronics, this component is classified as Active product status. Identifying equivalent and substitute parts becomes necessary when the primary part reaches end-of-life, inventory constraints occur, or when design flexibility is required across manufacturing sources while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AC10 trimmer capacitor is determined by strict alignment of 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: Through Hole (exact match required)
• Q @ Freq: 5000 @ 100MHz (exact match required)
• Operating Temperature Range: -65°C ~ 125°C (exact match required)

The GAA10007 manufactured by Sprague-Goodman meets all critical electrical parameters. Mechanical dimensions show minor variation in body diameter (0.299" vs 0.250"), which remains within acceptable tolerance for through-hole PCB mounting applications where the component footprint accommodates standard trimmer capacitor spacing.

Parameter Comparison

Engineering Selection Recommendations

The GAA10007 serves as a direct parametric equivalent to the AC10 based on electrical specifications and operating characteristics. Both components share identical capacitance range, voltage rating, adjustment mechanism, dielectric composition, and thermal operating window.

The AC10 maintains Active product status with current inventory availability (1047 pcs). The GAA10007 is classified as Obsolete with limited inventory (745 pcs). Selection between these parts should prioritize the AC10 for new designs and ongoing production due to its active lifecycle status and superior long-term availability assurance.

Both parts satisfy RoHS and ECCN compliance requirements. The GAA10007 carries RoHS Compliant designation while the AC10 specifies ROHS3 Compliant status, indicating alignment with current environmental and trade regulations.

Frequently Asked Questions (FAQ)

Q: Can GAA10007 replace AC10 in existing designs? A: Yes. The GAA10007 meets all critical electrical parameters: 1-10pF capacitance, 250V rating, top adjustment, air dielectric, and identical Q factor at 100MHz. Mechanical compatibility is maintained through matching height (0.500" seated) and standard through-hole mounting. The body diameter difference (0.299" vs 0.250") does not affect PCB footprint compatibility for typical trimmer capacitor layouts.

Q: What is the primary reason to consider substitution? A: The AC10 is Active status with current inventory. Substitution becomes relevant only when AC10 availability is constrained or when design requirements mandate multi-source qualification. The GAA10007 is Obsolete, making it unsuitable for new production planning.

Q: Are there compliance differences between these parts? A: Both parts comply with EAR99 export classification and HTSUS 8532.30.0090 tariff code. The AC10 specifies ROHS3 Compliant while GAA10007 specifies RoHS Compliant. Both designations indicate environmental regulation compliance; ROHS3 represents the current standard revision.

Q: Does the size difference affect circuit performance? A: No. The 0.049" diameter difference (7.60mm vs 6.35mm) is a mechanical variation that does not alter electrical performance. Both components deliver identical capacitance range, voltage rating, and Q factor specifications. PCB layout accommodation remains standard for through-hole trimmer capacitor applications.

Q: What is the operating temperature compatibility? A: Both AC10 and GAA10007 operate across -65°C to 125°C. This identical thermal range ensures equivalent performance across all specified environmental conditions.
