AD10 Trimmer Capacitor Equivalent & Substitute Parts

Part Overview

The AD10 is a 1–10pF trimmer capacitor rated for 250V operation with top adjustment and through-hole mounting. Manufactured by Knowles Voltronics, this component is designed for general-purpose applications requiring variable capacitance in the low picofarad range. The part is currently active in production with full RoHS3 compliance and REACH unaffected status. Substitute parts may be required due to inventory constraints, supply chain disruptions, or design flexibility in component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AD10 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: Through Hole (exact match required)
• Physical Dimensions: 0.300" Dia (7.62mm) and 0.480" (12.19mm) height (exact match required)
• Operating Temperature Range: –65°C to 125°C (exact match required)
• Q Factor: 5000 @ 100MHz (exact match required)

The AF10 meets all substitution criteria as a parametric equivalent within the Knowles Voltronics A Series trimmer capacitor family.

Parameter Comparison

Engineering Selection Recommendations

Both AD10 and AF10 are active production components manufactured by Knowles Voltronics with identical electrical and mechanical specifications. Both parts carry ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for industrial and commercial applications. Selection between these parts may be based on inventory availability, lead time, or procurement preference, as they are functionally interchangeable within the specified parameter set.

Frequently Asked Questions (FAQ)

Q: Can the AF10 be used as a direct replacement for the AD10?

A: Yes. The AF10 is a parametric equivalent with identical capacitance range, voltage rating, adjustment type, dielectric material, mounting configuration, physical dimensions, temperature range, and Q factor. Both parts are manufactured by Knowles Voltronics within the A Series family.

Q: Are there any physical compatibility concerns when substituting the AF10 for the AD10?

A: No. Both parts share identical through-hole mounting dimensions (0.300" diameter, 0.480" maximum seated height) and are compatible with the same PCB footprints and assembly processes.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both AD10 and AF10 are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations.

Q: What is the primary difference between the AD10 and AF10?

A: No electrical or mechanical differences exist between these parts. They are equivalent components within the Knowles Voltronics A Series trimmer capacitor product line.

Q: Can these parts be used interchangeably in production?

A: Yes. The AD10 and AF10 are fully interchangeable for applications requiring 1–10pF variable capacitance at 250V with top adjustment and through-hole mounting.
