AB10 Trimmer Capacitor Equivalent & Substitute Parts

Part Overview

The AB10 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 tuning and impedance matching applications in electronic circuits. The part maintains Active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts may be required due to inventory constraints, supply chain disruptions, or design revision requirements while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AB10 are qualified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following key 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)
• Q Factor @ 100MHz: 5000 (exact match required)
• Physical Dimensions: 0.300" Dia (7.62mm) and 0.480" (12.19mm) height (exact match required)
• Mounting Type: Through Hole (exact match required)
• Operating Temperature Range: –65°C to 125°C (exact match required)

Only parts meeting all these criteria are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The AF10 is a direct parametric equivalent to the AB10. Both parts are manufactured by Knowles Voltronics within the same A series and share identical electrical specifications, physical dimensions, and environmental ratings. Both parts maintain Active product status and carry equivalent compliance certifications (ROHS3 Compliant, REACH Unaffected). Selection between AB10 and AF10 may be based on inventory availability, lead time, or procurement requirements, as no technical differentiation exists between the two parts.

Frequently Asked Questions (FAQ)
