EE10 Trimmer Capacitor Equivalent & Substitute Parts

Part Overview

The EE10 is a 0.8–10pF trimmer capacitor rated for 250V with top adjustment and through-hole mounting, manufactured by Knowles Voltronics. This component is classified as obsolete, making identification of compatible substitutes essential for ongoing system support and design updates. The EE10 belongs to the general-purpose trimmer capacitor category and is suitable for applications requiring precision capacitance adjustment in high-voltage environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EE10 is determined by the following critical parameters:

• Capacitance Range: The substitute must cover or encompass the required adjustment range. The EE10 operates from 0.8–10pF; acceptable substitutes must support this range or a compatible subset.
• Voltage Rating: The substitute must maintain or exceed the 250V rated voltage to ensure safe operation in the intended application.
• Adjustment Type: Top adjustment is required to maintain mechanical compatibility with existing designs.
• Mounting Type: Through-hole mounting is mandatory for PCB compatibility.
• Physical Dimensions: The 0.300" diameter and 0.480" maximum seated height must be preserved to ensure mechanical fit.
• Operating Temperature Range: The –65°C to 125°C range must be supported.
• Q Factor: The 5000 @ 100MHz specification indicates performance expectations for high-frequency applications.

The AE10 qualifies as a direct substitute based on these parameters, with the exception of capacitance range (1–10pF versus 0.8–10pF) and dielectric material (Air versus PTFE).

Parameter Comparison

Engineering Selection Recommendations

The AE10 is the qualified substitute for the obsolete EE10. Both components share identical electrical ratings (250V), mechanical dimensions (0.300" diameter, 0.480" height), adjustment type (top), mounting configuration (through-hole), and performance characteristics (Q factor of 5000 @ 100MHz).

The AE10 is currently in active production status with ROHS3 compliance and REACH unaffected certification, providing supply chain continuity and regulatory compliance assurance. The capacitance range difference (1–10pF versus 0.8–10pF) represents a 0.2pF minimum offset; applications requiring capacitance values below 1pF must be evaluated against circuit requirements.

The dielectric material difference (Air versus PTFE) affects temperature stability and frequency response characteristics; however, both materials are standard for general-purpose trimmer capacitor applications at the specified voltage and frequency ratings.

Frequently Asked Questions (FAQ)

Q: Can the AE10 directly replace the EE10 in existing designs?

A: The AE10 is mechanically and electrically compatible with the EE10 for through-hole PCB applications. Both components have identical physical dimensions, voltage ratings, adjustment mechanisms, and operating temperature ranges. The primary consideration is the capacitance range minimum: the AE10 starts at 1pF while the EE10 starts at 0.8pF. If your circuit requires adjustment below 1pF, alternative solutions must be evaluated.

Q: What is the significance of the dielectric material difference?

A: The EE10 uses PTFE dielectric while the AE10 uses Air dielectric. Both are suitable for general-purpose applications at 250V and 100MHz. PTFE offers improved temperature stability, while Air dielectric provides lower loss characteristics. The choice depends on specific application requirements for frequency response and temperature compensation.

Q: Are there compliance or supply chain advantages to using the AE10?

A: Yes. The AE10 is in active production with ROHS3 compliance and REACH unaffected status, ensuring ongoing availability and regulatory alignment. The EE10 is obsolete, making the AE10 the recommended long-term solution for new designs and production continuity.

Q: What packaging options are available?

A: The EE10 is supplied in standard packaging, while the AE10 is available in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Are there inventory considerations?

A: Both components are currently in stock. The EE10 has 949 pieces available, and the AE10 has 1084 pieces available. For long-term projects, the AE10 is recommended due to its active production status.
