CAP TRIMMER 6-25PF 250V SMD 9402-6

Part Overview

The Knowles Johanson Manufacturing 9402-6 is a surface mount trimmer capacitor with a capacitance range of 6–25pF and rated voltage of 250V. This component belongs to the Thin-Trim® series and is designed for general-purpose applications requiring adjustable capacitance in compact form factors. The part is currently active in production with full RoHS compliance and unlimited moisture sensitivity rating (MSL 1). Alternative models may be required due to inventory constraints, supply chain considerations, or specific procurement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 9402-6 is determined by strict equivalence across the following critical parameters:

• Capacitance Range: 6–25pF
• Voltage Rating: 250V
• Adjustment Type: Top
• Mounting Type: Surface Mount
• Physical Dimensions: 0.141" Dia (4.68mm), Height 0.040" (1.02mm) maximum
• Operating Temperature Range: –55°C to 125°C
• Series Compatibility: Thin-Trim®
• Compliance: RoHS Compliant, MSL 1

The substitute part 9402-6SL-1 meets all these parameters identically, establishing it as a parametric equivalent within the Thin-Trim® product family.

Parameter Comparison

Engineering Selection Recommendations

Both the 9402-6 and 9402-6SL-1 are active production parts from Knowles Johanson Manufacturing with identical electrical, mechanical, and compliance specifications. Selection between these parts should be based on availability and procurement lead times. Both parts carry RoHS compliance certification and MSL 1 rating, confirming suitability for standard surface mount assembly processes without moisture-related handling restrictions. The parametric equivalence ensures direct interchangeability in circuit designs without modification to PCB layouts, assembly procedures, or electrical performance expectations.

Frequently Asked Questions (FAQ)

Q: Can 9402-6SL-1 be used as a direct replacement for 9402-6 in production?

A: Yes. The 9402-6SL-1 is a parametric equivalent with identical capacitance range (6–25pF), voltage rating (250V), physical dimensions (0.141" Dia, 0.040" height), adjustment type (top), and operating temperature range (–55°C to 125°C). No circuit modifications or PCB layout changes are required.

Q: Are there any differences in RoHS compliance or moisture sensitivity between these parts?

A: No. Both parts are RoHS compliant and carry MSL 1 (unlimited moisture sensitivity level), indicating identical handling and storage requirements.

Q: What is the basis for substitution eligibility?

A: Substitution is based on strict equivalence across capacitance range, voltage rating, adjustment type, mounting type, physical dimensions, operating temperature range, and compliance certifications. The 9402-6SL-1 matches all these parameters identically.

Q: Can these parts be mixed in the same production batch?

A: Yes. Since both parts are parametrically equivalent and from the same manufacturer series (Thin-Trim®), they can be used interchangeably within the same assembly without performance or reliability concerns.

Q: What should drive the selection between 9402-6 and 9402-6SL-1?

A: Selection should be based on inventory availability, supplier lead times, and procurement cost. Electrical and mechanical performance are identical.
