Bourns 3364W-1-102G Trimmer Potentiometer Equivalent & Substitute Parts

Part Overview

The Bourns 3364W-1-102G is a 1 kOhm surface mount trimmer potentiometer with 0.2W power rating, J lead termination, and top adjustment capability. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing production and maintenance applications. The 3364W series represents an earlier generation of the Trimpot® open frame trimmer line. Locating functionally equivalent alternatives ensures design continuity and supply chain reliability for systems currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 3364W-1-102G is determined by the following critical parameters that must remain constant or compatible:

• Resistance value: 1 kOhms (exact match required)
• Termination style: J Lead (mechanical and electrical compatibility)
• Adjustment type: Top Adjustment (functional requirement)
• Mounting type: Surface Mount (PCB assembly compatibility)
• Resistive material: Cermet (performance characteristics)
• Temperature coefficient: ±250ppm/°C (thermal stability requirement)
• Tolerance: ±25% (accuracy specification)

The Bourns TC33X-1-102E qualifies as a substitute based on matching all critical parameters. The TC33X series represents the active production successor to the obsolete 3364W series. While the TC33X-1-102E features a reduced power rating of 0.1W compared to the 3364W-1-102G's 0.2W, this represents a conservative design change suitable for applications where the original 0.2W specification provides design margin. The slightly smaller physical footprint (0.150" x 0.142" versus 0.177" x 0.150") is compatible with standard surface mount assembly processes.

Parameter Comparison

Engineering Selection Recommendations

The TC33X-1-102E is the designated substitute for the obsolete 3364W-1-102G based on the following engineering criteria:

All electrical parameters match the original specification: resistance, tolerance, temperature coefficient, and adjustment characteristics are identical. The substitute maintains ROHS3 compliance and unlimited moisture sensitivity rating, ensuring regulatory and environmental compatibility with the original design.

The reduced power rating of 0.1W in the TC33X-1-102E versus 0.2W in the 3364W-1-102G is acceptable for substitution when the original design includes power dissipation margin. Applications operating at or near the 0.2W limit require thermal analysis to confirm the 0.1W rating is sufficient.

The TC33X series is in active production status with established supply chain availability, eliminating obsolescence risk associated with the 3364W-1-102G. The slightly reduced physical footprint of the TC33X-1-102E is compatible with standard surface mount assembly equipment and does not require PCB redesign for component placement.

Frequently Asked Questions (FAQ)

Q: Can the TC33X-1-102E directly replace the 3364W-1-102G without circuit modification?

A: Yes, for applications where power dissipation does not exceed 0.1W. The electrical characteristics, resistance value, tolerance, temperature coefficient, and adjustment mechanism are identical. Verify that your circuit design does not require the full 0.2W power rating of the original component.

Q: What is the physical compatibility between these two parts?

A: Both components use J lead termination and surface mount mounting type. The TC33X-1-102E has a slightly smaller footprint (0.150" x 0.142" versus 0.177" x 0.150"). Standard surface mount assembly processes accommodate this size difference without requiring PCB layout changes.

Q: Are there compliance or certification differences between the 3364W-1-102G and TC33X-1-102E?

A: No. Both components are ROHS3 compliant, carry MSL rating 1 (unlimited moisture sensitivity), and are REACH unaffected. Regulatory and environmental compliance is equivalent.

Q: Why is the TC33X-1-102E rated at 0.1W instead of 0.2W?

A: The TC33X series represents a newer generation design with improved efficiency characteristics. The lower power rating reflects conservative design specifications for the active production line. Applications with adequate design margin can operate reliably with the reduced rating.

Q: Is the TC33X-1-102E available in the same packaging as the 3364W-1-102G?

A: The TC33X-1-102E is supplied in Tape & Reel (TR) packaging. Verify packaging compatibility with your procurement and assembly requirements.

Q: What should I do if my application requires the full 0.2W power rating?

A: Conduct thermal analysis of your circuit design to determine actual power dissipation at the trimmer potentiometer. If dissipation remains below 0.1W under all operating conditions including temperature extremes, the TC33X-1-102E is suitable. If dissipation exceeds 0.1W, consult Bourns technical documentation for alternative higher-power rated trimmers with matching electrical specifications.
