Bourns 3299X-1-201 Trimmer Potentiometer: Equivalent & Substitute Parts

Part Overview

The Bourns 3299X-1-201 is a 200 Ohm, 0.5W through-hole trimmer potentiometer with PC pin termination and side adjustment. This sealed Trimpot® 3299 series component features cermet resistive material and 25-turn adjustment capability, designed for precision tuning applications in electronic circuits. The part is currently active in production. Substitute parts may be required due to inventory availability, compliance requirements, or specific application constraints such as RoHS certification needs or dimensional specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3299X-1-201 are qualified based on the following electrical and mechanical parameters:

Core Substitution Criteria:

• Resistance value: 200 Ohms
• Power rating: 0.5W (1/2W)
• Tolerance: ±10%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 25
• Adjustment type: Side Adjustment
• Resistive material: Cermet
• Mounting type: Through Hole
• Termination style: PC Pins
• Manufacturer: Bourns Inc.

Two substitute parts meet these criteria:

1. 3296X-1-201 – Differs only in face dimension (0.395" x 0.190" vs. 0.395" x 0.240") and belongs to the Trimpot® 3296 series. All electrical parameters and core mechanical specifications are identical.

2. 3299X-1-201LF – Identical to the main part in all electrical and mechanical parameters. Differs in RoHS compliance status (ROHS3 Compliant vs. RoHS non-compliant).

Parameter Comparison

Engineering Selection Recommendations

3299X-1-201LF is the preferred substitute when RoHS3 compliance is required. This part is electrically and mechanically identical to the main part 3299X-1-201 and maintains the same face dimensions, ensuring direct compatibility in existing PCB layouts and mechanical assemblies.

3296X-1-201 is suitable as a substitute only when the reduced face dimension (0.395" x 0.190" vs. 0.395" x 0.240") is compatible with the application's mechanical constraints. All electrical parameters remain identical. This part is RoHS non-compliant, matching the compliance status of the main part.

Selection between substitutes depends on two factors: compliance requirements (RoHS3 vs. non-compliant) and available PCB space for the component's face dimension.

Frequently Asked Questions (FAQ)

Q: Can 3296X-1-201 be used as a direct replacement for 3299X-1-201?

A: The 3296X-1-201 is electrically equivalent but has a smaller face dimension (0.190" vs. 0.240" height). It is mechanically compatible only if the PCB layout accommodates the reduced dimension. All electrical specifications are identical.

Q: What is the difference between 3299X-1-201 and 3299X-1-201LF?

A: The parts are electrically and mechanically identical. The primary difference is RoHS compliance: 3299X-1-201LF is ROHS3 Compliant, while 3299X-1-201 is RoHS non-compliant. Select 3299X-1-201LF for applications requiring RoHS certification.

Q: Are all three parts from the same manufacturer?

A: Yes, all three parts are manufactured by Bourns Inc. The 3299X-1-201 and 3299X-1-201LF belong to the Trimpot® 3299 series, while 3296X-1-201 belongs to the Trimpot® 3296 series.

Q: Do the substitute parts have the same PC pin termination?

A: Yes, all three parts feature PC pin termination and through-hole mounting, ensuring compatibility with standard PCB assembly processes.

Q: What packaging is used for these parts?

A: All three parts are supplied in tube packaging.
