Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3329S-1-202 is determined by matching the following critical parameters:

• Resistance value: 2 kOhms
• Power rating: 0.5W
• Tolerance: ±10%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 1
• Adjustment type: Side Adjustment
• Resistive material: Cermet
• Mounting type: Through Hole
• Termination style: PC Pins
• Physical dimensions: Rectangular - 0.260" x 0.330" Face (6.60mm x 8.38mm)
• Series: Trimpot® 3329 - Sealed
• Manufacturer: Bourns Inc.

The 3329S-1-202LF qualifies as a direct substitute because it maintains identical electrical and mechanical specifications while differing only in packaging format and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

The 3329S-1-202LF serves as a direct functional equivalent to the 3329S-1-202. Selection between these parts should be based on the following criteria:

Choose 3329S-1-202LF when:

• RoHS3 compliance is required for the end application or supply chain
• Tube packaging is preferred for automated assembly or inventory management
• Lead-free termination is mandated by design specifications

Choose 3329S-1-202 when:

• RoHS compliance is not a requirement
• Standard packaging meets assembly and storage needs
• Existing inventory or supply agreements specify the non-compliant variant

Both parts are active products from Bourns Inc. and maintain identical electrical performance, mechanical fit, and functional characteristics within the Trimpot® 3329 sealed series.

Frequently Asked Questions (FAQ)

Q: Can the 3329S-1-202LF replace the 3329S-1-202 in existing designs?

A: Yes. The 3329S-1-202LF is electrically and mechanically identical to the 3329S-1-202. Both parts have the same resistance value, power rating, tolerance, temperature coefficient, adjustment type, and physical dimensions. The primary differences are packaging format and RoHS compliance status.

Q: What is the difference between the standard packaging and tube packaging?

A: The 3329S-1-202 uses standard packaging, while the 3329S-1-202LF is supplied in tube packaging. Tube packaging is commonly used for automated pick-and-place assembly operations and provides different handling and storage characteristics.

Q: Does RoHS3 compliance affect electrical performance?

A: No. RoHS3 compliance relates to material composition and environmental restrictions, not electrical specifications. Both the RoHS-compliant 3329S-1-202LF and the non-compliant 3329S-1-202 deliver identical electrical performance.

Q: Are there any dimensional differences between these parts?

A: No. Both parts share the same rectangular form factor of 0.260" x 0.330" face (6.60mm x 8.38mm) and are mechanically interchangeable.

Q: What does the "LF" suffix in 3329S-1-202LF indicate?

A: The "LF" suffix typically indicates lead-free termination and RoHS compliance in Bourns part numbering conventions.
