Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3352T-1-102 is determined by strict equivalence across the following parameters:

• Resistance value: 1 kOhms
• Power rating: 0.5W (1/2W)
• Tolerance: ±20%
• Number of turns: 1
• Adjustment type: Top Adjustment
• Physical dimensions: Round - 0.350" Dia x 0.150" H (8.89mm x 3.81mm)
• Termination style: PC Pins
• Mounting configuration: Through Hole
• Base product series: Trimpot® 3352 - Open Frame

Parts meeting all these criteria are classified as direct equivalents. Variations in RoHS compliance status or lead-free termination do not affect functional or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the 3352T-1-102 and 3352T-1-102LF are functionally and mechanically equivalent. Selection between these parts is determined by regulatory and compliance requirements:

The 3352T-1-102LF variant is ROHS3 compliant, making it the appropriate choice for applications subject to RoHS3 regulations. The 3352T-1-102 is RoHS non-compliant and suitable for applications without RoHS compliance mandates. Both parts carry REACH Affected status and EAR99 export classification.

Inventory availability differs between variants, with the 3352T-1-102LF offering higher stock levels (1646 units versus 845 units).

Frequently Asked Questions (FAQ)

Q: Can the 3352T-1-102LF be used as a direct replacement for the 3352T-1-102?

A: Yes. Both parts are electrically and mechanically identical. The "LF" suffix indicates lead-free termination and ROHS3 compliance. Functional performance, resistance value, power rating, physical dimensions, and mounting configuration are identical.

Q: What does the "LF" designation mean?

A: LF indicates lead-free termination and ROHS3 compliance status. This affects material composition of the solder connection points but does not alter electrical or mechanical specifications.

Q: Are there any dimensional differences between these parts?

A: No. Both parts share identical physical dimensions: Round - 0.350" Dia x 0.150" H (8.89mm x 3.81mm). PCB footprint and mounting hole spacing are identical.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS3 compliance, use 3352T-1-102LF. For applications without RoHS compliance mandates, either part is acceptable based on availability and cost considerations.

Q: Do these parts have identical electrical performance?

A: Yes. Both parts have 1 kOhms resistance, ±20% tolerance, 0.5W power rating, 1 turn adjustment, and top adjustment configuration. Electrical behavior is identical.
