Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3352T-1-502 is determined by matching the following critical parameters:

• Resistance value: 5 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
• Termination type: PC Pins
• Mounting configuration: Through Hole
• Series classification: Trimpot® 3352 - Open Frame

Parts meeting all these criteria are functionally equivalent and may be used as direct replacements. Variations in RoHS compliance status do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the 3352T-1-502 and 3352T-1-502LF are active production components from Bourns Inc. with identical electrical and mechanical specifications. Selection between these parts is determined by regulatory compliance requirements:

The 3352T-1-502LF carries ROHS3 compliance certification, making it the appropriate choice for applications subject to RoHS directives or customer specifications requiring lead-free termination compliance. The 3352T-1-502 remains available for applications without RoHS compliance mandates. Both parts maintain REACH Affected status and identical moisture sensitivity ratings.

Frequently Asked Questions (FAQ)

Q: Can the 3352T-1-502LF replace the 3352T-1-502 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The primary difference is RoHS compliance status. Substitution is valid provided the application does not require RoHS non-compliant components.

Q: What does the "LF" suffix indicate in the 3352T-1-502LF part number?

A: The "LF" designation indicates lead-free termination and ROHS3 compliance. This reflects the manufacturing process and material composition of the termination pins.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical dimensions: Round - 0.350" Dia x 0.150" H (8.89mm x 3.81mm). PCB footprints and mounting requirements are interchangeable.

Q: Do these parts have different moisture sensitivity levels?

A: No. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS compliance, specify the 3352T-1-502LF. For applications without RoHS mandates, either part is acceptable based on availability and cost considerations.
