Key Parameters

Substitute Part Grouping Explanation

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

• Resistance value: 1 kOhms
• Power rating: 0.5W (1/2W)
• Tolerance: ±20%
• Number of turns: 1
• Adjustment type: Side Adjustment
• Physical dimensions: Round - 0.350" Dia x 0.210" H (8.89mm x 5.33mm)
• Termination: PC Pins
• Mounting type: Through Hole
• Series family: Trimpot® 3352 - Open Frame
• Moisture sensitivity level: MSL 1

The substitute part 3352W-1-102LF meets all these parameters identically, differing only in RoHS compliance status. Both parts are manufactured by Bourns Inc. and share the same base product number (3352W), confirming functional and mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

The 3352W-1-102LF serves as a direct functional equivalent to the 3352W-1-102, with the primary distinction being RoHS compliance status. The 3352W-1-102LF achieves ROHS3 compliance, making it the appropriate selection for applications subject to RoHS regulatory requirements or end-market restrictions. The 3352W-1-102 remains suitable for applications where RoHS compliance is not mandated. Both parts maintain identical electrical performance, mechanical fit, and environmental ratings. Selection between these parts should be determined by the specific regulatory and compliance requirements of the target application or end market.

Frequently Asked Questions (FAQ)

Q: Are the 3352W-1-102 and 3352W-1-102LF electrically interchangeable?

A: Yes. Both parts deliver identical electrical performance with 1 kOhms resistance, 0.5W power rating, ±20% tolerance, and single-turn adjustment characteristics.

Q: What is the difference between these two part numbers?

A: The primary difference is RoHS compliance status. The 3352W-1-102LF is ROHS3 compliant, while the 3352W-1-102 is RoHS non-compliant. All other electrical, mechanical, and environmental specifications are identical.

Q: Can I use the 3352W-1-102LF as a drop-in replacement for the 3352W-1-102?

A: Yes. The parts share identical physical dimensions (0.350" Dia x 0.210" H), PC pin termination, through-hole mounting configuration, and all functional parameters. No circuit board modifications or design changes are required.

Q: Which part should I select for new designs?

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

Q: Are both parts currently in production?

A: Yes. Both the 3352W-1-102 and 3352W-1-102LF maintain active product status with Bourns Inc.

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.
