Bourns 3352P-1-102 Thumbwheel Potentiometer Equivalent & Substitute Parts

Part Overview

The Bourns 3352P-1-102 is a 1 kOhms, 0.5W through-hole thumbwheel potentiometer with top adjustment, part of the Trimpot® 3352 Open Frame series. This component is actively manufactured and widely used in applications requiring manual resistance adjustment with a compact form factor. Finding equivalent or substitute parts becomes necessary when addressing RoHS compliance requirements, managing inventory across supply chains, or accommodating design revisions that specify alternative part variants.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 3352P-1-102 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must match:

• 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 0.210" H (8.89mm x 5.33mm)
• Termination style: PC Pins
• Mounting configuration: Through Hole
• Series classification: Trimpot® 3352 - Open Frame

The primary distinction between the main part and its substitute relates to RoHS compliance status and inventory availability, not functional or mechanical characteristics.

Engineering Selection Recommendations

The 3352P-1-102LF serves as a direct functional substitute for the 3352P-1-102, with identical electrical and mechanical specifications. Selection between these parts should be based on compliance requirements and supply chain considerations:

• Use 3352P-1-102LF when ROHS3 compliance is mandated by design specifications or regulatory requirements.
• Use 3352P-1-102 when RoHS compliance is not a constraint and the non-compliant variant is acceptable for the application.
• Both parts are actively manufactured and maintain equivalent performance characteristics across all specified parameters.
• Inventory levels indicate higher availability of the 3352P-1-102LF variant (1475 Pcs vs. 970 Pcs).

Frequently Asked Questions (FAQ)

Q: Are the 3352P-1-102 and 3352P-1-102LF electrically identical?

A: Yes. Both parts have identical resistance (1 kOhms), power rating (0.5W), tolerance (±20%), and all other electrical specifications. The difference is RoHS compliance status only.

Q: Can I substitute 3352P-1-102LF for 3352P-1-102 in existing designs?

A: Yes, provided your design does not explicitly prohibit ROHS3-compliant components. All mechanical and electrical parameters are equivalent, and both use identical PC pin termination and through-hole mounting.

Q: What does the "LF" suffix in 3352P-1-102LF indicate?

A: The "LF" designation indicates lead-free construction, which is associated with ROHS3 compliance. This is the primary distinction between the two part numbers.

Q: Are there any dimensional differences between these parts?

A: No. Both parts share identical physical dimensions: Round - 0.350" Dia x 0.210" H (8.89mm x 5.33mm). PCB layout and mechanical mounting are interchangeable.

Q: Which part should I specify for new designs?

A: Specify 3352P-1-102LF for new designs unless RoHS exemption is explicitly required. This ensures compliance with current regulatory standards and provides better long-term supply chain stability.
