Key Parameters

Substitute Part Grouping Explanation

Substitution of the 3352W-1-104 is determined by strict equivalence across the following critical parameters:

• Resistance value: 100 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 style: PC Pins
• Mounting configuration: Through Hole
• Series classification: Trimpot® 3352 - Open Frame

The substitute part 3352W-1-104LF maintains identical electrical and mechanical specifications while differing in RoHS compliance status. Both parts are manufactured by Bourns Inc. and share the same base product number (3352W).

Parameter Comparison

Engineering Selection Recommendations

Both the 3352W-1-104 and 3352W-1-104LF are functionally equivalent components with identical electrical and mechanical characteristics. Selection between these parts should be based on regulatory and compliance requirements:

The 3352W-1-104LF variant is ROHS3 compliant, making it the appropriate choice for applications subject to RoHS (Restriction of Hazardous Substances) regulations. The 3352W-1-104 is RoHS non-compliant and should be selected only when RoHS compliance is not a requirement.

Both parts are REACH Affected and carry the same ECCN (EAR99) and HTSUS (8533.40.8050) classifications. Both maintain unlimited moisture sensitivity tolerance (MSL 1).

Frequently Asked Questions (FAQ)

Q: Are the 3352W-1-104 and 3352W-1-104LF electrically interchangeable?

A: Yes. Both parts have identical resistance (100 kOhms), power rating (0.5W), tolerance (±20%), and all electrical specifications. They can be substituted without affecting circuit performance.

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

A: The primary difference is RoHS compliance status. The 3352W-1-104LF is ROHS3 compliant, while the 3352W-1-104 is not. Both parts are otherwise identical in electrical and mechanical specifications.

Q: Can I use the 3352W-1-104 in place of the 3352W-1-104LF?

A: Electrically and mechanically, yes. However, if your application or end-market requires RoHS compliance, the 3352W-1-104LF must be used instead.

Q: Are the physical dimensions identical?

A: Yes. Both parts are Round - 0.350" Dia x 0.210" H (8.89mm x 5.33mm) with identical PC Pin termination and through-hole mounting configuration.

Q: What does the "LF" suffix in 3352W-1-104LF indicate?

A: The "LF" suffix indicates lead-free construction, which is associated with ROHS3 compliance.

Q: Are both parts available in bulk packaging?

A: Yes. Both the 3352W-1-104 (994 Pcs) and 3352W-1-104LF (1138 Pcs) are available as new original stock in bulk packaging.
