Substitute Part Grouping Explanation

Substitution of the 3352T-1-104 is determined by strict equivalence across all electrical and mechanical parameters. The allowed substitution criteria are:

• Identical resistance value: 100 kOhms
• Identical power rating: 0.5W (1/2W)
• Identical tolerance: ±20%
• Identical number of turns: 1
• Identical adjustment type: Top Adjustment
• Identical physical dimensions: Round - 0.350" Dia x 0.150" H (8.89mm x 3.81mm)
• Identical termination: PC Pins
• Identical mounting type: Through Hole
• Identical series: Trimpot® 3352 - Open Frame
• Identical MSL rating: 1 (Unlimited)

The 3352T-1-104LF meets all these criteria and is classified as a direct substitute. The primary distinction is the RoHS compliance status and inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The 3352T-1-104LF is a direct functional equivalent to the 3352T-1-104. Both parts are active products from Bourns Inc. with identical electrical and mechanical specifications. The 3352T-1-104LF offers ROHS3 compliance, whereas the main part is RoHS non-compliant. For applications requiring RoHS compliance, the 3352T-1-104LF is the appropriate selection. The 3352T-1-104LF also provides significantly higher inventory availability (20,818 pcs vs. 724 pcs), supporting supply chain continuity. Both parts are REACH affected and carry the same ECCN and HTSUS classifications.

Frequently Asked Questions (FAQ)

Q: Can the 3352T-1-104LF be used as a direct replacement for the 3352T-1-104?

A: Yes. The 3352T-1-104LF is electrically and mechanically identical to the 3352T-1-104. All functional parameters—resistance, power rating, tolerance, adjustment type, physical dimensions, termination, and mounting configuration—are equivalent. PCB layout and mechanical mounting require no modification.

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

A: The primary difference is RoHS compliance status. The 3352T-1-104LF is ROHS3 compliant, while the 3352T-1-104 is RoHS non-compliant. Both parts are REACH affected. The 3352T-1-104LF also has higher inventory availability.

Q: Are there any performance differences between these parts?

A: No. Both parts operate identically within the specified 100 kOhms resistance, 0.5W power rating, and ±20% tolerance. Electrical performance, adjustment resolution, and mechanical durability are equivalent.

Q: Which part should be selected for new designs?

A: For new designs, the 3352T-1-104LF is recommended due to ROHS3 compliance and superior inventory availability. For legacy designs currently using the 3352T-1-104, substitution to the 3352T-1-104LF requires no design changes.

Q: Are both parts available in the same packaging?

A: Yes. Both parts are supplied in bulk packaging as specified by Bourns Inc.
