Substitute Part Grouping Explanation

The 3352W-1-502LF qualifies as a direct substitute based on matching all critical electrical and mechanical parameters: identical 5 kOhms resistance, 0.5W power rating, ±20% tolerance, single-turn adjustment, side adjustment configuration, and through-hole PC pin termination. Both parts share the same physical dimensions (0.350" Dia x 0.210" H) and belong to the same Trimpot® 3352 Open Frame series.

The primary distinction between these parts is RoHS compliance status. The substitution logic is based on the following key parameters:

• Resistance value
• Power rating
• Tolerance specification
• Adjustment type and configuration
• Physical dimensions
• Termination style
• Mounting method

Parameter Comparison

Engineering Selection Recommendations

The 3352W-1-502LF is a direct functional equivalent to the 3352W-1-502. Both parts are active products from Bourns Inc. with identical electrical and mechanical specifications. The 3352W-1-502LF offers ROHS3 compliance, whereas the 3352W-1-502 is RoHS non-compliant. Selection between these parts should be based on regulatory and compliance requirements applicable to the end application. Both parts maintain the same MSL rating, ECCN classification, and HTSUS code.

Frequently Asked Questions (FAQ)

Q: Can the 3352W-1-502LF be used as a direct replacement for the 3352W-1-502?

A: Yes. Both parts share identical electrical specifications (5 kOhms, 0.5W, ±20% tolerance), mechanical dimensions (0.350" Dia x 0.210" H), adjustment type (side adjustment), and termination style (PC pins through-hole). They are functionally interchangeable in circuit applications.

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

A: The primary difference is RoHS compliance status. The 3352W-1-502LF is ROHS3 compliant, while the 3352W-1-502 is RoHS non-compliant. All other specifications, including resistance, power rating, tolerance, physical dimensions, and mounting configuration, are identical.

Q: Are there any packaging differences between these parts?

A: Both parts are supplied in bulk packaging. No packaging format differences are specified in the technical data.

Q: Which part should I select for new designs?

A: Selection depends on compliance requirements. For applications requiring RoHS3 compliance, use the 3352W-1-502LF. For applications without RoHS compliance mandates, either part is suitable based on availability and cost considerations.

Q: Do these parts have the same moisture sensitivity level?

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