Key Parameters

Substitute Part Grouping Explanation

The 3352P-1-502LF is classified as a direct manufacturer substitute based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Resistance value: 5 kOhms (exact match)
• Power rating: 0.5W / 1/2W (exact match)
• Tolerance: ±20% (exact match)
• Number of turns: 1 (exact match)
• Adjustment type: Top Adjustment (exact match)
• Physical dimensions: Round - 0.350" Dia x 0.210" H (exact match)
• Termination style: PC Pins (exact match)
• Mounting method: Through Hole (exact match)
• Series classification: Trimpot® 3352 - Open Frame (exact match)
• Moisture sensitivity: MSL 1 (exact match)

The primary distinction between the main part and substitute is RoHS compliance status and current inventory levels.

Parameter Comparison

Engineering Selection Recommendations

Both the 3352P-1-502 and 3352P-1-502LF are active production parts from Bourns Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on regulatory compliance requirements and supply chain considerations.

The 3352P-1-502LF offers ROHS3 compliance, making it suitable for applications subject to RoHS directives. The 3352P-1-502 remains available for applications where RoHS compliance is not a requirement. Both parts maintain REACH affected status and identical MSL ratings.

Inventory availability favors the 3352P-1-502LF with 1203 units in stock compared to 768 units for the 3352P-1-502.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical resistance value (5 kOhms), power rating (0.5W), tolerance (±20%), adjustment type (top adjustment), physical dimensions (0.350" Dia x 0.210" H), termination style (PC Pins), and mounting method (through hole). They are functionally and mechanically interchangeable.

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

A: The primary difference is RoHS compliance status. The 3352P-1-502LF is ROHS3 compliant, while the 3352P-1-502 is RoHS non-compliant. Both parts are REACH affected and carry identical MSL ratings.

Q: Which part should I select for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS compliance, specify the 3352P-1-502LF. For applications without RoHS requirements, either part is acceptable based on availability and supply chain considerations.

Q: Are there any differences in packaging or termination?

A: No. Both parts use identical PC Pin termination, through-hole mounting, and bulk packaging. Physical dimensions and mounting footprints are identical.

Q: What is the MSL rating for these parts?

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