Substitute Part Grouping Explanation

Substitution of the 3352T-1-105 is determined by strict equivalence across all electrical and mechanical parameters: resistance value (1 MOhms), power rating (0.5W), tolerance (±20%), number of turns (1), adjustment type (top adjustment), physical dimensions (0.350" Dia x 0.150" H), termination style (PC Pins), and mounting configuration (through hole). The primary distinction between the main part and its substitute relates to RoHS compliance status. The 3352T-1-105LF variant maintains identical electrical and mechanical specifications while meeting ROHS3 compliance requirements, making it suitable for applications with mandatory RoHS certification.

Parameter Comparison

Engineering Selection Recommendations

Selection between the 3352T-1-105 and 3352T-1-105LF is determined by regulatory and compliance requirements. The 3352T-1-105 is suitable for applications where RoHS compliance is not mandated. The 3352T-1-105LF is the appropriate choice for designs requiring ROHS3 compliance certification. Both parts are active products from Bourns Inc. with unlimited moisture sensitivity rating and identical electrical and mechanical characteristics. The 3352T-1-105LF offers higher current inventory availability (1084 units versus 913 units), which may influence supply chain planning decisions.

Frequently Asked Questions (FAQ)

Q: Are the 3352T-1-105 and 3352T-1-105LF electrically interchangeable?

A: Yes. Both parts have identical resistance (1 MOhms), power rating (0.5W), tolerance (±20%), and number of turns (1). They are direct electrical equivalents.

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

A: The primary difference is RoHS compliance status. The 3352T-1-105 is RoHS non-compliant, while the 3352T-1-105LF meets ROHS3 compliance requirements. All other specifications are identical.

Q: Can I use the 3352T-1-105LF as a drop-in replacement for the 3352T-1-105?

A: Yes. The 3352T-1-105LF is mechanically and electrically identical, with identical dimensions (0.350" Dia x 0.150" H), termination (PC Pins), and mounting type (through hole). It functions as a direct substitute.

Q: Which part should I select for new designs?

A: For new designs, select based on your application's regulatory requirements. If RoHS compliance is required, use the 3352T-1-105LF. If RoHS compliance is not a requirement, either part is acceptable.

Q: Are there any performance differences between these parts?

A: No. Both parts share identical electrical performance characteristics, physical dimensions, and operational specifications. Performance differences do not exist between these variants.

Q: What does the "LF" suffix indicate?

A: The "LF" suffix indicates lead-free termination and RoHS3 compliance. This designation reflects the manufacturing process and material composition used to meet RoHS regulations.
