Substitute Part Grouping Explanation

Substitution eligibility for the 3352E-1-105 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must match:

• Resistance value: 1 MOhms
• Power rating: 0.5W (1/2W)
• Tolerance: ±20%
• Number of turns: 1
• Adjustment type: Top 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
• Moisture sensitivity: MSL 1 (Unlimited)

The identified substitute part 3352E-1-105LF meets all these criteria and is manufactured by Bourns Inc., ensuring functional and mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

The 3352E-1-105LF serves as a direct functional substitute for the 3352E-1-105. Both parts are active products from Bourns Inc. and are electrically and mechanically identical across all specified parameters.

The primary distinction is regulatory compliance: the 3352E-1-105LF carries ROHS3 compliance, while the 3352E-1-105 is RoHS non-compliant. Selection between these parts should be based on applicable regulatory requirements in the target application and manufacturing region. Both parts maintain identical REACH Affected status and ECCN classification.

Frequently Asked Questions (FAQ)

Q: Can the 3352E-1-105LF be used as a direct replacement for the 3352E-1-105?

A: Yes. Both parts are electrically and mechanically identical. The 3352E-1-105LF is functionally interchangeable in all circuit applications where the 3352E-1-105 is specified.

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

A: The primary difference is RoHS compliance status. The 3352E-1-105LF is ROHS3 compliant, while the 3352E-1-105 is RoHS non-compliant. All other electrical, mechanical, and regulatory parameters are identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical dimensions: Round - 0.350" Dia x 0.210" H (8.89mm x 5.33mm). They are mechanically interchangeable in PCB layouts and mechanical assemblies.

Q: Do these parts have the same termination style?

A: Yes. Both parts use PC Pins termination and are configured for through-hole mounting.

Q: Which part should I select for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS compliance, specify the 3352E-1-105LF. For applications without RoHS requirements, either part is acceptable based on availability and procurement considerations.

Q: Are there any differences in moisture sensitivity?

A: No. Both parts have identical Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no moisture sensitivity constraints.
