Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3352E-1-102 are identified based on strict equivalence across the following critical parameters:

• Resistance value: 1 kOhms
• 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 family: Trimpot® 3352 - Open Frame

The 3352E-1-102LF variant meets all these criteria and is classified as a direct manufacturer substitute. The primary distinction between the main part and its substitute relates to RoHS compliance status and lead-free termination processing.

Parameter Comparison

Engineering Selection Recommendations

Both the 3352E-1-102 and 3352E-1-102LF are active production components from Bourns Inc. with identical electrical and mechanical specifications. Selection between these parts depends on regulatory and compliance requirements:

The 3352E-1-102 is suitable for applications where RoHS compliance is not mandated or where legacy component specifications are required.

The 3352E-1-102LF is the appropriate choice for designs requiring ROHS3 compliance. This variant incorporates lead-free termination processing while maintaining all functional and dimensional equivalence to the standard version.

Both parts are REACH Affected and classified under ECCN EAR99 with HTSUS code 8533.40.8050.

Frequently Asked Questions (FAQ)

Q: Can the 3352E-1-102LF be used as a direct replacement for the 3352E-1-102?

A: Yes. The 3352E-1-102LF is a direct functional equivalent. All electrical parameters (resistance, power rating, tolerance, number of turns), mechanical dimensions, termination style, and mounting configuration are identical. The primary difference is RoHS compliance status and lead-free processing.

Q: What is the significance of the "LF" suffix in the part number 3352E-1-102LF?

A: The "LF" designation indicates lead-free termination processing and ROHS3 compliance. This variant meets regulatory requirements for applications in regions or industries mandating RoHS compliance.

Q: Are there any performance differences between the 3352E-1-102 and 3352E-1-102LF?

A: No. Both parts deliver identical performance across all specified electrical and mechanical parameters. The substitution is functionally transparent at the circuit level.

Q: What mounting considerations apply to both variants?

A: Both parts are through-hole mounted components with PC pin termination. They share identical physical dimensions (0.350" diameter x 0.210" height) and are suitable for standard PCB through-hole assembly processes.

Q: Which part should be selected for new designs?

A: For new designs, the 3352E-1-102LF is the recommended choice due to ROHS3 compliance, which aligns with current regulatory standards and supply chain practices. The 3352E-1-102 remains available for legacy or non-regulated applications.
