Substitute Part Grouping Explanation

Substitution for the 3352E-1-104 is determined by strict equivalence across the following critical parameters:

• Resistance value: 100 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

The substitute part 3352E-1-104LF maintains identical electrical and mechanical specifications, with the primary distinction being RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 3352E-1-104 and 3352E-1-104LF are active products from Bourns Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on regulatory and compliance requirements:

The 3352E-1-104LF is ROHS3 compliant, making it the appropriate choice for applications subject to RoHS directives or customer specifications requiring RoHS compliance. The 3352E-1-104 is RoHS non-compliant and should be selected only when RoHS compliance is not a requirement.

Both parts are REACH Affected and carry the same ECCN and HTSUS classifications. Moisture sensitivity level is identical at MSL 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can the 3352E-1-104LF be used as a direct replacement for the 3352E-1-104?

A: Yes. Both parts are electrically and mechanically identical. The 3352E-1-104LF differs only in RoHS compliance status (ROHS3 Compliant versus RoHS non-compliant). Direct substitution is valid when RoHS compliance is acceptable or required.

Q: What does the "LF" suffix in 3352E-1-104LF indicate?

A: The "LF" suffix indicates lead-free construction, which is associated with ROHS3 compliance. This designation reflects the manufacturing process and material composition used to meet RoHS directives.

Q: Are there any dimensional or mounting differences between these parts?

A: No. Both parts share identical physical dimensions (Round - 0.350" Dia x 0.210" H / 8.89mm x 5.33mm) and through-hole PC pin termination. PCB layout and mounting procedures are identical.

Q: Do these parts require different handling or storage procedures?

A: No. Both parts have identical Moisture Sensitivity Level (MSL 1 - Unlimited), indicating no special moisture control requirements during storage or assembly.

Q: Which part should be selected for new designs?

A: Selection depends on design requirements and regulatory environment. For applications subject to RoHS directives or customer RoHS specifications, use 3352E-1-104LF. For applications without RoHS requirements, either part is acceptable based on availability.
