Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3352H-1-102 is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Resistance value (1 kOhms), power rating (0.5W), and tolerance (±20%) must be identical
• Mechanical Compatibility: Physical dimensions (0.350" Dia x 0.350" H), adjustment type (side adjustment), and form factor (round) must match exactly
• Termination & Mounting: PC pin termination and through-hole mounting type must be preserved
• Series Consistency: Parts must belong to the Trimpot® 3352 Open Frame series

The identified substitute part maintains all electrical and mechanical parameters while offering improved RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 3352H-1-102 and 3352H-1-102LF are active production parts from Bourns Inc. with identical electrical and mechanical specifications. The primary distinction is RoHS compliance status: the 3352H-1-102LF carries ROHS3 compliance, while the 3352H-1-102 is RoHS non-compliant. Selection between these parts should be based on regulatory requirements applicable to the end application. For designs subject to RoHS directives or customer specifications requiring RoHS compliance, the 3352H-1-102LF is the appropriate choice. Both parts maintain equivalent REACH Affected status and unlimited moisture sensitivity level (MSL 1).

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts are electrically and mechanically identical, with matching resistance (1 kOhms), power rating (0.5W), tolerance (±20%), dimensions (0.350" Dia x 0.350" H), and termination (PC pins through-hole). The LF variant offers improved RoHS compliance.

Q: What does the "LF" suffix indicate in the 3352H-1-102LF part number?

A: The "LF" designation indicates lead-free construction and ROHS3 compliance, distinguishing it from the non-compliant 3352H-1-102 variant.

Q: Are there any differences in performance or reliability between these two parts?

A: No performance or reliability differences exist. Both parts are manufactured by Bourns Inc. within the same Trimpot® 3352 series and maintain identical functional specifications.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory and customer requirements. For applications requiring RoHS compliance, specify the 3352H-1-102LF. Both parts are active in production and equally available.

Q: Do these parts require any special handling or storage considerations?

A: Both parts carry MSL 1 (Unlimited) moisture sensitivity level, indicating no special moisture control requirements during storage or handling.
