Bourns 3329P-1-202 Trimmer Potentiometer - Equivalent & Substitute Parts

Part Overview

The Bourns 3329P-1-202 is a 2 kOhms, 0.5W through-hole trimmer potentiometer with PC pin termination, top adjustment, and cermet resistive material. This component is classified as Active product status. Substitute parts are identified when inventory constraints, compliance requirements, or manufacturing discontinuation necessitate alternative sourcing while maintaining electrical and mechanical compatibility within the specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3329P-1-202 are qualified based on matching the following critical parameters: resistance value (2 kOhms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), number of turns (1), adjustment type (top adjustment), resistive material (cermet), mounting type (through hole), and termination style (PC pins). Parts meeting these electrical and mechanical criteria are classified as direct or similar substitutes. Variations in physical dimensions, RoHS compliance status, and manufacturer identity do not disqualify substitution eligibility when all functional parameters align.

Parameter Comparison

Engineering Selection Recommendations

The 3329P-1-202LF (Bourns) is a direct substitute offering identical electrical specifications and the same Trimpot® 3329 series platform. This variant provides ROHS3 compliance, addressing regulatory requirements where the original 3329P-1-202 does not. Both parts maintain REACH Affected status and EAR99 export classification.

The 25PR2KLF (TT Electronics/BI) is a similar substitute meeting all electrical and mechanical functional parameters. This part offers RoHS compliance and REACH Unaffected status, providing alternative compliance positioning. Physical dimensions differ (square 0.270" x 0.270" face versus round 0.250" diameter), requiring verification of PCB layout compatibility before implementation.

Selection between substitutes depends on compliance requirements, inventory availability, and mechanical fit constraints within the target application.

Frequently Asked Questions (FAQ)

Q: Can the 3329P-1-202LF replace the 3329P-1-202 in existing designs?

A: Yes. The 3329P-1-202LF maintains identical electrical specifications (2 kOhms, 0.5W, ±10% tolerance, ±100ppm/°C temperature coefficient) and mechanical configuration (through-hole PC pins, top adjustment, cermet material, 1 turn). The primary difference is RoHS3 compliance status. No circuit redesign is required.

Q: What are the physical dimension differences between substitutes?

A: The 3329P-1-202 and 3329P-1-202LF both feature round geometry at 0.250" diameter (6.35mm). The 25PR2KLF features square geometry at 0.270" x 0.270" face (6.86mm x 6.86mm). PCB footprint compatibility must be verified before substitution.

Q: Are there compliance differences between the three parts?

A: Yes. The 3329P-1-202 is RoHS non-compliant and REACH Affected. The 3329P-1-202LF is ROHS3 Compliant and REACH Affected. The 25PR2KLF is RoHS Compliant and REACH Unaffected. Selection depends on target market regulatory requirements.

Q: Do all three parts share the same ECCN and HTSUS classification?

A: Yes. All three parts are classified as ECCN EAR99 and HTSUS 8533.40.8050, maintaining consistent export and tariff treatment.

Q: What inventory levels are available for each part?

A: 3329P-1-202: 803 pcs. 3329P-1-202LF: 2326 pcs. 25PR2KLF: 5508 pcs.
