Bourns 3362M-1-102 Trimmer Potentiometer: Equivalent & Substitute Parts

Part Overview

The Bourns 3362M-1-102 is a 1 kOhm, 0.5W through-hole trimmer potentiometer with PC pin termination and side adjustment capability. This sealed Trimpot® 3362 series component is designed for applications requiring precision resistance adjustment in compact form factors. The part is currently active in production with 934 units in stock. Substitute parts are identified when original inventory is unavailable, when RoHS3 compliance is required, or when alternative packaging or mechanical configurations better suit specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3362M-1-102 is determined by strict equivalence across the following critical parameters: resistance value (1 kOhms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), number of turns (1), adjustment type (side adjustment), resistive material (cermet), mounting type (through hole), and termination style (PC pins).

Two substitute parts meet these criteria:

Direct Equivalent (3362M-1-102LF): Identical electrical and mechanical specifications within the same Bourns Trimpot® 3362 series. Differs only in RoHS compliance status (ROHS3 compliant versus non-compliant) and packaging format (tube).

Similar Equivalent (72XR1KLF): Manufactured by TT Electronics/BI, this part maintains all critical electrical parameters and mechanical compatibility. Differences include manufacturer series designation (72 versus 3362), physical face dimensions (0.375" x 0.375" square versus 0.275" x 0.260" rectangular), packaging format (bulk versus tube), and REACH compliance status.

Parameter Comparison

Engineering Selection Recommendations

3362M-1-102LF is the preferred direct substitute when RoHS3 compliance is mandated or when REACH-affected material restrictions apply to the original 3362M-1-102. Both parts are manufactured by Bourns within the same sealed Trimpot® 3362 series, ensuring mechanical and electrical interchangeability. Identical face dimensions and PC pin configuration allow direct board-level substitution without layout modification.

72XR1KLF serves as a functional equivalent when the larger 0.375" x 0.375" square form factor is acceptable within the application's mechanical constraints. This TT Electronics/BI alternative provides REACH-unaffected status and higher inventory availability (2606 units). The increased physical dimensions require PCB layout verification to confirm clearance compatibility. Bulk packaging may be advantageous for high-volume production runs.

Selection between 3362M-1-102LF and 72XR1KLF depends on compliance requirements, available board space, and packaging volume needs. Both maintain full electrical equivalence across all specified parameters.

Frequently Asked Questions (FAQ)

Q: Can 3362M-1-102LF be used as a direct replacement for 3362M-1-102?

A: Yes. Both parts are electrically and mechanically identical within the Bourns Trimpot® 3362 series. The primary difference is RoHS3 compliance status. Direct board-level substitution is possible without design modification.

Q: What are the mechanical compatibility considerations for 72XR1KLF?

A: The 72XR1KLF has a larger square face dimension (0.375" x 0.375") compared to the rectangular 3362M-1-102 (0.275" x 0.260"). PCB layout must accommodate this increased footprint. PC pin termination and through-hole mounting remain compatible.

Q: Are all three parts electrically equivalent?

A: Yes. All three parts share identical resistance (1 kOhms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), number of turns (1), adjustment type (side adjustment), resistive material (cermet), mounting type (through hole), and termination style (PC pins).

Q: Which substitute should be selected for RoHS3-compliant applications?

A: Both 3362M-1-102LF and 72XR1KLF are ROHS3 compliant. Choose 3362M-1-102LF for identical form factor and Bourns series continuity. Choose 72XR1KLF if REACH-unaffected status is required or if the larger footprint is acceptable.

Q: What is the difference in packaging between these parts?

A: 3362M-1-102 and 3362M-1-102LF are supplied in tube packaging. 72XR1KLF is supplied in bulk packaging, which may be more suitable for high-volume manufacturing operations.

Q: Can 72XR1KLF be used in applications with space constraints?

A: The larger square footprint (0.375" x 0.375") of 72XR1KLF may not fit in designs optimized for the smaller rectangular form factor (0.275" x 0.260"). PCB layout verification is required before selection.
