Equivalent & Substitute Parts for 3362P-1-202

Part Overview

The Bourns 3362P-1-202 is a 2 kOhms, 0.5W through-hole trimmer potentiometer with PC pin termination, top adjustment, and cermet resistive material. This sealed Trimpot® 3362 series component is designed for applications requiring precision resistance adjustment in compact rectangular form factor. The part is currently active in production. Substitute parts may be required due to inventory availability, packaging preferences, compliance requirements, or mechanical fit considerations in specific PCB layouts.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3362P-1-202 is determined by 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).

The substitute parts identified—3362P-1-202LF, 25PR2KLF, and 72PR2KLF—all satisfy these core electrical and functional requirements. Variations exist in physical dimensions, packaging format, and regulatory compliance status, which are documented in the parameter comparison table below.

Parameter Comparison

Engineering Selection Recommendations

3362P-1-202LF (Bourns Inc.): This direct substitute from Bourns maintains identical electrical specifications and physical dimensions to the 3362P-1-202. The primary distinction is ROHS3 compliance status, making this part suitable for applications requiring RoHS compliance. Packaging remains tube format. This represents the most direct functional equivalent.

25PR2KLF (TT Electronics/BI): This part meets all core electrical and functional requirements with RoHS compliance and REACH unaffected status. The face dimension is square (0.270" x 0.270") rather than rectangular, which may affect PCB layout compatibility. Tube packaging is maintained. Selection of this part requires verification of mechanical fit within the PCB footprint.

72PR2KLF (TT Electronics/BI): This part satisfies all electrical specifications with ROHS3 compliance and REACH unaffected status. The larger square face dimension (0.375" x 0.375") represents a significant mechanical difference from the original part. Bulk packaging is provided instead of tube format. Selection requires confirmation of available PCB space and assembly process compatibility with bulk packaging.

Frequently Asked Questions (FAQ)

Q: Can 3362P-1-202LF be used as a direct replacement for 3362P-1-202?

A: Yes. The 3362P-1-202LF maintains identical electrical specifications (2 kOhms, 0.5W, ±10% tolerance, ±100ppm/°C), physical dimensions (rectangular 0.275" x 0.260"), and termination style (PC pins through hole). The difference is RoHS compliance status. Both are packaged in tube format.

Q: What are the mechanical differences between the substitute parts?

A: The 3362P-1-202 and 3362P-1-202LF share identical rectangular face dimensions (0.275" x 0.260"). The 25PR2KLF has a square face (0.270" x 0.270"), and the 72PR2KLF has a larger square face (0.375" x 0.375"). These dimensional differences may affect PCB footprint compatibility and require layout verification.

Q: Are all substitute parts electrically equivalent?

A: Yes. All substitute parts—3362P-1-202LF, 25PR2KLF, and 72PR2KLF—provide identical electrical performance: 2 kOhms resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 1-turn top adjustment, cermet material, and PC pin termination.

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

A: The 3362P-1-202, 3362P-1-202LF, and 25PR2KLF are supplied in tube packaging. The 72PR2KLF is supplied in bulk packaging, which may require different handling and assembly procedures.

Q: Which substitute part has the best compliance status?

A: The 3362P-1-202LF, 25PR2KLF, and 72PR2KLF all provide RoHS compliance. The 25PR2KLF and 72PR2KLF additionally have REACH unaffected status, whereas the 3362P-1-202LF maintains REACH affected status. Selection depends on specific regulatory requirements for the application.

Q: Can I use 72PR2KLF if my PCB has limited space?

A: The 72PR2KLF has a larger face dimension (0.375" x 0.375") compared to the original 3362P-1-202 (0.275" x 0.260"). PCB layout verification is required to confirm available space before selection.
