Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3362R-1-202 is determined by the following core 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). All identified substitutes match these electrical and functional specifications. Physical dimensions vary across substitute options, which may affect PCB layout compatibility and mechanical fit. Packaging format differences (tube versus bulk) do not affect electrical performance.

Parameter Comparison

Engineering Selection Recommendations

The 3362R-1-202LF is the direct equivalent from Bourns Inc., offering identical electrical specifications and physical dimensions with ROHS3 compliance. This part is the preferred substitute when RoHS compliance is required and PCB layout accommodates the rectangular 0.275" x 0.260" footprint.

The 25PR2KLF, 72PR2KLF, and 82PR2KLF are functionally equivalent alternatives from TT Electronics/BI. All three match the core electrical parameters and support the same through-hole PC pin termination. Selection among these alternatives depends on available PCB space and mechanical constraints:

The 25PR2KLF maintains a compact square footprint (0.270" x 0.270") comparable to the original part and carries RoHS compliance.

The 72PR2KLF provides a larger square footprint (0.375" x 0.375") and ROHS3 compliance, suitable for applications with less stringent space requirements.

The 82PR2KLF offers a round form factor (0.250" diameter) with ROHS3 compliance, applicable to designs where circular geometry is preferred or required.

All substitute parts are active products with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can 3362R-1-202LF replace 3362R-1-202 directly?

A: Yes. The 3362R-1-202LF is electrically and mechanically identical to the 3362R-1-202, with the primary difference being ROHS3 compliance. Both parts share the same rectangular footprint (0.275" x 0.260"), resistance value (2 kOhms), power rating (0.5W), and PC pin termination. Direct PCB substitution is supported without layout modification.

Q: What are the physical dimension differences among substitute parts?

A: The 3362R-1-202 and 3362R-1-202LF share a rectangular footprint of 0.275" x 0.260" (6.99mm x 6.60mm). The 25PR2KLF uses a square footprint of 0.270" x 0.270" (6.86mm x 6.86mm). The 72PR2KLF uses a larger square footprint of 0.375" x 0.375" (9.53mm x 9.53mm). The 82PR2KLF uses a round form factor with 0.250" diameter (6.35mm). PCB layout verification is required when substituting parts with different physical dimensions.

Q: Are all substitute parts functionally equivalent in electrical performance?

A: Yes. All listed substitute parts match the core electrical specifications: 2 kOhms resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 1 turn, top adjustment, cermet resistive material, through-hole mounting, and PC pin termination. Electrical performance is equivalent across all options.

Q: What is the difference between tube and bulk packaging?

A: The 3362R-1-202 and 3362R-1-202LF are supplied in tube packaging. The 72PR2KLF and 82PR2KLF are supplied in bulk packaging. The 25PR2KLF is supplied in tube packaging. Packaging format does not affect component electrical or mechanical specifications. Selection depends on procurement quantity requirements and handling procedures.

Q: Which substitute part offers the best RoHS compliance?

A: The 3362R-1-202LF, 72PR2KLF, and 82PR2KLF all carry ROHS3 compliance. The 25PR2KLF carries RoHS compliance. The original 3362R-1-202 is RoHS non-compliant. For applications requiring RoHS3 certification, the 3362R-1-202LF is the direct Bourns equivalent, while 72PR2KLF and 82PR2KLF are TT Electronics/BI alternatives.
