Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3386U-1-202A is determined by strict equivalence across 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). All substitute parts listed meet these electrical and functional requirements. Physical dimensions and packaging formats may vary, which affects mechanical fit and procurement logistics but does not alter electrical performance within the specified parameter range.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts are Active status components with identical electrical specifications. Selection between the 3386U-1-202A and its substitutes depends on compliance and regulatory requirements:

The 3386U-1-202A is RoHS non-compliant and REACH Affected. Applications requiring RoHS compliance must use 25PR2KLF, 72PR2KLF, or 82PR2KLF, all of which are RoHS3 Compliant and REACH Unaffected.

For applications with no RoHS or REACH restrictions, the 3386U-1-202A remains a valid selection. Physical dimensions differ across substitutes: the 25PR2KLF features a smaller square footprint (0.270" x 0.270"), the 72PR2KLF matches the original square footprint (0.375" x 0.375"), and the 82PR2KLF uses a round form factor (0.250" diameter). PCB layout and mechanical clearance requirements determine which form factor is appropriate.

Frequently Asked Questions (FAQ)

Q: Can 25PR2KLF, 72PR2KLF, and 82PR2KLF be used interchangeably with 3386U-1-202A?

A: Yes, from an electrical standpoint. All parts share identical resistance (2 kOhms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), adjustment type (top), and termination style (PC pins). Physical dimensions and packaging differ, requiring verification of PCB layout compatibility and mechanical fit.

Q: What is the primary difference between these substitute parts?

A: The main differences are physical form factor and compliance status. The 25PR2KLF has a smaller square body (0.270" x 0.270"), the 72PR2KLF maintains the original square size (0.375" x 0.375"), and the 82PR2KLF uses a round body (0.250" diameter). All TT Electronics/BI parts are RoHS3 Compliant and REACH Unaffected, while the original 3386U-1-202A is RoHS non-compliant and REACH Affected.

Q: Which substitute should I select for a RoHS-compliant application?

A: Any of the three TT Electronics/BI substitutes (25PR2KLF, 72PR2KLF, or 82PR2KLF) meet RoHS3 compliance. Choose based on available PCB space: use 25PR2KLF for compact layouts, 72PR2KLF for standard spacing, or 82PR2KLF if a round form factor is preferred.

Q: Does packaging format affect electrical performance?

A: No. Packaging (Tape & Box, Tube, or Bulk) affects procurement and handling logistics but does not alter electrical characteristics or performance.

Q: Are there any restrictions on using these parts interchangeably?

A: Mechanical fit must be verified. The different physical dimensions require confirmation that the selected substitute fits the PCB footprint and mechanical clearance requirements of the application. Electrical performance is equivalent across all listed parts.
