Equivalent & Substitute Parts for 3386K-1-102

Part Overview

The Bourns 3386K-1-102 is a 1 kOhms, 0.5W through-hole trimmer potentiometer with cermet resistive material, top adjustment, and PC pin termination. This component is classified as Active product status. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility parameters are maintained across alternative manufacturers and series designations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following critical parameters: resistance value (1 kOhms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), number of turns (1), resistive material (Cermet), mounting type (Through Hole), and termination style (PC Pins).

Substitute parts are grouped into two categories:

Category A: Top Adjustment Configuration — Parts maintaining identical adjustment type (top adjustment) with equivalent electrical and mechanical specifications. These include 25PR1KLF, 72PMR1KLF, and 72PR1KLF from TT Electronics/BI.

Category B: Alternative Adjustment Configuration — Part M63P102KB40 from Vishay Spectrol maintains all electrical parameters and through-hole PC pin termination but features side adjustment instead of top adjustment. This represents a functional alternative where adjustment access differs.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Top Adjustment, Identical Footprint): Parts 72PMR1KLF and 72PR1KLF maintain the same square 0.375" x 0.375" footprint as the 3386K-1-102 with top adjustment configuration. Both are ROHS3 Compliant and REACH Unaffected, offering improved regulatory compliance compared to the main part.

Compact Alternative (Top Adjustment, Reduced Footprint): Part 25PR1KLF provides top adjustment functionality in a smaller square 0.270" x 0.270" footprint. This option is suitable for space-constrained applications and is RoHS Compliant with REACH Unaffected status.

Compact Alternative (Top Adjustment, Circular Footprint): Part 82PR1KLF offers top adjustment in a round 0.250" diameter configuration, providing a different form factor while maintaining electrical equivalence. ROHS3 Compliant and REACH Unaffected.

Alternative Adjustment Access (Side Adjustment): Part M63P102KB40 from Vishay Spectrol maintains all electrical specifications and PC pin termination but features side adjustment instead of top adjustment. The square 0.395" x 0.395" footprint is slightly larger. ROHS3 Compliant with MSL 1 rating.

Frequently Asked Questions (FAQ)

Q: Can 25PR1KLF replace 3386K-1-102 in a PCB layout? A: Electrical substitution is valid. However, the 25PR1KLF has a smaller footprint (0.270" x 0.270" versus 0.375" x 0.375"), requiring PCB layout verification to confirm pad spacing compatibility.

Q: What is the difference between 72PMR1KLF and 72PR1KLF? A: Both parts are electrically and mechanically equivalent with identical footprints and adjustment type. The primary difference is packaging: 72PMR1KLF is supplied in Bulk, while 72PR1KLF is also supplied in Bulk. Inventory levels differ (2034 Pcs versus 1900 Pcs).

Q: Is M63P102KB40 a direct replacement for 3386K-1-102? A: Electrical parameters are equivalent. The adjustment type differs (side versus top), and the footprint is slightly larger (0.395" x 0.395"). PCB layout and mechanical clearance must be verified before substitution.

Q: Why are some substitutes ROHS3 Compliant while the main part is RoHS non-compliant? A: RoHS compliance status reflects manufacturing standards at the time of production. Substitute parts from TT Electronics/BI and Vishay Spectrol meet current ROHS3 requirements, offering improved regulatory alignment for new designs.

Q: Can 82PR1KLF be used if space is limited? A: Yes, the round 0.250" diameter footprint provides the most compact option. Verify that the circular form factor is compatible with your PCB layout and mechanical assembly requirements.

Q: Are all substitute parts in active production? A: All listed substitute parts maintain Active product status, confirming ongoing availability and manufacturer support.
