• Power Rating: 0.5W (1/2W)
• Tolerance: ±10%
• Temperature Coefficient: ±100ppm/°C
• Number of Turns: 1
• Resistive Material: Cermet

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole
• Termination Style: PC Pins

Allowed Variations:

• Adjustment Type: Top or Side adjustment
• Physical Size/Dimension: Variations permitted within package compatibility constraints
• Packaging Format: Tube or Bulk
• Manufacturer: Different manufacturers acceptable

All substitute parts listed maintain identical electrical specifications and core mechanical compatibility while allowing for dimensional and adjustment type variations.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain full electrical equivalence to the 3386G-1-102LF with identical resistance, power rating, tolerance, and temperature coefficient specifications. Selection among substitutes is determined by application-specific requirements:

Direct Mechanical Equivalents (Identical Footprint):

• 72PR1KLF and 72PMR1KLF: Square 0.375" x 0.375" form factor matches the main part. Both are ROHS3 compliant. Selection between these depends on packaging requirements (Bulk vs. Tube availability).

Compact Form Factor Alternative:

• 25PR1KLF: Smaller square footprint (0.270" x 0.270") for space-constrained applications. RoHS compliant. Top adjustment maintained.

Circular Form Factor Alternative:

• 82PR1KLF: Round 0.250" diameter package for applications requiring circular geometry. ROHS3 compliant. Top adjustment maintained.

Side Adjustment Alternative:

• M63P102KB40: Larger square footprint (0.395" x 0.395") with side adjustment instead of top adjustment. ROHS3 compliant. Use only when side adjustment is functionally required and PCB layout accommodates larger dimensions.

All parts carry Active product status and meet ROHS3 or RoHS compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 3386G-1-102LF with any of these parts directly?

A: All listed parts are electrically equivalent with matching 1 kOhm resistance, 0.5W power rating, ±10% tolerance, and ±100ppm/°C temperature coefficient. Substitution is valid provided the PCB layout accommodates the physical dimensions and adjustment type of the selected alternative.

Q: What is the difference between top adjustment and side adjustment?

A: Top adjustment (3386G-1-102LF, 25PR1KLF, 72PR1KLF, 72PMR1KLF, 82PR1KLF) allows potentiometer tuning from the top surface of the component. Side adjustment (M63P102KB40) requires access from the side. Selection depends on PCB layout and accessibility requirements during assembly and field adjustment.

Q: Are there dimensional constraints I should consider?

A: Yes. The main part is 0.375" x 0.375" square. The 25PR1KLF is smaller (0.270" x 0.270"), the 82PR1KLF is circular (0.250" diameter), and the M63P102KB40 is larger (0.395" x 0.395"). Verify PCB footprint compatibility before selection.

Q: What is the difference between Tube and Bulk packaging?

A: Tube packaging (3386G-1-102LF, 25PR1KLF) is used for smaller quantities and provides component protection during handling. Bulk packaging (72PR1KLF, 72PMR1KLF, 82PR1KLF, M63P102KB40) is used for larger volume orders. Electrical and mechanical specifications are identical; packaging choice depends on order quantity and inventory management requirements.

Q: Are all parts RoHS compliant?

A: Yes. The main part (3386G-1-102LF) and all substitutes (25PR1KLF, 72PR1KLF, 72PMR1KLF, 82PR1KLF, M63P102KB40) are RoHS compliant. The main part and most substitutes are ROHS3 compliant; 25PR1KLF is RoHS compliant.

Q: Can I use 72PR1KLF and 72PMR1KLF interchangeably?

A: Both parts have identical electrical specifications and physical dimensions (0.375" x 0.375" square). The difference is packaging format: 72PR1KLF is supplied in Bulk, while 72PMR1KLF is also Bulk. Both are ROHS3 compliant and functionally equivalent. Selection depends on inventory and supply chain requirements.
