• Tolerance: ±10%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 1
• Adjustment type: Top Adjustment
• Resistive material: Cermet
• Mounting type: Through Hole
• Termination style: PC Pins
• Physical dimensions: Square - 0.375" x 0.375" face

The substitute part 3386P-1-253LF maintains identical electrical and mechanical specifications, with the primary distinction being RoHS compliance status and REACH classification.

Parameter Comparison

Engineering Selection Recommendations

Both the 3386P-1-253 and 3386P-1-253LF are functionally equivalent for applications requiring 25 kOhm, 0.5W trimmer potentiometers with identical electrical performance and physical form factors.

The 3386P-1-253LF is the preferred selection for applications subject to RoHS3 compliance requirements or REACH-restricted substance regulations. The "LF" designation indicates lead-free termination and RoHS3 compliance.

The 3386P-1-253 remains suitable for applications without RoHS or REACH compliance mandates, where REACH-affected materials are acceptable.

Both parts share identical ECCN and HTSUS classifications, ensuring consistent export control and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Are the 3386P-1-253 and 3386P-1-253LF electrically interchangeable?

A: Yes. Both parts have identical resistance (25 kOhms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), and all other electrical specifications. They are direct functional equivalents.

Q: What does the "LF" suffix indicate?

A: The "LF" suffix denotes lead-free termination and RoHS3 compliance. The 3386P-1-253LF meets RoHS3 requirements, while the 3386P-1-253 does not.

Q: Can I use the 3386P-1-253LF as a drop-in replacement for the 3386P-1-253?
