Substitute Part Grouping Explanation

Substitution eligibility for the 3386C-1-253 is determined by strict equivalence across the following parameters:

• Resistance value: 25 kOhms
• Power rating: 0.5W (1/2W)
• Tolerance: ±10%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 1
• Adjustment type: Side Adjustment
• Resistive material: Cermet
• Mounting type: Through Hole
• Termination style: PC Pins
• Physical dimensions: Square - 0.375" x 0.375" (9.53mm x 9.53mm)
• Series: Trimpot® 3386 - Sealed

The 3386C-1-253LF qualifies as a direct substitute based on identical electrical and mechanical specifications. Differences in RoHS and REACH compliance status do not affect functional interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both the 3386C-1-253 and 3386C-1-253LF are Active status components with identical electrical and mechanical specifications. Selection between these parts should be based on regulatory compliance requirements:

• Use 3386C-1-253LF for applications requiring ROHS3 compliance and REACH unaffected status.
• Use 3386C-1-253 where RoHS non-compliance and REACH affected status are acceptable.

Both parts are functionally interchangeable in circuit design and PCB layout. No design modifications are required when substituting between these part numbers.

Frequently Asked Questions (FAQ)

Q: Are the 3386C-1-253 and 3386C-1-253LF electrically identical?

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

Q: Can I substitute 3386C-1-253LF for 3386C-1-253 on an existing PCB?

A: Yes. The parts are mechanically and electrically equivalent. No PCB layout changes are required. Pin configuration, footprint, and mounting type are identical.

Q: What is the difference between these two part numbers?

A: The primary differences are RoHS and REACH compliance status. The 3386C-1-253LF is ROHS3 compliant and REACH unaffected, while the 3386C-1-253 is RoHS non-compliant and REACH affected. Functional performance is identical.

Q: Which part should I specify for new designs?

A: Selection depends on your application's regulatory requirements. For applications requiring RoHS3 compliance, specify 3386C-1-253LF. Both parts are Active status and available from inventory.

Q: Are there any performance differences in temperature stability or tolerance?

A: No. Both parts share identical temperature coefficient (±100ppm/°C) and tolerance (±10%). Performance across operating temperature ranges is equivalent.
