Substitute Part Grouping Explanation

Substitution eligibility for the 3386F-1-101 is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match identically for a part to function as a direct substitute:

• Resistance value: 100 Ohms
• Power rating: 0.5W (1/2W)
• 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" (9.53mm x 9.53mm)
• Series: Trimpot® 3386 - Sealed

The 3386F-1-101LF meets all these criteria and is classified as a direct manufacturer equivalent. Differences in RoHS and REACH compliance status do not affect electrical or mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both the 3386F-1-101 and 3386F-1-101LF are electrically and mechanically identical. Selection between these parts should be based on regulatory and compliance requirements applicable to the end application.

The 3386F-1-101LF is the preferred choice for applications subject to RoHS3 compliance mandates or REACH-restricted substance regulations. The 3386F-1-101 remains suitable for applications without such compliance constraints. Both parts maintain identical electrical performance, tolerance specifications, and physical form factor, ensuring direct interchangeability in circuit design and PCB layout.

Frequently Asked Questions (FAQ)

Q: Can the 3386F-1-101LF be used as a direct replacement for the 3386F-1-101?

A: Yes. The 3386F-1-101LF is electrically and mechanically identical to the 3386F-1-101. All critical parameters including resistance, power rating, tolerance, temperature coefficient, adjustment type, and physical dimensions are equivalent. The parts are directly interchangeable in circuit applications.

Q: What is the difference between the 3386F-1-101 and 3386F-1-101LF?

A: The primary differences are regulatory compliance designations. The 3386F-1-101LF is RoHS3 compliant and REACH unaffected, while the 3386F-1-101 is RoHS non-compliant and REACH affected. Electrical and mechanical specifications are identical.

Q: Which part should I select for a new design?

A: Selection depends on your application's regulatory requirements. For designs requiring RoHS3 compliance or REACH compliance, specify the 3386F-1-101LF. For applications without these compliance mandates, either part is acceptable based on availability and cost considerations.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share the same square form factor of 0.375" x 0.375" (9.53mm x 9.53mm) and identical PC pin termination, ensuring compatibility with existing PCB layouts and through-hole mounting patterns.

Q: What is the packaging format for these parts?

A: Both the 3386F-1-101 and 3386F-1-101LF are supplied in tube packaging.
