Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3386C-1-501 is determined by strict equivalence across the following critical parameters:

• Resistance value: 500 Ohms
• 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 family: Trimpot® 3386 - Sealed

The 3386C-1-501LF qualifies as a direct substitute because it maintains identical electrical and mechanical specifications while offering improved compliance status.

Parameter Comparison

Engineering Selection Recommendations

The 3386C-1-501LF is a direct functional equivalent to the 3386C-1-501 with identical electrical performance and mechanical compatibility. Selection between these parts should be based on regulatory and compliance requirements:

• Use 3386C-1-501LF for designs requiring RoHS3 compliance or REACH compliance
• Use 3386C-1-501 only when legacy non-compliant specifications are explicitly required
• Both parts are active products with established supply chains
• Inventory availability: 3386C-1-501 (5150 units), 3386C-1-501LF (2900 units)

Frequently Asked Questions (FAQ)

Q: Can the 3386C-1-501LF be used as a direct replacement for the 3386C-1-501?

A: Yes. The 3386C-1-501LF is electrically and mechanically identical to the 3386C-1-501. All functional parameters—resistance, power rating, tolerance, temperature coefficient, adjustment type, and physical dimensions—are equivalent. The primary difference is compliance status.

Q: What is the difference between these two parts?

A: The 3386C-1-501LF is RoHS3 compliant and REACH unaffected, while the 3386C-1-501 is RoHS non-compliant and REACH affected. Electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns when substituting these parts?

A: No. Both parts use identical PC pin termination, through-hole mounting, and physical dimensions (0.375" x 0.375"). They are pin-for-pin and footprint-compatible.

Q: Which part should I specify for new designs?

A: Specify the 3386C-1-501LF for new designs to ensure compliance with current RoHS3 and REACH regulations.

Q: What is the packaging format for both parts?

A: Both parts are supplied in tube packaging.
