Substitute Part Grouping Explanation

Substitute parts for the 3386X-1-504 are identified based on electrical and mechanical parameter equivalence within the Bourns Trimpot® 3386 sealed series. Substitution criteria include:

• Identical resistance value: 500 kOhms
• Identical power rating: 0.5W
• Identical tolerance: ±10%
• Identical temperature coefficient: ±100ppm/°C
• Identical number of turns: 1
• Identical adjustment type: Side Adjustment
• Identical resistive material: Cermet
• Identical mounting type: Through Hole
• Identical termination style: PC Pins
• Identical physical dimensions: Square - 0.375" x 0.375" (9.53mm x 9.53mm)
• Same base product number: 3386X

The 3386X-1-504LF variant meets all electrical and mechanical equivalence criteria and is classified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the 3386X-1-504 and 3386X-1-504LF are active production parts with identical electrical and mechanical specifications. Selection between these parts should be based on regulatory and compliance requirements:

The 3386X-1-504LF is recommended for applications requiring RoHS3 compliance and REACH unaffected status. This variant is suitable for designs targeting modern regulatory environments and supply chains with strict environmental compliance mandates.

The 3386X-1-504 remains suitable for applications where RoHS non-compliance and REACH affected status are acceptable within the design and procurement framework.

Both parts share identical functional performance characteristics and are mechanically and electrically interchangeable within the same circuit design.

Frequently Asked Questions (FAQ)

Q: Are the 3386X-1-504 and 3386X-1-504LF electrically identical?

A: Yes. Both parts have identical resistance value (500 kOhms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), and all other electrical specifications. They are functionally equivalent in circuit operation.

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

A: The primary difference is regulatory compliance status. The 3386X-1-504LF is ROHS3 compliant and REACH unaffected, while the 3386X-1-504 is RoHS non-compliant and REACH affected. Both parts are mechanically and physically identical.

Q: Can I substitute the 3386X-1-504LF for the 3386X-1-504 in an existing design?

A: Yes. The parts are mechanically and electrically interchangeable. The 3386X-1-504LF can be used as a direct substitute without circuit modifications or design changes.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical square form factor dimensions of 0.375" x 0.375" (9.53mm x 9.53mm) and identical through-hole PC pin termination. They are pin-compatible and footprint-compatible.

Q: Which part should I select for new designs?

A: Selection depends on regulatory requirements. For designs requiring RoHS3 and REACH compliance, use the 3386X-1-504LF. Both parts are active in production and available for procurement.
