Bourns 3386H-1-104 Trimmer Potentiometer Equivalent & Substitute Parts

Part Overview

The Bourns 3386H-1-104 is a 100 kOhms, 0.5W through-hole trimmer potentiometer with PC pin termination and side adjustment capability. This sealed Trimpot® 3386 series component is designed for applications requiring precision resistance adjustment in compact form factors. The part is currently active in production. Equivalent and substitute parts may be required due to RoHS compliance requirements, supply chain considerations, or specific regulatory compliance needs for end applications.

Substitute Part Grouping Explanation

Substitution for the 3386H-1-104 is based on electrical and mechanical parameter equivalence within the Trimpot® 3386 sealed series. The substitute part 3386H-1-104LF maintains identical electrical specifications: 100 kOhms resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 1-turn side adjustment, cermet resistive material, through-hole mounting, and PC pin termination. Physical dimensions remain unchanged at 0.375" x 0.375" face size.

The primary distinction between these parts is regulatory compliance status. The 3386H-1-104LF variant incorporates RoHS3 compliance and REACH unaffected status, whereas the base 3386H-1-104 is RoHS non-compliant and REACH affected. Both parts share the same ECCN (EAR99) and HTSUS classification (8533.40.8050).

Parameter Comparison

Engineering Selection Recommendations

The 3386H-1-104LF is the preferred substitute when RoHS3 compliance is required for end-product certification or regulatory market access. Applications subject to RoHS3 directives or requiring REACH unaffected component status should specify the 3386H-1-104LF variant.

The 3386H-1-104 remains suitable for applications without RoHS compliance mandates or where legacy component specifications are acceptable. Both parts are active production items from Bourns Inc. and maintain identical electrical and mechanical performance characteristics.

Selection between these variants should be driven by end-product regulatory requirements and supply chain availability rather than functional performance considerations.

Frequently Asked Questions (FAQ)

Q: Are the 3386H-1-104 and 3386H-1-104LF electrically interchangeable?

A: Yes. Both parts provide identical electrical performance: 100 kOhms resistance, 0.5W power rating, ±10% tolerance, and ±100ppm/°C temperature coefficient. They are functionally equivalent in circuit operation.

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

A: The primary difference is regulatory compliance. The 3386H-1-104LF is RoHS3 compliant and REACH unaffected, while the 3386H-1-104 is RoHS non-compliant and REACH affected. All electrical and mechanical specifications are identical.

Q: Can I use 3386H-1-104LF as a direct replacement for 3386H-1-104?

A: Yes. The 3386H-1-104LF is a direct mechanical and electrical substitute. It occupies the same PCB footprint, uses identical PC pin termination, and maintains the same 0.375" x 0.375" form factor.

Q: Which part should I specify for new designs?

A: Specify 3386H-1-104LF for new designs requiring RoHS3 compliance or REACH unaffected status. This ensures regulatory compliance for current and future market requirements.

Q: Are there any performance differences between these parts?

A: No. Both parts are manufactured from identical materials (cermet resistive element), use the same sealed Trimpot® 3386 series construction, and deliver equivalent performance across all electrical parameters.

Q: What is the packaging format for both parts?

A: Both the 3386H-1-104 and 3386H-1-104LF are supplied in tube packaging for through-hole component handling and storage.
