Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3386R-1-201 are grouped based on electrical parameter equivalence and mechanical compatibility. All identified substitutes maintain the following core parameters:

• Resistance value: 200 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

Substitutes are classified as Direct (identical electrical and mechanical specifications) or Similar (equivalent electrical specifications with dimensional variations).

Parameter Comparison

Engineering Selection Recommendations

Direct Substitute (Identical Specifications): The 3386R-1-201LF is a direct substitute for the 3386R-1-201. Both parts are manufactured by Bourns Inc. and share identical electrical and mechanical specifications. The primary difference is RoHS compliance status: the 3386R-1-201LF is ROHS3 Compliant, while the original 3386R-1-201 is RoHS non-compliant. Selection of the 3386R-1-201LF is appropriate for applications requiring RoHS compliance.

Similar Substitutes (Equivalent Electrical Specifications with Dimensional Variations): The 25PR200LF and 82PR200LF are manufactured by TT Electronics/BI and maintain all electrical specifications identical to the main part. Both are RoHS Compliant. These parts differ in physical dimensions and packaging format:

• 25PR200LF: Square form factor (0.270" x 0.270"), smaller than the original, supplied in Tube packaging
• 82PR200LF: Round form factor (0.250" Dia), supplied in Bulk packaging

Selection between these similar substitutes depends on available PCB space and mechanical mounting constraints. The smaller footprints of 25PR200LF and 82PR200LF may be advantageous in space-constrained designs.

Frequently Asked Questions (FAQ)

Q: Can the 3386R-1-201LF be used as a direct replacement for the 3386R-1-201? A: Yes. The 3386R-1-201LF is electrically and mechanically identical to the 3386R-1-201. The LF suffix indicates lead-free termination and RoHS3 compliance. No circuit modifications are required.

Q: What are the key differences between the 25PR200LF and 82PR200LF substitutes? A: Both maintain identical electrical specifications (200 Ω, 0.5W, ±10% tolerance, ±100ppm/°C). The primary differences are physical form factor and packaging: 25PR200LF is square (0.270" x 0.270") in Tube packaging, while 82PR200LF is round (0.250" Dia) in Bulk packaging.

Q: Are all substitute parts RoHS compliant? A: The 3386R-1-201LF, 25PR200LF, and 82PR200LF are all RoHS compliant. The original 3386R-1-201 is RoHS non-compliant.

Q: Can I use a smaller form factor substitute if my PCB has space constraints? A: Yes, provided the through-hole PC pin termination and top adjustment access are compatible with your PCB layout. The 25PR200LF and 82PR200LF have smaller footprints than the original 3386R-1-201.

Q: What is the difference between Tube and Bulk packaging? A: Tube packaging (3386R-1-201, 3386R-1-201LF, 25PR200LF) is typically used for smaller order quantities and component protection. Bulk packaging (82PR200LF) is used for larger volume orders. Packaging does not affect electrical or mechanical performance.
