Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3386M-1-201 are qualified based on electrical parameter equivalence across the following criteria:

• Resistance value: 200 Ohms
• Power dissipation: 0.5W (1/2W)
• Tolerance: ±10%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 1 turn
• Adjustment mechanism: Top adjustment
• Resistive element: Cermet composition
• Mounting configuration: Through-hole
• Termination: PC pins

The identified substitutes (25PR200LF and 82PR200LF) satisfy all electrical and functional requirements. Mechanical differences in package size and form factor are noted but do not affect electrical interchangeability when PCB layout accommodates the physical dimensions.

Parameter Comparison

Engineering Selection Recommendations

All three parts satisfy the core electrical requirements for 200 Ohm, 0.5W trimmer potentiometer applications. Selection between the main part and substitutes depends on regulatory and compliance requirements:

The 3386M-1-201 (Bourns Trimpot® 3386 series) is RoHS non-compliant and REACH Affected, making it unsuitable for applications subject to EU environmental regulations or RoHS mandates.

The 25PR200LF (TT Electronics/BI series 25) is RoHS Compliant and REACH Unaffected, providing regulatory alignment for restricted substance directives.

The 82PR200LF (TT Electronics/BI series 82) is ROHS3 Compliant and REACH Unaffected, offering the highest compliance status for current environmental standards.

Physical package differences exist: the 3386M-1-201 features a larger square footprint (9.53mm), while the 25PR200LF uses a smaller square form (6.86mm) and the 82PR200LF employs a round configuration (6.35mm diameter). PCB layout verification is required to confirm mechanical fit.

Frequently Asked Questions (FAQ)

Q: Are the 25PR200LF and 82PR200LF electrically interchangeable with the 3386M-1-201?

A: Yes. All three parts share identical electrical specifications: 200 Ohms resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 1-turn adjustment, top adjustment mechanism, cermet resistive material, through-hole mounting, and PC pin termination. Electrical interchangeability is confirmed.

Q: What are the physical differences between these parts?

A: The 3386M-1-201 has a square footprint of 0.375" x 0.375" (9.53mm x 9.53mm). The 25PR200LF uses a smaller square footprint of 0.270" x 0.270" (6.86mm x 6.86mm). The 82PR200LF employs a round form factor with 0.250" diameter (6.35mm). PCB layout must accommodate the selected package geometry.

Q: Which substitute part should be selected for RoHS-compliant applications?

A: Both the 25PR200LF and 82PR200LF are RoHS Compliant. The 82PR200LF carries ROHS3 Compliant status, representing the most current compliance standard. The 3386M-1-201 is RoHS non-compliant and is not suitable for RoHS-restricted applications.

Q: What is the difference in REACH status between these parts?

A: The 3386M-1-201 is REACH Affected, indicating it may contain substances of concern under EU REACH regulations. Both the 25PR200LF and 82PR200LF are REACH Unaffected, confirming compliance with REACH substance restrictions.

Q: Does packaging type affect electrical performance?

A: No. The 3386M-1-201 and 25PR200LF are supplied in Tube packaging, while the 82PR200LF is supplied in Bulk packaging. Packaging type does not affect electrical characteristics or functional performance; it pertains only to order quantity and handling logistics.

Q: Can the 82PR200LF replace the 3386M-1-201 in existing designs?

A: Electrical replacement is possible due to matching specifications. However, the round form factor (0.250" diameter) differs from the square footprint (0.375" x 0.375") of the 3386M-1-201. PCB layout modification may be required to accommodate the different package geometry. Mechanical fit verification is necessary before implementation.
