Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3386Y-1-201 are qualified based on the following electrical and mechanical parameters:

• Resistance value: 200 Ohms (exact match required)
• Power rating: 0.5W minimum
• Tolerance: ±10% (matching specification)
• Temperature coefficient: ±100ppm/°C (matching specification)
• Number of turns: 1 (single-turn operation)
• Adjustment type: Top Adjustment (functional equivalence)
• Resistive material: Cermet (material class equivalence)
• Mounting type: Through Hole (PCB integration method)
• Termination style: PC Pins (electrical connection method)

The identified substitutes—25PR200LF and 82PR200LF—meet all core electrical parameters. Physical dimensions vary (square vs. round form factors), which may affect PCB layout compatibility but does not impact electrical function or performance within the specified operating range.

Parameter Comparison

Engineering Selection Recommendations

All three parts—3386Y-1-201, 25PR200LF, and 82PR200LF—are active products with identical electrical specifications and are functionally equivalent for circuit applications requiring 200 Ohm, 0.5W, single-turn trimmer potentiometers with cermet construction.

The 25PR200LF and 82PR200LF offer compliance advantages: both are RoHS Compliant (or ROHS3 Compliant) and REACH Unaffected, compared to the 3386Y-1-201 which is RoHS non-compliant and REACH Affected. Selection between substitutes should account for PCB layout constraints due to form factor differences (square vs. round) and packaging requirements (Tube vs. Bulk).

Frequently Asked Questions (FAQ)

Q: Can 25PR200LF or 82PR200LF be used as direct replacements for 3386Y-1-201?

A: Yes. All three parts share identical electrical specifications: 200 Ohms, 0.5W, ±10% tolerance, ±100ppm/°C temperature coefficient, 1-turn operation, top adjustment, cermet material, through-hole mounting, and PC pin termination. Substitution is electrically valid. Physical dimensions differ, requiring PCB layout verification.

Q: What are the physical differences between these parts?

A: The 3386Y-1-201 has a square form factor (0.375" x 0.375" face). The 25PR200LF is also square but smaller (0.270" x 0.270" face). The 82PR200LF is round (0.250" diameter). These differences may affect PCB footprint compatibility and board space allocation.

Q: Are there compliance differences between these parts?

A: Yes. The 25PR200LF and 82PR200LF are RoHS Compliant and REACH Unaffected. The 3386Y-1-201 is RoHS non-compliant and REACH Affected. For applications requiring regulatory compliance, the TT Electronics/BI alternatives are preferred.

Q: What packaging options are available?

A: The 3386Y-1-201 and 25PR200LF are supplied in Tube packaging. The 82PR200LF is supplied in Bulk packaging. Packaging selection depends on procurement volume and handling requirements.

Q: Do all parts have the same adjustment mechanism?

A: Yes. All three parts feature top adjustment with single-turn operation, enabling identical tuning and calibration procedures in circuit applications.
