Bourns 3366P-1-101 Trimmer Potentiometer Equivalent & Substitute Parts

Part Overview

The Bourns 3366P-1-101 is a 100 Ohm, 0.5W through-hole trimmer potentiometer with PC pin termination and top adjustment. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity. The 3366 series represents an earlier generation of sealed trimmer potentiometers that has been superseded by the active 3362 series within the Bourns Trimpot® product line.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 3366P-1-101 is based on electrical and mechanical parameter matching across the following criteria:

• Resistance value: 100 Ohms (exact match required)
• Power rating: 0.5W / 1/2W (exact match required)
• Tolerance: ±10% (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Number of turns: 1 Turn (exact match required)
• Adjustment type: Top Adjustment (exact match required)
• Resistive material: Cermet (exact match required)
• Mounting type: Through Hole (exact match required)
• Termination style: PC Pins (exact match required)

The Bourns 3362P-1-101 meets all electrical specifications and mechanical interface requirements. Minor dimensional variation in the face geometry (rectangular 0.275" x 0.260" versus square 0.276" x 0.276") remains within acceptable tolerance for standard PCB footprint compatibility in through-hole applications.

Parameter Comparison

Engineering Selection Recommendations

The 3362P-1-101 is the direct functional equivalent for the obsolete 3366P-1-101. Selection of the 3362P-1-101 is based on:

• Active product status ensuring long-term availability and supply chain continuity
• Identical electrical performance across all critical parameters (resistance, power rating, tolerance, temperature coefficient)
• Equivalent mechanical interface (through-hole PC pin termination with compatible footprint dimensions)
• Sealed design classification consistent with the original 3366 series heritage
• Manufacturer-recommended substitution designation

The minor dimensional difference in face geometry does not impact PCB layout compatibility for standard through-hole applications. Verification of PCB footprint clearance is recommended for designs with tight spatial constraints.

Frequently Asked Questions (FAQ)

Q: Can the 3362P-1-101 be used as a direct replacement for the 3366P-1-101 in existing designs?

A: Yes. The 3362P-1-101 provides identical electrical specifications and compatible mechanical interface. The face dimension difference (rectangular versus square) is within acceptable tolerance for standard through-hole PCB layouts.

Q: What is the primary reason for substitution?

A: The 3366P-1-101 is classified as obsolete. The 3362P-1-101 is the active equivalent within the Bourns Trimpot® product line, ensuring continued availability and supply chain support.

Q: Are there compliance differences between the two parts?

A: The 3366P-1-101 is REACH Unaffected. The 3362P-1-101 is REACH Affected. Both parts carry EAR99 ECCN classification and identical HTSUS codes. RoHS compliance status differs: the 3366P-1-101 status is not specified; the 3362P-1-101 is RoHS non-compliant.

Q: What packaging is available for the substitute part?

A: The 3362P-1-101 is supplied in Tube packaging. Confirm packaging requirements with your procurement specification.

Q: Are the PC pin terminations identical?

A: Yes. Both parts use PC pin termination style suitable for through-hole PCB mounting. Pin spacing and engagement characteristics are compatible.

Q: What is the tolerance specification for both parts?

A: Both the 3366P-1-101 and 3362P-1-101 carry ±10% tolerance on the 100 Ohm resistance value.
