3386W-1-102RLF Trimmer Potentiometer - Equivalent & Substitute Parts

Part Overview

The Bourns 3386W-1-102RLF is a 1 kOhm, 0.5W through-hole trimmer potentiometer with PC pin termination and side adjustment capability. This sealed Trimpot® 3386 series component is designed for precision applications requiring single-turn adjustment in compact form factors. The part maintains Active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified when original inventory is unavailable or when equivalent electrical and mechanical specifications are required for production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3386W-1-102RLF is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Resistance value (1 kOhms), power rating (0.5W), tolerance (±10%), and temperature coefficient (±100ppm/°C) must match exactly
• Mechanical Configuration: Single-turn adjustment with side adjustment mechanism, cermet resistive material, and PC pin termination are non-negotiable
• Physical Form Factor: Square 0.375" x 0.375" face dimension (9.53mm x 9.53mm) ensures PCB layout compatibility
• Regulatory Compliance: RoHS3 compliance and REACH unaffected status maintain design qualification requirements

The TT Electronics/BI 72XR1KLF meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the Bourns 3386W-1-102RLF and TT Electronics/BI 72XR1KLF maintain Active product status with full regulatory compliance. Selection between these parts is based on availability and supply chain requirements rather than technical differentiation. The 72XR1KLF is suitable for direct substitution in applications where the 3386W-1-102RLF is unavailable, provided that design qualification has been completed for the original part number. No additional testing or design modification is required when substituting between these electrically and mechanically equivalent components.

Frequently Asked Questions (FAQ)

Q: Can the 72XR1KLF replace the 3386W-1-102RLF in production?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters. Direct substitution is permissible without design changes.

Q: Are there differences in packaging between these parts?

A: The 3386W-1-102RLF is supplied in Cut Tape (CT) packaging, while the 72XR1KLF is supplied in Bulk packaging. This affects handling and component placement processes but does not impact electrical or mechanical performance.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the 3386W-1-102RLF and 72XR1KLF are ROHS3 compliant and REACH unaffected, meeting identical regulatory standards.

Q: What determines substitution eligibility for this product category?

A: Substitution is determined by exact equivalence in resistance value, power rating, tolerance, temperature coefficient, number of turns, adjustment type, resistive material, mounting type, termination style, and physical dimensions. All parameters must match for direct substitution.

Q: Are there any performance differences between the Bourns and TT Electronics/BI versions?

A: No performance differences exist. Both parts share identical electrical specifications, temperature characteristics, and mechanical form factors.
