Key Parameters

Substitute Part Grouping Explanation

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

• Resistance value: 1 kOhms
• Power rating: 0.5W (1/2W)
• Tolerance: ±10%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 1
• Adjustment type: Side Adjustment
• Resistive material: Cermet
• Mounting type: Through Hole
• Termination style: PC Pins
• Physical dimensions: Square - 0.375" x 0.375" (9.53mm x 9.53mm)

The TT Electronics/BI 72XR1KLF meets all electrical and mechanical parameters required for direct substitution. Packaging format differs (Bulk vs. Tube), and regulatory compliance status varies, but functional performance and board-level compatibility remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both the 3386V-1-102 and 72XR1KLF are active products with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

Regulatory Compliance: The 72XR1KLF is ROHS3 compliant and REACH unaffected, while the 3386V-1-102 is RoHS non-compliant and REACH affected. Applications subject to RoHS or REACH regulations should specify the 72XR1KLF.

Packaging Requirements: The 3386V-1-102 is supplied in Tube packaging (1080 units available), while the 72XR1KLF is supplied in Bulk packaging (2606 units available). Tube packaging is preferred for automated assembly processes; Bulk packaging is suitable for manual assembly or reel-based handling.

Supply Availability: The 72XR1KLF offers higher current inventory (2606 units) compared to the 3386V-1-102 (1080 units), making it the preferred choice for high-volume production schedules.

Frequently Asked Questions (FAQ)

Q: Can the 72XR1KLF directly replace the 3386V-1-102 on a PCB?

A: Yes. Both parts are electrically and mechanically identical. They share the same resistance value, power rating, tolerance, temperature coefficient, adjustment type, resistive material, mounting type, termination style, and physical dimensions. No circuit modifications or board redesign is required.

Q: What is the difference between Tube and Bulk packaging?

A: Tube packaging contains components in a protective tube suitable for automated pick-and-place equipment and reel feeding. Bulk packaging supplies loose components in larger quantities, typically used for manual assembly or custom reel preparation. Both packaging formats contain identical components.

Q: Why does the 3386V-1-102 show RoHS non-compliant status while the 72XR1KLF is ROHS3 compliant?

A: RoHS compliance status reflects the manufacturing process and material composition at the time of production. The 72XR1KLF meets current RoHS3 directives, making it suitable for applications in regulated markets. The 3386V-1-102 may be used in applications where RoHS compliance is not required.

Q: Are there any performance differences between these two trimmer potentiometers?

A: No. Both parts deliver identical performance across all specified electrical parameters: 1 kOhm resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 1-turn adjustment, cermet resistive element, and side adjustment mechanism.

Q: Which part should be selected for new designs?

A: For new designs subject to RoHS or REACH regulations, the 72XR1KLF is the appropriate choice. For applications without regulatory constraints, either part is functionally equivalent. Supply chain considerations and packaging requirements should guide the final selection.
