62PR100LF Equivalent & Substitute Parts

Part Overview

The 62PR100LF is a 100 Ohm, 0.5W through-hole trimmer potentiometer manufactured by TT Electronics/BI. This cermet-based component features PC pin termination and top adjustment capability with a 1.0 turn configuration. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing maintenance, repair, and legacy system support. Substitute parts must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement without circuit redesign.

Substitute Part Grouping Explanation

Substitute parts for the 62PR100LF are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

• 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 (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)
• Physical size: Round - 0.250" Dia / 6.35mm (exact match required)

The 3329P-1-101LF from Bourns Inc. meets all specified parameters and qualifies as a direct substitute.
