Key Parameters

Substitute Part Grouping Explanation

Substitution of the Honeywell 392JB5K is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Resistance value (5k Ohm), power rating (0.5W, 1/2W), and tolerance (±10%)
• Mechanical Configuration: Linear taper, single gang, single turn, 295° rotation, panel mount configuration
• Physical Dimensions: Round body (0.510" diameter), slotted actuator (0.875" length, 0.125" diameter), 1/4-32 bushing thread
• Termination: PC pin termination style
• Adjustment Method: Top adjustment mechanism

The SPRU5021S28 from Precision Electronics Corporation meets all critical electrical and mechanical parameters. The primary difference is the resistive material composition: the 392JB5K uses conductive plastic, while the SPRU5021S28 uses carbon. Both materials deliver equivalent electrical performance within the specified tolerance and power rating for this application category.
