Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 51CAD-E28-A13 is determined by strict equivalence across the following critical parameters:

• Resistance value: 5k Ohm
• Power rating: 1W
• Taper characteristic: Linear
• Resistive material: Cermet
• Termination: PC Pins
• Mounting configuration: Panel Mount
• Rotation angle: 290°
• Bushing thread specification: 1/4-32
• Temperature coefficient: ±150ppm/°C
• Sealed construction

The substitute part 51CAD-E28-A13L maintains identical electrical and mechanical specifications to the main part, with the primary distinction being product status and regulatory compliance classification.

Parameter Comparison

Engineering Selection Recommendations

The 51CAD-E28-A13L serves as the direct active equivalent to the obsolete 51CAD-E28-A13. Both components are manufactured by Bourns Inc. within the Pro Audio 51 series and share identical electrical and mechanical specifications across all functional parameters.

The primary distinction between these parts is regulatory and availability status. The 51CAD-E28-A13L is classified as an active product with ROHS3 compliance and REACH affected status, whereas the original 51CAD-E28-A13 is obsolete and RoHS non-compliant. For new designs or component replacement in systems requiring current regulatory compliance, the 51CAD-E28-A13L is the appropriate selection. Both parts are functionally interchangeable in applications requiring a 5k Ohm, 1W cermet linear potentiometer with panel mount configuration and PC pin termination.

Frequently Asked Questions (FAQ)

Q: Are the 51CAD-E28-A13 and 51CAD-E28-A13L electrically identical?
