Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 51CAD-E24-A15 is determined by strict equivalence across the following critical parameters: resistance value (10k Ohm), power rating (1W), taper characteristic (Linear), resistive material composition (Cermet), termination method (PC Pins), mounting configuration (Panel Mount), number of gangs (1), number of turns (1.0), rotation angle (290°), tolerance (±10%), temperature coefficient (±150ppm/°C), actuator type (Slotted), and bushing thread specification (1/4-32).

The 51CAD-E24-A15L qualifies as a direct substitute based on complete alignment with all specified electrical and mechanical parameters. The primary distinction between these parts is product status and regulatory compliance, not functional performance.

Parameter Comparison

Engineering Selection Recommendations

The 51CAD-E24-A15L is the direct functional equivalent of the 51CAD-E24-A15. Both parts share identical electrical and mechanical specifications, ensuring drop-in compatibility in circuit applications requiring a 10k Ohm 1W Cermet linear potentiometer with PC pin termination.

The 51CAD-E24-A15L is recommended for new designs and ongoing production due to its active product status and ROHS3 compliance. The original 51CAD-E24-A15, classified as obsolete, should be replaced with the 51CAD-E24-A15L in maintenance and retrofit applications where component availability is a concern.

For applications subject to RoHS or REACH regulatory requirements, the 51CAD-E24-A15L meets current compliance standards, whereas the 51CAD-E24-A15 does not.

Frequently Asked Questions (FAQ)

Q: Can the 51CAD-E24-A15L be used as a direct replacement for the 51CAD-E24-A15?
