Substitute Part Grouping Explanation

Substitution for the 51CAD-E24-B15 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part 51CAD-E24-B15L maintains identical specifications in the following key areas:

• Resistance value: 10k Ohm
• Power rating: 0.5W, 1/2W
• Tolerance: ±20%
• Taper characteristic: Linear
• Gang configuration: Single gang
• Resistive material: Conductive plastic
• Rotation angle: 290°
• Termination: PC pins
• Mounting configuration: Panel mount
• Physical dimensions: Rectangular 0.521" x 0.492" face
• Actuator specifications: Slotted type, 0.750" length, 0.125" diameter
• Bushing thread: 1/4-32

The substitute differs only in packaging format (bulk versus standard) and regulatory compliance status, with no impact on electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The 51CAD-E24-B15L serves as the direct functional equivalent to the obsolete 51CAD-E24-B15. Selection between these parts is determined by regulatory and compliance requirements rather than electrical or mechanical performance.

For applications requiring RoHS3 compliance and REACH compliance status, the 51CAD-E24-B15L is the appropriate selection. This part maintains active product status with Bourns Inc., ensuring continued availability and supply chain reliability.

For legacy systems or applications where RoHS3 compliance is not mandated, the 51CAD-E24-B15 remains functionally equivalent, though its obsolete status may present long-term sourcing challenges.

Frequently Asked Questions (FAQ)

Q: Can the 51CAD-E24-B15L be used as a direct replacement for the 51CAD-E24-B15?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including resistance value, power rating, taper, termination style, and physical dimensions. The substitute differs only in packaging format and regulatory compliance status.

Q: What is the difference between the two part numbers?

A: The primary differences are product status (obsolete versus active), RoHS compliance (non-compliant versus ROHS3 compliant), and REACH status (unaffected versus affected). Electrical and mechanical performance are identical.

Q: Are there any compatibility concerns when substituting the 51CAD-E24-B15L for the 51CAD-E24-B15?

A: No compatibility concerns exist. Both parts feature identical mounting configurations, bushing threads, actuator specifications, and PC pin termination. Direct board-level substitution is supported.

Q: What packaging formats are available?

A: The 51CAD-E24-B15 is available in standard packaging, while the 51CAD-E24-B15L is supplied in bulk packaging. Packaging format does not affect component performance or compatibility.

Q: Should I select the substitute based on compliance requirements?

A: Yes. If your application or region requires RoHS3 or REACH compliance, the 51CAD-E24-B15L is the appropriate selection. For applications without these requirements, either part is functionally suitable, though the active status of the 51CAD-E24-B15L provides better long-term availability assurance.
