Substitute Part Grouping Explanation

The RHS1K5E qualifies as a direct equivalent substitute based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Resistance value: 1.5k Ohm (±10% tolerance)
• Power dissipation: 25W
• Taper characteristic: Linear
• Resistive element: Wirewound construction
• Termination: Solder Lug
• Mounting configuration: Panel Mount with 3/8-32 bushing thread
• Physical dimensions: Round body 1.560" diameter with flatted actuator (0.750" length, 0.250" diameter)
• Rotation range: 300°

The RHS1K5E maintains full compatibility with the RHS1K5 across all specified electrical and mechanical parameters, enabling direct substitution in existing designs and assemblies.

Parameter Comparison

Engineering Selection Recommendations

The RHS1K5E provides a direct functional equivalent to the RHS1K5 with identical electrical performance and mechanical compatibility. The primary distinction is regulatory compliance: the RHS1K5E achieves ROHS3 compliance and documents REACH unaffected status, whereas the RHS1K5 is RoHS non-compliant. For applications subject to RoHS3 or REACH regulatory requirements, the RHS1K5E is the appropriate selection. Both parts maintain active product status with established manufacturing support and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can RHS1K5E be used as a direct replacement for RHS1K5 in existing assemblies?

A: Yes. The RHS1K5E is electrically and mechanically identical to the RHS1K5 across all specified parameters, including resistance value, power rating, taper, termination style, mounting configuration, and physical dimensions. Direct substitution is valid without design modification.

Q: What is the primary difference between RHS1K5 and RHS1K5E?

A: The RHS1K5E achieves ROHS3 compliance and documents REACH unaffected status, while the RHS1K5 is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns with panel mounting or actuator engagement?

A: No. Both parts feature identical panel mount configuration with 3/8-32 bushing thread, flatted actuator design (0.750" length, 0.250" diameter), and body dimensions (1.560" diameter). Mechanical fit and actuator engagement are equivalent.

Q: Which part should be selected for new designs?

A: The RHS1K5E is recommended for new designs due to ROHS3 compliance and documented REACH status, ensuring alignment with current regulatory requirements.

Q: Is the tolerance specification identical between both parts?

A: Yes. Both RHS1K5 and RHS1K5E maintain ±10% resistance tolerance, ensuring equivalent precision in resistance adjustment applications.
