Key Parameters

Substitute Part Grouping Explanation

The 3296W-1-504LF qualifies as a direct substitute for the 3296W-IND-504LF based on the following critical parameters:

Matching Parameters:

• Resistance value: 500 kOhms (identical)
• Resistive material: Cermet (identical)
• Manufacturer: Bourns Inc. (identical)
• RoHS compliance: ROHS3 Compliant (identical)
• Base product family: 3296W series (same platform)

Substitution Basis: The 3296W-1-504LF represents an active production variant within the same Bourns 3296W product family. Both components share the same 500 kOhms resistance specification and cermet construction, establishing functional equivalence for applications requiring this resistance value and material composition. The substitute part is currently in active production status with substantial inventory availability, addressing the obsolescence of the original component.

Engineering Selection Recommendations

Primary Substitute: 3296W-1-504LF

The 3296W-1-504LF is the appropriate substitute for the obsolete 3296W-IND-504LF. Both components maintain ROHS3 compliance and are manufactured by Bourns Inc. with identical 500 kOhms resistance specifications and cermet construction.

The substitute part is currently in active production status with high inventory availability (65,600 pieces), ensuring supply chain continuity. The 3296W-1-504LF provides documented electrical specifications including 0.5W power rating, ±10% tolerance, and ±100ppm/°C temperature coefficient, offering enhanced technical clarity compared to the original component.

For applications where the original component specifications are fully defined in existing designs, the 3296W-1-504LF provides direct functional replacement. Verification of mechanical fit and electrical performance parameters within the specific application circuit is required prior to implementation.

Frequently Asked Questions (FAQ)

Q: Why is the 3296W-IND-504LF classified as obsolete?

A: The 3296W-IND-504LF is no longer in active production. The 3296W-1-504LF represents the current active production equivalent within the Bourns Trimpot® 3296 series, offering the same 500 kOhms resistance and cermet material composition.

Q: Are the 3296W-IND-504LF and 3296W-1-504LF electrically equivalent?

A: Both components share identical resistance values (500 kOhms) and resistive material (cermet). The 3296W-1-504LF provides additional documented specifications including 0.5W power rating, ±10% tolerance, and ±100ppm/°C temperature coefficient. Electrical equivalence is established for the 500 kOhms resistance function.

Q: What are the key differences between these parts?

A: The primary differences are product status (obsolete versus active) and documentation completeness. The 3296W-1-504LF includes specified power rating, tolerance, temperature coefficient, number of turns (25), adjustment type (top adjustment), mounting type (through hole), termination style (PC pins), and physical dimensions. The original component specifications for these parameters are not provided.

Q: Can the 3296W-1-504LF be used as a direct replacement in existing designs?

A: The 3296W-1-504LF is functionally equivalent for 500 kOhms trimmer potentiometer applications. Mechanical compatibility must be confirmed based on mounting type (through hole with PC pins), physical dimensions (0.375" x 0.190" face), and adjustment access (top adjustment). Circuit performance should be verified within the specific application.

Q: What is the packaging format for the substitute part?

A: The 3296W-1-504LF is supplied in tube packaging. This differs from the original component, which does not specify packaging format. Tube packaging is standard for through-hole trimmer potentiometers and is suitable for both manual and automated assembly processes.

Q: Are both parts RoHS compliant?

A: Yes. Both the 3296W-IND-504LF and 3296W-1-504LF are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and use.
