Key Parameters

Substitute Part Grouping Explanation

Substitution of the 3296W-IND-104LF is determined by the following critical parameters that must align between the original and substitute component:

Primary Substitution Criteria:

• Resistance value: 100 kOhms (exact match required)
• Resistive material: Cermet (maintains electrical performance characteristics)
• Manufacturer: Bourns Inc. (ensures design consistency and reliability)
• RoHS compliance: ROHS3 Compliant (regulatory requirement match)

The substitute part 3296W-1-104LF meets all primary substitution criteria while providing additional specifications including defined power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), and active product status. This substitute maintains the core functional parameters of the obsolete original while offering enhanced documentation and ongoing availability.

Parameter Comparison

Engineering Selection Recommendations

The 3296W-1-104LF serves as the direct substitute for the obsolete 3296W-IND-104LF based on the following engineering factors:

Compliance Alignment: Both components maintain ROHS3 compliance and share identical moisture sensitivity classification (Not Applicable), ensuring regulatory requirements are satisfied in replacement scenarios.

Product Status: The substitute part maintains active product status with Bourns Inc., providing assured long-term availability, documented specifications, and manufacturing consistency. The original part's obsolete status necessitates transition to the active substitute for new procurements and system maintenance.

Electrical Equivalence: Both components specify 100 kOhms resistance with cermet resistive material, establishing functional equivalence for circuit applications. The substitute provides explicit tolerance (±10%) and temperature coefficient (±100ppm/°C) specifications, enabling precise performance prediction in temperature-sensitive applications.

Physical and Functional Compatibility: The substitute defines through-hole mounting with PC pin termination and top adjustment configuration, supporting direct integration into existing printed circuit board designs originally specified for the 3296W-IND-104LF.

Frequently Asked Questions (FAQ)

Q: Can the 3296W-1-104LF directly replace the 3296W-IND-104LF in existing designs?

A: Yes. Both components share identical resistance value (100 kOhms), resistive material (cermet), and RoHS compliance status. The substitute provides fully documented specifications including power rating, tolerance, and temperature coefficient, enabling direct substitution in circuit applications originally designed for the obsolete part.

Q: What is the significance of the series designation change from Trimpot® 32XXX-IND to Trimpot® 3296 - Sealed?

A: The series designation reflects manufacturing evolution within Bourns' trimmer potentiometer product line. The substitute part belongs to the current Trimpot® 3296 sealed series, which represents the active production equivalent of the discontinued 32XXX-IND series. Both series maintain identical core electrical specifications for the 100 kOhms resistance value.

Q: Are there packaging differences between the original and substitute parts?

A: The original part number does not specify packaging details. The substitute part 3296W-1-104LF is supplied in tube packaging. Verification of packaging requirements for your specific procurement and assembly processes is necessary when transitioning from the obsolete part.

Q: How do the specified electrical parameters of the substitute affect circuit performance?

A: The substitute specifies 0.5W power rating, ±10% tolerance, and ±100ppm/°C temperature coefficient. These parameters define the component's operational limits and accuracy characteristics. Applications requiring different power dissipation, tolerance, or temperature stability specifications must evaluate whether these substitute parameters align with circuit requirements.

Q: Is the 25-turn adjustment specification of the substitute compatible with the original design?

A: The original part does not specify the number of turns. The substitute provides 25-turn adjustment with top adjustment configuration. Circuit designs requiring specific adjustment resolution or mechanical interface characteristics should confirm compatibility with this 25-turn specification before implementation.

Q: What certifications and compliance standards apply to the substitute part?

A: The 3296W-1-104LF maintains ROHS3 compliance and REACH affected status. The part is classified under ECCN EAR99 and HTSUS code 8533.40.8050. These certifications and classifications ensure regulatory compliance for applications subject to environmental and export control requirements.
