Key Parameters

Substitute Part Grouping Explanation

Substitution of the 3296W-IND-100LF is based on the following critical parameters that must remain consistent:

Primary Matching Criteria:

• Resistance value: 10 Ohms (exact match required)
• Resistive material: Cermet (maintains performance characteristics)
• Manufacturer: Bourns Inc. (ensures design compatibility and quality standards)
• RoHS compliance: ROHS3 Compliant (regulatory requirement maintained)

The substitute part 3296W-1-100LF meets all primary matching criteria while providing additional specifications including defined power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), and active product status. This substitute belongs to the Trimpot® 3296 - Sealed series, which shares the same base product number (3296W) and cermet construction as the obsolete model.

Parameter Comparison

Engineering Selection Recommendations

The 3296W-1-100LF is the direct substitute for the obsolete 3296W-IND-100LF based on the following engineering factors:

Product Status Alignment: The substitute part maintains active product status with Bourns Inc., ensuring continued availability, technical support, and manufacturing consistency. The obsolete status of the original part necessitates transition to an active equivalent.

Regulatory Compliance: Both parts maintain ROHS3 compliance and equivalent environmental classifications, satisfying regulatory requirements for new designs and system replacements.

Electrical Specifications: The substitute provides defined electrical parameters (0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient) that establish clear performance boundaries for circuit design and validation.

Physical and Functional Compatibility: The substitute utilizes identical cermet resistive material and 10 Ohm resistance value, ensuring functional equivalence in trimmer potentiometer applications. The through-hole PC pin termination and rectangular form factor provide standard PCB integration.

Supply Chain Continuity: With 30,300 pieces in stock compared to the obsolete part's limited inventory, the substitute ensures long-term component availability for production and field service applications.

Frequently Asked Questions (FAQ)

Q: Can the 3296W-1-100LF directly replace the 3296W-IND-100LF in existing designs?

A: Yes. Both parts share identical resistance (10 Ohms), resistive material (cermet), and manufacturer (Bourns Inc.). The substitute provides fully specified electrical and mechanical parameters that establish compatibility with the original design intent.

Q: What is the significance of the different series designations (32XXX-IND vs. 3296 - Sealed)?

A: The series designation reflects product line evolution within Bourns' trimmer potentiometer portfolio. The 3296 - Sealed series represents the current active product line, while the 32XXX-IND series is obsolete. Both share the same base product number (3296W) and core specifications.

Q: Are there any packaging differences between these parts?

A: The substitute part is supplied in tube packaging, which is standard for active production components. The original part's packaging specification was not provided in the technical documentation.

Q: Does the substitute part meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant and have equivalent moisture sensitivity classifications (Not Applicable). The substitute additionally carries REACH Affected status and EAR99 ECCN classification.

Q: What is the practical difference in the number of turns (25 turns specified for the substitute)?

A: The substitute specifies 25 turns for adjustment, providing standard resolution for trimmer potentiometer applications. This parameter was not specified for the original part but represents typical performance for this component class.

Q: Is the 0.5W power rating of the substitute adequate for applications using the original part?

A: The substitute's 0.5W (1/2W) power rating is standard for this component category. If the original design required different power dissipation characteristics, this must be evaluated against specific circuit requirements.
