3296W-IND-102LF Trimmer Potentiometer Equivalent & Substitute Parts

Part Overview

The Bourns 3296W-IND-102LF is a 1 kOhms trimmer potentiometer featuring cermet resistive material and single-turn adjustment capability. This component is classified as obsolete and is no longer in active production. The part remains available in limited inventory (958 pieces) as new original stock.

Due to its obsolete status, locating replacement units from standard distribution channels presents supply chain challenges. Identifying equivalent and substitute parts ensures design continuity and project completion without requiring circuit redesign. The substitute part identified maintains the core electrical specifications while offering enhanced availability and active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 3296W-IND-102LF is based on the following criteria derived from the provided specifications:

Primary Matching Criteria:

• Resistance value: 1 kOhms (exact match required)
• Resistive material: Cermet (maintains electrical characteristics and performance envelope)
• Manufacturer: Bourns Inc. (same manufacturer ensures design consistency)
• RoHS compliance: ROHS3 Compliant (regulatory requirement maintained)

Substitute Identification: The 3296W-1-102LF qualifies as a direct substitute based on matching the primary electrical specification (1 kOhms cermet trimmer potentiometer) while offering active product status and significantly higher inventory availability (65,700 pieces). Both parts belong to the Bourns Trimpot® family and maintain identical resistance values and resistive material composition.

Compatibility Considerations: The substitute part introduces additional specifications not present in the original part data: 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 25-turn adjustment, top adjustment type, through-hole mounting with PC pins, and rectangular form factor (0.375" x 0.190" face). These specifications define the operational envelope and physical integration requirements for the substitute component.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility: The 3296W-1-102LF serves as a qualified substitute for the obsolete 3296W-IND-102LF based on matching core electrical specifications (1 kOhms, cermet material) and maintaining regulatory compliance (ROHS3 Compliant).

Product Status Advantage: The substitute part holds active product status with Bourns Inc., ensuring continued availability and manufacturing support. Inventory levels (65,700 pieces) substantially exceed the original part's remaining stock (958 pieces), providing supply chain security for production and field service applications.

Compliance Continuity: Both parts maintain ROHS3 compliance, satisfying environmental and regulatory requirements for electronic component procurement. The substitute part additionally carries REACH Affected status and EAR99 ECCN classification, providing complete regulatory documentation for international distribution.

Physical Integration: The substitute part specifies through-hole mounting with PC pins and rectangular form factor dimensions (0.375" x 0.190" face). Circuit board layout and mechanical assembly must accommodate these physical characteristics. The 25-turn adjustment mechanism and top adjustment type define the operational interface for calibration and tuning procedures.

Electrical Performance: The substitute part's specified parameters (0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient) establish the operational envelope. Circuit designs must ensure that applied power does not exceed 0.5W and that tolerance and temperature drift specifications align with system requirements.

Frequently Asked Questions (FAQ)

Q: Can the 3296W-1-102LF directly replace the 3296W-IND-102LF in existing designs?

A: Direct substitution is supported for applications where the substitute part's specified characteristics (0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 25-turn adjustment, through-hole PC pin mounting) are compatible with circuit requirements. Physical board layout must accommodate the rectangular form factor (0.375" x 0.190" face). Electrical circuit analysis must confirm that applied power remains within the 0.5W rating and that tolerance and temperature drift specifications satisfy system performance criteria.

Q: What are the key electrical differences between these parts?

A: Both parts share identical resistance value (1 kOhms) and resistive material (cermet). The substitute part specifies additional electrical parameters: 0.5W power rating, ±10% tolerance, and ±100ppm/°C temperature coefficient. The original part's data sheet does not include these specifications, indicating they were either not defined or not disclosed in available documentation.

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

A: Yes. The original part (3296W-IND-102LF) does not specify packaging details. The substitute part (3296W-1-102LF) is supplied in tube packaging and features through-hole PC pin termination with rectangular form factor dimensions (0.375" x 0.190" face, 9.53mm x 4.83mm). Circuit board design and assembly processes must accommodate these physical specifications.

Q: How many turns does the substitute part require for full resistance adjustment?

A: The 3296W-1-102LF features 25-turn adjustment with top adjustment type. This multi-turn design provides finer resolution for calibration and tuning compared to single-turn potentiometers, allowing more precise resistance setting within the ±10% tolerance specification.

Q: Do both parts maintain the same regulatory compliance status?

A: Both parts are ROHS3 Compliant. The substitute part additionally specifies REACH Affected status and EAR99 ECCN classification, providing expanded regulatory documentation. These certifications do not conflict with the original part's compliance requirements and support international distribution and procurement.

Q: What is the temperature performance specification for the substitute part?

A: The 3296W-1-102LF specifies ±100ppm/°C temperature coefficient. This parameter defines the resistance change per degree Celsius across the operating temperature range. Circuit designs requiring tight temperature stability must account for this drift specification in system performance calculations.

Q: Is the substitute part suitable for applications requiring higher power dissipation?

A: The 3296W-1-102LF is rated for 0.5W (1/2W) maximum power dissipation. Applications requiring higher power handling require alternative component selection. Circuit designs must ensure that applied power (calculated as I²R or V²/R) does not exceed this rating under any operating condition, including worst-case scenarios.
