Substitute Part Grouping Explanation

Substitution of the 3296W-IND-503LF is determined by the following core electrical and mechanical parameters:

Primary Substitution Criteria:

• Resistance value: 50 kOhms (exact match required)
• Resistive material: Cermet (maintains performance characteristics)
• Manufacturer: Bourns Inc. (ensures design compatibility within product family)
• RoHS compliance: ROHS3 Compliant (regulatory requirement match)

The substitute part 3296W-1-503LF maintains identical resistance and resistive material specifications while providing an active, currently manufactured alternative. This part belongs to the Trimpot® 3296 - Sealed series, which represents the modern equivalent within Bourns' trimmer potentiometer portfolio. The substitution is valid based on matching core electrical parameters and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

The 3296W-1-503LF serves as the direct substitute for the obsolete 3296W-IND-503LF based on the following engineering criteria:

Electrical Compatibility: Both parts maintain identical 50 kOhms resistance specifications and cermet resistive material composition, ensuring functional equivalence in circuit applications.

Regulatory Compliance: Both components are ROHS3 compliant and carry Not Applicable moisture sensitivity ratings, meeting current environmental and reliability standards.

Product Lifecycle Status: The substitute part is classified as active and currently manufactured, providing assured long-term availability and supply chain continuity compared to the obsolete main part.

Series Alignment: While the main part belongs to the Trimpot® 32XXX-IND series and the substitute to the Trimpot® 3296 - Sealed series, both are Bourns Inc. products within the established Trimpot® trimmer potentiometer family, maintaining design consistency.

Selection of the 3296W-1-503LF is appropriate for applications requiring the 50 kOhms resistance value with cermet construction and current manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can the 3296W-1-503LF directly replace the 3296W-IND-503LF in existing designs?

A: Yes. Both parts share identical resistance values (50 kOhms) and resistive material (cermet). The substitute is manufactured by the same supplier (Bourns Inc.) and maintains ROHS3 compliance. Verification of mechanical fit and termination compatibility with your specific PCB layout is required, as the substitute features PC pins through-hole termination and specified rectangular dimensions.

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

A: The main part (3296W-IND-503LF) is obsolete with unspecified technical parameters. The substitute (3296W-1-503LF) is an active product with fully documented specifications including 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 25-turn adjustment, top adjustment type, and through-hole PC pin termination. The substitute belongs to the sealed Trimpot® 3296 series.

Q: Are there packaging differences between these parts?

A: Yes. The substitute part is supplied in tube packaging, whereas the main part packaging is not specified. Confirm packaging requirements for your procurement and assembly processes.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the 3296W-IND-503LF and 3296W-1-503LF are ROHS3 compliant. The substitute additionally carries REACH Affected status and EAR99 ECCN classification, indicating compliance with current export and environmental regulations.

Q: What is the adjustment mechanism difference?

A: The substitute part features top adjustment, allowing access to the potentiometer adjustment from the top surface of the component. This is a standard feature of the Trimpot® 3296 - Sealed series and provides convenient field or manufacturing adjustment capability.

Q: Is the 25-turn specification important for my application?

A: The number of turns affects adjustment resolution and ease of tuning. The substitute provides 25 turns, enabling finer adjustment control compared to lower-turn alternatives. Confirm this specification aligns with your application's tuning requirements and adjustment frequency.
