Substitute Part Grouping Explanation

Substitution eligibility for the 3296X-1-253 is determined by strict equivalence across the following critical parameters:

• Resistance value: 25 kOhms
• Power rating: 0.5W (1/2W)
• Tolerance: ±10%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 25
• Adjustment type: Side Adjustment
• Resistive material: Cermet
• Mounting type: Through Hole
• Termination style: PC Pins
• Physical dimensions: Rectangular - 0.395" x 0.190" Face (10.03mm x 4.83mm)
• Series: Trimpot® 3296 - Sealed

The 3296X-1-253LF is a direct functional equivalent that maintains all electrical and mechanical specifications while offering improved compliance status. Substitution between these parts is valid for applications where the specified parameters are required.

Parameter Comparison

Engineering Selection Recommendations

Both the 3296X-1-253 and 3296X-1-253LF are active production parts from Bourns Inc. with identical electrical and mechanical specifications. The primary distinction is RoHS compliance status: the 3296X-1-253LF carries ROHS3 compliance, while the 3296X-1-253 is RoHS non-compliant. Both parts maintain REACH Affected status and share identical ECCN and HTSUS classifications.

Selection between these parts should be based on regulatory and compliance requirements applicable to the end application. For applications requiring RoHS3 compliance, the 3296X-1-253LF is the appropriate choice. For applications without RoHS compliance mandates, either part is functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Are the 3296X-1-253 and 3296X-1-253LF electrically interchangeable?

A: Yes. Both parts maintain identical resistance (25 kOhms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), and all other electrical specifications. They are direct functional equivalents.

Q: What is the difference between these two part numbers?

A: The primary difference is RoHS compliance status. The 3296X-1-253LF is ROHS3 compliant, while the 3296X-1-253 is RoHS non-compliant. All other specifications, including electrical performance and physical dimensions, are identical.

Q: Can I substitute the 3296X-1-253LF for the 3296X-1-253 in existing designs?

A: Yes, provided your application does not have specific requirements that mandate the non-compliant version. The ROHS3 compliant variant is a direct substitute with no functional differences.

Q: Are the physical dimensions identical?

A: Yes. Both parts share the same rectangular form factor of 0.395" x 0.190" face (10.03mm x 4.83mm) and are mounted identically as through-hole components with PC pin termination.

Q: What packaging is available for these parts?

A: Both the 3296X-1-253 and 3296X-1-253LF are supplied in tube packaging.

Q: Do these parts have the same temperature performance?

A: Yes. Both parts maintain a temperature coefficient of ±100ppm/°C across their operating range.
