Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3296Z-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 3296Z-1-253LF meets all electrical and mechanical specifications required for direct substitution. The primary distinction is RoHS compliance status, which may be a determining factor for specific applications or regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the 3296Z-1-253 and 3296Z-1-253LF are active production parts manufactured by Bourns Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on regulatory and compliance requirements:

The 3296Z-1-253LF is ROHS3 compliant, making it the appropriate choice for applications subject to RoHS directives or customer specifications requiring RoHS compliance. The 3296Z-1-253 is RoHS non-compliant and should be selected only when RoHS compliance is not a requirement.

Both parts are REACH Affected and carry the same ECCN and HTSUS classifications. Inventory availability may also influence selection, with 1176 pcs of the 3296Z-1-253LF and 1039 pcs of the 3296Z-1-253 currently in stock.

Frequently Asked Questions (FAQ)

Q: Can the 3296Z-1-253LF be used as a direct replacement for the 3296Z-1-253?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including resistance, power rating, tolerance, temperature coefficient, number of turns, adjustment type, resistive material, mounting type, termination style, and physical dimensions.

Q: What is the primary difference between these two parts?

A: The 3296Z-1-253LF is ROHS3 compliant, while the 3296Z-1-253 is RoHS non-compliant. All other specifications are equivalent.

Q: Which part should I select for a new design?

A: If your application or customer requirements mandate RoHS compliance, select the 3296Z-1-253LF. If RoHS compliance is not required, either part may be used based on availability and cost considerations.

Q: Are there any differences in package or mounting between these parts?

A: No. Both parts use identical through-hole PC pin termination and rectangular packaging (0.395" x 0.190" face, 10.03mm x 4.83mm).

Q: Do these parts have different temperature operating ranges?

A: No. Both parts share the same temperature coefficient of ±100ppm/°C.
