Substitute Part Grouping Explanation

Substitution for the 3296Z-1-254 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications for resistance value, power rating, tolerance, temperature coefficient, number of turns, adjustment type, resistive material composition, mounting configuration, termination style, and physical dimensions. The primary distinction between the main part and its substitute relates to RoHS compliance status and lead-free termination processing, which do not alter functional performance or circuit compatibility when electrical and mechanical parameters remain constant.

Key Parameters Determining Substitution:

• Resistance: 250 kOhms
• Power Rating: 0.5W
• 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: 0.395" x 0.190" Face

Engineering Selection Recommendations

The 3296Z-1-254LF serves as a direct functional equivalent to the 3296Z-1-254, with all electrical and mechanical parameters held constant. Selection between these parts should be based on regulatory and compliance requirements applicable to the end application.

3296Z-1-254: Select this part number for applications where RoHS non-compliant components are acceptable or required by specification. Both parts maintain identical functional performance.

3296Z-1-254LF: Select this part number for applications requiring ROHS3 compliance. The "LF" designation indicates lead-free termination processing. Functional performance and circuit compatibility remain unchanged from the standard variant.

Both parts are active products from Bourns Inc., carry identical REACH and ECCN classifications, and are classified under the same HTSUS code. Inventory availability should be evaluated based on procurement lead times and supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Are the 3296Z-1-254 and 3296Z-1-254LF electrically interchangeable?

A: Yes. Both parts have identical resistance values (250 kOhms), power ratings (0.5W), tolerance (±10%), temperature coefficients (±100ppm/°C), and all other electrical specifications. They are functionally equivalent in circuit applications.

Q: What does the "LF" suffix in 3296Z-1-254LF indicate?

A: The "LF" designation indicates lead-free termination processing and ROHS3 compliance. This affects manufacturing and environmental compliance status but does not alter electrical or mechanical performance.

Q: Can I use 3296Z-1-254LF as a replacement for 3296Z-1-254 in existing designs?

A: Yes, provided your application or regulatory requirements do not specifically mandate the non-compliant variant. The parts are mechanically and electrically identical, with identical through-hole PC pin termination and physical dimensions.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts have identical rectangular form factors of 0.395" x 0.190" face dimensions (10.03mm x 4.83mm). They occupy the same PCB footprint and mounting space.

Q: What is the difference in packaging between these part numbers?

A: Both parts are supplied in tube packaging. No packaging differences exist between the variants.

Q: Do these parts have different temperature operating ranges?

A: No. Both parts share identical temperature coefficient specifications of ±100ppm/°C. Temperature performance is equivalent.

Q: Which part should I specify for new designs?

A: Selection depends on your application's compliance requirements. For new designs subject to RoHS regulations, specify 3296Z-1-254LF. For applications without RoHS requirements, either part is acceptable based on availability and procurement considerations.
