• 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 0.240" Face (10.03mm x 6.10mm)
• Series: Trimpot® 3299 - Sealed

All electrical and mechanical parameters are identical between the main part and substitute, ensuring functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 3299Z-1-102 and 3299Z-1-102LF are active production parts from Bourns Inc. with identical electrical and mechanical specifications. The primary distinction is RoHS compliance status. The 3299Z-1-102LF carries ROHS3 compliance, while the 3299Z-1-102 is RoHS non-compliant. Selection between these parts should be based on application requirements for RoHS compliance and regulatory jurisdiction. Both parts share identical REACH and ECCN classifications. Functional performance in circuit applications is equivalent.

Frequently Asked Questions (FAQ)

Q: Can the 3299Z-1-102LF replace the 3299Z-1-102 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The 3299Z-1-102LF is suitable for applications requiring ROHS3 compliance. Verify your application's compliance requirements before selection.

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

A: The primary difference is RoHS compliance status. The 3299Z-1-102LF is ROHS3 compliant, while the 3299Z-1-102 is not. All other specifications, including resistance, power rating, tolerance, temperature coefficient, adjustment type, and physical dimensions, are identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical rectangular dimensions of 0.395" x 0.240" face (10.03mm x 6.10mm) and use the same through-hole PC pin termination.

Q: Do these parts have the same temperature coefficient?

A: Yes. Both parts have a temperature coefficient of ±100ppm/°C, ensuring equivalent thermal stability across operating ranges.

Q: Which part should I select for new designs?

A: Selection depends on regulatory and compliance requirements. For applications requiring ROHS3 compliance, use 3299Z-1-102LF. For applications without RoHS requirements, either part is suitable based on availability.
