Substitute Part Grouping Explanation

Substitution eligibility for the 3329X-1-101 is determined by strict equivalence across the following critical parameters:

• Resistance value: 100 Ohms
• Power rating: 0.5W (1/2W)
• Tolerance: ±10%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 1
• Adjustment type: Side Adjustment
• Resistive material: Cermet
• Mounting type: Through Hole
• Termination style: PC Pins
• Physical dimensions: Rectangular - 0.260" x 0.330" Face (6.60mm x 8.38mm)
• Series: Trimpot® 3329 - Sealed

The substitute part 3329X-1-101LF maintains identical electrical and mechanical specifications, with the primary distinction being RoHS compliance status. Both parts are manufactured by Bourns Inc. and belong to the same sealed Trimpot® 3329 product line.

Parameter Comparison

Engineering Selection Recommendations

Both the 3329X-1-101 and 3329X-1-101LF are active production parts manufactured by Bourns Inc. with identical electrical and mechanical specifications. Selection between these parts is determined by regulatory and compliance requirements:

• Use 3329X-1-101LF for applications requiring ROHS3 compliance
• Use 3329X-1-101 where RoHS compliance is not mandated

Both parts are REACH Affected and carry EAR99 export classification. Inventory availability should be verified at the time of procurement, as stock levels vary.

Frequently Asked Questions (FAQ)

Q: Are the 3329X-1-101 and 3329X-1-101LF electrically interchangeable?

A: Yes. Both parts have identical resistance (100 Ohms), 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 3329X-1-101LF is ROHS3 compliant, while the 3329X-1-101 is RoHS non-compliant. All other specifications, including physical dimensions, mounting type, and termination style, are identical.

Q: Can I use 3329X-1-101LF as a drop-in replacement for 3329X-1-101?

A: Yes. The parts are mechanically and electrically identical with the same rectangular form factor (0.260" x 0.330" face), PC pin termination, and through-hole mounting. No circuit modifications are required.

Q: Are there any packaging differences?

A: No. Both parts are supplied in tube packaging.

Q: Which part should I specify for new designs?

A: Specify 3329X-1-101LF for new designs to ensure ROHS3 compliance and future regulatory alignment.
