Key Parameters

Substitute Part Grouping Explanation

Substitution of the 62PR10LF is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must match the following criteria:

• Resistance value: 10 Ohms
• Power rating: 0.5W (1/2W)
• Tolerance: ±10%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 1
• Adjustment type: Top Adjustment
• Resistive material: Cermet
• Mounting type: Through Hole
• Termination style: PC Pins
• Physical size: Round - 0.250" Dia (6.35mm)
• RoHS3 compliance

The 3329P-1-100LF from Bourns Inc. meets all specified parameters and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 3329P-1-100LF is a direct functional equivalent to the 62PR10LF. Both components are ROHS3 compliant and share identical electrical and mechanical specifications. The primary distinction is product status: the 62PR10LF is obsolete while the 3329P-1-100LF remains in active production by Bourns Inc., ensuring continued availability and supply chain reliability.

For applications requiring the 62PR10LF, the 3329P-1-100LF provides equivalent performance with the advantage of active manufacturer support and ongoing availability.

Frequently Asked Questions (FAQ)

Q: Can the 3329P-1-100LF be used as a direct replacement for the 62PR10LF?

A: Yes. Both components share identical electrical parameters (10 Ohms, 0.5W, ±10% tolerance, ±100ppm/°C temperature coefficient), mechanical configuration (through-hole PC pins, 1.0 turn top adjustment), and physical dimensions (0.250" diameter). RoHS3 compliance is equivalent.

Q: What is the difference between the 62PR10LF and 3329P-1-100LF?

A: The components are electrically and mechanically identical. The 62PR10LF is manufactured by TT Electronics/BI and is obsolete. The 3329P-1-100LF is manufactured by Bourns Inc. (Trimpot® 3329 series) and remains in active production.

Q: Are there packaging differences between these parts?

A: The 62PR10LF is supplied in standard packaging. The 3329P-1-100LF is supplied in tube packaging. Both are suitable for through-hole PCB assembly.

Q: Does the 3329P-1-100LF meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant and carry the same ECCN (EAR99) and HTSUS (8533.40.8050) classifications.

Q: Why should I consider the 3329P-1-100LF over the 62PR10LF?

A: The 3329P-1-100LF is the recommended choice for new designs and ongoing applications due to its active production status, ensuring long-term availability and supply chain continuity.
