Key Parameters

Substitute Part Grouping Explanation

Substitution of the 62PR100KLF is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match identically for direct substitution:

• Resistance value: 100 kOhms
• 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 dimension: Round - 0.250" Dia (6.35mm)
• RoHS compliance: ROHS3 Compliant

The 3329P-1-104LF from Bourns Inc. meets all these criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 3329P-1-104LF is the direct equivalent for the obsolete 62PR100KLF. Both components are ROHS3 compliant and share identical electrical and mechanical specifications. The Bourns component carries active product status, ensuring continued availability and supply chain reliability. The 3329P-1-104LF is supplied in tube packaging and maintains full compatibility with existing PCB layouts and through-hole assembly processes designed for the original 62PR100KLF.

Frequently Asked Questions (FAQ)

Q: Can the 3329P-1-104LF be used as a direct replacement for the 62PR100KLF?
