Key Parameters

Substitute Part Grouping Explanation

Substitution of the 62PR20KLF is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match identically for direct substitution:

• Resistance value: 20 kOhms
• Power rating: 0.5W
• 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
• Package diameter: 0.250" (6.35mm)

The 3329P-1-203LF from Bourns Inc. meets all specified parameters and qualifies as a direct equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The 3329P-1-203LF is the qualified substitute for the 62PR20KLF. Both components are ROHS3 compliant and share identical electrical and mechanical specifications. The primary distinction is product status: the 62PR20KLF is obsolete while the 3329P-1-203LF remains in active production. For new designs or ongoing procurement, the 3329P-1-203LF provides continuity of supply and long-term availability. The 3329P-1-203LF is packaged in tube format, whereas original packaging information for the 62PR20KLF was not specified.

Frequently Asked Questions (FAQ)
