62PR1KLF Trimmer Potentiometer - Equivalent & Substitute Parts

Part Overview

The 62PR1KLF is a 1 kOhm, 0.5W through-hole trimmer potentiometer manufactured by TT Electronics/BI. This cermet-based component features top adjustment with PC pin termination and is designed for precision resistance tuning applications. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance requirements. Active alternatives with identical electrical and mechanical specifications are available from qualified manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 62PR1KLF is determined by strict equivalence across all electrical and mechanical parameters. The following criteria must be met for a part to serve as a direct substitute:

• Resistance value: 1 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-1-102LF from Bourns Inc. meets all specified parameters and qualifies as a direct equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The 3329P-1-102LF is the qualified substitute for the obsolete 62PR1KLF. Both components are ROHS3 compliant and meet identical electrical and mechanical specifications. The Bourns part maintains active product status, ensuring long-term availability and supply chain continuity. Selection of the 3329P-1-102LF eliminates obsolescence risk while preserving all functional and performance characteristics required for the application.

Frequently Asked Questions (FAQ)

Q: Can the 3329P-1-102LF be used as a direct replacement for the 62PR1KLF?

A: Yes. Both parts share identical electrical parameters (1 kOhm resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient), mechanical configuration (through-hole PC pins, top adjustment, cermet material), and physical dimensions (0.250" diameter). RoHS3 compliance is maintained across both parts.

Q: What is the primary reason for substitution?

A: The 62PR1KLF is obsolete. The 3329P-1-102LF is an active product from Bourns Inc., providing assured availability and supply chain stability.

Q: Are there packaging differences between these parts?

A: The 62PR1KLF is supplied in standard packaging, while the 3329P-1-102LF is packaged in tubes. Both are suitable for through-hole PCB assembly processes.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 62PR1KLF and 3329P-1-102LF are ROHS3 compliant. The 3329P-1-102LF is REACH affected, while the 62PR1KLF is REACH unaffected; however, this does not affect functional equivalence.

Q: Are the physical dimensions identical?

A: Yes. Both parts feature a round form factor with 0.250" diameter (6.35mm), ensuring identical PCB footprint and mounting compatibility.
