62PR50KLF Trimmer Potentiometer - Equivalent & Substitute Parts

Part Overview

The 62PR50KLF is a 50 kOhm, 0.5W through-hole trimmer potentiometer manufactured by TT Electronics/BI. This cermet-based component features top adjustment with PC pin termination and a 1-turn rotation mechanism. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing maintenance, repair, and legacy system support. Equivalent alternatives must maintain identical electrical specifications and mechanical form factors to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 62PR50KLF is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must match the following criteria:

• Resistance value: 50 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 dimensions: Round - 0.250" Dia (6.35mm)
• RoHS compliance: ROHS3 Compliant

The 3329P-1-503LF from Bourns Inc. meets all specified parameters and qualifies as a direct equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The 3329P-1-503LF represents the qualified substitute for the obsolete 62PR50KLF. Both components are ROHS3 compliant and share identical electrical and mechanical specifications. The Bourns 3329P-1-503LF maintains active product status, ensuring ongoing availability and supply chain continuity. Selection of the substitute part is supported by complete parameter equivalence and regulatory compliance alignment.

Frequently Asked Questions (FAQ)

Q: Can the 3329P-1-503LF be used as a direct replacement for the 62PR50KLF?

A: Yes. Both components share identical resistance value, power rating, tolerance, temperature coefficient, number of turns, adjustment type, resistive material, mounting type, termination style, and physical dimensions. Direct substitution is supported.

Q: What is the primary difference between these two parts?

A: The 62PR50KLF is obsolete, while the 3329P-1-503LF is an active product from Bourns Inc. The 3329P-1-503LF is packaged in tubes, whereas the original part's packaging specification was not provided. Both meet ROHS3 compliance requirements.

Q: Are there any compliance or regulatory differences?

A: Both parts are ROHS3 compliant. The 3329P-1-503LF is REACH Affected, while the original part's REACH status was REACH Unaffected. Both carry the same ECCN (EAR99) and HTSUS (8533.40.8050) classifications.

Q: What parameters must remain constant for substitution?

A: Resistance value, power rating, tolerance, temperature coefficient, number of turns, adjustment type, resistive material, mounting type, termination style, and physical dimensions must all match exactly for direct substitution.
