Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3329P-1-502 are classified based on electrical parameter equivalence and mechanical compatibility. All substitute parts maintain identical electrical specifications: 5 kΩ resistance, 0.5W power rating, ±10% tolerance, ±100 ppm/°C temperature coefficient, 1-turn adjustment, top adjustment type, cermet resistive material, through-hole mounting, and PC pin termination.

Mechanical variations exist in physical dimensions and packaging format. Substitution is permissible when the circuit board layout accommodates the physical size differences and packaging requirements align with assembly processes.

Key Parameters Determining Substitution:

• Resistance value: 5 kΩ
• Power rating: 0.5W
• Tolerance: ±10%
• Temperature coefficient: ±100 ppm/°C
• Adjustment type: Top Adjustment
• Termination: PC Pins
• Mounting: Through Hole

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Manufacturer): The 3329P-1-502LF is a direct equivalent manufactured by Bourns Inc. with identical electrical and mechanical specifications. The primary difference is RoHS3 compliance status. Selection of 3329P-1-502LF is appropriate when RoHS3 compliance is required for the end application.

Cross-Manufacturer Substitutes (TT Electronics/BI): The 25PR5KLF, 72PMR5KLF, and 82PR5KLF are functionally equivalent alternatives from TT Electronics/BI. All maintain identical electrical parameters and through-hole PC pin termination.

• 25PR5KLF: Square footprint (0.270" x 0.270") in tube packaging. RoHS Compliant. Select when board layout accommodates square geometry and tube packaging is required.
• 72PMR5KLF: Larger square footprint (0.375" x 0.375") in bulk packaging. ROHS3 Compliant. Select when larger physical envelope is acceptable and bulk packaging aligns with assembly requirements.
• 82PR5KLF: Round footprint (0.250" Dia, matching original) in bulk packaging. ROHS3 Compliant. Select when round geometry is required and bulk packaging is compatible with assembly processes.

All substitute parts carry Active product status and are suitable for new designs and replacement applications.

Frequently Asked Questions (FAQ)

Q: Can 3329P-1-502LF replace 3329P-1-502 in existing designs? A: Yes. Both parts are manufactured by Bourns Inc. with identical electrical specifications (5 kΩ, 0.5W, ±10% tolerance, ±100 ppm/°C) and mechanical dimensions (round, 0.250" diameter). The primary difference is RoHS3 compliance status of the LF variant.

Q: What is the difference between tube and bulk packaging? A: Tube packaging contains individual components in protective tubes, typically used for lower-volume orders and manual assembly. Bulk packaging contains loose components, typically used for high-volume automated assembly. Electrical and mechanical specifications remain identical.

Q: Can TT Electronics/BI parts substitute for Bourns parts? A: Yes, when electrical parameters match. The 25PR5KLF, 72PMR5KLF, and 82PR5KLF maintain identical electrical specifications (5 kΩ, 0.5W, ±10%, ±100 ppm/°C, 1-turn, top adjustment, cermet, through-hole, PC pins). Physical dimensions vary; verify board layout compatibility before selection.

Q: What are the physical dimension differences among substitutes? A: The 3329P-1-502 and 82PR5KLF feature round geometry (0.250" diameter). The 25PR5KLF has a smaller square footprint (0.270" x 0.270"). The 72PMR5KLF has a larger square footprint (0.375" x 0.375"). Verify PCB layout clearances before substitution.

Q: Are all substitute parts RoHS compliant? A: The original 3329P-1-502 is RoHS non-compliant. The 3329P-1-502LF, 72PMR5KLF, and 82PR5KLF are ROHS3 Compliant. The 25PR5KLF is RoHS Compliant. Compliance status should be verified against end-application requirements.

Q: Can these parts be used interchangeably in the same circuit? A: Yes, provided circuit board layout accommodates physical dimension differences. All parts maintain identical electrical performance: 5 kΩ resistance, 0.5W power dissipation, ±10% tolerance, and ±100 ppm/°C temperature coefficient.
