Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3266X-1-502 are qualified based on matching the following critical electrical and mechanical parameters: 5 kOhm resistance value, 0.25W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 12-turn adjustment, side adjustment type, cermet resistive material, through-hole mounting, and PC pin termination. All substitute parts maintain these core specifications, ensuring functional equivalence in circuit applications. Variations in physical dimensions (face size) and compliance certifications are noted but do not affect electrical substitutability when mechanical clearance permits.

Parameter Comparison

Engineering Selection Recommendations

The 3266X-1-502LF is the primary direct equivalent, maintaining identical electrical specifications and physical dimensions while offering ROHS3 compliance. This part is suitable for applications requiring RoHS certification.

The 64PR5KLF and 64XR5KLF are functionally equivalent alternatives from TT Electronics/BI. Both offer RoHS compliance and REACH unaffected status. The 64PR5KLF features a square face dimension (0.250" x 0.250"), while the 64XR5KLF maintains a rectangular profile (0.250" x 0.165") closer to the original specification. Selection between these alternatives depends on available board space and compliance requirements. The 64XR5KLF provides the highest inventory availability at 8684 units.

Frequently Asked Questions (FAQ)

Q: Can 3266X-1-502LF be used as a direct replacement for 3266X-1-502?

A: Yes. Both parts share identical electrical parameters (5 kOhm, 0.25W, ±10% tolerance, ±100ppm/°C), adjustment characteristics (12-turn side adjustment), and physical dimensions (0.250" x 0.170" face). The primary difference is RoHS compliance status.

Q: What are the key differences between Bourns and TT Electronics/BI alternatives?

A: The Bourns 3266X-1-502LF maintains the original rectangular face dimension. The TT Electronics/BI 64PR5KLF and 64XR5KLF offer equivalent electrical performance with different physical footprints. The 64PR5KLF has a square face (0.250" x 0.250"), while the 64XR5KLF has a rectangular face (0.250" x 0.165"). All three alternatives are RoHS compliant.

Q: Are there mechanical compatibility concerns when substituting these parts?

A: Physical dimensions vary slightly. The 64PR5KLF square face may require board layout verification. The 64XR5KLF rectangular dimension (0.165" height) differs marginally from the original (0.170" height). Confirm available mounting clearance before selection.

Q: Which substitute part offers the best compliance profile?

A: The 64PR5KLF and 64XR5KLF both provide RoHS compliance and REACH unaffected status, making them suitable for applications with strict environmental compliance requirements.

Q: How do inventory levels affect part selection?

A: The 64XR5KLF offers the highest inventory availability at 8684 units, followed by 3266X-1-502LF at 2012 units and 64PR5KLF at 1796 units. The original 3266X-1-502 has 937 units in stock.
