Substitute Part Grouping Explanation

Substitute parts for the 3262P-1-503 are classified based on electrical parameter equivalence and mechanical compatibility:

Direct Manufacturer Substitute (3262P-1-503LF): This Bourns part maintains identical electrical specifications and mechanical dimensions. The primary distinction is RoHS compliance status (ROHS3 Compliant versus RoHS non-compliant on the original). This substitute is selected when regulatory compliance is required without altering circuit performance.

Similar Manufacturer Substitute (64XR50KLF): This TT Electronics/BI part matches all critical electrical parameters: 50 kOhms resistance, 0.25W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 12-turn adjustment, cermet material, and PC pin termination. The face dimension differs slightly (0.250" x 0.165" versus 0.250" x 0.185"), and RoHS compliance status differs. This substitute is selected when cross-manufacturer sourcing is necessary while maintaining functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

For RoHS3 Compliance: Select 3262P-1-503LF when designs require ROHS3 compliance. This part maintains identical electrical and mechanical specifications to the original 3262P-1-503 while meeting current regulatory requirements.

For Cross-Manufacturer Sourcing: Select 64XR50KLF when supply from Bourns is constrained. This TT Electronics/BI part provides electrical equivalence across all critical parameters. The 0.020" reduction in face height (0.165" versus 0.185") must be evaluated for PCB layout compatibility and mechanical clearance in the application.

For Unrestricted Applications: The original 3262P-1-503 remains suitable for applications without RoHS compliance mandates.

Frequently Asked Questions (FAQ)

Q: Can 3262P-1-503LF be used as a direct replacement for 3262P-1-503?

A: Yes. Both parts are manufactured by Bourns and share identical electrical specifications (50 kOhms, 0.25W, ±10% tolerance, ±100ppm/°C) and mechanical dimensions (0.250" x 0.185" face). The primary difference is RoHS compliance status. Selection depends on regulatory requirements for the end application.

Q: What is the key difference between 3262P-1-503 and 64XR50KLF?

A: Both parts are electrically equivalent with matching resistance, power rating, tolerance, temperature coefficient, and adjustment characteristics. The 64XR50KLF has a slightly smaller face height (0.165" versus 0.185"). Verify PCB layout and mechanical clearance before substitution.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use PC pin termination for through-hole mounting and share the same electrical interface. Physical board layout must accommodate the face dimension differences, particularly the 0.020" height variation of the 64XR50KLF.

Q: Which substitute should be selected for new designs?

A: Selection is based on supply availability and compliance requirements. For RoHS-regulated markets, use 3262P-1-503LF. For cross-manufacturer sourcing, use 64XR50KLF after confirming mechanical fit. Verify inventory status and lead times with your supplier.

Q: Do these parts have different moisture sensitivity levels?

A: The 3262P-1-503 and 3262P-1-503LF list MSL as Not Applicable. The 64XR50KLF lists MSL 1 (Unlimited). This difference does not affect substitution for standard storage and handling conditions.
