Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3362M-1-102RLF are identified based on the following critical parameters:

• Resistance value: 1 kOhms
• Power rating: 0.5W (1/2W)
• Tolerance: ±10%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 1
• Adjustment type: Side Adjustment
• Resistive material: Cermet
• Mounting type: Through Hole
• Termination style: PC Pins

The TT Electronics/BI 72XR1KLF meets all electrical specifications and functional requirements. Physical dimensions differ (square 0.375" x 0.375" versus rectangular 0.275" x 0.260"), and packaging format differs (Bulk versus Tape & Reel), which may affect board layout and procurement workflows but do not alter electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the 3362M-1-102RLF and 72XR1KLF are Active status components with ROHS3 compliance and EAR99 ECCN classification. Selection between these parts should be based on:

• Board layout constraints: The 3362M-1-102RLF occupies a smaller rectangular footprint (6.99mm x 6.60mm) compared to the 72XR1KLF square footprint (9.53mm x 9.53mm).
• Packaging requirements: The 3362M-1-102RLF is supplied in Tape & Reel format; the 72XR1KLF is supplied in Bulk format.
• Supply availability: Current inventory shows 1076 units of 3362M-1-102RLF and 2606 units of 72XR1KLF.

All electrical and functional parameters are equivalent, ensuring direct substitution capability from an electrical performance standpoint.

Frequently Asked Questions (FAQ)

Q: Can the 72XR1KLF replace the 3362M-1-102RLF in an existing design?

A: Yes, from an electrical standpoint. Both components share identical resistance, power rating, tolerance, temperature coefficient, number of turns, adjustment type, resistive material, mounting type, and termination style. Physical dimensions differ, requiring verification of available board space.

Q: What are the key differences between these parts?

A: The primary differences are physical dimensions (rectangular versus square footprint) and packaging format (Tape & Reel versus Bulk). Electrical specifications are identical.

Q: Are both parts RoHS compliant?

A: Yes, both the 3362M-1-102RLF and 72XR1KLF are ROHS3 compliant.

Q: Does the packaging format affect electrical performance?

A: No. Packaging format (Tape & Reel versus Bulk) affects procurement and handling logistics only, not electrical or functional performance.

Q: What should I verify before substituting these parts?

A: Verify that the larger physical dimensions of the 72XR1KLF (9.53mm x 9.53mm square) fit within your available board space, as the original 3362M-1-102RLF uses a smaller rectangular footprint (6.99mm x 6.60mm).
