Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3362H-1-503 are qualified based on electrical parameter equivalence: identical resistance value (50 kOhms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), number of turns (1), adjustment type (top adjustment), resistive material (cermet), mounting type (through hole), and termination style (PC pins). All substitute parts maintain these core electrical and functional specifications. Mechanical dimensions and packaging formats may vary within the product category. RoHS compliance status and inventory availability are secondary considerations for component selection.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts meet the core electrical and functional requirements of the 3362H-1-503. The 3362H-1-503LF is a direct equivalent from Bourns Inc. with ROHS3 compliance, differing only in RoHS certification status. The TT Electronics/BI alternatives (25PR50KLF, 72PR50KLF, 82PR50KLF) provide equivalent electrical performance with RoHS compliance. Selection between substitute parts should be based on mechanical fit requirements, as these alternatives differ in physical dimensions and packaging format. The 25PR50KLF offers the highest inventory availability at 11557 units. All parts maintain identical electrical specifications and are suitable for direct substitution in applications where the original part is specified.

Frequently Asked Questions (FAQ)

Q: Can 3362H-1-503LF replace 3362H-1-503 in existing designs? A: Yes. The 3362H-1-503LF is electrically and functionally identical to the 3362H-1-503, with the primary difference being ROHS3 compliance. Both parts share the same resistance value, power rating, tolerance, temperature coefficient, adjustment type, and termination style.

Q: What are the mechanical differences between substitute parts? A: The 25PR50KLF has a square face of 0.270" x 0.270" (6.86mm x 6.86mm). The 72PR50KLF has a larger square face of 0.375" x 0.375" (9.53mm x 9.53mm). The 82PR50KLF has a round form factor with 0.250" diameter (6.35mm). The original 3362H-1-503 has a rectangular face of 0.275" x 0.260" (6.99mm x 6.60mm). Mechanical compatibility must be verified for your specific PCB layout.

Q: Are all substitute parts RoHS compliant? A: The 3362H-1-503 is RoHS non-compliant. The 3362H-1-503LF, 72PR50KLF, and 82PR50KLF are ROHS3 compliant. The 25PR50KLF is RoHS compliant. Compliance requirements should be confirmed for your application.

Q: Do packaging differences affect electrical performance? A: No. Packaging format (tube versus bulk) does not affect electrical performance. All parts deliver identical electrical specifications regardless of packaging type.

Q: Which substitute offers the best inventory availability? A: The 25PR50KLF from TT Electronics/BI has the highest inventory at 11557 units in stock, compared to 1244 units for the 3362H-1-503LF and lower quantities for other alternatives.
