Substitute Part Grouping Explanation

The 41FR15E qualifies as a direct substitute for the 41FR15 based on electrical and mechanical parameter equivalence. Both parts share identical resistance value (150 mOhms), tolerance (±1%), power rating (1W), composition (wirewound), package type (axial), temperature coefficient (±90ppm/°C), and physical dimensions (0.126" Dia x 0.437" L). The primary distinction between these parts is packaging configuration and RoHS compliance status. The 41FR15E is supplied in bulk packaging and carries ROHS3 compliance certification, whereas the 41FR15 is RoHS non-compliant. Both parts maintain Active product status and are manufactured by Ohmite within the Ohmicone® 40 series.

Parameter Comparison

Engineering Selection Recommendations

Selection between the 41FR15 and 41FR15E depends on regulatory and procurement requirements. The 41FR15E is the appropriate choice for applications requiring ROHS3 compliance certification. Both parts are Active status components with equivalent electrical performance and mechanical compatibility. The 41FR15E bulk packaging configuration may be suitable for high-volume production environments. Inventory levels for both parts support immediate procurement without lead time constraints.

Frequently Asked Questions (FAQ)

Q: Are the 41FR15 and 41FR15E electrically identical? A: Yes. Both parts have identical resistance value (150 mOhms), tolerance (±1%), power rating (1W), temperature coefficient (±90ppm/°C), and wirewound composition. They are functionally equivalent in circuit applications.

Q: What is the difference between these part numbers? A: The primary differences are RoHS compliance status and packaging configuration. The 41FR15E is ROHS3 compliant and supplied in bulk packaging, while the 41FR15 is RoHS non-compliant with standard packaging.

Q: Can I use 41FR15E as a direct replacement for 41FR15? A: Yes, the 41FR15E is a direct substitute. Physical dimensions, electrical specifications, and mechanical termination are identical. Substitution is valid for all circuit applications where the 41FR15 is specified.

Q: Are there any package or form factor differences? A: No. Both parts use identical axial package configuration with dimensions of 0.126" Dia x 0.437" L (3.20mm x 11.10mm). PCB footprint and mounting requirements are identical.

Q: Which part should I select for new designs? A: Selection depends on regulatory requirements. For applications requiring RoHS compliance, specify 41FR15E. Both parts are Active status with current inventory availability.
