Substitute Part Grouping Explanation

Substitution for the 40FR15 is determined by strict equivalence across the following critical parameters:

• Resistance value: 150 mOhms
• Tolerance: ±1%
• Power rating: 10W
• Composition: Wirewound
• Package: Axial
• Temperature coefficient: ±90ppm/°C
• Physical dimensions: 0.406" Dia x 1.902" L (10.30mm x 48.30mm)
• Termination count: 2

The substitute part 40FR15E maintains identical electrical and mechanical specifications, with the primary distinction being packaging format (Bulk versus standard packaging) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 40FR15 and 40FR15E are functionally equivalent and maintain Active product status. Selection between these parts should be based on the following criteria:

• RoHS Compliance Requirement: If ROHS3 compliance is mandated, the 40FR15E is the appropriate selection. If RoHS compliance is not required, either part is acceptable.
• Packaging Format: The 40FR15E is supplied in Bulk packaging, while the 40FR15 uses standard packaging. Procurement volume and handling requirements should guide this decision.
• Inventory Availability: The 40FR15 has higher current stock (1034 units) compared to 40FR15E (739 units). Lead time considerations may influence part selection.

Both parts are suitable for direct substitution in applications requiring a 150 mOhms ±1% 10W axial wirewound resistor with ±90ppm/°C temperature coefficient.

Frequently Asked Questions (FAQ)

Q: Can the 40FR15E be used as a direct replacement for the 40FR15?

A: Yes. The 40FR15E is a parametric equivalent with identical electrical specifications (150 mOhms ±1%, 10W, ±90ppm/°C) and mechanical dimensions (0.406" Dia x 1.902" L). The primary differences are packaging format and RoHS compliance status.

Q: What is the difference between the standard packaging and Bulk packaging?

A: The 40FR15 uses standard packaging, while the 40FR15E is supplied in Bulk packaging. This affects handling, storage, and procurement processes but does not impact component performance or electrical characteristics.

Q: Does RoHS compliance affect component performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical or thermal performance. Both the 40FR15 and 40FR15E deliver identical functional performance in circuit applications.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts measure 0.406" Dia x 1.902" L (10.30mm x 48.30mm) and use identical axial package construction, ensuring mechanical compatibility in PCB layouts and through-hole applications.

Q: Which part should be selected for new designs?

A: Selection should be based on compliance requirements and supply chain strategy. If ROHS3 compliance is required, specify the 40FR15E. If compliance is not mandated, either part is acceptable based on availability and packaging preference.
