Substitute Part Grouping Explanation

Substitution eligibility for the 40F15R is determined by strict equivalence across the following critical parameters:

• Resistance value: 15 Ohms
• Tolerance: ±1%
• Power rating: 10W
• Composition: Wirewound
• Package configuration: Axial
• Temperature coefficient: ±20ppm/°C
• Physical dimensions: 0.406" Dia x 1.902" L (10.30mm x 48.30mm)
• Termination count: 2

The substitute part 40F15RE meets all electrical and mechanical specifications required for direct substitution. Packaging differences (Bulk vs. standard) do not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the 40F15R and 40F15RE are active products from Ohmite's Ohmicone® 40 series with identical electrical and mechanical specifications. Selection between these parts should be based on regulatory compliance requirements:

The 40F15RE offers ROHS3 compliance, making it the appropriate choice for applications subject to RoHS directives and regulations. The 40F15R, while RoHS non-compliant, remains suitable for applications without RoHS requirements. Both parts carry identical ECCN (EAR99) and HTSUS (8533.21.0080) classifications. Inventory levels are comparable, with 961 units of 40F15R and 934 units of 40F15RE available.

Frequently Asked Questions (FAQ)

Q: Can the 40F15RE be used as a direct replacement for the 40F15R?

A: Yes. The 40F15RE is electrically and mechanically equivalent to the 40F15R. Both parts share identical resistance (15 Ohms), tolerance (±1%), power rating (10W), composition (wirewound), package type (axial), temperature coefficient (±20ppm/°C), and physical dimensions (0.406" Dia x 1.902" L). The primary difference is RoHS compliance status.

Q: What is the difference between the 40F15R and 40F15RE packaging?

A: The 40F15R is supplied in standard packaging, while the 40F15RE is supplied in bulk packaging. This packaging difference does not affect the component's electrical performance or mechanical fit in circuit applications.

Q: Which part should I select for RoHS-compliant applications?

A: The 40F15RE is ROHS3 compliant and is the appropriate selection for applications requiring RoHS compliance. The 40F15R is RoHS non-compliant and should be used only in applications without RoHS requirements.

Q: Are there any differences in temperature performance between these parts?

A: No. Both the 40F15R and 40F15RE have identical temperature coefficients of ±20ppm/°C, ensuring equivalent thermal stability across operating conditions.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. The identical axial package configuration and physical dimensions (0.406" Dia x 1.902" L / 10.30mm x 48.30mm) ensure mechanical and electrical interchangeability in PCB layouts and through-hole designs.
